Glad you got your phone back Yard!
If I may, I'd suggest an IP68 waterproof phone pouch, or if you want to take pictures, a form fitted case; $20 to $50. They either come with or have an anchor point that will accept 20lb backing or braid to connect to a neck lanyard that will keep it at your fingertips and prevent loss. Tucked into a pocket, into a shirt, or under a pfd it won't be a bother.
A case's stick-on fingerprint feature may be quirky or quit working but I just press the power button once, quick swipe, and enter my 4 digit PIN. Takes less than 5 seconds, works every time.
Also keeping the phone in airplane mode when in poor or no cell coverage will still allow GPS for navigation and WIFI and BT for connecting devices but stops the heavy cell radio battery drain
And for around $20 to $40+ a lightweight pocket sized power bank in a dry bag or pouch will charge your phone 2+ times if you are using it for pics and navigation.
