@Łukasz-Szmigiel That’s good to hear that the in-activity battery life has kept up over the years. How is the day-to-day battery on your watch? Mine took a bit of a dive after the last update it received. I lose 8-10% daily, excluding activities, with HR off.
It’s interesting that Suunto still lists the 9PP’s battery life as 30 days (time mode) and 21 days (w/ tracking and HR). This was only ever possible at the time of release when the wrist HR activated once every 10 minutes. Even with constant HR, I feel like there was a period where I could get two weeks out of the watch. With the current (and final?) software, I’m down to 5-7 days with HR off.
