Chosen Solution
The battery connector on my iPhone 6s logic board has partially snapped off. It presses back into place and the battery connector snaps into it solidly. Yet when connected I get no power, so clearly the connection isn’t there. I have a soldering station though I’ve never done microsoldering, or would this be possible to repair with a reflow? Sorry for the bad picture quality.
You can replace it with a hot air machine.
