I have an iphone 5s drawing 0.08 amps. I had replaced the 5s tristar with the backwards compatible NXP 610A3B chip that i ordered from the Rossman group. This worked for one charge, then the phone went back to 0.08 amp draw. So i replaced it again with the same result. Ive checked for shorts and most outputs around the PMIC. Where should i focus to get the phone charging and functioning again?
If the same issue happen after the tristar replacement that must be other fault.Check all pad below tristar and also check the SWI line and see battery data present on 3uTool or not.Yes most of the Tristar is common in iPhone.This will help to find out the compatibility of Tristar.
