or just like the vision pro - a wired external power pack with a proprietary connector to the iPhone, but USB C on the power pack :D

Try cleaning it. I used to have the same issue, and had to get the subboard replaced multiple times too, until I realized that mechanically cleaning it with something really thin works as well. Felt really dumb after finding out lol. The pocket lint can absorb moisture and then the sensor doesn't work properly.

It’s counterintuitive at first, but using hairspray or 3DLac can really help to prevent the print sticking too much. Or can help it stick more, if needed, just like magic. But weird that it happens to the OP with PLA, usually PETG is the problematic material that sticks too much, not PLA.
