Although at first glance it seems that these are two completely different devices when on Haylou LS01 a Mi Band 4 we will look in more detail, we will find a lot in common.
Approximately the same price category can cause a dilemma for potential buyers, so we decided to compare the two products.

Design
Although appearance and design is an explicitly subjective matter, a few points can also be relied on in this category. First of all, we must write that the Mi Band 4 is smaller and lighter and for this reason it is also more comfortable to wear.
However, we must also include the display in this category, because it largely forms the design of the entire device. In the Haylou LS01, the display has a square shape and a diagonal larger by more than 0,3 inches. Its larger area displays more data.
Although the AMOLED technology of the Mi Band 4 is more efficient in color, we still find a larger display more advantageous. The Haylou LS01 has the look of a real watch, while the Mi Band 4 looks more like a bracelet.
In this category we give thumbs up for Haylou LS01.
Sensors and activity monitoring
We do not find much information about the complete structure and parameters of the sensors in the Haylou LS01, but they can still do more than the Mi Band 4. Both devices have a heart rate sensor and both have a continuous 24-hour monitoring function. Both monitor sleep and the number of steps per day.
None of the watches have a built-in GPS module, so positioning only works after synchronization with the phone.
Haylou watches have preset up to 9 sports activitiesthat they can monitor. It is Outdoor Running, Treadmill Running, Cycling, Spinning, Walking, Fitness, Hiking, Climbing and Yoga.
Mi Band 4 monitors 6 sports activitieswhich include Outdoor Running, Treadmill Running, Cycling, Walking, Fitness, Swimming.
We are announcing a draw in this category. Although Mi Band 4 monitors three activities less, they compensate with a swimming monitor. In addition, both devices can handle the monitor of basic activities in the same way.
Connectivity and durability
Because Mi Band 4 can monitor swimming, they must be waterproof. They are certified by the standard 5 ATM for immersion to a depth of 50 m below the surface. Haylou watches have increased water resistance certificate IP68, can handle rain and running water, but they are not suitable for swimming or diving.
Wireless interface Bluetooth 5.0 is more energy efficient and the connection is more stable in this version. They are equipped with Mi Band 4. Haylou LS01 have a version Bluetooth 4.2.
In terms of connectivity and resilience, the Mi Band 4 are better and win in this category.
Additional features
Both devices have all the functions of a standard watch, such as time display in 24-hour mode, timer, stopwatch and alarm clock. In addition, they display events from a paired smartphone.
Both will notify you of an incoming call, a received SMS message and display notifications from user-set applications.
With both devices, you can control the basic functions of your smartphone's music player while listening to music. In addition, the Mi Band 4 has a Weather application, while Haylou has a camera remote control function.
There is again a draw in this category.
Battery and endurance
Although the Haylou LS01 watch has a larger battery capacity, up to 210 mAh, it also has higher energy requirements thanks to the larger display. The manufacturer states the endurance per charge on 14 days. Of course, this information may vary depending on the method and intensity of use.
The Mi Band 4 has a manufacturer-specified endurance of up to 20 days at a battery capacity of 135 mAh. Here, too, the overall endurance may be different due to use.
Mi Band 4 seems to be better in this category.
Price

Conclusion
The final decision is, as always, up to you. Both devices have many similar functions and they can really do enough. We would choose the Mi Band 4. This is mainly due to better carrying capacity, water resistance, longer battery life, but also lower price.
On the other hand, the advantage of the Haylou LS01 is the large display, the design of a full-fledged watch and the unbeatable price in this category.
