Battery not holding a charge.
So this might be a bit long winded, but I want to give every detail I can because I’ve been searching for an answer online and I have not found one. So I have 2 PS4 controllers, one I don’t use because the left analog stick doesn’t work. I bought a new one about 10 months ago and recently it stopped charging altogether. I did some research and came to the conclusion that it was either the battery or the charging port, so I went ahead and swapped the battery and charging port from the old controller with this one. Now I can finally see the flashing yellow light signalling that it’s charging, but the battery is perpetually at 0%. It’ll work plugged in, but instantly dies when unplugged. I’ve tried swapping the batteries back and nothing changed. I don’t want to say it’s impossible, but it seems a bit farfetched for both batteries to die at the same time as the newer charging port. I’m not sure if this info is relevant, but when I unplug it from my PC, I get this perpetual red light that stays on for about 10 minutes or until I plug it into my PS4. Another side issue I want to mention is that while it was plugged into my PC, it kept registering that I was holding up and left for some reason.
