LEMFO S30 Review: Smartwatch with Immunity Function

LEMFO recently introduced a new low-cost fitness smartwatch called the LEMFO S30 and let’s see what the new model is capable of.

In this review, you will find out what are the main changes received by the updated version of the S30, when compared with the LEMFO S20. In addition, I will share with you my observations on wearing comfort, pros, and cons.

Many users don’t need a full-fledged smartwatch with a lot of useless features. Since the main problem with real smartwatches, when compared to a fitness watch, is battery life. Therefore, most manufacturers have switched their interest to budget fitness watches, such as the new S30 model.

A little about the price, the new generation of fitness watches LEMFO S30 has received almost the same price as its predecessors or its main competitors from Microwear. Now the price of the watch is about $22. But do not forget about 11.11, where you can buy gadgets at the lowest possible prices.


I will also say a few words about the technical component. The watch uses a 1.3-inch color screen, HS6620 processor, full protection against water, and many features that will monitor your health.

Therefore, I propose to start a full and in-depth review from the box and find out what equipment will be in an inexpensive smartwatch.

Unboxing and packaging

The smartwatch comes in a small white rectangular box. On the front, you can see a sketch of the watch and the name of the company and model. I want to note that the appearance of the box is completely the same as on the previous generation LEMFO S20.

Inside the box, I found a standard list of components – this is an instruction manual, the smartwatch itself, and a two-pin charging cable.

In general, the equipment is very simple, but given its cost, it makes no sense to expect more. But now let’s talk about the build quality and appearance.

Design, build quality and materials

LEMFO S30 is a modern smartwatch with a round dial. The manufacturer offers several options in different colors – black, gray, and gold. There are also various strap options ranging from silicone to metal.

The appearance of the new fitness watch from the LEMFO brand turned out to be very attractive. In design, they strongly resemble models such as NO.1 DT88 Pro, LEMFO SG2, and other models.

The watch case is made of a metal alloy, but the backside is made of glossy plastic. In addition, the front part has a protected glass with 2.5D rounding. In general, the build quality is at a high level, the watch is made monolithic and I have no strong remarks about its performance.

The LEMFO S30 fits perfectly on the wrist and it was a pleasure to wear it. The device weighs about 45 grams, and its dimensions are 43.5 x 48.5 x 12.8 mm. Even sleeping in them was not so bad, considering that this is not a fitness bracelet, but still a full-fledged smartwatch.

The face of the fitness watch received a 1.3-inch IPS touchscreen color screen with a resolution of 240 x 240 pixels. In general, the screen quality is not bad and you should not expect more from a budget watch. But I note that the frames around the screen are not very minimal, but the screen brightness is at a good level.

Also on the right side, there is a mechanical power button and its location is not in the central part, but slightly higher. For comfort, this is a convenient solution, the index finger fits perfectly on this button. It is designed to turn on and back.

The reverse side of the smartwatch has attractive glossy plastic. At first glance, you might think that the watch has wireless charging, but in reality, it is not. In the central part, there is a heart rate sensor, and just above there are two magnetic contacts for charging.

An important feature is a protection against water under the IP68 standard. It is complete protection against water and you can easily wet your watch, shower, or swim in the pool.

As I said, the strap on the LEMFO S30 has several manufacturing options – silicone and metal. A corresponding strap color is supplied for each case color. At the same time, the strap width is 20 mm and it is removable, that is, you can easily change it to any other option, if necessary.

Okay, I figured out the appearance, now let’s talk about the main functions and check how they work in real life.

Functions, features, and application

The home screen of the LEMFO S30 smartwatch only offers three different watch faces. The number of watch faces does not stop there and you can install many more watch faces in the application. But more on that later.

The functionality is very simple and resembles most fitness watches like other competitors. For example, swipe down to get to the quick settings menu. In this menu, you can see the QR code for downloading the application, find out information about the watch, find a smartphone, the battery level, and set the screen brightness level.

Flicking to the left brings up some useful widgets. Here you can find widgets such as daily activity, sleep analysis, health widgets, sports modes, immunity, and body temperature widgets.

The watch uses about 11 different sport modes, which is not so bad. But I especially liked the presence of health tracking. That is, you will be able to analyze your heart rate, blood pressure, pulse, EKG, and even blood oxygen levels. In addition, I was surprised by a new function – this is an indicator of immunity. But the body temperature, I have already met on many other models of smartwatches.

Swiping to the right of the home screen takes you to the main menu. There is a list of functions such as stopwatch, timer, find phone, alarm, and others.

I also want to tell you a little about the mobile application, which is called WearFit 2.0. The application is available for both Android and iOS operating systems.

The watch is connected thanks to the wireless Bluetooth 4.0 connection. The application menu contains typical functions, such as setting up notifications, installing additional watch faces, and other features. Immediately, I note that the number of watch faces is not so many, only 5 different types.

Battery and run time

The LEMFO S30 smartwatch received a 240 mAh battery. Considering that the screen resolution is not the highest, the battery life will be good.

The manufacturer promises about 10 days of work, but in fact, I think that the watch will be able to work for about one week. At the same time, the Bluetooth connection will always be active and you will often receive notifications.

A full charge via the two-pin cable will take you up to 1.5 hours of your time.

Conclusion, reviews, pros, and cons

The LEMFO S30 is a decent smart fitness watch that I have been able to test. The main feature of the watch is its functionality with a large number of different features, including tracking your health.

The design turned out to be very minimalistic, but the manufacturer offers a large number of different colors. I also liked the build quality and the materials used.

In general, given its low cost, smartwatches from LEMFO are definitely worth their attention. But let’s talk a little more about the price.

Low price and where to buy cheap?

Currently, the cost of the LEMFO S30 fitness watch does not exceed the price tag of $22.74 with a 53% discount.

But I also want to remind you of the upcoming date 11.11, where you can purchase any product from China with a good discount.
