The Amazfit Stratos Multisport Smartwatch Review provides a comprehensive analysis of all the major features and functionalities.

Amazfit Stratos is a watch that lies just between a sports watch and a smartwatch. You could say that Stratos is primarily about fitness.

It can track a wide range of sports and activities, including walking, running, swimming, cycling, triathlon, elliptical, mountaineering, trail running, tennis, soccer and skiing. It holds a reliable built-in GPS and GLONASS (Russian satellites which should offer a faster lock-on).

On top of that, it has a heart rate monitor and an outstanding battery life that easily outperforms some of the best wearables.

All these, at only $179.99. A sports watch offering these features costs at least 0 more. So, it is cheaper than most of its competitors.

Overall, the Stratos is a relatively complete multisport watch, delivering a wide range of functionalities, supplied with a variety of sensors. It offers many functions at a challenging price for a watch of this type. A high end watch at a low price.

Let’s break it down.

The Amazfit Stratos is an elegant, good looking watch but a bit chunky. The carbon fiber case along with the polished ceramic bezel, usually found in premium smartwatches, stand out. The big display size of 1,34’’ is protected by the 2.5D Corning Gorilla glass.

It has an always-on LCD color touchscreen display 320 x 300 pixel, a 1.2GHz processor and 4 gigs of storage.

The 1.34″ display is transflective. This is great in sunny conditions. At night or when it gets dark there is a backlight function that automatically turns on when you flip your wrist around.

You can adjust the brightness level of the display. Dimming the display extends the battery life significantly.

The Amazfit Stratos has a high resolution of 320×300 pixels, resulting in crisp, easy to read the text.

On the right side of the watch, there are three stainless steel physical buttons for navigating through the User Interface. The watch comes with a universal 22mm silicone rubber strap easily replaced by using quick release pins.

Despite its size, Stratos weighs only 60 grams.

The Stratos is water-resistant to 50 meters and can track both pool and open water swimming.

The heart rate monitor is centered on the back with four connection pins in a row for the charger above the heart rate sensor. In order to charge, the clock snaps to the dock charger that is powered via USB-A.

User Interface

The Amazfit Stratos is a feature-rich smartwatch with a rich user interface. In terms of usage it combines touch-screen functionality with physical buttons.

The buttons can be either long or short pressed to do different things. In case of an activity, the screen can be locked to prevent accidental gestures.

The watch connects to mobile phone via the Amazfit Watch app. You can use the app to change or customize the Watch Face or directly within the watch itself. There are 14 built in watch faces that are really useful and stylish. However, you can download thousands from Amazfit’s site

Swiping left or right you shift between the different widgets of the main menu of the device. These include:

  • Step Count and Activity
  • Past Activity Summary
  • Heart Rate
  • Music
  • Alarm
  • Weather
  • Compass
  • Training

The menu is very responsive and the watch is reactive to gestures.

Fitness metrics

The watch offers a plethora of sports activities and comes with built-in GPS and GLONASS support.

It is worth mentioning that Amazfit has teamed up with FirstBeat, who performs Garmin’s advanced metrics. This brings VO2 Max to the watch, along with Training Load and recommended recovery time.

These are significant fitness metrics, providing a more comprehensive and well-documented analysis on your daily progress. Such metrics are features usually found in high-end sports watches.

GPS Navigation – Accuracy

The GPS tracking sensor is very responsive and precise. It appears to be quite accurate even in heavily wooded trail conditions.

The Amazfit Stratos, in several test runs, matched closely the distance recorded by Garmin Fenix 5 Plus. The Elevation recorded was also very precise coming very closely with the Garmin device.

It seems that Stratos does a great job in tracking running activity.

In addition, Stratos records the GPS track and allows navigation along a pre-recorded route. If you exit the pre-defined route, vibration alerts will inform you accordingly.

Optical Heart Rate Accuracy

The optical heart rate data performs quite well when comparing it to Fenix 5 Plus. In case of a moderate run, heart rate is generally reliable. However, when it comes to higher intensity training, the measurements are not that trustworthy. The optical sensor does not perform accurately in high-intensity training.

In short, if you are serious about getting accurate heart rate monitoring, I would suggest using a separate chest strap monitor that could pair to the watch.


Battery life

Amazfit has put a 280 mAh Li-Po battery into the watch. It advertises that battery will get you around 35 hours in GPS mode, 5 days in regular mode and up to 11 days in basic mode.

Of course, it depends a lot of how you’re using the watch. For example, if you turn on continuous heart rate monitor and streaming music via Bluetooth you’ll drain your battery quickly. On the other hand, if you use it as a watch, or even better if you set it to flight mode, you’re looking at least 10 days of battery life.

You can charge the Stratos via a charging dock that simply plugs into a wall socket via USB. You need around 1.5 hours to fully charge it while a glass being filled up is animated on the display.

Customized training programming

It is good to know that this function is only available for running! The Stratos offers training programs for beginners and advanced runners. One can program a training to run a 5 km, a 10 km, a half-marathon or a marathon. For example, the watch will offer an 8-week program including interval training, recovery sessions, etc. It can even offer sessions based on previous ones, for example propose a recovery session after 3 active sessions performed the previous days.

An audio coaching (usable with Bluetooth headsets) guides the sportsman in the race (pace to adapt to remain in the fixed objectives)

It is also possible to set objectives to reach (duration, distance to arrival, calories to burn, Training Effect for example) or even program alerts based on the pulse value, pace, etc.. For example, the watch vibrates when working outside the set objectives.

The watch allows you to schedule interval training sessions. However, the programmable time is in minutes, which makes it difficult to schedule short interval sessions.

On-board Music

The Amazfit Stratos features 4 GB of onboard storage. Of these 2 GB can be dedicated to music. Approximately 250 songs. The supported music file formats are MP3 and M4A. You can easily add music via USB cable or upload it from the Amazfit Watch app from your mobile.

You can store the music on the device as a simple MP3 player. The device does not support streaming services. Bluetooth headphones are paired easily and effortlessly.

Physiological measurements

The watch’s sensors calculate a set of physiological measurements offered by some of the top range of sports watches. The drawback is that the data calculated are based on the heart rate, which is measured by the optical frequency sensor, which is not very reliable. Therefore, a chest belt is suggested, if you want reliable data.

The Amazfit Stratos measures:

  • The VO2max estimation. This is a great performance indicator.
  • Training Effect (from 1 to 5). An indication of the workout effect.
  • Recovery time after each training session
  • Estimation of burnt calories
  • Training load estimation. It measures whether the total volume of training performed over the last 7 was optimal or not
  • Performance conditions: Compare performance in real-time to past performance.
  • However, the Amazfit Stratos is not addressed only to athletes. It can also attract non-athletes as an activity tracker that counts steps, calories burned, floors climbed and analyzes sleep.


Smartwatch Application

The watch displays calls, SMS, MMS and email notifications. It is easily connected with the mobile via Bluetooth using the free Amazfit Smartwatch app. The software offers a graphical interface using and displaying the recorded data like training, performance or course.



The Amazfit Stratos is an impressively feature-rich smartwatch focused mainly on the fitness side of things.

It packs in just about every sought-after fitness feature for a great price tag.

The Amazfit Stratos is an affordable GPS sports watch, that goes head to head with the top of the range sports watches like Garmin or Suunto.

If you are looking for a feature-packed budget fitness watch, the Amazfit Stratos is the best option.
