Thanks for the references. I did try most of what was suggested but too often would forget to turn one thing or another off or would forget to power off the phone and there went the battery.

Mostly where I hike one looses cell connection on the drive to the trailhead so the phone part of the phone isn’t much use. I still carry my phone, almost always off, but only use it as a Bluetooth keyboard for my Inreach, as a backup camera, for a wee bit of evening music and as a voice recorder for on-the-trail notes.

If I need to know exactly where I am, my Inreach gives me map coordinates and elevation. But, I virtually never need that sort of precision if I have a good map and am paying attention. All things considered, I view the phone as a convenience, not a necessity. On the other hand, I see the map and compass as a necessity and my family insistently sees the Inreach as a necessity.
