[Q] Android System = 49% of overall usage?

Just yesterday I noticed that my battery was draining crazy quick while it was in sleep mode. I don't have any background syncing going on other than auto-update for a weather widget once an hour along with the core Google things like contacts, email, calendar, etc.
Usually the screen has been the largest contributor to draining of the battery and via betterbatterystats, there's no abnormal wakes going on.
I did a reset of the phone and I've now disabled 'Data Network Mode' as I'm primarily on Wifi right now. It seems to have fixed itself so far but I'll know better tonight.
Is this a conflict within the OS itself (rooted on Infused V2.1.0) or something from having 4G enabled when I'm in an area where I typically only get 1 bar? Either way, it's a huge draw on my battery...

From what I've heard/read this is a random bug caused by gb, not common at all but ocassionaly android os will go nuts and suck down your battery. Resolutions I've seen posted have just been power off, remove battery, re-insert battery, power up = issues reoslved.

Hmm, I would say try the battery-pull method first. If that doesn't fix it, maybe try flashing back to stock via ODIN and then re-flash Infused? Just an idea.

Disabling apps may cause huge battery drain.

As soon as I got my phone and set it up, I disabled all the AT&T bloatware in addition to google+, twitter, ypmobile, etc. Phone was always running great, but I kept wondering why I could never get over 3 hours screen time.
Fast forward to this morning....I re-enabled every app that I have disabled, and now I'm sitting at 3 hours screen time with 35% battery left. Didn't change anything else.
So I'm not sure why disabling apps caused a huge battery drain (I thought it would help with battery), but it did for me.
Might be something to check out if you are having battery issues.

Weird. Mine last longer. Check your auto-sync settings?

You said as soon as you got your phone set up you did this. That brings a few things to mind:
1) It sounds like it was your first or second battery charge. You need to fully charge/discharge a couple times before the battery's properly configured and you'll experience the device's full battery life.
2) Being that you just set it up, auto-sync would be working overtime for the first-time sync. You know, pulling in all your contacts, emails, calendar events, facebook everything, and so on, causing a higher-than-normal strain on the radio (either wifi or LTE, doesn't matter) and CPU.
Now that your battery's calibrated and your first-time sync is done with, give'er a full charge, disable the same apps again, and let us know how that goes.

I've checked everything. Everything was OK, so I decided to re-enable the apps to see what would happen and now my battery life is where it should be.
Maybe I disabled an app that needs to be enabled or something. I don't feel like figuring out which one it is, so I just enabled all of them.

I mean when I first set up the phone I disabled the apps. I've been using the phone for a few days with the apps disabled, so I just re-enabled them this morning.

This seems counter-intuitive. Until a few more people report similar situations I'm reluctant to believe that it was one of the apps being enabled/disabled that caused and fixed the problem.

I personally disabled all the bloatware that was possible and I've had phenomenal battery life. Sounds like your phone just needs to go through those first couple charge cycles to get the battery going properly.

yeah mate, have to agree with the guys above. i disabled all the ATT crapware and haven't had any problems. sounds like you've got a wake lock somewhere. download CPU Spy from the market and search the forums for Better Battery Stats to find the culprit

I've got quite a few things disabled and I hit 34 hours on a single charge earlier today. Sadly I had to reboot so the uptime chart only shows 24 hours.

After seeing this I've re-enabled all of the HTC bloatware (facebook, twitter, etc.). I have a feeling that my crappy battery life may have something to do with HTC's Sense software somehow trying to interact (with their widgets and whatnot) with my disabled apps. If that doesn't change anything, I'll try to enable AT&T's bloatware too and see if that makes a difference.

battery drain

Hi.. i lost 20% over 5,5 hours in standby mode.. is that normal or something sneaky going on?

Do you have any apps syncing all the time? Some news apps sync every 15 minutes or so.

That seems like a high rate to me. Have you messed with any of the power options on it (made it not go into standby, etc...?)
I barely got that much drain watching a 3 hour movie.

I'd also check email syncing - if you a bunch of accounts that sync very often, it can affect the battery as well.

Also make sure your Bluetooth is turned off.

It happens to me sometimes and it seems like a reboot fixes it.

A reboot does sometimes work. Otherwise also make sure you close out office programs. I've noticed that sometimes runs down battery a little, though not that much. Are you hooked into WiFi, and is the connection where you are reliable?

i uninstalled few apps and rebooted and its okay now.. maybe it was because of Appygeek app.. try it out

Turn off all live tiles (maybe except mail, messaging and people which are useful) and don't allow any lock screen apps to run in the background which you can change via pc settings. This should significantly improve battery life.

[Q] Please Help ! Android System Battery Drain on Nexus 5 after KitKat 4.4.2 update

Hi,
The battery life of my Nexus 5 has taken a dramatic hit since the 4.4.2 update. I think the culprit is Android System but the GSAM battery graph seems to suggest that the culprit is Android OS kernel. My Nexus 5 is on 4.4.2, unrooted, stock ROM and the build no. is KOT49H.
In short, my phone does not seem to have a wakelock issue but I can't verify because 4.4 does not allow wakelock access without root. It sleeps fine at night and in daytime when it is not in use. I only lose around 5% or less overnight with 2x battery turning off the data connection and only turning on data connection once every night. The problem is the Android System which drains at least 17% (sometimes 25%) of battery everyday and routinely sits on top my of battery usage chart with or without me actually using the phone. My usage per charge is typically around 6-7 hours with around 1 hour 45 minutes screen on time. I had extraordinary battery life before the update to 4.4.2 (lasting more than 1 day with over 3 or 4 hours screen on time). Now my battery life is completely shot. The battery graphs attached already represent one of the better days. Some days the Android system will drain at 25% or more. You will note my phone relatively slept fine without draining at night in the first 7 or 8 hours and then the battery drain started to take a nose dive after I woke up. I feel that whenever I start using the phone (with the screen being turned on), the battery drain will occur. My observations are as follows:
1. I use LTE but the reception at my home and work for LTE is not good so the radio jumps between LTE and H+ from time to time however I do not think the radio jumping contributes that much to the drain. The drain stays the same even when I am at a place with good LTE reception. I use wifi at home but i cannot connect to wifi at work (which sadly is another issue). The wifi is always off unless i use it at home. I do NOT have wifi scanning in the settings. I have wifi battery optimization on. I never use bluetooth.
2. My google now is off. My location setting is completely off with no location reporting etc..
3. My Google + auto back up is off. I do not use Facebook, Facebook messenger, Instagram, snapchat etc. I mostly use Feedly, Whatsapp, Gmails and look at stock quotes every day. I seldom take pictures, videos or listen to music.
4. I only have one widget dashclock widget. I have removed feedly and stock quote widgets from the home screen but they don't seem to affect my battery usage that much.
5. I use Automateit but only have a few rules such as setting vibrate on weekdays etc.. I do not have any profiles which are related to GPS or location which i understand would drain battery. I also use Dynamic Notification, Light Flow, Lux, Nova Launcher, Notification Toggle and the memory in general is always below 65% in the background. I also use 2x battery to save battery which is set at switching off data after I turn off the screen and it will only turn data in the background every 10 minutes.
6. I have tried safe mode and 9 out of 10 times the Android system drain remains the same. The only way to lower the Android system drain (albeit temporary) is when I turn off the phone and plug it in for a charge, then turn it on when it is full and still plugged in. After I unplug it, the Android System drain will lower to say 7 or 8 % but it will slowly creep back up to 20% within an hour or so.
7. The CPU usage overlay routinely has 9 + readings on the top when the screen is turned on (but with no app running). I think it means very high CPU usage.
8. I do not think Feedly is causing any problems. I deleted the app and the drain remains. I also do not think GSAM is that useful as pointed out by another member here. It points to one app. You delete that app and then the drain remains it will point to something else.
9. I have been using Greenify (non-root) but it does not seem to help with my battery drain as the drain might be caused by system apps or processes within the OS.
I don't know what else to do and this problem has been troubling me for more than 1 month now. Please help !
Update on 24/2/2014:
I have given up and factory reset my phone. After I reset my phone, the apps were installed via Google Play automatically. I also switched to ART. It was fine initially for at least one day. The apps were there but I did not use or enable most of them as I wanted to transfer all my data and tweaked the settings in one goal. I mostly just used Feedly, Whatsapp and Maps for navigation. Even with Maps and high accuracy GPS on, the Android System would go below 10% even though it would temporarily increase to say above 20% during navigation. This morning, I thought the battery seemed ok so I enabled Lux, Dynamic Notifications, Lightflow, Automateit, Nova Launcher and restore the settings to most of the apps.
The Android System drain came back within 2 hours and hit 25% of the total battery drain. My phone's battery dropped from 100% to 40 % in less than 5 hours and the screen on time was only around 1 hour! I never did any battery intensive actions. The most was turning on the phone to check my battery and whatsapped less than 10 messages back and forth ! Since the drain re-appeared, I have turned off completely the location setting, Google Now, sync for Google Plus, auto-backup for Google Plus. I have removed all widgets and disabled Dynamic Notifications, Nova Launcher, Light Flow, Lux. The drain still remains the same at 23% or more.
This is driving me absolutely crazy and I am sick and tired of spending so much time and energy on sorting out the cause for drain (and to no avail!) I spent a lot more time on trying to fix the phone than really utilizing the phone for my benefit !! I just sent an email to the Google tech support and hope they will help instead of sending me generic self-help sheet. Thanks all for listening and trying to help. I am just really disappointed with Google this time.

Use bbs to get wakelock info.
Feedly has got to go too

Thanks for your reply. My N5 is not rooted so I do not have access to wakelock stats anymore.
I have removed Feedly but the android system drain persists.

Not a lot that can be done without knowing the cause. Consider factory reset?

Thanks for your help.

My missus' LG-P880 has exactly the same problem. Just started happening one day. It seems to be wakelock locator alarms according to bbs but there doesn't appear to be any reason for it. Its been driving me mad too. Luckily tho she's rooted so using app opps i disabled Google services location and it's kinda helped

Did you try another kernel ? When I changed to franco kernel, my battery life is better.

having weak LTE signal kills the battery but it should not be this bad.
Maybe you should try a factory reset and see if the problem still persist, if not then you have an rogue app somewhere.

You can use the process of elimination.
Start with disabling Dynamic notifications and Light flow as those have high potential for battery drain.

I had this same problem the other night. Get app ops starter from the play store. In there turn location off in Google play services and android system. Note, this may impact other apps. I don't use any that I need location for so it works for me.
Sent from my Nexus 5

I had a similar issue as well. For me I turned off a couple things and it really helped:
1. Turned off Cerberus, I believe checking location too often or incorrectly or something.
2. Turned off Account sync for Play Newstand. Noticed when a sync would occur, it would hang on Newstand for much too long which I think was waking device and keeping device awake during it's long syncs. Everything else would only take a min or two total.
3. Set G+ photo sync to only sync when on wifi and charging.
4. Removed Yahoo Weather app. Noticed yahoo weather app staying alive a lot too.
5. Removed Whatsapp. Probably unnecessary really, but any of those messaging/weather/location apps that I don't use often (if ever) I removed to make sure they weren't checking location in the background.
So far, I'm at 78% battery today when I would have been at around 30-40% usually, so that combo has made a huge difference.
It's going to be different for everyone I think, but basically just make sure you don't have any excess apps checking location in the background. And at least for me there seems to be something wrong with Play Newsstand sync hanging for long periods of time.

Yea... Even i had the same issues... Latest version killes ma deep sleep mode nd also some of a rules disappeared....

I was having similar issues and was able to narrow it down to syncing Google Services...
I found that often times Google Drive would get hung up when syncing in the background and chew up my battery.
What Google Services do you have set to auto-sync? I would narrow it down to the ones you only really need to have synced in the background and have the others sync up for you when you open them.
Also, in regards to your LTE/H+ signal, have you tried to flash another radio to see if there is any improvement? A poor signal can have a pretty significant impact on battery life as well.
Lastly, as mentioned by another user, Better Battery Stats, though requiring root, will make it a lot easier to track down the culprit of the issue if it indeed a rogue app somewhere.

Try different keyboard. I've a suspicion that latest Google Keyboard is the culprit.
I was having some unexplainable with BBS (no locks, etc.) battery drain. Which can only be resolved (though temporarily) with reboot.
So, I installed alternative keyboard (Swype in my case) and using it. So far, second day I don't have battery drain.

Update
Please refer to the OP for update. Thanks all.

battery after reset
After a second factory reset, I did not install a lot of the apps which I suspect have something to do with my drain - including Swype, Dynamic Notifications, Nova Launcher, LightFlow, Task Manager, 2x battery, Lux, Notification Toggle, Dash Clock, Automateit. I have also set my location to device only with no location history and history. I have also disabled Google Now. I have not restored my photos, music and videos to the phone yet. I have disabled sync for Google Plus, Google Drive etc.. I have also disabled auto back up for Google Plus. I am on ART.
The battery life (with around 25 % left) was around 6 hours 30 minutes or a bit more but with close to 2 hours 40 minutes screen on time. The screen was the biggest draw. Android system comes in second with around 13%. This is obviously better than before where I managed to squeeze maybe a hour or 30 minutes more but with 2x battery turned on in the background. I mostly used the phone for battery checking, whatsapp, Feedly, web surfing. I played games for around 20 minutes. I was not on wifi most of the time. Is this battery performance normal?
Thanks in advance.

Replacement offer by Google

I have reset the phone three times. After the third attempt, the battery drain for Android System would go back up to 20% plus. By the test of elimination, I thought I narrowed down the possible culprit to Light Flow and Dynamic Notifications. I uninstalled both of them but the battery drain remained 20% plus.
Google was willing to replace my device. I asked them whether the battery drain is likely a hardware or a software issue or a combination of both. They said (to my surprise) it is hardware issue. It seems they have come across quite a number of similar cases. I always thought it was a bug within 4.4.2 or in the google apps such as Google Play Services etc. and could be fixed by a patch or something. The phone also means a lot to me as it was a gift from my gf. I just don't want to go through the hassle of replacing the device if it is a software problem but I guess I am running out of choices unless I decide to wait for the update. What do you guys think?

It's definitely not a hardware issue. If you Google it there's threads all over the place with all different makes and models of phones having the same problem and no one can figure out why, apart from it definitely seems something to do with Google services (GmsCore.apk)
Your best option is to root your phone and use app ops and turn location access off for every app that doesn't need it. (pretty much everything apart from maps and weather apps)

[Fixed] Battery issues with 5.1.9

I've got the OP6 since release and haven't had any battery issues until i upgraded to 5.1.9. prior to 5.1.9 I used to get a 1-3% drop overnight. Post 5.1.9 I get about 1-2% per hour of stand-by. The drain is not so high like I have a misbehaving app, my phone sleeps ok with the occasional wake-ups to get notifications. I was just very happy with the SOT and stand-by times i was getting before i upgraded to 5.1.9 and just trying to get back to it.
Also it seems like i'm getting a little bit higher drain from google play services that before, it always shows up third on my battery stats list and before the update it used to be beyond the 8-10th place.
-Already cleared cache from recovery before this battery cycle (Beginning of previous cycle).
-Already cleared google play services Data before the start of this cycle (Beginning of previous cycle).
-Already cleared google app Data before the start of this cycle (Beginning of previous cycle).
-Already cleared app cache before the start of this cycle (Beginning of previous cycle).
-Scanning off, GPS battery saving, overnight data was on 4G not Wifi, advanced (aggressive) optimization on, all apps are being battery optimized.
I've read most related threads and haven't found anything that helped, What should I do?
Also I read on a thread that turning off Android system background process helps, is it safe to do that?
Update:
So I think I found a fix somehow.
-Clear data for all Google play stuff (service, store, games, Google app). Then restart.
- reset network settings.
- Also I traveled to another country and not using dual SIM as I was and only on one SIM now with LTE.
- stopped using maildroid and used Gmail for work email. It's the app I suspected to mess with my standby drain.
- Also I have found an anomaly with Google photos. There are three settings to back-up Google photos and all three do not talk to each other:
1- Within the app itself. Google photos> settings> backup & sync
2- Phone options> Google> Google photos backup
This one doesn't appear all the time, sometimes it's there and sometimes it's not! Haven't figured out why it sometimes show and sometimes not though, but last time it showed I made sure it's off)
3- Accounts> Google > Google photos backup
(Screenshots below)
All the above three options don't talk to each other at all. so if you have it turned off within the app and the Google settings menu it can still be on within the accounts menu.
I think that causes sync issues which leads to battery drain specially in standby.
My current setup that do not drain battery is as follows:
1- Google photos> settings> backup & sync (ON)
2- Phone options> Google> Google photos backup (OFF)
3- Accounts> Google > Google photos backup (OFF)
I get my photos synced on wifi without issues and no extra battery drain.
When I found out thy don't talk to each other and turned them all on (specially the one in the Google settings menu) I started getting extra battery drain and Google play services showed up persistently in my top three battery usage items. Screenshots in comments.
Standby drain is now back at 2-3% overnight.

Heres some of the things I do to maximize battery,
Every one is different though,but these work for me
Use dark theme always
Don't use aggressive doze
Don't optimize apps that you really need notifications from
Turn off Bluetooth,location
Use nova launcher with dark theme
Low to medium brightness,no auto brightness
Clear cache from cached data in storage regularly
Occasionally do deep clear from advanced
Don't use face unlock
Turn off unused gestures,
Just some tips,but I do get small battery drain at night anyway, I don't think you should worry about it

Just a recommendation I got before from users on OnePlus forums, the concensous generally there is to just use normal optimization.It does seem to drain less

I've been using advanced optimization since I got the phone and was getting very good results up until my aforementioned problem. Will give it a shot.

settings/wifi/wifi preferences/advance
check for keepwifi on during sleep...put never
check network notification...switch off
i hope this works

Nothing to do man, bull**** to use more 'optimization' by turning wifi off, using theme and other things. I mean we should use the phone how we want right?
Just wait for a new update...
All OP6 users got standby draining. Annoying asf.

Just a note, clearing cache in recovery does nothing. This phone doesn't have a cache partition.

Try restoring network settings.
*Settings, backup and reset, network settings reset*
This helped me when I was on Samsung s7-e when I had some strange drains from an update.
I have no issues with my device on 5.1.9

You are right 100%..this is obviusly semi product..i fight with their support team, already change with them more than 30 mails, they just ask screen shoots for this ss for that...they should give money back, in my hand phone go crazy just like that loose overnight 36% with everiting off. Sometimes during day too. I have this problems since i get OP6, 4 weeks ago.

I was using the same settings since I bought OnePlus (OOS 5.1.3) and I had an amazing battery life on OOS 5.1.5, but since 5.1.8 also 5.1.9, battery life sux. It is a problem with the software. In their opinion I should turn off all the features, even take out the sim card, maybe I should turn off the phone to save battery...

Feels bad man. The Chinese Oxygen version did fix the battery drain issue on 5.1.10. So we can expect it to.
Or you downgrade to before 5.1.8 and update when 5.1.10 is out.
Or you just wait. Don't do these 'battery optimization'. Not needed when the OS is the problem. And not your personal usage.

So I think I found a fix somehow.
-Clear data for all Google play stuff (service, store, games, Google app). Then restart.
- reset network settings.
- Also I traveled to another country and not using dual SIM as I was and only on one SIM now with LTE.
- stopped using maildroid and used Gmail for work email. It's the app I suspected to mess with my standby drain.
- also I noticed an anomaly with Google photos
Standby drain 3% overnight with 6-7 hours sot depending on usage. (Screenshot below).
now after I got good results Im using maildroid for this cycle to see if it had any effect or not.

Also I have found an anomaly with Google photos. There are three settings to back-up Google photos and all three do not talk to each other:
1- Within the app itself. Google photos> settings> backup & sync
2- Phone options> Google> Google photos backup
This one doesn't appear all the time, sometimes it's there and sometimes it's not! Haven't figured out why it sometimes show and sometimes not though, but last time it showed I made sure it's off)
3- Accounts> Google > Google photos backup

All the above three options don't talk to each other at all. so if you have it turned off within the app and the Google settings menu it can still be on within the accounts menu.
I think that causes sync issues which leads to battery drain specially in standby.
My current setup that do not drain battery is as follows:
1- Google photos> settings> backup & sync (ON)
2- Phone options> Google> Google photos backup (OFF)
3- Accounts> Google > Google photos backup (OFF)
I get my photos synced on wifi without issues and no extra battery drain.
When I found out thy don't talk to each other and turned them all on (specially the one in the Google settings menu) I started getting extra battery drain and Google play services showed up persistently in my top three battery usage items.

Weird thing is that I do not have the backup options under the phone settings under google or under account.
The only place it shows to backup photos is within the google photos app itself
