Xiaomi HyperOS 3 Lock Screen Fonts: Zhuzi, Coca-Cola, and Care - A One-Week Hands-On Test
I tested HyperOS 3 on the Xiaomi 13 series for one week, carrying it everywhere from crowded streets in Mumbai to quiet corners of my home. I explored every corner of the lock screen, tried out all the new fonts, and customized the interface in ways most reviews don’t cover. Instead of repeating spec sheets or marketing claims, I lived with the system, testing it under real-world conditions. From notifications to theme tweaks, HyperOS 3 revealed clever improvements and a few minor frustrations that you won’t see in a short hands-on video.Why I Tested HyperOS 3 Differently
Most tech sites get a device for a few hours or one day. They take a few screenshots, check a couple of features, and call it a hands-on. I spent seven full days testing HyperOS 3 on a Xiaomi 13, paying attention to how the lock screen, fonts, and customization options actually affect daily use.Here’s why this approach matters:
- Real-world testing shows the small wins and annoyances. A font may look great in screenshots but clash with notifications when used all day.
- Customization is deeper than advertised. HyperOS 3 allows you to tweak fonts, colors, and lock screen layouts, but only hands-on use reveals which combinations are practical.
- Behavior in crowded environments matters. Notifications, gestures, and unlocking gestures behave differently when you’re walking, commuting, or multitasking.
This test is unique because it’s based on living with the software, not a rushed demo.
HyperOS 3 Lock Screen Fonts: Zhuzi and Coca-Cola
One of HyperOS 3’s standout features is its lock screen fonts. Xiaomi introduced new styles, including Zhuzi a clean, modern font and Coca-Cola a playful, rounded style inspired by the famous logo.Zhuzi Font: Minimalist and Functional
Zhuzi is perfect if you want:
- Clear readability under bright sunlight
- Less clutter on notifications
- A modern feel without overwhelming the screen
I used Zhuzi for three days during outdoor testing. Walking through sunlight-heavy streets in Mumbai, I noticed that notifications remained readable even at extreme angles. Text contrast is consistent, and the lock screen looks neat even when multiple notifications pile up.

Coca-Cola Font: Fun but Practical
The Coca-Cola font is more playful. It looks great for personalizing your device and adding a casual style to the lock screen. However, during real-world use, I found:
- It slightly reduces readability under harsh sunlight
- Works best for low-notification scenarios
- Feels more suited to casual users or younger audiences
If you want a fun, unique look, Coca-Cola works. If you want function first, Zhuzi wins.
Care Features: Lock Screen Health and Accessibility
HyperOS 3 adds Care features, which include subtle indicators for battery health, notification priority, and accessibility shortcuts directly on the lock screen.
Real-World Observations:
- Battery Health Shortcut: Easy to see your battery percentage at a glance. It also provides alerts for unusual battery drain.
- Notification Priority: You can highlight critical messages while keeping other notifications minimized. In crowded Mumbai streets, this reduced distraction without missing important updates.
- Accessibility Tools: HyperOS 3 allows quick access to magnification, color inversion, and high-contrast modes. I tested these with both bright and low-light conditions highly useful for anyone needing visual adjustments.
Daily Life Testing: What Worked and What Didn’t
Over the week, I noticed how small design decisions affect daily use:What Worked Well:
- Gestures: Lock screen gestures are intuitive. Swipe down for quick notifications, swipe up to unlock very responsive.
- Customizable Widgets: HyperOS 3 lets you add weather, calendar, or music widgets directly to the lock screen. Real-life use shows they’re stable and visually clear.
- Themes and Personalization: Fonts, color schemes, and wallpapers combine seamlessly without crashes.
Minor Frustrations:
- Notification Overlap: On certain wallpapers, text can blend slightly with the background. Some font-color combinations need manual tweaking.
- Coca-Cola Font in Sunlight: Not ideal for outdoor readability.
- Initial Setup Confusion: Some Care features require digging through menus first-time users may miss them.
Unique Observations: What You Won’t See in Typical Reviews
Here’s where my one-week test stands out:
- Font and wallpaper synergy matters. Certain wallpapers make Coca-Cola unreadable unless combined with shadow overlays.
- Lock screen widgets consume less battery than expected. In my full-day stress tests, battery drain was negligible even with multiple widgets active.
- Gestures feel natural in motion. Many reviewers test phones on a desk. Walking with the phone shows how fluid HyperOS 3 really is.
- Subtle animation improvements. Unlocking animations and font transitions feel smoother than MIUI 14, making everyday use more pleasant.
Hands-On Test: Zhuzi vs Coca-Cola Fonts
I conducted a simple real-world test:
- Location: Mumbai streets, office, home
- Duration: 7 days
- Parameters: Visibility, readability, stress under bright light, notification load
Results:
- Font Readability Practicality Style
- Zhuzi Excellent High Modern
- Coca-Cola Good Medium Playful
Real-World Care Feature Insights
HyperOS 3 isn’t just cosmetic it adds meaningful utility:- Battery Alerts: I received warnings when a background app consumed extra power, helping me prevent sudden drain.
- Notification Grouping: Multiple messages from apps like WhatsApp or Gmail were grouped effectively on the lock screen, reducing clutter.
- Accessibility Shortcuts: One-tap magnification worked perfectly in both bright sunlight and dim indoor lighting.
Tips for Maximizing HyperOS 3 on Your Xiaomi Device
- Choose fonts wisely: Zhuzi for function, Coca-Cola for style.
- Pair with wallpapers carefully: High-contrast backgrounds improve readability.
- Enable Care features: Unlock hidden utilities that can save battery and reduce distractions.
- Test widgets: Only use what you need; too many can crowd the lock screen.
Who Will Benefit Most from HyperOS 3
Based on my hands-on experience, HyperOS 3 is ideal for:
- Users who enjoy personalization: Fonts, widgets, and layouts are flexible.
- Busy professionals: Notification grouping and Care features reduce distractions.
- Tech-savvy users: The system allows subtle tweaks that enhance real-world usability.
It may not suit:
- Users who prioritize maximum readability under extreme sunlight with playful fonts.
- People who prefer a fully static lock screen Jowithout experimentation.
Final Verdict After One Week
HyperOS 3 is more than a minor MIUI upgrade. It improves lock screen functionality, adds meaningful personalization, and balances aesthetics with utility. Fonts like Zhuzi and Coca-Cola provide choices for both functional and stylistic users. Care features improve battery awareness and notification management in real-world scenarios.For those who want a device they can customize, live with, and truly use in daily life, HyperOS 3 delivers an experience that no rushed hands-on review can capture.
