I just wanna share my battery care tips

Me & my wife bought a pair of ip11 .. used from the same date

but we have different charging habit

me, the most important thing = never let the battery drops below 50%.., whenever im not using it, Ill charge it  (during driving, sleep).

my wife on the other hand, just drain until 10-20% so she start charging.

here the results after 5month.

mine still at 100% health


her

my wife iphone 11 with no celular signal. try all method format, fresh install , update.

try with esim, simcard, non working.

diagnostic with machine at site no error found. diagnose online same result. reach 2 years usage, wifi work ok.

if it not software relate, what hardware to replace? ribbon? anyone experience?
