Somehow, it seems over time battery life on ICS has consistently diminished. May try some things but this is stock rom, and really not a lot of apps widgets. Is everyone having this?
Example, Sunday I unplug it at noon, and by 7 its at 4%, made a few calls, say 3 under 5 min. Used navigation some, texted some, and a bit of fantasy football app. But that seems below reasonable expectations.
Widgets: 1 weather, Tim Hutt ICS calendar, SiMi Clock, battery & Weather(lockscreen), Widget Locker, Google Music. Launcher: Apex pro.
Did a bit of surfing and didn't see much around stock ICS (could have missed it)

I have the same problem too. The battery life is so horrible :crying:
I need to charge 2 - 3 times per day. I am thinking of downgrading to ginger bread if this continues.

I'm on the US AT&T stock ICS. Have not tried any roms.
If you upgraded via kies or OTA...the chance of a corrupted flash is high.
I'm not saying that it is, but we have had several reports of failed OTA or kies upgrades to ICS...
The only good fix is a re-install of the build...
I would go to samfirmware.com, and push the rom to the device again, and then test the battery life.
this would not be the first bad rom image we have seen from the upgrade.....g
And remember, it takes 3-5 days of normal usage after a fresh install, for the dalvik cache to build, and for the device to "settle" before any accuracy can be measured...g

If this is the case, should I try something like a factory reset then reinstall? I initially updated via Keis.
What is typical battery life on ICS? I recall I got the note right before going to SXSW and it would run from 8am to 11pm with solid use and maybe a 10-20% top off somewhere in the day. This has given me serious cell phone "range anxiety", even bought a external battery to address it.

Best screen on times I've seen are ranging from 3-4 hours, and overall battery times are going 18-24 hours...
Now mileage varies greatly between users, and i'm running ICS as well, and since 6 a.m. today, I've used 14% battery in 7 hours...
I've made 2 phone calls, sent 3 texts, and messed around with settings for about 30 minutes...
It does sound like you may have gotten a dirty flash image...but it's so hard to tell, unless you get random freezes, boot loops etc.
But the stock ICS battery life was horrible for me........g

It boots and actually runs fine. Occasionally cell standby chews the battery out of nowhere, andriod os and phone idle too.
I pulled it off the charger today at 9am and as of 2:00 I was at 68%. Checked email, messed on flipboard while making coffee, updated a few apps. Checked traffic. Mostly just sat on my desk.

I really think you should either re-flash the stock build using samfirmware.com, or flash up a custom rom you can adjust to get this battery issue under control...g

Understood ...
Fortunately, the note is painless to use on custom roms ...
With the ATT version, you simply push a custom recovery to the device via Odin, then download and flash the rom.
No root needed. And if you don't like it, you restore the stock nandroid backup and presto...no more rom.
Root is very nice though, as it allows sooo much more control ....g
Extra Batteries, their cheap and totally worth it just make sure you get a wall charger too
I've pretty much given up on eking out more battery life since it seems universally bad.
A bit more than 4 hours screen-on time seems to be the limit without setting the screen to ultra dim.
Standby seems entire dependent on my signal strength and whether I have LTE enabled or not. If it's strong, 24+ hours isn't unreasonable.

Well, yeah screen destroys the battery. After ICS it seems as though they cranked up the brightness and contrast. Or is that just me?

Hi, I just recently flashed the LPG ICS Rom to my phone 2 days ago. I did the wipe and flashed through mobile Odin. I restored some of my apps and data with Titanium (also uninstalled most of the samsung apps)
I already did a battery recalibration (pulling the battery at 100% etc.) but I am getting pretty bad numbers. Just 7 hours tops, I guess a lot more if I dont turn on the phone but I guess this is really wrong.
Am I missing something? Should I uninstall or disable something more? This exact configuration gave me minimun 12 to 14 hours on a stock not ICS ROM.
Also I should mention that I am using Juice Defender Ultimate with connection intervals of 5 minutes, pretty average settings.
Any suggestions, tips or guesses?
Thanks a lot!
PS. I dont have any strange apps, just the normal (facebook, twitter, whatsapp, Talk...), My display brightness is set to auto.
What really matters is screen on time and you are getting barely 2 hrs and that is indeed awful but in line with all the complaints I've been seeing in the forums.
The update I got was not LPQ but rather LPE (Trinidad & Tobago) which was released the same day as LPQ. I am getting 4.5 hrs screen on time (around 15 hours with my usage habits). This is barely acceptable as I usually got 5 hours 15 min of screen on time with my stock 2.3.4.
Hopefully Samsung will fix this soon, it was supposed to be the other way (battery life improvement).
Soo...
So I guess I'll just have to wait the next rom releases, as it seems that they are improving the rom every new release? Does that make sense? the roms are being released almost one day apart from each other, arent they the same?
In case that for example a new rom comes out tomorrow and the fellows here say that it really improves battery life. What should I do? wipe and install just as this one? or would I be fine without wiping?
Thanks a lot!

Their is no normal battery usage and you have not given battery any time at all to recalibrate .
Just read the battery posts and use Better Battery Stats .
If their is a problem a full wipe is always best .

Ok, so after a couple of days using it.
The battery now lasts almost 9 to 10 hours with normal use. but I deactivated Juice defender.
Now I have disabled all of google location stuff, and some of google services autosync (like google photos and reader). And will turn on juice defender to see how it goes.
Ill update my findings.
Thanks.

Snce I have updated my GS2 to ICS my battery drains insanely fast. I don't even do anything with it. I go to the battery consumption table and it seems like the screen is overusing the battery. The rest are fairly normal percentage.
Like I mentioned in the beginning I only have this problem when i'm using ICS. Right now I have the stock ROM that I downloaded from SamMobile. When I'm using custom ROMs it gets worse. What could this be?
And yes I did try to search for similar problems, because it seems like a lot of people have problem with the battery but no one had the exact same problem as me.
I can just add that since I last charged my phone my screen has been on the lowest brightness and the phone had just been lying on my desk. I haven't even touched it. still 7% has been drained and the screen seems to do the job.
Does anybody know how to fix this?
Same to me....Plzzz guys...Help US.
Battery drain is the hotest topic on ICS these days. I believe the high RAM consumption of ICS is causing battery drain. Almost every ICS rom is having this issue. You are not alone. Relax and wait, you will see improvements.
-
In the mean while, you can install "betterbatterystats" to find out what is draining your battery. Good luck.

So when you clicked on display, it showed that screen on time is 1 hour, and your battery is currently at 77%? That isn't terrible, actually. That means you're on track for a little over 4 hours of screen on time before your battery will reach 0%. Average screen on time for full battery discharge is usually around 4-5 hours.
If you are using the phone, and the screen is on, the battery WILL drain.

No believe me this is not good battery time at all. I have screen on lowest brightness and barely use it. Even when it's just lying there with screen off it drains a lot. I mean I have had this phone since last summer so I have had it or a while and he battery was pretty good before. But since I updated to ICS the battery drains a lot faster than before.

You just said the screen said it was on for an hour, and the battery was at 77% in your post above. So was that not accurate?
If it is draining more since you upgraded to ICS, and you want it to get better, then you have three choices:
1 - Install BetterBatteryStats and other monitoring apps to figure out what is keeping wakelocks and other processes running on your phone that is draining battery...
2 - Do a factory reset/full wipe and see if it was an errant app you installed that could be draining the battery, then slowly start adding your apps back one by one... or
3 - Flash back to a Gingerbread firmware.

Yeah I guess you're right, but at the same time the battery is very very bad compared to before so I'm confused. Maybe I was just enjoying a really good battery time back on Gingerbread?
1. First of all that BetterBatteryStats is too complicated for me. I tried to use it before I didn't get it. What am I supposed to do when I find something that is draining my battery. Should I freeze it? Uninstall it?
2. I have tried this a lot of times, no change.
3. If I use Gingerbread for some reason the APN settings with at&t doesn't work properly. I lose connection very often. So I'll rather have worse battery time for now. Is there a solution to the internet connection?
Thanks man I appreciate you taking your time!

What modem/baseband are you using with Gingerbread, that could make a difference with mobile data dropping.
Also, what APN settings for AT&T are you using? There are a few different APNs. The two major ones are "wap.cingular", and "phone". The one you should actually use will depend on what kind of data plan you are signed up on.

Do you have the APNs for "phone?" It would be awesome to have that. Then I could just go back to GB until they fix it.
BTW I checked my battery stats again, 24% left. It says screen 56% and Time on: 1h 54min... So it's is pretty bad, right? . It dropped really fast.

APN for "phone" doesn't work unless you have a specific data plan - namely any 4G plan. So if I recall from some of your past posts, (I remember you now) you're on the non-smartphone data plan, right? Then the "phone" APN won't work for you if you are.

So you're running a clean flash? No downloaded apps installed yet? Yeah, that's terrible. Sorry to hear. I would go back to Gingerbread.
Reading stories like yours makes me glad I'm still ON Gingerbread.
The problem is that I'm not really using the screen that much. today I have just listened to music, not even used the screen that much. Just text a little bit an nothing else.
But still it shows up as if I have used the screen more then the other apps running in the background. Remember my screen is on LOWEST brightness level and I barely use it.

Stock XXKI3, (2.3.5) I have several mods though.
If all else failed, try shutting down your phone, take the battery out and clean the battery contact points. Dirty contact points might be the culprit.

Just throwing this out there, I have played around with a few of the ICS roms, using safestrap installs, to retain the back to GB option. I have found that I get about 50% less battery life on the ICS roms. On an average day I use my phone moderately, past two day, back on GB, at around this time of day I am at about 60% battery. While on ICS leaks, I was at about 30% with similar use throughout the day. Anyone else have such a stark difference with ICS?
You have to give it at least a day to settle in. I get better on ics.

I have stayed on the Roms for several days(a week on first round of trying them out) and still much worse battery life. You are on the GSM Razr? I am on CDMA, you know of any difference with radios that would cause the difference? Generally have LTE off both GB and ICS.

My battery is slightly less on ICS, but not dramatically different. I can confirm it's not my usage or imagination either. Battery stats show "Android OS" is using 5-10% more than it did with GB.

if you go into your battery usage youll see that your screen is using 50% or more of the battery. there are battery issues and moto knows about them, im hoping they will fix this, ive read articles that they are gonna fix this bug before releasing the ics to the public.
my battery is the exact same way on ics, i hate it, but since i got a maxx now i could care less. i accidentally deleted my screen shot of the battery usage. and if you look at the ontime of your screen youll see that it is a 5th of the ontime of phone, (at least for me it was)

I was a bit hesitant to agree about there being a battery issue, until i was satisfied that id had enough time with the ROM.
But the truth is in the pudding so to say... I am able to make it through the day but i am getting at best 2/3 the amount i was on gingerbread.
9.5 hours of battery, 80% of which was taken up by screen time of 4hrs.
Yesterday i was convinced battery was fine, today i know there's something's amiss

I have found the exact opposite. My office gets horrible cell reception and my phone was constantly trying to connect on gingerbread. It would always show the kernel as using the majority of the battery. Since ICS my phone rarely drops connection and my kernel now barely consumes any battery. I'm making it until five everyday with 50% battery left while with gingerbread my phone was always dead by five.

I was in the soak test, 1st I got the standard email getting everyone's opinions of the soak. Then yesterday I got a 2nd email from the MFN for a 2nd survey. This 2nd survey was all about the battery life. So, yeah, Moto knows that there are some issues with decreased battery life. I've noticed a decrease in battery life. Even so, I'm still happy with ICS. Most of the issues I've noticed have more to do with apps than ICS itself. Some apps, when I want to go back a screen, it instead takes me all the way out. Even the XDA app does this. Anyone else notice this issue?
I'm not 100% sure what the cause of the battery issue is.
In my case, on GB I would could typically go from about 6AM to 4PM before I would need to charge it again on a normal Droid RAZR. On ICS, at first I could only go for only about 2-3 hours before experiencing a 50% drop in power - meaning only about 5 hours before needing to hit the charger. For this reason, and other issues, I opted to perform a Factory Reset. It solved the problems I experienced, including my battery issue. On ICS, I can now go from 6AM to 6PM with a battery meter reading of 50%. Translation - for the first time with this phone and normal use (for me) I can go all day without having to worry about a charger. So, this is a huge improvement. But it did require a Factory Reset for me to get this level of performance.
I would like to be able to say the same but.... I did a factory reset before and after loading ics.

Just curious, when you installed, how did you go about installing/reinstalling your apps? When I did the reset, I just let Google Play do it automagically for me. It got me about 90% there. There were a few things I needed to add and configure. Also, I stopped using another launcher and just went with ICS. I don't know if those are differences that might make a different or not.
I actually did not let google restore anything. I wanted a fresh base to work off of. Installed from market one at a time.

Actually the first china leak (120) gave my battery a lot more usage time,significantly.
But when i switched to MIUI rom my battery life significantly dropped down,every minute of usage=1% of battery .
Try to use the stock rom for a couple of days,at least the stock leaked china rom has very good battery life for GSM devices .
I've had ICS for a week now. At first my battery didn't lady add long. But after a few days and a FDR it its lasting longer than it did on gb.

My battery is slightly less on ICS, but not dramatically different. I can confirm it's not my usage or imagination either. Battery stats show "Android OS" is using 5-10% more than it did with GB.

Values 5-10% for "Android OS" are the values of my dreams as I am used to +/-25% on the GB...
Lately my battery usage in battery monitor widget has been going over 1000ma multiple times a day. In fact this has been the case both at the beginning of my Rezound's life on the first firmware, and again now.
At one time in between I used to never see it go over at most 700ma, and experienced reasonable battery life too. Usually I saw about 70ma to 300ma usage. This was with several different roms on the same firmware. I think it was the first or second ICS firmware but I don't remember for sure.
I'm starting to think the firmware a few versions ago was better on battery life. What do you guys think?
I was running GB with the old firmware up until just last week. I was averaging about 20 hours on a full charge with 1-2 hours of screen on time. The rom ran great and the only issue I really had was my 4G would cut out completely whenever I tried to play Youtube videos....
Last week I updated to the latest official ICS global rom with the new radios and firmware, and my battery life has gone in the toilet. I'm averaging about 15 hours on a full charge with the same 1-2 hours of screen on time. My phone gets MUCH hotter when just doing simple things like browsing the web, often getting above 100* F. On GB firmware I was usually in the mid 90's unless I was gaming. This is with the stock kernel. For the past couple days I've been trying FunkyKernel with some under clocking and undervolting which has helped the heat but not so much the battery life.
I'm kinda pissed and strongly considering finally going S-OFF just so I can roll back to the old firmware.
I actually think I had the best battery life on the first ics firmware, but like I said it might have been the second one. I don't remember how many there have been, but I have done all of them.
This latest one just seems to suck down power.
Anybody else have some input?
I just recently updated to the official global firmware and am running Rezone Redux with Funky 3.7. I'm not doing any undervolting and the only change I made to the frequencies was setting the min to 96 and the max to the stock 1512. With my extended battery, I'm averaging around 4.5 hours of screen on time, which is actually about 30 minutes more than I've ever gotten out of this battery. Then again, I keep my data, WiFi, and GPS off at all times unless they're needed, screen brightness at 13%, I'm using an app called Greenify to hibernate certain apps (not freeze, there's a difference), and I'm using the Wheatley governor. I'm very happy with this setup.

So maybe it isn't affecting your as much because you keep your radios turned off. I also use greenify and it has definitely helped.
I might go a day with my mobile data enabled all day and see what happens. I got into the habit it of toggling my data off about a year ago. The only reasons for me to keep it on would be weather updates and Facebook notifications, neither of which is really important enough to me to have them refresh automatically. I don't use push email or anything like that, either. I suppose it would make a difference for someone who needed instant email notifications and such.
Sent from my ADR6425LVW using xda app-developers app
I also keep data off most of the time unless the phone is plugged in, but still, battery just hasn't been the same since the latest firmware update...
I want to update you guys on my battery issue I thought was related to the new firmware. Every rom I had used since the newest firmware release was horrible on battery life. Using battery monitor widget to monitor power usage, I was often seeing over 1000ma usage many times per day.
I recently installed neo's infection 2.9.1 which uses a stock kernel based off Flahalf's work. My extreme battery drain is gone! The highest usage I have seen in 2 days is around 500ma, and normally it is 100ma or less! Not only that but this Rom is smokin fast. It feels like a new phone!
And it fixed wireless tethering! I'm so happy and thankful for the awesome work or devs have been doing. Thanks guys!
Unfortunately for peeps like me who enjoy gaming on their phone, the JB roms aren't all that great. Graphics performance is generally poor....
Maybe you should give it another try. I just played some shadow gun and the performance was fine.

Then you must not have looked very hard, it is here on XDA in the Rezound Original Development forum, along with other amazing ROMs like Tron, Beanstock, Liquid Smooth, PAC-Man, etc.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this
5) Read about jb settings/issues.
Sent from the little guy
Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.
You searched Ebay for "Samsung genuine 2000 mAh battery" or similar?

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.
