Only things I can think of are borked firmware (you got an OTA update that's bad), fried hardware (line spike, or something just happened to go while you had the charger plugged in) or the charger wasn't getting power, it's bad or some other charging problem that left you with a dead battery. (The last one is fixable - charge the battery for 24 hours with a good charger that's plugged into a good outlet.)
