Xiaomi has expanded its HyperOS 3.1 beta to twelve additional smartphones and tablets, marking the first Android 16‑based test on flagship models such as the Xiaomi 14 Ultra and the entire Xiaomi 15 series. The update, identified as version 3.0.300, arrives via OTA in mainland China and focuses on polishing performance, battery life, and gesture handling without a major UI overhaul.
Rollout Details and Version Info
Beta Build Numbers
The second‑phase beta is labeled version 3.0.300 with device‑specific suffixes. For example, the MIX Flip 2 receives 3.0.300.6.BETA while the Pad 7 Ultra runs 3.0.300.2.BETA. Consistent major versioning across flagship and mid‑range models indicates a unified Android 16 codebase.
Background on HyperOS 3.1
HyperOS is Xiaomi’s custom skin built on Android, launched in 2023 to streamline the fragmented Android ecosystem. The initial HyperOS 3.1 beta was limited to the Xiaomi 17 and K90 series, serving as a stability test for the early Android 16 preview. Extending the beta to newer flagships demonstrates Xiaomi’s confidence in the platform’s maturity.
Devices Included in the Second Batch
- Flagship smartphones: Xiaomi 14 Ultra, Xiaomi 15, Xiaomi 15 Pro, Xiaomi 15 Ultra
- Upper‑midrange: Redmi K80 Pro
- Foldable & flip: MIX Flip 2
- Tablet: Xiaomi Pad 7 Ultra
Implications for Android 16 and the Ecosystem
- Stability validation – Flagship hardware stresses performance, power management, and camera integration, providing real‑world data on Android 16 stability.
- Unified codebase – The shared 3.0.300 version suggests Xiaomi is consolidating Android 16 adaptations, which can simplify future OTA updates.
- Enhanced feedback loop – A broader Chinese user base yields richer bug reports and performance metrics, shaping the final public release.
- Competitive edge – Accelerated beta deployment may give Xiaomi a timing advantage over rivals racing to ship Android 16‑based skins.
What Users Can Expect from the Beta
The beta does not overhaul the UI; instead, it delivers incremental refinements such as smoother animations, improved gesture handling, and tighter integration of native apps with Android 16 services. Early adopters report fewer crashes and more consistent battery behavior. The update is delivered via the standard OTA mechanism, and users can opt‑in through the “System Update” menu.
Future Outlook for HyperOS 3.1
By widening beta access to twelve additional devices, Xiaomi aims to cement Android 16 as the foundation for its next‑generation products. If testing proceeds smoothly, a stable HyperOS 3.1 rollout to the global market is expected later this year, potentially setting a new benchmark for stability and feature cohesion among Android custom skins.
