[Q] MHL display low resolution problem

Hi! I am having some problems with my brand new HTC One - I connected it to my 1080p monitor using an MHL -> HDMI adapter(one of the cheap ones from Amazon) and the resolution of the screen is locked at 640x480 60Hz. There is no option on the phone to change it.
I used to use the same adapter with my Galaxy Nexus before, and it would display 720p just fine - and since the HTC One has a full HD screen I expected to use Full HD resolution over MHL as well.
Is that possible? Has anyone done it personally?
Cheers

Doesn't quite work like that m8, the S3 had similar issues, I tried on different TV's and got different results, on my LG 47inch 3D TV i get 1080 at 30hz and on my panasonic viera 32inch 3D TV i get 720 @ 60hz. So not 100% as to why but try a different TV, you may get better results, I personally couldn't find a setting to alter it.
I've been holding off buying an MHL as there was latency issues causing delay on the S3, I didn't want to waste money and get my hopes up if it was going to be the same thing on the One.

I bought the MHL 5 pin adapter few days ago and returned it today because it was simply crap. The micro usb port did not work, however the sound/video did but the battery would get drained fast I could watch 1 full movie with about 30% battery left so I had to charge after that.
I ordered the HTC media link now and will try how that works, from what I have heard and seen it seems 10x better than the MHL adapter and it should since it costs quite a bit more than the MHL adapter

Battery life

So I would have gotten a Note Pro or a Tab Pro, but those reviews were generally pretty pessimistic about the battery life. The reviews for the new Tab S are a lot more positive about battery. What explains the difference? Just curious.

So, I can answer this at least in reference to the 8.4.
The battery capacity is slightly larger 4900mAh vs 4800mAh. But beyond this, it really depends on how the tablet is used. In amoled screens, pixels are individually lit. That means no power is required for black pixels because the individual LEDs are just off. In the case of the Tab Pro's screen, the LCD has a backlight that covers the entire screen, so basically the same amount of illumination is given to dark pixels as light, which is the reason why the contrast is reduced vs the amoled screen.
A (simplification of a) trade-off here is that at a certain ratio of light to dark pixels, it uses more energy to power an amoled screen vs a backlit LCD at the same brightness. So generally, if you're watching a dark movie using apps with dark backgrounds energy consumption will be lower. The opposite can be said about viewing images with bright vibrant colors. It's really hard to gauge what the net gain or loss is under a normal use scenario, but it seems that we may be able to presume that it is at least slightly more efficient based upon the initial reviews.

I've read some reviews that indicate 12+ hours of use at 50% brightness. My guess is that these things used in the real world would get battery life somewhere between 7 and 9 hours. I have an older Samsung Galaxy Tab 7.7 (AMOLED) and that's roughly what I get.

Wow. Thanks for the explanation. One of the reviews I read where there was a divergent test (web surfing rundown vs video rundown) and the Tab S did *way* better on the video rundown .

So far: 10.5 model, 32GB, initial charge, low brightness (25% or less), lots of video streaming, video downloading, lots of screen use, lots of surfing, lots of wi-fi use, I'm at 8 hours use time with 33% charge remaining.
We would all like infinite battery life but in "real world use", I think this is pretty decent battery life.

How can you enjoy that at 25% brightness. That kind of defeats the purpose of having a phenomenal display.

I enjoy it easily. A phenomenal display does not require "flame thrower brightness". Quite the opposite. I wasn't outside in the blazing sun. Additionally, I've never used monitors, TVs, tablets or phone at 100% or even 50% brightness -- it's just too bright for me, so why waste the battery power? I think people have become acclimated to jacking up the brightness because of poor LCD display black levels and viewing angles. Manufacturers like to cheat with contrast ratios by boosting the backlight because low black levels are so much more difficult and expensive to produce.

Lol 25% brightness? Seriously? Do you use a flashlight?
I'm running about 80% brightness and have had the tablet off battery for about 3 1/2 hours and actually using it for about 2 1/2 hours. I'm now at 48% battery. So real world use at realistic brightness? 6 to 7 hours.
* Caveat. I am confident this will improve a bit as the battery gets broken in.

So far the battery life is bad at best. Third day using this and it's not getting better. 2 hours and 29 minutes of use this morning and I'm down 29%. That's putrid. Normal Web browsing and the tapatalk app. I need root in the worst way. The lag is also pretty bad. I'm not even using touch wiz (Google Now Launcher). If it wasn't for this beautiful screen and weight of this tablet it would be going back.

I have found that turning the wifi to "only when plugged in" doubles my battery time. I just traded in the 8.4 pro for the 10.5 S and discovered this fact while using the Pro for the last week. I just picked up my 10.5 S tab and have been good battery time since turning the wifi off all the time.

Are you talking about the"keep WiFi on during sleep" setting? I'll try that but it seems like a bug then as that should only apply when charging in sleep.

Battery life is exactly what people should expect with an AMOLED display. They're poor on whites and excellent on blacks. Whether that's good or bad depends on what ratio of each people view.

Face it guys. These devices never get anywhere near advertised battery life.

Sounds like you have a bad egg. I'm using Nova Launcher too. And it blazing fast! No lag at all. Maybe a small hiccup when downloading files but barely noticeable. Your batter drain is alarming. I'd send yours back cuz that's OBVIOUSLY not normal..

Not when you're 80% brightness. The most I use indoors in 30%. I'll crank it up to show off, or when I'm outdoors.

That's true. But why did all the reviews say it was excellent. Not one bad review. Crazy.

I've found the drain to be about 10% per hour on my 8.4". I'm usually using it set to 25% brightness, which seems to be ideal for any conditions in which you are out of sunlight. The people who are using it at brightness levels of over 50% are the ones who need their eyes checked.

I agree on this one, I have the brightness set at 50 % and the display is so bright inside buildings that there is no need to go higher. I don't know what everyone is complaining about, but my battery drain is about 8 - 10 % per hr, normal use, web browsing, video, facebook etc.. I have 8.4 model.

I just like a super bright screen. Can't imagine running this at 25% brightness. What a waste.

Waste of what? If anything above 25% is too bright for someone (eyestrain, preference) then the waste would be increased battery drain.
If burn-in is any cause for concern, keeping the brightness low for the first 50 or so hours of use may reduce the chances of burn-in for the life of the tablet.
More is not necessarily better.

Samsung Galaxy S5 - Grayscale Battery Savings True or False?

Below is a link to a write up I did testing Color vs Grayscale screen. I tried to do it pretty scientifically. I hope some people find it useful. Please let us know the results if you do this test yourself, or any other tests using Samsung AMOLED.
http://seperohacker.blogspot.com/2014/09/samsung-galaxy-s5-grayscale-test.html
The result summary:
The test revealed that Grayscale measured very slightly better than Color. After 90 minutes of testing each at 100% brightness- Color showed a battery decrease of 9%, and Grayscale showed a battery decrease of 8%.

Black works better for amoled screens. I've seen lots of write-ups on this topic since my sgs3 days

Battery benchmarked, good results

Let's wait to see how the Snapdragon 805 performs, hope it will be even better.
"With all these tests, we could say that those planning to buy the Samsung Galaxy Note 4 with its monster 3,220mAh battery should be relatively pleased. The Note 4 lasted almost 12 hours on the video test at 100% brightness, a bit more when brightness was lowered to standard viewing settings. This places the new model in the top 5 devices with longest battery life in this test. The Note 4 also lasted 7 hours on the WiFi test at max brightness, and a full 1.5 hours longer on standard brightness – again placing the device in the top tier of devices that last longer on this test. On the graphics render loop, the Note 4 lasted 3 and a half hours – this drops the Note 4 to the middle of the pack or better, still a relatively good place for it to be"

Actually the "standard" brightness should be lower, about 150 cd/m2 or even lower when viewing indoor.
And when watching video I think no way I do not turn on power save (even with web browsing), so the result still can be different.

Regarding battery, the results will always be different because we all spend different amounts of time on different tasks. This kind of tests is just to give us an idea and compare with other devices doing the same. ☺

Battery life thread

I've got both the S20 ultra, with its 5k mah battery and the p40 pro with its 4.2k battery. I'm getting better battery life from the p40 pro ? so far anyway. Latest 114 update is on the p40 pro
Please post your consumption
With 50% left this ain't bad at all. I am using 60gz though, I see no real benefit of 90hz. So minor to my eyes. No Google installed either

It looks as though not having you're screen on 90hz makes a large difference.
On average over 21h usage I'm getting 7 to 8hours of SOT but then the battery will be about 10% my screen is set to 90hz spo I must use a lot of power.
That's one hell of a mobile phone order :good: how is the Samsung ultra which do you prefer? How is the build quality between the two which feels better?

Feel is subjective. Both in cases so can't really feel. P40 being smaller is more comfortable.
That snapdragon gpu is a beast. And that phone never gets above 35c whether fast charging or games. P40 pro is about 3 to 5 degrees celcius hotter generally.
They both play any game easily. When it comes to difficult emulator games the snapdragon is a few frames better
The p40 pro is more efficient even with smaller battery, I'll try 90hz tomorrow
S20 ultra looks more premium, just. Has better sounding speakers too but the p40 pro is louder
The p40 pro has a better camera. Not by much, generally better zoomed in pics. Much better low light and better focus ?
Leaning towards keeping the p40 pro

Samsung have had a focus problem on there phones since 9 series devices...
I'm not sure whether to send the p40 back and keep the note 10+ or not??
I do prefer emui over Samsung ui

You can see the difference in the power drain between 90 hz and 60hz on the attached photo. 60hz being the bottom power drain.
I have also noticed that you can turn off 5G up in the quick settings which might save some power? No point having it turned on when hardly anywhere has 5G

That does look substantial. I'm checking this myself. I prefer EMUI too can't stand Samsungs new battery info layout

Started another battery cycle with the screen set to 60hz and 5G off. And after 1 hour of usage and 1hr of SOT I'm at 98%!
Very interested to see the results tomorrow evening.

if your ultra is exynos its not suprising you get bad battery life out of the s20

well that is more bad then cause the snapdragon is the best one with regards to s20 ultra but i know their optimization is really not good maybe thats why you get bad sot

It's not bad with the snapdragon. It's good actually. It's just better with the p40 pro

Which one are you sticking with the s20 or the Huawei?

Yes I believe snapdragon still better for gaming. Only problem is our area only have the exynos varient

My Mate 20 Pro with 4200 mAh was easily the best smartphone that I owned in terms of battery life. I also used to have a Honor 8 Pro for a while and it had good battery life as well. So I'm not surprised that the P40 Pro's battery life is great. Maybe it's because of Huawei's "aggressive RAM management", not sure.

I don't think the p40pro is in the same league as the mate 20 Pro that things battery was epic.

I have the p40 pro. Everytime it reaches 13%, i know it'll run out of battery soon, less than 5 minutes. Is this happening to you too? Cause it's really frustrating. My old p30 pro never did this...

I'm in a similar if lower specced (but only just) kinda of boat currently using the Samsung note 10 lite and I just got the P40 non pro this week.
Battery life is definitely way better on the P40. The Samsung I'm using very lightly right now (mainly yt music and regular phone calls) and it doesn't last that much longer than the P40 which is in use almost all ways. If not it's probably a hot-spot or always on display or both.
Turning off 5g definetley makes a difference. I'm in London so I have 5g almost everywhere but even with 5g disabled and lower battery usage I'm seeing really fast connection speed (over 700B/s)
Really want to make a test of the ultra pow energy mode. My phone thinks it can achieve ove 60 hours run time from 69% battery charge. If that's really possible just wow.
I haven't tested a lot of games yet but I have fired up xplane. It ran perfectly looked gorgeous in this tiny pixel dense screen and hardly used the battery faster than browsing. Got some emulators too they run like honey and the phone doesn't even get hot at all so far in the emulators I've tried.
