Does anyone use their oxygen sensor on their wrist device? I have a garmin vivosmart 5 with an oxygen sensor but turned it off because its reading seems to wholly be related to how tight I have the band.
With the o2 sensor off my battery lasts a couple of weeks. With it on only a couple of days.
I have a good fingertip sensor for this that I bought during Covid.
I don't use it on my Garmin, because as you said it dramatically lowers battery life, and often shows up as life-threateningly low. It also doesn't do anything with the data, meaning I only see if it I go into the app and click on the Pulse Ox tile.
I leave it enabled on my Apple Watch though, the battery life is already bad and any irregularities would be shown on the vitals app.
