The Xiaomi Mi Band 4 is one of the best options to record our physical activity, taking into account its price. That does not mean that it is the best option in the market since it has some technological lack that certainly makes it inaccurate at some times, according to many users of the bracelet in the official Xiaomi forums.
It is difficult to offer more for less, and the Mi Band 4 is an example of an economical product that for about 35 euros allows the user to have a complete wearable, although with some insurmountable technical deficiencies for the most demanding users and who are part of the worst of this bracelet.
Problems with running
Xiaomi forums are coming from people who love running, who have problems with the bracelet, more specifically with the measurement that the bracelet makes of its routes. Some people indicate that on distances of 9 kilometers the bracelet records distances of 14 kilometers or 3 kilometers, that is, that the registration can vary upwards or downwards, which causes the frustration of many owners of the bracelet who use it to leave to run.
The problem is that the Mi Band 4 does not have a dedicated GPS, so, although it is very convenient to go jogging with her leaving the mobile at home, the measurement will not be accurate since you cannot take control of the satellite route through of the mobile, so that the results can be properly dumped in the Mi Fit app.

The only guide that the bracelet has when it cannot connect to the GPS of the mobile is to register steps or strides from the internal accelerometer. Although they have been designed to detect the movement pattern, they have a margin of error that can sometimes represent a wide margin of error with respect to the actual distance traveled.
The solution in the Mi Band 5?
Therefore and in case Xiaomi is thinking of evolving the product to reach more demanding users, the Mi Band 5 should have at least one option with GPS, to meet the needs of a large number of runners. In the meantime, if you have the Mi Band 4 you go out for a run, you will have to carry the cell phone on top so that the recorded distance is as accurate as possible. Some user indicates that by modifying the height parameters, the bracelet will identify a different pattern in the stride. In that case, it is playing with it until we find the formula for our way of running, although it is a somewhat cumbersome solution.
