A very good purchase at around €200. Apart from some synchronization issues during the first use, and after many resets on the first day, the watch connects steadily and continuously to non-Samsung Android phones.

It is important to grant the necessary permissions, Autostart, as well as to disable the battery saving function for Samsung Wearable and Galaxy Watch4 Plugin apps through the mobile's App Settings. If your phone automatically closes these apps, there may be connection and synchronization issues.

The Samsung Health app is very satisfactory and personally, I find it better than Google Fit so far. The Samsung Health Monitor app is the one you will need to sideload if you want the blood pressure and electrocardiogram to work (as it is only available on Samsung phones). For those who are familiar with cmd on Windows, adb, and have 5-10 minutes, they can find online the relevant instructions and necessary files to enable Blood Pressure and ECG on non-Samsung Android phones.

There are satisfactory options on the Play Store for more interesting and useful Watch Faces than those provided by Samsung with the watch, however, empirically I would say that it is worth spending 2-3 euros for a watch face that satisfies aesthetically and functionally as the best ones are paid and provide flexibility with widgets (shortcuts for apps and functions) on the home screen.

Finally:

it is positive that it supports Google Pay for payments (with banks that support it),
negative that it does not currently support Google Assistant (as there is no Google Home app for Android Wear),
and a mediocre battery situation that definitely lasts a day of use but not more if used extensively. It would be better if it had fast charging, but 0-100 takes 2 hours.

If you want to rely on the battery and charging of the smartwatch, then it's ideal. Daily charging can be tiring. Yes, it has all the features it has (only when connected to android), but that's about it.

  • This review is about the case diameter: 40 mm

    The build quality seems very good. The measurements and all the tools it has are also flawless. But guys, it doesn't last 12 hours without any special use... You can't take it off every so often and charge it a little. I wouldn't buy it again if I could choose due to its terrible battery.

    This review is about the case diameter: 40 mm

    After 2 days of having it, it turned off as soon as I entered the sea. It has been sent for service and I am waiting to see what they will tell me. I want a refund after this and not a replacement. Of course, I am waiting to see if they will find the product faulty or if they will say something else. I am waiting and will return with any updates. They took it back and returned my money. Scrut 5-star guarantee for this

    In everything else it is good but this battery suffers... It does not have a long autonomy, only that, it needs to be charged every 2 days for sure. What a pity...

    First time smart watch owner. Overall, I am satisfied with its features. The battery needs to be charged every day/day and a half, but reading the reviews you expect it and eventually it doesn't bother me so much. For ECG and Blood Pressure you need to have a Samsung mobile to install the app, but with a little searching and a little trial and error you can find the modded Samsung Health Monitor app that allows you to bypass the restrictions and install it on your mobile.

    Very good watch even though I didn't expect anything less...2 years of use without any problem..The only negative is that if someone sends you a photo on messenger or somewhere else, you can't see it while on watch 3 it displays it normally.

    I literally threw away 150 euros because its battery doesn't last even 24 hours! Everything else is very good, but you need to charge the watch every day. I have an older watch that lasts at least 15 days. Unacceptable, I do not recommend it

    Nice watch, I bought 2 for my children, rich features, but what I didn't take into consideration at all was the battery life. I really see them charging it every 1-1.5 days. The only, but significant reason why it's not worth its money. At least I hope the battery life is long, let's wait and see.

    I am very disappointed with the product.
    The synchronization with your mobile is not so easy.
    The bracelets are made with very low-quality silicone.
    The battery duration is ridiculous, I need to charge the watch every day. For a smartwatch that costs more than €200, the battery should last at least 1 week.

    I will try to sell it and buy another one more capable and with a lower price.

    The smartwatch is excellent! I've had it for 2 weeks and I'm still discovering new features of it. I have the 40mm as I have a very small wrist and it looks beautiful! The only negative is the battery life. With moderate use and enabling battery saving mode at night, it needs to be charged once a day! However, it charges very quickly! I highly recommend it!

    I have had the watch for a year and a half, the battery issue that everyone mentions is indeed a problem but it doesn't bother me. With all the apps I need and if you adjust it correctly, it lasts until late afternoon with 20% remaining and it's enough for me. In terms of durability, I have to say it's 5 stars and more, I don't take care of it at all, I have hit it many times and the screen withstands and its definitely waterproof as I have gone swimming with it

  • Very good choice especially for the price you can find it today, value for money purchase.
    Measurements are flawless, very nice in the hand and upgrades until 2025.
    It works 100% and delivers all the capabilities it has only with Samsung mobiles.
    Battery is average but okay. It takes a while to charge but it doesn't bother me at all.

  • This review is about the case diameter: 40 mm

    Depending on the use each person makes of it, they find it either perfect or rubbish. It is a complete health assistant with measurements of heart rate, oxygen, blood pressure, and electrocardiogram. As for the negatives, it has a small battery for these data. It lasts for 2.5 days with basic functions and not continuous medical monitoring. The measurements are accurate, but as we said, it depends on the use you want.

    This review is about the case diameter: 40 mm

    Quite a good choice for a watch, it has many positives such as sleep tracking, heart rate monitoring, and others. But what bothers me is that it requires constant measurements for blood pressure with another measuring device in order to measure my blood pressure. Overall, it is quite useful. I wouldn't recommend buying such an expensive smartwatch as your first one, and definitely not for small children, it's a waste of money. Also, I suggest buying something to protect the screen along with the watch. I had an issue where the screen got scratched, after all

    Bought 4 months ago for €145, great value for money!!!
    Very good screen, waterproof in the sea, Google Pay for contactless payments, very good microphone and speaker, wireless charging, but only with its charger or with wireless sharing on the back of a Samsung mobile phone in the S series models. (It's true that because the battery doesn't last more than 1.5 days, it has become inconvenient for me. I don't carry the charger with me anywhere and I charge it at night on my phone).
    Finally, you can reply to written messages on all applications, and of course, you can make calls from the watch to any contact and even type a number outside of contacts.
    I gave it 4 stars because of the battery and the limited range in connecting to the mobile phone.

    This review is about the case diameter: 40 mm

    Although I had read reviews about the battery, I did not expect it to be so bad. Without activating the screen by shaking my hand, without wifi, NFC, low brightness, and without decent functions, it barely lasts a day and a half. If you exercise and use it, it lasts less than a day! However, the biggest disappointment is the measurements in open water. You can swim 50 meters and the measured distance is stuck. In cheaper watches, the measurements are much more accurate. On the positive side, it has a lot of activities, but with such inaccurate measurements in swimming, I doubt its reliability. I will definitely not say that it is worth the 135 euros I paid...

    Everything is good, the screen, hardware, and overall everything, but I removed one star for two reasons:
    1) It has many useful features and futures that are only for Samsung mobiles, which is very negative.
    2) The battery is not very big and barely lasts a day, but this doesn't bother me much because I always charge everything at night.
    I highly recommend it (especially if you have a Samsung mobile)

    The reason why I remove one star is due to two disadvantages:
    1) Some features are exclusively accessible to Samsung mobile owners.
    2) Short battery life, requiring daily charging, which combined with the two-hour charge time from 1 to 100%, can be a bit tedious.
    Otherwise, it is worth its money.
