Galaxy s2 didn't have great battery life when I first got it. I didn't do exact calculation, but it was terrible with minimum usage.
After updating to the latest firmware, I was hoping for improved battery life as stated. I was getting the same battery life as before. Nothing has change, except my storage space got a lot worst. The system data files was taking 900MB internally!
So i did a factory reset to clear out the junk in the system data folder. It's back down to 67MB. Restore all settings and apps back onto the phone and now getting much improved battery life.
So for those of you that updated and see no changes in battery life, try backing up all your data/sms and restoring to factory again.
Where did you get the update? I have recieved nothing ota. Still running stock 2.3.5. What other changes did you notice?
I think some people just get a bad battery. This phone has the best battery life out of the 20 or so Androids I have owned. But I have always conditioned it well. For example when I first got it I plugged it in and didn't unplug it till it was fully charged. Then used it till out was almost dead and repeated that for the first week. Seems to make the battery golf a better charge for its life time by song that in the beginning.

the t-mobile support forum for the GSII has instructions for updating manually. I'd post the link but i'm still too new apparently
When i did the update, the Kies software would detect my phone and do the update when i had USB Debugging unchecked.
My battery life has significantly gone down since the 2.3.6 update. I could easily get 2 days out of my phone and if I didn't use data, I could probably squeeze out 4 with minimal usage. Ever since the update, the Android OS has been my biggest Eater of Battery. It destroys it and I haven't really been able to correct it. Some days do better, and the others just drain it for no apparent reason. I'm not sure if it's the bloat ware causing it or what. I just wish the "Android OS" was more specific as to what's new about the update that requires it to murder my juice.
When I first got the phone (2.3.5), I did have a the Android OS problem eating my battery but I guess I fiddled with it enough to where it went away. I don't have a reason why.
I do use ZDBox and Android Assistant (both times) to help with program limits and stuff.
Would a system restore help out and does it wipe out all my applications?
The update made my phone better so to each his own.

I upgraded my stock rooted GB SGS2 to ICS with Kies on the 12th. Battery life has been awful compared to what I got on stock GB (15-18 hours with normal use) I'm now losing about 10% an hour just sitting idle. If I use my phone at all it won't last 8 hours before the battery is at about 10%.
I did a factory reset and re rooted two days ago and I made it about about the same amount of time before the battery was almost dead again. Last night, I did a factory reset and flashed T989UVLE1_T989TMBLE1_T989UVLE1_HOME.tar with odin then rooted and still about 8 hours after I took it off the charger it's at 20% and I've barely even touched it today. I do not have any apps or widgets installed that I didn't before on GB. I didn't restore the apps with Titanium Backup, I manually downloaded each one from the Play Store. I've wiped the cache and fixed permissions in an attempt to get S-Voice to stop crashing.
Another problem I have is issues with bluetooth routing calls through my cars bluetooth. When it is paired my notifications skip and sputter when they go off.
To the best of my knowledge when I Odin'd back to stock ICS that wiped everything out but since I had an issue with my old Vibrant having remnants left over when flashing ROMs I'm wondering if this could be a similar issue. I usually flash with CWM and not Odin Is there something I should be doing to completely wipe everything out and go to stock ICS? Most all comments I've seen say battery life is even better than GB. Mine has gone the opposite way. Help?
Download TDJ's superwipe (theres a thread for it in the dev section) and run it, THEN Odin the stock tar file.
Thank you!
I notice it says after doing to the super wipe to stay in recovery and flash the ROM. Should I find a flashable zip of ICS or is it ok to use Odin after?
I flashed the zip and went ahead and went into download mode and odin'd stock ICS. Google is actually restoring my apps this time...it didn't the first three times so, so far so good. Thanks for the help.
10 hours with very little use and battery us at 25%

D2H, Question for you... You're rooted, have you tried calibrating your battery yet? The only reason I ask is because I was stock unrooted when I upgraded to ICS and my battery life too sucks BIG TIME. Maybe 5hrs, 6 definately tops. I even tried factory reset (which is questionable), removed the battery, let it drain completely and then pulled the battery again and full charged. Still on pace for 15%+ /hr. with light usage.
When I rooted my Sensation I used a battery calibration app and that improved my battery life by leaps and bounds.
I was thinking of rooting my SGS2 just for this.
No, I've not tried that. I used to do it with my Vibrant and never really saw a big difference. I also saw a post here somewhere on here stating that calibrating the battery was a myth.
I may as well try it though. Otherwise I'm going back to GB as this battery life is unacceptable.

D2H, so whats the status?
Myself I finally bit the bullet and rooted (OMG SO SIMPLE compared to HTC). After rooting I downloaded "BatteryCalibration" from google play (Same app used on my Sensation). After a full charge yesterday, I calibrated...to TRY to drain my battery down completely for the next charge I turned on BT and GPS. This all happened around 8pm last night... Well its 5:08pm next day now and my battery (with BT and GPS still on) is only at 68% now and that's after some surfing, video watching, games.
I have to say give this a try before going back to GB.
Come to find out there was a beta release of HD Widgets that downloaded when all of my apps restored. That was the culprit. I'm back to 16 hours of battery life.
Cool! It's going on 10:30 pm here and my bt and gps are still on and I'm at 29%... This includes more Internet browsing, games, phone calls and Txt msgs. No charging since yesterday. I won't be surprised if it's still on tomorrow morning.
Hi all,
My battery life on the One X has been great before the 2.17 update. Better than the average being reported on this forum.
After 2.17 it plummeted to 14 hours or so with barely 2 hours of screen time.
Nothing was changed after the update on my end. Same apps, etc. All on stock.
What are my options? Will a hard reset solve it?
Thanks.
Update
The factory reset did the trick. Battery is back functioning properly and I did get extra juice out of the 2.17 update.
If you do find a weird drop in battery life and the ONLY change is that you updated the firmware, a hard reset may solve it like it did for me.

You should go thru a couple of charging cycles before complaining about battery time.. everytime you flash a new rom or update the phone the battery has to calibrate ( as far as i know ), and that takes about 2 - 4 recharge cycles..
in case you already done that, then check you sync settings, brightness if its too high, or low.. Maybe you are used to be on wifi instead of 3g ?
It has gone through over 10 full charge cycles.
Sync is off. Brightness minimum.
Wifi and 3G usage patterns are similar.
Just noticed that Phone Idle is consuming a lot more.
Maybe it's the new radio which is affecting your signal, try flashing an older radio. My battery life is better on the new firmware.

i first of all found the battery life had dropped, i ended up resetting the phone and it got much better, i think some old app was getting lodged in the memory and preventing deep sleep.
i ran it for about 2 weeks before i decided to wipe.
@nikzDHD
I suspect it could be that. My provider does not provide that strong a connectivity. But that is something I can't change for the next year or so.
@audiobookman
I decided to wipe it today. Also waited about 2-3 weeks before deciding enough is enough.
--
I did a HTC Battery test and found that my battery was in good condition and performed way better than their baseline. So, I went on to wipe the phone clean and started from scratch.
It was not a painful process actually. Most of my stuff are on the cloud (Google/Dropbox/Skydrive) and the only things I had to back up was the list of apps I had and some settings from apps like Tasker and Minimalist Text. I got everything back up and running within an hour + (reinstalling 60+ apps and getting them setup the way they were takes time).
So far, battery seems a lot better and back to the former period but, it is too early to tell. I'll give it a week of use and a fair amount of full charge cycles before commenting.
Will update this thread then.
If anyone has other ideas please sound out. Thanks a lot!

Hi everyone,
My One X used to have brilliant battery life. I didn't turn on the screen that often throughout the day, but I was able to regularly check the news, send and receive texts, make a few calls and - crucially - keep my Wifi on for the entire day. With this setup, I was regularly getting 4 or 5 days of usage without having to charge my phone. However, as soon as JellyBean came along as an official update, I grabbed it... since then, I'm lucky if I get a day and a half out of it before I need to plug it into the wall.
I'm not running any custom ROMs: just whatever I get through official O2 OTA updates. Battery usage says that 36% of my drain is due to Android OS, with another 20% due to Maps. The rest are tiny, only 2 to 5%. Now I understand that a new version of Android might make some new demands on the hardware, but from what I heard, the update was supposed to improve battery life if anything. Even with the new Power Saver feature on, the difference is minimal, with only a few hours standby time gained overall.
Can anyone suggest anything to remedy this, or is this fairly normal? It's not world-ending and perhaps I was just really lucky to get 5 days of use in the first place, but thought I'd ask the experts before I grin and bear it. Thanks in advance for any help or advice.
19 hours and 40 minutes into this usage cycle, I've got 57% remaining. So it's shaping up to be about 40 hours of usage, down from 120 at its peak. Right now, it's also saying that Android OS has used 99% of my battery... and nothing else is on the list.
Does no-one have any idea what's going on?
Did you make an hard reset when you updated your phone?
This is why when you upgrade your phone to a newer Android version it is better if you perform a hard reset

Thanks for this. Your suggestion got me checking for other people having issues with Google Now and battery life. I disabled it as you suggested and I'm definitely seeing an improvement. It's still not as good as it was, but I think I might be able to squeeze more than two days out of it now.
Do you have stock rom? Because I've just upgraded to JB yesterday and flashed a custom rom, and since then my battery is like 3 times more powerful.
You should definitely switch to a custom rom... Ever since I upgraded to JB I've seen a massive improvement in my battery life.. From barely making it through the day to almost 2days of my typical of usage.
Google Now does seem to kill battery as it polls the Google maps app a lot.. So I usually open task manager to make sure it isn't running in the morning background.

Bone stock, not rooted or rommed.
My battery life used to be phenomenal. I would check at the end of basically every day and averaged 4-8 hours of actual Screen On time. The Screen would account for 40-55% of the usage, followed by all of the*apps*that I had used that day. Android System and Android OS would be pretty far down on the list.*
Now that I have 4.1.2, I'm lucky to hit 3 hours of Screen On time. And now Screen, Android System, and Android OS are accounting for 20% EACH.
I haven't changed any settings or the way that I used the phone. The only thing that has changed is the update.*Is anybody else experiencing this?
I've gotten bettery battery life since 4.1.2, significantly better. Try to perform a factory reset or it could be a faulty device.

Yep and I have more or less tried everything including tweaks galore, every suggestion I coukd find, and freezing several dozen apps.
Nothing can be done about this and my guess is Samsung have made an absolute mess of the update. My HTC loses maybe 1% overnight on a bad day, this loses way over 10%.
I'll prob end up switching back to 4.1.1 but unfortunately it doesnt have the tap to reflow feature in the browser (which I use a lot)... I wonder if I can remove it via titanium and restore the newer version which would have reflow on 4.1.1 ??
I have the same problem. As soon as I took my phone off the charger this morning it dropped to 99%. On 4.1.1 it used to last for a good 20 minutes before dropping to 99%. Also last night after about 6 hours of screen time Android System was at the top of my list. And that is with 20 or so system apps frozen or deleted from running.
What's the easiest way to go back to 4.1.1?

Well I dunno.. I have tried everything and there is definitely a battery drain issue. If it is caused by ebay/whatsapp + facebook, then I'm curious as to why they don't show up in battery usage or betterbatterystats... and I'm also curious why the exact same setup on my HTC EVO 3D does cause these horrendous idle battery drains.

Yeah already done all that and there doesnt actually seem to be anything using over like 5%.. I have elimated the higher one yet it still drains ovwr 10% at nite. Or in general idleness.
What I became accustomed to with my previous phones was 0% or 1% drain over many hours if the screen was off. Not 2% or more an hour.

That's specifically my DBT rom (stock everything as well) and I've had battery issues and to be honest, it's still better than most other phones, but I'm getting about 40% less life out of my device now.
I have flashed again, I've reset, and deleted everything and still no luck. It's something with the ROM. I hope the next update will fix it. If it doesn't, I'll revert back to 4.1.1 because I would go to bed with 50% battery life, now I have to charge in the middle of the day if I want to get through a long work day with lots of use.

On kitkat I was seeing 5-6.5 hours of screen time. Now on lollipop I get about 4-4.5 Hours. I have done a clean factory install and wiped the cache. Android system is always at the top for me as well and it wasn't with kitkat. I actually have less apps and data on my phone now than I did on kitKat because I wiped everything. Ive been using lollipop for about a week now. This is obviously an issue within lollipop itself. I have mirrored the same settings that i had in kitkat, disabled as many useless apps and files that i can, and I'm using it exactly as I was on kitkat. Can someone just root this phone already?! PLEASE? (I won't hold my breath lol)

I noticed that just by changing that setting I get two days easy on one charge, please note that when I say two days I'm not on my phone all the time, typically I pull my phone out at work for demo purposes, I'm browsing the Internet on down time, I'm streaming music on my drive home or I'm texting or playing a simple game. Anyways, not sure why the enhanced services drains battery so badly but after I turned it off on kk and updated it was back on and I had horrible battery life, was gonna factory reset but then checked this and it was on again so now I'm back up to two days on a charge.
My first day running Lollipop I got around 5.5 hrs SOT and phone was on for more than 13 hrs and still had about 12% so I'm getting around the same battery life on heavy usage that I had on Kit Kat. I'm having no issues with Lollipop as of now. Before I downloaded Lollipop I moved all my important files to my SD card and then I updated. Right after the update, I went into recovery, cleared the cache and factory reset within recovery. I've had a very smooth experience ever since.

I have found a fix that has worked for me without resetting. I cleared my cache partition and now I'm back to almost as good as it was. Not quite 100%, but it's a drastic improvement. I'd suggest trying this before doing a factory reset. It worked for me.
And FYI, I tried waiting for as long as I could stand it and it didn't get even a little better.

No question about the Enhanced 4G LTE setting. I was already getting at least as good and probably marginally better battery life after 5.01. Turning off enhanced 4G services has given even much better battery life. Just as others have seen, Android system has dropped in usage. In fact it is amazing how long this phone can now go between charges.
After a week of 5.0.1 (see nothing difference of the interface cause ATT made it). I have to switch back to 4.4 for some of the features missing/not support and i got back my best battery life. It's ok in 5.0.1 but 4.4 battery is best.
In 5.0.1 i got around 3h screen time and it's drain faster.
