My son and DIL bought new Iphone 5's about 3 weeks ago, and both need charged daily. they both had the 4 before this and didn't have this problem. is the new battery just not as good or is it something else?
These batteries get better over time. I remember my iPhone 4S battery needed to be charged about twice per day when I first bought it, but it's lasting almost 30 hours on a single charge now.
