Battery Life Problems

How's everyone's battery life? I get down to about 5% by the end of the night with light to moderate use and standby time seems to be pretty terrible (5% drain an hour or so).
I checked in the battery info and it shows Android OS at the top with 66% use and when I click on that, it shows Keep awake at 3 hours and 49 minutes.
Anyone else having this problem? I did a full wipe and that didn't fix anything. I'm also running the latest update.

I can usually last a day with moderate to heavy use. Haven't found it to be any shorter than that so far. Try turning on the processor eco mode

I wake up at about 7:00a.m. and go to sleep at around 12:00a.m. And I usually go to bed with about 30% and this is with moderate use, with full brightness and eco mode off.

My battery life is pretty atrocious as well compared to my Evo LTE.
I'm at 40% at the moment after 7.5 hours. That's mostly wifi and without 4G. Have tried keeping the screen at 40-50% brightness, eco mode on, quad control, on, etc.
Even tried cycling it a few times by letting it run all the way down and charging until 100% with phone off and it's there's been no improvement.

My unit idles pretty well actually. About 1% (or less?) per hour. No complaints here.

I have been surprised at the battery life of this phone. I was annoyed after I bought it because I didn't realize it didn't have a removable battery and I typically buy extra batteries. I gave it a try though and yesterday I used it moderately while at work for 12 hours, used it for streaming audio on the way home, and after a total of about 14 hours without charging it was only down to 70%. Eco mode was on, and screen set to 67%. Periods were with 3g, 4g, low signal, and wifi.

Dont know why you would have such bad battery life, i used my phone all day yesterday from 530am til i went to bed last night at 1115pm only 30% discharge at that point , i dl a rom on it for my gs3 when i was going to sleep 789mb and woke up this am to 36% bat left. I am truly pleased with the performance so far.
I am not a light user either and use it to play need for speed , I haven't even put it in eco mode yet.

Honestly no complaints so far. I've been toying with it for fifteen minutes after ten minutes of music play and it only now went from a hundred percent to ninety nine. On my 3d it would be down ten to fifteen percent by now.

I haven't had any issues with the battery either. After a decent amount of web browsing, a few calls and a ton of texts, some angry birds star wars and final fantasy 3, I still have 70% left. Also have wifi, gps on constantly, 68% brightness on display and no eco mode.

What are you guys getting for screen time?
Sent from my SPH-L900 using xda premium

I've had almost 3 hrs of screen time and 12 hrs on a charge and only been down to 30% (with some Pandora streaming in there too). I normally get done with work and playing some on my phone and am still above 70% after 9 hrs. I can't complain about battery life in any way!

What percent of the battery usage is "Android OS" for you?

This morning I pulled her off the charger and browsed reddit for an hour with the screen at 63% and lost more than 20%.
I'm exchanging it and if the new one doesn't work any better I'm probably going to sell it and go back to the Evo.

Hard reset your phone and start over ,there is no reason you should return the device before trouble shooting
Sent from my LG-LS970 using xda app-developers app

Already tried HR, went ahead and did another one and ended up having to reset it two more times when the Play Store stopped working.
Now I'm running with a handful of apps, one email account and I'm not syncing to anything other than Gmail and I'm still down 17% in the last hour and a half, plus I'm getting force close errors just trying to access battery status.

Should i look into getting another Optimus G.?
This is without my work email being sync. And i get massive emails daily on that account

At the time this was done it was at about 40ish%.
At the moment I am at 25% after using my phone about 16 hours. Android OS is at 51%, screen at 19% with about 3 hours clocked in.

By this point I expect a minimum of twelve hours on the battery with at least two hours of screen on time. Im very happy with that if I use the screen for more than two hours it'll last about eight hours which is still good. This phone idles very well I expect it improve with future updates as well.
To the user who s getting a lot of fc's, I definitely don't get any and that's saying a lot for stock software from lg opposed to stock android. Don't install task killers of you have one

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy S7's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!

hi there. got my s7 few days ago and it sleeps like a baby hehe 1% lost in 6 hrs

I lost 10% of battery the past two nights. I have the always on feature turned on tho.

The mine 0,5% a hour
Inviato dal mio SM-G930F utilizzando Tapatalk

I typically lose about 4-5% overnight. Not bad, but not as good as a Nexus

I have a massive batterydrain in standby when I am connected to WiFi. When I'm on mobile data I have no batterydrain at all in standby
I don't have a clue why it is like this

I lose 18% over 8 hours. Maybe I'll try turning wifi off tonight. That said, battery life overall seems really good. No problems whatsoever getting through a full day on one charge.

Go to WiFi > more > keep WiFi on during sleep > off
More than likely your WiFi is causing the drain by the always scanning feature turned on

with heavy use, 2 days battery life without charging. and also its charging is pretty fast too

I loose 1% over a 7h night on plane mode.

Hey man,
I have the exynos version. Still on stock, i just used "package disabler pro" - as you do - to get rid of all the bloatwares and apps i don't use.
Oh, and i don't know if that's relevant, but i disabled the fast charge, in order not to preserve the - non switchable - battery, it still charges quite fast.
I've checked three times now, i was never below 99% when i woke up.
Hope it helps.

Yet this is. I just turn the phone back (with the screen hidden) so that the "always on" doesn't turn on.

I am having massive battery drain
My phone drops 20% in 2 hours on standby and I'm at my wits end trying to figure out why android os is taking 500mb of data a day

20% Over night absolutely not normal!
Have to recharge phone twice a day.
I am on stock and cannot apply root (this is company phone).
When I had Nexus 5, battery drain was not so horrible.

Here is a picture of my battery drain
From start I have WiFi on and then I turn WiFi off and the battery drain stops
Can't understand why WiFi is draining my battery like this ?

One more... Only till 15%

1hour left with 15%? Not so sure about that.

BTW, WLAN is active for position only. 4G all the time!
This time while traveling around in Dayligh. The other one before was indoors no moving!
Oh yeah, and No Video watching on this one.

One more, pretty similar result ^^

^^^^
Is Power Saving activated ?
If not , can you test the battery life using the power saving mode from 100% to 10% or lower ?
Thanks

looks like battery life is impressive. lurking here. might get this one next or wait for the next nexus

So yeah, here we go. Power save Mode activated all the time.
Meaning you can't use it Outdoor because the screen is way to dark.
And a lot of Web surfing indoors....

Lol wtf is this what u call great battery life? Its draining in 8hrs to get 5hrs sot lol

Mention your screen brightness level. Don't say auto it means nothing. If you do it in manual how high is set ?
Also always mention whether it was wifi only, data only or a mix of the two
In this graph i notice your 4g is a solid green line, that is lucky for you and rather difficult to get for most. A signal like that means very good sot especially since you can also control background apps from consuming data.
Take it this is 6.0.1 ?
seen pretty good sot with that build, like an hour more than earlier MM ones.

Nothing heavy but it got me through two working days with casual use, calls, some browsing. I'm totally content. From early morning till around next day 7pm.
This is good IMHO. Expected nothing more from a smartphone using constant syncing of Gmail office mail, fb, Twitter. Screen brightness kept appropriate for lighting, lowest readable generally in auto mode.
Power saver off, only on on screen shot because I reached 15%

One more Battery save Mode always online.
This time traveling around in a train while listening to Youtube music and browsing Tapatalk/Web via Chrome.
6h SoT

I just got the phone today and have played with only couple of hours so far. I played music for an hour and battery eaten was about 5%, which is pretty good IMO. I am impressed with this phone so far.

Power Saving does not kick on until 15% left. I had not used Power Saving at the time of screenshot. I'm not sure why App usage so low. Maybe cause screen and phone much higher in relation?
Sent from my HTC 10 using XDA-Developers mobile app

Well, I'm impressed. 2 days of battery life? Not with my usage habits but it got me through an entire day of no-compromise use which is excellent in my opinion.
My day started at 6am with the battery fully charged. I spent from 7am to 4pm on 4g networks with a good signal the majority of the time. I was on wifi all other times. I have Google Now enabled and location settings to battery saver mode. Auto-brightness is set to about 50% which works well for me.
I might actually be able to pull 2 days out of this phone over the weekend while I'm mostly on wifi!

Adguard excessive battery drain?

I'm having a hard time deciding if the HTC 10 has poor battery life or if Adguard is just beating the crap out of it.
The usage shows like 5% to 9% for Adguard but I'm getting barely get 3.5 hours screen on time. Which isn't bad per se but I keep hearing folks get over 4 consistently.
For example today with Adguard from 5 AM to around noon I ended up with 36% with medium use. I had just over 2 hours screen on time. Then I charged it at work to 100% and from about 1 PM to 9 PM I'm down to 25% with 3:02 SOT.
I will try to see how my battery is without Adguard but wanted to see if you guys are seeing the same thing?

Adguard will use battery as it is constantly having to run a VPN server in the background.
It will also show lots of data usage as its being passed through it.
A much better solution imo, if you don't want to root, is to use firefox and adguard or ublock as an extension. Much more efficient.

It seems abnormal that your active time and total time are the exact same. So maybe it's not adguard.

Perhaps it's because it's still learning my battery pattern. I literally just downloaded it today.

You should use AdGuard's built in battery monitor, any other app will count the battery usage of apps that are filtered by AdGuard and give you wrong results.

I think MM is good in general, but so far so good. I only lose 1 to 3% overnight.

I have plenty of battery drain overnight, mostly the Android system, Android OS and Google services.

I've had the phone for 2 days now and overnight battery drain is around 5%, but the real problem is that Android System takes up around 30% of my battery.

in 8h night (standby) i get 1-2% drain.
wifi, sync enabled.
if you get major drain, then its something on your setup causing it.
its always like that. (except something is broken on hardware side)

OxygenOS 3.5.1. - 1-2% battery drain;
OxygenOS 3.5.3. - 0% battery drain (in one scenario phone was left to [email protected]% (took off the charger and it drained 0% in 4 hour sleep period and in the other scenario the phone was left @53% to sleep and it drained 0% in 8 hour sleep period)
more info can be found here -> http://forum.xda-developers.com/oneplus-3t/how-to/battery-life-sd821-400mah-t3505786

My experience is that the phone is better than average for sleep drain, just ~1-2 % with stock kernel. With Tyranus kernel v12 by @mdalexca, I'm not seeing any drain overnight at all. Battery life on medium usage looks to be a few days at least. (Yeah, I'm a light user aside from my first week with a new phone where I nearly wear it out ;)

Using Nova Launcher ...experiencing battery drain 3~4% overnight (5-7 hours) with WiFi off. But during the day, WiFi on, not even touching phone and it goes down 10% in an hour and a half. Battery reports Android System as the culprit. Any suggestions guys?

Hows your deep sleep, working ok? Even if it shows Android system, it could be some app which isnt working correctly.

I got someone here with one plus 3 non t version (I got t, same problem like you) and is just flashed Chinese version of one plus 3 on his phone and zero drain but bare in mind the Chinese version doesn't got Google services at all , no play store and stuff , is saying is got more juice now , but I am just thinking you will need to install Google services for YouTube and stuff . Hmmm just saying Google battery hog .
For now I am waiting for developers to receive their phone . I just can't wait for many custom ROMs

using stock Oxygen with BT/Wifi on, 2 push accounts with 4-5% drain overnight

How do I check the deep sleep? I just went back to the shop and idk what they did but they said they ran a software check(?) And asked me to try the phone again for a day. Surprisingly overnight with wifi off only went down 1℅ (but this was on oneplus launcher) but then during the day it drained as fast as previous. But now the batt reports show first Android OS, Cell standby and then Android system....

I'm not sure is it possible to check it without the root, but if you are rooted, then BetterBatteryStats is quite handy: https://play.google.com/store/apps/details?id=com.asksven.betterbatterystats&hl=en

I have the MBA bug. I see a lot of people avoid it by staying on WiFi but I can't. Result is rapid battery drain.
I'm still getting reasonable battery though if I remember to toggle airplane mode. Device sleeps well enough. Almost perfect awake to screen on ratio.
