Battery Save Mode Effectiveness

Hey everyone, I'm heading out on a multi-day bikepacking trip in just over a week and I'm wondering if anyone has run their K2 exclusively in battery save mode for longer rides. I'm trying to grasp how much battery life I'll actually save with the display being off most of the time. I do plan on running navigation and connecting to an HR and speed sensor, so I'm sure that will affect battery life. Any insight is appreciated!

  I use the battery save mode on my K2 for most rides, not because I need to but because I prefer to only have my computer screen on when I need it for an upcoming turn, a Radar alert or a phone notification. Most of my routes have a lot of turns, so my K2 does wake up quite often. I also have it paired to an external Bluetooth speaker for audio navigation instructions and alerts. Using it that way, my K2 uses about 6% per hour with the screen brightness set to 50%.

  On your bike packing trip, you will probably want to charge your K2 overnight.

  Thank Johnny. I currently use about 10-11% per hour with 70% brightness and display always on. I was hoping that battery save mode would reduce burn to maybe 3-4% per hour. I plan on taking an external battery pack to charge at night!

  I did a 152 mile partial gravel ride last month, total ride time 9:16, elapsed time 11:14. Run route and HR, Screen fully down and still had 50% left when I got home.

  Should be good for about 22hrs.

  I would echo what Derbyshire Pantani has said, done a few 11hr+ elapsed time days with 2 sensors, map with sounds and also using a SIM card no problem at all. 

  If you need the device for navigation the screen wakes up on turning points which makes it nice and easy to use.
