Extreme Battery Drain

My phone's battery is constantly being drained by one thing or another. I shut off location services, and Google Search becomes the problem. I shut off Google Search, and Play Services drains the battery. I uninstalled Play Services and now my battery use looks like this.

I don't know what to do. Is it time for a factory reset? I am rooted, but stock. I assume I would have to unroot before a reset.

Give us some specific numbers and we might be able to help. The screenshot you put up means nothing. Either more info or BBS screenshots (or maybe even Wakelock Detector)

Yeah, hop on Android Market. Download Wakelock Detector and the next time you pull it off of the charger leave it be for a couple hours. It'll keep track of what is keeping your phone from sleeping. For example your phone can be awake without the screen being on, and that's probably where the issue lies. Make sure it's set to CPU Wakelock. Then come back with some screens of that. We'll get a better idea of what we me be able to do to help.

I've been using Wakelock Detector, but I guess I am unable to interpret the results. They seem inconsistent. My phone was recently rebooted and is being charged, but I will post a shot of WD later. The top result earlier today was Google Music (which I almost never use). It did not seem like a terribly long period of time it was on, though. I think it was less than 6 minutes. I turned off sync for it regardless.
I assume BBS BetterBatteryStats. I'll go purchase it.
Thanks for the help. I do appreciate it.

Hm... How long have you had the phone? If you're in the grace period still, it couldn't hurt to replace it. Every now and then, defectives slip through. Knowing how well the G2 battery is supposed be, I do it very unusual that you're suffering a hit in that department.
Edit: I still think there has to be a rogue app somewhere. Especially with android system taking so much of your battery.

Battery is almost full, doesn't seem odd to me with phone sleep. Need wakelock info form BBS.

Battery drain all of a sudden. It's killing me!

Recently my phone has been dying really fast. I checked battery stats and Android system is what's killing it. I've tried everything to make it stop and nothing works. Does anyone else have this problem? Any idea on how to stop this? PLEASE HELP.

Boot into recovery then do clear cache partition. Should clear out whatever is causing this issue unless that app is still in there

Clearing cache could and probably will get rid of it. But I bought an app called Better Battery Stats, (id link it but im new) which tells you exactly what is waking up your phone while its off. Chances are you have a rouge app, that is just destroying your battery, as opposed to a system-wide problem. That app will tell you what it is.

Ignore the battery charging cycle. I'm just showing you what I have to go through also and somewhat fixed the problem.
I have and still have %50 android os usage. Before I did this mod, the android os was the highest usage and showed awake time as well. It was killing my battery from a full charge it drained down to zero in 12 hours with 1hr screen time and the phone never being in a deep sleep. It was aggravating because I wiped my phone so many times, tried different roms, took sim card out, no wifi, wiped cache, and wiped phone with nothing installed. Still the high android still persist and no deep sleep. I'm thinking it has to be Verizon doing something or Google that is waking up the phone.
Some how I fixed it or maybe the OTA fixed it. I odin mj7 and updated to the newest version and flashed beans. From the screen shot it shows my android os still high... but with no awake time. So my phone is actually in deep sleep mode now. It's weird but I semi - fixed it. I'm still clueless on why it's so high when previously screen time usually trumps as the number one usage spot. I still have no answer to this reason but I hope it helps a bit to fix this issue.

HEY same exact thing here. Android OS usage going nuts here. I personally think its related to certain wifi / router setups.
When im on 3g/4g all day, it doesnt happen. On the days that I am stuck at home on wifi, the android OS usage starts again.
Ive already Odin'd back to MI7, took ota to MJE, rerooted, installed beans b5 and its still happening.
I think its a bug with samsung / verizon wifi. Many times I will wake up my screen and see my GPS / Wifi being used for no apparent reason even with all location services turned off. I also notice my wifi indicators being on when i turn my screen on. Then after i turn my screen on and sit at my home screen for a few seconds. It all magically stops.
Mind you, this is with no apps installed other than what is in beans stock and nova launcher.
You guys should monitor while off wifi and see what happens. It was the first thing that struck me when i was on a road trip for 12 hours. My battery life was exceptional. If it is the wifi causing problems, i wonder what it is specifically.

Simply clearing the cache fixes this for me every time. I usually do it once every few weeks.
Settings..storage..tap on cached data and hit clear.

[Q] I9505 4.4.2 android system battery usage

Hi,
Ever since I upgraded my I9505 to 4.4.2 I've noticed that one of my key battery consumers was Android System (not so on 4.3 or 4.2.2, or whatever I was running before). Right now I'm on the latest DBT ROM, but still the same issue. I've been reading numerous threads on this, tried lots of things even formatting my SD card from within the phone, but still same story. I have Google location services disabled (major issue before), Google Now hot word detection is off, S Voice voice activation is off - nada. I am running stock so getting a wakelock report is a no go. I get decent time on the phone (up to 18 hours per charge), but still want to figure out why Android System is using so much battery (it seems to be CPU time related anyway - phone is properly entering deep sleep when it should). Below is a screenshot of what my battery graph looks like about 2 hours after unplugging the phone from the charger with normal usage. Thanks for ideas!

Any ideas? In the meantime I've done a factory reset, disabled Samsung's bundled apps (e.g. S Voice), tried disabling location services altogether - still same story nothing seems to help. In OS monitor I see a constant Android system activity between 1-9%. Average is around 2-3% but it never stops.... Sadly with the KitKat permissions being what they are I can't get more details.
Here's a graph from today 3 hours after a full charge with minimal phone usage:
Clearly something is going wrong here...

Hi ,
With this information is hard to tell what is going on , you need an app like Better Battery Stats
http://forum.xda-developers.com/showthread.php?t=1179809
Let it run for 3 to 4 hours at least and then see who is running wild
Review you settings , location , mail , FB......

Thanks. As I am running non-rooted 4.4.2 I can only see kernel wakelocks which look normal to me:

Upgraded to I9505XXUGNK4 (DBT) today and it looks like it helps!

For posterity's sake - the firmware didn't fix the problem. My Android System, and to some extent Android OS, usage was still pretty bad. After hours of trying various things I've got it though - in my case I had to disable Samsung's Unified Daemon (EUR) and now once more my top consumers are Screen and phone idle! Hope this helps folks.

Huge battery consumption, help needed

Hi all,
I am very satisfied with my device except for the battery life. I always had like 3-4 hours SOT. I was not happy but it was OK.
Lately I started charging the device every day after work (I would come home with dead phone after only 8-9 hours of it being unplugged).
So I thought the battery is defective, I must change it... and I did change it yesterday. The thing is that even the new battery behaves almost the same. It approved somewhat and now I will return home with 10% battery instead of dead phone 1 hour ago. But still the battery is terrible...
Can anyone help me, share some advice on how to improve it? I have disabled many software (even facebook), disabled location... did everything I could think of.
I am thinking some app is drawing the juice but cannot put my finger on any of them.
Some screenshots are attached that might help with your tips/advices.
Thanks!

Are you rooted? On nougat? If so get background restrictor APK here on XDA and kill background apps and tasks so they can't run if you do not open them. Lower screen brightness. Install kernel auditor and shut off cores 4 and 8.

uninstall chrome. Then try accubattery (better bcause after android 7, they join all in android system to mask each app consumption. If after this you still can't find out where's the problem, start the phone in "safe mode". Even the consumption is better in this mode you must do a full wipe in recovery mode (vol up+power+home) and after this, reinstall one app each time and see after reinstall the second one and so on until you find out in which app is draining the battery
If you want you can starting by disabling background data in settings but I think isn't the clearer way to find out

This is going to surprise you.
I've had this phone for years and I've tried everything - and the BEST result is when you DON'T DO ANYTHING except disable Facebook and Instagram, and any Google Apps you don't use.
Do not tamper with anything else.
I figure that Samsung tunes this phone so tightly that if you leave it alone it operates as it should.
Anytime I disabled anything else, battery life suddenly and drastically reduced.
The phones runtime software kicks in and if you have disabled something it checks routinely, it will keep the phone awake constantly looking for a ping back from that process.
I just went through the whole process again meticulously, App by App.
Also DO NOT enhanced messaging OR the device antivirus. If you have, you must reset and then train yourself not to engage these too regardless of how hard The phone tries to persuade you!
Then - the battery life becomes like a normal phone which means you'll still need to charge everyday but it will take you through a full heavy day... And this is fantastic!
Honestly try it and you'll see what I mean. The S6 edge plus is so finely tuned, anything you block will start a feedback loop.

I had similiar problems , the way i fixed it, i disabled/uninstalled all samsung applications what i dont use, i disabled/uninstalled all google applications what i dont use. Cold weather (like -20C) will affect the battery life too.
Disable / uninstall apps you dont need. That helped me a lot and got even more battery life while at stock nougat rom with all updates installed.
try wiping cache from recovery and reboot your phone.
I hope this helps you

Has my battery degraded or its a software issue?

My battery lately has been draining really fast from doing minor tasks. 2-3 months ago I upgraded to the latest MIUI 11.0.4 and noticed a slight increase in drainage but nothing too concerning. For the past few days though, it has become really bad. An example is how today I charged my phone to 100 percent and within 8 hours it is now already down to 75 as I am writing this post.
What I did:
Charged it.
Left it idle for 4 hours
Browsed some Facebook feed for around 15 minutes
Watched YouTube videos for a total of 15-20 minutes
Left idle again for another 2 hours
Just now spent another 20 browsing some Reddit posts
I usually keep my mobile data as well as the WiFi connection turned off all the time and only turn them on when I need to use the phone. I don't have any IM apps running in the background all the time syncing messages except Kik and Snapchat for whom I've set a battery saving modes to close whenever not in use but again, like I said my internet connection is always switched off. I keep my screen brightness low all the time as well btw.
I usually charge it as soon as it goes down to 30-40%
Pretty sure tomorrow after a whole day of work having it sit idle and then doing some minor internet browsing its gonna drop to 30-40.
Here's a screenshot of my battery stats:

Not sure if this is normal as I remember it draining way slower than it does nowadays. I know that this phone is known for having a good battery life. Any suggestions on what I should do? Is there warranty for the battery in case it turns out to be faulty? I've been using this phone for a little over 6 months now.

I have terrible wakelock on 11.0.4.0.
Non rooted and I want to keep it like this.
Is it a common issue and should I go back to MIUI 10?

Hi, bro!
I had this wakelock in all versions (Android 8 or 9) I tried several times to find out which app does this, installing monitors made for it and so far nothing ... But yesterday I reset my RN7 and the wakelock didn't come back. I imagine it is an app that has not yet performed the initial configuration.

switch aosp(no gapps recommended)
i get 12 hours plus sot

Multiple apps. Of course I tried to fix it by deleting a couple of apps such as restricting the background activity in the most of the rest but I only succeeded to reduce the wakelock from 98% to 50%. The bad thing is, that if You do hard reset it's a temporary solution. Wakelock will return in maximum one month. So what is the solution? Returning to Miui 10 or AOSP rom if You want to run latest Android version?
