"Android System" draining battery... Facebook is a potential culprit

Hey, I was wondering if anyone else was having a problem with sub par battery life. I have not been satisfied with my G2 battery life, I only get about 12-13 hours and I am not a really heavy user. I have disabled wifi, bluetooth, gps, cell location, and syncing for everything but my gmail and exchange (set to push), and it didnt affect my battery life at all.
I noticed that "Android System" was taking up 35% of my battery, which I am pretty sure is not normal, so I decided to try a different battery monitoring app to get more details. I downloaded PowerTutor and it was showing that Facebook was using a LOT of battery life over the period of about 10 minutes, which was strange considering that I had turned off all notifications, turned off the refresh, and turned off syncing. It shouldn't have been doing anything.
I logged out of the facebook app and it no longer seemed to be doing anything. My facebook version is 1.3.2. Hopefully this will give me some better battery life (right now i am at 24% at 3:00pm after unplugging at 6:30am, but PowerTutor ate a good bit of battery life while it was monitoring)
Just thought I would post for people who might have abnormally low battery life, and see if anyone else had the same problem.
The facebook app is terrible anyways, I won't miss it. I just use a shortcut on my home screen to m.facebook.com
I'll post back tomorrow and see if my battery life has improved.

i get 12-13 hours, moderate use... but i do have facebook refreshing hour... I had no idea it was eating battery while sitting idle though :-\ that's something for me to look into
I also didn't know 12-13 hours was considered low (new to Android)
Thanks for the heads up

I've been doing a little digging on the Adroid System battery drain issues over here: http://forum.xda-developers.com/showthread.php?t=801244. I don't use the Facebook app at all, but I have noticed a Facebook still periodically pops up in logcat. If I get around to it I'll login to the Facebook app and enable updating to see how often it show up then.

Get the currentwidget app and put it up as a widget at the home screen (I come from WM 6.5.5). Set it up using the default setting. Click the power button and let it sleep. Wake it up in 4 minutes and check your Ma shown in the widget. I'm getting 35Ma and my battery seems to be doing fine.
Its tells you how much power is being used by your phone when it sleeps. Also remove any task killer on your phone. You don't need it.

My battery has also been draining pretty fast. Android system says its using 45% percent of the battery. Don't know what to do?

I just did some more testing with PowerTutor. The e-mail app (not gmail) is using up TONS of power when my phone is locked. I think it may have to do something with Exchange and ActiveSync. It's a hotmail address that I'm synced to. I guess I'm going to forward it to a gmail account or something. Its sapping battery life with both Push settings and Every 10 Minute settings.

lol. app dev for facebook hates ios and android. though the fb for android does suck(doesn't have half the things ios version has) but its still better then nothing. fb app is pretty buggy so not surprised that it would take up so much juice.

You could also use watchdog and kill Facebook if it's the culprite. It will also tell you if something else is to blame.

I think that Facebook is the culprit. At least for me it was. I was sitting at android system using ~35% and once I logged out of the Facebook app I checked back about 5 or so hours later and it went down to 12% or so.

But i like that FB app only thing I disliked was getting sent to the web when checking notifications. Maybe social scope will alleviate that

It's looking to me that Facebook was using a decent chunk of battery. Android system is down to 19% for me today after signing out of facebook. I've been listening to music all morning too so thats probably why its still high-ish.
When I get home from work I'm going to monitor my battery again and see if the e-mail app is still using up battery.
If someone else has logged out of facebook and saw battery usage go down, then I think it is safe to say that the app is buggy.

wow... so are you telling me my battery life will go from 12+ hours to 16-17 if i log out of facebook? YOWZERS

When I posted this thread yesterday I was at 24% at 3pm. Right now, at 1pm after logging out of facebook last night and unplugging this morning at the exact same time, my battery is at 68%. I have been listening to music all morning too, browsing the web periodically, and I got a few short phone calls. So unless my battery life tanks 40% in the next 2 hours, I think that being logged in to facebook definitely seems to be eating up battery on the G2.
My testing is hardly scientific, though. But I have had the phone unplugged for 6 hours and 40 minutes and im only down to 68%. Not bad at all.
Someone else should try testing a day logged in to facebook (with notifications, syncing, and refresh all off) and a day logged out of facebook.
edit: also, my Android System is down to 15%. much better.

What about the Twitter app?
And turning off background data won't stop Facebook from draining battery?

I'm not sure, I don't use twitter. And I haven't tried turning off background data, I'm trying to narrow down my battery issues to an application specific level. I'd rather turn off facebook for being a battery hog than turn off all of my background data.

Am testing that one out. However, I have just the syncing on but I don't think that syncs constantly. We'll see how my phone fares with that setting I have now with notifications and refresh both being off but still logged on the Facebook app. My phone averages around 10-12 hours per charge even with using Trillian and AndChat and quite a copious amount of texting during the event hours. I changed the Facebook settings last night. We'll see how the day goes with the battery.

For me, just turning off notifications and refresh didn't help battery life. I had everything turned off and it was still draining battery (what it was doing? I have no clue... shouldn't have been doing anything.. I think the application has a bug)

Loged off Fb and twitter and the battery lasted all day no problems! Also turned off GPS seeing as I rarley use google maps and now very happy with my G2 batt. Thx!

[HELP] Battery Drain, 35% drop in 10 hours

This has been plaguing my phone for a few months i can't even get 24 hours without it dieing. I can't figure out what the problem is and i have tried everything except a full wipe which i want to avoid.
Before i would get about 2 days with normal usage (few calls, browsing the net, msn, music and little bit of gaming)
Now when i unplug it at 7AM it is almost dead by 3PM (15%) but nothing has changed so i can figure out where the drain is coming from. I'm using Doc 9.6.6 (was on 9.1.4 and did a NO WIPE of 9.6.6 yesterday to see if i could get better battery) and SpeedMod K13C 500.
Everything that uses data is disabled or set to manual. Wifi is disabled, GPS is disabled, Bluetooth disabled. Google/Facebook sync is disabled. No Live Wallpaper, Email is set to NEVER, Fancy Widgets is set to NEVER. Reset the battery state in recovery numerous times, wiped cache etc.
Last night phone was at 60% when i woke up the phone was at 35% and that's only about 10 hours and after a FRESH shutdown and reboot. So nothing out of the ordinary like a game was running.
Whats Running after a fresh boot is in the pictures below, ending things like Tango and Galley, Facebook make no difference.
What is causing this massive idle drain?
If i need to do a full wipe is there a way to save my games saves? don't care for anything else just dont wanna start angry birds over again for a 3rd time.

You got 2 days before??
I've always only ever gotten max 12-14 hours out of my battery. Wifi off, bluetooth off, gps off, 3g on, background data & auto-sync on for: 2 gmail accounts + facebook (no auto refresh) + twitter (updates ever 30 mins) + whatsapp. BeejiveIM, GoSMS, Lookout, weatherbug elite widget (updates every 12 hours), agenda widget, NoLED on, and go launcher ex. Running stock rom JL2. Drains about 15% overnight (7 hours).
Not sure how you got 2 days before, but sounds about right to me that you get less than 24 hours from your battery.

Myself and many others get 2 days with light-moderate usage. I'm on 2 days 9 hrs and 10% left right now with 2 hrs 15 min screen time.
If you can't figure it out you might just have to bite the bullet and wipe it to see if that works.

Did you try this:

yes i did try that, its annoying the hell outta me that it used to last 2 days but now its like this and thats with everything off.
I used to have a live wallpaper on all the time and yes that did drain the battery allot but i would still have about 30% after a full day of usage from a full change.
Now it dose not matter what i change if i live wallpaper or not its still dies about 3PM
any way to save my games says if i have to do a wipe?

That's awesome! I get 8% an hour drain on idle with 2 gmail accounts, and a few apps synching... with usage (bluetooth music, browsing, texting...) I have about 15% an hour drain.
Wiping, battery stats wipe, new roms, kernels, and modems don't fix anything... I guess we just have to accept that some units go through more battery than others!

If you're using Google Latitude service (configured via Maps), try signing out of it and see what it does for you. I've been suffering from excessive battery drain as well and after a lot of experimenting I've found out that using Latitude on Froyo ROMs (any Froyo) leads to phone not entering sleep mode properly for some reason and therefore draining battery a lot.
Nexus S users are experiencing this as well and I've even had confirmations from Desire users experiencing this, so this might be some bigger issue not related to SGS.

There's all the standard stuff running, gmail, swype, social hub, task manager, some other widgets, etc... There's no talk time on this run, it can burn it up pretty quick probably 20+% per hour.

No, no Latitude.
The display will suck up 90+% if you're using the phone alot since it burns battery much faster than idle or networks.

Interesting, I'm going to give it a go without Latitude on after I reflash stock JL2. My "Time on" for Display is usually something like 40mins or so when I check it at 98%

Idle drain seems to be what are most worried about.
Ok first fix permissions from cwmedia recovery in speedmod.
Then wipe cache and dalvik partitions, don't worry your phone will rebuild them.
Next I would try something if you want avoid a factory wipe.
Disable swype and clear app data then re-enable. Swype seems to have non wipe issues thru kies.
Now use OS monitor app to find apps which lurk in the background and then check their permissions, ones that can keep the phone awake are the culprits. Wipe their data or uninstall.
Facebook app sometimes doesn't shut down properly so watch that.
Also after a session I like to use clear mem level2 to stop Facebook or another app eating battery.
Finally what modem are you using? Jpy modem sucks for me at least. The latest jve from the gingerbread leaked rom is superb!
Hope this helps and good luck!
Stock JPY, Insanity SpeedMod OC-1200Mhz/UV, ext4, JVE gingerbread Modem,

Something I did a while ago seemed to help.
I ran down the battery till it switched off. Phone wouldn't power on. I plugged in the charger and powered on again. To my surprise the battery showed about 25%. Unplugged the charger then used it again till shutdown. Took about half an hour to do so, even though it was only connected to charger for a minute or so. Did that about 5 or more times till finally booting up with charger connected showed 0%.
Generally it not a good idea to boot with the charger connected as it stuffs up the battery stats or something, but I think in some cases it can help. Charged it to full and had no problems since.
Obviously this wont help if something in the background is killing the battery.

May be you have a task killer running in background and killing tasks that you shouldnt kill, by example any widget you have in your screen, it will cause that it will be reestarting and consuming CPU each certain time.

Remove TANGO !!! This soft was draining more than 25% overnight on my SGS (even if there's no service running and if it's not in task manager), After removing it, now my battery decreases 3-4% in 8h !

Funny Tango was the one thing that jumped out to me from the process list, but I don't have any experience with it myself. Shutting that off for a while is probably worth a shot.

This is my batterystats. "Taleanrop" is phonecalls or whatever the english term is.

Walk me through what you do to attain zero wakelocks please.

Juice defender, no juice defender, ATK, no ATK.
I get great battery, but betterbatterystats is still reporting wakelocks from google services and facebook.katana. Sync is on ONLY for facebook with 3 hour interval.
I used titanium backup to freeze:
-email
-gmail
-maps
-kies
-talk

You will never have zero wakelocks, as they are how the OS works.
If you have apps keeping a wakelock longer than they should, or when the screen is off you have a problem.
Also check the graph in settings > about phone > battery, if the awake and screen on lines line up apart from where you may have been downloading stuff, talking on the phone, listening to music, anything else where it would make sense for the phone to stay awake when the screen is off, then you are ok.

oh the phone sleeps perfectly, I just thought there was room for improvement what with 2 minor wakelocks. just a junkie for tweaking .
I un froze everything gonna scope out the batt life with no power saving apps/features.
[edit]Success! I got around to freezing some more .apk's with Titanium as per https://spreadsheets.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0Ag43oj7rLQP4dENZcmhGN0ZUa3pHSENVeXlqUm5vV0E&single=true&gid=0&output=html
and I'm getting 1mA power draw in idle/sleep according to BetterBatteryStats. Before I froze a few extra apps my best was 20 mA in idle.

you want zero wakelocks? buy a nokia 3410. As mentioned its excessive wakelocks you should worry about. Zero wakelocks means no point having these type of phones as you wont be using any of its features.

A logical step would be to actually use the phone for a week or two and monitor the wake locks in conjunction with what you are using on the phone .
jje

The easiest way to do this - completely serious - is to just shut the phone off when you're not using it.
When you want to use the phone, you need to wait for it to boot up. That's one button and 30 seconds or so.
To freeze and unfreeze apps as you need them will take just as long, be MUCH more tedious, and still drain more battery while the phone is in sleep mode.

booting the phone drains a fair chunk of battery though (at least on my previous 2 phones)

Massive battery drain

Hey guys. Recently my battery has been dying at an alarming rate. According to BBS it's from a process called diagnostics.client.Wakelock, does anyone have an idea what could be causing this?
I started noticing the drain after setting up my Galaxy Gear, don't know if that may have something to do with it.
Thanks!

I am facing a huge battery drain as well after the recent update was pushed. I don't have the "diagnostics.client.Wakelock" in BBS but Samsung Push Service was hogging a lot so I turned that off. It was 80% at 11PM and today morning it was down to 59% .. that's 21% in standby mode. Is it not going into sleep mode or is something else causing this? I have almost everything turned off. Any ideas guys? Thank you.

MJ7? (not sure why but like other people remarked - the battery life looks to have somewhat declined - 30-60% less?)

Yes MJ7. I hope this is a bug that can get fixed sooner than later. It's horrible. I just got 1h 37mins of screen time and now I am down to 12%. Just a few calls and some Instagram. Nothing else. Would removing the battery for a while or something help? I haven't installed any app since updating to MJ7 (2 days ago).

I've had this issue with MI7 and MJ7 so the update is not the problem. My guess is me freezing most of the samsung bloat on the phone through Titanium is causing this. Maybe there's a process trying to find something thay I froze?
Sent from my SAMSUNG-SM-N900A using Tapatalk

I fixed it by charging my battery up to 90% then removed the battery and kept it aside for a while ~10 mins and then plugged it back in and charged it to 100%. Now it seems to be normal again. No drain last night. Moved only 1% from 12AM to 9PM. Cheers!

I have the same issue with MJ7 firmware; the phone sometimes doesn't get into deep sleep while the screen is off.
A possible cause of the issue: switch off wifi when data are off.
So now I switch data on before turning wifi off.

Anyone ever find a solution to this? It's killing me.

Same here, my battery declines almos 1% every 5 minutes just texting via Whatsapp and I know Whatsapp is not the guilty. Using Wakelock monitor shows 30% Android System usage with a lot of entries in Gpslocationprovider (even with GPS off and everything on Location settings off), SyncloopWakelock and AlarmManager... MJ7 here too... My Note2 wasn't like this... I finished the day with 5% of baterry after heavy use from 8am til 10pm (including 45' watching videos)... With my Note3 at mid-day I have my battery death!! I can't believe it! and I don't know what is happening (I only have 4 days with my new Note 3) and I have tried almost everything (deactivating) except wipe data/factory reset (I've tried soft reset and nothing)

Anyone ever find a solution to this wakelock?

anyone find a solution?

I noted that my GN3 would have great and then poor battery drainage. It seemed to happen right after my first long call of the day. I noted in my wakelock app that diagnostics.client.wakelock was using a lot of time.
I decided to take more drastic action by doing a factory reset and restoring apps one by one. I first used Kingo Root to root my GN3. I had to uninstall Kies and the Samsung driver to get the rooting to work.
Then I backed up with Helium and Titanium backup.
After a factory reset, my battery usage was about 0.2 percent per hour. I use only data and no wifi.
I have now restored most of my apps and still have 0.3 percent per hour usage. I have not updated any Samsung or ATT apps.except for ATT code scanner. i have not "used" any of the google apps except for gmail, search, google+ (signed out). Google music is turned off.
Diagnostics.client.wakelock still shows up but with low time now.
After twelve hours, the GN3 is at 96 percent including a two minute phone call and email updates.
------
After a long phone call, I once again saw my battery usage increase and stay up after the phone call.
-----
I re-started with a factory reset and only restored the minimum apps that I use to browse, email, text, phone, and backup.
So far it is performing well in battery usage.
I will be adding more apps until I find the one that breaks the good performance.
-----
So far I have been able to make it through 24 hours using only TEN percent battery usage. I have added TextPlus, BofA, drippler, Helium, Titanium Backup Pro, CPU Spy Plus, Wakelock Detector, System Tuner Pro, Battery Monitor Pro, AutoBluetooth, Maps, Youtube, YP, Total Commander, Visual Voicemail, Quick Boot, Root Checker, Turn Off Screen. Everything else is stock without updating AT&T apps or Samsung apps.
I am seeing an idle usage of less than 0.3% and that is with two widgets for Battery Monitor and System Tuner. They and Textplus use up the most power. I also talked on the phone via bluetooth for about 30 minutes.
I still get the diagnostic.client.wakelog but only getting about 5 percent awake time.
-----
I did another factory reset. This time I did not allow any app updates.
I installed Titanium Backup, CPU Spy Plus, Wakelock Detector, Battery Monitor Widget Pro.
I have not seen a diagnostic.client.wakelock at all after one hour of use.
-----
I added TextPlus, System Tuner Pro. I put the widgets to System Tuner pro and Battery Monitor on the home screen.
I have not updated any apps since the reset.
I have counted about 7 diagnostic.client.wakelocks for a total of 4 seconds of wake time. My wake time percentage since yeaterday is around 1 percent.
I plan to update apps one at a time to see which one kills the battery usage with wake locks.

I just added AT&T Visual Voicemail, PayPal, BofA, and Evernote to my GN3.
The diagnostics.client.wakelock started climbing and keeping my phone from sleeping.
Uninstalling the four apps did not help.
I think that the problem is with the Visual Voicemail.
----
Factory reset my phone and am back to 1 percent wake state and very low battery drain.
----
The cause of the bad wakelock was due to restoring APP+DATA in Titanium Backup. I did that to save setup steps.
I had restored BofA and Shazam with data and the wakelocks started up.
After I factory reset again, I installed apps the normal way and have been seeing a 0.3 percent use per hour.

Samsung's own software is most garbage in my opinion.
If you use ChatOn and Samsung Hub, etc, disabling this may have an impact.
Here's how I've solved the problem with this pig of an app.
1) go to application manager under settings.
2) go to the "ALL" tab
3) find that "samsung push service"
4) uninstall - this will only uninstall the updates. Once all the very useful updates are gone, the option changes to disable.
5) disable and good riddance.
On a side note, search for this on the playstore. the reviews are hilarious.
c.

Nothing I had tried up to today has fixed my battery drain and diagnostics.client.wakelock issue.
However, today, I got a software update OTA (nb4) on my phone and it appears the problem is fixed.

Hello everyone, two days ago i downgrade to kitkat, I decide to re-put Lollipop because I'm documenting on various forums Italian and foreign, and this drain the battery does not have all .... well for my case I installed the GSAM Battery Monitor from Play Store that seems to work well with Lollipop. I left the phone idle and discovered that the deep sleep has never been reached. The phone was always active, even when locked.
GSAM has reported that the app "Unified Daemon (EUR)" was among the top three applications that consume battery.
According to various forums is a preloaded application from Samsung that unifies information like weather across other applications preloaded. I really do not know what good has this application.
I tried to turn it off, and in fact the phone goes into deep sleep with consequent consumption "standard" like KitKat.
The downside of disabling this app is that you lose the weather from the lock screen and through the window of the cover S-view, while the widget on the home seems to work perfectly.
Obviously there is to say that others should do the same test and see if this app will appear among the first applications to battery consumption.
A greeting

disable Facebook app (use web version) and turn off wifi when not being used. My battery usage has transformed! See other thread....70% after 10 hours. 56% after 13 hrs! Lollipop is buggy. Manage wifi manually and you're battery will be awesome.

^^^^this^^^^ . Me too. Disabled damn Facebook and it a few Google apps and I'm back to normal. The main culprit is the stupid Facebook. To make easy access of it from Web just make a shortcut on your desktop.

I will leave wifi on today regardless of whether or not it is connected and see if things get warm / battery usage ramps up. If it doesn't it might indicate an issue with FB alone or at least prove whether or not wifi is stopping the phone from going into deep sleep after a period of non use. Yesterday having left FB and wifi off, resulted in 40% battery remaining after 16 hrs usage. It never got hot once. This is my yard stick.
Lots of users are having issues with the latest update to facebook - just look at the comments on the play store!
Anyone else been having high battery usage but are not users of FB app on lollipop?

@gasland Here is what i did.
I uninstalled
Facebook, Facebook pages, Facebook messenger and com.facebok."something"....
I removed everything that had the name "facebook" and rebooted my device.
Battery has been okay since then.
Ps: I also froze "unified demon" as I don't use either of the weather services or finances or all that crap.
