Hi .. For the past few days, on several occasions (but not all of the time) my screen is not going off after the time limit I have set, which is one minute. I check the phone and then it's left in my locker at work. As I hadn't realised the screen was staying on, this plays havoc with my battery, which is only lasting about 6 hours. I understand it's probably caused by a rogue app, but I haven't a clue which one .. nothing seems to be running. What do I need to do, to track it down .. Thanks.
