Your phone may heat/warm up while flashing, this is normal but excessive Overheating can damage your battery but I don't think it shouldn't be too hot to damage your phone except you are microwaving it.
Swyped from my Samsung Galaxy SII

alright thanks!

Did you just walk out of a cave and this is your first electronic device? It's normal for things to get a little warm...
Sent from my GT-I9300 using xda premium
Nothing to worry about. Most electrical items when left on get warm.

Battery

My battery isnt charging very fast at all.
Ive had it on charge plugged into the mains for 10 hours and its at 24%

I would flash back to a stock ROM and start there. Make sure it is not hardware before you start changing software settings.
Can i flash a stock rom with 9% with odin mobile lol

I'd try putting it on USB charge first. It might just be your charger has gone US rather than anything to do with the phone OS or software. Looking at those first screenshots I'm wondering about the 'discharging' 'charging' going on. To me that sugests the charger itself is not staying on charge mode.
The SIII gets 'stuck' sometimes says Samsung, they said it was a software issue so hopefully they'll fix it soon
Possible temp fix: turn off phone (works 90% of time for me)

Flashed stock ics an hr ago and I'm up to 30% that's the highest it's gotten to in the last 24 hrs. So think it's safe to say I'm back in business.
Very strange behaviour though!

I think that your charger is bad. Try some rooted jb os with latest siyah kernel,then try to charge your phone with usb. Latest syiah kernel have tweaked usb charge to 900mA. You have managed to recharge a little bit because ics has weaker wireless than jb.
Sory for my bad english
Cant be bad charger because I've tried 2.
As soon as I flashed stock t-mobile ics the charging went back to the way it should be.
Was running latest overcome jb. Was working fine. Something must of gotten corrupted?
Only thing that fixed it was flashing stock.
Anyway crisis averted. Just glad Im not having to send it away to samsung.

S3 screen lights up for no reason.

Hi guys i just realized that my s3's screen was lighting up again and again for no reason. There was no call or text. Its pretty strange and it drains my battery

Never happened to me. You don't mention anything about if your rooted or have another ROM on your device.

I have seen that happen on my s3. After a while it goes away. I had it too on my gnex. I think it's some app that is running in the background. Was concerned at first but never did anything about it. Try installing GSAM battery monitor. It shows which process consumes the most battery. There are other apps better, but this one is free.

Max battery temperature?

Hello guys,
I have one Q.
What is yours battery max temperature ?
I have instaled battery info app which has temperature indicator.
Today was almost 42Âșc.
Is this normal temperature?
I'm a little bit worried, because S3 has one major problem probably with mother board and it's over heating.
Thanks in advance for your ansvers.
Sent from my GT-I9300 using xda app-developers app
42 is pretty normal, when i play games it goes up to 48 and no problem whatsoever
Sent from my GT-I9300 using xda premium
Thanks man for your answer.
I m glad it's nothing to worry about.
What do you think is the max temperature that won't harm the phone?

Don't know but it's OK of it's doesn't reach 50 i guess
Sent from my GT-I9300 using xda premium
Normally the temp will go till 60 c. If it go above 60c your battery might have problem. The battery will broke if it too hot or it will discharge fast.

Thanks man.
This is the info that I've been waitng for.
Sent from my GT-I9300 using xda app-developers app
From experience
well i have a habit of overusing my phones capability.
the battery stop charging when it hits 60C.
i accidentally kept my phone under a pillow while downloading some stuff when i found my hand kind of burned and when i checked it the temperature was 70C
i still dont have any problem. i just removed the casing and held it to the AC for a few minutes and it was alryt.
my advice is never leave ur phone under a pillow ever again!!

Benchmark score less

My S3s bench mark score is significantly less compared to the given score. Around 900 points less. What could be the problem? Galaxy S3 India. So what do I do? I'm running stock ROM, not rooted, hard reset done twice.

Does the phone feel slow?
Nope. But a few high end games lag on playing continuously for more than 45 min. And the phone gets really hot.

Just the cpu throttling, bound to happen with a device that has no cooling, especially if the ambient temp is high

Heat is to be expected. Benchmarks dont really mean anything. Our phone is no way near high end when it comes to gaming capabilities.
But "Dead Trigger" is supposed to be within its capabilities right ??

As long as you're not adding the Tegra effects, yes it should be. I always find when hacking in the tegra capabilites, it kept freezing
