[Q] Battery drain and high Android OS usage?

Last week I got a Droid Ultra and am noticing my battery life is pretty bad. I'd heard the Ultras don't get great battery life to begin with but I think something else is going on with my setup. My Android OS usage is always by far the highest, dwarfing the screen percentage. This is my first smartphone so bear with me if this is normal or I'm doing something dumb. My usage seems to be pretty normal by these board's standards, 30min talk, 20-40 texts, wifi on, and couple hours of gaming. (slow week at work!) I have installed Watchdog and it is running on moderate, although I must admit I don't really know how to use it to its full capabilities. I have attached some screenshots below, any advice would be greatly appreciated.

I have a Mini with the same issue. Still haven't figured out what it is, even tried a factory reset. So you're not the only one.

Did you guys try disabling the bloatware and turn of Google location?if you're still on 4.2 you can use gsam battery monitor from play store. It gives detailed info on wakelocks and and what's keeping your CPU active.

I have tried to get rid of the bloatware but they don't seem to be removable. I can stop them but they just restart later. I have just turned off locations so we will see if that helps. Will the program you mentioned work with Kit Kat? I am using DU Battery Saver at the moment. Thanks for the advice.

Gsam Won't work on 4.4 unless you're rooted. So you can disable the bloatware easily. Go to app drawer long press on app you want to disable as if you were going to add it to the home screen. Drag it up and drop it on app info. You can disable it there. Some apostle it will ask if you want to revert back to stock. Select ok. Best part is you can't break anything this way! If you want to enable the apps go to settings....apps...and slide all the way over for list of disabled!

Bloatware has been gone for a while. I tried disabling location last night, but still have the same high OS usage today. Just installed GSam- on 4.4 but rooted- I'll post if it comes up with anything helpful.

S7 flat/Exynos Heating and extreme battery drain

hello guys, i hope you all are having a great day. so my problem is this : as soon as i got the phone, i rooted it ( obviously knox tripped but that doesn't matter to me) i flashed some customs roms, but i didn't like them because the phone was lagging and freezing randomly from time to time with the phone starting to heat in just 5 min or less and the battery life got crappy. Then i decided to flash a stock rom odin, but that didn't change a thing, since the phone still having having heating issues and extreme battery drain. oh yeah, and fast charging doesn't seem to be fast even though the fast charge activated. Help you guys

Try a factory reset, and do a clean setup (don't restore any apps).. Then just give it like 2 days (the battery usually drains faster the first couple of days).. This same thing happened to me when I got the phone out of the box, rooted it as well after a week because I don't care about knox or warranty, phone was heating and battery draining so fast, I did a factory reset and a clean setup, after 2 days of discharging the phone and charging it to 100%, the battery life got better and stabilized, the heat went away. Now I easily get about 6 hours of SOT with heavy usage (gaming and stuff), and the phone barely gets hot (it only gets hot when I play pokémon Go on 4G because it uses your GPS constantly). I have the exynos version as well.
Edit: Also try Package Disabler Pro (it's paid but it's worth it), it disables all samsung bloatware and some useless services that keep running in the background, it sure helped my phone feel a lot smoother and get even better battery life.

I'd avoid Titanium Backup, just start fresh.. I'm rooted mainly for adaway because I hate ads, I use xposed as well..

You can also go to Settings > Battery > Details and then select apps that you don't always use to 'always save power'. Your stats seem good to me.

I heard somewhere that when you root S7 it changes the CPU's governor and it starts to lag overheat etc.(only in snapdragon model)

He is using the Exynos version, which does not have this problem. Only the Qualcomm root method results in the cpu governor being changed to performance, causing battery drain and heat.

Galaxy S6 Not displaying correct battery.

I have had this issue for a while and have been switching roms in search for a solution. My phone is draining battery no matter what rom I am using, but when I instert the charger, the battery instantly jumps up about 15-40% depending on how low it is. Does anybody know what causes this and how to fix it.
SM-G920i
Both Xtrestolite Deodex 6.0.1 and Xtralite Deodex 6.0.1
Pretty sure both roms use Arter 97 kernel.
Any help would be appreciated

Did you try to recalibrate it? Also, you should use Greenify to help you reduce battery drain while phone is not being used.

Here is a good guide which shows you how to do it. It's helped me, so hopefully it will help you as well!

Re-calibrate your battery,there are a few on the play store i used it each time i install a new rom (not needed for updates really). They do require root though. Also samsung introduce a feature which when your battery drain there willing be atleast 10% of battery remaining even though the phone shut down. This is an emergency feature and allows you to send or make a call with the last 10%

Nougat Battery Drain

Android System is draining my battery and is keeping my device awake for more than 2 hours. Is anyone on Nougat suffering from this? I didn't have this high drain on Marshmallow, not sure what's causing this. All help, suggestions, and opinions welcome. Thanks in advance.

I am on Nougat 7.0, stock. Even after doing all the typical battery saving tweaks, I found that using the Google App and Google Play Services were consistently the highest battery drainers. Was getting 2-3% battery drain per hour, with minimal or idle use. For the Google App, I ultimately had to stop using and disable Google Now Cards to eliminate that app's drain as nothing else worked. Still working on the drain on Google Play Services as that one still shows up but not as high as before, but am now getting close to 1% drain per hour on idle use.

my phone had no facebook, messenger barely go to google play, not setup google now. using nova launcher. all I used is twitter, google+, instagram, photo (backup), SAO game, and others living app. turn on GPS on high used too. battery live until night.

Are you guys rooted?

I used the Boost app that was introduced in the update, kills all processes you want it to with the smart feature, but has a weird side effect of being unable to download anything when it's in the background, just gotta hold the app open until it's done downloading. Battery life is fine for me, since using this.

Yes I am root. Boost app really to frozen the apps when phone off. but message and info still got intouch

My Sprint HTC One A9 phone is rooted, S-off, unlocked, flashed with TWRP 3.0.2-0 am on 6.0.1 and I am experiencing the same battery drain issue. I have tried multiple battery conditioners with no affect upon the battery life. It still drops very quickly and the phone will power off at about 25 - 30% battery left on the phone. Boot into TWRP and find the battery level states at 37 - 45%. Let the phone sit on TWRP screen for hours and it never powers off.
I cannot figure this out and am about to wipe my phone and start all over again.

OP6 Always Awake, Poor Battery Life

Hey guys,
I bought OP6 8/128 version and first, the battery life was ok, I was getting 4-5 hours of sot. Now, I see that battery is discharging in constant rate and something is keeping my phone awake all the time. Firstly I thought it was Instagram when it helped when I force stopped it. Now I'm lost 20 percent overnight and battery stats show, that all the time my device was awake. Cannot see anything suspicious through gsam or better battery stats as I believe the put it under android system. Help anyone?

Did you already do a reboot?

From personal experience, i found that updating OTA was the culprit. To get around this, download the full update from Oneplus and update that way.
Ever since i started doing this, I have not had the battery drain issues i used to have. Also, wipe cache before booting phone after update.

So I should try to do fresh install from OnePlus site? Awake time drops when I clear recent apps, so I believe this is either Instagram or Facebook doing this. Really weird. Even without awake time shown in graph, I got 35% drain in 1h sot and 11h standby, this shouldn't be normal, right?
It's crazy, because I used to have a good battery life

for testing, can you uninstall Instagram and Facebook for 1 day and see how your battery life changes.

I can tell you right now Instagram has a prefetch service which causes close to 1-2 hours of wakelock per day for me. I have root so I can disable it but there's no other way from the app itself.

You can just set the app to not use any background data from within Android. I have it on all that's not important for me.
Loose about 0.3% per hour without any apps or mods on beta 2.

So, the story continues... After following your advice and restricting background data for Instagram the wake up time fixed itself, however battery is still draining. Screenshots attached (facebook and time sensors used??)
I will test every available option and if they won't work, I would consider moving to beta oxygen os. Now I'm on 5.1.11
I am ready to trace this to it's roots for people who will potentially encounter this problem in the future.

It could be your spotty connection. Your awake time is fairly high when the mobile network connection goes south. Can you try using something like 3G instead and see if the awake time goes down? As well as the battery drain?
Naturally 3G uses less battery but if you see a drastic difference then it could be the tower connection you have. When the signal gets worse the modem tries harder and effectively uses more battery trying to stay connected.

Have a look if Facebook is allowed to use unlimited background data, I believe there is a setting for it on 5.1.11 aswell (I'm on beta,its a beast.)

There are many reasons not to install Facebook apps on your phone, and this is one of them.

Background data off both for Facebook and Instagram fixed (at least it seems) the overnight drain issue even with airplane mode on. Last time I lost 20-30%, tonight less than 4-5%
Just when I thought I found what was causing the drain, take a look at this: 20min sot and 20% down in 4.5h
Screens attached, still searching for the issue. Android battery stats show no awake time, but something is definitely draining (app usage insanely high on 80%)

So strange.. I feel we still have 3 options here.. 2 old and one new.
Flash 5.1.11 without wiping anything (you won't loose data so it's just an upgrade)
Flash beta 2 dirty as an upgrade, (you might get device corruptednat boot, press power 2 times and forget about the message) you won't loose any data or apps this way either.
Last option is the least fun, clean install of rom :/. If you ask me, I'd go for beta 2 option, if you wanna run something you know is stable go with 5.1.11.
I didn't run into any issues with beta 2 but some are (I believe user error here..)
Changed my mind.... I have 2 more posible fixes.. (I think)
Hmmm, one more thing I just came to think of is try using SD Maid, now this is just a guess that it will do anything at all..
The other thing is flashing a kernel, something could have happened there after an upgrade or something (just a guess.)
I'm running flash kernel now, it's really good

Thanks for your thoughts, thinking of going to beta 2 since I am on 5.1.11 right now. As for flashing kernel, I've been there with custom roms and kernels with several other phones and in the end most of them (except galaxy s5) were working better on stock ones after a while... However, doesn't rooting void the warranty on OP6?

Beta 2 is really good
48 hours and I'm at 18% with soon 9hrs of screen (usage and SS in battery thread)
As of warranty, no, you will still have full. However this shouldn't have to be done as a "fix" , i was just curious if stock kernel somehow got messed up :s

I would suggest doing a factory reset or uninstall your apps one at a time. Considering it's saying kernel wakelock (could be false positive) I would start go straight to factory reset. If going to Android Pie beta 2 is overall stable and forces a reset anyways, then go ahead and do that instead.

Im just getting 5-6hours SOT on my new op6, is this the normal battery life? Was planning on flashing custom kernels? Any suggestions?

So, I can close this case as SOLVED.
Today, phone was mainly on 4g, doing photos, videos, calls, 4 hours of spotify via bluetooth. 3h50min SOT, 16h standby and still 27% left. Dirty install of Beta 2 fixed it! Thanks for your help!
