Just continue to charge your Garmin when you take a shower. I don’t understand why you need to change your habits. Are you worried about making the battery full at longer durations causing degradation? A smartwatch is fundamentally a disposable piece of electronics that last a few years.

The garmin has so much battery life that when it's at 10% and starts complaining that the battery is close to dying I still have about 2 days to remember to charge it.

And obviously you don't get penalised for charging it more often. Just charge it every Sunday if routine is a big issue.

I had the exact same experience. Charging an Apple Watch is a routine thing, charging a garmin is an infrequent annoyance.

And like the other commenter says, I could just fix my habits. But no, that’s not how my brain works

I am currently using both an apple watch SE 2 and a garmin vivoactive 5 simultaneously. Even if the Garmin has better battery life, I don't really like it for 2 reasons: - the round watch UI is ugly and doesn't work with the other UI elements. Also I don't mind using a squared watch, I like it. My Casio is also square-ish. - the UX is terrible, the customization is terrible. The default watch faces are all quite ugly, and the Garmin app makes the customization experience even worse.

Also, I feel like the sleep is more accurate on the Apple watch than on the Garmin from a couple episodes that happened and in general from the differences in tracking time.

Also, as you already said, I just charge the watch everyday while I shower, so battery life is not really an issue for 80% of the time. For the other 20% it's really annoying... but I think a newer model (and I hope that the new ones will be even better on that side) will have better battery life. When the battery life will be ~48 hours it will be perfect for me.
