Availability may vary by device, and users should check their phone's software update section to see whether the update has arrived.
Xiaomi opened the HyperOS 4 beta programme in China on August 14, 2026. The company expanded beta testing to global users in September. The second global beta batch also included the Xiaomi 15, Xiaomi 15 Ultra, Xiaomi 17T and Xiaomi 17T Pro.
However, the stable release remains limited to China for now. Xiaomi has not confirmed when other markets, including India, will receive the final version.
HyperOS 4 Features: Faster Loading And Better Memory Management
The latest update focuses on improving how the operating system manages resources. Xiaomi has introduced two technologies to its in house HyperCore kernel: load calculation and memory preloading.
Here are the key changes:
- Faster app loading: Memory preloading could help applications open more quickly.
- Improved resource management: Load calculation helps the system manage workloads more efficiently.
- Smoother performance: The updated system aims to reduce lag and make screen transitions more responsive.
- Cleaner interface: Xiaomi has reduced decorative animations and unnecessary visual elements for a simpler appearance.
Xiaomi first introduced its HyperCore kernel with HyperOS 2. HyperOS 4 builds on this foundation with improvements to system level resource scheduling.
Early beta testers have reported smoother transitions and fewer noticeable delays. However, the final experience may vary depending on the device.
For now, Xiaomi users outside China will need to wait for the official global stable rollout announcement. The company has yet to share a confirmed timeline for the wider release.
