I think this factor is more relevant today than five years ago. At least my upgrade cycle has slowed down, and I'm often subjected to poor battery life before the apps get too demanding for the hardware itself. Really frustrating with non-user serviceable batteries when this happens. How a phone feels like new with a fresh new battery, that "oh my god, how..." feeling with the battery life, just cannot be underestimated.

I agree - and I think most people's upgrade cycle has slowed. Most smart phones from 2012 onwards fulfil basic consumer demands (calls + messages, nav, apps, basic pocket camera).
