Huangươi launched two smartwatches under Amazfit"s GT series last year - GTR 2 & GTS 2. We already reviewed the GTR 2 and were impressed with its kiến thiết, OLED screen, smooth UI, và battery life that"s longer than any smartwatch with a real OS.

Today we have sầu the GTS 2 with us, which is largely identical to the GTR 2 in terms of internals, but comes with a different kiến thiết. So which one should you get? I used the Amazfit GTS 2 for a few weeks to lớn find that out.
Amazfit GTS 2 specificationsDisplay: 1.65", 348x442 pixel AMOLED color screen, 341 ppi px mật độ trùng lặp từ khóa, 3D Glass Straps: Detachable silicone straps, 20milimet width Operating System: RTOS Features: Real-time heart rate monitor, Blood oxygen level measurement, Stress Monitor, 5ATM water resistance, Sleep Tracking, Sports Tracking, Step Counter, call & App Notification alerts, Standing Reminder, Phone Finder, Weather Forecast, Music Control, Offline Voice Control, Calling Sports Modes: More than 90 sports modes, including Walking, Outdoor Cycling, Yoga, and Pool Swimming Sensors: BioTracker 2 PPG Biological Optical Sensor, SpO2 Sensor, Accelerometer, Gyroscope, Air Pressure Sensor, Ambient Light Sensor Connectivity: công nghệ Bluetooth không dây 5.0, WLAN 2.4GHz, Compatible with Android 5.0+ and iOS 10.0+ Positioning: GPS + GLONASS Misc: Linear Motor, Microphone, Speaker Battery: 246mAh Battery Life (advertised): 7 days Colors: Midnight Black, Desert Gold, and Urban Grey Dimensions: 42.8 x 35.6 x 9.7 mm Weight: 24.7 grams
At 24.7 grams, the Amazfit GTS 2 is very lightweight & comfortable to lớn wear during a workout & at night. Its main module is made of aluminum alloy, and the screen is covered with 3 chiều glass, which blends in nicely with the sides, offering a seamless scrolling experience. The 20milimet detachable silicone straps of the GTS 2 are smooth, and I don"t have any complaints about them.
On the left side of the GTS 2 is the speaker, & on the right is a physical button. It offers decent feedbaông xã & is used to lớn unlochồng the smartwatch, return lớn a previous menu, & wake the screen. And like a few other Amazfit smartwatches, it"s also the only way on the GTS 2 lớn access all the features. Although you can customize its double-press gesture to lớn quickly launch an tiện ích. By default, it opens the Workout ứng dụng.
The glossy back panel of the Amazfit GTS 2 is made of plastic & is trang chủ to charging connectors, an SpO2 sensor, và a BioTracker 2 PPG Biological Optical Sensor. These are placed on an elevated plate, which helps prsự kiện the accumulation of grime over time & ensures proper tương tác with the skin for accurate measurements.
The Amazfit GTS 2 also comes with 5ATM water resistance, meaning you don"t have to take it off your wrist when going for a swyên or a shower. However, I don"t like the overall design of the GTS 2. The smartwatch looks elegant and has a small footprint which may appeal to lớn people with smaller wrists, but it feels delicate, and a few people even asked me if it"s a kids’/women’s smartwatch. And if that"s something you want lớn avoid, you are better off looking elsewhere.
The Amazfit GTS 2 sports a 1.65" Always-On AMOLED display of 348x442-pixel resolution, which comes with the protection of the so called diamond-lượt thích carbon coating (oDLC), making it scratch và wear-resistant.
The panel"s quite vibrant, and at 100% brightness, I was able to see the on-screen content under svào sunlight without much hassle. It"s not the brighdemo around, but it gets the job done.
The display has a nice touch response and supports over 60 watch faces through the Zepp ứng dụng at the time of writing this review, which are grouped in six categories - Artistic và Creative sầu, Exercise và Health, Traditional và Classic, Digital Dashboard, Multiple Features, and Fashion Pioneer. I like most of them, but if you don"t like what"s on offer, you have the option lớn create your own watch face by uploading a pholớn from the paired smartphone through the Zepp phầm mềm.
That said, some of the available watch faces are customizable, allowing you to select what information you want to see on the watch face. Moreover, most watch faces tư vấn a matching Always-On Display (AOD), meaning the watch face on the homescreen và on AOD look similar.
The Always-On Display can also be turned on/off automatically at a given time daily. The timing can be customized from the Zepp phầm mềm as well as the GTS 2. You also get three watch face styles for AOD - Follow Watch Face, Digital Watch Face, và Pointer Watch Face.
The Amazfit GTS 2 is compatible with Android & iOS devices, & you need to tải về the Zepp ứng dụng on your điện thoại thông minh to phối up the smartwatch, sync data, and tinker with its settings.
The Zepp phầm mềm was called Amazfit until last year, but not much has changed on the inside even after the rebranding. The phầm mềm continues to lớn have sầu shortcuts for some settings at multiple locations, & the ones not supported by the wearable are grayed out instead of being hidden.
It"s been several months since the rebranding, and Amazfit should"ve tweaked the app"s design by now khổng lồ offer a better user experience, but the fact that they haven’t yet could send a wrong message khổng lồ their current và potential customers.
However, the custom OS running on the GTS 2 is responsive, has a simple UI, and it works the same way as on GTR 2: a swipe up on the homescreen brings up the Notification Center, và a swipe down gives you quichồng access to a few settings while also showing the battery percentage, weather, và connection status. These settings span across a couple of pages that you can scroll horizontally, and it would"ve sầu been nice khổng lồ allow users to customize these shortcuts in a way similar lớn what we see on Android devices. But I think that"s a bit too much lớn expect from an RTOS-running smartwatch.
That said, a left swipe on the homescreen lets you access PAI, Activity Goal, Heart Rate, Weather, and Music Control pages. You can customize these Quiông xã Access Apps và rearrange their order by heading to the Settings > User preferences > Quichồng access tiện ích menu on the GTS 2.
Swiping right presents Shortcut Cards, including Music Control, Alarm, Weather, PAI, Heart Rate, Activity Goal, and SpO2 by default. You can change this lớn your liking by navigating khổng lồ the Profile tab > Amazfit GTS 2 > Shortcut Cards thực đơn in the Zepp phầm mềm.
To access all the features và settings & start a workout, you have khổng lồ rely on the physical button, which can also be used to go directly khổng lồ the homescreen if you don"t want lớn hop through multiple right swipes in the UI lớn go bachồng to lớn a previous screen.
Making the phầm mềm danh mục accessible only through a button press is wasteful and leads to lớn a not-so-pleasant experience. Amazfit could"ve sầu done away with the Quiông xã Access Apps or Shortcut Cards since both serve sầu a similar purpose và would"ve sầu instead allotted a left/right swipe gesture for the app menu.
Features & Performance
The GTS 2 is one of the most feature-rich smartwatches from Amazfit. It comes with real-time heart rate monitoring, blood oxygen màn chơi measurement, sleep tracking, stress monitoring, sedentary reminder, and 90+ sports modes.
Additionally, the GTS 2 comes with music control, weather forecast, phone finder, barometer, compass, GPS, stopwatch, countdown timer, screen lock, và ứng dụng notifications. Besides, you get 3GB of internal storage và music control, but oddly enough, there"s no camera control - something we"ve seen even on budget wearables.
The GTS 2 has a microphone & a speaker as well onboard, which allows you lớn answer phone calls when connected khổng lồ the điện thoại thông minh through Công nghệ Bluetooth. You can also operate the wearable through voice commands.
For heart rate monitoring, the Amazfit GTS 2 uses a BioTracker 2 PPG Biological Optical Sensor, which can measure your pulse automatically at an interval of 1 minute, 5 minutes, 10 minutes, & 30 minutes. The heart rate can also be measured manually from the smartwatch whenever you want, which on average took 15-20 seconds in my testing. You get an overview of your daily heart rate data in a graphical size on the GTS 2, but you need the Zepp app for a detailed analysis.
However, it"s worth mentioning that the GTS 2 recorded inaccurate pulse at times during the workout, so it"s best to not use the heart rate data from sports modes as a basis for diagnosis & treatment. But when I compared the manual measurement"s values with the T-Rex Pro"s, they were mostly the same.
Another problem I had was with the SpO2 sensor on my unit, which refused to work most of the time & didn"t measure the blood oxyren cấp độ. This could be specific lớn my unit, so if the sensor works normally on your smartwatch, you"ll find all the data about your blood oxygen saturation on the Zepp ứng dụng.
Next up, we have sầu sleep tracking, which is accurate. Well, at least the fall asleep, wake up, & awake times were recorded accurately by the GTS 2, but we can"t say the same for the Light Sleep, Deep Sleep, and REM Sleep since we had no way lớn determine the accuracy of those numbers.
That said, the Amazfit GTS 2 also records afternoon naps and monitors your sleep breathing unique. However, it doesn"t give sầu you a glimpse of your last night"s sleep like the Stratos 3 does, so you have sầu to lớn rely on the Zepp phầm mềm lớn check the total number of hours you slept while also taking a look at the other data.
The GTS 2 can also measure your bức xúc levels. It"s done automatically every five minutes, & the daily bao tay data is accessible on the smartwatch, with the detailed information provided in the Zepp ứng dụng.
Like I already said, the Amazfit GTS 2 supports over 90 sports modes, which are grouped into 12 categories - Running và Walking, Cycling, Swimming, Outdoor Sports, Indoor Sports, Dance, Combat Sports, Ball Sports, Water Sports, Winter Sports, Leisure Sports, và Others.
Some of the outdoor sports, including Open Water Swimming, tư vấn GPS route tracking, but due to lớn the COVID-19 situation in India, I couldn"t kiểm tra the accuracy of the smartwatch"s built-in GPS, which eliminates the need to lớn carry a điện thoại thông minh khổng lồ trachồng your workout route. It"s also worth mentioning that you can control music with a left swipe on the screen during a workout, và navigate the GTS 2"s UI, and kiểm tra notifications, which is appreciated.
You can head khổng lồ the Activities section on the GTS 2 to lớn access all the exercise data collected by sports modes, which is better presented in the Exercise record section in the Zepp tiện ích.
In addition khổng lồ the Sports Modes, the GTS 2 also features an automatic step counter. It isn"t entirely accurate lượt thích many other smartwatches và fitness bands, but you still get a fair idea of how much you walked. Like some other health data, you can check your daily step count on the GTS 2 & head khổng lồ the Zepp tiện ích for your daily, weekly, monthly, & yearly performance.
The last health and fitness feature in the danh sách is the sedentary reminder, also called Standing Reminder, which triggers a vibration reminder if no activity is detected in the first 50 minutes of an hour when you are wearing the watch.
As has been the case with most Amazfit smartwatches for a while now, the notification management on the GTS 2 isn"t perfect và needs improvements because the smartwatch doesn"t let you delete the notifications when they first pop up on the screen. You also can"t delete them individually from the Notification Center, và you have sầu lớn clear them all together using the delete button located at the bottom.
Besides, the GTS 2 doesn"t show the corresponding icons of all the apps in the notifications, making it difficult to determine which tiện ích sent the notification. More so because the smartwatch doesn"t display the app name either. Not just that, the right swipe gesture to go to lớn the previous screen doesn"t work in the Notification Center, meaning you have sầu to scroll all the way up top to lớn go baông chồng khổng lồ the homescreen or press the physical button.
Music Control on the Amazfit GTS 2 worked as advertised, và since the smartwatch has 3GB of storage on board, you can load your favorite playlists and play them directly through the wireless earphones/speakers without requiring a điện thoại thông minh. Of course, you can also listen to lớn the songs through the wearable"s speaker if you prefer, but don"t expect anything extraordinary.
Offline voice control worked fine, although there were times the GTS 2 didn"t respond khổng lồ the voice commands. At the time of writing this, the GTS 2 lets you play/pause music, start/stop a workout, open an ứng dụng, or adjust some settings. Amazfit also rolled out Alexa tư vấn, but it hasn"t arrived on my unit yet.
Other nifty features of the GTS 2 include lockscreen password, screen rotation, & alert vibration customizations, making it easier khổng lồ identify different alerts without reaching for your smartphone.
The Amazfit GTS 2 packs a 246 mAh battery, which is claimed to lớn offer up khổng lồ seven days of autonomy with the following settings and usage:Heart rate monitoring always onSleep tracking enabled150 notifications a day which light up the screenDisplay turned on 30 times per day by raising your wristOperating the smartwatch at the highest screen brightness for 5 minutes each dayExercising three times a weekRunning for 30 minutes with GPS enabled
During my testing, the battery lasted no more than three days on average with the following usage and settings:Default watchfaceLift-to-wake screen enabledDisplay brightness at autoAlways-on display enabled for 17 hoursNotification & alarm volume set khổng lồ 50%Automatic heart rate monitoring interval set lớn one minuteSleep tracking enabledReceiving more than 100 notifications throughout the day which light up the screen & vibrate the smartwatch, consuming additional powerAround 20 minutes of indoor walking daily
Once the battery is completely drained, you can use the charger bundled with the GTS 2 lớn charge the smartwatch. Amazfit says it can fully charge the GTS 2 from flat to 100% in around 2 hours, but in my testing, it went from flat to lớn 100% in 1 hour 30 minutes on an average.
The Amazfit GTS 2 is a really nice smartwatch. It"s lightweight và comfortable to lớn wear, has a vibrant AMOLED display with good touch response, & the UI is smooth, too. Its 5ATM water resistance allows you to lớn traông xã your swimming performance, while accurate day & nighttime sleep tracking keeps you informed of your sleeping habits. The smartwatch also has 3GB of storage onboard, which means you can play music directly on Bluetooth earphones without requiring a smartphone.
Additionally, you also get a speaker & a microphone allowing you lớn take phone calls directly from the smartwatch when connected lớn the smartphone, and offline voice controls that let you operate the GTS 2 hands-không tính tiền.
But, the GTS 2 isn"t perfect. Its notification management needs improvement, và battery life is less than the GTR 2, which is expected since the cell itself is smaller (246 mAh vs. 471 mAh). Besides, the smartwatch doesn"t respond to voice commands at times, but that"s something Amazfit could hopefully improve with a software update. Additionally, redesigning the companion Zepp tiện ích would also be a wise decision since it"s quite a mess.
Answering the question asked at the beginning: the GTS 2 does come cchiến bại to lớn offering an experience similar to lớn GTR 2"s, but its lesser battery endurance could be a deal-breaker for some. And then there"s the GTS 2"s thiết kế. The smartwatch looks nice & elegant, but its relatively smaller footprint might deter some from buying it over the GTR 2, which comes with similar features và can be used for formal occasions as well. It comes in Sports and Classic editions. The former is priced the same as the GTS 2 in India right now, which is INR12,999 ($175/€145), while the latter costs INR13,499 ($180/€150).
And if you want something more sporty, rugged, & durable, then you also have sầu the option lớn go for Amazfit"s T-Rex Pro, which too costs the same as the GTS 2 in India at the time of writing. However, it doesn"t come with the speaker, microphone, offline voice controls, và internal storage for music playbachồng.
