Hello, I got the HTC one today, just a few hours ago, actually. The first thing I did, as I do with most electronics was drain the battery completely, then recharge it to full. I don't know if this is still recommended, but I figured I may as well to be safe. I drained the battery completely, then plugged it in to charge. It's been there for about 15 minutes, but I can't figure out how to turn it have on now, please help!
