SAR, Radiation, that kind of thing - Off-topic

You're probably not going to like this thread.
SAR levels... phone radiation, that kind of thing.
This isn't something I worry about that much but I've noticed some things since upgrading my phone over the years. Also, I've been in some areas with lots of radio waves and then in areas where there are very few radio waves and I have to say
If you think you don't believe in radio as pollution try standing in the middle of the rainforest where there is no power, no phone signal and you'll feel a sense of peace than cannot be compared to in an isolation tank in a city.
When you do this contrast a number of times I come back to the city and there's this sense of buzzing. Bear in mind this is from the ocean to a high rise apartment. I'm 100% sure I'm not imagining it, though I always accept the placebo effect where I could be imagining it, I've seen it so many times now and so clearly I'm adamant the human body's electrical nervous system can be effected by a lot/strong magnetic fields.
Basically I've noticed in years gone by that newer phones seem to feel like they're emitting more power than they did before when idle, but emitting less power when in use.
The reason I think this is because it used to take 20mins on the phone before getting a headache with a Phillips Savvy but that now takes now that takes 35-1hr on a Android gen of device.
However, if I use a modern phone and it's right in the centre of my chest I swear I can feel it. I wonder if there's been any double-blind tests on this. The thing is, I have WiFi on browsing like this and also 3G is at 2 bars but this feeling continues a little in 3G and a very tiny amount in airplane mode. This makes me think there's a magnet in there even during airplane mode. So, is the magnetometer always engaged like it seems to feel? Can we turn that off when not in use to save battery or is that proximity sensor always on?
As I say, I only don't like using the phone with it near my heart, I don't sense any problem anywhere else. Then again, more electrical signals come from the heart to the brain then the other way round so it could be a sensitive area.
Regards bluetooth. I checked out bluetooth headsets because they say the sweep spectrum should reduce area heating and so a SAR rating wouldn't even be possible. But that wasn't what it felt like. I still get headaches with bluetooth headsets, it's just greatly reduced. I figured it's pointless if it's not really working.
After a lot of research I found tube headphones and I use these just for longer calls.
The next thing I'm thinking is to optimise how the phone uses radio and sensors. This should be automated. I'd like to know how to turn off wifi when a connection drops rather than doing it by location in tasker for example. The same sort of thing should be done with GSM & 3G switching so what isn't needed is turned off. All of this meshes nicely with battery life - the 2 are synonymous. Why not enable call forwarding, carry a 2nd phone for GSM and only go out of offline mode for when you need to do something?
However, if my intuition is correct (this is one of the reasons I'm posting this thread), then SAR is just one of 3 radio signals coming out of the phone excluding electricity itself (EMF source).
So,
- so you get headaches during long phone call in the vicinity of the phone?
- do you find it easier to think clearly when on a wired connection compared to WiFi?
- have you thought about this much?
WiFi has been found to effect sperm mobility for definite but other than than it's all pretty unproven. WiFi seems to be lower power but somehow worse than GSM. Not sure about 3G.
However, phones are getting more and more powerful. 3G uses more battery than GSM and WiFi is an additional signal. Then we got 4G WiMax and all the rest on the way. Plus as I mentioned the seemingly minor development of the magnetometer. Is there any limit?
I never used to care that much until I experienced an electrically quiet place and then had to return to the drudgery of the city.
I still feel it's a subtle thing, but the effect for me can actually be very clear now, something that wasn't so for me in the days of GSM only, back then I didn't believe in all this at all.
Another thing I find is that typing on a computer without WiFi is somehow easier to think in a linear way without getting thoughts interrupted. I know, I know, this is a bit much now.
There is less energy coming off of your cell phone's radio transmitter than there is coming off of your computer screen that you interpret as visible light.. but the difference is that light bounces off mostly and if it doesn't it's burning your skin.
So, there's a load of info for you. Also some fixes too. Hopefully these things aren't a problem for you but also I hope to find people to discuss it with.
One thing I never understood was when training in the Air Corp we were taught to keep distance from UHF radios 25 years ago but then in the 90's and 00's phone radiation was not taken seriously at all and we still get people joking about it like it's taboo.
All this is very inconvenient for a tech addict. Obviously I've gone out on a limb with this thread. Be kind

Well, if you're "scared" of high SAR values, i would recommend you to get the Note. It's extremely low at 0.16 W/kg, and it looks like it's the lowest of all cell phones today. I personally don't care about SAR, but i can't complain if it scores well.
- Galaxy Note = 0.16 W/kg
- Samsung Galaxy S = 0.24 W/kg
- Samsung Galaxy S II = 0.33 W/kg
- Samsung Nexus S = 0.50 W/kg
- iPhone 3GS = 0.79 W/kg
- iPhone = 0.97 W/kg
- ZTE Blade - 1,35 W/kg
- iPhone 3G = 1.38 W/kg
- Sony Ericsson Xperia X10 Mini Pro = 1,61 W/kg (!)

Ah but one of the points I'm making is that the SAR is only for some of the function on the phone. I think it only covers 2G or 3G during a call. Afaik it's not covering WiFi, WiMax, sensors and also EMF which shielding is there to shield against you see. I guess what's needed is more info on SAR because while I know it's basic I wonder how basic it is. Holding a EMF meter next to a phone would be interesting too. In fact I have another android now so when I got this i9000 fixed I'll hold
Another point I am making is that according to the SAR values my i9000 should be better than my old Phillips Savvy but what I'm saying is that this is not what it feels like.
My guess for why this might be could be because a SAR rating only measures local tissue heating as if the amount of radiation is the only factor. What I'm saying is that it's not simply the peak power output that's important but also what is being transmitted.
I believe WiFi is lower power but it's closer to the frequency at which the human nervous system works.
Thanks for those SAR values, that's interesting. I don't think I'd be able to tell the difference between those values and to be honest I'm not that bothered. It's more of an interesting thing to talk about for me. The iphone looks interesting though, it would be nice to actually use one and see if it actually makes a difference in everyday use.
One thing to clarify is that while I'm totally sure that I can feel radiowaves I'm not too sure that it makes much of a difference to health, especially seeing as flying is a massive dose of radiation and so on.
More more thing to add, the signal effect drops off almost exponentially so if you hold it just 1cm from your ear you've made a reduction. I also prefer to keep it away from the centreline of the body, away from the spine.
That said, I wonder if SAR ratings are a cynical way to sell more phones, no?

Wales? East Anglia?
Arabian desert? Never noticed any difference.
Mobile operators in the UK have run their own tests where they've told people that a mast is active (and received assurances that those people can feel the EMF resulting in headaches/palpitations) when the masts have actually been off.
In the 70s and 80s it was electricity pylons being blamed for cancer, now people have grown up not thinking twice about them hypochondriacs have latched onto mobile masts, wifi (remember those "leave a chicken breast on your router and it'll cook" stories?), and now they're starting to blame wind farms.

Honestly, your perception is likely heavily weighted by the fact that in cities, etc you know all those devices are surrounding you. Most of what you are feeling is psychosomatic all things considered. Whatever the case, the only way to know will be long-term, properly-executed studies where perception biases can be overridden.

Maxing Out Your Overclock!!

I know when some people try to overclock past a certain point it does not let
them, for example it gives them a fuzzy screen or just freezes. Well I came
across an idea which did work on my Wing.
The whole concept is keeping your wing cold, sort of like when you overclock your computers CPU you want to keep it running as cool as possible.
Before starting!
I am not responsible if you damage your device, or break it!!!
Heres what you do to get those high overclocked settings.
First off you want to monitor the temperature of your CPU.
You can do this directly from battery status.
Go to indicators make sure thats checked off, as well as temperature.
This will then display the temps on the today screen.
Normally it displays Celsius, if you press on the Temps it then displays
Fahrenheit.
Now you want to take your phone and put it in the freezer.
Yes I said the freezer lol.
You can wrap it up in a paper towel or just put it in regularly up to you.
Leave it in their for 1 minute and monitor the temperatures.
Make sure to check it constantly.
Now once the temperature hits 0 degrees Celsius/ 32 degrees Fahrenheit
remove it from the freezer and set your clock speed. It should not freeze, or
make a fuzzy screen. Leave it at that clock speed and put it back in the
freezer, monitor it for at least another 5 minutes. After that take out your
device wipe it down and soft reset it.
Once your done the overclock should stay at the set speed.
This worked for me and I hope it does wonders for you.
Thanks for reading!
Possible water damage
Nice thinking, you've just took overclocking to the next level.
But aside from the warning on overclocking > be carefull with putting your herald into the freezer. Because you Herald is not sealed airthight, there will always be a small amount of air inside the apparatus. The moment you put your device in the freezer the air and its natural humidity will freeze. As soon as you take out you device the frozen air/humidity will unfreeze and cause condensation within your device.
This means there is a (small) chance you will get corrosion on vital parts of your device causing it to mall-function.
Because the time is limited the chance is small, but always present. (this might even happen during winters when you change from an outside temperature to a inside temperature or during rain).
Although unlikely to happen often, it happend several time while I worked at a phoneshop.
Good luck!
Um. Wow. Don't Know What To Say. So like what happens when say you're out the house for 10 hours and the device heats up? Are you saying that the cold freeze will trick the device into thinking it's really colder than it actually is? Or is a stay at home and close to the frig trick?
Perhaps not the most relevant comment but does it really make that much of a difference?
I had mine set to 273mhz for a week or so and then turned it off for some reason and then forgot to put it back on; and I must say that I really didn't notice any difference. The was still significant lag between switching portrait-landscape for example.
And I should point out that one of my biggest disappointments with this phone is the speed, or should I say the lack of.. So it feels to me that if there would be a big difference I should have noticed because that is whats bugs me the most with the phone..
Thanks jappo for that heads up.
Now to dkb218 I don't appreciate your sarcasm.
I never stated that it "tricked" your phone into thinking its colder than it is.
The reason I shared this is because I used to never be able to get past
247Mhz on my Wing I tried this out and now I am at 286Mhz stable.
To ultrajakob, overclocking does make a big significance in speed.
Of course you will still see lag from when switching to landscape mode,
but it will not show as much. I have my wing set to 286Mhz and the switch
is almost instant with no lag. Another thing that can affect it is if you
have a lot of today plugins, try cleaning up your today screen a bit.

Sarcasm = "Sure and if you put it in hot ice you can overclock to 1298!"
That's sarcasm. My question was valid. How does this make the device think that it's colder than it is? Why would this work? You post seemed rather like backdoor science and I find it hard understanding how it worked. I know that one of the keys to overclocking is keep the device from overheating. What happens when your device is no longer in a cold state? Can you answer that without thinking this is sarcasm?
Once again I don't know if you have trouble reading, or understanding but I never said that this tricked your device into thinking its colder than it really is.
The temps never heat up past 36 degrees Celsius/100 degrees Fahrenheit thats when charging.
To tell you the truth I don't know how this worked but its just one of those things that did.
This is what I think:
Once you set a speed and its stable without freezing/fuzzing up it stays at that.
Even when the device heats up the temperatures does not change much.
::EDIT::
Also when overclocking the temperature stays the same as if it was set at 201mhz,
a change in 85mhz should not overheat the processor.
its a good idea in theory but it is probably bad practice. this extreme change between hot and cold WILL cause condensation to form inside the device. thats why people don't just hook up a refrigeration unit to their PC, they use water cooling (which is a sealed system). not only could the water short the circuitry, but it could put permanent water marks in the lcd. i guess if done properly you minimize effects, but still not a good idea. it could even void the water sticker if you have that on your device, which could keep you from your warranty (if you have one)
I was thinking what if it was to be put inside of a zip lock bag?

nope, air is still in a zip lock bag. even a vacuum sealed bag will leave the air inside the device. and, assuming you have a strong enough vacuum, attempting to vacuum all the air out will crush the device. good idea though. i think the best bet would be some sort of way to slowly cool the device and slowly warm it back up, to reduce condensation. its like the parable of the boiling frog. thats how you need to trick it with out damaging it.
I like the way you think.
So what temperature is too high? Or, to be clarify my question, what is a safe operating temperature range. Also spjr, maybe the freezing messed up your temperature sensor. It just doesn't seem logical for your process to work.
Thanks,
Joe
I guess this kind of like in the movie real genius, where Val Kilmer figured out how to make the laser run by cooling it with ice ... the only problem was that it would destroy itself after one use ... I hope that doesn't happen to your phone!

I don't appreciated your tone their Mr. Science. You little experiment would suggest that somehow the device is no longer keeping the correct temperture after a slight deep freeze. Something is happening to make the device overclock to speeds that it didn't do prior to the putting it in the freezer. That would suggest that the gizmo that measures temperture is being "tricked" into thinking that it's colder than it is after removing it from the freezer.
Can you understand why I use the word "trick" now? You seem to have an aversion to it for some reason... or maybe you didn't carry the line of reasoning that far.

thats fing funny. i once stuck my phone in a microwave to blow it up so i could turn it in under warenty for a new model lol only takes like 5 seconds if that
Ok my phone is stable at 299 so I'm gonna try this to get a 312 overclock. I'll let you know my results.
Ok it is successfully clocked to 312 after a soft reset. Now to just see if it holds it. A side not for everyone would be to fully charge your battery before doing this. I started mine with about 40% and when it got done with the soft reset it was at 1%.
*update*
No good, froze up after a 10 minute phone call although it did hold up for the entire call. Too bad.
If you Brick your Device.... Try this

dont want to be harsh but do not ever say something like this again
as your knowlage of cpu's seems to be lacking
a 1 degree change can end a cpus life... its all in the manufacturing of the cpus
thye are made then speed tested and rated/ then set to there prime speed...
these phones have simple cool plates on them... small coper takes heat and removedit.. the phone can overheat quite fast... even at stock speed.. there are a almost infinite amount of ways this can happen... even with the humidity around youe location
go ahead and oc the phone... i run mine at 238 i think cant remember..
but as with all of us who overclock it... we run the risk...

Nexus 5 initial impressions from an iPhone 5 user

Background: Ever since I switched from AT$T to T-Mobile last month, my iPhone 5's battery life has taken a huge nosedive for the worst, to where it can easily lose 1% every 2-3 minutes, Wi-Fi on or off, and even if airplane mode is on but Wi-Fi is on (Apple Store won't replace it since it's 60 days out of warranty, and a new battery honestly probably won't help since the capacity and other diagnostic readings are showing signs of a normal battery). Popping my AT$T SIM back in, I immediately get much better numbers. Either T-Mobile's network sucks the crap out of batteries, or the phone has yet to be optimized for the network. I'm thinking it's the latter, because I've used other T-Mobile phones, such as the LG Optimus L9, and battery life was really good. Since the Nexus 5 is a very affordable off-contract device, I decided to give it a try.
I understand that the battery life is itself questionable for the Nexus 5, but it supposedly gets better as time goes on.
My white 16GB Nexus 5 arrived yesterday (ordered it on the 6th when it said it'll ship between 3-4 weeks). Using a ghetto paper-based mold for my nano-SIM, it worked just fine in the N5's micro-SIM slot.
It took a number of hours to eventually get things the way I like it, but here's my current setup (the icon and folder setups are nearly identical to how I had them on my iPhone 5, and every third-party (App Store) app I had there was also available on Android, or at least a good alternative was available):

Overall, I'm very happy with Android 4.4 and its general performance on the N5.
So, some complaints.
First, LTE. On my morning commute, I noticed it completely lost a signal (no bars, just an outline) three times in areas where my iPhone 5 would have at least 2 bars (dots) of LTE. I would at least expect it to drop to HSPA+, but it didn't do that... In the building I'm in, I always got at least 3 bars of LTE on my iPhone 5. My Nexus 5 can't seem to hook onto it, even after flicking airplane mode on and off a few times. It's instead connected to HSPA+ (fluctuating between that and 3G when idling, as expected). Yes, HSPA+ works, but I want LTE if I have access to it, which I do. EDIT: Changing the data network from LTE to 2G, then back to LTE brought LTE back. EDIT 2: Well, where I've been at for the past 10 minutes, I get a full signal of LTE. It randomly decided to drop to full HSPA+/3G.
I always also hoping that general compatibility with T-Mobile was better. The raw decibel signal readings do seem to be in my favor, but the LTE problems and prior signal drops are hopefully things that won't happen again.
Next, battery life. Yes, as mentioned, I know that it's supposed to get better. To be honest, my initial battery life numbers don't seem too bad. Here are some of my initial numbers (N5 came out of the box at around 80% battery, used it down to 5% before charging it all night):
At that screen on rate, I'd estimate about 5.75 hours of total screen on usage, and 9 hours of total standby. That's much better than some of my recent iPhone 5 numbers, and I hope that they can increase. Battery life is really the deciding factor if I keep the N5 and sell my iPhone 5 or not.
I've already gone through all of the battery saving tips (turning Wi-Fi auto search off, battery saving location mode, disabling OK Google, etc.). My usage isn't too heavy, but I do leave Wi-fi OFF (yes, off), get hundreds of texts, checking and replying to them, using Twitter (Tweetings), listening to music through headphones (PowerAmp), checking email automatically every 15 minutes via K9, dealing with those from time to time, and opening some pages with Chrome.
Next, the speaker. I was expecting it to be loud, louder than my iPhone 5, but it's noticeably quieter. I guess there's a hardware hack for it, but I'd rather avoid that, should I end up returning the thing. It sounds clear, and seems louder in certain apps than others (even if the volume is up all the way). Not sure if it needs to be broken in first.
I just noticed that music through headphones doesn't get very loud either, even with things turned up to their maximum values in PowerAmp.
I've yet to take a picture with the camera, and I heard it could be better (and probably will with a software update).
Speaking of software updates, I imagine Google could easily improve on almost all of these areas, including battery life?
One of my concerns was whether or not I can deal with the larger phone for one-handed operation. And really, I haven't had any complaints there.
Overall, I'm very satisfied with it. Just anxious to see what my battery life numbers will be as time goes on.
Battery life probably won't get drastically better. You just need to see what kills your battery the most. If there are things on in the background that your not using such as an app that would save battery life. But most likely is just the screen

If you can live with Google Play Music for listening to your music, it should use less battery then poweramp by using the special kitkat dsp audio engine.
If you don't have stable LTE, it will really suck the life out of your battery. I just run HSPA+ most of the time and my battery life is ridiculous now.

One big thing I really like is when songs crossfade between each other, which the Google Play Music app doesn't do. PowerAmp's equalizer and other audio adjustment settings are things I can't really go without anymore. Battery life when using it seems fine (for now).
LTE where I am is generally pretty stable. I'll do some tests with LTE off since that will probably help a bit (didn't matter on my iPhone 5, since the battery life would decrease at the same rate regardless of which type of data connection I'm on). Think a software or radio update would help?
You are complaining about nearly 6 hours of battery life?!!? If I get a Nexus 5 and get that much screen on just browsing, I'd freaking celebrate!
Let's not forget that you started at 80%!! EIGHTY PERCENT!!

Well, my iPhone USED to get really good usage numbers under similar usage scenarios.
I've got to admit, I was expecting another "iPhone 5 is way better than Nexus 5" rant...
Kudos to you sir, I thought you made a pretty good review and fair comparison between the two.
I've been having similar issues on T-Mobile as of late, so I understand where you're coming from. The battery and network connectivity issues are most likely on their side.
As for software issues, the sound output being drastically different per app will likely be fixed in an OTA soon. The camera actually exceeded my expectations on a recent family outing to a Texans game last weekend, with HDR+ it takes amazing pictures! The autofocus could be faster, but I'm sure that'll be addressed in an OTA as well.
Thanks for sharing your thoughts bud, it's not often we get unbiased opinions here... It's refreshing to see a review by someone who isn't an iOS fanboy or Nexus apologist.

Battery life is incredibly subjective and can vary wildly from user to user. Location, carrier, usage patterns, etc. are different for everyone so it's hard to definitively predict battery life on the N5.
My experience? My first week I was incredibly worried because battery life was significantly worse than my GS3. Granted, I was playing with it a lot and testing out different things, but I was averaging about 3 hours of screen time and scraping about 12 hours of total life. Pretty terrible for what I was used to. I will say that when I was testing out the Moves app, to test the movement tracker, this absolutely slaughtered my battery.
I lived with mediocre battery life for a few days, then when Franco came out with his kernel (I believe I started at r10) I flashed it and then started getting insane battery results. Each kernel update has gotten better (now on r14) and I'm finally happy and able to easily make it through a full day.
For the past week, I usually take my phone off the charger at 7am and it goes back on at 11pm with around 25-35% remaining. During this time my screen on time is between 3-4 hours. So that's 16 hours with a quarter of the battery remaining and a decent amount of screen time on. I'm very happy.
I'm assuming a custom kernel requires a root, which then requires everything to be wiped? I wish I knew that prior to getting everything setup. Probably won't get into any of that for a while.

It's also not similar conditions when the iPhone 5 has only a 1,440 mAh battery, that's something like ~63% smaller than the Nexus 5's battery (which many of us already find to be disappointingly small compared to other Android flagships).
I'm a hardcore Android user, always have been since I owned an OG Droid and Nexus One, but I concede that whatever Apple does with iOS and their SoCs to squeeze so much screen on time out of the tiny little batteries in the iPhones is pretty impressive.

A custom kernel doesn't technically need root, but it does need the bootloader to be unlocked which is what wipes the device.
You can try to backup with an app called "helium" which apparently backs up a fair bit.
I also saw a thread to unlock bootloader without wipe. I didn't read it though. Possibly in themea and apps subforum. Try a search of xda at the root if the n5 forum

Could you tell us more about your experience on Android vs iOS? I had an iPhone 4S prior to switching to Android, and aside from the consistency of the UI and fluidity, there isn't much else that I miss. Oh, maybe the excellent color accuracy of the iPhones (especially whites, which aren't too blue). The biggest thing that I was glad about dumping was iTunes, followed by iOS restrictions on what you can and can't do.

Rooting doesn't require a wipe, but unlocking your bootloader does. Step 1 when aquiring phone, unlock bootloader, optionally root if you want, then set up. Bootloader unlock is most important for custom kernel.
Did you try viper4android for general sound enhancement. Don't have mine n5 yet - but on other phones it is amazing.
You can find viper in the play store.

True. Completely different hardware and os makes any comparison pointless.
I actually think the N5 battery is great. Its bigger than my S3 my 200 mAh but it lasts much longer proportionally.
The best way to make the decision between the 2 is to see which is a better fit for "your" usage and habits, which you enjoy the most and whether the battery is "enough".
For me, an iPhone battery would last days,.but it doesn't suit me.
Best thing is to consider battery last. Let passion make the decision

I'm actually relieved and excited to hear that. I had an S3 for many months and it was the first smartphone I've ever owned that I felt had really good battery life.
I'm on a Galaxy Nexus on Verizon right now, which is notorious for having insanely abysmal battery life, and it was like a slap in the face compared to my S3, which easily lasted all day.
So I figure just about anything will be better than what I'm on now.

While even Android 4.4 on the Nexus 5 could be smoother in terms of frame rate. I thought I'd get annoyed by it, but it doesn't bother me much. I kinda miss iTunes, keeping syncing things organized within one central program, but I rarely used it.

I'll have to disagree there. They're both phones that can do similar things, and both have similar hardware features (although they obviously differ). When usage scenarios and network conditions are as close as possible, only then can the battery life really be compared. So, I think that it's appropriate in my particular case.

My comparison is like for like here. My network doesn't yet offer lte and my s3 was not the lte version. Bear in mind my s3 was quad core 1.4Ghz so im not sure how my S3 compared to yours.
But my N5 I am doing 16 hour days (8 hrs low signal area) with 4.5 hrs+ screen on. I could get that on my s3 if I didn't leave the house but a normal day would be 3 hrs on s3.
I am undervolted by 50 and using greenify though

Fair enough I respect your disagreement. Although for me I disagree that they do similar things too. On the face of it they do, but for the hardcore of us I don't feel that's true. Not to spark an iPhone / android debate here (so this will be my last word on ios) but I see ios more as a "feature phone" than a "smart phone".
If the iPhone does all you need and you can get better battery, its a no brainer. Its just the os work completely different. The n5 is much more powerful and bigger screened and the architecture is incomparable.
On the face of it they do the same "calls, emails, web and some apps" but the comparison stops there I feel. It depends how involved you wish to become.
As I say, go with your heart on which you prefer. Take battery into consideration but don't let it rule the decision. Go for what suits you, not what anyone else says

So I've convinced myself to wipe & root later, backing up with Helium and the normal Google backup (for system settings and such). That should get me mostly setup the way I had pre-wipe, right? I should have some time this weekend to just start from scratch again, but would definitely like to avoid most of it if possible, which it seems like it is.

WiFi strength, range, and throughput

Rate this thread to express how you think the HTC 10's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
I am getting drop-outs on my WiFi connection even when feet from the router. The strength is OK but it drops connections, and when making WiFi-based calls the phone complains that WiFi signal strength is low (even when max bars! Clearly this needs and fix from HTC as others are reporting this too.
when I use the normal wifi from my router I seem to have issues but I'm on very old firmware still from Verizon 1.19. I hear the update helps out with wifi issues. When I connect my to my router using the 5G connection it works flawlessly.
I find the wifi strength is not top notch. Very easily it drops its speed. Using ICE Rom.

I found this fault on previous HTC phones that I've dealt with like the M8 M9 all had weak Wi-Fi connection and range.
Sent from my SM-G935T using Tapatalk
I vote excellent. I walked away from our apartment the other day and my 10 clinged on to it's dear life and maintained 1/5 bars where my M7 and missus's G3 just went: nope.
I'll have the "ultimate test" for my 10 next Wednesday. Going to school and in our "lab" we have a WiFi router. This lab is basically a bunker, a bomb shelter.
My M7 could pick up the WiFi from there (with the door closed) fine in a couple of locations around and near the bunker. It's going to be interesting to see how well my 10 can pick it up.
Wi-Fi singal to me is a great, but the speed and connection seems quite off. At times I can use my laptop while my HTC 10 is connected to the same Wi-Fi connection and my laptop speed will be great, but the HTC 10 seems quite sluggish. Additionally, sometimes I will get an error notification with Wi-Fi calling, and sometimes I'll get dropped calls when I have great Wi-Fi signal.
WiFi signal is absolutely horrible for me. Most of the time I only get 1-2 Bars except im really close to the Router.
My Tablet and other phone always get way better Signal strength.

Wifi on HTC 10 is the most horrible implementation I have seen on any device. If you think your wifi is great, go contribute your debug logs to this thread: http://forum.xda-developers.com/htc-10/help/wifi-constant-suspend-resume-leading-to-t3392562
Vote on that thread only after doing the diagnostics, not by "oh, my wifi is great because I can browse on my phone".
I had issues before update 1.80.401.1: connections never seemed stable
Now on the update I've nothing to complain about, throughput is good, ping is stable and the wifi never seems to drop again.
Roaming between access points is also great, no drops there as well.
The range is fine as well. From the house to the garage (about 30m away) I still get a good enough signal to use internet, watch youtube etc.
That's through 2 brick walls and a garden with trees
Wifi range on this phone (HTC 10) is atrocious. The phone is basically useless to me. At home, it refused to connect to my 5ghz band and would only connect to the 2.4ghz band, unless I was within 5ft of the router.
We are currently in Costa Rica on our honeymoon, and while my HTC 10 remains in the hotel room safe 99% of the time while we surf, explore etc., the few times I've needed it it absolutely refused to connect to any of the 3 wifi networks here. Meanwhile, my wife's Galaxy S4 connects to any of them with no issues and gets 20mbps download speeds. My Macbook Pro has no issues and two other people we've talked to have had no issues with their iPhone and LG G4.
I wanted to love this phone but it's given me nothing but issues when it comes to network connectivity. I made the last second decision to leave my Nexus 6P and bring the HTC 10 in an effort to have a smaller phone with me during this trip, but I completely regret it. As soon as we get home the sim card will be pulled and the phone will be shoved into a drawer until another worthy phone comes along to use my next JUMP! Ondemand upgrade on.
It's too bad HTC is making the next Nexus phone. Because I sure as hell won't be buying it after this B.S. experience.
Also, for reference, when I got the phone from T-Mobile I unlocked it and flashed the U.S. unlocked RUU firmware/ROM for faster updates. I had these issues on the 1.53.617.5 RUU and they persist after the latest 1.80.617.1 update.
@sn0warmy do you have the uh oh warranty with 1 day replacement? Because I wonder if this is a hardware issue as some people report good WiFi.

I'm not entirely sure. I do pay for the accidental coverage through T-Mobile and I'm sure I could use that to get a replacement through them (they've always been great in giving me replacements when requested). But I've seen so many people with the same issues, who report the replacement doesn't solve the problem., that I almost just don't even want to bother.

My HTC 10's wifi reception and speed is noticeably worst than my LG G3, and MUCH-MUCH worst than my 6 years old Dell Vostro 3350 laptop. At first I thought that my specific unit is defected, and went back to the store to replace it. The store's manager claimed that "it is what it is", and allowed me to examine and compare it thoroughly to his Smsung S7. They performed similarly. Some consolation...

Totally agree man, my old M8 was WAY much better compare to my HTC 10 unfortunately.
I use to get almost full signal in my house at the second floor with the M8, with the HTC 10 cannot even browse.
I have to say this is the only thing that I don't like of this phone, hope a new firmware will do something.
Yeah, I'm on the latest OTA, 1.80 and Wi-Fi is better, but not as good as my old LG g3. Just enabled 2.4Ghz only, and it feels better
Sent from my HTC 10 using XDA-Developers mobile app
Agreed, reception is terrible, I bought the unlocked t mobile version through htc, am on the latest update 1.80.617. I am currently sitting in a hotel room with crappy wifi service, but next door there is a walmart with a strong signal and I am connected through that on my laptop with 4 bars, but I can't get the 10 to connect at all.
Oh look, there is still one bar left.... no reason to switch then....
GTFO WiFi... GTFO
This is well know android issue that has nothing to do with htc.. Android has wifi roaming issues, same happens with samsung ore oneplus...

Which Hardware Revision do you have?

Hi,
After reading in another thread that there are different Hardware Revs i took another look at my Box and found out that's true.

So how many different version are there? Someone said he had Rev 3.
How is the distribution? Timebased? and How many of each...
And most important, what's the difference.... anyone knows anything?
So, as you can see in the Picture above, i got the H8216 in Rev 2.
What do you have?
I don't know about differences but I have revision 3.
H8266 revision 3 here.
I'm not sure if I am not noticing it, but I do not experience touch screen sensitivity issues when I play games or maybe they are minimal. Granted I play rhythm games and mobile rpgs, not fps or fighting games so maybe its just me.
H8296 Rev 2
H8266 Rev 3
This thread is pointless if revisions are not linked with specific comparisons in behaviour.
Revision 1, and I'm having massive heat issues. Recording videos, especially with SteadyShot, HDR and 4K activated is stopped after 7 to 10 minutes usually, because the phone got too hot. I'd like to know if later revisions fix these issues.
Does Revision 3 fix the hardware issues?
I have Deep Green H8266 (Rev 3).
I don't experience too much heating issue and don't experience touch sensitivity issue either. Battery life is great and can be really amazing, a lot of time (reaching the point where I'm struggling to drain the phone's battery at night, just because I want to charge the phone at 15%). It is also lightning fast, superb gaming performance, and has great multitasking performance, too.
H8266 Rev 4 here, just bought it a couple of weeks ago after frying my Z5p, I had no intention on getting this phone, was going to wait til the end of the year to see what Sony will offer but necessity obliged ?
Absolutely zero issues, no heat or screen sensitivity as other mentioned, this thing stays cool and is lighting fast, battery life is insane, crossed a few times 10+ hours of SOT...just waiting tight for a drm fix to root and xposed (whenever that is)
The only thing that bugs me is the esthetic of the phone, not a fan of the back side at all (finger print sensor works pretty damn well though, still prefer a side placing)

Interesting. I'm not getting anywhere close to those battery times either. Can you run the GeekBench battery test? I'm at 4 hours and something...
I will ask the support to repair my phone.
Switch it to the latest hardware revision.
And see if this fix my touch screen issue.

Impossible physically. The battery is not big enough to sustain that long of a SOT no matter how efficient you claim to be. unless sony changed the battery capacity in their latest revision, conning people who got earlier revisions.
I haven't had any of the issues reported, the phone never seems to get hot either but I don't play games very much and for the time that I just got slightly warm. I agree with the battery life, it's really amazing compared to everything else I've ever owned.

I've been on xda long enough and I'm not the type to post nonsense ?
This pic below is not from my phone, it's from the xz2 thread on Esato, so you can see that I'm not the only one either...I didn't take a screen shot of mine when I crossed 10+ hours (I will next time)... I said that passed it a few times, mostly range in the ≈9+ hours...
I don't game, few accounts with push notifications and an email client with 3 imap notifications (so those run in the background constantly)
This one below is from my phone...I'm at 1.5 hours of SOT with a 12% down from full charge...you can extrapolate the end results ?
System optimization is an important factor, not only battery size...they did a great job with the xz2...

and WHAT exactly do you want to test? We don't know what they changed, might the supplier from glue which holds the Screen on the phone, might be the a different speaker/microphone inside or something else smaller.
Else we wouldn't be a rev4 already. Changing something during production is no small feat...

Lol.
The Battery inside the XZ2 has:
Min: 3060mAh 11.6Wh
Typ: 3180mAh 12.3Wh
So i've measured the powerdraw for Screen+Phone Idle/flightmode:
Minimum Brightness uses 0.49W
Maximum uses 1.83W
Screen Off uses 0.24W
Doing the Math even at full brightness if you use your phone as E-Book reader you could reach 6h 45min At Minimum even over 25h!
So yes, it is very well possible.

Hm. Before the XZ2 I've had a Xiaomi Mi 6, which impressed me more in terms of battery. Smaller screen, bigger battery (and much slimmer phone).
And IMHO it's not better, perhaps worse than my LG V20. I did take a lot of photos, which does seem to drain the battery badly.
I really wonder what they have done through the revisions. It seems clear to me now that revision 1 had some serious flaws (or maybe my unit is defective), especially in terms of cooling.
Rev 2 i have
Wat is exactly the point of this... More info please and can you explain us what Rev 1, 2 and so on is and what it mean ?

No one except for Sony probably knows. But it is interesting to see, which revisions made it to the market and which didn't. And if people report on issues with their phone, we can at least figure out a bit what was fixed. Also now we know there are 4 revisions so far. Mine is revision 1 and says demo only, not for sale. So maybe it is also possible to find out when these phones were released.

[FIxed]Note 9 vs p20 pro Download speed

I was feeling there was an issue with my Note 9 compared to my Note 8 and P20p Thus i decided to do a speedtest. the phones were at the same place and nothing was using the bandwidth. Surprise. look at the video, and you will see. (N8 and p20 came with the same results).
I would like to ask some of you who already have it to test it against other phones to see if i'm the only one with this issue. I have the latest firmware on it and didn't test it before the update...but this is really not normal. I also feel it's just "slower" in general than the p20p...
check this link for the video
Upload video on Youtube plz
Yeah, as a network engineer I'm not going to touch random files on a Dropbox. At least link a speedtest.net result or the image.
I have my note 9 coming on Friday so I can put some effort into getting the optimal wireless connection (there's so many variables involved, I'm a wireless network engineer working for a wisp so all in my realm of knowledge) and give it a test.
I'd be very surprised if its a downgrade compared to Huawei, Samsung spend a lot of time on their LTE radios, now running on CAT 18, with MIMO, for a theoretical bandwidth of 1.2 gbit/s. Will know for sure Friday!

Can't find info on the chipset in the S9+, but I can find that they have MU-MIMO and 1024QAM, so it definitely should be quicker if you have a router supporting the above.

Since the test was on WiFi, and not LTE the work Samsung has done on the modem is irelivant.
My question is, are they really on the same network? The results make me think that your Note may be hitting the 2ghz network not the 5ghz network.

Read the thead mate, it was a cache issue. I was only pointing out Samsungs dedication to connectivity, and I did follow up with somewhat comparable specs for the radio.
It could be a number of things, potentially more sensitive radio in the note 9 that struggles to handle interference, etc, it'd be pretty obvious to be on the wrong network.

It could be a number of things, potentially more sensitive radio in the note 9 that struggles to handle interference, etc, it'd be pretty obvious to be on the wrong network.

Perhaps Mate, you need to clarify... first you wrote "shocking!" in the header of the thread, then in one post you said "Strangely i was able to when i cleared cache...." which didn't mean anything to me, and certainly not that you discovered the problem.
And no... being on a 2ghz network vs 5ghz network can be an invisible decision made by the hardware, and many networks are using the same network name. So it wouldn't necessarily be obvious.
For example, in my house, the network ID is "MyHouse" for both the 5ghz and the 2 ghz networks... the Chromecast is on the 2ghz network, and my phone is hitting the 5 ghz network. They see each other and is seamless.
Dude, I don't know one router that has the same SSID by default for both networks. Someone changing the network should notice the difference then.
BTW, I'm not OP, just someone helping.

Definitely not an issue!
http://www.speedtest.net/my-result/a/4187326458
Though i would add my results here also, Verizon snapdragon model. Definitely seems like something is going on with your test. http://www.speedtest.net/my-result/a/4188275993
so you guys testing your wifi speed using your isp network is telling us what exactly?
at best you should test locally but even there. if your network equipment is not on pare then again your testing with too many faulty variables and it won't show phones true potential.
ignorant people would state that a phones wifi has issues because upload speeds sucks compared to DL or just both seem slow.
but in fact what sucks is ISP internet package and not the phone. obviously other parameters like specific servers the test is being done on can co tribute to faulty 'online' test results.
so we have a few factors which make tests like these irrelevant:
-****ty internet package subscription
-****ty test server
-****ty home network
for cell data tests, well we need good weather and be near a cell tower.
but again this proves less concerning phone's capabilites as throughput but more towards signal quality.
and the average will be provider's coverage. how many towers they utilise and your signal strength in general in most common locations you visit.
*btw OP dude, do everyone a favor and correct your thread title...
i was tested on 4 devices, Note 8, XZ2, Iphone X and Note 9, so seem XZ2 always faster and winner

Sorry dude, but there's so many more factors to be able to throw any of this out. I really hope no one is taking this that seriously.
For one, I have no idea about the noise floor (background EMF noise level) on whichever frequency people have decided to run your AP. (Be it 2.4 or 5ghz, and then which channel, 2.4 ghz only really has three channels, 1,6,11, with the other channels just being overlaps. 5ghz has a lot more but usually everything is on 5180 (channel 36) due to DFS above 5250mhz in mos6 countries. Chances are all of you are suffering from interference.
Then we could talk about MIMO. Each MIMO chain nets you +3db so routers supporting MU-MIMO could see big signal increases just from both devices having multiple MIMO streams going on.
S9+ (and probably the note 9) supports QAM1024, essentially fitting more data over a link at once to the risk of needing a higher signal to noise ratio (this is where noise floors and interference comes heavily into it)
Every situation is unique, I think we should try and explore but please share your enviroment, I.e your router, where you are (apartment, house, city, rural etc) and then we can only start making sense of things.

but you have to agree that it is folly to report wifi speedtests using home internet and its limitations by the ISP as being a way to gauge a phone's capabilites.

No, I'm not sure I agree.
If you cable into your router and do a speed test, and use that as your comparison point, I don't see the problem with using a home connection to test.
I don't know what limitations you're talking about, in my experience for speed testing you're routed into the DC where your ISP has its presence then either a speed test server within your ISPs DC network or one right next to it in the same DC.

Now if you're using the router supplied by your ISP, whole different story.
