Xiaomi took advantage of the showcase offered by the Mobile World Congress to expand its range of smartwatches with two new proposals, very interesting in design and characteristics. On the one hand, the company introduced Xiaomi watch 2smartwatches with WearOS from Google, and on the other Xiaomi watch S3which is more focused on use with the company’s ecosystem thanks to HyperOS and its integration with the entire Xiaomi platform.
On paper, these are relatively similar devices with very similar design and features (both round body and design), which have the same screen size and characteristics that are measured from person to person, and whose main difference is the operating system that controls both devices.
This is a very interesting move from Xiaomi, which is now starting to offer two very similar devices. but intended for a completely different audience: those who want to stay in the Xiaomi ecosystem with HyperOS, or those who are looking for something more that matches the capabilities that Google offers with its WearOS and its integration into Android.
