@Sebastian-Wagner-0 5h GPS means at least 10% of battery consumption. Then if you charge the watch at 10% residual battery, it means your Race consumes around 10%/day, which is slightly higher than the claimed specs, but then it depends on how many notifications your receive, how many times you interact with the watch and so on…
If you charge your watch at around 20% residual battery life, the daily battery drain goes to roughly 8.5%. And all written above still applies.
So at the end, the battery consumption could be a little bit higher than the official specs (roughly 6.5% day), but nothing too tragic IMO.
