Under the hood, it’s powered by a dynamic dual-processor setup (Snapdragon W5 + BES2800) ensuring everything runs buttery smooth. Plus, with up to 18 days of battery life in power-saving mode, you won’t be constantly searching for a charger.

But what truly sets the Xiaomi Watch 5 apart for this car integration is its cutting-edge health and connectivity features. It’s the first Xiaomi wearable to include an EMG sensor for micro-gestures, alongside an ECG for on-demand electrocardiograms. These aren’t just fancy health trackers; they represent a commitment to intuitive interaction within the broader Xiaomi ecosystem, perfectly complementing the Xiaomi electric cars.

Speaking of cars, the SU7 is Xiaomi’s pioneering electric sedan, while the SU7 Ultra is its extreme, high-performance variant. The YU7, launched in June 2025, is Xiaomi’s luxury electric SUV, ready to rival the Tesla Model Y. With impressive ranges up to 835 km and hyper-sporty acceleration in Max versions, these vehicles are already pushing boundaries.
