I just bought a new Xperia Play and am having trouble charging it. I've tried plugging it in to both my computer and 2 different wall outlets and leaving it overnight, but no matter how long I leave it plugged in it wont go above 48%. I've tried restarting the phone, taking the battery out and putting it back in, as well as turning off every unnecessary process, but nothing seems to work. I'm going to let it completely run out of charge tonight and see if that fixes the issue. But if it doesn't, what would you recommend I try? My charger is usb based, do you think I should buy a generic outlet charger instead? Any advice would be very welcome. Thanks.
