Can anyone comment on how badly LiveTrack drains your watch/phone battery? I have been considering using it for my long trail runs, but ending up in the woods with both a dead watch and a dead phone make me hesitant.
A casual google search tells me it could drain it by 50% more, but doesn't indicate if that's the watch or the phone or both that experience the greater drain.
FWIW, I have a vivoactive 4s, have the pulse ox turned off/display brightness turned down some/shorter backlight timer, and use my phone for music
