I just used my Garmin InReach SE (yellow one) for 11 days in the Stone sheep country. I would turn it on several times a day to send texts and receive messages. After over 400 texts (incoming & outgoing....realize that many 160 character texts get broken up into 2, 3 or even 4 shorter texts for whatever reason) during that period I was at 50% battery life. I haven't used a mini but they have 1/2 the battery life rating (50 hrs vs 100 hrs with the larger unit). For me the mini would be great as I navigate with the phone and turn on the InReach to communicate). Many of my messages were sent out by texting on the InReach directly to save the iPhone battery. Slow but it works. Between my buddy and I we had one small charge stick for our iPhones and used the little charge pack up (it was 5 years old and I should replace it). I really like the InReach!
