Bough my Inreach mini a couple weeks ago. I just got home from a 4 day bear hunt.

Over 4 days, my mini was:

on from approx 0630 to 2200 daily,
Blue tooth mode on,
Track mode on for the trip to and from camp, off the remainder,
Sent 4 custom messages per day,
Received 4 messages per day,
Half my messages were while the unit was synched to my phone,
Battery today when I got home was 60%.

My normal trips wont be more than an ok message in the morning and evening with the unit powered down in between. Figure I can easily make a 7-10 day backpacking trip.

Was cool to be able to tell my hunting buddy what I was seeing and where.

I left it turned on to see as dont intend to strut around with it on all day. Figure turning bluetooth mode off will save additional power.
