Xiaomi has been the budget fitness tracker king for years, and in 2025, that reign continues with the release of the Xiaomi Smart Band 9. Leveraging the best of its ancestors, the Band 9 introduces a bigger AMOLED screen, improved performance, more precise sensors, and better battery life — all at an aggressively low price tag that beats out many of its competitors.
While smartwatches such as the Galaxy Watch or Apple Watch get all the headlines, fitness trackers such as the Xiaomi Smart Band 9 appeal to those who desire simplicity, concentration, and extended usage without requiring a recharge of their wearable each night. For those seeking health and fitness fundamentals monitoring without the cost and overhead of a full smartwatch, the Smart Band 9 provides extraordinary value.
Whether you’re a student, a casual walker, a gym-goer, or someone entering the world of wearables for the first time, the Xiaomi Smart Band 9 makes a strong case to be your go-to daily companion.
Refined Design with a Familiar Feel
The Xiaomi Smart Band 9 does not break fresh ground with design but refines it to perfection. The band keeps its pill-shaped module that sits comfortably in a flexible TPU strap. The body is super light and now features a matte aluminum alloy casing that feels more premium on the wrist. Its ergonomic curve allows a secure fit for all-day wear, even when sleeping or exercising.
This year, Xiaomi launched a stronger strap locking system and four new strap colors — Midnight Black, Electric Blue, Coral Orange, and Classic White. Smart Band 9 is also 5ATM water-resistant and can be used for showering, swimming, and working out in the gym.
Though still thin and slender, the Band 9 has slightly thinner bezels and nearly edge-to-edge screen styling to make it appear more streamlined than previous models.
A Larger and Improved AMOLED Screen
The Smart Band 9 boasts a new 1.62-inch AMOLED screen, which is brighter, smoother to view, and more readable in sunlight than the Band 8. The resolution has been upgraded, presenting sharper text and icons. Xiaomi boosted the peak brightness to 600 nits, which proves to be a big help if you are outside.
A significant upgrade is the inclusion of Always-On Display (AOD) support for some watch faces. It’s optional, naturally, if you want to conserve battery, but if you’re looking for that more watch-like experience, AOD is a nice touch. The UI has also been updated to allow for smoother transition and more animated watch faces and customizable widgets.
Navigation is easy, with gesture-based swipes for notifications, widgets, workout monitoring, and settings — all working in perfect harmony without the slightest lag or stutter due to a newer internal chip and firmware.
Performance and App Experience
Xiaomi has enhanced the performance engine within the Band 9, so it is quicker at responding to touch, launching apps, and switching between menus. It is not a full-fledged smartwatch OS, of course, but for what it is doing — monitoring fitness, displaying notifications, and serving up basic apps — it is responsive and solid.
The Mi Fitness app (formerly Xiaomi Wear) remains the primary companion on Android and iOS. It has been redesigned to include improved chart visualization, weekly fitness reports, and simplified band interface customization.
The Bluetooth 5.3 provides more solid, quicker pairing with your phone. All apps’ notifications, caller ID, and quick replies for Android users are supported by the Band 9. Although there is no speaker or mic, the Band 9 serves well as a quiet companion that vibrates your wrist if a message or call arrives.
Health Tracking Accuracy
Xiaomi’s health tracking technology has made steady progress over the years, and the Band 9 represents one of the most refined efforts yet. It features a new-generation PPG heart rate sensor for real-time monitoring, including high and low heart rate alerts.
The SpO2 sensor now has continuous blood oxygen monitoring capability, which was available only in more expensive devices. Sleep tracking features have thorough descriptions of deep sleep, light sleep, REM cycles, and even nap tracking throughout the day. Stress monitoring is also available on the Band 9, based on heart rate variability as an estimate of mental fatigue and anxiety.
Women’s health monitoring is integrated, including menstrual cycle recording and period prediction. Skin temperature monitoring for sleep tracking was also added by Xiaomi, though this is observational rather than diagnostic in nature.
All in all, though it won’t match medical-grade accuracy, the Band 9’s health monitoring features are precise enough for the majority of casual and intermediate users — providing daily feedback and trends to assist with lifestyle adjustments.
Workout and Activity Features
Xiaomi has also added more than 150 workout modes to the fitness tracking arsenal of the Band 9, including walking, cycling, and swimming as well as more intense sports such as boxing, HIIT, and weightlifting. The tracker automatically recognizes common activities such as running, treadmill work, or fast walking and records them accordingly.
There is no GPS built in, but it can access your phone’s GPS to track distance and routes while running or cycling outdoors. Real-time stats on the screen in a workout include time, distance, calories, pace, heart rate zones, etc.
The training load summary provides you with a general overview of how hard your week-long workouts have been, and the goal streak system motivates daily activity and step goals through gamified badges of progress.
Guided breathing exercises and movement reminders have also been added by Xiaomi to enable users to tackle sedentary behavior during work or study time.
Battery Life That Just Doesn’t Quit
Battery life is one of the most remarkable features of the Smart Band 9. Even with the larger, brighter screen and Always-On capabilities, it still manages up to 14 days of use in normal conditions. Under heavier usage, such as continuous SpO2 and heart rate tracking, you can easily get 8 to 10 days.
The bundled magnetic charger snaps on securely and charges the band 0-100 percent in less than 80 minutes. There is a power-saving mode that allows you to conserve battery life even more by turning off animations and background tracking.
For under $100, this stamina is amazing and far surpasses most smartwatches and even some more expensive fitness bands.
Smart Features and Ecosystem Integration
Band 9 has the essential smart features to add its value without making it overly complicated to use. You get app messages, call alerts, play control of music, weather forecast, alarm clock, stopwatch, and a phone finder function.
There is no NFC or payment support in the international variant, but a Band 9 NFC version is sold in some Asian and European countries for contactless payments with Xiaomi Pay.
The tracker is compatible with both Android and iOS, though Android users have a greater access to smart reply choices and direct call ignoring features. The app also provides custom widget ability, activity goal setting, and health data management.
You can connect Band 9 data to third-party apps such as Google Fit and Strava, but the integration is smoother in Android than in iOS.

Final Verdict
The Xiaomi Smart Band 9 is yet another proof point that Xiaomi knows how to dominate the budget fitness space. It doesn’t pretend to be a smartwatch, and it doesn’t need to be. It’s a fitness band — but a very smart, well-rounded, and stylish one.
For a price that’s usually half or even a third of the competition, the Band 9 provides a bright screen, week-long battery life, accurate sleep and health tracking, and an easy-to-use app ecosystem. It does all the fitness fundamentals, throws in smart elements where it counts, and avoids the gimmicks.
If you desire dependable tracking, low charging, and complete Android-and-iOS compatibility — at a price that won’t hurt — the Xiaomi Smart Band 9 is the uncompromising best. It builds on the tradition of the Mi Band series as the best budget-friendly wearable available, and it’s a must-have for anyone prioritizing pragmatism over prestige.
