O no, not another battery question. My apologies. I have a 4S and noticed recently that after about 5 hrs of light use, the battery is completely depleted. Pressing Home button does nothing. Never even get the "Less than 10% left" warning before it shuts off. Ten minutes on the charger and the screen comes back and battery shows ~ 55% charged. Obviously none of this makes any sense. Has anyone seen anything like this before?
