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.

Battery at 111%

Does anyone else get their battery over 100 % ?
I believe its only a JB thing.
I've seen it on ics as well. Don't know what causes it. Been a while.

It's really odd. Isn't it a problem with calibration? Do you use the original battery?

Happened to me with or without calibration.
With and without calibration, and on the stock battery.

Known issue. Does not appear to impact functionality.
Which ROM are you on?
I'm on cna, and the OP looks like they're on cm10. It drops immediately to 99 when I unplug. Doesn't cause problems or anything.

Anyone have this problem?

I'm not even sure it will show on the screenshot. Grey horizontal lines along the bottom of the screen. Sometimes it is an opaque block. The screen is still responsive underneath it. A soft reset improves it. But it's getting steadily worse.
Thanks.

If it's not showing in the screenshot then it's probably hardware related.
Hey, thanks for your reply. Hardware as in unfixable, does the screenshot seem OK to you? I can't tell as I permanently have the lines.

Screenshot is perfectly fine.
Seems like your screen is starting to die....
Does it seem like the lines are better when you turn on the phone after being turned off for a while....??
From my experience when a screen goes like that it will get worse the warmer the device is..
If your still under warranty send it off for repair and it won't cost you a thing.

Yes, that's it exactly. Not under warranty and screens cost £150!

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
Sent from my GT-I9300 using xda premium
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.

Heating issues

I just switched from the note 2, and I've been using the dna for a couple of days now, I've noticed the phone gets very warm I was wondering if that's an issue with every dna or just a defective unit. Maybe it's a problem with the s4 pro cause I never had this issue with galaxy s3 or note 2

No same apps I had on my note, just finished doing the update to the newest build hopefully that fixes the problem

My girlfriend has a Note 2 and I've compared battery temps and cpu temps. The DNA has always felt a lot warmer at equal temps. I wouldn't call it an issue though.

[Q] DNA Overheating issues

Anyone else have issues with their phone getting super hot? Mines been up to 46°C, just from using it for about an hour. Its not rooted or anything. Completely stock.
Sent from my HTC6435LVW using xda app-developers app
My phone did this last week. Im rooted and running CM10 had been for like 2+ months. I made a call on the speakerphone and the phone got extremely hot then my speakerphone blew out! Ended up getting a replacement.
Sent from my HTC6435LVW using xda app-developers app
Is the phone not being used or are you doing anything when it gets hot. This phone for me anyway hasn't gotten nearly as warm as my nexus 4

Mine gets up in the high 30s low 40s with normal usage.. pretty sure this is recent. Anyone want to trade a good DNA for cash haha I will probably sell this on swappa and get the One when its out for big red.
