Xiaomi has finally started rolling out the long-awaited HyperOS 3 based on Android 16 update for the Xiaomi 13 Ultra, bringing it in line with the company’s latest Ultra lineup software experience. After successfully delivering HyperOS 3 to the Xiaomi 15 Ultra and Xiaomi 14 Ultra last month, Xiaomi is now expanding the rollout to its 2023 flagship, much to the relief of long-time users.
The HyperOS 3 update for Xiaomi 13 Ultra is arriving with the OS3.0.1.0.WMAMIXM (global) build number and carries a hefty 6.9GB download size. As with most major Xiaomi updates, the rollout is being conducted in batches, which means not every user will receive it at the same time. If the update hasn’t appeared yet, patience is key—keep checking the system updater regularly, as it should reach all eligible devices gradually.
Alongside Android 16, this update also integrates the December 2025 Android security patch, significantly strengthening device security. The latest patch addresses critical system vulnerabilities, improves protection against malicious apps, and enhances overall system resilience, making the Xiaomi 13 Ultra safer for daily use.
HyperOS 3 brings a noticeable refinement to the overall user experience on the Xiaomi 13 Ultra. System animations are now smoother and more consistent, with reduced stutters during multitasking and app switching. Xiaomi has further optimized memory management, allowing heavy apps and camera processes to stay active longer in the background—something power users and mobile photographers will appreciate.
Battery performance has also been improved under HyperOS 3. Thanks to smarter background activity control and refined power scheduling in Android 16, users can expect more stable screen-on time and reduced idle battery drain. Thermal management has been tuned as well, helping the device maintain peak performance during extended gaming or 4K video recording sessions without aggressive throttling.
On the visual side, HyperOS 3 introduces refreshed system UI elements, cleaner notification animations, and improved lock screen customization. Users get more control over clock styles, widgets, and depth effects, giving the Xiaomi 13 Ultra a more modern and personalized feel. The always-on display has also been optimized for better readability and lower power consumption.
Privacy and security see major enhancements with Android 16 integration. HyperOS 3 includes improved permission controls, more transparent background access indicators, and tighter restrictions on sensitive data usage. App behavior monitoring is smarter now, ensuring suspicious activity is flagged faster without impacting performance.
Camera performance, a key strength of the Xiaomi 13 Ultra, benefits from backend optimizations in HyperOS 3. Image processing feels faster, shutter lag is reduced in certain scenarios, and overall camera app stability has been improved. While no major camera UI overhaul is included, the under-the-hood refinements enhance reliability during intensive shooting sessions.
Overall, the HyperOS 3 Android 16 update marks a significant milestone for Xiaomi 13 Ultra users. With smoother performance, better battery efficiency, stronger security, and refined system polish, the device remains firmly competitive even in 2026. If you haven’t received the update yet, stay patient—once it arrives, it’s well worth the wait.
