I bought the ifix it iPhone 5s battery replacement and I hooked it up fine and it charges while the screen is not attached to the phone properly but when it gets attached it stops charging, please help??
This is perhaps a silly question…how do you know it is charging when the screen is disconnected? If you want to be certain that it is actually charging, you can use a USB Ammeter. Take a close look at the screen flex cables and connectors (on the flex and on the logic board) to see if they are damaged. They may also not be properly connected so you should try to re-seat them.
I had the same problem. The issue is that the battery doesn’t charge if the back of the battery connection cable is in direct contact with the metal battery connector bracket. In other words, the point of connection needs to be insulated. Most likely, the insulation on the back of the cable got a little messed up at some point. Add a small piece of electrical tape to the top of the battery connector socket and you’ll be back in business. I learned about it here: iPhone battery not charging after DIY battery replacement. Why?
