Huami Amazfit Stratos 3 Specifications

Huami Amazfit Stratos 3 SpecificationsThe latest Amazfit Stratos multisport watch could be a market-beater for Huami/Amazfit. Certainly, the specifications look the part but only a good dose of testing prior to a review will see if the Stratos 3 can overcome the drawback of the sensor quality and interface of the promising previous model.

It certainly looks the part, just like the previous model. At first glance, there seems to be little difference but then you’ll quickly see that the 3 button controls of the previous model have been replaced by the innovative 2+2 button interface with 2 of those 4 buttons coming via a ‘rocker’ switch of some sort. That’s kinda quite ergonomically clever to have 4 buttons on one side.

Will it work? Only time will tell.

Through their initial marketing, Huami wants you to be acutely aware of the new, highly readable display (claimed) and they are also keen to point out a whopping 14 days of life in ‘Ultra’ mode – which comes out to a highly creditable 70 hours of real GPS usage. Couple that with 19 sports modes, NFC (China-only) and a good dose of Firstbeat features then I was certainly intrigued to delve some more into the details.

Next up we see there are two case versions. The basic stainless steel+silicone model is bettered by the titanium bezel and button of the Elite version which also has a sapphire screen. #Nice.

Then we come to the inevitable confusion of two operating systems each of its own chip. One for sports and one for the rest. I don’t know why they had to tell me that. I guess the argument would be that one is ‘tuned’ for sports usage.

GPS, Battery Modes & Connectivity

Huami Amazfit Stratos 3 SpecificationsThe smart mode gives a battery life of 7 days which includes 30 MINUTES of sports usage plus basic smart functionality which includes 24×7 HR. That doesn’t sound great but, actually, I think it’s fine as we then have more serious sports modes to deliver maximum accuracy over 35 hours, a balanced accuracy profile over 45 hours and a power-saving true endurance profile of 70 hours.

GNSS covers GPS, GLONASS and GALILEO (+regional). We’ll see later how accurate they might be. I also read that the now ever-present Sony GNSS chip is used, which we know CAN be quite good if integrated properly or not so good if poorly integrated.

The inclusion of WiFi looks interesting. I’m not entirely sure what it will be used for though as I would assume that workouts are sync’d over Bluetooth to the companion app and that Music will not support WiFi syncing at all. Let’s hope I’m wrong and there are direct uploads to, for example, STRAVA.

19 Sports Modes

Yep. These…

and of course, the Stratos keep the previous incarnation’s ability to play up to 1.9Gb of music stored on the watch via Bluetooth headphones

The Firstbeat features I believe are the same as on the original STRATOS and which include: VO2max Fitness Level, Training Effect: Aerobic, Training Load, Recovery Time Advisor, Real-Time Performance Condition, Personalized Training Plans: Cardio, Real-Time Coaching and Calories Burned.

  1. The second OS is for the low power CPU. Android consumes to much for a weeks long usage. A restart on Stratos (Android 5.1) can take up to four percent of battery life. WiFi is not new on the device. Pace and Stratos uses for OTA firmware upgrades. As far as I know it it possible to connect your watch to your phone via WiFi:
    https://support.amazfit.com/hc/en-us/articles/360012458813-How-do-you-connect-to-Wi-Fi-

    And of course you can install a file manager for file transfer if you don’t like USB connection:

    • 2x cpu: yes i get it. but what’s the point in having a wearOS watch when you can’t always use wearos? the amazfit site warns that there is a delay when switching the OS, i’d imagine it’s a notable delay. The WiFi *IS* on the amazfit china page – that may well mean the chip can do it but the software can’t. connecting to a phone via wifi sounds interesting

      • AmazfitOS – the GUI and the SW logic behind the watch is written for Android. If you want to use its sports functionality, AmazfitOS and Android should run. On the other hand, if you wear the watch for activity tracking and as a timepiece, the low power environment is enough (e.g. Bip family has great battery life). It is not a WearOS device, this is why using as a smartwatch is PITA (no appstore on the watch, different CPU architecture, stock Android apps are not designed to small round screen). I meant that their first generation sports watch (Pace) had WiFi. At least the firmware upgrade uses it. See this video at 4:30:

        Altough Huami has some hardware issues (battery draining, falling watch ears), the real problem is their buggy software and limited after sales support.

  2. After years of use and abuse with a Fenix 2, it died, and I gave the Stratos a shot. That watch stopped taking a charge exactly one day after the warranty expired. Not wanting to pay the huge price-tag for a newer Fenix 5plus, I opted for a VivoActive 3. THe VA3 is not without its limitations, but is perfectly functional. I even used it (with hMSport connect IQ app) during a triathlon this past weekend. Worked great.

    The point is that even the lowly VA3 felt like an upgrade over the Stratos, despite not being a premium “multisport watch”. Stratos claims 24/7HR tracking, but in reality it checked it once every few minutes. For activities, the HR monitor was a random number generator, and in no way was based on reality. It had onboard weather app that never had the right weather. It recorded activities, but could not export a usable file (although does share with Strava…. with one caveat, not indoor activities like swimming and treadmill). It supposedly runs as a layer atop WearOS, but doesn’t have access to any apps.

    I am not quite sure what the upgrade is for the Stratos 3? The Stratos 2 had excellent battery and a nice looking screen. The OS looks the same, it doesn’t include navigation or mapping, no streaming music, no indication that they’ve improved the half baked app, no information about improvements to the HR sensor, and nothing on the ability to use third party sensors like power meters.

    I am definitely interested to see some reviews, and know what is being touted as an upgrade. For the Stratos2 almost every review I could find was from folks reviewing it as a smart watch, and failed to dive into the nuances of using this for a sports training device (except here). No one mentioned that 24/7HR tracking was every few minutes, not every second like Garmin. No one mentioned it would be impossible to export or share a pool workout to Strava. That the interval workout creator was so utterly limited.

    It was a nice watch. I was very frustrated at the timing of its death, one day after the warranty ended, but it looked great and I could manage my workouts with it. I use a separate bike gps, so power meter and navigation aren’t necessarily top priority. All that said, the VA3 was about the same price as the Stratos2 (both $179 at time of purchase), and feels like such a more complete, well thought out device, with a rich ecosystem of apps that actually add new functionality! Unless folks reviewing this are being blown away, I am going to stay away. I will be closely monitoring deals for Fenix 5 plus (ebay?) after the Fenix 6 is released in a few days, and the gotta-have-it folks all migrate to something that will bebarley marginally improved (especially if there is nothing more onboard than what the 945 has).

    • I saw your ‘make cool shit’ reiteration 😉
      the sort fo things you are asking to see are fair enough but never come out until people get their hands on the watch. announcements are very limited in themselves.
      previous model: my review was the first one and it was super-detailed – https://the5krunner.com/2018/05/04/amazfit-stratos-review/ . i kinda wasted my time doing it as i didn’t get enough sales to justify more than a week i spent on it so i don’t know if i will repeat the feat, although i did like it.
      F6 is today

    • Wait for the “international version” sure this supports English out the box, I wouldn’t go as far to say I’ve been burned by Chinese with English firmware, but sometimes Chinese will show under program icons and in the menu’s, which while no show stopper is annoying.

    • Touch screen – AF coated Corning Gorilla 3 generation tempered glass (Amazfit Smart Sports Watch 3), AF + AR-coated sapphire (Amazfit Smart Sports Watch 3 Elite Edition). the touch screen can be entirely disabled for sports usage.

  3. Do you know whether it’s possible to program or record swim splits with rest intervals using the Stratos 3? Something like recording the split for 50m and then a 30sec rest intervals.

  4. Nice watch but I’m skeptic that Huami can provide a stable firmware. My old Stratos works but it crashes sometimes.. And some old bugs are still not fixed.. (intervall training, crash upon long runs, The watch must be resetted every 2 months). Huami watches are not suitable for serious Athletes. Unfortunately….
