The HyperOS 4 launch could take place as early as August, according to the latest leaks from China. Xiaomi’s next major software update will introduce a refreshed design, better performance, stronger cross-device connectivity, and several new AI-powered features. Reports suggest HyperOS 4 will debut alongside the upcoming Xiaomi 18 series or the company’s next foldable smartphone before reaching eligible Xiaomi and Redmi devices.
If the leaks are accurate, HyperOS 4 could become Xiaomi’s biggest software upgrade in recent years by focusing on speed, efficiency, and smarter on device AI capabilities.
HyperOS 4 Launch May Bring Faster Performance And New Design
According to industry sources, Xiaomi has rebuilt HyperOS 4 using the Rust programming language and the Flutter development framework. The update will also remove all remaining legacy MIUI code, resulting in a cleaner, more efficient software architecture.
Early testing reportedly shows significant performance improvements across supported devices.

Expected HyperOS 4 Performance Upgrades:

- Up to 35 percent better background app retention
- 25 to 30 percent lower idle memory usage
- Only 5 percent performance drop after one year of regular use
HyperOS 4 is also expected to introduce Xiaomi’s new Liquid Glass design language. The refreshed interface could offer softer visuals inspired by 2.5D effects and include two themes called Transparent Mode and Soft Mode.
AI Features And Device Connectivity Expected to Improve
The HyperOS 4 launch is also expected to focus heavily on artificial intelligence. Xiaomi may introduce its latest on-device AI models, including Mimo and the Miclaw AI agent, allowing users to perform several tasks without an internet connection.
Expected AI Features:
- Offline document summarisation
- Multilingual translation
- AI powered image editing
- Faster responses with better privacy
The software is also expected to improve connectivity across Xiaomi smartphones, tablets, smart home products, and vehicles. Reports claim file transfer speeds between supported devices could become up to 300 percent faster, while app continuity across multiple screens may become more seamless.
If Xiaomi follows its expected schedule, HyperOS 4 will first arrive with the Xiaomi 18 series or the company’s next foldable phone. The update is then likely to roll out gradually to devices including the Xiaomi 17 series, Xiaomi 15 series, and Redmi K90 series.
Although Xiaomi has not officially confirmed the update, the latest leaks suggest the HyperOS 4 launch is now just weeks away. With major performance improvements, a redesigned interface, and powerful offline AI features, HyperOS 4 could deliver one of the biggest software upgrades for Xiaomi users in 2026.
