From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

same here i upgraded to ICS xxlpq and have been using it for 3 days, im struggling to get a day out of it ... its exactly the same setup as when i ran XEU (KI4) 2.3.4 unbranded UK. I noticed ram usage has increased as well as the amount of system processes. both times I rooted and removed bloatware. when my contract runs out in 6 months I will be looking at either a pure asop phone or an iphone 5, The galaxy s2 has a great screen but the batterylife if weak no matter what custom rom and custom kernal is running. Also I can get a wifi signal in my bedroom with my laptop and my old iphone 3gs but nothing with the s2.
Also please can anyone advise what the best pure and minimilistic asop rom will be for the galaxy s2 ive read cm9 mite be soon but is there anything thats great for battery life ? ...... thanks for you time in advance :=)

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.
Cheers

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers
I flashed CM9 on my GSII on Friday and ever since it's had 5-6 hours on usage. I've tried doing the battery calibration stuff, seemed to be better Monday and today it had 50% after a few hours of gaming so that seemed normal but then i reset it and it dropped down to 10%. I tried calibrating again and still 5 hours.
I've been using that Battery Calibration app and it game me 40% charge at ~3500mV. I'm not sure whether that is the battery volume but seeing as 100% was 4200mV something seems wrong.
Anyone have any ideas?

It isn't ICS, i flashed it on a friends GSII at the same time and his last 1-2 days like usual.
i´m test ics roms, and have much differences between them.-
maybe the kernel makes the difference.-
But is a fact that GB has better battery management, that ICS

I have an LG GT540 as well with ICS on it and that would get 8 hours regular usage with it. My GS2 get's less then that without me using it.
Ok you compare with other device, i Spoken to Galaxy s2, Ics have bad battery management, in sleep mode.-
But I´m still test the slim rom with neal kernel and have 53% battery after 30hs. with a general purpose.-
try it this rom an kernel,.-
As was already pointed out, bad battery life is almost always a rogue app keeping the phone awake, install Better Battery Stats and CPU Spy to monitor wake locks and deep sleep, if you find a problem with an app keeping your phone awake, uninstall it and your problem will likely go away. Personally, I've been running CM9 and other variants of ICS for months and I get less than 1% per hour of drain while the screen is off and the phone is asleep, this is better than Gingerbread was.

Right, but background sync can still hit the battery, even with screen off. I was just curious.
Ive had days with horrible drain but it was almost always an app doing something dumb and keeping the phone awake, bad cell reception or a noisy wifi router. The trick being to identify wake locks that seem suspicious and track them down.

I use the stock rom and after the Update on ICS i noticed my phone is getting really hot even when im not using it. I tried using advanced task killer to close app running in the background and i also close every app i use in ics multitasking... its draining battery very fast! 40 % in 30 minutes. Its not warm the whole time just sometimes it gets warm and drains battery... dont know what to do :/

Taskkiller itself is not running in background. i use it sometimes to look which app are running in background and to kill the ones i dont need. The problem is the battery status is looking normal. Display 33% phone 19% and some other apps do also drain battery.... but the problem is its only getting warm when i dont use it. sometimes when its laying on my desk i pick it up and notice this. when i look at my battery then its sometimes 20% less then 10 minutes before when i checked facebook for example. for me this must be something with the firmware or not? or some hardware defect?
maybe take it to a mobile service
Did you make wipe after ICS update? Maybe its a bad configuration after the update.
Also, you can try CPU Spy in Google Play and tell us if phone is on state "deep sleep" (when you lock the phone, it should enter this state where battery drain is minimal).
Make screenshot of Battery Usage screen and post it here.
Then install BetterBatteryStats, use it for few days, then make screenshots(Partial Wakelocks, Alarms and Processes) and post these here.
I have the same problem, but I know it comes from the Exchange service. Sometime it becomes crazy and drain the battery + heat the phone.
For now, I just have disabled my Exchange account... Not really a good solution.
I have found others thread talking about this problem on other phones (all with ICS), but found no answer.
I did not made any wipe, nor before, nor after the update (from stock GB to stock ICS).
It's not very helping, I fear...
just a few senteces about my day:
The battery was loading untill 7:15 today then i went to school; my phone in silence mode and i used it for 4-5 whatsapp messeges and maybe 3 facebook checks and 1 or 2 instagram checks.
it got hot a few times again and its on 34% now. really bad i would say. on gingerbread i had like 60-80% after a half day in school with much more use.
Now i looked what drained Battery. in ics i cant take screenshot so i just write it down:
40% Facebook Calendar Sync
19% Display
10% Phone
8% STandby
6% WLAN
5% Android Core Apps
4% Facebook
4% Android OS
2% Android System
This is the first time i look at the battery drain seeing that Calendar Sync is taking so much Battery. I still believe it could be something else because before it was nearly the same without calendar sync and display on first place.
So for now i think im going for a wipe, hoping it will be better then.
i will share my experience with you asap. :good:
woah, 40% on that FB crap?
also, the system standby usage seems a bit large also.
try to wipe it, maybe flash some other ROM and see if it helped you.
a healthy battery usage would have display at 70% or so, phonecalls 15%, then all the rest.
depends on your usage tho.
but something is definetly wrong with your phone.
you said that the problem occured after you updated it,
so i think the hardware is out of the question (if the phone worked normal before the update), i'd definetly flash something there, the stock rom is useless anyways..
there are very good roms even if you have locked BL, check kamarush and the new CyanogenTimescape rom also.
keep us updated about ur problem
Cheers!

you must root first, then copy the rom to SD, reboot in CWM, and install from there. it's pretty straightforward from there on just make sure you select "locked bootloader" when prompted.
After the update from gb to ics I didn't notice a much higher battery drain. I use it like on gb and on my feelings battery lifetime stays equal to gb. I have got an unlocked bootloader but still on stock rom using rage kernel ics 3.2.

Soooo. I looke up what have drained my battery and it seems that the Xperia Facebook sync (The stock sync thats buildin in the normal firmware) have drained the battery. on GB everything worked fine. Now i deactivated the sync and the battery life is much better. It seems that my phone also stopped getting hot. But for me GB still had a better battery life. Today i woke up at 7 am (germany) and played Football Manager a few times between the lessons and in a free lesson so im at 16% battery now (should be ok because the football manager drains a lot of battery) and battery usage shows:
64% display
16% FMH 2012 (football manager)
7% Android System
5% Mobilfunk-Standby
4% Facebook
etc etc etc.
looks normal for me :good:
guys my battery life is fine now but i have freezes now... if i use my phone for whatsapp it sometimes just completely freezes. no chance to see a reaktion for any button any ideas wtf is going on there?
Battery drain that you've encountered is definitely not normal. I get about 3 days on ICS, and think that is what you should be getting as well. Crappy FB application is either bugged or broken, because you're not the first one that got their battery drained by FB calendar sync. My advice would be to remove FB calendar sync service, or disable it somehow, if you're not using it.

On the xmp with ics you have xperia facebook. its a facebook calendar, contacts etc sync by sony. This was the app draining my battery. i disabled it and now i have like 1 1/2 day battery with normal usage.
And for my problem with the freezes. i removed all bloatware i could but my phone is not rooted. i was thinking about rooting but i'm kinda new to the xmp roms and its hard to find ics ones that are working perfectly. before i had an lg p990 and i was using cm7.2. it was working like a charm.
i know how to root the xmp i saw some tutorials but im still not convinced

The ROM doesnt have an update because the devs have removed it because you just flash an update. As for the battery drain give it a few more days if the problem persists try another ROM. If it still persists after that try recalibrating the battery or resetting the fuel gauge chip.
Hope this helps

Hi,
NeatROM 3.5 is one of the best ROMs from battery backup perspective. And I can say that because I am using it since 3.5 came out and have never had any issues.
For a better battery life, follow the steps from the link,
http://forum.xda-developers.com/showpost.php?p=33045733&postcount=8776
Please note that the instructions are prepared to get the most out of your battery. Even if you follow the few ones that you are comfortable with, you will surely see some improvement.
Please press Thanks if this has helped you.

Its simple mate. Just download an app and hit a button.
Usually battery drain is due to one of two things.
-Phone not going into deep sleep
-Wakelocks.
Download an app like CPU spy. you can use it to see whether or not your phone is going into deep sleep like it should. Also, use better battery stats to look for wakelocks. Download the app from HERE , let it run for one battery cycle and then check for wakelocks. If you dont know what those are, spend some time reading that thread.
But if you want to hold off for a couple of days, you can do that. It does take some time for a phone battery to settle when a new rom/kernel has been installed, after which battery life tends to improve.

Thank you very much for your help mate. I've tried a couple of battery managers off play (juice defender and another one). Right now kind of regretting this download, everything seems to be going wrong;
1. battery is draining @ 15% in 20 mins ( I only bought the battery last week after having the phone unlocked).
2. there's a lot of lag
3. screens keep freezing and
4. keep losing reception and constantly having to restart phone.
I only downloaded this cause after unlocking my phone it failed to update. Is there any other that I can download that works well with SGS2?
There's no dearth of ROMs for the i9100 dude. Try a couple out and see if those help. If its stability you're after, maybe use an ICS Rom rather than JB.
15% in 20 mins isn't normal even for a first day..you sure it isn't a faulty battery right? Was it giving decent life before you switched to this ROM?
Try downloading a calibration app and see what the voltage is when it says its charged 100%. Should be around 4100-4200 mAh.
As for the lags and freezes, did you wipe data, cache etc before you installed this Rom?
Sent from my GT-I9100 using xda app-developers app
I had cleared the cache in settings before installing. Like I said, my first time doing this. Seemed straight forward at the time.
Since my phone is unlocked, will it return to ics4.0.3 which is what I had before?
Battery calibration app is showing 4161mv.
Will a factory reset help?
Thanks for all the help, site can be a bit confusing sometimes lol.

Cache from settings? No. I meant clearing cache from the CWM recovery menu. If you installed the ROM via CWM, that is.
If you did, I'd suggest reinstalling it again via cwm this time clearing data, cache and dalvik cache.
Ok..I just realised I totally assumed you'd installed it using CWM. Not sure if you did.
You can return to 4.0.3 if you want. Download stock firmware from sammobile.com and install it via Odin. I'm sure there's a guide on how to do that somewhere on this site.
Just noticed someone posted instructions on maximising battery. Did you use those? It could explain the freezes if they started after that. Some phones just can't handle undervolting etc.

Thanks and gave a great day!

Haha that's a lotta apps just to save battery. As long as it helps eh? 27% in 5 hours is pretty acceptable for moderately heavy use. Depends on your signal strength and whether you're using data or on WiFi etc.

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.

Do you bother reading the posts or just have a compulsion to post any old crap.
I see your advising people how to root,then you open up a new thread asking for help about rooting your phone.
And you are continuing to spam threads posting what other people have said already.

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
Regards

Wow, nice. Exactly what I'm looking for! I'm downloading the XEF update as I'm typing this. I'm going to try that and I will let you know the result.

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.

Wow
Im glad the XEF update helped
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.
