Review of the Amazfit GTS 2: a great workout watch that won't break the bank


  • attractive, slim, and light.
  • AMOLED display with exceptional quality
  • The GPS is more accurate than on the previous model.
  • Built-in music storage for 300+ tracks
  • With the watch speaker, you can answer phone calls.


  • The SpO2 values are inconsistent, and the smartphone app is mediocre.

Huami just released the Amazfit GTR 2 and GTS 2 in the United States and Europe. The pair is a step up from the first-generation devices that were so popular. The key enhancements are a more lightweight design, a SpO2 sensor, and built-in music storage.

In my assessment of the original GTS, I discovered that it offers a lot of value for the money. It appears to be a good alternative if you’re searching for a stylish fitness watch that won’t break the bank.

Amazfit GTS 2 is available in a variety of formats. The GTS 2 Mini and GTS 2e are included in this category. These additional iterations sacrifice some functionality, but they are less expensive.

For the past few weeks, I’ve been walking about with the GTS 2 attached to my wrist. Is it a step up from its predecessor? Continue reading to find out.

design  and Features

The initials GT in the moniker stand for Grand Touring, in case you were curious. In terms of automobiles, this equates to a blend of luxury and performance. The S in GTR stands for square, whereas the R stands for round. The only variation between the two models is in the design. Let’s get to the review now that that’s out of the way.

The GTS 2 is a step forward from the original. Huami has trimmed a few millimeters off the edges, making it slimmer and lighter than before. Its exact measurements are 42.8 x 35.6 x 9.7 mm, and it weighs only 24.7 grams. You won’t even notice it on your wrist.

The wonderful 1.65-inch AMOLED display is still present and accounted for. The resolution remains the same (34442), but the screen now has a brightness of 450 nits and a diamond coating to prevent scratching. This makes it a bit more durable and an improvement over its predecessor’s Gorilla Glass 3 protection.

This is marketed as a bezel-less screen by Huami. That isn’t entirely accurate, as the display has dark margins surrounding it. They are, however, quite little.

I was blown away by how clear the screen was and how vibrant the colors were. The quality is comparable to that of the Apple Watch and other even more expensive gadgets. Everything is plainly legible, whether inside or out. The display brightness may be customized in the settings, but I went with the automated mode in the end. In bright sunlight, I occasionally increased the brightness to its maximum setting.

Having said that, the screen did go significantly dark at one point over the weeks of testing. I wasn’t sure if I was the source of the problem because I was rummaging through the various options. I couldn’t figure out how to fix it, but a simple restart brought everything back to normal.

There’s also the option of having the display stay on all the time. When the screen is lit, it alternates between showing the time and your complete stats. Just keep in mind that this will deplete your battery life..

Despite having mostly comparable design specifications, the GTS 2 and its predecessor are easy to distinguish. Take a look at the right-hand single physical button. It is larger and better integrated into the main body in the second generation. The watch has a curved shape with no sharp corners.

In terms of construction, we’re getting an aluminum alloy and a polymer substance once again. A silicone strap completes the look. Of course, the aluminum alloy case comes in a variety of colors, including midnight black, desert gold, and urban gray. As you can see from the photos, I put the midnight black option to the test.

The watch is compatible with a variety of Amazfit and third-party bands. Detaching a strap from the clock takes only three seconds thanks to the pin system.

You can dress things up even more with a variety of watch faces. A lengthy tap on the screen brings up a total of nine options, all of which may be found on the device. You can’t upload your own watch faces, but you may swap out the ones you have for a variety of others on the smartphone app.

The GTS 2 features a 5 ATM water-resistance certification, as before. As a result, it’s ideal for swimming and other aquatic and underwater activities. Excellent water resistance has become the standard, unlike a few years ago. We hardly ever consider it.

Thanks to an improved BioTracker PPG, you now have blood oxygen monitoring as well as sleep apnea monitoring. These features aren’t present in the original. A 9-axis accelerometer has also been installed in place of the 6-axis one.

Built-in storage for music is one of the other enhancements. GTR 2 has a gigantic 3GB of storage for this reason, which may hold anything from 300 to 600 songs. The smartphone app makes it simple to transfer music, but more on that later.

Which is better: the Fitbit Ionic or the Garmin Vivoactive 3?

The GPS/GLONASS system is still operational. Fortunately, it performs better than its predecessor. The time it takes to establish a connection has decreased, and the satellite signal’s precision has improved. However, it can still be a little patchy. It works perfectly some of the time, but it may be somewhat off at other times (for example, in densely populated regions).

When it came to obtaining the signal, the first time I went out, I was unable to do so. However, this is due to the fact that I had not updated the GPS settings file. As a result, make sure you update the GPS file on your watch because it will perform a lot better.

When you sync the watch with the smartphone app, this is done. It didn’t take long to get a satellite signal when the files were updated. The Garmin on my other wrist took around 10-15 seconds longer.

The battery life is the last item on the list of specifications. The original’s 220 mAh battery has been replaced with a 246 mAh battery. However, despite the improved specifications, the actual battery life has remained unchanged. Huami claims a battery life of up to 7 days in standard use mode and 20 days in basic use mode. With GPS turned on, this time drops to 25 hours.

In practice, I discovered that I only needed to charge my phone every 4–5 days. But I was pushing the watch to its limits, allowing all the battery-draining features and running with GPS on every couple of days. The good news is that it just takes 30-60 minutes to charge.

Nonetheless, I wish Huami had extended the battery life a little longer. I would have been a lot happier if I had had another ten days. Even if it meant adding bulk to the device’s construction to accommodate a larger battery, I would have preferred this. A week, on the other hand, is about average-you don’t get much more on a Fitbit, and Apple’s watch is nowhere near this level.

Review of the Amazfit GTS 2: Features

Track your fitness and health

When it comes to fitness and health tracking, the majority of the new Amazfit watches have comparable features. This covers standard metrics like steps, distance, calories, and sleep, as well as blood oxygen and stress monitoring. The majority of the statistics are available on a daily, weekly, monthly, and annual basis. The only thing lacking is a count of how many levels you’ve climbed.

It’s tough to compare the watch to other devices in terms of step count, distance, calorie monitoring, and sleep data quality. Having said that, I did notice that the step count was consistently low. However, each brand has its own unique algorithms, so the statistics will never be identical. In my opinion, you can compare like with like if you wear the same equipment every day. As long as the figures are roughly true, that is.

Huami’s unique operating system, which I like, is used on the watch. Everything is well-organized, the menus are simple to explore, and the watch responds well to touch. There isn’t much of a learning curve, and there’s no need to read instructions. It’s all quite self-explanatory.

Unfortunately, the Zepp smartphone app does not share this sentiment. This is the app you’ll need to download to your smartphone. It’s not bad, but it might be better because figuring out where everything is tucked away takes some time.

Many, but not all, of the most important statistics are available on the dashboard. Tap on the four-leaf clover in the top right-hand corner of the screen to see a list of everything that’s accessible. This brings up a box that says “All data.” Then you can choose what you’re interested in. All of this, in my opinion, should have been made much easier.

Review of the Amazfit GTS 2: A great workout watch that won’t break the bank.

The observations and explanations were really appealing to me. They’re usually below the data, so they’re not in the way if you don’t want to read them.

The sleep statistics are pretty comprehensive. You’ll get a summary of your sleep patterns, including deep, light, REM, and awake time, as well as an overall sleep score. There are also some additional “abnormal” statistics, such as the quality of one’s sleep breathing. This places you on a scale of 0 to 100 and is labeled “Beta” (work in progress).

Unlike many other watches, the GTS 2 recognises naps of more than 20 minutes. This is critical for someone like me, who likes to complement my short nightly sleep bouts with a long afternoon nap. It will even attempt to segment your slumber into distinct stages of sleep.

A stress score is one of the more fascinating statistics. This works nicely and can be set up to run on demand or automatically throughout the day.

However, I found the SpO2 readings to be a little erratic. The sensor would work great some of the time, but the results would be blatantly inaccurate at other times (below 85 percent). Perhaps a tighter fit for the watch against my skin would have fixed the problem, but I’m not sure I trust the SpO2 sensor.

You’ll also receive a PAI score to ensure that your heart continues to beat regularly. For those who aren’t aware, these types of metrics are becoming increasingly popular. Steps were all the rage a few years ago, but they aren’t the best way to keep track of your activity. Riding a bike, for example, will not increase your step count after a one-hour ride around the park!

Instead, PAI considers how hard your heart is working, as well as exercise time and other complicated health data. The PAI Index is supposed to be kept above 100. All of this is backed up by science. In fact, it is backed up by one of the most comprehensive health studies ever undertaken.

Tracking sports

There are numerous sports modes available, and Huami has stated that it will continue to develop new ones. Some of these have GPS/GLONASS for phone-free training. Outdoor jogging, treadmill, walking, outdoor cycling, pool swimming, and elliptical are all recognised by the auto-recognition mode.

As previously said, I found GPS tracking to be superior to its predecessor. It was easy to get a signal when I updated the GPS files on the watch. The end product isn’t quite up to par with a high-end sports watch, but it’ll do for most people.

On a few occasions, I ran with GTS 2 and a Garmin strapped to my other wrist.On my most recent 3K run, here’s how they stacked up.

As may be seen from the picture, the distance between the two was about 30 meters over 3 kilometers. In terms of heart rate, GTS 2 kept me at an average of 164 beats per minute and a maximum of 183 beats per minute. On the Garmin Forerunner 935 (with a Polar OH1 heart rate chest strap), the results were 159 and 173 beats per minute, respectively.

The previous run had been even better. Although my heart rate was higher on the GTS, the GPS figures matched precisely. The average and maximum heart rates were 158 and 170 beats per minute, respectively, compared to 155 and 165 beats per minute on the Garmin.

I’ve noticed that the variances in GPS readings are greater in densely populated places. Large structures will interfere with the transmission, so this isn’t surprising. However, I believe Huami is making progress in improving GPS accuracy on its devices. It’s not quite sports watch quality yet, but it’s on the right track.

The heart rate monitor is in the same boat. The enhanced BioTracker PPG sensor, according to the business, enables abnormal heart rate warnings. Fortunately, despite turning this option on, I did not receive any such notifications.

Features that are clever

Then there’s clever functionality. The GTS 2 can display SMS and app notifications, as well as incoming email alerts, just like the rest of the Amazfit watches.

App alerts, on the other hand, can be adjusted through the smartphone app. Zepp, WhatsApp, Viber, Skype, Facebook, Instagram, Twitter, Youtube, and Calendar can all be enabled or disabled individually.

Review of the Amazfit GTS 2: The latest generation includes some useful additions.

A speaker and microphone are incorporated into the watch. This means that you can accept calls as well as receive call notifications on it. Because this feature is disabled by default, you will need to enable it. The settings will guide you through a different pairing process that is required for this to work.

It entails ensuring that your phone is discoverable via Bluetooth and connecting to it through the watch’s settings. You’ll need to type in a code on both your phone and watch to confirm the pairing.

You can use the offline voice control on your watch to perform voice commands even if you don’t have internet access. The Zepp app settings page allows you to change this. Personally, I don’t think that’s really useful and consider it more of a gimmick, but it’s nice to have the option.

Aside from that, the clock, alarm, stopwatch, weather, and camera shutter functions are all standard. The watch features NFC for contactless payments in the Chinese version, but it was not carried over to the international version.

Storage for music

The 3GB of on-board memory for storing your own music is a major selling factor for the GTS 2. That’s enough material for almost 300 songs. Actual MP3 files from your library will be required.

There is, however, a learning curve. It took me nearly half an hour the first time I tried to upload a song to figure out how to do it. It would have been a lot simpler if Huami had given us clear directions. I was on the verge of giving up! It’s now second nature to me, but only because I went through the learning process.

The smartphone app is used to upload music to your watch. Although there are alternative options, this is the simplest.

Hopefully, this will save you some time.

Select your watch from the smartphone app’s profile page. Select the music icon from the drop-down menu. This will send you to a screen that simply reads, “Upload music.” When you click that, you’ll be taken to your standard file browser. Choose the MP3 file you wish to upload now. So far, everything has gone well.

What I was stuck on was deciding what to do next! The following is what has to be done.

As illustrated in the screenshot above, select the “Uploading” tab. You’ll see a screen telling you that you need to connect your smartphone to the newly built GTS 2 hotspot. Disconnecting from your WiFi or cellular service is done through your phone’s settings. Once you’ve finished, the upload of the file(s) will begin automatically.

It took me around 2-3 tries before the hotspot truly worked for me. However, once it did, the transfer was relatively swift.

The watch’s music controls are well-designed. You can listen to playlists or individual songs and play, pause, and skip through them. When exercising, you should use Bluetooth headphones to connect to the watch.

The watch speaker’s quality amazed me greatly. Without headphones, you can listen to the music fairly well at the highest volume setting. You probably won’t be able to perform it while jogging, but you can do it while walking and definitely indoors.

The watch may also be used to control music on your smartphone. This is a feature that may be found on a variety of other Amazfit watches.

The Alexa control is also worth mentioning. This is an advertised feature that has yet to be implemented in the watch. According to Huami, it will be an OTA (over-the-air) upgrade. I tested this feature on the Amazfit Band 5 and found it to be quite useful.

On the Band 5, you can get to the service by swiping right from the device’s main screen. The message “I’m listening” can be found there. After that, it’s simply a matter of asking questions. Huami stated earlier this year that the capability would be available in Q4 2020, so it should be available shortly.

The verdict on the Amazfit GTS 2

The Amazfit GTS 2 is a significant upgrade over the original. It has all of the same features as the original, plus music storage, a SpO2 sensor, a lighter design, and a few extras. According to Huami, Alexa capabilities will be available as a software update in the near future.

Overall, the GTS 2 has a good collection of features for the money. The show is really amazing. It’s bright and clear, and it responds to touch quite well.

For running, I found that the GPS and heart rate performed nicely. However, I would consider this a fitness watch rather than something I would recommend to serious runners. They’d be better off with a full-featured sports timepiece. For the rest of us, the GTS 2 will suffice admirably.

Which is better: the Fitbit Ionic or the Garmin Vivoactive 3?

The watch costs roughly $30 more than its predecessor, at $180 on Amazfit’s website. However, Amazfit does occasionally provide substantial savings. It’s also available on Amazon and Argos.

If you prefer a circular design, the GTR 2 has nearly identical specifications. The GTS 2 Mini is yet another possibility. It has a smaller body and no music storage, yet it only costs roughly $99.
