hello everybody
after upgrading to 4.1.1 from my provider, the battery life seems to have decreased a lot
in battery status, majority of power drain comes from android system, which i dont think is normal
has anyone observed a similar behaviour? just to know if is a problem of my phone or a problem of this sw release, before i roll back to 4.0.4
baseband version i9300budli1
kernel 3.0.31 256827
build jro03c.i9300xxdlih
thanks and regards
gm

I have the same problem as well so you are on the same boat as me
Stock JB uses more battery than stock ICS. It is a known issue
Not true. Your comment is not based on fact and is thus completely meaningless, so stop misleading people.
Provide evidence, based on which Stock ROM and kernel, your own sync settings, Apps used above Stock and Battery use with BBS log output.
And whether you wiped everything or not (as this is critical).
maybe not the right place where to ask, but is there a way to roll back to stock ics without having to reinstall all applications and data? as it has been possible to upgrade from 4.0.4 to 4.1.1 without losing user data.
havent found a way so far, i have all backups, but just in case i missed something...
thanks

ok was not so straightforward to find out but BBS should stand for betterbatterystats. installed and will look into logs
do you think that wiping everything out and installing a fresh 4.1.1 would solve the issue?

Doing a clean install is the first stop, then go through all your settings and check what you have enabled by default.
Also Google now uses a bit of battery due to location services, but imho it's worth it!
havent changed any setting after upgrade. afaik, google now is not enabled, and all location services are currently disabled.
still battery like sucks. one day with very scarce use of data and voice.

Wipe the lot format sdcard.
Install rom only .
Turn everything off sync wifi gps .
Charge fully and leave for about twelve hours .
Check drain it should be between 2 and 5 percent .
After adding back apps you will probably find a far higher drain = your apps not the firmware .
jje
Should be getting something like this... light use, hourly syncing etc. So about -2%/hr
JB UK (BTU) Stock rooted.
Note that it is important to charge to 100% (not 99%) at least once some time after flashing to reset the fuel gauge correctly. The battery performance (or more accurately the battery monitoring) improves over the first few days of normal use/charging.
I tested both stock ics and stock jb. And stock ics has a better battery life for me... btw if you turn off all motions and extras like smart stay you should get better battery life.
I theory jb should have better battery life than ics but I didn't noticed that.
P.s. I will post bbs stats next time i flash stock rom (probably not so soon )
If I have misleaded someone I'm sorry

Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!
Go back to GB with speedmod kernel is an option.

Is your device rooted?
If yes then switch your kernel to apolo it's gives you good battery life

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.
Battery Drainage is very common in JB Stock

Hey Kaigo ,
I have faced the same problem as you have faced ... Gone through a lot of problems to fix this Many of the Stock JB's for GS2 are having a lot of issues with the battery drainage
Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.
Hi everyone!
Some days ago I bought a new battery for my S3 (seller said to be genuine) and I am disappointed because its performance is almost the same as the one I was experiencing with my old battery (18 month-old battery). For this reason, I have been researching and I have done this until now:
*) Being honest, this comparison is somehow subjective since apart from the battery change, my S3 was officially updated from 4.1 to 4.3 almost at the same time I changed the battery. Then, I wonder whether this update may have affected my diagnosis on the battery duration.
1) According to the point * I decided to do a battery calibration "without root" consisting in draining the battery to 0% and charging until 100%. I haven't seen any improvement doing this.
2) As consequence I analyzed wakelocks. I have addressed two of them from the System:
- AudioOutLock. to fix this one I did as recommended: disabling sounds when typing and all of this.
- Backup. Fixed by disabling the backup from Google (I would like to have it enabled but if it is causing a battery drain...)
3) I let the phone the whole night turned on with the 3g connection on and I got a ratio of 2%/hour draining. I have read this is more or less under the normal parameters.
After doing all of this I'm still not happy with the performance. Usually, my mobile gets under 20% by the end of the day with the screen on in a range between 1h30m and 2h. If I remember well at the very begging (when I bought my phone), I was getting my phone at 20% by the end of the day but having the screen on for 4h or more. After buying a new battery, I was expecting to return to that situation.
Do you have any hint? As for example a better way to calibrate? Factory reset may help? Should I check a specific wakelock?
Thank you very much in advance!
I forgot to mention that when I let it charging over night, my s3 does not always charge until 100. Sometimes it's until 98 or 95. I don't know if this helps you guys as a hint but I want to provide as much information as possible.
Thanks

Thanks!, I will check. But so far I have briefly seen it looks like there is not a specific solution more than disabling gNow and some other things. Maybe a good option is to downgrade or using a custom rom in which there aren't these problem.
its same to me.

Thanks!. I have been using Wakelock detector but I will try with this one. I was wondering if using this kind of applications for checking the wakelocks may provoke some battery drain itself. I mean, should it be used just for analyzing when you experience a battery issue? or should they be permanently installed no matter whether you have battery problems or not?

Hi, Better Battery Stats is using an already existing process of Android to obtain it's information, therefore the influence of the app itself on battery drain should be negligable.

Thanks for the info!. I have not seen anything special in the partial wakelocks. In the kernel wakelocks, it is difficult to distinguish whether one entry is specially problematic or not. After what I have read so far it may be the mix of social apps I have now installed:
- Whatsapp
- Twitter
- Messenger (FB messenger)
- Line
I guess maybe I have too many of them reason why the battery is draining more than normally when the screen is off

mk6 is fine with the battery...so firstly install an app called better battery stats search for it...install it and let the phone to be in standby mode for 4-5 hours..and then see in partial wakelocks and kernel wakelocks..and post those screenshots on bbs thread...someone will surely help you..
sometimes changing kernel could solve the problem..boeffla is the one i am satisfied with..and agni kernel is also one of the better kernels..:good:

Sorry for the delay to answer, I've been busy. Here I post the images of the battery stats. Sorry, they are not what you told me to be having them 5 hours quiet (that's difficult for me). However I can tell you that the 40minutes of screen on where just chatting on whatsapp or checking emails; no angry birds or need for speeds hehe... Are these images ok to be posted on the thread you told me? Thanks in advance!
I had a poor battery perfomance after upgrading from 4.1.2 to 4.3 until I've disabled fast dormancy. It seems that in v4.3 is enabled, and if your carrier doesn't support it, it will eat your battery. Donwload free from market "fast dormancy togle" by Siyah, and that's it

I have just rooted the phone and disable the fd. I hope this works!. Thank you very much for the info. However, now that I have it rooted, do you suggest to install a custom rom for getting a better performance? if so, which? there is a good one with 4.4 and multi-view?.
Thanks in advance!
Try flashing allblacksback mod it makes the whole system dark and saves battery on display and also I recommend disabling Google play services but this means there will be no push services but it saves a lot of ? ? ? ?

After giving a try to the idea of disconnecting the fast dormancy here I give you some reports on the battery consumption. I don't know why but statistics are wrong from the point of view of the duration (3 days).. since I disconnected it just 10 hours ago. I think its consumption is still huge. I hope you can give me a hint on it. Thanks!
Ive installed smartdroid. Battery perfomance seems quite better now! What do you think from the screens? However.. i find the screen too much consuming.... ive seen people managing 5 hours of screen in a day. Why i am not? May it be battery or configuration?
Thanks!
Do you have any hint on this? Ive seen that with the screen off the consumption is really good. However, with the screen on a doing normal stuff: chroming, feedlying or whatsapping it goes to a 20-25%/h.
Hi,
I have been using the same rom for one and a half year now(give or take a few months). Never had any issues, a few months ago I bought a new battery, I can easily go 26 hours with 1 charge, but since yesterday, something is draining my battery as if it's life depends on it.
I have not installed anything new for months.
The system feels sluggish, and the battery even depletes even when charging, and the phone is getting hot on random intervals.
Does anyone have any idea what is causing this or help identify this? I installed BetterBatteryStats, but I don't know what results I have to post.
I added some screenshots of the battery usage graph. Screen used to be at the top, and adroid system at the bottom(tell me if I have to translate them!).
I also disabled all the location services.
Thanks in advance.
Specs:
Android version: 4.0.3
Kernel version: 3.0.15-I9100XXLPS-CL294511 [email protected] #3

This is a rom I downloaded from here and it has root access.
Those battery usage screenshots don't really tell us anything useful.
Search for the BetterBatteryStats thread on here, post your logs from BBS to the thread, people who post to the thread regularly will be able to help you track down what's causing your drain (assuming it's something software/firmware related).

So, since I update the firmware last week on my SGP511 it has a huge battery drain!! on stand by with the stamina mode on it could easily last more than a day with no more than 5-10% depletion, but now it lost 15% in 7 hours. What happened? is there a way to fix this?
And it says that the main expender is the Android System..
please help..

If you are rooted, you can use GSAM Battery Monitor to check which app(s) create the wakelocks. Then deinstall this App or freeze it, e.g. with Titanium Backup.
If you want to switch off single wakelocks without deinstalling/freezing an app, you need the PAC ROM from the original Android development forum, I am not aware of a tool or Xposed-module which offers the same feature - but in case you find one let me know

No root on the tablet and not planning on it. the problem is that it was all fine before the update, it makes no sense that now I have start freezing apps and what not... is there a way to downgrade?

You have to root your phone in order to get meaningful battery statistics. If you don't want to root, you won't see the wakelocks which drain your battery.
Note that you can root without voiding your warranty.
Also I'd bet money that the OS itself is not the problem - more probably it is some app which was updated.
I once had huge battery drain because of the fingerprint-scanner wakelocks from Google+. Since my tablet does not even have a fingerprint scanner, I would never have thought this wakelock exists without GSAM Battery Monitor.
