I don't own a car and walk a lot. I also have a very limited amount of bag space- I carry a small bag that can't hold much more than my computer, phone, and wallet. Being able to have my phone run all day long without hassling with carrying a spare battery is nice. Right now my 5 does okay; it usually only needs a recharge on a day when I spend a lot of time with terrible reception. But it'd be nice to not have to hassle. And... well, I really love not having to carry a power brick for my Air any more unless I'm going on a multi-day trip. One less battery pack and cable in my bag would be a nice thing. Less is more. When I get around to switching to iOS9 (I like my jailbreak), I'll probably use low power mode a lot on days when I know I'll be draining the battery.
