Great news for Xiaomi fans eagerly awaiting the next major software update. The global rollout of HyperOS 3, based on the latest Android 16, is progressing rapidly, with the company almost completing its first wave of updates. Now, in an exciting development, the update has begun internal testing for one of its most popular flagship lineups from 2022.
According to the official rollout schedule, Xiaomi is on track to bring the stable HyperOS 3 experience to around 40 global devices by the end of December 2025. The first batch of devices is nearly complete, with only a handful of models like the Xiaomi Pad Mini and select Redmi Note 14 variants left to receive the update, expected by November 2025.
But the real buzz is happening further down the timeline. Devices in the second batch are queued up for their update soon, and now, phones from the third batch are unexpectedly joining the party ahead of schedule.
Xiaomi 13 Series Enters HyperOS 3 Internal Testing
The spotlight is now on the flagship Xiaomi 13 series. Initially launched in 2022, these devices were slated to receive their Android 16-based HyperOS 3 update around March 2026. However, it appears Xiaomi is pushing ahead faster than anticipated.
As first spotted by the tech outlet XiaomiTime, internal test builds for the global versions of the Xiaomi 13 and 13 Pro have been identified. The Xiaomi 13 is testing under build number OS3.0.0.1.WMCMIXM, while the 13 Pro is using OS3.0.0.3.WMBEUXM. The report also notes that a build for the Xiaomi 13 Ultra has been spotted, though it is currently for the Chinese market and not the global variant.
This discovery, detailed by XiaomiTime, is a strong indicator that the stable rollout for the Xiaomi 13 and 13 Pro is being prepared behind the scenes. When a device enters this phase of internal testing, it typically means the public release is not far behind.
What This Means for Your Xiaomi 13
For owners of the Xiaomi 13 or 13 Pro, this is a very promising sign. While the original schedule pointed to a 2026 update, the presence of internal builds suggests a much sooner release window.
Industry watchers now speculate that the global Xiaomi 13 series could start receiving the stable HyperOS 3 update as early as December 2025, a significant jump from the initial timeline. This would place it comfortably within Xiaomi's broader goal of updating all 40 devices by the end of the year.
HyperOS 3 is expected to bring a host of improvements, including enhanced performance, better cross-device connectivity, refined animations, and all the new features offered by the underlying Android 16 operating system.
The Bigger Picture: HyperOS 3 Rollout on Track
The accelerated testing for the Xiaomi 13 series demonstrates Xiaomi's commitment to streamlining its software update process. With the first batch nearly wrapped up and later batches already in testing, the company is showing a focused effort to deliver a consistent and timely software experience to its global user base.
If you're using a Xiaomi 13 or 13 Pro, it's time to get excited. Keep an eye on your system updater in the coming weeks, as the wait for HyperOS 3 appears to be getting much shorter.
