SGS2 died, need budget replacement.

I don't actually use it as a phone because I can't afford a data plan that I don't use, so carrier doesn't matter as long as the device works offline.
I mostly use it for offline gps maps, games, and music/podcasts/audiobooks, with some voice calls over google voice on wifi (cell reception in my apartment sucks).

Must haves:
removable battery
micro sd card slot
headphone port
gps
wifi, 5ghz preferred.

Would likes:
16GB+
5-6 inch screen
long (8 hour+ in use) battery life
Android 5.0+

I have a tablet that I use and like, but it's unwieldy on the go, so I like using a phone as a more mobile tablet. What are my options for a low budget ($100 preferred, $250 max) replacement phone?

I really don't want another Samsung device. I've had nothing but trouble with everything Samsung.
