Bad battery life from professional reviewers

I am sick of hearing about how bad the battery life is on the Gear.
My Gear have great battery life, charge it every two days but yesterday.
The Google Smart watch is coming and it has much better battery life that the Gear's 12 hours??? !!!
Who can only get 12 hours on the Gear, and what do you do to burn the battery that quick?

Mine also lasts 2-3 days.. I'm connected to the note 2 if that makes a difference.

Should make no difference at all.

thats because most reviewers dont know what they are talking about

My battery life is great. 3 to 4 days moderate use. And worse comes to worse wack it on the charger while i get ready for work and I have a days worth of battery.

I have a feeling they had pre-release versions which may have had worse battery life. Shame!

Yes, with more recent gear manager updates, I get around 3 days+

Mine lasts 3-4 days.
But I am only using it during the work day.

At the end of the day I have 85% left everyday. I think its biased reviews. I'm sure if the apple watch had a 6 hour battery they would says its genious and revolutionary.

As a longtime 'professional' reviewer for over a decade (for the high fidelity audio industry), the non-rooted watch gives about 2 to 3 days battery life. Also, I don't recall seeing any reviews where they sideloaded apps, which makes the watch even more useful :good:
Frankly, don't trust all reviewers. :cyclops:

hahaha .... :laugh: ... they (those reviewers said about bad battery life) have already decided just on the number of xxx mAh. (once they see it.). :laugh: :laugh: :laugh:
I NEVER TRUST ... I TRUST MYSELF ON WHAT I HAVE DECIDED and TRIED ON MY OWN.

My battery life is 3 or 4 days. .. depending of use .
I think it depends of 'home screen ' . With watch styler, if my watch face is 'white' battery life can be 2 or 3 days. But with a standard watch face (black) battery life is 3 or 4 days...
If bluetooth is always turn on, the other battery's drain can only be screen... and it depends of the number of notifications you receive every days ! (And number you look at your watch daily )

Yes I agree with you on that I get 2 to 3 days of battery life heavy usage brightness at 4 and timeout at 15

Yes my Gear had pretty decent battery life, 2-3 days. Works out great just plug it in when I go to bed.

I have been using my gear on an S4 with android 4.2.2. Battery was usually about 50% at bedtime. I updated to the android 4.3 yesterday which gave me full capabilities of the Gear. Today after 8 hours of pretty heavy use (lots of email) I am at 90%. 4.3 does a much better job of handling BT connections, not just on the Gear but my other BT devices.
This is my 4th smartwatch (Sony MN800, Sony MN2SW, Pebble). The Sony MN2 was pretty decent, touchscreen/color but its battery life was terrible, had trouble making it through the whole day. Pebble had great battery life, constant on screen, but having to use buttons and no color was tough for me after having a touch color screen. Gear is definately heading in the right direction for me. Now that the battery life is can last 2+ days I am even more pleased with my decision to dive in. I turn the screen brightness to +2 which is extremely bright for indoor use.:good:

Yep, agreed.
My battery life is more than I can hope for with this thing.
I'm on day 2 and still have 61 percent battery life left.
I have screen brightness on 1 (which seems perfectly viewable for me) and time out for 7 seconds.
I can go 4 days easy with my current settings.

While I agree the battery life is a bit better than the reviews suggested, I'm surprised so many of you are getting 3-4 days worth. I use mine very lightly... it's stock, I don't have hardly any apps loaded on it, I'm currently just using it to occasionally see the time, and get txt/call/email notifications. I have the most battery efficient watch face (the black one with orange hands and only four markers), brightness on 4, timeout on 10s, using the latest gear manager on a stock Note 3. After 48hrs, I'm below 30% battery. The only excess usage I get is from the auto-wake... I do notice it coming on sometimes while I'm driving, or at the gym. Other than that, I really don't see how I could use it any less to get more life out of it (other than not using it at all). Once the software gets updated to make it a little more useful, I would expect battery life to get worse.
I'm not complaining, 2 days is acceptable to me, I just would have expected my usage patterns to put me at the long end of battery life relative to other users, rather than the short end.

I agree the reviewers had very bad results or bias, But at the same time I wish I knew how you guys were getting your results. Today was a light day, got maybe 20-30 texts and 5-10 emails. Didn't make any calls or respond to any texts with S-voice. I did just realize I had reset it recently so the brightness was at 4 with a 10 second time out. I normally run brightness at 2 and timeout at 7 to try to save the battery. I also use strong vibration and have the digital clock/weather watch face with a black background. I am at 82% after 12 hours, which again I don't think is bad. That would net me 2-3 days, but again that was what I consider very light usage. With heavy usage I doubt it would make it through the day.
I'm not complaining because I am ok with charging it every night, so long as it makes it through the day I am ok with it. I would just be happier if I knew I could get 2+ days with medium usage at least, including bright screen and all that jazz.
Also, side tracking I know, but what apps have you guys side loaded that you have found useful?

I have brightness at max and use it VERY heavily. I work as a mobile computer tech and all my calls are taken on it, I use svoice to make calls, I use svoice to reply to SMS and I'm always playing with it. The lowest battery at the end of a day (by which I mean 7:00am until midnight) was 38%.
I really cant fathom how it would be possible to deplete the battery in just 12 hours.

my use today :
I read 15 sms, 10 mail , take 3 pics and call with my father 15 min with gear speak phone (and the other 15 min with the phone.)
blue tooth connected permanently.
Number of auto wake : ?? A lot !!
Time Out : 15s
last complete charge : this night ( disconnect at 8 am.)
Now I read 1:28 am.
Battery level : 61%
it's all rights !!!

Moto X and Pebble

I am thinking about getting one of the Pebble Watches and i was curious if anybody here has one, or knows somebody with one. I'm concerned that the Bluetooth connection is going to kill the battery life on my X. Anybody with experience using these two devices together and what has been your experience with battery life.

Yup, I have both. Battery drain is going to be dependant on how many notifications you get a day. That being said, I would be considered an average user I would say, with work and personal email addresses, txt and BBM. I get about 200 notifications a day and the battery drain is about 8 - 10% higher than normal.
I could not get through a full day on a charge. I typically charge it up during lunch hour or so, and can make it to about 10 PM.

I have both and really notice very little additional drain on my phone. I can go a full day without recharging and generally end up with about 30% left around 10pm. I would consider my use around average with 1.5 on screen hours by the end of the day. I am running a custom ROM though that I think has the base kernel on it though.
I would strongly suggest getting a Pebble. If I was in the market for getting one now, I would spring for one of the new metal ones.

I also have both and haven't noticed any noticeable drain on battery life. The Pebble is fantastic, by the way.

how much of battery drain do you get on the pebble watch itself per day. I was just wondering because I relly like the look of the new pebble steel ad I am considering getting one when the prices get reduced some.
Thanks

I can go about a week before I need to charge my Pebble. The battery life can float a day in either direction based on how many notifications I get. It is also dependent on how often I flick my wrist to engage the back light (one of my favorite features actually). You get a low battery notification on the watch, no percentages or anything though, that tells you to charge in the next 24 hours. I find the battery life perfectly acceptable especially compared to the Samsung Gear watch that has to be charged daily.

Thanks for the feedback guys. I bought one at Best Buy on Friday night. So far, so good. I'm seeing probably about a 20% drain. It's 3pm and my phone has been off power since about 7am and i have 53% left. My usage today on my phone, outside of Pebble has only been sending a handful of text messages.
Any suggestions on Pebble apps or watch faces?

I use Glance, https://play.google.com/store/apps/details?id=uk.co.finebyte.pebbleglance , for my watch face. It's not the most elegant but it gives me all the data I want in the format I like. I also implement Notifier, https://play.google.com/store/apps/details?id=com.dattasmoon.pebble.plugin&hl=en, for non-basic notifications. There's a ton of development out there though.

Heavy use endurance

Playing Candy Crush for 22 hours straight can take its toll on your battery (and your marriage). Rate this thread to express how the LG V20's battery performs under heavy use. A higher rating indicates that it lasts a long time even when playing games, streaming video and audio, and doing other CPU-intensive activities.
Then, drop a comment if you have anything to add!

3 hours and 8-12 minutes of 1440p video at full brightness, loud speaker, wifi on, and screen recorder running (although the file messed up so i cant post it).

bad

Battle Bay: Less than 2 hours!

I can honestly say that it really depends on what I am doing. For example if I am digging around on the WOW companion Application or Yahoo's Fantasy Sports Application, the whole phone will get heated up and the battery starts taking a nosedive. If I'm not doing anything with my phone it can go 15 hours straight without losing a single percent. If I am just watching YouTube or something along those lines at 1080 or lower it seems to still go down, but not nearly as quickly as the (possibly poorly - from a power consumption view - designed) apps mentioned before.

As far as I'm concerned the removable battery negates any battery performance complaints. Out of power? Pop in a new battery, and you're 100% in a few minutes, back to endure more "heavy use"... How can any other modern flagship begin to compare?! (not to mention a year down the line, when I can just buy a fresh battery to mitigate deteriorating capacity, while the crowd has to buy a brand new iphone/s9/m10)

I've been playing Sky Force Reloaded a lot the past week. I had to be next to the power charger. I haven't bought a spare/secondary battery yet. I carry around a usb battery and a short cable when I need too...

Installed some more apps and games, and talk about nosedive. From the time I leave the house at 7AM to about 12 noon, the battery drops down to 15%(battery warning). I have to charge it then. I have to charge it again when I leave the office, which is around 5PM. Battery level varies at that time. Then charge again before bed. I still haven't rooted my phone. Phone temperature remains about 80F to about 108F(heavy use while charging) at times. LinkedIn, xfinity, Groupon, Weather, Waze, etc. Battery drainers! I've about almost had it. I miss root, and miss the ability to freeze apps. I will have to root this LG V20 sooner or later...

I usually can keep my phone charges, in the car, desk, night stand. Today we where doing Hurricane prep listening to Spotify while working, watching YouTube while in the car driving from place to place. Had to set the screen to auto brightness to deal with the BRIGHT sunlight outdoors. After about 3.5 to 4 hours of use and 1 hour and 30 minuts of screen on time I was down to about 38% battery. I had to drive home and grab my power bank. I've only had my V20 for 2 months.
Not impressed!

Stock AT&T H910.
Just got my new Note 8 and yesterday I had 7 hours and 44 minutes of on time and 3 hours and 10 minutes of screen on time and was at 50% battery. That far better than my 2 to 3 month old V20.

It is a bit of a nuisance especially at first. I've learned to adjust my grip so I grab the phone a little higher up than I used to and this makes the fingerprint scanner easier to reach. Since the Note 8 as narrower than traditional phones due to the new display format going it higher is easier while still being able to hold the device securely.
Still not ideal but manageable and definitely not something that would keep me from buying the Note 8.
I'm also using the facial recognition feature in conjunction with the fingerprint scanner. It's not something I thought I'd be into, but it works really well even in conditions I assumed it would not, like low light and slightly of angle.. So if I don't feel like doing for the fingerprint scanner I can just got the power button while holding the Note 8 and it will unlock.
Note I do have slightly bigger hands than most.

I disagree. If I have to change the battery every four hours of heavy (not even that heavy), somethings terribly wrong. If it was just one battery swap, maybe I could agree but I'd need at least 3 or 4. Luckily I'm usually able to keep my batter topped off most regular days. Removable batteries is no excuse to have horrid battery life.

Neat thing about a removable battery: it lets you swap out for a bigger unit.
I have a 6700 mAh battery in my H918, and haven't plugged in before bedtime in months. I can stream hours of video with full brightness and no thought for power. And that's the small option, the ZeroLemon unit is 10000 mAh, I just don't need that much.
In the end, the phone is only as smart as the user. I guess we can lead a horse to water.... but we can't keep removable batteries on the market if the people are too limited to use them :crying:

6700mAh battery, no thanks. I'm content with a normal size battery that can get me normal size battery life like other devices. Then a spare on those rear occasions I need it. The V20 should be commended for having a removable batter (probably the last higher end smart phone to offer one), but not it's battery performance.
I'm smart enough to want normal battery life out of a normal size battery, removable or not. :crying:

I voted "bad" because real world battery life is actually inferior to the 2012 Samsung Galaxy Note II it replaces. Naturally in lab tests the V20 massively outlasts the 2012 vintage Note II but I don't live in a lab. It's the only aspect of the phone that isn't a considerable improvement. I knew that if I listen to streams using the high quality audio with decent earphones the V20 isn't going to last like a modern Samsung or iPhone, or even Xiaomi, but I am a little surprised how it's not better. The replaceable battery is a necessity, not a luxury. Anyway it is mitigated by Quick Charge and the fact that the device seems to me to be just about beyond criticism in every other meaningful way.

Yes the battery life sucks stock but they do make a 4200mah now that fits in stock place no issues. I bought it and I get 6hours 44 minutes screen on. Much much better then the stock 3200 with no added size as it fits in stock compartment and cover.
Recommend to any V20 user.

Galaxy Watch 3 Alternatives

Because of the shortened battery life, has anyone used any alternative watches to the gw3 that are comparable and have mostly the same features (calls, texting, emails, etc.) in the US for android?

Anyone?

No alternative in the Smartwatch World Only alternative with better battery life in the Tracker World but 0 function
Maybe Fitbit Versa 3 & Sense. A little Smart a full tracker and no bad battery life

Samsung Galaxy Watches are the only Android e-sim standalone for USA carriers with LTE 4g bands....

Just seeing if there are any bluetooth alternatives out there. I just got a gw3 yesterday hoping it would be better than the og gw and not disconnect all the time but 24 hours later and the watch is down to 43%. Just not gonna cut it when I am not using it much. I like the watch ecosystem but this battery is just not good.

I got my GW3 the first day it was available at my local store and have just established a routine where every other evening I put it on the charger for a couple hours then put it back on before I go to bed. Only times I have varied is when I switched to watch faces that were battery killers.

Yeah, I charge mine every day for 1-2 hours depending on my use. I wish it charged a lot faster and then charging every day wouldn't be a problem.

I got the GW3 LTE direct from Samsung and I easily get 48-52 hrs on a charge: WiFi set to auto, LTE set to auto (I'm on what's left of Sprint), no AOD on, +several notifications. So not sure why you're not getting good battery life. I have noticed anywhere from 1-1.3% discharge per hour. I use it with my Samsung Note 20 5G (standard)

I use an active 2 and a GW3, switch between the two. Since they both use the same OS, same app. It's a seamless switch, kind of like wearing the same watch all the time. I don't need to worry about battery life cause I'll always have 1 fully charged.

I have the Samsung Gear S2. It has 250 mAh battery life and it can work for 2–3 days depending upon the usage.

Question Battery life not lasting a day....

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.

Try disabling all power management.
In Developer options>standby apps all buckets should show as active otherwise power management is running.
Google Play Services, Backup Transport and Framework are known hogs.
Disable all the bloatware, turn off auto sync for gmail, turn off all feedback.
You'll need to sort it out and optimize it. Took me months to get my 10+ sorted out. Fortunately it's running on Pie so I had more diagnostic options.
Returning is a thought as 5G may have been poorly implemented and another source of power drain. I think everything after the 10+ 4G both hardware and OS are train wrecks... I see very little incentive to "upgrade".

Maybe post screenshots that aren't below 5 kilobytes. Lol. I'm guessing you have an Exynos variant?

It's too early to judge the battery life, also accu battery app is not good at all, it's not accurate as your own phone's batterymeter.
Also, you need a week or so to make sure the phone get optimised according to your usage.
Does your phone have Exynos 2100 or Snapdragon 888?

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.

I suggest doing a factory reset before you think about sending the phone back. Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Reloads -never- find the root cause and many times even if the problem is "fixed" it eventually returns.
Exceptions; old loads, software induced bootloops, viruses, and major firmware updates.
Expect issues with the 5G devices from poor hardware implementation. No fix for this.

I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

How much with screen off is it sucking down?
If more than 1% @ hr with AOD on it's probably Google and cloud crap running in the background.
You can optimize it to improve performance.
It's easier to do this with Pie though; Q and 11 take away critical tools and use scoped storage which wastes cpu cycles.
Get Karma Firewall and a package disabler like this one;

Regardless of the model or OS version most carrier phones will need to be optimized for good battery life and optimum performance.
My 10+ was a hot running bandwidth hungry hog until I toned it down. Today it's hard to believe it's that same machine.

You are right, I agree with all you said. It is kinda sad though, as for instance, my ex Asus Zenfone 7 Pro had an absolutely mindblowing battery life, without any tweaks. I just used it. With all the hype around the S21 Ultra, I believed it again. The only Samsung I used with good battery life was S20 FE 5G.
Will give it a go with what you say though, thanks.

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.

Well, i believe what you are saying about battery life, but what i have seen so far is promising, i mean when S21 Ultra with Exynos 2100 beats iphone 11 Pro Max and 12 Pro Max, i guess that's a good sign!! But for sure, we use our phones in different way than each others because maybe you use it with 4G/5G enabled almost all the time while these tests are just using Wifi and maybe without any SIM card which means the battery consumption will be minimum at this part.
I have S20 Ultra with Snapdragon 865, i get like an average of 6 hours SoT and if S21 Ultra Exynos gives me the same SoT, i'll be happy!!

SOT is not everything...we travel, we move, you cant accept a phone that gives you 12 hours of standby in total. This is bs and useless, you cant rely on such a phone.

My AT&T 10+ was not real bad (or good) the first few days. After enabling power management it went to hell.
Eventually I disabled all power management and one by one tracked down the hogs.
Because of dependencies simply disabling and/or turning off say Google Transport and Google Framework isn't enough, firewall blocking Google Play Services* then clearing data on all 3 periodically finally stopped this hog dead in its tracks. These will run in the background when the screen is off stealing power for nothing. Sometimes the Google apks are misreported as other Google apks presumably because of the interlinking dependencies.
Try using Galaxy Labs Battery Tracker.
Developer options>running apks/cache can also yield clues. With an unrooted phone there's some serious game playing to track this garbage down.
Anything app that's cloud or carrier is bad... lol.
Disable all feedback and syncing except for texting; manually sync gmail.
*needs to be unblocked occasionally for gmail to download and for Playstore (another apk you should disable/firewall block when not using).

Try disabling 5G if you are not using it, for some ppl SmartThings drain a lot of battery but you should see that app in log. Can't wait to get mine, also E2100 and coming from Note 8. Was rly looking to have a 2 day phone.

That's a thought that's worth a try.
From what I've read even disabling 5G doesn't completely stop it's parasitic battery drain.
Maybe the latest generation chipsets are better but early 5G was poorly implemented giving a marginal speed increase on most phones of 20% when available.

Is this on the snapdragon or exynos variant?

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies. I can tune it so it works for two weeks on the battery or I can actually use the thing and get 2-3 days. I choose 2-3 days and have stuff I want to use. I'd rather my phone be reactive and tell me when I've got emails, etc than to get super long battery life and basically have an inert brick in my pocket. I have a cellphone so I can use it for stuff. If that makes the battery not last long, oh well. If it can get 5-7 hours of screen time while also lasting through the day, great.

My 10+ draws roughly 1%@hr* with AOD on.
SOT draw varies between 9-12%@hr
Roughly 10%@hr watching vids on Samsung internet with surfing on Brave being the highest usage.
I consider it fairly optimized at this point.
*4300 mAh battery with little degradation.
No 5G running on Pie so not scoped storage either.
Figures are from a charge range of between roughly 40-65% as I rarely charged beyond 70% or discharge deeper than 30%.
Actual usage be more if I had started at 100% because of the power density difference through the power range ie 1% at 20 is far less watts than 1% at 100%.
A/V=watts. Less voltage means less overall mAh per % plus the additional losses due to voltage stepup power conversionas you dip towards 30% The closer to 100%, the higher the voltage with more available mAhs per battery% as well as less stepup voltage power converter losses.
A phone's wattage and V+'are constant so as the battery voltage decreases it draws more current ie mAhs.

You are also right, but , when you used something that does both keeping you up to date, and having a brilliant battery life, then it becomes disappointing when you change it for one that doesnt.
