Got my A500 five days ago (Acer factory refurb off eBay), got it charged and operating, it was good. Got an HC update and then a couple days later the ICS update. Finally got down to around 30% battery and plugged it in. Charge symbol on the screen had the lightning bolt through it as if it were charging and the on/off switch light was....flashing, I think? Anyway, next morning it was down to 14% charge (still plugged in!) and that afternoon it was down to about 6% (still plugged in). I tried unplugging and replugging it to no avail. Last night I turned it off at 4% and plugged it in and it charged to 15% or so (had to turn it on to see if it was charging) and that was as high as it got. Now it's back down to 4% even though I've tried the same methods again. Is this a hardware thing? ICS thing? I've only fully charged this device once since I got it so I have no other experience aside from the initial charge with HC. Suggestions? Factory reset before it's totally dead and hope for the best?
