Xiaomi Mi Band 1S (Updated 7th Nov 2015)

November 7, 2015

Leaks of the Xiaomi Miband 1S from Anzhuo has allowed us a clearer view of the rumoured optical light sensor on this highly anticipated successor to the original Xiaomi MiBand.


According to the leaks, the Xiaomi Miband will retail for 100 RMB or the equivalent of about 15 USD. Yes, you heard me right. Before you fall off your chairs, do note that the new wearable from Xiaomi is also rumoured to feature heart rate measurement at rest and during activity. Now you can continue the fall from your chairs. If this leak is indeed true, we can expect the Miband 1S  to continue its gain on the fitness wearable tech market.

After looking at the leaked pictures, my main concern is accuracy. That being said, I am also aware there are a lot of people out there who are basically interested to have an estimate of their heart rate rather than have it ECG grade. Even the best of optical light sensor heart rate monitors are unlikely to achieve the same accuracy attained during validations in lab settings so perhaps Xiaomi might be on to something.

The release date is rumoured on the 11th November on I’ll be following this piece of news very closely.

According to a post on Sogi, Xiaomi Mi Band 2 has passed through Taiwan’s NCC. From leaked photos, the Mi Band 1S appear to be identical to the original Xiaomi Mi Band, save for a optical heart rate sensor on the back of the tracker unit.


The 2 charging pins at one end with changeable straps is in line with Mi Band’s original design. There’s no word on other details such as pricing, release date or battery duration.

In 2015, the Xiaomi Mi Band gained compatibility with Google Fit and the mobile app reached both Android and iOS platforms. There’s still not social platform to add friends though sharing is convenient with in-app functions.


As with other trackers on the market, the addition of an optical heart rate sensor will no doubt make a dent in the legendary 30 days battery lifespan the original Xiaomi Mi Band had.

The Xiaomi Mi Band is a personal favourite of mine when it comes to ranking tracking devices. The ridiculously low priced tracker with a multitude of functions literally slaps other companies across the face when it comes to value for money. You can check out my review of the Mi Band here.

I will update as soon as there’s more information about the Xiaomi Mi Band 1S.
