Summary because I rambled a bit below: I would like suggestions for a smartwatch primarily for notifications with a good battery life and a price of less than 400 USD.

I have been using a Xiaomi Mi Band 4 for two or three years now and I'm considering upgrading to a "real" smartwatch. My primary uses for it are silent alarms and notifications, but I really need at least a 4 day battery life. My main watch when I am not wearing the Mi Band is a 38mm Timex IronMan, and I am comfortable with that size. I would like any potential smartwatch to be no larger than a 42 mm face. I would like the smartwatch and potential connected app to at least pretend not to sell my data. This is why I use the paid version of Notify for Mi Band instead of the official app (that and all of the customization). My other uses for the smartwatch are less important to me, but include step counting, activity tracking (primarily walking and biking), and sleep tracking.

I have been looking at a Garmin Instinct 2S, since it has a long battery life and apparently Garmin is "better" with data security than most. In addition, I could even use the watch without ever downloading the app, although I have yet to find out if notifications would work in that case. The 300 USD price tag is a little jarring, coming from the 35 USD Mi Band, but comparable options are just as pricey.

Honestly, the Mi Band 7 calls to me because it has improved significantly over the 4 and is supported by Notify. It would not be the "upgrade" that I had originally intended, though, and I would continue to have issues with the specialty bands for it.

Does anyone have any alternative suggestions or experiences with the above?

I am considering the purchase of a Garmin GPS watch, but I don't want to run the bloated Garmin Connect app on my phone. Really all I want, is the ability to pull coordinates from my watch (.gpx files) and put them on my phone or computer. Does a privacy-respecting app like this exist?

My husband's birthday is coming up and I want to get him a smartwatch that syncs with his Pixel. I was gifted an Apple 3 watch which I like a lot and would like to find something with the same sort of functionality for android. I tried going through watch reviews but ended up with buyers paralysis because there's so many to choose from. What would you recommend and why?

Edit: Fitness is not the key use I'm looking for.

Is there a good smartwatch/simile that monitors sleep and has excellent battery life (measured in weeks not hours)?

I use the Withings (ex-Nokia) Steel HR, but it … kinda sucks. The bluetooth pairings very often lose sleep data, it's very inaccurate, the reporting sucks for non-24s, and the leather bracelet is of very poor quality, keeps breaking.

I really don't care for the fitness/step tracking which, as someone else here put it, thinks typing on a keyboard or eating is a step.

I also briefly tried an Oura (https://ouraring.com/), but I never got it to work and had to send it back.

I also don't care much for any of those "sleep quality" trackers that try to detect if I snore and what not. I can do sleep studies in my own time, I just want to have accurate stats on whether and when I am asleep.

Hi there everyone. I gave up on smart watches after Pebble sold out to fitbit and my OG Pebble started having screen issues (again). I never watched to spend hundreds on a smart watch or switch to the iOS ecosystem to use an Apple watch.

I was wondering if anyone here has had success with any other watches after having to give up their Pebble, something with a great battery life and good notification features without resorting to terrible china-watches.

Hope you have a great day!
