Hello mon2,
thanks for your anwser, i don't speak english well but i try. Yes its very good idea and you have wright i go to change this resistor by another same like i2c line.But with zillion xzz i don't understand why have boardview but not schematics. its abnormal.
Big thanks i go to test your way ans reply after. Have i nice week

Hello, I soldered 2 1k resistors it's true that on these lines there are 1k resistors except that it doesn't work. These are the resistors on the I2C gasgauge and SDA lines resistors near the battery connector of the 2 thin pins. The iPad Air 4 turns on and restarts alone, and stays on 0%.... I think battery has a problem too maybe...

Do not see a schematic in my database but only boardview file. The 2 caps in the same region are each linked to the PPVCC_MAIN_LCD_SW rail. You can study other available schematics to review which caps are present there and this board should be similar. These are bulk filter caps for the power rail.
Suggest to source:
10 uf, 6v3 rated or higher voltage 0402 X5R ceramic capacitor
10 uf, 6v3 rated or higher voltage 0603 X5R ceramic capacitor
10 uf, 6v3 rated or higher voltage 0805 X5R ceramic capacitor
Each should be low cost from Digikey / Mouser / Arrow / RS electronics. Grab a few of each since they are easy to lose when mounting. Only one will fit inside the PCB footprint. These caps are not polarized so no polarity to the mounting direction.
