"Android OS" consuming battery [POTENTIAL SOLUTION]

EDIT
I was able to solve my battery issue by formatting my SD card. Something on there was causing the battery to drain 2-3 times more quickly than normal. After formatting, I went from 6-8 hour battery life to around 20 hours with significant usage (Google, Exchange, IMAP, Facebook all on push, 3G+Bluetooth+GPS on, 4G and wifi as needed for extra speed).
Important to note, I am not entirely convinced that the Android OS and battery drain are related since I still have Android OS near if not at the top of my battery consumption screen, but the improved actual longevity is very significant. I recommend anyone having their battery run out format their SD card (and possibly USB storage) and see if that helps (obviously back up any important data first!). Good luck!
ORIGINAL POST
I'm getting pretty bad battery life, and it looks like "Android OS" is consuming most of it. I've rebooted (as suggested in other threads), checked OS Monitor for high-CPU usage processes, but nothing stands out. This is un-rooted, stock OS with no third party launchers installed.
I have a feeling if this issue was fixed, I'd be getting great battery life. This happening to anyone else?
Screenshots show the device at 38% after 6.5 hours off the charger.

My device is running 2.3.4.

That's an awful lot of awake time with no screen on time. Do you have things updating in the background frequently? I.e. social hub, Facebook, news widgets?
And not to be too obvious, but is your 4g antenna turned on?

No, I don't. I have fewer widgets and fewer accounts (haven't set up my work Exchange yet) than I previously had on my EVO, which got great battery life.
I've been on Android over a year and am quite familiar with how it works... I'm just unfamiliar with Samsung specifically and unrooted devices and was hoping someone might have a similar experience.

I have the same thing. Significantly more awake time then screen on time, and Android OS eating the battery. Also stock.

Same here too

I had this exact issue and no longer do. Here is what I did and posted in another thread:
OK I hope someone finds this useful and/or can verify. I was one of those people getting awful battery life, meaning lucky to last 8 hours from 100% to 0%. The "Android OS" process would take hours of CPU time. Now it will take up maybe 30 min over the course of the day. Here is the only thing I did between the time it went from bad to good. I changed the wifi sleep policy. It is by default (for me at least) set to never. I changed it to "when the screen turns off" and left it there for about an hour. Then went in and changed it back to never. From the point of doing this my battery life has been great.
I know it sounds strange but it seems to have worked for me so I thought I would share.

I made the change, hopefully it will help, although I'm reluctant since I haven't had wifi on all day and my battery has been dropping like a rock. Here's hoping... will report back if it helps.

I rarely use wifi as well but this setting seemed to affect the phone in general, if your using wifi or not. I might just be crazy though. Either way I no longer have the issue so

does the google voice widget pull data in the background or is it a push thing?

I'm seeing high usage (60+%) by AndroidOS also (stock, unrooted, not using WiFi, not using 4G), although battery life has not been bad that I have noticed.
Watchdog Lite indicates that this is primarily due to two processes:
events/0
suspend

Massive drain battery

Hi,
I have huge problem which hasn't occurred for the first time. I left my t520 with 92% and fell asleep. When I woke up it was at 40%. I had wifi off, and turned off wifi scanning when eve n off (which caused drain esrlier). According to wake lock detector the process which keeps running can be seen under. Please help me. In settings it only says that android process (97% usage of battery) has used CPU for 10h42mi and stood awake for 7h45min

i would suggest go into settings....->battery. this should show u what is using your battery the most. if its a app delete it and see if it works. if not i would recomend doing a factory reset. this is what i do when something eats my battery alot.

Are you using Songza? It has big problems right now with battery drain. The deal is, is probably not the device. There is an app that is causing your issue.
Sent from my SM-T320 using XDA Premium 4 mobile app

The tab yesterday got from 30% to complete 0% with everything off (aeroplane mode, sync off etc.) just laying on the desk.
In settings its shows that battery is drained only by Android process.
I was thinking about what might be the cause and just realised that it started to happen just affter purchase of original samsung case for this tab. Is it possible that it had impact on one of the processes? Cause CPU is active almost all the time despite neither app running in the background... Maybe it's due to the magnetic thingy which wakes the screen?

If the magnet is turning the tablet on, the screen would be on, and you can see that even with the cover of the case closed. So if you can see the screen if off, then I would say no, the magnet is not causing your drain problem.
Do you have Skype installed? This is a known battery drain problem on Kitkat as well. Its a bug within Kitkat itself, so maybe that is why its being reported as the Android process, and not one of your apps.

take a screenshot of you battery

I don't think it's an app problem. I have only few apps installed (news reader, 2 games, fb and few random apps. I'll upload the screenshot when I'll be at home

Yep, my battery has started playing up. It likes to say it's 21% but then goes to 15, then between 2 and 4 within a couple of minutes. Sometimes runs on 1% for ages. But then dies, I turn it back on and it says 21%
Don't know if is root related. Our if I just need a hard reset. Going to try draining battery fully, then charging to full with device off

I also have never seen such a huge battery drain on any samsung or android device. For once, if you dont need it, go into settings and location services. Just disable it completly with that switch. This reduces the drain a lot, but is still way to high...
For me, it drains about 20% overnight with location on (completly offline) and about 10% without location services.

I have the same problem as well. It will continuously drain from 90-50 in minutes and then 50-15 and so on. 1% sometimes lasts for 30 minutes+ and when I restart it will be 15+% again. I thought it might be because of custom roms so I reset it back to stock many times and same problem. The only apps I have installed are adobe reader and es file manager.

boy, you're digging out a two year old thread!!
if you have such a battery drain you have different (unsatisfying) choices:
1. try battery calibration or other roms
2. throw you tab away + buy a new one
3. buy a new battery
4. accept it (like me)
5. wait until someone brings an awesome new rom which will give an awesome battery life
(sorry for hidden sarcasm but this tablet is just a big disappointment (for me))

I don't think you should throw away devices or buy new batteries without first analyzing what the problem could be. If you are rooted, download an app such as Wakelock Detector and BetterBatteryStats first, make sure there isn't some rogue app or process that is constantly running in the background. Also, if you are running the 8.4 (or perhaps it also works with the 10.1 / 12.1), check out the link in my signature on how to reseat your battery. Many people have found success with all kinds of battery problems.

Sudden battery drain - how to tell what caused it?

My Zenwatch usually consumes <50% of its battery during a typical day. Today however it was completely dead by 7pm, even though there was nothing unusual about the day - it was worn at the same location all day, and was in close proximity to my phone all day.
Is there any way of tracing what causes this sort of sudden battery drain?

Hello,
same Problem here.
You can use the "Android Wear" app, connect to your watch and press the gear wheel on the upper right, then press on the first entry " Asus Zenwatch 2" and then you see the option "Battery of the watch" in the middled of the screen. It looks the same as you can see it on the telephone but for you watch battery.
I made a few screenshots today:

now there has something started sucking the battery empty....
now it has stopped... but only for a moment - later it came back and at 15:30 I had only 13% left. I noticed that the temperature display still was showing 7°C but my car display shows 16".
I restarted the watch now and voilá the temp changed to 16°... very stange
And this is the second watch - the first one I send back to Amazon because of the same "bug" ....

For some reason I can't see any of your screenshots. Any chance or re-uploading them?

I think he was trying to upload a screenshot like the one I attached to this post, it's basically a similar battery usage indicator like the one for the Android phone itself. I don't have anything on here really, yet, because it hasn't been too long since I took it off the charger.

Asus Zentalk forum has walkthroughs
The Asus ZenTalk forum has a walk-through with pictures on how to get to the battery use screen. (I'd post the link for you, but I don't have enough posts yet to post links).

I just had the same problem happen this evening. Everything was fine until about 8pm, with 70% remaining, then two hours later it had plummeted to 15%. I checked the battery stats in the Android Wear app, as suggested, but they didn't help: there were only 2 lines:
- Watch Idle: 5%
- Screen: 2%

That is a pretty drastic and sudden drop. What watch face were you using? Did the watch do (vibrate?) or alert you to anything (view messages, receive a call, etc) during that time?
What are each of your settings in the settings area (what features do you have turned on or off)? If you have wifi turned on where you in an area where it may have been attempting to connect to nearby wifi networks and repeatedly failing (like trying to connect to networks where there are sign-on pages where you have to agree to a user agreement before connecting to a free wifi network)?
If you look at your phone battery usage during that same time (if you still can) does it show anything highly active on your phone during that time? (For example could the phone have been trying to update any of the files or apps on your watch during that time?).

To answer your questions:
- What watch face were you using? Perfection (although the last time I had this problem I was using the Explorer watchface)
- Did the watch do (vibrate?) or alert you to anything (view messages, receive a call, etc) during that time? No - I just got a few notifications when emails came in
- What are each of your settings in the settings area?
- Brightness: 3
- Font size: Normal
- Always on screen: Off
- Wrist gestures: On
- Screen lock: Off
- If you have wifi turned on where you in an area where it may have been attempting to connect to nearby wifi networks and repeatedly failing - No, I was at
home in my study and lounge (within 15 feet of my wifi router at all times)
- If you look at your phone battery usage during that same time (if you still can) does it show anything highly active on your phone during that time? I don't have the ability to look at yesterday's phone battery stats, but I know that there were no app updates or unusual notifications on the phone during that period yesterday

In the days that have followed did the problem of sudden drain continue to occur, or does it appear to have been an isolated incident?
In that time period it experienced the drastic drop were you doing anything repeatedly? (ex: eating food, exercising, reading a book?) Repetitive tasks where you wrist was moving a lot may have been turning on your watch using the wrist gestures, and it seems that wrist gestures (where the brightness level 3, color, etc are activated) may use more battery than always on in its timed-out dim mode does. If you're continuing to experience the problem try going a day with always on screen turned on, wrist gestures turned off, and see if there is a difference in your battery use at the end of the day.
Your watch may also be preforming syncing with your phone at a particular time, and transfer of data across wifi between the two may be draining the battery. You could try turning off the sync setting on your phone for a day, and see if that makes a difference.
Finally you can try turning off wifi, and see how much longer your battery lasts with wifi switched off on the watch.

In the period when it dropped drastically I was sitting on the sofa watching TV. There were no repetitive tasks. In fact I could probably not have been less mobile!
I now have "always on" mode enabled, and have disabled tilt-to-wake. So far it has maintained the usual (low) battery usage, so I'll wait and see if I get a recurrence of the problem.
The problem with turning off sync for a day is that it's unlikely to prove anything. This problem only happens every few weeks, so if it doesn't happen on the day that I have sync turned off then I'll be no wiser.
I'm not sure what you mean by turning off wifi on the watch - do you mean putting it into airplane mode? If I do I would fully expect my battery life to improve, but how would that prove whether it was the potential cause of the rapid 2-hour drain?
I'm watching my watch battery levels very closely at the moment, but if I do notice a sudden drain again what can I do to establish exactly what is happening on the watch at the time? If the watchface is displayed as usual, and there's no evidence of any specific app running on the watch, what other options do I have for finding the cause of the excess battery drain?

After 4 weeks I've just had the same problem on 2 consecutive days. At the end of the first day I notiiced that the "tilt-to-wake" option had become re-enabled (I'm not sure how, as I don't remember enabling it). I disabled it again last night, but today my battery was pretty much dead by 9pm. I tried a reboot earlier in the day, but it didn't seem to help.
The latest version of the Android Wear app seems to have removed all info on battery usage, so this is impossible to diagnose. As things stand, the watch has gone from being an all-day device to a device that won't last a whole day in the last days (

Rather than trouble shooting you should just go for a completely new set up of the watch. Uninstall the wear and ZenWatch manager apps, factory reset the watch and reinstall everything.
I've gone from just under a day to an insane 3-4 days battery life. (I don't use any fitness trackers or ambient mode btw)

So today the problem seems to have gone away. For the first time since the weekend I got through the whole day with only 40% battery usage. This battery drain issue seems completely random, and it's annoying that there's no way of diagnosing it.
Surprised that more people aren't seeing this.

Ah OK I'm still on 1.4.0.2462440.gms and the Play Store isn't showing an update available yet. Fingers crossed I'll get it soon, and that the battery info actually gives me some useful information when I see it draining fast next time.

[MM] Got Poor Battery Life? No Deep Sleep - Possible reasons, and possible fix inside

Like a lot of people I found myself with battery woes on the G4, at first my battery was comparable to my G3, if not a little bit better but over time, and certainly since MM was released, my battery life was quite frankly awful.
Long Story
I was losing power rapidly, even when I was barely touching the phone - so I finally decided to look into it. After carefully monitoring apps, wakelocks etc nothing looked out of place, everything was working normally until I installed my old faithful app - SetCPU, this is a nice basic app that just shows what your CPU has clocked too and how long it spent there in a given timescale and one thing alarmed me greatly. I was getting less than one minute of deep sleep in every 60 minutes the phone was running - now if I had been using the phone for 58 minutes of that hour I would expect this, only I hadn't!
I did more testing, and more testing and more testing but the results were the same, the phone barely entered deep sleep, and when it did it didn't stay there very long.
Now as I said, using all the other apps, and android stats, nothing looked particularly out of place and after a few days of trying everything under the sun to fix the problem I decided to go nuclear. I wiped the phone, installed no third party apps but setcpu and began testing. I left the phone for a period of 10 minutes to see what the deep sleep value was (looking for it to be somewhere between 80 and 100% of time, which it was!) and it seemed to be back to normal, working fine. So then I started to install my core apps, one by one running the same 10 minute test between each one, idea being eventually I would hit whatever app it was that caused me problems.
So I installed upwards of 30 apps, and everything was still fine, in 10 minutes of not using my phone I was getting around 9 minutes of deep sleep, which is what you would expect.
And then came facebook, now I know there are lots of reports of facebook being a bad app blah blah blah, but I have never seen facebook react like this before, and I don't know if it was marshmallow or a mixture of marshmallow and LG - but when facebook is installed my phone stopped sleeping again, at first it wasn't a huge change, but was noticeable it dropped to deep sleeping at about the 40% mark so I had 4 minutes deep sleep in my 10 minute test - force closing facebook made no difference, I tested it again and again, rebooted and again - same results.
I then installed facebook messenger, and my deep sleep dropped again, to about 20%.
I then uninstalled messenger - no change.
I then rebooted - back to 40%
I then removed facebook - no change
I then rebooted - back to 80+ %.
TLDR: The "Solution"
Now for some of you this won't be a solution as you will claim you need the apps, but there are third party alternatives out there that work pretty well without causing this issue.
Facebook (and facebook messenger) on stock MM builds (at least on the G4) causes the phone to hardly ever enter "deep sleep", this means it is always running a CPU clock, albeit the lowest setting, but it consumes far more power than it needs too especially when the phone is not in use.
After removing them my phone is now sleeping fine and my battery life is back to being very good - lost 4% in the last 8 hours (albeit idle, I was asleep), which is much better than losing 4% an hour that I was before facebook was removed.
Go give it a try, install setcpu, reset the timer close go back to your home screen then leave your phone for 10 minutes then check your deep sleep values, then try it after removing facebook (and rebooting).
Let me know how you get on.

I simply did a full factory reset, and then restored my phone from the most recent backup. My battery life is now excellent, even with Facebook and Messenger installed

There was a wakelock introduced with the new version of facebook about a week ago not sure if it is still relevant. It goes by the name of bugreporting service. Something like that. The same goes with FB messenger. I got pissed off with the official app because of this and got Metal instead

I don't run Facebook (never have) or any messaging other than Hangouts and battery is always great (2-3 days). If you don't need it...uninstall it.
Kindle app was always a great one for running constantly in the background for no reason. So I bought an actual Kindle and didn't use the app.

I totally agree with the OP, I started having the exact issues after I updated to the latest facebook and messenger apps and my phone was entering deep sleep at all. I removed them last night and its much much better now.

My girlfriend's g3 with mm gets this message lots of time

Until a few weeks ago, the Facebook app had a setting where you could choose the sync frequency and I was able to set mine to every 4 hours.
This setting appears to have disappeared now. Could this be the problem?

Nope. It's not the solution. I uninstalled Facebook but am barely getting 2+ hours of screen-on time on v20b.
A Redditor mentioned that some process called 'logd' is eating up resources and killing battery life. I used Terminal Emulator to verify it.

logd is a separate issue that no one has quite worked out what is causing it - it is to do with error reporting, either from LG or Google apps.

That redditor here. Logd isn't actually logging anything when its CPU usage hits 16% (the problem). You can verify by running logcat in adb shell while watching cpu usage in terminal emulator on phone.
I removed logd by renaming the binary, it's over doubled by SOT from 1-2h to 4+h. As this is my first post on xda I can't link the thread I made on reddit about it -- but you'll find it on /r/lgg4 on the first page ("PSA: How to fix 6.0 / marshmallow logd battery drain (TWRP/root)")

Deep Sleep vs. Awake (Screen Off)

I installed BetterBatteryStats on my phone and was checking some of the stats today.
The following information called up my attention:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
During this period, the phone screen was off most of the time (at least 5 hours), but the phone remained in "Deep Sleep" mode for just a short period (12 minutes). The rest of the time, the phone was in a state called "Awake (Screen Off)", which I don't recall from my previous Android phones.
Did anyone else notice a similar behavior? Is that normal or should I be looking for apps that may be causing wakelocks?
My phone is still unrooted and running OxygenOS 3.2.7.
I was wondering if this behavior may be related to the OnePlus 3 gestures, which I have enabled on my phone.
Any ideas?

Not normal. Try installing wakelock detector and see what is causing this

OK, thanks.
I'm now running both Wakelock Detector and BetterBatteryStats. I don't have root, but I figured both apps have a way of detecting wakelocks on non-root devices.
My first suspicion was WhatsApp Web, which I had been using lately. So I stopped using it for a while. I also disabled the OnePlus Screen Gestures to see if there was any change.
Even then, my phone is not going to Deep Sleep as much as it should. I took some new measurements overnight. The phone was not connected to the charger and was idle the whole time (screen off, no use). I expected at least 6 hours of Deep Sleep. But I got 1 hour of Deep Sleep and 7 hours of Awake (Screen Off). I'm attaching several screenshots of this scenario. During this time, the phone was connected to my Wifi network and bluetooth was enabled (the phone was connected to an Android smartwatch). Do you think that might be preventing the phone from going to Deep Sleep? Any other ideas?
Thanks a lot

Mmm... I guess I finally found the culprit!
I decided to uninstall the Android Wear app, the Google Fit app and disable bluetooth. My phone is now going to Deep Sleep as it should. The battery usage decreased from 5,3% per hour to 0,9% per hour, which is just a massive difference! I'm attaching screenshots of the battery stats after getting rid of Android Wear.
Too bad Android Wear is actually an app I wanted to use... Anyone had similar issues? Anything I can do to keep using Android Wear and have a decent battery usage?

Actually, I'm not really sure if the culprit was Android Wear or Google Fit (or a combination of both).
I'll perform a few more tests and report my findings here.

I'm confirming that Android Wear / Bluetooth is causing the battery issues.
Google Fit is responsible for a few wakelocks as well, but the battery drain is not significant.
I'm attaching a few screenshots showing that a process called bluedroid_timer is preventing the phone from going to deep sleep. This wakelock is related to the bluetooth connection in Android Wear. This is very annoying because I can't use my watch and have my phone's battery lasting a full day. Anyone else having this issue? Suggestions?
I googled the issue and found similar reports, but none of the workarounds seem to work:

I performed a few more tests and realized that the battery issue is indeed related to Bluetooth, but not to Android Wear!
I had the following app installed on my device:
https://play.google.com/store/apps/details?id=br.com.edeploy.gol.checkin.activities
After uninstalling this app, the bluedroid_timer wakelock disappeared and my phone is going to Deep Sleep as it should (even if I enable Bluetooth and use Android Wear). It appears that this specific app uses the android-beacon-library (BLE beacons), which causes wakelocks even if I'm not using the app.
Problem solved for now!

Hello @tiagobt,
could you explain me how did you show up the statistic window containing total awake time, deep sleep, screen ontime, awake time, etc ?

Just tap the orange/green bar on top of the screen.

In betterbatterystat my Awake (screen off) is 100%. What does it mean? Is it the lower percentage better or higher percentage like 100% better? I've attached the screenshot.

Awake(screen off) means that the screen was off but the phone was active and this value should be as low as possible. However this screenshot doesn't establish anything since it is not equal to an idle dump in BBS.
Visit the BBS thread, learn how to produce an idle dump and then post one in that thread and seek help.

I've attached the screensho, why everything shown as 100%? is it that if battery level is below 10%, or shoes like that?

The screenshot shows the "from" reference as "Unplugged" but no "To" reference is shown. Go into the BBS settings and enable the options to show the "From" reference as "screen on" , and the "To" reference as "current" and "screen off" etc. That should sort out the issue.

Can you please tell us how did you figure out which app is causing this? I have a similar issue where most of the battery is going for Android System and Google Play Services. I am on Mi9T with MIUI 12.
