It also has a super smart helper that can write down what people say in meetings or help you find things in pictures, making your phone feel much smarter and faster, like a tiny super-computer in your pocket.
Analysis
HyperOS 4 Design
Xiaomi's HyperOS 4 introduces a significant overhaul to its user interface, adopting an aesthetic inspired by glass surfaces. This design philosophy incorporates lighting effects and transparencies, aiming to deliver a more modern and cohesive visual experience across the entire system. The new graphics engine leverages advanced rendering techniques to create realistic reflections and light refractions within menus, windows, and panels, enhancing the visual appeal on both compatible smartphones and tablets.
Beyond the core visual changes, HyperOS 4 also expands customization options for users. The lock screen now offers greater flexibility for integrating various visual elements and notifications, allowing for a more personalized look. Furthermore, users can resize folders to suit their preferences, and widgets can be grouped together to optimize screen space. These design enhancements are complemented by refined transitions between vertical and horizontal orientations, ensuring visual continuity, and dynamically adapting floating applications for a consistent presentation.
Performance Enhancements
A key focus of HyperOS 4's development has been to significantly improve the overall fluidity and responsiveness of the system. Xiaomi's internal tests indicate that application opening times can be up to 18% faster, particularly after extended periods of device use. This improvement is partly attributed to the integration of resource prediction mechanisms, which proactively load necessary information into memory before it is explicitly requested by the user, thereby reducing waiting times and enhancing application responsiveness.
The camera experience also benefits from specific optimizations within HyperOS 4. Xiaomi reports a reduction in HDR photo processing time to just 240 milliseconds, alongside a decrease of approximately 200 milliseconds in the cold opening time of the native camera application compared to previous versions. These performance gains extend to video playback and system animations, which are expected to exhibit greater stability in frame management, contributing to a smoother and more consistent user experience across various device functions.
Artificial Intelligence
Artificial intelligence is a central pillar of HyperOS 4, with the system integrating the new Super AI Assistant 2.0, powered by Xiaomi's proprietary MiMo language model. This advanced AI assistant offers a range of compelling features, including voice transcription capabilities, automatic organization of meeting notes, and unified control over compatible smart home devices. The platform also extends its AI-driven interaction capabilities to connected cars, further integrating the digital ecosystem.
Xiaomi has also innovated in how AI-related tasks are presented to the user. Instead of immediately occupying the entire screen, certain AI queries initially display their status around the front camera cutout. The full interface only expands once the system has generated a complete response, offering a less intrusive user experience. Another notable AI feature is "Inspiration Ball," a contextual tool designed to streamline daily actions, enabling users to interact with addresses for navigation or identify products within images, though its regional availability may vary.
Key points
- Xiaomi has officially launched HyperOS 4, based on Android 17, with a public beta starting August 14 in China.
- The new OS features a glass-inspired design with enhanced visual effects and increased customization options for the lock screen and widgets.
- Performance improvements include up to 18% faster app opening, reduced camera processing times, and better system fluidity.
- HyperOS 4 integrates Super AI Assistant 2.0, powered by the MiMo language model, offering voice transcription and smart device control.
- A new contextual tool called "Inspiration Ball" and an innovative AI task display around the front camera are also introduced.
- The international rollout for Europe and other markets is expected soon after the China beta, but specific dates are not yet confirmed.
The rollout of HyperOS 4 could significantly enhance the user experience for Xiaomi device owners in Europe, offering a more fluid interface, faster performance, and advanced AI features. This could boost Xiaomi's market position and user satisfaction, potentially driving further innovation in mobile operating systems across the continent.
The phased rollout, starting in China with an unconfirmed international date, could lead to frustration among European users eager for the update. Regional variations in feature availability, such as for "Inspiration Ball," might also create an inconsistent experience, potentially dampening enthusiasm for the new OS.
