There are various features to monitor when buying a lemfo smartwatch. First of all, I would be cautious about the warranty (we always talk about imported products that could be subject to different warranty policies, therefore offer different technical support from the European or Italian one).

Then evaluate all those features you would focus on by purchasing a unique brand product: the shape of the dial (circular or square), size/weight ratio, type of display, SIM support, operating system, and so on. For more details, keep reading. Everything is explained below.

Here we had listed out the best lemfo smartwatches that are present below.

Buying Guide to Select the Best Lemfo Smartwatches

Dimensions, Weight, and Shape

The face of a smartwatch can be of various sizes and can be square or circular. The choice, in this case, is purely subjective and has few repercussions on the use of the device.

But usually, circular displays are more elegant while square displays favor usability (as they allow you to view a few more elements on the screen).

Then take into consideration the quality of the construction materials of the watch, its strap, and, if you deem it necessary for your use, check if the device offers resistance to water and dust.

Mind you that the waterproofing is not infinite: there are a maximum number of meters of water and minutes that the smartwatch can withstand diving. Once these limits are exceeded, the resistance of the device to liquid is no longer guaranteed.


This choice is quite delicate and depends once again on the needs and areas of use of the smartwatch. If you intend to use it only for fitness, a small display may suffice, while in the case of applications in combination with the smartphone.

The displays of at least 1.2 inches are ideal. Smartwatch manufacturers equip these devices with various types of shows: most of them are OLED or AMOLED, but many others use LCD.

The first type ensures long-lasting autonomy and proves to be very competitive in the rendering of blacks, always very faithful and profound. LCDs, on the other hand, are usually better in terms of viewing under sunlight.

There are also technology-based smartwatches on the market paper, with displays similar to those of ebook readers (which ensure a very high degree of battery autonomy and can be seen correctly in the sunlight). Still, in the current production of smartwatches made in China, there are not of this type. Needless to go further.

On the other hand, a feature that must also be taken into consideration in the context of Chinese smartwatches is support for the always-on mode.

The mode by which the smartwatch can always remain on in a manner that allows you to have the time and other contents (e.g., the counter with notifications to read) always displayed on the clock face without consuming much energy. In smartwatches that do not support always-on mode.

The displays light up only when the user moves his arm towards the face (thanks to the accelerometer inside the device) or when the screen is touched with a finger. Finally, evaluate the presence or absence of the light sensor.

Thanks to this sensor, the smartwatch can realize the brightness level of the surrounding environment and automatically set the brightness of the screen so that it is appropriate to the situation. For me, it represents a significant feature!

Components and Sensors

Before buying a smartwatch, be it Chinese or not, you need to analyze its technical specifications carefully. It is necessary to understand what type of sensors it includes and what kind of performance it can guarantee. Here are the components and sensors you need to focus your attention on the most.

  • Processor – is the “brain” of the smartwatch. Its power, which is expressed in Hz and can be divided between several cores, determines the speed with which the electronic watch manages to perform daily operations.
  • Ram – is the Memory where data of running processes and apps are temporarily hosted. The more there is (therefore, the more GB of RAM there are) and the faster the clock is in the passage from one app to another.
  • Internal Memory – The internal Memory of smartwatches is used to store operating system data, apps, and, in many cases, to save music to listen to via wireless headphones (leaving the smartphone at home). Some smartwatch models also offer a microSD slot through which to expand the Memory available for music or other data.
  • Speaker and Microphone – the speaker is simply the speaker through which a smartwatch can make sounds. The Microphone is used to answer calls directly from the watch and to interact with the smartphone’s voice assistant. If you need a smartwatch that allows you to answer calls, buy one with a speaker and Microphone.
  • Gps – if present, this component allows you to track the distances covered in your sports activities without taking your smartphone with you. Using GPS, however, know that it severely affects battery autonomy.
  • Heart Rate Sensor – smartwatches equipped with this sensor allow you to monitor your heart rate.
  • Nfc – this is the chip that allows you to make micro-payments and communicate instantly with other devices that support NFC technology.

Connection and Autonomy

Usually, these products work using the Bluetooth and WiFi connection. Thanks to these types of relationships, they connect to the Internet to allow the user to browse or download mail or, again, read and envy messages on WhatsApp or other similar apps.

Access to apps, depending on the type of smartwatch purchased, can be tied to the smartphone or be independent. Some smartwatch models also have a SIM installation slot that allows you to access the Internet and make calls in the absence of the mobile phone.

Battery autonomy is almost always between 1-2 days, but of course, it is a parameter that is subject to a series of variations and usage habits. However, I advise you not to drop below 100 milliamperes (mAh), which is a unit of measure in which the battery capacity is expressed.

Operating System and Compatibility

Chinese smartwatches can be equipped with proprietary operating systems, with modified versions of Android for smartphones or with Android Wear, which is the version of Android designed specifically for wearable devices.

In all three cases, compatibility is guaranteed almost 100% with all smartphones equipped with Android 4.4 and later (so you can receive notifications from the phone and answer calls).

As for iOS, therefore iPhones, compatibility is almost always ensured with watches that have a proprietary operating system or Android Wear but with limitations with respect to the functions accessible on Android smartphones.

Another essential thing to note is that many smartwatches with a proprietary operating system do not interact directly with the apps installed on the smartphone (they only receive notifications from the latter) but include autonomous apps, which allow you to reply to messages,

Accessories and Customization

Many smartwatch users like to be able to change the strap. In many cases, they do it for a matter of fashion or aesthetic appearance, in others for more practical reasons.

The straps can wear out, or the standard one may not be suitable for certain types of actions, such as going underwater because it is not waterproof.

In the long run, we get tired of always having the same strap, and it is essential to be able to change it with a completely different style, possibly without spending a fortune.

Customization is also essential at the software level, so before buying a smartwatch, make sure that this allows you to change the appearance of the dial according to the user’s tastes.

Smartwatch, Sportwatch or Smartband?

Before purchasing a smartwatch, you must have this distinction clear. Are you interested in a device that helps you manage your fitness better, or are you a sedentary person who intends to have a tool that interfaces differently with your smartphone?

The traditional smartwatch helps you above all to view and respond to emails and messages, manage calls, and social networks directly from the wrist if you need a device dedicated to sporting activities.

I recommend you opt for a sportswatch, that is, a smartwatch with functions and sensors dedicated exclusively to sport, or a smart band, that is, a fitness bracelet with intelligent features that allows you to keep track of physical activities by offering statistics on the steps taken in a day, on the distance traveled, the calories burned and the heart rate, etc.

There are very cheap fitness bracelets, others more expensive with advanced features such as the heartbeat detector. The latter, above all, could be more precise, an element that you must keep insignificant consideration because the lack of precision could make the training not so useful.

Then, fitness bracelets must be comfortable, because otherwise, they disturb during physical activity. Fitness bracelets usually outperform smartwatches in terms of autonomy but are also heavier and bulkier to use. But there are also those devices that do both well, blurring the boundary between the two categories.
