When I'm navigating and the TBT screen is getting a workout, the 6-7% per hr so I'm thinking it'll navigate a long day. So yes, I can see where some higher level thinking on the part of the device uses more battery. Saw this with the 1000 as well as the 810 as well.
I did a 26 hour hike/climb this weekend. I use a Garmin watch to record my tracks. Normally it drains about 5-6% per hour. Towards the end it seemed to be in the ballpark of 30% per hour.
I've seen this before, usually less pronounced. It wasn't caused by nav or anything like that, or even use of the backlight. My hunch is that managing a large data set drains the battery too.
