I dropped my iPhone 5 and cracked the screen. Even though I was waiting for an iOS phablet, I decided to order the 5S. Having used it for three days, I have to say that it is the finest smartphone I have ever used and I have used almost every one. The screen is great and the camera takes gorgeous pictures but it is the battery life.The battery life is so good compared to my iPhone 5 that I have ditched my Mophie case for emergency use only. Having a small phone is great. Having a small phone that can let you create a talk on keynote in the middle of the night and have enough juice to last the day is phenomenal.
I don’t know why it works so much better but I suspect it has to do with the 4G radio and how the iPhone alloys juice to it. The phone clearly can get through my 12 hour day now with juice to spare.
