Hi,
Recently during 2 days hike turned my Instinct Solar to Expedition mode just to see, how it performs in it. I was close to shocked, when in ~ 36 hours battery was totally empty and Instinct turned off because of that.
I am sure, it was no other specific things/modes that time and everything else happened exactly as it should - with change to expedition mode Pulse Ox turned off atomatically, heart rate and all other features too. Recorded GPS track looked exactly as it should - one GPS point per hour, no surprises, backligt 70% and delay 8 seconds (but I was not looking at screen too often:))
Watch is just aprox 3 weeks in use, so I am slightly afraid, isn't this a case of warranty - in normal everyday smartwatch mode (HR, Pulse Ox, sleep ON), sinhronisation few times a day, without any GPS activities or music management battery life is just around 5...6 days. Are there any possibilities to check/find reasons for such behaviour?
