I plugged in my phone last night and made sure it was charging, so i wake up this morning and i unplug it and it was at 20%?!? So i plugged it in rougly an hour ago and it only went up 20%, could it be that i left the desk clock thing on all night it just used more than it could keep up with and my battery is just super dead? I have also used different chargers and nothing worked.
