[Q] Will taking out the battery while the phone is plugged into AC damage my s3
i had flashed a new cyanogenmod rom and i was restoring from a titanium backup, when there was an error message and the phone froze. The screen was black but the status bar was showing (and the circle for the battery was still rotating) i couldnt shut down the phone by holding the power button so i took the battery out, without realising the phone was still plugged into the wall. The screen was still showing but the battery circle wasnt rotating anymore. I unplugged the phone, restarted and reflashed the rom, everything works fine now but battery life is slightly less (before when i got home from school i would be on about 20-25%, now its about 10-15% after 7 hours) also the phone is a bit warm when playing games. My question is, have i done any damage to my phone or the battery, and if i have is it fixable or will i have to get a new one?
