Yes, I think it is pretty normal unless you find that your battery drains too fast. Let's say you have an app like Reddit sync taking 70% and android system taking 20%, than you'd say that Reddit sync is draining your battery. But if nothing else drains your battery, then it has to be android system that uses the energy coming out of your battery. Afterall, your phone is On and thus, the system needs to fonction to keep it going. Thus, I would say that optimizing your phone so as to have Android system using as much as possible, in percentage, would be ideal.

Fair enough, thanks

Indepth battery usage stats?

Is there an app that dispays what's actually draining the battery?
My cappy seems to randomly drain fairly steadily and quickly some days but not others with the same type of usage so I want to find out exactly whats happening.
Im currently using watchdog and systempanel but neither really show what's going on.

Hi, Nooby question coming up.
recently rooted my SGS2 using the Chainfire Kernel and now have noticed that Android OS is prominent in my battery usage, sometimes around 50%in an hour,
Is this normal?
I also run a HTC IS stock and I have not yet seen ANdroid OS on the usage stats.
What is Android OS doing as I have also noticed Android System in the list at times?

Battery stats

Is this normal for our phone? I've been suffering from fast battery draining for some times.

obviously it's due to ROM i think? one is Sense 4.0 and another is Sense 4.1 though..
mine (viper ROM 2.5.3) with really heavy usage(screen never off), battery last for around 6-7hours..
What's your screen time, it looks like its behaving normally cause you've got a lot of screen on/offs and it wakes at the same time

What Rom Are You Using |?

Massive battery drain after JB update.

Hi,
I was so satisfied with how good battery lasts till JB update came. Before that I would rarely charge before night but now I have to do it every night I am sort of light to average user. My main concern brought this stats you can see screen shot where android system uses most of the battery. What is going onhhere? I have a few apps that using but not much changed in my habits. I am with 3UK

Did you do a full wipe after the update?
Yes I did. All from the scratch. I just red that one htc one owner had similar issue and his fast boot option was off he enabled it and things got way better. so was mine off just enabled it.
Why is everyone so surprised at Android System being at the top of the new battery stats?
It makes sense really. If you don't use your phone a lot, and nothing else is running taking up power, the system is going to be at the top...
As far as an actual drop in battery life, I'd download GSM battery monitor or Better Battery Stats and check for wakelocks.

Yeah I agree, especially if you reset your battery monitoring often, it can be highly confusing and misleading to read battery usage stats. I use Du Battery Monitor which I've been happy with.
I have wakelock detector installed. And also noticed android system wakelocks on cpu wakelocks are high on the high. Higher than anything else. And this happend in the first half an hour I am on the phone. First screenshot is cpu wakelock and second is wakelock triggers.
What would you guys advice to monitor for battery usage : over what time period and what to pay attention most. My wake lock detector is on now and I will do more screenshots tonight.

Well at least your phone is going into deep sleep and doesn't look like any rogue app. You may want to Greenify facebook though.
Also look here for a battery "calibration", some say it worked for them: http://forum.xda-developers.com/showpost.php?p=43579577&postcount=36105
And don't forget you need to let your battery "settle" which takes a couple of days.

How would you advice to tackle FB. It looks FB is persistent though on battery guru it's set to refresh it self ,,only when you open it,,
I will do factory reset again and then battery calibration later.

Use this https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en to hibernate FB when not in use.
EDIT: you have to have root

Why are there 3 battery guru icons in your bar? When I used it there was only 1. I got rid of it though after doing a custom ROM. Had no use for it.

Third one appears when low battery for extra savings. Second one I don't have a clue now. I normally have two icons.

Are your network location services on or off? If they are on, try turning them all off (as well as any Google Now network location service stuff). I found that sometimes the Google services updated badly and went into a situation where the battery would drain rapidly due to constant wakelocks.

I...don't think 16 hours is terrible considering that you seem to have been doing some Youtube and PDF-reading. The percentage on that PDF viewer seems pretty high but that doesn't necessarily mean anything. Facebook is obviously the biggest culprit remaining.
I would try to use Facebook in your browser instead of the app. I'm not a heavy Facebook user and don't need the notifications. It gave me a big battery boost after deinstalling the app. Facebook is constantly syncing and tracking your location, it's very batterie unfriendly

I have thought the same today to have FB on browser rather than app. It is strange I have tweaked FB app a lot like refresh only 4 hours, no notifications left on but app still awakening mad. Now only FB bothers me other apps behave well and I get pretty good battery consumption.

I am using ARHD 21.0 and it's got 4.3 in it. Android system reports it's taking up like 50 Percent of my battery but I still get more time out of my phone than I did when I was on 4.2.2.

Battery drain problem

Hi everyone.
For a long time I feel that my battery drains very fast.
I just use google chrome for about 15 minutes and my battery drains in 20%.
In addition, can you tell me what is the meaning of the numbers in the wakelock app?
Thanks.

Google services are the culprit based on those screens.
Probably location or sync
Is it possible??? :
Sent from my HTC One using xda app-developers app
Yeah, possible to the location. Mine also with the location. So I had it turned of in Apps&Sync google setting. Then i can say it did help my battery to survive few more hours. :laugh:
The location services were disabled all this time.

For the drain you can monitor which program keep your CPU wake with wakelock detector.
And what about the usagr details error?

don't think theres anything wrong with your phone. The usage screen shows two things: app usage and other usage, afaik the app usage only shows how much of the battery is used by different apps (android system, viber, youtube, etc) and other usage shows usage related to network, and since youre in airplane mode, it doesnt have anything to show under that category.
Try using a couple of other apps, such as youtube or music for 15 minutes, im sure theyll show up under the app usage after that. And also take your phone off airplane mode, and im pretty sure after a couple of hours the other usage category will have things such as "phone idle" or "cell standby"
