The distance of the hike was rather long — 22km. Since I wasn’t the “trail keeper,” I decided to passively track my hike using my Galaxy Watch 4, without starting any active navigation apps like Komoot (article about my experiments with Komoot in Alps).
I charged my watch during my drive to the starting point. Therefore, I began my hike with 98% battery. I deactivated the always-on display (AOD) — the only setting adjustment I made to increase battery life. To further increase battery life, one can also disable Bluetooth, turn off raise to wake, disable activities autodetection, and reduce screen brightness. I didn’t do any of these. Side note: I received and checked several notifications on the watch during my hike. Afterward, I started the “hike” exercise on my watch and began hiking.
