When it comes to choosing a smart band especially in the budget range, we have got quite a lot of options. The most popular Mi Band 2 and the comparatively new kid in town Lenovo HX03 Spectra are two best candidates for a comparison. On the outside, it may seem only changes in the display comparing both the budget smart fitness bands but when we look closer, there are much more differences when we are actually using both of them. Let’s get into the business by looking at the specifications for each band individually. And let’s also discuss the pro and cons of each band so that you can decide which one fits you more.
Mi Band 2 Features:
- 0.42-inch OLED display (Black & White)
- Optical heart rate sensor
- Sleep tracking
- IP67 Water resistance
- Battery life up to 20 days
- Weight: 7g
- Price: ₹ 1799
Lenovo HX03 Spectra Features:
- TFT Color display
- Heart rate sensor
- sleep tracking
- IP68 Water Resistant
- Battery life up to 10 days
- Weight: 20g
- Price: ₹ 2299
As you see in the above specifications, the display is the only considerable thing on paper which gets different on both devices. But is that it?.
The display is bigger and better in Lenovo HX03 band obviously because it sports a color TFT display whereas the Mi band 2 only has a 0.42 inch OLED display which is black and white. But the larger display fun only lasts till you wear your band outside, under sunlight. Here, the Lenovo band is useless in bright sunlight as its TFT LCD display gets washed out but the MI band 2 still manages to keep it bright enough to see the information on the screen. But overall, in Gym, or while you play games or exercise in indoors or minimum sunlight, Lenovo HX03 will be a better option.
In addition, the bigger display in Lenovo band lets it show the contents of the notifications like your WhatsApp messages on the band screen right away without opening your smartphone. This is a good thing since you can save you a lot of time unlocking your device if the message is not important or you don’t have to reply back.
Also, there are some complaints about Mi Band 2 display as the OLED display gets worn out after some time at least on some units they have sold.
Moving on to the design, especially talking about the straps, both the smart bands have got silicon-based rubberish straps from the factory. But I feel the strap on the Lenovo band is a better deal because it is larger and it has a lot of holes where you can comfortably adjust to your size of the wrist which is very important for the accuracy of the sensors. Also, the buckle is made up of metal on the Lenovo band where is in the MI Band 2 it is just a part of the strap itself made with the same material.
Sensors & Accuracy
Both the smart band’s sports an optical heart rate sensor. But when you look closely, the Mi Band 2 has two emitting sensors whereas the Lenovo has just one. It turns out that the heart rate accuracy is far better in Mi band 2 than in Lenovo HX03, not sure it has something to do with the sensor arrangement. Mi band 2 is generally very fast while measuring the heart rate but the Lenvov struggles most of the time.
When it comes to sleep tracking, in my experience, both bands are not good enough. however, Mi Band 2 presents a better data that Lenovo which provides data which is far away from actuals.
With Mi band 2, you get 2 very basic watch faces, one with date and the other one without – pretty basic and monotonous. But when it comes to customization and watch faces Lenovo is the King in this price range. It provides 5 watch faces, two analog and 3 digital faces – thanks to the TFT LCD display.
Talikg about the supporting fitness app, the Mi-Fit app for Mi Band 2 has a lot of options compared to the Lenovo App. For example, the Mi app can store the sleep data for 30 days where the Lenovo app just can’t. It is not like the Lenovo app is not good enough but in terms of features and the way UI is, Mi-Fit does a better job.
Battery and charging
As shown in the specs, Mi Band 2 will last about 15-20 days if you use it every day or even 30 days if you use it occasionally. In case of Lenovo band, the battery lasts for 7-10 days which is less but we have to pay a price for the color TFT display. Still, it is a good deal because most of the other bands with similar display struggles to give 10 days battery backup.
One thing I really dislike about Mi band 2 is that there is a charging cable you have to carry around if you want to charge the band. This is really not helpful as most of the time you might miss it or its an extra luggage. With Lenovo band, you can plug it into any of the normal USB port and charge it by that way you can forget about taking anything extra for the band if you are traveling.
Mi Band 2 Pros
- 20-30 days battery backup
- Consistent step tracking
- Near to accurate heart rate tracking
- Helpful idle alerts
- Non-convenient charger cable
- Display wears out for some customers after sometime
- Inaccurate sleep data
Lenovo HX03 Spectra Pros
