@Horizontal_2 I am now on my third Suunto, 9 Baro which I kept for 4 years, V1 which was 2 plus years old. I noticed no difference in battery consumption on either watch.
On the V2 I am getting about 9 days with 10-12 hours GPS a week and about 6 non GPS.
Watch is on AOD but needing a button press to make the screen active.
24h heart rate is off. Sleep tracking is off. Notification are on. Brightness levels are low.
In GPS mode I’m very impressed with V2.
For reference with the V1 I’d get about 2 weeks with similar GPS.
