With VO2max functionality you can access vital physiological information, tailored coaching guidance, gain workout motivation and benefit from the same scientifically personalized training insights used by professional athletes. That is why the new Amazfit Stratos 3 Elite offers great functions for most athletes in the house, in addition to being one of the ones that best adapts to you both for its characteristics and for its exterior.
That wasn't true.It fared better when differentiating between forehands and backhands during play, but we often found it failed to pick up a lot of swings entirely. Now for the good news: the Stratos allows you to pair a chest strap using Bluetooth, and we tested it out on a run with the Polar H10 doing the HR work. Huami is still updating the Stratos – hopefully it will get better with time.

Granted, we were in a built-up area, but that's still longer than most. Perhaps something leather for more formal occasions, though I'm not sure I could pull this off with a suit. We did a session of serve drills and at the end it told us we'd been doing a mix of forehands and backhands in there too.
The 300 x 300 resolution is often difficult to read and fares dreadfully when lighting is poor. And yet it does all of this for just $199.

However, when we pushed up into the higher intensity bracket, the Stratos buckled, and the final average and maximum heart rates were off as a result. Once we were locked in though, we were away, and the results were consistent with our actual route and the Fenix 5S on every occasion. It's 46mm wide, chunky, and gives off the impression it could take a fair beating without much trouble. These are good metrics of overall fitness, and having them on board means the Stratos can give you a deeper analysis on your progressions, which you'll be able to pore over in the app. There's also a flat tire along the bottom, which while not as large as the ones we used to see on older Wear OS watches, is still a blemish on the overall look.

Using Spotify on the Apple Watch The third and final partnership we should mention is Strava.

Climbing and trail running will let you import GPX files (which contain lat/lon coordinates) via the computer and onto the watch, get altitude data and pair other Bluetooth sensors as well. As we said earlier, you're going to get smartphone notifications popping up here too, but this is just mirroring what comes through on your phone and you can't reply to messages or take calls from the wrist. By We'll start with running, for which we tested the Stratos against the Garmin Fenix 5S and the Polar H10 chest strap. Yeah, it's confusing. The navigation system is needlessly complicated and unintuitive, hampered by some poor translations, cut-off text and ambiguous buttons in both the watch UI and the smartphone app. Let's start with sports modes, which make up the meat of the Stratos.

While that's topping out the Amazfit range, it's significantly cheaper than, say, the Fenix 5. Apple Watch Series 5 v Series 3 So all-in-all, it's fine for when you're sweating it out on the court and want that acknowledged, but it's not going to do much to improve your game.
