All of a sudden my Sony Ericsson Xperia Active started draining the battery super quick and then it wouldn't charge again, even when the phone's off. I've tried removing the battery for a while and it again charged it but again it didn't last long because it drained it super fast and after that it again wouldn't charge anymore, I tried replacing the battery with a brand new one I just purchased but it was the same thing, so I know the battery is not the problem, I also used different chargers so I know it's not that either. I don't think it's an app or a virus what's causing the problem because like I said it still drains the battery and won't charge even when the phone is off.
The only thing you could do is to perform a system repair and if that fails then I'd surmise that you have a hardware fault not related to a defective battery or charger as you have tried new and other cables
The Xperia Active was released more than 2 years ago, it makes sense that you might need a new battery
