iPhone 8 plus 1% battery after LCD replacement
 

Hi,
I have the iPhone 8 Plus after the lcd replacement but unfortunately the phone shows 1% battery - but it doesn't turn off or signalize low battery - it means the battery is still charged enough.


Have you ever seen similar issue? do you know how to solve it?


thank you

Hi. Check battery connection, maybe pushed back halfly.

hi check q3200, q3201 and xw3370

Hi, thank you but no success...

Hi, checked q3200 and q3201 - there is a PN junction between pins according to schematics so I guess the could be ok.



XW3370 - I don't really know which part it is...

I need to solve it, phone is not also charging so customer cannot use it...
