You possess an Apple or a Samsung watch. The battery life has to be the most important thing to look at. We recently found the Amazfit GTR 3, which has a great battery.

Review: Amazfit GTR 3, GTS 3 Smartwatches

Design

• Case crafted from aluminum.
• Strap buckle 22mm universal
• Waterproof up to 5ATM

In the beginning, I think the design wasn’t all that interesting. Because I have the Amazfit GTR 3, it comes in Black, but it also comes in Grey. The watch happens with a 22mm universal strap buckle, so you can always buy a third-party strap that fits your style if you don’t like the default strap options.

Because this watch is made of aluminum, wearing it all day hasn’t been a problem for me at all. Regardless, the silicone straps that come with the watch are comfortable. The BioTracker PPG 3.0 sensor is on the back, and there are two buttons on the right for navigation and quick access to apps. There is a rotating crown and an extra button on the right.

A crown lets you scroll through options, open the app list, and act as the Home button on your phone. You can also make it do a certain thing when you long-press it. In my case, I’ve set it to call the voice assistant that isn’t on the internet at the moment. It’s also possible to change the button down below to open the exercise menu instead, but you can also change it to open any other function.

Display

• 1.39/1.75-inch AMOLED screen
• Always-on-Display dial, circular/square
• Peak brightness: 1000 nits

There is also the Amazfit GTS 3. If you prefer a square shape, you can get that instead. ‘S’ stands for squarish, and ‘R’ stands for the round. That’s how I separate these two smartwatch lines. Their specs are about the same, and they both have a lot of the same features for the same price because I like the way the GTR 3 looks; I bought it.

Okay, let’s talk about GTR 3. I think it looks great. With a screen that is 1.39 inches wide and 336 pixels per inch, it has an AMOLED cover with 454 x 454 pixels. And let me tell you, this is a great way to look at and interact with this.

The screen is AMOLED, which means you get deep blacks and great contrast. Now, even though its bezels aren’t the thinnest, when you set a dark-themed wallpaper here, the bezels look almost like they don’t even exist. When you look at this thing, you can see how well the contrast works. With 1000 nits of peak brightness, this smartwatch is bright enough even in the sunniest or brightest of situations because it has enough brightness to be seen even in the dark.

Similar to that, I haven’t had any problems with the Amazfit GTR 3 either. It takes a while to securely utilize the animations on the watch at first, but thanks to a recent update, everything runs smoothly again. There is only one thing that this screen doesn’t have: some protection for the screen. This is because it doesn’t have a physical bezel like Samsung’s Galaxy Watch 4 Classic, so it’s more likely to get scratches when it hits hard things.

• Tracking your health and fitness
• 150-sport mode with auto-detection of eight
• Monitoring of heart rate, SpO2, and sleep tracking

We’ll talk about how the GTR 3 can track your health and fitness in this part. You’ll detect all the things you want to track your heart rate and SpO2, as well as step and calorie counting. For the most part, it has what you’d expect. Here, there isn’t a way to keep an eye on the temperature of your skin, which is a little sad. I used a Huawei Watch GT 3 that had this feature in the past, but now you can get it on even cheaper phones. I can’t say much about their accuracy, though.

Readings might be off at times

However, I have to tell you that I’ve had some problems with SpO2 monitoring on the Amazfit GTR 3 and GTS 3 during my review. It scared me a lot when it showed low SpO2 readings, so I was very afraid. A different oximeter told me that my SpO2 level was at 98%, so I used that to double-check. I just thought you should know that.

The watch also has a PAI score based on the activities’ difficulty. Cardiorespiratory exercises make your PAI score go up more often each week. This photo, you can notice that my PAI score is very low, which means that my exercises aren’t very hard.

Over 150 ways to work out

In terms of fitness, the GTR 3 isn’t bad at all. You can do a bunch of various types of exercise here, from running, walking, biking, and swimming to hula hooping, skiing, frisbee, kite flying, and more.

Now, I’m not really into exercise, but I go for a run now and then. That built-in GPS worked very well for me at those times. You can also change the accuracy of the navigation system to save battery power in the settings, even though it takes a while to get the GPS signal set up when you first turn it on.

On the other hand, the automatic workout detection feature has very little to say about it, too. It isn’t as fine as the Galaxy Watch 4, but it isn’t bad either. As I said before, I go for outdoor runs a lot, and this watch would tell after around 5 or 6 minutes of running.

Can’t answer calls

Also, the GTR 3 has a built-in microphone, but you can’t make or receive calls here because it doesn’t have a speaker. It does, however, have call notifications. If you wish to consume a little more money, you can get the Amazfit GTR 3 Pro, making and receiving calls. You might want to get the “Pro” version instead if that is important to you.

When the GTR 3 first came out, it would just shut down and startup on its own without reason. This could be a deal-breaker for you. There have already been two updates, but the problem hasn’t been solved even though I’ve already used it. Amazfit may look into this quickly.

On the other hand, the watch supports Amazon Alexa and voice assistants that don’t work with the Internet. As a result, you can say things like “start a workout” “raise the brightness.” This means that you don’t have to touch anything. This isn’t a must-have feature, but it does make it easier to use the watch. And it’s also fun to use! Last but not least, the GTR 3 does a great job with the battery life, too.

Battery

• A 450/250-mAh battery
• Magnetic charger with two pins

Amazfit claims that its battery will last for 21 days, but I could only get about 12 days out of it when I kept all of the health functions on, the brightness level at 50%, and I used a live watch face.

Because all of these things use a lot of battery power, this is a dream come true for someone who doesn’t like having to charge their watch every day. However, if you buy the GTS 3, it doesn’t have as long battery life as it has a small battery. To charge your watch, you get a magnetic one in the box. It can charge your watch from 0% to 100% in about two hours.
