IPhone 5 battery life review?

How good is the battery on the iPhone 5, last years model?
I'm getting the 5S which will be improved because of the lower power consuming processor, and the larger physical battery. But on average how well was the iPhone 5 battery? Better than the iPhone 4S? How many hours of mixed usage on average?

I'm not really sure how many hours exactly but I know for a fact that my iPhone 5 has a 100% better battery life than my iPhone 4s! Hope this helps a little!

Iphone 5 battery is pretty good. NOT stellar, but good. It has a 1440 milli amp hour battery. It is a rather small battery but apple's UI is pretty battery friendly so it lasts. It will probably give you around 8 hours of moderate use and 6 of hard usage. The 4s actually has the same size battery practically (1436 mAh). You might notice a slight increase in battery life in the 5s due to software updates but nothing that good.
