Hello guys, I am very disappointed with the endurance of my new device. I dont play that much with it (ca. 30 Min a day), surfing the web and Appstore (ca. 30 Min over the day) and emails (automatic 15 min request). The device dont really last much longer than one day - IS this NORMAL? Or is my accu broken and I have to displace it. I mean hey this is a new device... Is retina eating that much energy How long is your battery capacity and what are you doing with it!?
