All new smartphones are getting pretty mature as far as each of their operating systems is concerned. We are now on the 5th Revision of IOS. The 4.0 release of Android with Ice Cream Sandwich and the Second major release of Windows Phone 7 with Mango. Many of you have asked or requested that I make a comparison video between all the new platforms. After thinking about how to do this best and most objectively I decided to break the comparison into segments. Each segment will cover one topic or area of the phones and show a comparison of how each of them work. In this video I cover how Battery life is on iOS5, Windows Phone 7 and Android 4.0 Ice Cream Sandwich. I also go over the options for each of the different devices. Thanks for the suggestions and as always comment below on which platform you would choose any why. Please be objective and not a raving fanboy (although that can be hard).
