Xiaomi's next major software update appears to be nearing release.
Industry insiders suggest HyperOS 4 could officially launch as early as next month (August), bringing a redesigned interface, extensive under-the-hood changes, and several AI-powered enhancements for compatible Xiaomi devices.
Performance, design, and AI upgrades
According to leaks from Chinese sources, HyperOS 4 has been rebuilt using the Rust programming language alongside the Flutter development framework for its core components.
The update is said to remove legacy MIUI code completely, resulting in a cleaner system architecture.
Early test figures suggest the new software could improve overall system smoothness by around 40 percent, increase background app retention by 35 percent, and reduce idle memory consumption by 25 to 30 percent.
Reports also claim that performance degradation after a year of continuous use could be limited to just 5 percent.
HyperOS 4 is also expected to introduce Xiaomi's new Liquid Glass design language, featuring softer 2.5D-inspired visuals and two interface styles, including Transparent and Soft modes.
The update is tipped to strengthen cross-device connectivity across smartphones, tablets, smart home products, and vehicles.
File transfer speeds between supported devices could increase by up to 300 percent, while app continuity across screens is also expected to become more seamless.
A unified AI coordination framework is said to improve communication between Xiaomi devices.
The update is also rumored to integrate Xiaomi's on-device AI models, including Mimo and the Miclaw AI agent, enabling offline features such as document summarization, multilingual translation, and AI image editing.
Since these capabilities run locally, they are expected to offer better privacy while delivering responses significantly faster than cloud-based AI services.
If the current timeline remains unchanged, HyperOS 4 could debut alongside the Xiaomi 18 series or Xiaomi's next-generation foldable smartphone before gradually rolling out to devices such as the Xiaomi 17 series, Xiaomi 15 series, and Redmi K90 series.
