If the screen goes off too quickly after activation of the protection, try turning off the screen. AOD or add the Settings app to the battery optimization exceptions.

Optimizing battery charging for longevity (Health Charging)

One of the most useful features of Health mode is the optimization of battery charging (Health Charging), which limits battery power to the maximum of the battery. 80-90%, And this is a huge reduction in battery wear, and research has shown that lithium-ion batteries lose capacity the fastest when they're charged higher. 80% lower 20%. Health Charging helps to avoid this.

To enable charging optimization on Xiaomi smartphones:

1. Go to Settings → Battery and Performance.
2. Select Battery Settings → Charging Optimization.
3. Activate the slider Enable charging optimization.
4. Set a charge limit (80 percent is recommended for maximum service life).

On the Xiaomi Watch 2 Pro and the Mi Band 8 fitness bracelets, this feature is called Smart Charging and is enabled via the Mi Fitness app:

1. Open Mi Fitness and select your device.
2. Go to the Device Settings → Battery.

• 🔹 Make sure the time on the device is set correctly (automatic time zone determination can knock the schedule down).
• 🔹 Reboot your smartphone – sometimes it helps to reset the hanging processes.

2.Mi Band sleep data is not shown correctly

• 🔹 Check if the bracelet fits tightly to the wrist (should be tightened but not overpress blood vessels).
• 🔹 Turn off the flight mode on the bracelet before bedtime (it can block data collection).
• 🔹 Update the bracelet firmware through Mi Fitness.

3. Charging optimization doesn't work on a smartphone

• 🔹 Make sure you use the original cable and power supply (some unoriginal charging ignores Xiaomi's limitations).
• 🔹 Check if the game mode is enabled (Settings) → Special facilities → Game mode – it can cancel charging restrictions.
• 🔹 Reset the battery settings (Settings) → Battery → Additionally. → Resetting battery settings).

4.Pulse sensor on Xiaomi Watch shows unrealistic values

• 🔹 Wipe the sensor and skin with an alcohol tampon (fat and sweat interfere with reading).
