iPhone 4s broken battery connector repair

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:

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

So there continuity to each pin?

Did you accidently remove any of the tiny resistors by the connector?

I ran into the problem your having and it's stressful and a pain and I noticed that 1 or 2 things this is assuming the charger and cable are working correctly was 1. Replacing battery and 2. Resolder the plug once again

I never felt that there is any resistor near the connector.

I resoldered 3 times and everytime checked i got the same issue.

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
