......... At just 24 hours you are trying to rush a charge in the AM or charging at work. That's, fine if you are an office worker but impractical otherwise. Look at Garmin and what they get?
As I said , I tend to stick it on while I'm showering and having breakfast ....This morning in half an hour or so it went from 63% to 100% , yesterday 75% to 95% so not really a "rush to charge", just a routine. If I forget it doesn't matter as it will easily last until the next morning.
As far a as practicality goes, If you NEED "days " between charge because you are no where near a power source or consider putting it on the cradle once a day "a hassle" then fair enough .
However, I would wager that a very high proportion of people who wear this sort of tech sit at a desk all day ...or at the very least in room with a mains outlet!
For my phone I have a Samsung Fast charger next to my bed and one on my desk at work and one in the car. My phone rarely goes below 50%. It has never occurred to me the S9+ will "only "last a day or so as it is always has a reasonable level of charge.
Anyway My post wasn't really about battery discharge rates more about battery longevity.
