Title:

Rapid battery drain and front mic doesn't work

Text:

Hello! I’ve got an iPhone 6s with two (I suspect) motherboard-level issues: 1) incredibly fast battery drain; 2) a non-functional front microphone (used for Siri and speakerphone calls) with quiet sound, sometimes static, and sometimes fully working audio after recording audio for a few minutes.

I tried replacing battery multiple times, but it didn’t help — this 6s goes from 100% to 1% overnight! I also tried replacing front camera flex cable (the one with front camera, ambient light sensor, and a microphone) but it didn’t help either. In both cases, I did multiple replacements: two batteries and three front camera flex cables.

I know that I’m looking for a motherboard-level repair now, but before I go to the repair shop, I’d like to know what kind of repair I should be looking for. For battery drain, I believe I’ll need to replace the Tristar/U2 chip, but I have no idea when it comes to the front microphone.
