I dropped my phone in water 2 months ago and i got it repaired I replaced the battery and now it is overheating and dying quickly I don’t know what is wrong with it because the guy that fixed it said I should have no more problems, anyone know why it could possibly be doing this? Also the Touch ID has stopped working.

Could be a short on the board. Do you know if when it was fixed, they cleaned the board with alcohol, or preferably ran it through an ultrasonic cleaner, with shields removed? If it wasn’t cleaned or if the shields weren’t removed, there could be corrosion.
