I update my SGS2 in ICS Manually before two days... The ICS firmware is this : I9100XXLPQ .... But after i rooted and calibrate my battery with battery calibration apps from play store my phone battery start to drain very fast... For three hours it went from 100% to 40% with wifi,bluetooth ,gps,brightenes off ... I have just played a couple of games for about 10-15 minutes... i dont think that this is reason for 60% drain.. Plzz help me to fix my battery life..I cant do nothing cuz my battery go low very quickly...
Go back to GB OR

Dont expect a battery to recalibrate itself in two days no ap can recalibrate it requires use of the phone .

They are not hours..Just minutes... In 2-5 minutes the battery drain 2-5% ... (( if i use it for hours the battery drain completly..
I've had some success saving my battery by disabling Fast dormacy - Call *#9900# and disable.
I have found the battery life on ICS so far amazing
Use CPU spy from market. Take a look, for deep sleep doesn't work and also my phone was at 1200 mhz all the when was awake. Flashed siyah ics kernel and then it was fine.

Thank you so much, really help me, great thread
i think it is only kernel/change kernel and u solve the problem/
for me the best is cf-root
After full charge, if my mobile connect with WIFI it will give one day....or else, 1 and half day..

Ya and also it depends an kernal, am using Siyah kernal....its gvng gud battery life and smoothness, and much faster.
Om nom nom, battery *burp* But at least it's running on 200MHz and not 1200
Guess I might have to take another look at Siyah, and hope 3 is more stable than 2 was, kept having freezes with that one
After updating from official 2.3.6 XILA3 to 4.0.3 LP3 I expect a huge drop from <30 to about 10 then the phone die completly.
Attached battery graph.
This is the genuine 2000mah battery, and with GB 2.3.6 duration is about 3 days with GPS-3G.
i have migrated to ICS resurrection 1.1 from checkrom and find the battery life is better even though there is more stuff running in memory and more widgets.

Battery problem after updating I9100XXLPQ (ICS)
After updating to ICS try to switch on data connection, now try to switch on wifi.. it tries for some time and after 10 mins or so.. battery is completely drained out.
Is anyone facing the same problem ???
I haven't had the same experience as you but i have been very happy with Ressurection Remix 1.1. With the standard kernel it comes with.
I get around 1.5 days from a charge..... try it out.
Many talk about the Siyah kernel being good too, it has more options for battery saving/ performance.
Hope you figure it out

Hi there. I'm using GinTonic.SE v1.3 for 4 days now, and I can get only 30-34h worth of battery life - as long as I have Wi-fi and 3G off. I used to get almost 50h with Froyo CM6.
Has anyone experienced diminished battery life with GinTonic?
Thanks!
Gingerbread are battery drainers, try undervolting (settings/CyanogenMod/performance/cpu). And reduce backlight to minimum
i'm experiencing the same problem, the battery draining is anormal, i've tried with battery calibration but that doesn't resolve the issue, battery goes from 100% to 98 in about 1 minute (data,sync,wifi off and minimal brightness) then straight down... i need to charge the phone 3 times in a day, i had to reflash he cyanogen revolution... any advice?

It's true... as xxlordxx said... compared to Froyo, Gingerbread Customs are slightly higher battery drainers..... You atleast get 30 H, I used to get 13 with Gintonic..

have you tried the new GT 2.3.8? claims better battery use, i installed yday and it lasted for the day at least..but that was quite minimal use. as stated use either uv.ko or underclock with setcpu, i downloaded app called cpu spy it informs you what speed your proc is running at and u can get a decent reading on when and how long the speed is which helps in set cpu if you set up profiles so i.e when yr battery reaches x% the clockspeed will reduce, and choose a governer like powersave or conservative...it does make quite a difference
yes battery life is bad I will have to look at some of those 3rd party batteries
My Galaxy S2 is NTTdocomo from Japan, everything is working fine, apart from an extra battery that I bought recently. It is an original international Galaxy S2 battery, the problem is that it is draining very fast from 80% and downward, even while the phone is deepsleeping, but from 100%-80% the draining is quite normal compare to the original came with the phone. When I check the battery usage, the Android OS takes up to 45% of total battery usage, and the battery would drain from 100%-0% i around 6 hours with approximately 2 hours of screen on. While everything is normal with the original battery came with the phone, I cant understand why I have prob with the extra battery... Anyone knows why and how can I fix this prob? Thanks a lot in advance^^

Roms based on CM7.2 do drain battery massively compared to stock so going back to stock would help.
Battery callibration does not help - see Here
Same problem here... Living with it cuz stock has just become old and lazy
But if you really want battery switch to stock its way better than cm

There isn't a noticeable difference in both versions in terms of battery life. However, 5.7 has better performance and is noticeable.
You can try underclocking to something like 730 MHZ and save a decent amount of battery life without losing performance. Check this OC kernel out:
OC zImage
Also, use Cyanogenmod, ADW launcher without customizations is faster than the stock touch-wiz UI launcher.

For all those who r shouting that battery calibration doesnt improve battery.. Did the XDA said it improves battery life?? Do u ppl know wats the meaning of calibration?? Calibrating means adjusting something to the accurate value.. Not improving the value!! Even we never said it ll improve battery life.. Battery calibration just calibrates the reading to more accuarte one. So let the ppl calibrate it. Else leave. It ll automatically gets adjusted after 1 or 2 week.. U can see urself the change..

Yes, many members on XDA said that callibration improves battery life. The battery indicator on your status bar does not use batterystatus.bin. It does not automatically adjust after 1 week or 2. It re-calibrates every time you charge!
Read the article posted by XDA for more:

well i dont know about you all
but on my phone battery percantage isnt that accurate
cause when i unplug phone from charger and just open game or do something battery percantage goes to like 90%
but when my battery percantage is low like 18% it holds 30mins on 18%
I've tested many roms here and stock rod do tend to have better battery life, but... When i tested the RAZRv3 by TeamCooper, it had extremly good battery life.
When i got my Ace it had froyo, that lasted about 2.5-3 days. I upgraded to gingerbread official, battery lasted about 1.5-2 days on. Then i tried several custom stock roms and they all lasted about 1-2 days.
After that i started testing CM7 (both 7.1 and 7.2) roms and most of them lasted 12-18 hours (i used the wifi disables 3g function and some other tweaks to last the battery longer otherwise those roms would not have been usable)
Then i got to the RAZRv3 i used it for 2 weeks and the battery was amazing, it lasted easily for 3 days with no other tweaks than "wifi disables 3g" and also the performance was good. No lag!
Then i tested the CM7.2byFAT and the battery was awful but i really liked the rom so i keep 3g disabled when i dont use internet (all background apps use 2g internet) and now the battery last for 2 days.
As i've tested.... 3g takes really alot of battery in CM7 roms but in RAZRv3 (cm7.1 based) it worked like a charm.
So.. Everyone who wants really good battery life should test RAZRv3 that can be found here: http://forum.xda-developers.com/showthread.php?t=1478807
I have updated my S2 with the official ICS. My battery life is now so poor I struggle to get a full day's use. Before the update I would get about two days with moderate use.

try some batt monitoring apps from market and see whats draining ur batt and resolve the same either by force stopping those apps r deleting them if u find they r batt drainers
and also for ICS it requires at least one r 2 recharge cycles for things 2 settle down

Suggest you to root your phone and install a custom rom like wanam/slim etc. These will remove all unnecessary bloat wares giving u better battery and performance. (Do remember to read all the necessary info before u root).

Have you tried BadAss Battery Monitor?
imho: too many running services in background.. try to kill/freeze unnecessary apps(use link2sd), but most important thing is it seems that current ics is not optimally written/optimized, most kernel can help minimize this effect (but minimal e.g. speedmod)... if you can bare with this condition you ics is for you.. but if you are expecting an optimal performance of your sgs2, you should consider reverting back to gb ..
If you wish to remain on Stock Rom, please root your phone. CF-Root kernel here

Find out, with process drains your battery.
Use BetterBatteryStats und look for kernel wakelocks after display is 1 or 2 hours off.
I had the same problem a while back and battery would go down to 20% in about 5 hours. Did a factory reset because when I upgraded, I didn't wipe cache. I read somewhere that old gb code could cause issues.
After the reset, phone works great. I get to 50% battery in about 13 hours. If you can, give it a shot. Of course, back up paps with Ti, otherwise reinstalling them is a *****. :banghead:

I'm quite satisfied, after first cycles now with stock Italian LPF and Phenomenal 5.4 Medium Kernel I have very satisfing results (I forgotten the phone on this night, in 5 hours it drained at least 1-2% of battery).
In normal operativity I'm on 13-16 hours with 1650mhA battrey.
Thanks will do that and post results for further help.
Battery life has now improved to about 15hrs since taking the battery out for recalibration and putting it through a few charge cycles. But this still feels to low.

oooor you can downgrade to Gingerbread and get a custom rom/theme for that awesome ICS feel and at the same time get awesome battery life

OK! I've read your situation. This is the only thing that I can recommend. Try installing a Gingerbread rom and see if the issue persists. If it does then some of your application could be the culprit behind the battery draining issue. But again, thats just a guess...And if it is one of your applications that is causing the drain then you should install bettebatterystats from this thread:
http://forum.xda-developers.com/showthread.php?t=1179809
Then charge your battery to 100% and try a new calibration method, maybe you haven't heard of it. But if you charge till 100% then take out the battery for exactly 3 minutes and put it back in and power up your phone and use your phone normally as you do and then at 20% or lower go and check betterbatterystats and see what is causing the most of the battery drain.
Have a great day and good luck with the battery drain, hope this helps!!

i did read about the new method today, but havent had the chance to try it yet.
im not sure if it's a certain application that causes it, but in the battery stats it points out "Android OS", i've seen many galaxy nexus users complain about the same problem, even with stock kernel/roms, and galaxy S2 users that moved from gingerbread to ICS. it's logical that ICS will take more battery because of the control over multiple cpus and all this kind of stuff but im not sure how much it is about that "Android OS".
anyway ill try to have this battery calibration new method once my battery will drain out, and im probably not going to go down to gingerbread again because i already know its not gonna persist because i remmember how my phone behaved on GB and that those 2 systems work completely different and i want to solve the drain per ICS and not solve the issue by downgrading back down to gingerbread.
thank you for your time and help anyway
