Smart watches Xiaomi Mi Watch, as it turned out, are running Wear OS, albeit using a special version of the MIUI shell.
The heart of the watch is also the Snapdragon Wear 3100 single-chip system typical of modern models with Wear OSs. Therefore, the officially declared autonomy of 36 hours, though not pleasing, is a quite expected value.
However, if you do not remember that the Xiaomi watch has a huge battery with a capacity of 570 mAh by the standards of the class. And it seems that he still makes the Mi Watch more autonomous than most other watches with Wear OS.

According to sources, the Xiaomi media director on the Weibo network posted a screenshot according to which his Mi Watch had already worked 57 hours and saved 10% of the battery charge. That is, the total autonomy should exceed 60 hours. And for a full-fledged smart watch, this is already quite good, even if Samsung devices show better results.
