I am very confused. Last night my Archos 80 G9 was on 56% so I placed it on the charger. Not the one that came with it. This morning when I woke up and checked it, the battery was COMPLETELY drained. It was at 0%. I know that the charger cable and plug I used works, it is used often. I can understand the charger not being plugged in, but discharging the battery to 0%?
