I am totally disappointed. My Ipad Air 2 was used until 11.30 p.m. last night and the battery level was about 50%. But this morning I can not turn it on. I have tried to charge it but there is no positive signal. I have just bought for nearly 3 weeks. I can not believe that a flagship table of Apple is easy to die like this. A BIG QUESTION MARK ON APPLE'S QUALITY ?
