I've had my S4 for a few days now. For the first few days the battery life has been great, but now it seems to be depleting faster and faster, with "Android System" as the main culprit, usually taking over 70% of the battery used.
Anyone have any ideas as to why this could be? It's overtaking any idle processes and draining the battery even when the phone isn't being used at all.

People seem to have linked high Android System battery use with having certain samsung features enabled usually. Such as the eye tracker, etc. Do you have many of those features turned on?

Hi Everyone,
I know there are thousands of threads regarding battery consumption on the SGII - I have tried many many suggestions and I still have terrible battery life. I was hoping someone could give me a hand in analyzing if my stats are normal or if there is anything I could do to make it last longer - my battery life is just terrible.
I'm running RootBox 3.2 Jelly Bean.
Please find attached my BBS and Battery graphic. Let me know if there is any other detail that I can attach in order to troubleshoot my battery consumption.
Thanks a lot in advance!
Try using 2G networks when you don't need big bandwith. 2G is enough for WhatsApp, WAP sites, messengers.

I have tried being on 2G the whole day with very similar results
Disable all data connections for a while and compare how much battery was used.
Try GetRIL to get a match baseband and see if it improve it.

Your log is not looking that bad considering your screen on time of about 2 hours and the CPU usage.
The cause of the largest wakelocks seem to be your music player and synchronization software. Maybe you could get less wakelocks by reconfiguring them.

So you are saying 2 hours of screen on time draining over 70% of my battery is decent? Not sure how much its supposed to give

No, this is not what I'm saying.
First the battery draining is not over 70%, it is 64% (according to what your BBS log says). Second, the amount of time the phone spends running with a 'high' CPU frequency is quite large, or, in other words, the amount of time your phone runs at 'low' CPU frequencies or even better, is in deep sleep, is quite small.
Taking all this together I think you do not have abnormal or excessive battery draining.
This is my battery stats for today's use. How is it? Thanks.

In order to get an accurate response, you'd need to post more screenshots from BBS - things like wakelocks, kernel wakelocks and app activity will help greatly to diagnose your phones battery consumption.
By the looks of the 1 screenshot that you have provided, I can only assume that you are a pretty heavy user...as the device did not have much deep sleep time (only 25%) and the battery per hour rate is 7.2% .

Yes I use my phone a lot during the day. Next time I will do a 100% to 1% and post more shots.
I updated my op with more information. How is it now?

Looks decent to me. Not bad at all for such heavy use
BBS Review
Here is my dump. How is my usage? Is 12.5 hrs till 4 percent good or bad? Note that the awake time is higher because I was listening to music with the screen off. Don't refer me to the BBS thread because my idle battery life is great. Thanks again!

You need to actually read the BBS thread..
If your idle battery life is "great" then it boils down to how you are using your phone. Are you letting it sleep or are you using it a lot?
Getting rid of GoChat will improve your battery life as it is creating a wakelock.
You will gain still more battery life by going into Settings->Sound and unchecking all the boxes towards the bottom. This is yet another known issue..
Looks like you are using it a lot, and getting the battery life associated with a heavy user.
Do you have a more specific question? I'm not sure what you are looking for here really. The main thing you need to do is research this stuff so that you are familiar with it.

I read the BBS thread and have already posted an idle log there. I only posted a log instead of a screenshot cuz I was lazy and didn't feel like taking 5 screenshots. The time that the wakelock was on was the amount of time I used GoChat, meaning the screen was on as long as I was using it. I just wanted a yay or nay of my battery life. I usually play videos from youtube for a solid hour, browse the web intensively, take a couple of photos, use 3g, and send some texts, if that helps in putting a figure on my battery usage from the screen on time vs the deep sleep time, so thanks for answering my question.
Hi,
I would like to ask for some help regarding battery drain. Im currently using S3 with CM10.1 and the battery drain is quite high.
Using BBS, i have gathered some stats and i would like to request for some help in analysing it.
I see that multipdp is taking up a huge chunk of the kernel wakelock. my signal strength is at -85 mostly.
In the battery stats, it also shows that android OS is taking more than 50% of battery, that's unusual right?
Any advice would be greatly appreciated!
Hi,
Any help please?
Really need help! Appreciated thanks!

all the cm roms have the problem of battery drain. i get around 15 hours on a normal usage and around 10 hours with a little bit more usage. try changing the kernels.
:good:
Cyanogen mod roms are known to drain battery much faster than touchwiz.so you cant really expect the battery life to be the same as on stock or stock based roms. you may improve the battery life by using an app called Greenify. it hibernates apps so that they will not run in the backround. this can help considerably. also make sure to turn off gps , bluetooth, wifi. and mobile data when not in use. also battery should improve after three charging cycles

Do not bump before 24 hours of inactivity on the thread. It is against the rules that you agreed upon when signing up for this forum.
CM doesn't have the best battery life, I see some Facebook related things. Facebook is a known battery drainer. Their app coding is atrocious.
Sent from my GT-I9300 using XDA Premium 4 mobile app
Thanks for all the feedback. I accept that CM can drain more battery than stock.
What im quite bemused by is from seeing how other people's battery usage do not have the OS taking more than 50% but mine in fact does.
I just have a feeling that's unusual?
Sorry for not abiding by the rules, my anxiousness to find a solution :crying:
Just read the ten million identical help battery drain posts for clues .

I have lately installed RR on my S3 and facing battery drain issue, It has gone from 100% to 1% after only 20 hours with only 2 hours SOT (30 min youtube and 1.5 hour surfing FB over wifi) below battery stats screen shots.
I've never used an i9300 but still use an i9305. Just by your description and the screenshots, my initial assumption is that your battery is dying or nearly dead. I doubt there's still a production line open for i9300/9305 batteries but even a new (mature) original Samsung battery might revive your device.
SOT is clearly pretty personally driven and not only depends on the used applications but also settings, network connections etc. and thus difficult to assess from anybody else but the user. However, you might want to consider to take a BetterBatteryStats (BBS) "idle dump" and to post that in the BBS thread.

I have already purchased a new battery and this stats using new battery.
Had this issue across many phones and Android versions (including my current Pixel 3a XL on Android 10, unrooted) so posting here.
After a reboot I see overnight battery drop as low as 0.1/0.2% per hr, which is great. After a day or two it climbs to up to 1%/hr over night (though normally lower).
I've tried force closing most of my apps, and clearing them from recent apps before I go to sleep, and NOT doing so, even just before the reboot - it doesn't seem to make any difference - after the reboot battery drops little over night getting worse over time. The odd thing is the low over night consumption can occur even if I've been using the phone (and apps) for a little while before the first night. Have also experimented with Naptime, which hasn't helped other than to reduce the %'s overall a bit. It's as if there's something driving this behaviour burried in the OS maybe to do with the cellular radio? But as I said, had this issue across several phones and Android versions
Other folk see this behaviour? Any idea what causes it?
Anyone?

May be the better place for this question is the BetterBatteryStats (BBS) thread on XDA. Search for it, read the first couple of posts on how to produce an idle dump, install the app, take the dump and post it in that thread. Take the dump on the day when you think the drain is more. Not on the first day after a reboot when the drain is very low.
