"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!

Finally fixed my battery drain!! Turned out to be Yahoo Mail!!

I have been reading a lot at this and other forums trying to find out why my phone would drain 5-7% per hour with screen off even though after installing various combinations of custom roms and kernels and following suggestions made by other users such as monitoring partial wakelocks in BBS, freezing applications, undervolting, turning off sync etc.
Having spent many frustrating days on this I finally managed to locate the root of the problem and wanted to share this with other i9100 users and hopefully this helps someone out there.
What I noticed was that after installing a customised rom (i used checkrom, hyperdroid, villainrom) the battery drain would be <1% per hour and the screen on time closely matches the awake time. However, once I had restored all my apps using titanium backup, the battery drain would go back to 5-7% per hour. I checked BBS but there was no particular app showing which was causing partial wakelocks (except the usual alarmmanager, etc) so I always thought it was a rom/kernel problem and not an app problem BUT i was wrong, it was an app that was causing my battery drain (in my case it was the yahoo mail app) and for some reason it was not showing up in BBS as causing wakelocks but u knew it was chewing up my battery as the awake time kept on increasing while the screen on time was not. Now I am using k9 install of yahoo mail and battery life is great!
I found this out by simply doing the following:
(a) Install a custom rom and kernel (I used checkrom HD v4 and siyah 2.6.6)
(b) Turn off sync, notify new apps, google ad
(b) Install cpu spy and BBS
(c) Open cpu spy and reset times and then quickly exit the application and then press the power button.
(d) About 10 minutes later, turn on the phone and quickly check cpu spy. It should say that the phone was in deep sleep at least 9x%. Also check BBS, the wake on and screen on time should be very similar.
(e) Then install titianium backup and start restoring 5 applications (I chose 5 but you can choose more or less)
(f) Go back into cpu spy, reset times and then press the power button
(g) Repeat steps (d) to (f) until you find that the deep sleep % falls below the 9x% and then delete each of the recently restored apps and repeat the process till you get back to 9x% deep sleep.
(h) Hopefully you would have found the rogue app then its time to find an alternative app!
Hopefully this helps!

Weird yahoo mail doesn't seem to drain that much of my battery, but I'm not really sure as I change roms so often I have no idea what normal drain for LA2 is(probably 2mA). I did noticed that it almost never used 2mA with data on.

A suggestion for you since you don't seem to be aware of it.
You didn't have to look at it for days and days looking only at partial wakelocks pull down tab.
All you had to do, was to go to bed on a full charge, then read the text file that you can dump from that app.
It contains partial, kernel, alarm wakelocks and processes.

2mA is bogue, in fact, all mA reading is bogus.. it's an estimated value by an app calculated every 5 mins or whatever you have set at, unnecessary wakelocks justs so you can get some fairy/harry potter numbers.
Only way this could be true is if you wire a multimeter to it.

It may be bogus, but it still shows drain somehow. What other could I ever place on my 3rd screen without the big battery usage history?

I agree that yahoo apps are bad. At least when I bought the phone with stock 2.3.3 and installing yahoo mess & yahoo mail my battery drained very fast and I didn't know the cause. The phone stayed awake most of the time even if the screen was off.
I had a hunch that maybe one of the 2 yahoo apps caused this and uninstalled everything yahoo related. Since then, my battery life was great.

Yep....and most of the time there are better alternative apps....just need to look for them. The battery still drains fast when i am using it but at least when i am not using it (which from my usage history is about 60% of the time on a normal day) its taking just taking 1% per hour and allows me to survive till i am back home to charge for the next day!

I never use yahoo mail in my sgs2 but my battery drain as normal, so i think no reason to talk yahoo mail is the reason.

He is right. I had problems with yahoo mail too.
One thing I noticed is that even though it has sync it does not show up in bbs. I mean it has sync so it must be using some battery over time, but it does not show up at all in partial wake locks. It show that the system is not reading the drain by yahoo mail. Such kind of battery usage shows up as android os.

Just use gmail instead =]

Yahoo messenger is really bad, it does cause a lot of drain, it runs about 13 processes, whilst skype hardly runs 2 or 3. Disabled start up for yahoo messenger using startup manager and running processes by AutoRun Manager. Unless necessary I don't use yahoo messenger, skype only
Never used yahoo mail in my phone.

Yahoo mail and Facebook apps were draining my battery,just stop auto sync and it's fine. )

Mine crashed a lot while draining a ton of battery as well.I use k9 now.Problem solved.

Lollipop battery drain

I got the German 5.0.1
IS it only me or is it general with the battery drain?
Even in Flight Mode, I am losing the battery in a couple of hours

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.

App standby and Doze problem in M.M.

Hello:
App standby in developer option is showing all my app active, even the calculator, fm radio, adobe reader, it is supossed to inactive them if i don't use them and there is a lot of apps that i never used and they are "active". All my apps have set to optimize in battery and i was having better battery life in L.L.. Perphaps performance is a lot superior on marshmallow. In another hand, Doze is not working, my device idlle is eating 1% or more a hour.
Does anyone having this issue?
I have no autosync but notification on with whatsapp, badoo, happn, tinder, facebook, facebook messenger and precisition set to accurate. No games, just chrome an apps allready named. I am getting 12hs of baterry with 5-6 hs of Sot.
Now i have disable personal data on google play store, google play service and motocare in security.
Thanks in advance!

idle is draining more than 1% because when the device is idle the location services and fb notification services are still running in the background.

By default Doze doesn't kick in until your screen has been off for 30 minutes and then it checks to see if your phone is motionless - if it isn't (ie. it's in your pocket and you are walking around) then the 30 min timer kicks in again.
This is, btw, an absolutely over-simplified description. Basically if you are checking your phone every few minutes or walking around with it in your pocket, it's not going to Doze.
In your case, I wouldn't worry about what is active/inactive, instead I'd look at what wakelocks might be causing your battery drain. An app like "Wakelock Detector" or "Better Battery Stats" can tell you this but you have to be rooted.
Did your phone come with Lollipop and subsequently updated OTA to MM? If so, and you haven't done so already, a factory reset would probably help (or at least eliminate one possible battery drain cause).

You have Badoo, Facebook and Facbook messenger with location set to accurate + 5 hrs of SoT!!!!! 12 hours is a Miracle!!!!
What do you expect more? Sun, Moon and The stars?

Thanks all for your answers!
-Update via OTA, factory reset, wipe cache.
-Allready know how doze works, doing test in the nigth, phone on a desc, idle for like 9hs.
-Same apps than in L.L but worse battery. In L.L these apps didn't keep my device awake, now they do. Y checked and the one that make my device awake was Messenger. Uninstalled, tested and device didn't awake with screen off. Like 2 hours laters, same test, now facebook start keeping the device awake... I am checking manually because i didn't root it. I am trying too to see if this problem has to be with high presicition on location service or just facebool and messenger apps, but ****ing tinder don't work with battery saving ubication. I know all are ****ty apps but i love to **** strangers hahahahahhaha.
In the other hand, i had read that in nexus phone and other M.M phones in the developer options app didn't use figure "inactive", in my phone all apps are active and can't toogle to inactive!
Again, thanks a lot for your help!

Also, dissable a system app called motorols notification service, didn't know what it do but was with google play services an Dm services in not optimizing apps. Anyone now what it is? All functionality work the same!

Hi. Don't you have a problem with Facebook Messenger notifications? I set it to not optimize, but my messages are not received immediately. Sometimes even after 5 minutes after turning screen off I don't have notification and must turn screen on.

The Device Is Awake Too much (Too Many Wakelocks)

Hey guys,
i have too much wakelocks in my phone
i try to install franco kernel but it didnt help
today from the morning the device was awake for more that 2 hours (that the screen off)
my location scanning wifi and all that staff are off.
what can i do?
there are pictures of better battey stats.
and battery stats according to settings
thank you

Have to tried greenify and amplify? You most likely dont want to uninstall Facebook Snapchat Whatsapp and Instagram becuase those are all still installed. They will destroy your battery life. But If you greenify them, it wont be as bad for your battery.

i have greenigy that i put in there all my apps except whatsapp .
greenify supposed to make thos apps sleep and not awake the device right?
so maybe the drain is not from the apps because if it was because of they wil appear in the partial wakelocks

Up

Up

Have you tried uninstalling and reinstalling all your FB, WA and so forth apps? The stats look to me like lots of awake around screen on time and are perhaps down to multiple connections running wild syncing.
