My iPhone 4s battery connector got detached from the logoic board, after soldering it back iPhone isn’t charging and restart every 3-4 minutes like screen goes gray black and apple logo comes. I have one more battery tested with that but there is no difference. Battery was 57% and 2 hours later 40% while connected to the charge. Edit:
Have a look at the detached battery connector. Please suggest can it be repaired or not.
Your battery connector is not properly installed one of those pins is not getting good contact that’s why the iPhone is acting up good luck I have soldering those tiny pins I had to solder and resolder my battery connector 4 times to get it working again GOOD LUCK
There should be ics by the connector ignore the jumpers on the image because I can’t remember if this was the 4 or the 4s but you should have components next to the connector
It can be repaired I believe that
