The battery life isn't as good as the 6, especially the 6 plus but it'll last all day with light usage. It runs iOS 8 great, with minimal hiccups. I expect when iOS 9 releases it will run a bit more sluggish. This phone will be a great option until late 2016 after that the software will most likely hit it's planned product obsolescence. If you're looking for a short term phone or are in between phones this is a great option. If you're a basic user that doesn't need a lot of storage this is also a great option.
