Real life battery consumption seems to be accurate for the Epix. I am going to add on a 7th activity shortly (1hr hike) and today is Day 6 since new and fully charged around mid-day last Thursday. My settings are AOD, gestures for activities but not general use and GPS set to All Satellites. Sleep settings are the schedule the watch arrived with. Shown below is battery status today, morning of day 6 and my Calander of Activities. According to the hour estimates I should have battery till maybe 4am tomorrow day 7.
