I bought my iPad 2 in May, and everything was totally fine with the battery. Over the last 6 weeks however something weird has been happening... the battery appears to discharge normally during use, but as soon as the level reaches about 20% the iPad shuts down as if the battery has completely run out.
When I plug in my charger, the iPad shows the empty battery symbol until there is enough power for it to boot up again (again, as it should); however when the unit powers up again the battery level shows up as 20-22%...
Anyone else having this issue? Or should I just go back to the Apple Store and demand a new iPad!?
