Introduction: wireless charging capabilities in Xiaomi 12 Pro
Xiaomi 12 Pro is the flagship smartphone of 2022, which supports wireless charging capacity up to 50 watts. This feature allows you to charge the device without connecting a cable using special charging stations. However, many users are faced with the question: how to properly activate and configure this option to keep it stable and safe.
Unlike wired charging, where you just need to plug in a cable, wireless technology requires a few conditions to be met. In this article, we'll look at step-by-step instructions for switching on, compatible accessories, and common errors that can interfere with the function. We'll focus on MIUI settings, because the firmware version depends on the availability of certain parameters.
If you’ve just purchased the Xiaomi 12 Pro or are planning to use wireless charging for the first time, this guide will help you avoid common problems, such as why your smartphone doesn’t start charging when you’re stationed or why the charging speed is lower than it was claimed, and how to check your charging pad’s compatibility with the model.
Requirements for wireless charging: what you need to know before you start
Before you turn on wireless charging, make sure your Xiaomi 12 Pro and accessories meet the minimum requirements.
- 🔋 Firmware version: the function works on MIUI 13 and later: Older versions may not have optimization settings.
- 🔌 Compatible charging station: Qi standard support required (minimum 10W, recommended 30W and higher for fast charging).
- 📱 Case condition: thick covers (especially metallized ones) can block the signal; the optimal is to use thin silicone or without a cover.
- 🔄 Temperature: When overheated, the smartphone automatically reduces the charging power. Avoid direct sunlight.
Important: Xiaomi 12 Pro supports reverse wireless charging (for accessories like Mi Band or headphones), but it needs to be turned on separately. This option is available in the Settings → Battery menu and requires at least 20% of the main battery charge.
💡
If you’re using a charging station from another manufacturer (such as Samsung or Apple), check its Qi certification. Uncertified devices can charge the Xiaomi 12 Pro at a speed of just 5 watts, even if they support high power.
Step-by-step: how to turn on wireless charging
In most cases, the Xiaomi 12 Pro will automatically activate charging when placed at a compatible station, but for optimal performance, the following steps are recommended:
- Check the battery level. If it is below 5%, the smartphone may not start charging — first connect the wired adapter for 10-15 minutes.
- Place your smartphone in the center of the charging pad, even a slight shift can cause a charging interruption, and some stations have backlights or a beep to confirm the correct position.
- Open Settings → Battery → Wireless charging. Here you can turn on the option of Fast wireless charging (if it is turned off).
- Activate Optimized Charging (if required) This feature extends battery life by limiting charge to 80% on long-term connections (e.g., at night).
If the smartphone does not respond to the charging station:
- 🔄 Reset the device.
- 🔌 Try another socket or power adapter for the station.
- 📱 Make sure that your smartphone doesn’t have any active processes that consume a lot of energy (such as video editing or gaming).

Safety and care: how to extend battery life
Wireless charging is convenient, but if used improperly, it can reduce battery life.
- 🔋 Avoid full discharge. Connect your smartphone to charging at 15-20% charge.
- 🌡️ Do not leave the device at the station longer than necessary. After 100% turn off the power or activate Optimized charging.
- ☀️ Do not charge your smartphone in direct sunlight or in a stuffy room.
- 🔄 Once every 2-3 months, perform battery calibration: completely discharge and charge the device to 100% without interruptions.
To monitor battery status, use the built-in Settings → Battery → Battery Status menu, which displays the charging cycle (optimally up to 500 cycles) and current capacity. If the value has dropped below 80% of the original, consider replacing the battery at the service center.
⚠️ Warning: Using unoriginal charging stations with unstable voltage can cause the battery to bloat. At the first sign of deformation of the case (for example, the screen has begun to "go away") immediately turn off the smartphone and contact the service.
