Hello,
i have a new galaxy sgs2 and the battery goes from 100 to0% in about 6 hours..
i have ics on it... is it normal?
tnx
If you're using it practically non-stop for 6 hours, yes.
not really... about 1 hour of 3g 2 hours of music and 30 min gaming.. the rest the screen is off...
if i dont use the pone at all it drops 100 to 90 in 30 min... and if i use it than in 20 minutes...

hi mate
yes you have bad battery
with wanamlite rom + speedmod kernel i still 54% of battery after 2 days of use
can you give us some screen shots of your battery performance?
what rom & kernel do you use?
Post your usage statistics
hey can you post an image of your battery usage? maybe i can help you if you do that, go to: Settings>Applications>Battery usage and press the home button and power button at the sime time, it will take a picture of your screen so you can attach it
You need to let the battery have two-three charge cycles after you flash anything to get an idea of the battery length

To be honest i was expecting a slightly longer battery life. Judging from what people write around here their battery life is considerably longer than mine.
I was looking at battery drain chart and was wondering if there is an app or another way i can check what contributes to my phone being 'Awake' as from what i see in the chart it's awake alot. Maybe a bit too much.

Upload a pic of your percentages, that'd help a lot with seeing what your problem is and therefore how to fix it.
Oh god, stop making new threads about the battery life. Your battery life is completely normal. Theres a thread JUST like this posted like 30 mins ago, I'll take my reply off it;

Becuase your phone was in use for a lot of that time.
Normally I get 7-10 hours battery life with my semi-heavy usage.
But yesterday I tested to see if I could get more, I only used the phone for four 5 minute phone calls, tonnes of texts, a little bit of web browsing and a little bit of youtube on 3G and wifi. No games or anything, and the battery still had 40% left after 20 1/2 hours.
But with my normal usage as i said, I get 7 - 10 hours.

long story short. Your battery life is COMPLETELY normal.
I have tried this trick and it works on my SG Ace:
1. Open your phone and charge it for 7-8 hours.
2. Shut off your phone, wait for at least 2 minutes and charge it again for 1 hour.
3. Turn on your phone and wait for at least 2 minutes and charge it for 1hour.
You will notice an improvement on the life and capacity of your battery.
Hope this will help.

Open....?? Startup or unscrew???
Also any proof would be great!
(Like how long did your bat last before and after??)
It is called Bump Charging.

Before i using The Ace Kernel Beta 3, but the carger of battery no work's like i want, and i reflash BlackHawk Kernel by Ketut. (Thks Ketut).
In pic, at 01:28 i reflash BlackHawk Kernel, before i'm using The Ace Kernel Beta 3.
does it really improve the battery?
"Perform shallow discharges. Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table at the right, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio)."

Hello guys,
I flash twice my Xperia U to ICS and I done it well. At frist one, i made without reset factory and the second one with reset factory.
In both cases I got the same problem.
The ICS is draining battery life hard, even in stand by. No mater what, It consumes about 25% for each 4h. Using hard or using nothing.
I instaled GSam Battery Manager and it says its Kernel and Android OS.

When I used gingerbread, my battery lasted almost 2 days easily.
Android version 2.3.7. It lasted 41h and still have 19%.
Please, someone can help? I tried everything i know. No matter if data or wifi is turned on or off, it will consume lot of battery. I tested.
It seens impossible to reach 24h in this situation.
Same here
New ICS su.....
I'd uninstall the task killer and battery defender to begin with, they will drain your battery like crazy.

Try using titanium backup
Freeze all the applications and services which you are not using..
If u do a thorough search in the forumyou wil find the list of services which are safe to freeze
Set maximum cpu usage to 200mhz when screen is off..

Yes definitely u need root
I'm not using my U yet, got a sim in it, but still using my old phone for now. I'm running ICS and am getting 12-15 hours battery with less than 10 minutes use. The rest of the time it's in standby, there's a pretty bad battery bug, I've not figured out what causes it. On GB I was getting 15hours medium use (~3 hours) and would still have 40% battery left. Battery info is showing it as awake the whole time it's on standby.
My phone`s original battery lasts for one day in normal use. I bought a 2680mAh battery in eBay and now I can use my phone all day long without any problem.
Just wanted to share a funny screenshot I have taken a while ago while using a JB/ICS rom (Can't really remember which), the screenshot is of the battery status in settings showing some seriously odd info (BTW, I haven't charged the mobile at all during this):

Nah, didn't switch battery nor charged it, I simply unlocked my phone to find it at 0% and shutting down, when it turned off I tried holding the power button again (because I was sure it was charged) and then it turned on with 1% and then kept increasing till it reached the flat level and then proceeded to decrease again!

The battery works perfectly normal now, and during that day it continued to work normally after it reached the flat level (it decreased as usual after this). I know, it's crazy!
mine did that too. till 13% to 94%. I removed the battery and put it back in.
I guess sometimes the battery sensor goes cuckoo haha.
Even my battery on ICS increases sometimes

we use a lithium ion battery and so when sometimes u just keep your mobile stable for 15 mins the ions generate itself and the battery increases
I have seen my battery from 76 to 85 (in 1.5 hrs )

Well, I don't know if this helps much, but I've rooted and disabled quite a few background apps. I currently have a little over a gig of RAM free. Anyway, I have 77% battery left, and I have a screen-on time of 41 minutes and it's been 8 hours, 36 minutes since I last charged it! For me, battery life has been a dream.

Now when you are pushing these times. Please state lte or wifi. If it's wifi it's not impressive

I am unlimited data. Don't use wifi. That is pure 4g.
Yesterday 5:14 screen on time with 13% Battery left
That's with all Syncs are manual (other then work email once per hour) and only air call-accept and quick glance on, all other motion and gestures off
Thats all mobile man 3g/4g i just keep all the goodies off and keep screen auto or even lower. Sync off is importent to. I also use the power saving mode sometimes and it does not impede performance much. Not noticable
got 16 hours out of a charge last night, on screen time was about 3.5 hours
