Modern smartphones have become universal health monitoring tools, and Xiaomi Redmi 9 is no exception. Built-in motion sensors allow you to keep records of physical activity without having to buy expensive fitness bracelets. However, out of the box, the device often does not provide the full picture, requiring the user to correctly initial configuration of the software environment. Without proper setting, data can be inaccurate, and the battery will be wasted on background processes.
In this article, we will discuss how to turn your phone into a reliable trainer, and we will discuss calibration, choosing the right apps, and optimizing Android system settings for a stable step counter, understanding these nuances will help you get the most accurate data about distance traveled and calories burned.
It's worth noting that the MIUI ecosystem has its own background-processing features. An aggressive energy-saving system can prematurely shut down activity tracking applications unless you set exceptions, so setting up a pedometer is not just about installing a program, it's about working with the device's permissions and sensors.
Selecting the right application for activity tracking
The first step towards accurate accounting of steps is the choice of software. Xiaomi Redmi 9 preinstalled its own service Mi Fitness (formerly known as Mi Sport), which is deeply integrated into the shell of MIUI. This application uses the system sensors of the accelerometer and gyroscope, ensuring minimal energy consumption compared to third-party counterparts. For most users, this option is the optimal start.
However, if you want more advanced statistics, social media syncs, or integration with other smart devices, it’s worth considering alternatives, with Google Fit and Samsung Health (available via APK) both of which have powerful data analytics algorithms.

Not using.
When choosing software, pay attention to the presence of desktop widgets. Visualizing progress right on the lock screen or the main menu motivates you to take more steps daily. The application interface should be clear, and data synchronization should occur without delay. For Redmi 9 with its IPS LCD screen, font clarity and interface contrast play an important role when used in bright sun.
💡
If you use a third-party app, be sure to give it permission to auto-start, otherwise the MIUI system can kill the process after unlocking the screen.
Mi Fitness setup on Redmi 9
To activate the built-in tracker, you need to find the Mi Fitness app in the Tools folder or search. When you first start, the system will request access to location and physical activity data. Without granting these rights, the counting algorithm will not work, and you will need authorization in Mi Account, which is necessary to store statistics in the cloud.
Then you have to set up a user profile, and you have to enter the actual weight, height and age data, and these parameters are critical to calculating the length of a step and, as a result, to accurately determine the distance traveled, and if you type in the wrong data, the phone will count the steps correctly, but the mileage and the number of calories burned will be severely distorted.
In the app settings section, look for the “Steps Goal” item. The standard value is usually 10,000 steps, but you can change it to suit your current level of training. For beginners of Redmi 9, it is recommended to set realistic goals, gradually increasing the load, and you can also turn on audible notifications when you achieve intermediate results.
⚠️ Attention: Don't set a daily goal too high right after setting up.A sharp increase in load can lead to injury or a quick burnout of motivation.Start with 5000-6000 stepping-step.
Calibration of sensors and increase accuracy
Even the most advanced accelerometer requires calibration to work properly. In the Xiaomi Redmi 9, this process is often automatic, but in some cases, manual intervention is required. If you notice that the phone is not responding to movement or, conversely, has steps when you just sit, you need to calibrate.
You can use the engineering menu or third-party utilities from Google Play, such as “GPS Status & Toolbox.” However, the safest method is to use built-in diagnostics. Go to the About Phone menu and click on the MIUI version several times to activate additional options, then search for the hardware testing section.
There's an easy way to train a pedometer to walk: walk a known distance, like 100 meters, from a stadium marking or a map. Compare your phone to a real distance. If the error is high, try resetting your fitness data in the app settings and start measuring again with your phone in your pocket instead of your hand.
How does the accelerometer work in Redmi 9?
The microelectromechanical system (MEMS) is at the core of this work, and it responds to a change in acceleration, and when you step, the phone experiences a characteristic vibration and a change in position in space. The algorithm analyzes the frequency and amplitude of these oscillations, sifting out extraneous movements, such as shaking in transport.> Optimizing energy saving for background work One of the main problems Xiaomi owners have is an aggressive memory management policy.The system can complete the pedometer process to save charge, especially if the screen is off for a long time. In order for the pedometer to work continuously, you need to add the app to the exception list. This is a critical stage in the setup. → Battery and performance. Find your step app (like Mi Fitness) in the list and select No Limits mode». This will allow the application to run in the background without interruptions. It is also recommended to enable autorun for this service. additionally check the notification settings. Make sure that the application allows notifications to be displayed on the lock screen. This will allow you to see the current progress without unlocking the phone. MIUI also has the Advanced Settings feature in the battery menu, where you can turn off sleep mode for selected applications. Settings Path in menu Recommended value Battery Impact AutoRun Settings → Applications → AutoRun Minimum Battery Mode Settings → Battery Mode → Battery Mode → No Limits Average Settings Notifications → Notification Center Allowed No Access to Data Settings → Apps → Permissions Always Low Synchronization with Google Fit and Third-Party Services Many users prefer a single Google ecosystem. Fortunately, Mi Fitness supports synchronization with Google Fit. This allows you to combine data from other devices, such as Fit, Fit, Fit, in one activity resolution, and read the application, “When connecting to the application, and making sure you have a link to the application.” Two-way synchronization can lead to duplication of steps (for example, the phone counted 1000, the clock was 1000, and eventually became 2000), so it is better to prioritize one source. If you use specialized running services like Strava or Runkeeper, check for integration with Mi Fitness. It is often easier to sync a third-party app with Google Fit, and Mi Fitness will transfer basic data there. This creates a reliable information chain without losing statistics. ⚠️ Attention: When synchronizing multiple data sources, conflicts may arise. If you see a sharp jump in statistics, try temporarily disabling sync with one of the services and clearing the application cache. Sometimes users are faced with a situation where the pedometer stops responding to movements. First of all, check if the motion sensor in the system is disabled. On Redmi 9, this is rare, but after updating the firmware, the settings may get lost. Try rebooting your device, which solves 80% of software failures. If the problem persists, check for updates for the Mi Fitness app itself through the GetApps store or Google Play. An outdated version may not work properly with new versions of Android. It's also worth checking if the proximity sensor or the accelerometer is sealed with a tight case, although mechanical sensors are rarely affected by cases. In extreme cases, you can reset the application data. Go to Settings → Annexes → Mi Fitness → Memory and click "Clear Data». This will return the application to a state immediately after installation, and you will need to reconfigure the profile, but often this restores the meter to work (FAQ) Does the pedometer work affect the Redmi battery discharge rate? 9? The step counting itself consumes minimal energy, because low-frequency sensor interrupts are used. The main flow goes to the screen and constant operation. GPS, If it's on for route tracking, the pedometer will add no more than that. 1-2% Will the pedometer work if the phone is in a bag or a backpack? Yes, Xiaomi Redmi accelerometer. 9 It can even record steps through the fabric and leather, but the accuracy can be slightly lower than when you wear pants in your pocket, because the phone's motion is less amplitude relative to the center of gravity of the body? The basic step and distance count is completely offline. The Internet is only required to set up your account first, sync data to the cloud, and get map information to track your routes in real time. Why do pedometer data reset after you restart? This can happen because of a synchronization failure or if the application is not authorized to autostart. Make sure that the battery settings for Mi Fitness select "No restrictions" and the autorun app is enabled.
