Re: 1 day battery?
My beloved kickstarter Pebble died earlier this year. I replaced it with a Garmin Vivoactive 3 (courtesy of Amazon 50% off). It doesn't look *too* much like a wannabe fitness tracker and I get a solid 6-7 days on the battery. Took a while to sort out notifications like I wanted (the app s/w is nowhere near as good as the pebble) but it's a suitable replacement.
