AT&T S3 not charging when screen is on - Galaxy S III General (US Carriers)

My S3 has started a strange charging problem and I hope someone here can help. My S3 has been charging fine and showing the LED, but since I plugged the phone into my laptop USB, now the phone stops charging if the screen is on. It doesn't matter if it is connected to a wall outlet or USB.....turn on the screen and the LED goes out and the unit stops charging. Under "Battery" options in settings it shows as connected and charging, but it isn't actually charging any. Use the power button to turn off the screen and the LED lights back up and the unit starts charging for real. I've turned off the LED(unchecked it) then turned it back on....no difference. Rebooted etc.....nada.
Phone is bone stock AT&T and I'm new to Android. Hoping it is a simple setting that somehow got changed.

Led is supposed to turn off when charging and screen is on.

You misunderstood part of the post. Not only does the LED turn off, it stops charging with the screen on. Under Battery options it "says" the battery IS charging, but it really isn't. Battery level continues to drop. Turn off the screen and it starts actually charging again.

Well it may be because you are using more power than its putting into the phone. Or it may just be defective. Have you tried another Rom yet?

Are you using the USB cable that came with your S3? Is your laptop plugged in our running on battery when this happens? I also believe that you might be using more amps to run the screen and Wi-Fi and whatever else is running on the phone than the USB can output. What generation USB port is in your laptop?

If there is a thunderbolt on the battery icon, then that means it's charging. When you turn on the LED option when charging, it only turns red when the screen is off, and turns green when it's full.

Phone shows green battery but wont turn on after charging

I currently have a stock standard SGS3, when i put the phone on charge, and leave it the green led eventually shows, i then press the power button to wake the phone and i see a green battery. At this point i cant do anything swiping doesnt do anything and the phone then shows a black screen. I then need to restart the phone. Has anyone else experiencing this issue?

It sounds like your charging the phone while it's switched off. Just put it on the charger without turning it off.

when the "green battery" shows, reclick (hold) the power button again, it should boot.
When the phone is off and you charge it , it shows that animation.

Thanks I have no problem booting the phone from the green battery icon. My problem is that i charge the phone while it is on and for some strange reason it switches off when it is fully charged, surely this is not normal.
I normally leave my phone charging overnight and when i wake it the morning i have to reboot from the green battery screen
This does not happen all the time, and i'm using the standard samsung charger
Your phone may have a problem due to excess charging where something freeze it down after the normal three hour charge .
See what happens on a normal charge .
Otherwise return under warranty .

Phone won't charge or turn on

After flashing Quarx's JB 25.10 rom, my phone ran i to trouble. Now, it won't boot. I when I plug in the phone into an outlet, the charging light won't come on but oddly, the phone turns on and goes to the Motorola logo at boot. Then it stays there. I've since lost the original cable that came with the defy if that matters. When I plug the phone into the USB of my computer to charge, the charging LED comes on. But after some time, the phone turns on and goes to the Motorola logo and stays there with the charging LED off. Some time latter, the phone will turn back off and the charging LED will come back on. And then the cycle repeats with the phone turning on to the Motorola logo.
When I hold the up volume and power button, I get a message saying battery is too low to program so I can't even get to flashing a new SBF from RSDLite. Help?

Had this problem with first 2ndboot builds, but it should be resolved in later updates... For me charge mode works fine on 10.18 +10.25update.
Anyway you can try starting the phone without the battery, with moto charger:
1: pull out battery
2: connect charger to mains
3: connect charger USB cable to phone
4: phone should power up automatically, and boot to CM10
5: once the phone booted to CM10, you can put the battery back, and charge it
This method worked for me, hope it will work for you too!

It's stuck at the Motorola logo. After I had the problem, I reinstalled CM10 but the phone abrubtly shut off mid install. That may of caused some problems.
Charge the battery with desktop charger first...

You mean a computer USB to phone USB cable charging? That doesn't help. The moment I plug the phone in, the white LED ligth blinks once quickly but the phone won't even turn on to the Motorola Logo.
No, he means a separate batt charger, where you can put the battery in.

Please ask all questions in the Q&A section. Thread moved there.
So why would flashing a custom ROM cause problems with charging?

can't charge turned off

I'm running cm10 on the internal storage, and when I plug it in while turned off, it just boots. Normal issue with cyanboot?
Normal. It turns on because software has a role in charging, so the power chip turns it on when plugged in.

Nexus 4 Died?

So i was playing a game called The room battery was at 1% but was connected to a charger and it suddenly powered off and a red light started to blink then the light disappeared and now it is connected to the charger and has no response, is my phone dead? :S i'm so nervous.
The device may not respond until it is fully charged. I think it's best if you wait until it's charged fully and see what goes from there.

Maybe it's the adapter that's broken? Try changing adapter/cable or try charging using your PC

So many threads on this. Charge your phone overnight. Not working? Rip off the back cover and disconnect and reconnect it. That's a no go? Check another thread.... Wish you luck

When I have get the red light I have to keep trying to power it on taking the charger in and out. Last time took 30 mins for it to go away of continuously trying to power on and taking charger in and out. The reason I do this is because if you leave it on charge with the red light on the phone will not charge. You can leave it over night and the red light will still be there and your phone won't be charged! It will only charge if you get the charger screen up and the red light is off.
Happens to me if don't have much battery and I try to watch something on the TV with slimport connected

plug it in, and press and hold volume up plus power for 60 seconds, then release. It should then power up automatically or press the power button again. This key combination is the equivalent of a battery pull, which is what you have to do when it gets locked up like that or battery drains too low.
none of those worked i tried it's bricked i guess

Your phone's fine. The reason it powered down even though it was plugged in is because it was at 1%, and considering you were playing a game your phone was probably expending power faster than it could charge.
When there's absolutely no power left it won't respond no matter how long you hold down the power button. Just plug it in & let it charge for a few hours don't worry.
source: this happens to everybody who uses their phone extensively at some point

It's not bricked, there are a lot of threads about it around here. You have to charge the battery, and keep trying with vol down + power, until it takes you to recovery. From there choose reboot.

you have to disconnect the battery and charge it withe external charger for an hour then reconnect your battery . i hope this help you .

Nexus 4 Power Issue

Hi, I have a Google Nexus 4. For some reason, the phone will not turn on. It is fully turned off, but charges properly. When connected to charger, it displays the battery charging icon, but when you hold down the power button, nothing happens. The battery seems to be charging properly and the display seems to be fully functional as well. There is no root done on the phone or flashing. The phone has never been worked on before, does anybody have any suggestions as to what it could be? The power button clicks properly but I cannot turn on the phone at all, please help.
How much is the battery percentage? And is your notification light blinking red? And when was the last time you used the phone and what was the last thing you did?
The last time i used my phone was over 8 months ago, the battery indicator on screen shows around 80% which was definitely charging, it was dead to begin with and i left it charging for an hour nd a half before attempting to turn it on. There was no red light on the notification that is typically set when the phone is on and charging. The phone is completely turned off. And when charging doesn't show a light.
