The successor to Xiaomi's Mi Band has not been announced yet, but it was spotted recently in a wearable conference in China. Unexpectedly, the Mi Band 2 was seen being worn by none other than Xiamoi's own CEO, Lei Jun.

Based on the picture posted by Chinese website Weibo, the upcoming Mi Band 2 looks entirely different from its predecessor. The new model comes with a big upgrade as it now has an LCD and a physical button. The LCD displays all the information related to physical activity for the hour or for the day, The Verge reported.

Jun was wearing a color black Mi Band 2 and the button is speculated to be the mode button for displaying one's fitness data on its display screen. The silicone strap seems similar to the original Mi Band.

The first Xiaomi Mi Band does not have an LCD display so nothing can be displayed on the fitness tracker; thus, every piece of information must be accessed on the accompanying application that needs to be installed on an Android phone. The company's first fitness wearable can record the number of steps the user has made anytime of the day, calories burned, and distance traveled. It can also keep track of one's sleeping habits, remind one to wake up, as well as when it is time to get some shut-eye.

Additionally, when using a suggested Mi smartphone, the Mi Band can unlock it for the user without touching the screen.

Xiaomi's Mi Band has taken the wearable community by storm. It was merely priced at US$15 and was considered to be a successful product.

No other information is available for the upcoming fitness tracker by Chinese tech company. It is not known if it will be as affordable as its predecessor.

Android Headline added that the Mi Band 2 is expected to be unveiled officially on May 10, together with Mi Max smartphone, rumored to have a 6.4-inch display screen and a Snapdragon 820 chipset.
