Umidigi Uwatch 3S - An Honest Review

Umidigi followed up the debut of the Uwatch 2s with the launch of its improved variant, the Uwatch 3s, and then produced two further versions, the Urun and the Urun S.

It’s been quite some time since we last covered any smartwatches on this site. So today, we will be looking at one of the most current affordable smartwatches, the Umidigi Uwatch 3s.

We will talk about what the new features of the Uwatch 3S are. To whom does this pertain? Is it worth your cash? as well as a contrast with some of Umidigi’s other recent models.

Umidigi Uwatch 3S Style & Screen

Display-wise, the Umidigi Uwatch 3s takes after its predecessor, the Uwatch 2s, and features a spherical form factor. It weighs roughly 30 grammes with a strap; you will be getting a lightweight sensation using it.

The fact that thermoplastic polyurethane (TPU) was used in the construction of the straps confers upon them the characteristics of being exceedingly flexible, long-lasting, and silky to the touch. In addition to that, the clasp has a gunmetal finish, and a logo has been carved onto it. Because the straps are detachable, you may always modify the watch by replacing them with another 22mm strap of your choice.

In addition, there is no actual button on either side of the device. You get a button with a touch interface, just like on fitness trackers like the Xiaomi Mi Band 5 and the Samsung Galaxy Fit 2.

To turn it on, you will need to connect it to a charger first because there is no dedicated power button on the device. The magnetic charger makes things simpler and less difficult to do. In my opinion, it would have been excellent if considering having a crown button as it powers a watch with an appealing design and easy functioning.

Display-wise, the Uwatch 3s has a 1.3-inch Squared TFT LCD with a resolution of 240 × 240 pixels. This gives the watch a very clear image. Its touchscreen is employing 2.5D tempered glass with an anti-fingerprint treatment.

Instead of a completely round display, Umidigi is still utilising a square TFT panel inside a circular casing.

A lot of people earlier remarks about Uwatch 2s for not giving a totally round display, however, they didn’t consider this. In my opinion, this looks rather horrible, but what more could we expect from a cheap wristwatch.

Icy white, rose gold, space grey, and titanium grey are the four colour options that are available to you to pick from.

The overall design and presentation have not undergone any significant changes from the previous version. When compared to its predecessor, it provides you with the same appearance and display but has a slightly higher level of build quality.

Tracking your fitness, wellness, and activities with the Umidigi Uwatch 3S

Monitoring of the SpO2

A new feature that has been added to Uwatch 3s is the SpO2 blood oxygen monitoring.

On the rear of the watch is where its sensors are located so that it can monitor the oxygen levels in your blood and provide you with an estimate of how efficiently your body is taking in oxygen.

In comparison to a genuine SpO2 tracker, it displayed a discrepancy of one per cent. And within this pricing range, that constitutes a reasonable margin of error.

With this precision, it is particularly advantageous for persons with high-intensity job schedules. In addition, elderly folks are able to monitor their own oxygen levels while they are on the go.

The Sporting Mode

The Umidigi Uwatch 3S is equipped with a total of 14 distinct sports modes, some of which are as follows: bicycling, badminton, soccer, treadmill, basketball, strolling, sprinting, exercise, climbing, skipping, training, dance, and yoga.

You are free to select a particular sport at any time and set your watch to keep track of the rest of the data in the backdrop. All of the sporting data that is tracked is synchronised with the official app, which is called Da Fit. In addition, you are able to achieve the goals that you have set for yourself.

Monitoring of Physical Efforts

Like any other wristwatch, the Umidigi Uwatch 3s can also track basic health statistics like steps, calories burnt, and distance travelled. But what about its reliability?

The precision of the miles and calorie monitoring seems to be completely satisfactory to me. The distance tracking, on the other hand, appears to be slightly inaccurate. There was a variation of 1.7 kilometres when compared to what was shown on Google Maps. This was merely the outcome of the first attempt; subsequent attempts showed results that were much closer.

Keeping an Eye on Your Heart Rate

The Uwatch 3S monitors your heart rate at all times of the day and night with its 24/7 heart monitoring feature.

It was astonishing to find such results on a low-cost wristwatch when compared with genuine medical equipment like Wellue’s O2 Ring. The O2 Ring was displaying 62 beats per minute, but the Uwatch 3S was only able to get 59 beats per minute. Wow, isn’t it shocking?

The precision of the heart rate reading is rather remarkable. No question, you can surely utilise this gadget for reference by activating real-time heart tracking.

Due to the fact that this is not medical equipment, it is strongly advised that you do not put all of your trust in it. Every watch ought to be considered a potential reference device for the purpose of health monitoring.

Sleep Tracking

With Sleep Tracking, you obtain insights into your sleep data. You may record information about your REM (rapid eye movement), active time, light sleep, and deep sleep cycles by pairing it with your phone and using the DaFit app.

All of this information is then saved in an orderly fashion, making it possible for you to quickly retrieve it by the day, the week, or the month.

Let’s take a more in-depth look at what this data represents, shall we?

  • REM stands for “rapid eye movement,” which refers to the rapid movement of your eyes when you are sleeping.
  • Awake Time is a feature that monitors however many hours you spent awake in comparison to the total number of hours you spent sleeping.
  • Light Sleep is a type of sleep that counts the number of hours you slept but does not make you feel as though you are asleep.
  • Tracks the hours of your deepest sleep, during which your body moves less and your brain is less active.

Monitoring the Health of Women

The female health tracker that is included with the Uwatch 3s is commonly referred to as a period tracker. It gives you the ability to keep track of your periods and notifies you of the upcoming menstrual cycle as well as the ovulation phase. In general, a useful function for a woman to have in order to better understand her own health.

Features and functionalities of the Umidigi Uwatch 3S

The forecast for the weather

The Umidigi Uwatch 3S is equipped with a weather checker, which not only informs you about the state of the atmosphere but also enables you to make appropriate preparations before venturing outside. It is necessary for you to use your smartphone in order to retrieve weather information and sync it to this watch. Because of this, you will feel as though you are wearing a real smartwatch on your wrist.


Along the same lines as smartphones, smartwatches provide their users with a variety of helpful applications that can improve their day-to-day lives. In a similar vein, the Umidigi Uwatch 3s provides its users with some of the engaging tools that are described below:

  • The in-built three-axis sophisticated electronic compass will point you in the right direction, allowing you to take advantage of this feature’s full potential.

Notifications of Messages and Calls, in addition to Reminders

Receiving alerts of incoming calls and messages on one’s wrist may be rather convenient because it cuts down on the amount of time spent using one’s phone. For instance, if you have a hectic work schedule, rather than taking your phone out of your pocket to check for unread alerts, you may swipe the screen on your watch to get a brief look at them instead.

You are able to maintain awareness of who is phoning or messaging you by using Uwatch 3S. Additionally, these alerts contain status updates from platforms such as WhatsApp, Twitter, and Instagram, among others.

In addition to that, there is a function that is known as the Sedentary Reminder. If you lead a sedentary lifestyle, this function will come in very helpful for you. People who do not like to mingle and who prefer to sit in one spot watching television or playing video games are more likely to have health problems such as high blood pressure, diabetes, anxiety, and other conditions.

In order to protect yourself from the negative effects of leading a sedentary lifestyle, the Sedentary Reminder app will prompt you at the appropriate times to get up and engage in some form of physical exercises, such as walking.


This wristwatch has a waterproof rating of 5 ATM, which allows it to withstand depths of up to 50 metres for a period of 10 minutes. This enables it to endure water in the form of splashes and showers, making it perfect for swimming. Keep in mind that you should not use Uwatch 3s for any water activities, including diving in pools or the ocean.

Umidigi Uwatch 3S App

The DaFit app is what the Umidigi Uwatch 3S utilises in order to sync with your smartphone. The application may be downloaded for use on devices running either Android or iOS. You will be able to use the in-app functions of your Uwatch 3S once you have paired the two devices.

By pairing, you can:

  • Establish Objectives for Yourself, and Work Towards Achieving Them.
  • Retrieve the data for a specific time period using manual labour.
  • Keep an eye on your quality of sleep and chart it.
  • You may notify yourself of incoming calls by vibrating your watch.
  • Format the time in a different way.
  • Enable DND mode.
  • Monitoring of your heart rate should be enabled to be continuous.
  • Alter the weather units as necessary.
  • Modify Your Language.
  • You may personalise a variety of watch faces.

Note: It is always best to sync all of the watch data once in a while since it keeps you from losing crucial health and fitness data in the future. Syncing the watch data may be done by connecting the watch to a computer and following the on-screen instructions.

The lifespan of the Battery in the Umidigi Uwatch 3S

The fact that this watch is equipped with a 280 mAh battery means that it can keep working even after being turned off for several days. Umidigi says that its device has a battery life that may last for an average of 15 days when used normally. That is completely accurate; on a single charge, it was effective for a period of up to twelve days.

According to my hypotheses, if we cut down on needless contacts with the watch, then we might be able to get it to 14 or 15 days. The magnetic plug-and-play charging method is supported by the Uwatch 3S, and it takes around two hours to completely charge.

In general, you can use the device for a week without a single charge, which is sufficient for my needs.
