When iPhones battery drains to nothing, I cannot charge it
After disassembling my iPhone, i noticed that if the battery drains all the way out and it shuts off because of it, and then i try and charge it, i just get the low battery red icon. It will stay like this forever no matter how long i charge it.
I figured out how to fix this problem temporarily until my battery dies again. I take apart the phone and if i disconnect the battery connector from the logic board and then reconnect and reassembly it will work. Does anyone know what is causing this problem?
How could i fix this?
