Lenovo launched a new set of fitness bands in April this year and one of them is the Lenovo Fitness Band HX03F. This smartband has been launched to compete with the likes of the Xiaomi Mi Band 2 and its newest iteration the Xiaomi Mi Band 3. There are a few options in terms of the band colors for the HX03F, but we received the one with the black straps and here s my review of the Lenovo HX03F Spectra.

The Lenovo HX03F Spectra does not stand out much if one were to just glance it in passing. But this device has a curved 2.5D glass which gives smooth rounded edges to the device. The main watch unit has a black screen that is surrounded by a dark grey plastic body with a matte texture. Also Read - Best laptops under Rs 30,000 for multitasking to buy in October 2021

The straps are interchangeable and the best part is that charging this device does not require any cables. To charge the device, users just need to snap off the strap by pulling off one end of the strap from the watch body. Once the strap is off, it exposes the USB interface inside that is connected to the watch body. This allows you to plug the whole watch into the USB port to charge.

The straps are uniform in how they mesh with the body of the watch, and have a matte finish as well. Coming back to the body of the device, it does not have any buttons which pleasantly surprised me. The only interaction with the watch is through the touch zone that is indicated by a faint white circle at the bottom of the OLED panel.

The UI of the Lenovo HX03F Spectra is simple and efficient to be precise. The home screen has quite a few watch faces that include analog and digital faces. Though the analog ones might look a bit small because the limitations of the display space, the digital ones look rather cool.


The Lenovo HX03F Spectra has few flaws in terms of performance, and works like it has been advertised. The pairing of the smartphone to the smartphone app was seamless and the syncing of the data was quick. The Lenovo HX03F Spectra measures the heart rate every 15 minutes and keeps a tab of it when syncing to the app.

The optical heart rate monitor is pretty accurate and does not seem to falter. The steps calculated by the device is accurate as well and did a much better job than my smartphone. What is really amazing about the Lenovo HX03F Spectra is its battery life. Even after using sports mode everyday, the device lasted over 12 days on a single charge.

But one of the issues that I faced with my device was that the screen refused to light up two out of three times when I had to look at the watch. This could be an issue with the gyroscope, and it persisted. But besides that the Lenovo HX03F Spectra worked as advertised and even underwater.

The Lenovo HX03F Spectra is a new competitor in the smart wearables space and has to put up a strong performance to get ahead, which it has done for the most part. The fitness band is lightweight, has a colored display, is efficient at keeping track of the cardio and has a great battery.

For this price the Lenovo HX03F Spectra seems like a justified buy, and will be a tough competitor in its own market segment. It does face competition, but we’re happy to recommend it as a good option to consider right now.
