I have a user who just got a brand new verizon 16GB 4S. However, for some unknown reason, her battery is draining completely (or very well near it) within an hour. Here is a summary of her settings- ZERO battery heavy apps installed (she really only had two apps-flashlight and NPR, but NPR was not running when I looked at it. Wifi Turned off screen brightness at 50% location services off only apps in notification center were mail, calendar, reminders, messages and weather. She does have an exchange email account. It was originally set to check for mail and pull it every hour but i have now set it all to manual pull. This is the only thing that I can think of that is battery draining but its not like she gets 2,000 messages a day, so I am hoping that setting it to this combined with the settings above will help. I did not check for an iOS update-though she did visit an apple store over the weekend, so i assume they checked it and updated if needed. My gut is telling me its a lemon-i have never heard of any iphone (or really any phone) draining that fast while not doing anything that even remotely considered battery intensive. anyone have thoughts?
