I recently notice something strange with my 3rd gen ipad with retina display. While being charged directly from the power outlet, the ipad does show the charging icon on the top right corner. As soon as I start using it while plugged, the percentage starts to diminish. Is my ipad a bad one? do I need an replacement. I have included some pictures showing what transpired from 6:28 am to 10:51 am. My ipad was plugged all this time and I only had it showing the main screen while conducting this test. I am still under warranty as it has not been a year yet. I bought it brand new from Bestbuy as Apple was sold out of the black model 32 gigs. I completetly drained the battery, recharge to 100 % then let it drain and recharge it to 100% to calibrate the battery and it still does the same thing. I have the latest update 6.1.2 I would appreciate if you could give me your honest opinion as to what to do. Thank you.
