iphone 6 tristar
hi, i did s tristsr repair on a phone that didnt draw any amps. so far so good. i plugged the charger and it drawed about 0.9 amps which is perfectly normal. after the phone booted the amp draw dropped about 0.5 amps on a nearly empty battery. i thought that the battery should be in fault. i tested with a new one. still the same. i then suspected the battery line. did diode messurement 0.445 wich is also normal. changed tigris just to be sure, still the same. changed tristar again but the same. it shows the charging icon but it charges very slow. did you ever experienced that?
Yes, sometimes aftermarket charge ports will cause this problem. Also, I would test with multiple ammeters and multiple cables. Last thing to check is the middle pin on the battery connector. They are very fragile. Try pushing the middle pin outwards with your tweezers or a needle, so that the middle part sticks out a little more. This ensures proper contact with the battery_swi line, which is necessary for full charging.
