My phone battery works well, but it is very difficult to charge. I have tried with several cables, and every time I find a cable which seems to work well, after a while it doesn’t work anymore either. Now I have one that I have to hold in a very specific position to allow it to charge, but I don’t know how long it will last. What do you suggest I do? Thank you!

change the dockconnector and your phone will work again

It seems your lighting cable connector on iphone side is expanded. use some tape on your pin and insert so that it can firmly hold inside iphone connector point
