"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

Thanks. Like everyone else, I'm going to try this out and report back after a day or so

I'm trying to get into the 'INFO' section to view wake locks for battery usage clues. I've tried *#INFO*1111# (as mentioned here) and the old *#*#INFO*#*# to no avail. Anyone been able to get to the diagnostic screen from the dialer?

Random power drain

Yesterday as I started my day, i pulled my GN from its charger (99%) and made my journey to uni. The trip takes about 50 mins. For the past month now Ive been using poweramp and have had no problems. But when i got to class i realised i had like 25% power during my trip and the back of the GN was a bit warm. I closed all programs and the power drain stopped. I was a bit concerned so a few hours later when i tried playing music again on poweramp but nothing drained the power. So maybe it was a freak occurrence?
So I went to bed last night and the phone was fine. something around 80% power. I woke up 5 hours into my sleep to check on my phone (its a bad habit) and went back to sleep for another 2-3 hours. When i woke up i found my phone had discharged a whole lot of power again randomly in that space of a few hours.
So what the hell happened in that time?! All I did was turn the screen on and turned it off. My usage patterns have not changed.
here is an screen shot of my power usage. You can see the first drop of power, thats nothing of concern as i was playing angry birds space before bed. Then you see the straight line as the phone was idle while i was sleeping. The next drop is when I woke up to check my phone and that's when the discharging happens again. Then you see it recovering when i woke up and closed all the background apps in hope that it would stop the power drain..which it did.

No new apps, but some app updates. I know at least light flow was updated.
this random power discharge is really getting annoying. It happened again today.
A new symptom seems that the video doesnt load on the phone. for example, trying to load youtube or recorded videos saved on my phone.
Originally i thought my 3g was playing up but when it wouldnt load a video i recorded that was a bit unusual. in fact the gallery app froze and crashed.

Did you search the forum and install CPU Spy and Better Battery stats?
Get some data and find out what is causing wakelocks. Your phone has a lot of "wake" time.
See with CPU spy how much it is spending in Deep sleep and with Better Battery stats look what is preventing it from going into that state. If it's an app: simply remove it.

How's your signal service been lately? I get pretty stank reception at work so my gnex gets pretty warm at the top and battery life suffers. I just put it on airplane mode and reset the radio to force it to chill out for awhile

Thanks ill try that. Just installed CPU spy. Is there an alternative to better battery stats? Don't really want to fork out something to debug this.
I originally used OS monitor, and i checked what was running while the abnormal discharge was happening but nothing showed up.
You make a good point about the amount of wake time though. That long stretch where i was sleeping, my phone shouldnt be waking up that much should it? It didnt seem to affect battery life that much.

Better Battery Stats is the one I use and is recommended here a lot. It gives you insight in the wakelocks from the kernel, as well as from apps. Don't know about the alternatives. It's definately about the wakelocks. Your phone should be in Deep Sleep for 90% or so when you don't touch it (depending on your sync frequency off course).

The only account that is sync'ed is my gmail. The other two listed (twitter and dropbox) is turned off. Are there other options to turn the freq of when the phone syncs?
It's so strange because before these problems came about I had good battery life. ie: 3+hours of screen time.

You usually set it at System Settings, accounts & Synchronisation but some apps allow you to set it within the app... There are apps that allow you to make profiles so that, for instance at night, your device turns off all data. I used to use Juicedefender but that was IMHO more a placebo effect then a real improvement.
I definately think you should install the mentioned apps and after such drain re-appeared analyse what happened.

So after a little bit of troubleshooting I narrowed the problem down to Light Flow Lite.
Last night I went to bed with 100% charge. It discharged normally throughout the night until 4 hours in when I received an email. I woke up about an hour later and saw this so i suspected it was light flow. I cleared the notification and went back to sleep. I woke up about 30 mins later and was sad to see that my fears were confirmed. Battery discharge had settled down and was acting as normal. Just to be 100% sure though, i sent an email to myself to set off a notification and left it for another 30 mins, and as you can guess, the battery started draining excessively again.
Here is the screenshot. First part obviously is when im sleeping. then that dip is the email coming in. That TINY TINY dip upwards is another email coming in a min after I cleared the original email. So the battery drain continues until i wake up and clear it again. This time no more notifications came through and the battery drain settles down.
Again keep in mind that I have used Light Flow Light for 2 months now without problems.
Anyone else experience problems with Light flow or Light Flow light since it was updated on the 20th March?

I have been great with my light flow lite..I had a problem with my own battery when I updated Google chrome.. uninstalling that fixed my problem..

Horrible Battery Life

It would seem that after I installed the AT&T update to dumb down thr search on my phone, my battery life has been terrible. Yesterday it was down to about 30% after only 4 hours of light use with the processes "Android OS" and "Cell Standby" taking up the most battery. I can't even get through the day with this phone. Some help would be much appreciated.

After any update, give it a couple days to level out. Until then, just carry an extra charger and plug in when you can.

The update was installed at least a week ago.

In that case, backup everything and do a factory reset when you have a fully charged battery.

Alright I'll give it a shot. I needed to do that anyway as my clipboard no longer works and consistently crashes. :/

I did a factory reset a few weeks ago and that solved it for me.

Do you have any specific methods for backing up a phone that isn't rooted? I've got nova backed up, but I would like to make sure everything else is too.

Are you receiving push email? that was the major drainer for me. apparently the android email app has a bug.
Regarding clipboard...delete everything in data/clipboard; force close the 'test service' app and then restart your phone

The best method would be to use titanium backup but since your not rooted I don't know what options you have except to use the google backup but that ain't to good since its only app data.

Hi all,
Since getting the phone from day one, I really never had a problem with the battery. Lately however, I've noticed a significant drain in battery over night. I tested the drain a few times over several nights, and even put my phone into "airplane" mode to help save battery.
Below are my results from going to sleep at 1:30am with 100% battery power and in airplane mode and waking up at 9:30am the next morning. I get a 12% decrease in battery over night for doing nothing over the course of 8 hours.
The only thing I've noticed differently is that Chrome is starting to use battery which is odd because I rarely use Chrome to begin with.
Any ideas to help this? What should I do?

i second that problem about Chrome. I think it is a bug regarding the builtin flash code. my battery was great until i installed Chrome then it got really bad. I uninstalled Chrome and my battery life jumped up big time. huge different. too bad i really like Chrome but no go right now

Not sure if it's the same issue, but I had some problems with battery life in Chrome until I disabled Tilt Scrolling under Developer Options in the Chrome menu.

my battery life is great even after the update

[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.

Sent from my LG-H815 using Tapatalk

I was having these issues too after upgrading to MM. My battery life was appalling and Facebook was keeping the phone awake for hours at a time. 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.
Sent from my LG-H815 using Tapatalk

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_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"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.
