Tbh, theres no point in asking, you'd be better going to a shop and having a shot of each. You'll just get different stories. I have an iphone 5, used to have an iphone 4, the battery life wasnt alot different for me tbh. And ive not had any problems at all. The app store has a ton of good apps, both free and not free. Its totally your own preference. Im not a fan of android as i dont find it as user friendly and easy to use. But i wouldnt say it was bad. The size of the samsungs was a big turn off for me as well. But go have a shot of each. Ignore the fanboy bullshit tbh, it'll just make your decision harder but 90% of it is exaggerated. Like i disagree with studoc post about the screens and how all the apps cost etc. iphone 5s processor is an a6, 1.3ghz dual core by the way, but it all depends on apps you use etc. ive used both android and ios. They both have pros and cons.
