Xiaomi 17 Pro Max “secret mode” revealed: hidden settings & tricks
Unlocking Advanced Tools Inside HyperOS 3
The Xiaomi 17 Pro Max includes several hidden options inside HyperOS 3 that aren’t immediately visible to new users. These tools can improve performance, enhance security, streamline multitasking and unlock extra features from the secondary display. Exploring these settings can make the device feel more powerful and personalised in everyday use.
One of the standout hidden features is the customisation menu for the rear display. By going into the advanced settings, users can adjust clock styles, set quick-access widgets and enable notifications that appear only on the secondary screen. This helps save battery and makes simple actions faster, such as checking music controls or viewing alerts without waking the main display.
Gesture shortcuts add another layer of quick interaction. The double-tap and triple-tap back gestures allow users to launch the camera, turn on the flashlight or open specific apps instantly. These gestures reduce the need to stretch across the large display, especially useful when using the device with one hand. Customising these shortcuts creates a smoother and more efficient navigation experience.

Floating windows and the smart sidebar are features that many users overlook. They allow apps to run in smaller resizable windows on top of the main screen, making multitasking easier on the 6.9-inch display. The sidebar can hold frequently used apps, tools and functions that open instantly with a swipe. This tool is especially effective for messaging, browsing or quickly referencing information while watching videos.
Battery health optimisation is another setting that becomes essential for long-term use. HyperOS includes options that slow down charging during overnight sessions, limit maximum charge levels and reduce background power drain. These tools help maintain battery longevity, particularly for users who rely on fast charging during the day but prefer healthier battery management when idle.
System cleanliness also improves through hidden toggles. Users can disable system suggestions, remove promotional notifications and turn off background services that rarely contribute to performance. Disabling the advertisement-related system services results in a cleaner, smoother interface that feels more premium. For many users, this substantially improves the overall experience.
Inside the camera app, hidden enhancements provide more creative control. Pro mode allows manual adjustment of ISO, shutter speed and focus, making it easier to capture stable shots in low light. The option to use the front screen as a fill light for selfies is another trick that helps brighten video calls and portrait shots. Combined with the periscope lens and high-resolution sensors, these tools unlock additional photographic potential.
For users who record video frequently, stabilisation and performance-boost settings inside the camera and battery menus make a noticeable difference. These tools reduce shake during handheld recording and allow the phone to prioritise camera processing when needed. They ensure that clips remain smooth even when shooting at higher resolutions or using zoom.
HyperOS also includes hidden privacy functions. App permission monitors, clipboard protection and secure folder options keep sensitive content private. Users can audit which apps access camera, microphone or location in real time, offering better transparency and control. These features aren’t always highlighted but add meaningfully to everyday security.
Finally, performance tweaking options inside developer settings allow users to adjust animation speeds, accelerate transitions or keep background processes active for smoother multitasking. Though not required for all users, these settings can make the device feel even faster and more responsive when used correctly.
Altogether, the hidden settings and secret tools of the Xiaomi 17 Pro Max make the software experience more capable and customisable. Exploring these features helps users extract more value from their flagship device, ensuring it feels efficient, powerful and tailored to their personal workflow.
