So I got the Xiaomi Mi Body Composition Scale 2 along with the Mi Band 4 (made a review for it here btw), in my quest to have more metrics to analyze my health and overall fitness state. And how it progresses.

Now, I’m not a fitness guy or anything. Just trying to make some adjustments as work takes a toll on the body and you can easily wind up… well… not so fit. Along with improving my lifestyle, having something to monitor progress feels like the right thing to do.

First of all, a disclaimer: this is not a magic device. It does have error margins, especially on the body composition statistics side. But still, for monitoring progress, it’s a great tool. (i mean, decreasing body fat by 5%, is still progress even if the readings are off by a couple of percent)

As far as I can tell, as a weight scale, it works great! Checked it with 3 other scales (electronic and classical) and this seems in line with everything.

Please note that this is the latest Mi Scale model, and if you want the latest and greatest, be wary of the product code below so you won’t accidentally buy the last year’s model. (the old one has Bluetooth 4 only and less body composition statistics)

My experience with the Mi Body Composition scale

First of all, it looks great! It fits well in any modern bathroom. And as a plus, the tempered glass makes it so easy to clean that it always looks brand new.

The weight is shown with a discreet LED display that looks hidden. You can’t even tell anything will appear on it until you start using it. And when you do, the white numbers add to the modern feel of the device.

I paired it with the Mi Fit app – it takes like… 30 seconds maximum, as the display only shows your weight. The other statistics can be found in the app. And they instantly sync when you get up on the scale with your smartphone. Pretty neat.

How does it work? It uses a bio-impedance analysis to estimate body metrics. Basically it sends a small electrical signal through your feet, and the time to complete a circuit is used to estimate your body’s composition of fat, muscle, and bone.

As I did not have my body fat or bone mass measured by a doctor or using some professional device, I cannot say how on point the scale is. But, I can aim to decrease the figure. So that’s that.

In the month I used it, I measured myself daily, and I didn’t have any issues with it so far. So I’ll just carry on and don’t forget! Exercise and diet make a difference. These are just gadgets.

Build quality


For about 38$, this is a great weight scale. Plus, it’s smart! Having the data recorded in an app for easy monitoring and the other body metrics are just a great bonus! It looks and feels like a great product. Would recommend to anyone looking for a smart scale.
And the fact that it has Bluetooth 5, means that the batteries will not die too soon.
