another Garmin here – My VivoActive3 has been excellent since I first had it – very rarely take it off and it goes swimming every week along with MTBing, cross country walks, the works.
Without using the GPS it’ll last quite a while without charging (went from Xmas Eve to New Years Day before it’s next charge) and has a claimed 16hr life with GPS on.
It also has a built in default short reply function for SMS messages but not for other message notifications, e.g. email, WhatsApp, etc, all of which can be viewed on it.
Only had it since the end of October but I’d now be lost without it.
