Hey guys, so I attempted to fix a cracked screen on my mothers iphone. This was the fourth time she did it and so I went back in it and did the job.

It was only after that something weird happened, due to how much I kept opening and closing the iphone up, and removing the battery and re-applying in the process. I believe I may have damaged the battery connector terminal on the motherboard.

What is happening now is that you need to pop in a fresh battery that was from another iPhone. Else it will go through a bootloop and never start up, I believe this is because of battery drain.

When the new battery is in, the battery percentage is very wrong and resets don't fix it. A few hours later, and the battery will die, and the phone won't turn on unless you put a freshly charged battery in again.

The battery terminal connector 'looks' fine, but I believe something pulled off.

I have a solder station etc. Would I be able to just resolder and solder the connection?

I know about how the solder pads and internal copper wiring work a bit, and do realize that I may be only soldering the pad and not the internal wiring and thus it may still not work.

From this link, can anyone give me instructions on how I would test the voltage to make sure, and which prong is most likely the broken on?

I'm a complete idiot with a Multi Meter and barely know what goes where unless the instructions are very specific.

Any help is much appreciated.

And yes, I know of the last ditch effort of compressing the battery connector terminal with another item, but that is a last ditch effort of course.

Thank you guys very much.
