I definitely agree that there is a problem with the Bluetooth on the watches (especially the Vertical 1, in my case). I changed the battery in my Suunto belt a month ago, and it’s already at 50% battery life. That’s completely abnormal.
However, in my case, the reduced battery life only affects the Vertical 1: the Race 2 has excellent battery life. Furthermore, another indication that there is an issue with the Vertical 1 is that at night it consumes 3-4% of its battery, compared to the Race 2, which consumes 1%, with the same settings.
