After switching from the Nokia Lumia 925 to an iPhone 4S in October 2013 I've returned back to the Lumia 925 due to poor battery life on the iPhone 4S, and the 3.5" screen of the iPhone 4S makes the 4.5" screen on the Lumia 925 seem more like a 5" screen and Windows Phone 8.1 is leaps and bounds ahead of iOS 8.1.
