回答“What counts as unrepairable? (PS4 Controllers)”Use the defective ones as "remote PS4 power on switches". Solder a pair of wires to the PS4 wake/menu button and then connect to an Arduino. It's pretty awful you can't turn on PS4s (or wake them) using third party remotes. I'd sacrifice/hack one of my own PS4 controllers, but they're in perfect shape still (and expensive to replace).
