Smart phones with better battery life?

[AC Question]

My employer provided phone gets OK battery life. Which smart phones are know for getting the best battery life available? Preference goes to Crickit and Boost Mobile phones as those are the providers that I am considering.

I'd say the Asus Zenphone 2 Max is right up there with a 5000mah battery. The S7 Edge already has great battery life and that's only 3600mah.

Or you could just get a power bank for less problems.

Power bank for the win. 5,000 mAh or more (up to 20,000 mAh - Anker) in your pocket. That's a lot of battery life.
