so, what is more important to you, battery life or the data that AW provides?
Yes, Garmin fanboys glamour about the 2 week or whatever battery life, but some users have posted here multiple times that if you turn on all notifications and such on a Garmin, make it more "equal" to the AW "updates" (like you say happen every second), then battery life is no or only marginally better to the AW. But this is anecdotal and I have personally no data to back this up, just from posts here.
There are lots of settings to disable features on the AW, me, why would I turn these off? they are what makes the AW the dominant smartwatch after all. And you can customize your notifications and turn them all off, but you know that.
There are 3 features that come to mind, detection of irregular heart beat, fall detection and then the integration that unlocks my Macs (I bought the base Neo without TouchID), and lastly ApplePay that I would not want to live without anymore, and those are typically not mentioned as "needed" features ...
I've has an AW since 2015, charging has never bothered me on a daily basis and quite frankly I do not understand why people happily charge their iPhones every day but yet take issue with the AW.
Have you ever used your AW in "low power mode" for an extended period of time to see what battery life will result out of it?
