Fitness trackers are becoming more and more popular because of the growing awareness for a healthy lifestyle — and then again there's the summer coming. If you are still looking for a trusty fitness companion, we suggest taking a look at the new Lenovo Cardio Plus HX03W — a top affordable smartband that will surely be very helpful in achieving your fitness goals.

At present, you will need to pay $21.99 for the Mi Band 2, but the Cardio Plus HX03W can be yours for just $19.99. But despite the smaller price tag, the Lenovo Cardio Plus HX03W can also compete with the Xiaomi Mi Band 2 when it comes to design and functionality. Let's dive into the details.

The Lenovo Cardio Plus HX03W is one of the most stylish fitness trackers we've laid our hands on. It comes with a  0.96'' OLED screen with a small touch button, featuring the popular bezel-less design. By the way, the rectangle display is about twice as big as that of Xiaomi Mi Band 2 - 0.42 inch — thus, icons, notifications and messages are also larger, so it is easier for you to look at them when you raise your wrist.

In contrast, the Mi Band 2, which was released in 2016, has a much smaller display but a bigger touch button. Although it did follow the trends in its time, today the design may come off as a bit old-fashioned.

The materials used to make the bands are also different. The Cardio Plus uses a TPE band, which is considered better for everyday use than the silicone band on the Mi Band 2. Although silicone bands are anti-shock and waterproof, you may find that they become sticky and dirty overtime. However, TPE bands are different: they are oil-resistant, wear-resistant, anti-mildew and anti-bacterial, which allows them to remain clean and not cause any skin irritations.

Features and performance

The Lenovo Cardio Plus HX03W has all the features of a basic smartband, including notifications, pedometer, activity tracker, sleep monitor, heart rate measurement and so on. Pretty much the same as on the MI Band — but take a closer look and you will notice three distinct differences between the two smart fitness bands.

● Bluetooth version

Bluetooth version plays an important role in data transfer and battery life of a smart band. The Xiaomi Mi Band 2 features Bluetooth 4.0 while the Lenovo Cardio Plus HX03W features Bluetooth 4.2 to connect to your smartphone. Bluetooth 4.2 uses less power and transfers data 2.5 times faster than earlier versions.

So, while some Mi Band 2 users get impatient when waiting for the completion of data synchronization, whereas, with Cardio Plus HX03W smartband, you will get your info almost instantly.

● IP rating

The IP rating of Cardio Plus HX03W is IP68, and that of Mi Band 2 is IP67. The waterproof level of Cardio Plus smartband is higher  — more specifically, you can wear the Mi Band 2 when washing hands and taking a shower; but the  Cardio Plus HX03W will remain intact when you are bathing or swimming — it can even be taken up to 1.5m underwater.

With summer right around the corner, "waterproofness" is an important factor to consider.

● OS language

The Xiaomi Mi Band 2 only supports Chinese and English, which is quite limited. The Lenovo Cardio Plus HX03W breaks the language barriers for worldwide mobile phone users providing 12 language options including Traditional Chinese, Simplified Chinese, Japanese, English, Russian, French, Italian, Spanish, German, Polish, Norwegian, and Danish.

Language-wise, the Cardio Plus will be a much more convenient option for those who do not have a strong knowledge of English: for instance, kids and seniors. The multilingualism of the smart band also makes it possible for the whole family to use same brand fitness bands and easily share data and fitness goals.

Charging & battery


Fast charging is critical for most mobile devices. The Lenovo Cardio Plus HX03W has a built-in 85mAh lithium-ion battery lasting for up to 7 days with heart rate monitor turned on and it takes only 1 hour to fully charge it. The Xiaomi Mi Band 2, on the other hand, comes with a  70mAh lithium-ion battery lasting for up to 15 - 20 days — but you will need 3 whole hours to fully charge it, which is quite a lot for such a small device.

Fitness trackers are designed to be by your side day and night, so you truly appreciate the fast charging option.

Furthermore, after taking off the band, you can directly plug the HX03W into a USB interface. In comparison, you must use the specially designed charger base to supply power for the Mi Band 2.

Thus, if you are constantly on the go, and need measure your heart rate throughout 24 hours, the Lenovo Cardio Plus HX03W smart fitness tracker will be a better choice.

Now, let's summarize: take a quick look at the main features of the Xiaomi Mi Band 2 side by side to with the  Lenovo Cardio Plus HX03.

Which one to choose?

As one of the latest budget fitness trackers, the Lenovo Cardio Plus HX03W comes with all the necessary fitness tracking features and challenges the dominant position of the Xiaomi Mi Band 2. The Cardio Plus HX03W smart fitness tracker has a larger display, 2h shorter charging time, a newer Bluetooth version, higher IP rating, and more language options. Pairing all of that extra functionality with a price tag that is $2 lower than that of the Mi Band 2 (now on promotion), the Cardio Plus HX03W seems to come out on top — at least until Xiaomi's next smartband release.
