Iphone 7 fast discharge
 

HI,

I have an iPhone 7, work well but fast discharge...
change battery .... Nothing change
when i open it, i see a lot of oxydation
when i plug it on alim, after boot ok, it drain 0.1 to 0.18A without screen on.
I haven't reference board but 0.1 is too high, no?
anyone can give me resistance value for battery and main line ?

other idea ?

kind regards

check -on time ampere on power supply it shows over ampere change u2.normal ampere shows change battery

HI

when on: 0.3 to 0.6A
in standby: 0.1-0.18A

do you thinks i need to change Tristar?
