Hi , I saw all screenshot of battery life here in XDA Forums and i saw that everyone has its android system under 10%.. But mine is different, my android system is over 20% all the time, in this screenshot it's 23, but most of the time it's about 25-30%.. However my "Android OS" is 12%
Look at the attachments
My question is, is that normal that android system is over 20% and Android OS is about 12% ?
If it's not how to fix it ?
Edit : Sorry i forget to say that i'm on stock 4.1.2 ELL4 , stock kernel too

Hiya.
On my phone Android system uses about 15%. I just compared our numbers and everything is pretty similar except for the send data. Yours has about 10 times as much so I would say that is weird.
But that is where my expertise ends so I will patiently wait with you for a real guru to chime in.
Hope it gets sorted out!
Cheers. :good:
Yeah that sound very weird that it use so much data and is that high .. it never goes below 20% ..
Anyway thanks for you answer, i'll wait for someone who can clarify this
After trying for several months Android 4.1.2 official, I decided to go back to version 4.0.4 is the cause of the battery that doubles in the case of ICS, the aesthetic advantages Jelly Bean does not cover the disadvantages in battery life.

I don't want to go argue about the definition of "cheating", nor will I tell you that you are wrong about the counter resetting (though I'm almost sure you are) but you definitely DID recharge (and don't try to deny it because the proof is IN your screenshot )
Great thread

Is a fact that the battery lasts half that Jelly Bean with ICS, Samsung has not yet solved the problem...

I had battery drain problem with 4.1.2, my phone would last only some 30h. Now I flashed XWLSJ and I only had to charge after 3 days 15h (still had 7%) and this is in par with what I was getting with 4.0.3. My friend who flashed XWLSJ confirmed huge battery life improvement too.

4.1.2 is not so draining battery…at least i slimmed Svoice and google map(i don't need these),turn off weather widget and lockscreen weather can use over 5 days…personnally google map has a unit that always at backstage and often wake the phone…but the weather is most draining battery!only off the lockscreen weather can enlarge your battery over 25%…widget is same…so i usually on the weather only when i want to know how the weather is…
sorry for my poor english…
loving this thread....... i carry a small nuclear power pack in my pocket (My sex life is over but it glows in the dark now ) And i get 12.2 million years battery life out of mine. (Its that old my dad had it first )
really anything in the order of 10+ hours (ish) depending on if you use your phone or look at it lovingly on your desk is more than reasonable.
Be happy xda'ers
I know this probably isn't the best place to ask this, but my other half's S2 has just been updated to stock 4.1.2 and she is getting horrendous battery drain.
The phone is fully stock (never been rooted, no custom recovery etc), is there anyway she can downgrade back to 4.0.4 without losing all of her apps & personal data?
I don't really have any experience with Samsung phones, I am a Nexus user so I do have a usable knowledge of Android & hacking.
Thanks in Advance

I have to agree with the battery difference on JB..
On average I get around 3 hours screen on time, on ICS I get around 4.5.
No shocker as it's pretty much in the beta stages.
Definitely switching to ICS, until a final 4.1.2 is released.

oh really that means I should be getting better because I am on 2000mah but it seems not. Im not sure what's the problem if its the battery or the kernel. I also used an ICS firmware from Samsung I9100TDULP4. I don't know if that affects the battery life

Well I dont know if it is properly calibrated. By the way I got this unit from my uncle so I am not really sure if the battery is still good. How do we know if its still good. I dont know how old is this battery. How do we calibrate the battery and does the room affect this battery life?

right now I am using the original 1650 mah stock battery of s2. I've been doing a lot of file transfers as of this moment via e.s. file explorer and currently I am transferring almost 13gb of data via wifi from my laptop. its been awake for 4 hours now with screen time of 1 hour and 30min. e.s. file explorer is keeping the system awake for 3 hours. I did some facebook and viber chats. screen at 35% brightness.. do you think this is the expected life of the stock battery? I am fairly new to samsung and I found the battery life to be disappointing even with the stock jelly bean rom from samsung. I will post some pics of the battery stats and cpu stats from cpu spy. another thing though. is there a good app from the market where I can test my two batteries and compare them? thank you

To callibrate battery..first completely drain the battery to about 5%, then charge the phone non stop without disturbing it till 100% and immediately remove the charger..again fully drain the battery and follow the above steps and u will get better battery life after a few cycles!
About roms..battery life does differ from rom to rom...i suggest u could check the custom kernels packed with zzmoove governor, ithat particular governor definitely improves the battery backup!
And in the above post es file explorer is eating ur battery..for that u should download greenify and hibernate apps continuously running in background!
great. I will follow your steps. one more thing. how can I know if the battery is still good or if its still holding the proper charge its suppose to have? thanks

best I can get is about 3 days standby in jb stock.
I use the 2000mAh battery is primary battery.. no big surprise to expect here, capacity is just 21% more by construction...
With wifi on, JB burns in my case about 3% in IDLE.. stock kernel.. and about 5% in 3G mode, IDLE.. then battery drains more or less fast depending on screen on, phone calls etc. I use the phone extensively for work (email sync & replies, phone calls, sms and voip) and i have to topup the battery twice or trice a day!
Have tried various custom kernels with all sort of magic to reduce battery drain.. more or less effectively.. sometimes with less stability.
Right now trying out latest dorimanx 8.27.. seems thatn IDLE with WIFI on drains around 2% per hour.. better than stock.. still not quite awesome
I miss the GB battery life.. but JB is so beautiful in comparison, I cannot go back!

Does Jb stock for you has better life or does custom rom have more? I really like the custom roms but as per observation stock rom offers more battery time. Right now I just reverted to stock rom i9100xwlss. Touchwiz really sucks. Supernexus is really beautiful but offers less battery (but I will have to try yet their latest build). Also one of the reasons for going back to stock is the camera shot quality. Custom roms really have poor camera quality. I guess when it comes to lowlight shots the stock roms are best. So much for that. Does stock rom offer more battry for you or custom rom does?

Below is a reply in some other forum by Samsung offcials regarding a specific method to Hard-Reboot your phone after a Firmware update: This method particularly helped me improve the battery life on SGS2 after 4.1.2 update.
"1. I’m sorry you are having issues with your device after upgrading the firmware. I can understand your frustration about this.
Old systems settings can be left on the phone after an update occurs, which is why we usually recommend a full factory reset after updating. If this isn’t done your device may begin to give false readings from system resources, or experience technical problems, which may explain the issue you are having.
We would advise on doing the following, which is designed to reset the settings on your device. Please back up your device using Samsung KIES before you do this.
1) Remove the battery for at least 40 minutes, put the battery back in and allow it to fully discharge. Afterwards, perform a full battery charge with the device turned off. Do not interrupt the charging process.
2) After the battery is fully charged, we would like you to perform a full factory reset, which can be done via Settings > Backup > Reset.
This process will reset your device, remove old system files that are no longer needed and enable your device to operate normally again.
Please let us know if your device continues to experience problems after the reset so we can investigate further.
If you require any further assistance, please contact Samsung again and we will be more than happy to help.
Kind regards,
Stewart

Actually I only use stock JB.. and trying to get it last longer with some custom kernels.. recently trying snapdragon rom, which is stock JB as well but with some S4 apk made compatible with S2... tried some time back omega, vanila rootbox and some other android builds for s2.. but was facing few stability issues / bugs and also missed some features that i was getting from stock rom.. so i gave up with these... now just aiming at stability and if possible battery endurance.. but not at the cost of stability.
well i just get the OTA kk update notification

Not my findings at all - any of them. Perhaps you should venture in to the Android Development (802) forum... you could provide a more accurate response then...
For me, on the D802, battery life has gotten better. Especially idle/sleep seems better.

Tried out the G Pro 2 Kitkat port and OMG! Rock stable and battery life... I have no words to describe how good it is. I'm getting up to 10 hours of screen time, 4 hours of music and still have 18% left for reserve. One thing I've noticed on KK is that screen brightness has increased. 40% brightness on KK would be equivalent to 55% in the earlier version but with better consumption and idle. I went to bed with 91% battery and woke up 9 hours later with only 2% lost.
Hello,
is it just me or the battery on April's update drains a lot quicker than any previous updates?
I am currently using PureNexus 23/4 clean flash no mods and the battery is draining like crazy when playing some games or using it in general.
I know it depends on how are you using the phone, but this month is draining a bit faster than normally does.
I've used various ROMs with the April's update and are all the same.
I'm getting good battery life on latest DU.

i have the same feeling too..im on stock rom..i was getting between 4.5 to 5 hr sot most of the time, after aprils update getting only 4 hr.

Not on stock with EX Kernel. Check your battery capacity.
Not familiar with the Pure Nexus kernel. You might want to install a kernel auditor program like Ex Kernel Manager and check what your current kernel settings are. They could be set at a more performance oriented profile that eats battery faster. Since Pure Nexus is an Aosp Rom with its own kernel your experience on Pure Nexus wouldn't be applicable to people on other Roms. The best place to post your question would really be the Pure Nexus support thread.
LOL this question pops up after every update

Every single time people say their battery life decreases. Without fail. Im surprised by now their phone can even still hold charge since they say it drops with every update
I have a problem after that update. My 6p is stock and come after the beta 7.1.2, I full reset to factory and the drain is still here. Before if I left the phone overnight it drain 2-3% in 5h. Now it drain 13/15% ore more... And the battery interface doesn't report a specific app or internal process.

Check your battery capacity with Accubattery just to be sure it's not battery degradation, and install BBS or GSam to identify a wakelock, process or app sapping the battery.
Ok, thanks. I've installed Accu and gsam. I will see.
