iPhone 8 plus 1% battery after LCD replacement - GSM-Forum

MaClaud1 · 06-04-2018, 13:13

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, 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...
