Hi, I was repairing a customers phone. They described the phone getting stuck in a boot loop coming on in once a while and then it would get stuck in a boot loop again. The back of the phone got quite hot so I guessed it was a faulty battery. I took the battery out and as soon as I disconnected it, it started to smoke. I’m worried the customers phone could be damaged. The new battery is coming in 2 days but I’m really worried the phone could be damaged. Need some answers to help ease my conscience. Thank you!
As long as it was smoke coming from the battery and not the logic board it should boot up fine. If you have a multimeter you could check the main power rails “PP_BATT_VCC” and “PP_VDD_MAIN” But it won’t hurt the phone by replacing the battery.
Carefully, wearing gloves and eye protection, get the battery out and into a bucket of sand.
