Even if you press the home or power button, the screen will not move and you have to remove the battery. Then, when you put the battery on and try to power on the phone, the Galaxy S3 will show the boot animation logo but it will stay there until you fully charge the battery. There are two reasons which can cause this annoying problem.
Software problem
The current firmware on your Galaxy S3 can be buggy and it will act weird every time battery level is low. To fix this, try to make a factory reset. If that doesn’t fix the problem, you need to install another custom ROM or firmware via ODIN.

Battery problem
If the firmware is not causing this, then the problem is with the battery. Since the Samsung Galaxy S3 is more than two years old, the battery eventually degrades after such a long time. At first, try to calibrate the battery. If that doesn’t work, then you need to buy a brand new battery for your Galaxy S3. The old battery is degraded and will always act weird when charge level is low.
