buying advice for modern rugged smartphone

Jun 5, 2018
I seek advice about getting a modern rugged smartphone to survive my stay in norway.
My desired specs:
high IPxx, long battery life, very durable display, somewhat fast software, all for medium price (outrules the cat s61), no unwanted activity (buttons at the sides, outrules the dogee s60)

I do not care about:
size, weight, display resolution/quality, camera, video, games

Any recommendations? Thanks a lot!
