Is there any way to charge a bare iPhone 4 battery directly?
My iphone 4 does't charge nor be recognized by computer. And I tried to replace the battery but it did not help.
I checked the answers here and I guess the issue is probably cased by the components (USB fuse or power management IC) damage. It is far beyond my capability to replace the components by myself...
So I give up to fix my phone but just want to get my iphone some power so that I can turn it on and backup the important information still in it.
I am wondering if there is a way I can charge the bare battery directly without the phone, then I can put the battery back to turn the phone on?
The method is not necessary to be perfect, I do not care the operation may affect the battery life (I will get rid of the whole phone after I get the information in it anyway). Any method can get the battery some power without the phone is welcomed.
Is this a good question?
