How much lónger does the battery last on the iphone 5 than the 4s?

Not botherd about the extra gadgets batery life is the main thing. Is the 5 much better on the whole?

Battery life is better on the 5 but i never tested the two

I have both the iPhone 4 and iPhone 5. My iPhone 5 battery isn't that great, I mean I think it last about the same amount of time as my iphone4. I start my day at 6am- 100% battery. It is now 9:42am and I'm down to 73% with kik messenger Active and lots of texting. IPhone 4 is on 90% with only music playing. So I'd say it depends on what apps you're on and what you're doing. Battery life 10 hours max before needing charging.

Battery is a little better. It all depends on what is currently running app wise and most importantly on the network. 4g lte takes more battery power than 3G which the 4s doesn't have.

I've found that my iPhone 5 lasts about 12 hours longer (when locked/not in use) than my old iPhone 4S.
