Realme TechLife Watch S100 review: A true budget smartwatch with long battery life


Realme recently launched a new smartwatch under its TechLife brand. The smartwatch, dubbed as the Realme Watch S100, features a 1.69-inch touchscreen color display, up to 12 days of battery life, a SpO2 sensor, and a skin temperature sensor among other things. It lets you remotely snap images using your smartphone’s camera at a pocket-friendly price of Rs 2,500.

With its Realme Watch S100, Realme wants to make a smartwatch available to everyone, for almost everyone. Its feature-rich design along with its price enables it to do so, at least on paper. The real question is whether it has been able to deliver on those promises efficiently or not?

I have been using the Realme Techlife Watch S100 for almost a month and I believe it is capable of achieving something, but not without its own set of challenges. For example, the display is bright and responsive but it fails under the sun. We’ll talk about other features of this entry-level smartwatch in a detailed review below. So keep reading.

performance and design

The design of the Realme Techlife Watch S100 is very similar to the Realme Watch 2. It includes a large 1.69-inch color touchscreen display that offers a resolution of 240×240 pixels. The squarish dial is surrounded by thin bezels and has a metallic finish. This dial is attached to a silicone strap that ships inside the box. The quality is average, but you can change that at any time, so you can have plenty of options to choose from. On the side of the watch sits the power button, which controls power and standby. It also takes you to or away from the app menu.

The smartwatch delivers impeccable clarity. Touchscreen works fine. But when you take the smartwatch in the sun, the brightness decreases. To add to this, there’s no auto-brightness adjustment option, which means you’ll have to increase the brightness manually when you step outside.

One thing that I like about the Realme Techlife Watch S100 is that the company has reduced the bezels a bit compared to the Realme Watch 2, which gives it a better screen area.

The touchscreen display of the smartwatch offers a seamless experience and makes it very easy and convenient for you to move from one screen to another. The large dial clearly shows notifications in large font and it lets you read messages and emails with ease.

Overall, the smartwatch is exceptionally comfortable to wear all day long and doesn’t feel so heavy at any point. However, the premium feel is missing. Obviously, you cannot expect much from a smartwatch coming in this price segment.

As for performance, the Realme Techlife Watch S100 smartwatch is packed with features. It comes with several health-tracking features which include a heart rate monitor, a sleep monitor, a SpO2 level monitor, an accelerometer, a pedometer and a body temperature sensor. While the heart rate sensor and skin temperature sensor measure your vital organs accurately and are fairly close to a standard temperature gun, the pedometer often misses the mark. Step count accuracy can vary from 500 to 800 steps per 10,000 steps.

The smartwatch also has various sports modes to keep track of your workouts, including outdoor runs, cycling, badminton, and yoga. These modes track your workouts very accurately. The Realme Techlife Watch S100 comes with Bluetooth 5.1 connectivity, which it uses to connect to your smartphone to track your runs, walks or cycle rides using the phone’s GPS.

Apart from the health tracking features, the Realme Techlife Watch S100 also has over 110 watch faces. You can easily replace them with the Realme Fit app, which is available for download on Android and iOS platforms. This app provides you with a detailed summary of the vitals you have measured, including sleep tracking data, heart rate measurements, SpO2 and skin temperature data.

Setting up the Realme TechLife Watch S100 is extremely frustrating, and it took me four to five attempts to pair the watch with the app. I also faced difficulty while setting up the smartwatch through the Realme Fit app as the QR code was not scannable. I had to do it manually.

Additional clock features include a music controller that can be used to play, pause, and shuffle tracks, a weather app, a Find My Phone feature, alerts for incoming calls and notifications, a stopwatch, and others. An alarm among things.


One of the most notable features of the Realme Techlife Watch S100 is its battery. It has a 260mAh battery, which Realme says can last up to 12 days on a single charge, but in my experience, it totally depends on your usage. I constantly used the SpO2, heart rate and heart rate monitoring, and sleep tracking features, and during my time with the watch, it gave me a run time of about seven to eight days.

The smartwatch features a magnetic charging dock that can be plugged into a PC or laptop USB port or used as a power bank in low-power mode. It took me about 2 hours to fully charge the watch from 0 to 100.


Overall, the Realme TechLife Watch S100 is a decent entry-level offering at a price of Rs 2,499. Its build quality is good and it is also quite lightweight. Its user interface is also quite smooth. One of the USPs of this smartwatch is the Realme Fit app and battery. In my opinion, the Realme Techlife Watch S100 can be a good option if you are looking to buy an entry-level feature-packed smartwatch.

But there are some areas that could use some updates, mainly including brightness auto-tuning and greater accuracy of health tracking features. That said, the Realme TechLife Watch S100 does make for an interesting proposition for budget buyers or those who are just starting their fitness journey.
