Huawei Watch 3 Pro: Smartwatch With Harmony OS

The Huawei Watch 3 Pro is the first smartwatch with the new HarmonyOS operating system. In contrast to the Watch GT models, which ran with LiteOS, Huawei now also uses the in-house operating system called HarmonyOS for smartwatches. It is an operating system used on smartphones, tablets, smart TVs, and many other devices.

The watch is definitely not a bargain. Everyone has to answer for themselves whether the high-quality materials and the impeccable quality justify the high price.

The watch case is made of titanium, and the bottom is made of ceramic. The display is also protected by scratch-resistant sapphire crystal. In addition, the Elite model comes with a very nice titanium link bracelet (+ a replacement bracelet made of skin-friendly silicone).

It looks quite massive on delicate wrists. This is because it has a diameter of a full 50 millimeters, including the black bezel (exclusive to the Pro model).

On the other hand, the watch body is quite thick and, at 63 grams, not exactly light. Why is it like that? Well, it is mainly due to the fat 790 mAh battery, which enables a good runtime. It has to be housed somewhere. More about the battery life can be found almost at the end of the review.

The Huawei Watch 3 Pro is operated via a colorful and bright 1.43 inch AMOLED display with 466 x 466 pixels. In addition, there is a rotatable and pushable crown on the right side. The Apple Watch probably inspired Huawei. The crown also provides pleasant haptic feedback (vibration).

Next to the crown, we find another button a little further down. You can freely assign a function, for example, opening the training mode. Both the crown and the button have a very comfortable pressure point and are of high quality. A nice detail: “Huawei Watch” is engraved on the crown.

Huawei particularly highlighted the thermometer at the presentation. In fact, the watch can also measure skin temperature. A function that I don’t think is available on any other smartwatch. However, everyone has to decide for themselves whether it makes sense or not.

Huawei packs a lot of technology into the massive watch body. Incidentally, this is waterproof up to 5 ATM or 50 meters. For our fans of technical details: The HiSilicon Hi6262 processor clocks under the hood and is flanked by 2 GB of RAM. The internal storage space amounts to a whopping 16 GB. The processor also offers a 4G modem. Thanks to eSIM support, the smartwatch can operate independently without a smartphone.

Other sensors include an accelerometer, gyroscope, barometer, heart rate monitor, an SpO2 sensor. The heart rate, the oxygen content in the blood (SpO2), and the skin temperature can be continuously recorded on request.

For the first time, Huawei is using what is known as dual GPS to determine position. It should enable an even more precise recording of workouts outdoors. We have, of course, taken a very close look at this for you. You can find out more about this under “Activities & Workouts.”

The watch connects to your smartphone or an accessory in the form of Bluetooth headphones or chest straps via Bluetooth 5.2. There is also an NFC chip in the watch. However, since there is no payment app available for it, the NFC chip does not really make much sense at the moment. Or, to put it another way: it is there, but you cannot use it.

Huawei has integrated a microphone and loudspeaker in the case. If the smartphone is not at hand or the watch is used independently via the integrated 4G modem, you can also use it to hold calls. However, you shouldn’t be surprised that the sound quality of the speaker was only partially convincing.

And what is still missing? Well, to be honest, I was hoping that Huawei would also put an EKG sensor in the Huawei Watch 3 (Pro). It’s a feature that I think is really very useful. But that’s exactly what is missing from the latest Huawei smartwatch for some reason. Too bad.

Harmony OS

The new HarmonyOS is better than LiteOSs used on the previous Huawei smartwatches of the GT series. But it’s not perfect yet – not at all.

The setup is simple as usual or is based on the previous model. Before you start, you have to ensure that you have the latest Huawei Health app installed on your smartphone (Android or iOS). You don’t get them in the Google Play Store but in the AppGallery.

In fact, the version on the Google Play Store is out of date and has not been updated for a long time. As we learned from Huawei, it’s not their fault; it’s Google. Allegedly, Google is preventing a direct update via the Play Store due to the US sanctions. Let’s stand like that.

HarmonyOS runs smoothly and stably on the Huawei Watch 3 Pro – especially since the last software update. Operation is simple and, in my opinion, implemented intuitively. Anyone who already had a Watch GT smartwatch will find their way around quickly. Yes, even the pre-installed apps are identical.

The main menu is opened by pressing the crown once. The main menu is very reminiscent of the look of the Apple Watch. We don’t find it tragic but rather practicable. If you prefer to have a list view, you can, of course, select this in the settings.

A swipe down opens the quick settings, and a swipe up opens the notifications. Pleasing: The Huawei Watch 3 (Pro) finally also supports emojis. However, it is not yet possible to reply to messages today, although a keyboard app is already on board.

In addition to the ability to reply to messages, Huawei should generally look at the notification function. The problem: If notifications are read on the smartphone, they remain on the watch – and vice versa. Other manufacturers have solved this better.

The AppGallery is preinstalled on the Huawei Watch 3 (Pro). This is what Huawei calls its own “app store.” However, anyone who expected a large range of apps will quickly be disappointed. So far, there are no inspiring apps in the AppGallery – at least not for me.

Overall, the offer is still very sparse and, therefore, manageable. There are no streaming apps of any kind, such as Deezer, Spotify, Tidal & Co. There are also no sports apps such as Strava or Adidas Running (Runtastic) available for HarmonyOS.

Of course, the range of apps can still improve in the coming weeks. After all, the watch has only been available for a few days. However, it will not be that easy to convince the app developers for a smartwatch, which is (yet?) Not very widespread.

Activity Monitoring

Step CountYes
Heart Rate MonitorYes
Alarm ClockYes
Date & Time DisplayYes

In terms of activities, the Huawei Watch 3 leaves little to be desired. The watch reliably records all your activities (steps, activity minutes, etc.) and vital data (heart rate, SpO2, temperature, and sleep quality). These values ​​are then synchronized with the health app, enhanced with diagrams and additional information.

The Health app for Android and iOS not only shows you all the relevant fitness and health data, but you can also use it to transfer new watch faces (dials), manage the notifications, and determine whether the heart rate, the oxygen content in the blood and the temperature measurement are continuous should be measured.


There are over 100 different sports to choose from for the workouts. You can start the workout using the lower button, provided you have not assigned another function to the button. In addition to the classic sports such as running, cycling, or swimming, there are also less popular training modes for, for example, HIIT (high-intensity interval training) or kendo.

During the training, the smartwatch nicely prepares all relevant data. There is also a “virtual” language coach who keeps you updated on how you are currently on the move. However, this only acts in English, which may bother some of you.

The Chinese manufacturer offers dual-channel GPS support for the Watch 3 Pro. As a result, Huawei promises, on the one hand, a faster position determination and, on the other hand, an even more precise recording of the distance covered. But is that also true?

The Huawei Watch 3 Pro was able to determine my exact position very quickly outdoors. There are still deviations in the recording in the forest in the running training, but they are noticeably lower than with the Huawei Watch GT 2 Pro – without dual GPS.

The heart rate measurement values ​​are a little less accurate in workouts. Here the Watch 3 Pro holds back a little too much so that the value is ultimately too low. I compared the values ​​with a Polar heart rate belt. Huawei absolutely needs to make improvements here.

Speaking of running: In the settings under “Security and data protection,” fall detection with an automatic SOS emergency call is hidden. Priority must be given to determining an emergency contact via the health app. The user can also store additional data, such as allergies or blood groups, for example.

The smartwatch has automatic training detection. As soon as active, the fitness tracker recognizes whether you are training based on the activity intensity and reminds you to start the respective training. This works fine for running, walking, cross-training, and rowing.

The training sessions are, of course, synchronized directly with the health app on your smartphone. It works well and seamlessly. Unfortunately, Huawei still doesn’t offer direct integration with third-party apps like Strava. Unfortunately, the workouts cannot be exported as GPX or similar files.
Thanks to the Health Sync app iff you want to transfer your training from the Health app to Strava, you can still do s. This works very well as long as you follow the instructions for the Health Sync app.


The 790 mAh battery is definitely noticeable. What does that mean in concrete terms? With an activated Always-on-Display (AOD), the continuous measurement of the heart rate, the oxygen content in the blood, and the temperature measurement. You will get get exactly two days of running time.

Another two days of running time can be tickled by switching off the always-on display from the Huawei Watch 3 Pro. Isn’t that enough? Then you can switch the watch to energy-saving mode. If this is activated, the watch switches to a restricted mode. This is reminiscent of LiteOS from the Watch GT series. Although heart rate & Co. is still recorded, time can extend the runtime up to 14 days.

The Huawei Watch 3 Pro is charged via induction wireless charging. The scope of delivery includes a small charging station that is magnetically attached to the watch. A complete charging process from 0 to 100 percent, therefore, takes about three hours.


The Huawei Watch 3 Pro Elite is an extremely chic premium smartwatch, which shines with excellent quality and high-quality materials. That has its price. The Chinese manufacturer is charging 599 francs for its latest piece of jewelry. This price is understandably a deterrent.

But the watch only convinces with its extremely chic and high-quality design but also offers a lot of technology under the hood. Thanks to the many integrated sensors, the user gets a comprehensive overview of his vital data. Here, however, we would have liked an EKG sensor.

Otherwise, the watch can be used without a smartphone thanks to the integrated eSIM – albeit with restrictions. Unfortunately, it is not yet possible to reply to messages directly via the watch – not yet.

HarmonyOS for smartwatches (and also for smartphones) is not yet ready. Apps and services are still missing, such as a payment app like Google Pay / Apple Pay or a map like Google Maps or Petal Maps. At least the latter is planned, as Huawei has assured us.

Yes, Huawei still has numerous assembly sections to take care of. And yes, maybe Huawei should have waited a few more months before releasing the Watch 3-Series to complete all of its planned apps and services first.


Best Smartwatches for Seniors

Smartwatches and bracelets are convenient, and most importantly, handy gadgets that allow you to monitor your health effectively. They can be used to monitor heart rate, blood oxygen levels, body temperature, and even sleep quality. The best models detect deviations from the norm and can also offer a solution to the problem. All this is very important for the elderly, especially in the context of the COVID-19 pandemic.

Manufacturers are trying to add as many useful functions as possible to smartwatches and bracelets, making it difficult to manage them. Savvy users can grasp new technologies quickly, but for older people, it can be not easy. We have selected several models that, in my opinion, are suitable for older people both in terms of capabilities and ease of operation.

Xiaomi Mi Smart Band 6

The main advantages of these smart bracelets are their effortless operation, have good screen brightness, and relatively low cost. At the same time, it helps to keep track of health and tracks the overall level of physical activity. With moderate use, the bracelet can last up to 14 days on a single charge.

The sixth version of the Xiaomi Mi Smart Band has a larger screen compared to the fifth version and, thanks to the increased size, the font is better to read. The updated version of the alarm clock can now be configured directly on the bracelet itself without using the application, which is also very convenient.

By default, the bracelet comes with several convenient dials that are very easy to switch and customize. There are customizable widgets on modular watch faces and the main part of the screen, where the time is usually displayed. With the help of widgets, it is easy to display a variety of indicators on display yourself, for example, heart rate, number of steps, weather, or oxygen level in the blood. In addition, the bracelet can track stress levels and monitor sleep quality. During a street walk, the system will inform you about the level of humidity, UV intensity, and air quality.

The measurement of the personal activity index deserves a separate mention. The bracelet tracks the user’s actions for several days and converts all the information received into one standard indicator. Such information helps to adhere to a certain rhythm of life and always stay in good shape, which is always very important for an older person.

HONOR Band 6

The HONOR Band 6 is a direct competitor to the Xiaomi Band 6, which we reviewed above. Both bracelets have a very similar feature set and similar tracking capabilities for health and activity levels. However, there is also a difference between gadgets.

If the model from Xiaomi, due to its narrow screen, completely follows the canons of the classic architecture of bracelets, then the HONOR Band 6 can be called a transitional option. It has a wider display, due to which the gadget looks larger, and there is a mechanical button on the body that helps to control some functions. In this design, the tracker is even more familiar to the elderly.

The HONOR Band 6 is equipped with sensors that measure heart rate and blood oxygen levels. The system records estimated calorie consumption, monitors stress levels and sleep quality, counts steps, and collects weather information. The bracelet allows you to control music, set the alarm, and send messages about incoming calls.

Nevertheless, there is no way to answer voice calls, and there is no GPS tracker that allows you to control the user’s movement without using a smartphone. Another disadvantage of the HONOR Band 6 compared to the Xiaomi model is the smaller choice of installed watch faces. Some versions of the dials are paid at all.

In terms of cost, the HONOR Band 6 is comparable to the model from Xiaomi, but in terms of usability, it slightly outperforms its main competitor due to the more comprehensive screen.

Canyon Lemongrass Smartwatch SW-70

The Lemongrass CNS-SW70 model is recommended if you need a spectacular and, at the same time, inexpensive gadget with good functionality. The cost of this smartwatch is comparable to the cost of the Band 6 fitness bracelets from Xiaomi and HONOR.

The main advantage of the Canyon Lemongrass CNS-SW70 is its stylish design. The slim round dial is secured on a beautiful metal strap with a magnetic buckle. The IPS screen in sunlight is not as bright as the AMOLED displays on the Band 6 fitness trackers, but the values ​​are quite distinguishable. Even though the clock’s shape is round, the display area on the screen is square. Users often criticize this decision; however, the design of the dials takes this feature into account, and watches with the screen turned on do not lose their presentability.

In terms of the set of functions, the Canyon Lemongrass CNS-SW70 watch resembles a classic fitness tracker: it measures the heart rate, counts the number of steps, the number of calories burned, and tracks the overall level of physical activity. They have a smart alarm and sleep monitoring mode. As for the quality of measurements, it, like in many inexpensive models, has some errors that should take into account. With moderate use, the watch can last up to four days on a single charge.

The Canyon Lemongrass CNS-SW70 watch is well suited for seniors who value design. In addition, this model is an inexpensive chronometer that helps the user effectively monitor their health, which is why it enjoys a certain popularity.


The HUAWEI WATCH GT 2 Pro smartwatch is one of the best Android models in the premium segment. The main advantages of this gadget are its spectacular design, excellent screen, and case protection, long battery life, and the ability to answer phone calls. In addition, it contains all the most essential functions to keep track of your health and physical activity. It is also easy to operate the watch, thanks to which it may well become a suitable replacement for ordinary wristwatches.

It’s hard to find fault with the appearance of the HUAWEI WATCH GT 2 Pro. They not only look beautiful but, in all respects, fully correspond to a premium smart chronometer. The case is made of durable titanium alloy. The part where the watch touches the hand has a ceramic insert. The strap is made of genuine leather. The display is covered with a sapphire crystal, which is well protected from scratches.

Good battery life is another important plus of this model. With moderate use, the watch can last up to 14 days, but one charge is often enough for about 11-12 days.

HUAWEI WATCH GT 2 Pro can measure heart rate, blood oxygen levels, count steps, and monitor sleep quality. They have a barometer and an intelligent alarm clock; the watch synchronizes with a wireless Bluetooth headset and allows you to listen to music while walking, even if the phone is left at home. And most importantly, this watch has a compass and a GPS tracker. Older people on tourist trips and during out-of-town walks come in handy with the function of moving on the return route. To find your way home, you need to move in the direction indicated by the clock.

Apple watch series 6

Smartwatches Apple watch series 6 can be recommended to happy iPhone owners. Compared to the fifth, the sixth version slightly added to the set of functions, so owners of Apple watch series 5 or even Apple watch series 4 do not need to change their gadget. Of the exciting innovations, we can only note the emerging sensor for measuring the oxygen level in the blood and a reduction in the charging time by about 20 percent. The design of the sixth version has hardly undergone any changes, except that models in blue and red have been added.

Nevertheless, suppose we compare the Apple watch series 6 with any other smartwatch in terms of convenience and the number of valuable functions. In that case, they leave far behind all their closest competitors. Suffice it to say that in order to operate this chronometer, an older person does not need to figure out how to turn on or off one mode or another. The watch supports the voice assistant Siri, which means that you can control all functions just with your voice.

In Apple watch series 6, heart rate and blood oxygen levels are measured not by pressing buttons but in a continuous mode, which allows you to build a full ECG throughout the day and monitor breathing without interruption. In the context of the COVID-19 pandemic, it is difficult to overestimate the usefulness of such features. The system monitors physical activity, sleep quality, and calories burned. The watch has a light sensor, accelerometer, gyroscope, and altimeter.

The only drawback of Apple technology is its high cost, which fully applies to the Apple watch series 6. However, we can confidently say that this watch will last for many years with careful handling, and its benefits for an older person will be invaluable.

Fitbit Charge 5 vs Fitbit Charge 4: Which is Better

After a series of leaks, Fitbit has announced a new generation of Fitbit Charge 5 fitness bracelets. This is the first wristband made by Fitbit since Google acquired it. Due to the relatively high cost and low availability of Fitbit fitness bracelets, devices from this line are not very popular in our market. Nevertheless, we decided to compare Fitbit Charge 5 and Fitbit Charge 4, find out how they differ, and it is worth selling your Charge 4 and ordering a fifth-generation tracker. Let’s start with the comparison with the main technical characteristics.

Check out detailed review here: Fitbit Charge 5

Over the years, since the first tracker in the Charge family came out, Fitbit has followed the same design. So, to find the external difference between the Charge 4 and its predecessor Charge 3 is quite difficult. The new Fitbit Charge 5 has received the most noticeable design change since the first generation.

Fitbit Charge 5 received smoother lines and rounded design, became a little thinner and more comfortable than its predecessors. Charge 4 measures 35.8 mm x 22.7 mm x 12.5 mm, while Charge 5 measures 36.78 mm x 22.79 mm x 11.2 mm. That is, Charge 5 is slightly larger, but thinner by almost 10%

Fitbit Charge 5 and Charge 4 lack a mechanical button on the case. But, instead of the usual control, the fourth generation tracker has small notches on the sides; when pressed, the tracker is activated (capacitive button). The metal inserts on the sides of the Charge 5 can also be mistaken for a capacitive button, but they are ECG sensor electrodes. All control is carried out using the touch screen.

Both fitness trackers are water-resistant to 50 meters and come with large and small straps. The Charge 4 is available in black, blue, Rosewood, and a particular version with a black case and fabric strap. The Charge 5 is available in black, silver, and gold.

The hook Type of the strap has changed. Now it is not a classic clasp but a “tip-in” pin clasp.


The display is the second major update after the design. The new generation, unlike the Charge 4, which has a monochrome OLED grayscale screen, has a color AMOLED display with higher resolution and brightness. The Charge 5’s 1.04-inch screen with a maximum brightness of 450 nits is 10% more than its predecessor (Charge 4’s brightness is 200 nits). Its resolution is 260 x 170 pixels, versus 160 x 100 pixels for the previous model.

Fitbit Charge 5 has an Always-on Display feature and an ambient light sensor to adjust brightness automatically.

In terms of sensors, the Charge 4 features a 3-axis accelerometer, PPG optical heart rate sensor, SpO2 sensor, altimeter, skin temperature sensor, and built-in GPS for more accurate tracking of outdoor activities like running and cycling.

The Charge 5 has all of the above equipment except the altimeter. Perhaps they abandoned it because users often complained about its accuracy. But this is just our guess.

The new 5 series comes with electrocardiogram (ECG) sensors and an electrodermal activity sensor. The latter allows you to assess the body’s response to stress. Also, both models are equipped with an NFC module for contactless payment (Fitbit Pay payment system).

Advance Features

NotificationsYes Yes
NFCYes Yes
EDA sensorYes No
ECG sensorYes No
Heart rate monitorYes Yes
Step counterYes Yes
Swim-proofYes Yes
Stress level trackerYes No

Both generations of a fitness bracelet can perform the following functions:

  • Sleep Score;
  • Smart alarm clock (Smart Wake);
  • Monitoring of multiple sports modes (indoor and outdoor);
  • 24/7 heart rate measurement (PurePulse); Determination of the level of blood oxygen saturation (SpO2);
  • Call and message notifications with support for fast message reply;
  • Control of menstrual cycles; Activity reminders; Spotify Music Play Control Connect & Control;
  • Heatmaps of workouts (after a run, a route map with heart rate zones for each leg of the route will be available)

The Charge 5 has several new features:

  • Daily Readiness Score. This functionality is only available with the purchase of a paid Fitbit Premium subscription ($ 10 per month). Depending on the user’s activity, sleep duration, and heart rate, the bracelet will offer a more intense or light workout.
  • ECG recording function to evaluate the work of the heart and detect signs of atrial fibrillation. To take readings, you need to touch the conductive inserts on the ends of the case with your fingers.
  • Determination of stress levels with electrodermal activity sensors (EDA)

The rest of the functionality of this pair of trackers is almost identical.


For Charge 5 and Charge 4, the manufacturer claims the same autonomy. The battery charges to 100% in about 2 hours, and one charge will last up to 7 days of use. With GPS always on, the charge lasts for 5 hours.

When you enable the Always-on Display function, the Charge 5 will work without charging for about 2 days


The Charge 5 was priced at $ 179.95, which is $ 30 more than the Charge 4 was priced at when it was announced. Usually, soon after a new version is released, Fitbit and most retailers will drop the price of the previous generation. That is, you can expect that the difference in cost will soon be $ 40 – 50.


The main improvements to the Charge 5 are a more modern design, color AMOLED display, ECG, and electrodermal activity sensors. If you can come to terms with the lack of all of the above, selling your Charge 4 is probably not worth it.

Samsung Galaxy Watch 4 vs Apple Watch Series 7: Which is Better

The Apple Watch Series 7 and Samsung Galaxy Watch 4, two advanced smartwatches with much to offer, now face each other in this comparison to measure forces. The first is the newest, a few weeks after being announced, while the other arrived in August of this year. Both are among the complete today, both in terms of features and technical specifications and functions. That is why now faces are seen, to demonstrate which is better and why. We analyze them!

To begin with, the Apple Watch Series 7, recently, is the new smartwatch from the Cupertino firm and, therefore, the most advanced in its catalog. This smartwatch comes with several improvements over the Apple Watch Series 6 that we make clear in this article, and that is why it is one of the best options in the current market.

The Samsung Galaxy Watch 4, for its part, is also the best Samsung smartwatch. By far, it is also equipped with qualities that make it another of the best and most complete alternatives today, both for having a design very well worked and elegant as for being a watch that competes directly with the Apple as mentioned earlier Watch.

Crisp, vibrant OLED displayBig screen is more user-friendly
Touch-sensitive rotating bezelwatchOS 8 is powerful
Good fitness/sleep trackerQWERTY keyboard
Concerns with BIA sensorNo Qi charging
One-day battery life One-day battery life

The first thing to highlight about both wearables is the design section. The Apple Watch Series 7, as in past generations, has the same rectangular format as always, which is what we are used to. Of course, this watch comes with fewer screen frames than before, so its full-screen design is now more striking, having quite reduced edges. From the rest, we get practically identical:

  • Interchangeable straps.
  • The usual crown.
  • The slot for the eSIM.
  • An aspect that is generally the same, both elegant and sophisticated and casual and sporty.

The Samsung Galaxy Watch 4, on the other hand, has a circular format, like other previous models of the South Korean firm. Of course, this smartwatch changes in several aspects. Its predecessor, the Galaxy Watch 3, is more stylish and elegant, but without leaving the sporty aside, with a watch face with reduced frames and well-polished sides. With various buttons.

Moving on to the issue of screens, we find several differences between the two smartwatches. And it is that the Apple Watch Series 7 has a screen that consists of a diagonal of about 2.1 inches approximately-This data has not been specified by Apple-, being more prominent than that of the Galaxy Watch 4, which is 1.4 inches in the 46 mm version and 1.2 inches in the 42 mm version. At the same time, the panel of the former is of retina OLED technology. It has a resolution of 448 x 360 pixels, while that of the Samsung watch is of Super AMOLED technology and consists of a resolution of 450 x 450 pixels. In addition, in both cases, we have color screens, touch screens, and 2.5D borders. The other thing is that both are protected with resistant glasses that stand up to scratches, bumps, falls, and all kinds of abuse.

In terms of performance, the Apple series 7 comes with 64-bit dual-core processor is a chip choice to live under the hood of the Apple Watch Series 6. The Exynos W920, on the other hand, is aimed at the Samsung Galaxy Watch 4. Both one and the other consist of dual cores and architecture. 64-bit, being quite solvent to run any app and task fluently. Of course, for storage, the Apple Watch is better, as it comes with an internal memory of 32 GB, which is double that offered by the Galaxy Watch 4 since the smartwatch has a ROM of 16 GB. They both support the storage of music, apps, pictures, and more.

In the connectivity section, there are no significant differences. They coincide the most, so much so that they share all the available options that we can find in an advanced and high-caliber smartwatch-like these, which leaves us with support for 4G LTE networks, dual-band Wi-Fi, Bluetooth. 5.0, integrated GPS with A-GPS, GLONASS, Galileo, and NFC for making contactless payments. Apple Pay is available on the Apple Watch Series 7 and Samsung Pay on the Galaxy Watch 4.

Now, something that these smartwatches do not lack, but, on the contrary, they have a lot to boast about, is their sensors and monitors. And it is that both one and the other come with an ECG monitor capable of detecting and monitoring the heart rate and abnormalities related to atrial fibrillation. Both also come with a blood oxygen level measurement sensor and features that allow recording the user’s sleep quality and more.

The two also boast a barometric altimeter, gyroscope, accelerometer, and ambient light sensor. For the rest, they come with numerous functions that allow you to know the distance traveled, calories burned, steps taken, and more. Both can also detect multiple sports and track cycling, swimming, running, and outdoor leisure activities.

As for the battery, the Apple Watch Series 7 loses, having autonomy of up to 1 day on average. The Galaxy Watch 4, on the other hand, is capable of reaching a battery life of up to 1 week, being the winner in this section.

Features of these smartwatches include water resistance, fall detection function, emergency calls, weather forecast function, notifications for both calls and messages and applications, and more. Of course, only the Samsung Galaxy Watch 4 has MIL-STD-810G military-grade resistance, so it has durability far superior to that of the Apple Watch Series 7. Of the rest, the first has Siri as a voice assistant, while the second has Samsung’s Bixby. You also have to acknowledge that the Apple Watch comes with watchOS 8 and the Galaxy Watch 4 with Wear OS powered by Samsung.

The price of the Apple Watch Series 7 starts at 420 USD officially. Samsung, for its part, launched the Galaxy Watch 4 from about 250 USD in the smallest variant and without 4G LTE connectivity.


Finally, it is worth noting that we have two of the most complete and advanced smartwatches of the moment. It is difficult to determine which is better and why since each has its strengths and advantages. However, we rate the Apple Watch Series 7 as the winner of this comparison for having a larger screen and more storage space.

Of course, the Galaxy Watch 4 is a better option if you want a cheaper watch and with practically everything that the Apple Watch offers, with an addition that includes military-grade resistance, more battery, and more customization options.
