Water damage, repaired, new issues arose.
On Tuesday I had someone ask about his iPhone 6S Plus which had a nonfunctional ear speaker. (Speakerphone and mic worked, just no ear speaker.) He claimed it stopped working when it got wet. He needed his phone that day so he didn't give it to me then, but today he returned. Not only was the speaker dead, but now his screen was also dead -- heavily distorted, shifted to the side, wacky digitizer. I replaced the screen and the ear speaker; I've done this many times before without incident.
Upon reassembly the screen works fine but the ear speaker still doesn't work, and now a new problem manifested: the back of the phone (the upper part) gets pretty hot, and the battery drains INSANELY quickly -- like from 50% to zero in the space of fifteen minutes. I watched the percentage count down step by step. The Lightning port seems to work properly; it knows when it's plugged in and there's power/data to/from the phone, no problem.
Anything I can do to address this?
Is this a good question?
