I used a ton of apps this weekend for the first time (Nokia Drive, Nokia Music, Fruit Ninja, Baconit, Nextgen Reader, Skype, and a few others), but the WORST for my battery and heat of the phone was Minesweeper. I've never seen anything like it. Within minutes of starting it up the phone was noticeably warm and the battery was draining quickly. Other than that a great weekend with my Lumia 920. The camera accessibility & quality is fantastic!!!
