A new leak suggests that the forthcoming Xiaomi Mi Band 5 fitness tracker will feature a raft of new features that could make it a super-affordable alternative to activity bands from the likes of Fitbit and Garmin.

According to TizenHelp, a site specializing in wearable news, the Mi Band 5 will feature an SPO2 sensor for measuring blood oxygen concentration while you sleep, menstrual cycle tracking, and Amazon Alexa support for controlling your smart home devices with voice commands.

We've already heard that the Mi Band 5 will feature global NFC (a feature that was previously only available in China) for contactless payments, and these tools combined would make it a very tempting proposition for anyone looking for a budget-friendly fitness tracker.
