Without needing more details, let’s dive into this review.

Design And Build Quality:

Many smartwatches that work with Android bother me about the large size and weight, although it makes sense for the hardware it comes with, but, LEMFO LEM15 was not because its medium in size with an unexpected weight of no more than 75 grams, and as usual, LEMFO presents us with a stylish smartwatch and beautiful and suitable for sports or events, it has a circular design, a 1.6-inch screen, and a strong black body made of ceramic and plastic with high manufacturing quality so it will not be easy to scratch.


The main camera is on the top, and on the right side, there are two buttons power/back, the second camera is in the middle between the two buttons. and on the other side, there is a Nano-SIM slot.

On the edge of the watch, there is a speaker and microphone which does not have the best sound quality but for a smartwatch it’s fine. On the back are the usual charging pins and a heart rate sensor.


Coming to the strap, it’s made of silicone which makes it lightweight and comfortable on your wrist for long-term use. You can use any strap of 22 mm because it’s removable, but it is available in black only and you can buy another in different colors or in metal or leather separately.



With IP67 waterproof in LEMFO LEM15 Smartwatch, It means you can wear it while washing hands or on rainy days, although the watch is not approved for swimming but is good for wearing for activities, so, I do not recommend swimming or exposing it to hot water or saltwater or press the buttons underwater to avoid any harm Long or short term. It’s preferable to dry the watch after immersing it in water and before operating it so that it stays with you for as long as possible.

Display Screen:

I found the screen of LEMFO LEM15 excellent with great color contrast even under the sun, and this is what we find in most IPS screens. It’s circular with a size of 1.6 inches, and a ratio of 85% from the screen to the body, the resolution is 400 * 400 pixels, with a pixel density of 354 pixels per inch, and this is what makes the contrast and brightness are good outside or under any condition, and it has a good touch response.


For Android smartwatches, you need the largest screen possible, but if it’s too big, it can make you struggle in your hand, and that’s what I like about the LEMFO LEM15, everything is balanced. In addition to all this, the watch does not support the always-on screen, but it does support the wake-up feature, all you have to activate it from the settings if it’s not activated to be able to turn on the screen automatically whenever you raise your wrist.

LEMFO LEM15 Performance:

LEMFO LEM15 provides overall high and smooth performance without any problems with the speed of opening apps or browsing the smartwatch, thanks to the powerful Mediatek Helio P22 ( MT6762) Octa-core chip that works at up to 1.8 GHz with a 16nm manufacturing process and is based on Cortex-A53 architecture. If you told me the processor is old, of course, it is, but we are talking about a smartwatch here, and it provides very good performance in games and applications, and there are smartphones that still use this processor, the most famous of which is Elephone E10 Pro, Samsung Galaxy A10s, Oppo A1k. So, This CPU is suitable for multitasking and running applications that need a powerful processor and this is done with the help of 4GB of RAM DDR3, Which is more than enough for a mid-range smartphone, not to mention a smartwatch.


If you are wondering if you can play games? Of course, you can and believe me even PUBG and COD but the minimum settings, plus the experience of playing car games was great, although the biggest obstacle is the small screen and there are some games and applications that may not work because they are not equipped with such a device.

In terms of storage, there is 128 GB Yes, it is a very large space that can be used to download apps, music, movies, or anything you want. You just have to make sure that it is compatible with the formats supported by the watch from the specification table below.


Also, has Bluetooth 5 technology support Bluetooth calls and makes the watch low power consumption and a more stable connection. This version is compatible with Android 6.0 and later or iOS 11.0 and above so that the connection is through the Wiiwatch 2 app.

Writing on screen:

Although typing on the screen can be a bit tricky because the letters are very small and you may find yourself typing the same letter twice on multiple occasions. So there are some limitations due to the screen size, but you can get used to it.

Watch videos:

You can watch video content on this smartwatch through YouTube, Netflix, or on any platform you want, but don’t expect a full experience because the small screen and even the resolution won’t allow it, not to mention that most of the apps aren’t really designed for round screens. However, you have the possibility to turn the screen on each regular square, and this will be explained below

How To Use LEMFO LEM15:

The LEMFO LEM15 Smartwatch runs a very easy-to-use platform, and the touchscreen navigation is responsive.

  • By swiping from the top of the main screen, you will get two quick settings menus, and to change between them all you have to do is swipe from the right. The first shows the time, data, Bluetooth, and Battery percentage. the second is quick settings such as brightness, data, Bluetooth, Wi-Fi, flight mode, Do Not Disturb, GPS.
  • If you swipe from the right – there will be the main menu of all LEM15 applications and swipe again from the right to access the sports modes.
  • If you swipe from the left – only notification messages will appear.
  • And as I said to switch the screen to the normal square shape all you have to do is press and hold the power button for 2-3 seconds to switch the watch to the square screen.


LEMFO LEM15 is a new smartwatch that runs on Android 10.7 that has been optimized for LEM15 with a good interface that is very easy to navigate and smooth, adding Ul icons for various interactive special effects, and adding a menu interface like Android Wear.

The system allows you to install almost any app and game from the Google Play Store, although some apps and games will not support the circular screen. As we said earlier, there is a solution to this problem. The LEMFO LEM15 comes with more than enough specifications for a smartwatch, so most likely you will not find any problems with the performance and smooth operation of applications.


All social media applications were fully functional such as Facebook, Instagram, Twitter, and especially WhatsApp because there is a SIM for making calls and I did not find anything hindering it except the keyboard, which may take some time for you to get used to if the LEM15 is the first smartwatch of this type that you buy.

Wiiwatch 2 App For LEMFO LEM15:

LEMFO LEM15 is compatible with the Wiiwatch 2 app for Android and iOS to help you set up and use your watch more efficiently via synchronization. You can take advantage of some features, stats, and functions without the need for any additional equipment, such as steps taken, hours of sleep, heart rate measurements are taken, all done by integrating watch data automatically on the home screen with the ability to view it on a daily or monthly basis. Also set exercise goals and encourage yourself to complete the amount of exercise each day with a simple and easy-to-understand operating interface with sections such as steps, distance, notifications, alarm, and more.

You can also set an alarm, change watch faces, or you can set a daily step goal and change your profile settings. Bear in mind that this is not medical equipment and for that reason, do not rely entirely on smartwatch data.

How To Pair The LEMFO LEM15 To A Smartphone:

It’s easy to connect the LEM15 Smartwatch to your phone. After installing the Wiiwatch 2 app and setting it up, all you have to do is log in and the phone will search and find the watch in seconds, and you must do that by searching for the Bluetooth and the watch through the app’s Bluetooth and not Via Bluetooth in the phone. When this is done, it will be connecting directly and without any complications.

Making Calls On LEM15:

Of course, you can make phone calls directly from the watch. We have a microphone and a speaker. Keep in mind that if you use this watch connected to your smartphone, you will not be able to make phone calls to it through the phone. But if you have a SIM card inside, you can make phone calls just as you would from a regular phone.


With nano SIM support, you can have an independent call, you can also send and receive messages directly from the smartwatch. Have a video call and its front camera.

Health And Fitness:

The LEMFO LEM15 is loaded with 9 sports modes, managing the heart sensors, blood oxygen, and Bluetooth connectivity. The 9 sports included: outdoor running, outdoor walking, indoor running, outdoor cycling, basketball, football, table tennis, badminton, and rope skipping.

Apart from the sports features, you can track your location thanks to the built-in GPS function and view your exercise path. In addition to real-time monitoring of your heart rate to check whether it is beating normally or not, sleep monitoring to measure your total light sleep, deep sleep, and waking time to provide you with an analysis of your sleep patterns Monitoring blood pressure and measuring blood oxygen levels in real time to improve the ability of the cardiovascular system to Prevent the low level of oxygen in the blood that causes discomfort to the person’s body.

Although it has a good sensor that is more accurate than other smartwatches, this does not mean that the measurements provided by this smartwatch are not completely accurate, most of them are highly unreliable as they are not a medical instrument, but it does make you fully aware Your health and physical performance.

Network & Connectivity:

One of the most important features of LEMFO LEM15 is the ability to connect to 4G LTE networks, so the ability to insert a SIM card works independently and this allows you to do many things without the need for your phone and access the Internet everywhere.

In addition, they have dual-band 2.4GHz-5GHz Wi-Fi and Bluetooth 5.0. This means that you can connect some Bluetooth headphones and then you can listen to music with headphones or make phone calls.


If you are using this watch with a SIM inside it means you can make calls and send/receive SMS even without using your phone as it is compatible with most frequencies, you can use LEM15 like any normal smartphone. And If you receive a notification, you can respond to that notification. However, if you are using this watch connected to your smartphone, you will be able to see the notification but will not be able to respond. You need to use LEMFO LEM15 as a phone to be able to respond to notifications.

What’s the difference between inserting a SIM card or not?

You can’t make phone calls without a SIM card, but you can surf the Internet and use apps after connecting to WIFI. After inserting the SIM card, you can make a phone call from the watch.

Dual Cameras In LEMFO LEM15:

The camera is an indispensable thing in such a smartwatch because it is closer to a smartphone, thus LEMFO LEM15 gives you a dual camera that you can use both cameras to record videos, take pictures or video calls, and pictures are taken better in bright light conditions.


The front camera is 2MP with autofocus that gives you high-quality photos and a reality that I didn’t find too bad for a smartwatch on your wrist and you can make video calls with acceptable quality and a fast face unlock.

On the side is the main 5MP for taking high-quality photos, and since it is on the side, it can take great pictures for shooting sharp angles, which cannot be taken with a regular camera.

LEMFO LEM15 Battery And Charging:

The battery in the LEMFO LEM15 has a capacity of 900 mAh, yes, it is large, and on top of that you will get a wireless power bank with another 900 mAh capacity, the battery remains acceptable and lasts as it gives you 1-3 days max. So you can finally spend a whole day and more on one charge, this may seem normal to you, but believe me, with such specifications it is difficult to achieve such a result.

However, it all depends on your usage of the watch as we know that Wi-Fi networks, GPS, and running high applications consume more power. About the charging time, from 0 to 100% usually takes no more than 3 hours with the use of magnetic charging.
