I bought a controller for a long time and it broke after a while. I think the battery was defective. I sent it back and now it is causing such problems again only that I think the battery is full. So I can't operate my controller without a cable on the ps4 or pc. When I unplug the cable it flashes red briefly and then goes off. When I press the home button, it doesn't flash at all. It only flashes when I reconnect it to the PC or ps4. I don't think the battery is dead because the battery was recently changed.
Well, but would still replace the battery or at least measure how many volts are left on it.
I'm thinking about repairing the controller myself but I would first make sure what is broken because the modded controller is one with paddles (is not a cheat btw) and I'm considering destroying the cables that are for the paddles.
