iPad 2 restarting intermittently and very slow to operate and charge
I have an iPad 2 (Model MC769B/A) running on iOS 6.1.3 (10B329) and over the past few days I have experienced very slow charging times when plugged into the usual source - the main wall socket.
Also, I have had a number of intermittent restarts even when I am in the middle of something. The screen just goes black and then the apple logo appears 2-3 seconds later and the device appears to reboot.
I have tried closing all application running in the task manager (double clicking the home button) and doing a hard reset (holding the home button and power button) but neither seem to have any effect.
I'm also noticing that the power the device holds is erratic at best, as I had zero charge this morning - completely flat, no power - at then plugged it into the wall and after 5 mins it was at 36% then after 2 mins was at 18% (!).
Does this sound like a hardware or software problem? What else can I try to remedy?
