The software has received support for new sports modes and improved sleep analysis algorithms REM. whereas the old models could only record superficial and deep sleep, the new version details the phase data and provides recommendations for recovery.

The weight of the device is only 18 grams without a strap, making it almost weightless on the wrist, which is especially important for monitoring night sleep, when any extra gram can cause discomfort, and the straps from the fluoroelastomer have become softer and hypoallergenic, which reduces the risk of skin irritation when worn for long periods.
The accessories line includes not only sports but also classics: leather straps and metal bracelets from Milanese weaving, which transforms the tracker from a sports gadget into a full-fledged element of everyday style, fastening allows the use of third-party accessories, expanding the possibilities of customization.

Autonomy and Charging Features
The question of how much battery holds remains a key one for wearable electronics owners. Xiaomi Smart Band 9 features a 200 mAh battery, which, when combined with optimized software, provides up to three weeks of operation. Real use time is about 14-16 days with continuous pulse monitoring and notifications enabled.
The charging process is faster thanks to the support of the fast charging protocol, which takes about 60 minutes to fully recover the capacity, and uses a magnetic connector to recharge, which is securely fixed in the recess on the back of the capsule.
It is important to note that the package often does not include a network adapter, only a cable. Use a power supply with a current of 0.5 A or 1 A. The use of powerful charges from smartphones with support for Fast Charge or SuperCharge will not damage the device thanks to the controller, but will not speed up the process significantly.
