hello the team
I have a problem with my iphone 7 the component U2 was broken
I change it
but now the phone is rebooting but the battery percentage is misleading (it goes from 1 to 100%)
I put it down and then turn it back up to 56%
when I test with the multimeter the value is of 3.7V
i have replaced the battery but the problem is still

Brother that is SWI (Electric quantity detection) pin fault.There in iPhone so many small ic resistor works for that.Sometime while open screw also that parts makes damage.
In my suggestion.
Check the battery connector SWI pin in a good condition.
This flactution on battery percentage not issues to Trister but might be in Tigris and that is also a charging ic too.
Check gnd resistance on Bsi might be open or damage from swi to tigris.
这个答案有帮助吗？
Follow that line mark on red
