iPhone 7 which is dead

i have an iphone 7 which is dead i tried everything i could but nothing, i measured every single caps on the board but no short and ,also i did connect it to a power supply zero amps , but when tries to boot up it goes up to 0.06 or 0.07 ma and stays there

i was wondering if someone can help ,also i measured voltages from PMIC

all the rails have the right voltages :{

and i tried to make it hot with power supply but as the currents consuming is very low it doesn't produce enough heat

thanks for reading :)
