Some data for people who wants to know how long galaxy watch can track hiking.

I did a 8 hours hike with my GW4 44mm and tracked it with SHealth. Settings: AOD Off, raise to wake on, BT on, received some notifications, No music. As you can see: in 8 hours of hiking the watch went from 98% of battery to 16%.

This a rather good result considering permanent GPS, HR and so on tracking.

GW last long enough to track a "regular" hiking. But you should better have your watch fully charged when you start.

GW5 and GW6 should have even better results.

Turing off BT and raise to wake could save some battery.

disclaimer : I posted similar post earlier on reddit (when I used it), but I think that this info can be interested for you as well.
