Most phones are ip rated in the mid- high range.
It's the battery life that let's most smart phones down, unless you look at a dumb phone (Nokia 800 brick for example).
I looked at them for quite some time, and came to the conclusion my samsung note in a rugged case suited merthyr than having an additional phone. I like the picture quality, maps and other features it offers, but carry a powerbank with me.
I Wouldn't mind a garmin inreach or similar but my current hikes and adventures don't take me too far where I can't get adequate signal on 4g/5g.
I normally have a payg Nokia 105 in the car in case of emergencies where I trash my current phone/loose it with some credit on there as a backup
