19.18 - Solar edition - Battery life

This week I had to reset my watch to factory defaults because a few of bugs.

First of all, I'm always a long way from reaching Garmin's battery life limit.

As a good case, I had a trail running race 9h30 between 1600 and 3000 of altitude under 100% sun.

Activity mode with All Systems mode and wrist-based heart rate ==> Up to 34 hr. with solar from Garmin website.

The result is 50% depleted after 9h30!

Activated a course to get ClimbPro, this is the only screen in my race.

There is a gap between 19 and 34 hours!

  • Yes, i'm trying to decide which one buy between FR 955 and Suunto Vertical (mainly for hiking). Garmin is definitely more complete, but Vertical's battery is impressive.

  • In my opinion, the question is not about the watch, but about the ecosystem you choose. Both have their strengths and weaknesses, which you have to define according to your needs. Personally, I tried the Suunto Race for two months at the beginning of this year and I came back to Garmin.
