Longest battery life

If you buy through a link here, the store pays me a small commission. Your price stays exactly the same. How that works.

My short take

GSMArena measured 21.6 hours of active use, the longest of any phone here with a score, but there's no telephoto camera and GSMArena called it pricey at launch. I'd buy it if battery life is what you care about most.
