My Moto Razr Maxx is a bit on the large side, and it's no longer state of the art, but it does pretty well for battery life. Even with wifi and mobile data and GPS and bluetooth all turned on, and in active use, it will still last a day and a half. That's not as long as I'd like, but it's better than the barely-a-day that I get with my work-issued Samsung G6 used more lightly with only one of wifi or mobile data turned on at a time (both on concurrently will cut that by half because Samsung royally FUBARed the radio design). You can probably find a reconditioned one for low $$$ and it's a decent choice.
