  • This review is about the case size: 46 mm

    I bought it in June 2022, and used it without problems, mainly for exercise tracking and Google Pay. Until two weeks ago, when it turned off while charging and wouldn’t turn back on. Samsung’s service told me the screen, battery, etc. are burned out and the repair cost is about the same as a new one, so it’s going for recycling...

    This review is about the case size: 46 mm

    I bought it in 2023 for 160-170€ and now it has reached 400€. In my opinion, it is not worth more than 150€. Its battery barely lasts a day and it is not waterproof. I used it 4 times in the sea and it took in water. The store has very good apps but the more you have installed, the less the battery lasts.

    It was worth the money. After 4 years of use, the only thing that has worn is a bit of the color in some spots on the bezel. With daily use in the sea, mountains, etc., it hasn't suffered anything. The best choice in a smart watch.

    This review is about the case size: 46 mm

    The battery lasts a day and a half at most without all the sensors on. I went into the shallow sea for the first time after the second year with the water mode on to prevent water from getting in, and the board burned out. As soon as I charged it, it went into a boot loop. Nothing else is needed. Coming from the Huawei Watch GT, which lasted 14 days, I went back to the GT 4. 15 days of battery life and fully water-resistant

    The battery lasts the day only if you disable all useful features, e.g., you always have the screen and motion sensor turned off. Even to see the time, you have to press buttons. The blood pressure monitor is absolutely unreliable, as it always gives wrong readings by 2-3 units, even immediately after any calibration, as any slight movement on the wrist distorts the measurements. Only the heart rate measurement works reliably, but this is also offered by cheaper smartwatches costing 10 euros. I say this having professional experience with measuring devices.

    Despite its technological specifications, using apps from the screen of this watch is a torment that even the most diligent gadget enthusiast stops using after 5 minutes.

    Incredible watch, with amazing features such as high-precision counters, the ability to download apps from the play store, like google assistant, samsung internet, spotify, what's app, messages, calls, and many more. The only downside is the battery life which is about 1 day and something. Of course, it is an incredible watch and I highly recommend it.

    Supposedly it is certified for 5 atmospheres and swimming. I have had it for two years and for the first time I wore it during a bath in the sea. It worked okay for 10 minutes and then it just died, and I am forced to look for a new one.

    This review is about the case size: 46 mm

    The watch is flawless in every aspect, I have been wearing it daily for the past 4 months. The only "issue" is the battery life, which is mentioned in almost all reviews and was something I knew before purchasing it. With the usage I give it, it lasts barely a day and a half, but to have peace of mind every night, I charge it and it's okay for the next day. I don't know, of course, how reliable its measurements are in sports activities, and I don't have a point of comparison for them because I have never had a similar sport watch to know

    Coming from the first Galaxy Watch. Clear screen, better speaker on calls compared to previous models, comes with Android so you don't lose any functionality that exists on a phone (e.g. Google Pay, easily pay with the watch anywhere). The battery lasts a day and a half as stated by Samsung. A very good value for money watch, this purchase is worth it

    Very good watch even though I didn't expect anything less...2 years of use without any problem..I bought another one for my wife in a smaller size and it's equally good! The only negative thing is that if someone sends you a photo on messenger or somewhere else, you can't see it, while on the watch 3 it displays it normally.

    I have it for about 1 year. I am very satisfied. It syncs very easily and quickly with my Samsung mobile. It is convenient in hand and its functionality is exactly what I need. It feels wonderful to have all notifications and messages from Messenger on your wrist without having to open the mobile screen, especially when you are doing something or in other situations. The battery lasts about 2 days depending on usage, but this is not particularly important as I charge it every time I take a bath.

    The best thing there is for Android mobile devices. It has all the capabilities that a smartwatch can have without any compromise. Personally, I recommend buying the 4 compared to the 6 due to the price difference (which is justified due to more modern hardware), but the software it has installed is the best you can find. Battery life is about 1 and a half day as the website claims (40 hours).

    Aesthetically, it is amazing. As a smartwatch, it is pretty good although its battery lasts for about 2 days and takes a while to charge (definitely 1.5 hours). Its screen is very good and it has a good responsiveness. It is water-resistant (I take many swims in the sea) and it tracks well despite wearing it with a separately purchased bracelet (which doesn't help with the measurements)

    This review is about the case size: 46 mm

    Coming from the Samsung Watch 2 Classic, which I have since 2017 and still works perfectly, I can say that my choice was a one-way street due to the rotating bezel and its price, which is now 172 euros. The watch has nothing to envy from the equivalent Apple Watch (both in its positives and negatives, of course), and I use it with the Samsung Galaxy S22 Ultra. The only thing I did was to directly change its strap with a bracelet because it fits better on my wrist. As for the battery life that most people mention, it lasts me about 3 days with the night included when I have it off my wrist.

    The battery doesn't last a day in any case. Even if you put a good, purchased theme, it lasts at best 15 hours. Okay, it's tragic. If you're late for work, you're left without a watch. The rest is as you know it. Minor upgrades, even the 6 that came out 2 years later, are more or less the same. The competition has surpassed Samsung in terms of watches. Every year, it's the same

  • This review is about the case size: 46 mm

    I bought it in June 2022, and used it without problems, mainly for exercise tracking and Google Pay. Until two weeks ago, when it turned off while charging and wouldn’t turn back on. Samsung’s service told me the screen, battery, etc. are burned out and the repair cost is about the same as a new one, so it’s going for recycling...

    This review is about the case size: 46 mm

    I bought it in 2023 for 160-170€ and now it has reached 400€. In my opinion, it is not worth more than 150€. Its battery barely lasts a day and it is not waterproof. I used it 4 times in the sea and it took in water. The store has very good apps but the more you have installed, the less the battery lasts.

    It was worth the money. After 4 years of use, the only thing that has worn is a bit of the color in some spots on the bezel. With daily use in the sea, mountains, etc., it hasn't suffered anything. The best choice in a smart watch.

    This review is about the case size: 46 mm

    The battery lasts a day and a half at most without all the sensors on. I went into the shallow sea for the first time after the second year with the water mode on to prevent water from getting in, and the board burned out. As soon as I charged it, it went into a boot loop. Nothing else is needed. Coming from the Huawei Watch GT, which lasted 14 days, I went back to the GT 4. 15 days of battery life and fully water-resistant

    The battery lasts the day only if you disable all useful features, e.g., you always have the screen and motion sensor turned off. Even to see the time, you have to press buttons. The blood pressure monitor is absolutely unreliable, as it always gives wrong readings by 2-3 units, even immediately after any calibration, as any slight movement on the wrist distorts the measurements. Only the heart rate measurement works reliably, but this is also offered by cheaper smartwatches costing 10 euros. I say this having professional experience with measuring devices.

    Despite its technological specifications, using apps from the screen of this watch is a torment that even the most diligent gadget enthusiast stops using after 5 minutes.

    Incredible watch, with amazing features such as high-precision counters, the ability to download apps from the play store, like google assistant, samsung internet, spotify, what's app, messages, calls, and many more. The only downside is the battery life which is about 1 day and something. Of course, it is an incredible watch and I highly recommend it.

    Supposedly it is certified for 5 atmospheres and swimming. I have had it for two years and for the first time I wore it during a bath in the sea. It worked okay for 10 minutes and then it just died, and I am forced to look for a new one.

    The watch is flawless in every aspect, I have been wearing it daily for the past 4 months. The only "issue" is the battery life, which is mentioned in almost all reviews and was something I knew before purchasing it. With the usage I give it, it lasts barely a day and a half, but to have peace of mind every night, I charge it and it's okay for the next day. I don't know, of course, how reliable its measurements are in sports activities, and I don't have a point of comparison for them because I have never had a similar sport watch to know

    Coming from the first Galaxy Watch. Clear screen, better speaker on calls compared to previous models, comes with Android so you don't lose any functionality that exists on a phone (e.g. Google Pay, easily pay with the watch anywhere). The battery lasts a day and a half as stated by Samsung. A very good value for money watch, this purchase is worth it

    Very good watch even though I didn't expect anything less...2 years of use without any problem..I bought another one for my wife in a smaller size and it's equally good! The only negative thing is that if someone sends you a photo on messenger or somewhere else, you can't see it, while on the watch 3 it displays it normally.

    I have it for about 1 year. I am very satisfied. It syncs very easily and quickly with my Samsung mobile. It is convenient in hand and its functionality is exactly what I need. It feels wonderful to have all notifications and messages from Messenger on your wrist without having to open the mobile screen, especially when you are doing something or in other situations. The battery lasts about 2 days depending on usage, but this is not particularly important as I charge it every time I take a bath.

    This review is about case size: 46 mm, colour: Silver

    The best thing there is for Android mobile devices. It has all the capabilities that a smartwatch can have without any compromise. Personally, I recommend buying the 4 compared to the 6 due to the price difference (which is justified due to more modern hardware), but the software it has installed is the best you can find. Battery life is about 1 and a half day as the website claims (40 hours).

    I come from the Samsung Gear, the menu doesn't bother me, I've had it for 1 month, I don't have an opinion on the measurements if they are accurate but they work without problems, I will agree with the others about the battery that lasts a little over 1 day, I rarely use it to make calls but it works very well.

    Aesthetically, it is amazing. As a smartwatch, it is pretty good although its battery lasts for about 2 days and takes a while to charge (definitely 1.5 hours). Its screen is very good and it has a good responsiveness. It is water-resistant (I take many swims in the sea) and it tracks well despite wearing it with a separately purchased bracelet (which doesn't help with the measurements)

    This review is about the case size: 46 mm

    Coming from the Samsung Watch 2 Classic, which I have since 2017 and still works perfectly, I can say that my choice was a one-way street due to the rotating bezel and its price, which is now 172 euros. The watch has nothing to envy from the equivalent Apple Watch (both in its positives and negatives, of course), and I use it with the Samsung Galaxy S22 Ultra. The only thing I did was to directly change its strap with a bracelet because it fits better on my wrist. As for the battery life that most people mention, it lasts me about 3 days with the night included when I have it off my wrist.

    The battery doesn't last a day in any case. Even if you put a good, purchased theme, it lasts at best 15 hours. Okay, it's tragic. If you're late for work, you're left without a watch. The rest is as you know it. Minor upgrades, even the 6 that came out 2 years later, are more or less the same. The competition has surpassed Samsung in terms of watches. Every year, it's the same

    3 stars only for its battery, it barely lasts 40-45 hours. Compared to the first galaxy watch, which I had for 5 years and its battery still lasted at least 2 days (at the beginning it lasted at least 3 days). Other than that, it is a decent watch for its price
