The Health app on Xiaomi Redmi 9: a full guide to features and settings

Xiaomi Redmi 9 has a Health app that many users either ignore or delete without realizing it’s real. At first glance, it’s just a pedometer, but in fact, it’s a full-fledged fitness tracker with the integration of medical sensors, Mi Band smartwatches and even sleep analytics. In this article, we’ll discuss why this app is needed, how it interacts with the Redmi 9 hardware, and why it should be left on the system — even if you’re not an athlete.

The Redmi 9 is a model that, despite its budget price, has an accelerometer and gyroscope sensor that uses the Health app to track activity, but without the right setup, it can work incorrectly, such as overstating steps or not recording sleep, and we'll show you how to avoid the typical mistakes and unlock the potential of the program.

What is the Health App and Why You Need It on Redmi 9?

The Health app (com.mi.health) is a proprietary service from Xiaomi that combines data from smartphone sensors and external devices (such as the Mi Band 5/6 or Xiaomi Smart Scale).

On Redmi 9, the app is paired with a motion sensor (BMI160) that is built into the MediaTek Helio G35 chipset, which allows you to record activity even without a smartwatch, although the accuracy will be lower. For example, a pedometer in a phone can be 10-15% wrong due to the lack of a specialized sensor (as in the Mi Band).

Important: the app doesn't replace medical devices, but it helps you track your dynamics, for example, if you start running, it will show you progress in distance and heart rate (when synchronized with the Mi Band).

How Health App Interacts with Redmi 9 Sensors

In Redmi 9, three key components are responsible for the application:

1. Accelerometer - fixes the acceleration of the phone (steps, shakes).
2. Gyroscope – determines the orientation in space (useful for running / cycling).
3. Illumination sensor – indirectly affects the analysis of sleep (determines the time of falling asleep by darkening the screen).

The app uses a combination of these to calculate activity, such as when you walk, the accelerometer records rhythmic movements, and the gyroscope helps distinguish walking from driving.

• 🚶 False positives: Your phone can count steps if you just shake it in your hands.
• 🛌 Mi Band-free sleep: The app determines sleep by time of inactivity, not by physiological data.
• 🔋 Increased battery consumption: constant operation of sensors adds ~5-7% to the daily rate.

To reduce the margins, Xiaomi has added machine learning algorithms, such as learning from your habits: if you go to work at the same time every day, it begins to distinguish walking from taking the subway.

Step-by-step setting up the Health app on Redmi 9

By default, the app is on, but it works in minimal mode. To unlock its potential, follow these steps:

1. Open the app (a red heart icon).
2. Fill out the profile: specify height, weight, age – this is necessary to calculate calories.
3. Connect devices (if any): Profile → Devices → Add.
4. Set goals: Set the desired number of steps (standard – 6000).
5. Enable notifications: Settings → Notifications → Enable alerts.

For accurate sleep tracking:

• 📵 Put the phone next to the bed (no more than 1 meter).
• 🔕 Turn on the mode Do not disturb during sleep.
• 🌙 Set the time of day off and wake up manually (Sleep) → Settings).

Activate high-precision mode in Settings → Data Accuracy

Calibrate the pedometer (walk 20 steps with your phone in your hand)

Connect to Mi Band (if applicable)

Turn off battery optimization for the application in Settings → Battery → Optimization

Note: If you use two of these SIM-maps, the application may conflict with the operator's services (for example, MTS Health). SIM-map.

Synchronization with Mi Band and other devices

The Health app is really useful when you plug in the Mi Band or other Xiaomi gadgets. Here's how to do it:

1. Open the application and go to Profile → Devices.
2. Click Add Device and select a model (e.g. Mi Band 6).
3. Follow the instructions on the screen (turn on Bluetooth, confirm pairing).

Once connected, the data from the bracelet will automatically sync with the smartphone.

Important: If the data is not synchronized after connecting the Mi Band, check the firmware version of the bracelet. For stable operation, you need MIUI 12.5+ on the phone and the latest version of firmware on the Mi Band.

1. Reboot the phone and bracelet.

2. Remove the device from the list and connect again.

3. Update the Health app via Google Play.-->

Common Problems and Their Solutions

Redmi 9 users often encounter typical app bugs, and here are the most common ways to fix them:

• 🔄 No updates: Check your internet connection (the app needs Xiaomi servers to sync). Clear the cache: Settings → Annexes → Health → Memory. → Clear the cache.
• 🚶 Higher step count: Calibrate the pedometer: walk 100 steps with your phone in your pocket, compare it to the real number. Turn off the steps in other apps (Google Fit, Samsung Health).
• 🔋 Strong battery consumption: Turn off background activity: Settings → Battery → Optimization → Health → No restrictions. Reduce the synchronization frequency in the application settings.

Warning: If the app stopped working after the MIUI update, try to roll back to the previous version via APKMirror.Some MIUI 13 builds have sensor bugs.

💡

Before resetting your phone, be sure to export your data from the Health app to the file (Profile → Data Export) and can be recovered after resetting.

Hidden functions of the Health app

Few people know, but the app has useful features that are not visible at first glance:

• 📈 Export of data to CSV: You can analyze activity in Excel. → Settings → Export of data.
• 🏃 Non-exercise GPS: the application can count calories when running on a treadmill (enable the closed room mode).
• 🩺 Water Reminders: Configured in Profile → Reminders (interval and volume).
• 📱 Widget to the main screen: add through a long press on the desktop → Widgets → Health.

Another hidden possibility is the older person mode, where if you put your 60+ profile on it, the app will give you more gentle activity recommendations and more frequent reminders of breaks.

For statisticians, there are weekly reports comparing your activity to your age-group averages. To see them, go to Statistics → Week.

Alternatives to the standard Health App

If you are not satisfied with the functionality of the native application, you can use third-party services:

However, the standard Xiaomi app has one key advantage: it is optimized for the Redmi 9 sensors and consumes less battery than its counterparts. If you only need basic statistics (steps, sleep), it is better to leave the native solution.
