Design & Build

The Xiaomi Smart Band 11 offers more customization, with interchangeable straps and metal, ceramic and other editions. Its slimmer body and different material options give buyers more flexibility when choosing a style. Both fitness bands feature 5ATM water resistance, making them suitable for swimming and everyday water exposure under appropriate conditions.
Winner: Xiaomi – More strap options and premium editions.
Display
The Redmi Band 4 features a 1.47-inch display with a 60Hz refresh rate and 2.5D curved glass. Its screen is suitable for checking notifications and basic fitness information, while the higher refresh rate supports smoother navigation.
The Xiaomi Smart Band 11 upgrades the viewing experience with a 1.72-inch AMOLED panel, 2,000-nit peak brightness and narrow 2mm bezels. The larger screen provides more viewing space, while AMOLED technology delivers richer colours and deeper blacks. Its higher brightness also makes outdoor viewing easier, particularly in bright sunlight.
Winner: Xiaomi – A larger, brighter AMOLED display with a more immersive viewing experience.
Battery Life
Battery life is a strong point for both fitness bands. The Redmi Band 4 and Xiaomi Smart Band 11 claim up to 21 days of battery life, making them suitable for users who prefer less frequent charging. Actual endurance depends on display settings, notifications, and tracking frequency.
Winner: Tie – Both claim up to 21 days of battery life.
Health Tracking
Both bands support heart rate monitoring, blood oxygen measurement, stress tracking, sleep tracking and women’s health monitoring. The Redmi Band 4 includes all-day heart rate and stress monitoring, covering the essential wellness features expected from an everyday fitness tracker.
The Xiaomi Smart Band 11 takes sleep monitoring further with professional sleep management, HRV monitoring and AI-based sleep insights. These additions provide more detailed information about sleeping patterns and related wellness trends. While both devices cover everyday health-tracking requirements, Xiaomi offers a more comprehensive set of sleep-analysis features.
Winner: Xiaomi – Advanced sleep management with HRV monitoring and AI-based insights.
Sports & Training Features
The Redmi Band 4 supports 50 sports modes, making it suitable for users interested in monitoring common workouts and everyday physical activities. Its selection covers the basic requirements of casual fitness enthusiasts.
The Xiaomi Smart Band 11 offers more than 150 sports modes, providing considerably broader activity coverage. This makes it a better option for users who participate in different workouts and want more flexibility when recording their exercise sessions. However, a higher number of sports modes does not automatically guarantee better tracking accuracy or professional training analysis.
Winner: Xiaomi – More than 150 sports modes offer greater workout variety.
Smart Features
The Redmi Band 4 supports message notifications, alarms and multiple watch faces. It also offers WeChat and Alipay QR code payment support in China, although it does not include NFC.
The Xiaomi Smart Band 11 provides a more extensive collection of connected features, including smartphone notifications, music controls, customizable watch faces, contactless payments and smart access cards. NFC functionality is available through its dedicated NFC variant. It also runs Xiaomi HyperOS 4 and supports Android and iOS smartphones.
Winner: Xiaomi – More connected features, music controls and NFC payment support.
Which One Should You Buy?
The Redmi Band 4 is a better choice for budget-conscious buyers who want essential health monitoring, everyday notifications and reliable battery life. Its 50 sports modes and 5ATM water resistance make it suitable for casual fitness tracking.
The Xiaomi Smart Band 11 is worth considering if you want a more feature-rich experience. Its AMOLED display, advanced sleep tracking, HRV monitoring, 150+ sports modes and NFC option offer more versatility. The higher price is justified for users who will actually use these additional features.
Winner: Xiaomi – Better suited to users seeking advanced fitness and smart features.
Final Verdict
Xiaomi Smart Band 11 is the more capable fitness tracker, offering meaningful upgrades in display quality, workout variety, sleep analysis and connectivity. Its larger AMOLED screen and advanced health features make it a stronger everyday companion for active users.
However, the Redmi Band 4 remains an attractive budget option. It covers essential fitness and health-tracking needs while matching Xiaomi’s maximum battery life. At approximately $25, it offers a straightforward experience without requiring buyers to pay for features they might not need.
Winner: Xiaomi – A more complete fitness band, while Redmi remains the better budget alternative.
