Xiaomi has reportedly intensified internal testing for its forthcoming HyperOS 3, which is set to run on Android 15, with a dozen of its devices currently undergoing evaluation. As of November 7, 2025, while no immediate public announcements have been made, industry reports and code leaks suggest the company is actively preparing for its next major operating system rollout.

Xiaomi Intensifies HyperOS 3 Internal Testing

Internal testing for HyperOS 3, layered over Android 15, is underway on 12 distinct Xiaomi phone models. This development comes after Android Police reported on November 6, 2025, that Xiaomi is ramping up its Android 15 beta testing efforts. The list of devices confirmed through cross-verified leaks from sources like XDA Developers and GSMArena includes flagships and popular mid-range models.

The devices currently under internal testing, which began around mid-October 2025, are:

• Xiaomi 14

• Xiaomi 14 Pro

• Xiaomi 13T Pro

• Xiaomi 13T

• Xiaomi 13

• Xiaomi 13 Pro

• Xiaomi 12T Pro

• Xiaomi 12T

• Redmi K70

• Redmi K60 Ultra

• Redmi Note 13 Pro+

• Redmi Note 12 Pro

Although official statements regarding HyperOS 3 have yet to be released by Xiaomi as of November 7, the company did issue a press release on October 15, 2025, confirming ongoing development of "next-generation OS updates" aligned with Android 15. This release emphasized an enhanced focus on ecosystem integration across devices. Speculation from 9to5Google and TechRadar suggests a public debut for HyperOS 3 could happen by Q1 2026.

Expected Features and Performance Enhancements

HyperOS 3 is anticipated to bring substantial improvements and new functionalities. Leaks point to AI-driven features like real-time translation within applications and an enhanced "HyperIsland" for seamless cross-device continuity, enabling smooth task switching between phones and tablets. Advanced privacy controls, including scoped storage and app hibernation, are also expected. Xiaomi's own AI tools, powered by Gemini, further differentiate the OS.

Performance benchmarks suggest notable advancements. Early tester leaks indicate up to a 15% improvement in battery life with Android 15 betas, while HyperOS 3 itself is reportedly delivering 20% faster app launch times based on synthetic benchmarks. Tested flagships are averaging AnTuTu scores of 1.2 million. Compared to HyperOS 2, the new iteration is said to offer 25% better energy efficiency and a 10-15% reduction in RAM usage for multitasking. Camera processing also sees improvements, leveraging Android 15's under-display enhancements. Furthermore, HyperOS 3 aims to be lighter than its MIUI predecessors, boasting a 20% smaller footprint for quicker boot times. Monthly security patches will continue, with an added focus on AI-powered anti-malware measures.

Rollout Outlook and Regional Considerations

The stable rollout of HyperOS 3 is projected to commence in Q1 2026 for flagship devices, with beta access potentially opening in December 2025 for 8 to 10 models. Xiaomi has also committed to at least four years of OS updates for its flagship devices, according to Google's official Android blog from October 25, 2025.

Regionally, testing in China is more advanced, with beta builds for devices like the Redmi K70 available since early October 2025. However, global markets, particularly the EU and India, may experience delayed rollouts. This is largely due to the need for regulatory compliance, with the EU requiring specific privacy tweaks to meet GDPR standards. In India, Xiaomi's press event on October 25, 2025, hinted at prioritizing mid-range devices such as the Redmi Note 13 series for the Android 15 update. The US market will primarily see availability through unlocked models, with carrier versions not expected until Q2 2026. Xiaomi's global Android update adoption rate stands at 65% for eligible devices within the first year, providing context for the upcoming HyperOS 3 deployment.
