Last night I was playing with my phone (4S) and didnt realize how low the battery got and it finnaly just shut down like expected, gives me the flashing red battery and to plug it in. So I go to plug it in and like always takes 5-10 minutes for it to recover and fire back up, but this time NO, 20-30 minutes pass and nothing, move to wall charger 2 and nothing, wall charger 3 and still nothing. Keep in mind 3 seperate wall/cord chargers that always work. So I go to bed and just kept it pluged in, wake up 4 hours later look at my phine still DEAD!! Ok so then I fire up my computer and hook my phone up and go back to bed for 2 hours, and walla--phone is back to life!! What the Heck just happened there and that does not seem right at all??
