How to enable reverse charging on Xiaomi: the complete guide

Reversible charging (or reverse wireless charging) is one of the most useful features of modern Xiaomi smartphones, which allows you to use the device as a wireless charging station for other gadgets. It can quickly recharge headphones, smartwatches or even another smartphone without having an outlet at hand. However, many users face difficulties when first turning on this option: somewhere the function is hidden in the settings, somewhere requires additional activation, and some models do not have it in the standard firmware.

In this article, we will learn how to turn reverse charging on Xiaomi, Redmi and POCO smartphones, which models support this technology, and what to do if the option is inactive. You will also learn about the nuances of security, charging speed and alternative ways to activate the function on informal firmware. If your phone supports Qi-standard, but reverse charging does not work, here you will find a solution.

What Xiaomi models support reverse charging

Not all Xiaomi smartphones feature a reverse charge feature, which is available mainly on flagship and some mid-budget models with support for Qi wireless charging. Here is the current list of devices where the function works exactly:

• 📱 Xiaomi 13 Pro, Xiaomi 13 Ultra – up to 10 W in reverse charging mode
• 📱 Xiaomi 12 Pro, Xiaomi 12S Ultra – Qi 1.2.4 support and reverse charging up to 7.5W
• 📱 Xiaomi Mix 4, Xiaomi Mix Fold 2/3 — function is available, but speed is limited 5 Watt
• 📱 Redmi K50 Pro, Redmi K60 Pro – reverse charging up to 5W (requires an update) MIUI)
• 📱 POCO F5 Pro – support for the function based on Redmi K60

Important: Even if your model is on the list, the feature can be blocked in some regional firmware versions.For example, on the Xiaomi 12T Pro for the European market, reverse charging is disabled by default and requires manual activation via ADB.

On models with a Snapdragon 8 Gen 2 processor (such as the Xiaomi 13 or Redmi K60 Pro), reverse charging can automatically turn off when overheating above 45°C. If your phone gets very hot while using the feature, try removing the case or reducing the load on the processor.

How to turn on reverse charging in MIUI settings

If your model officially supports the function, you can activate it directly in the settings menu.

1. Open the Settings app on your smartphone.
2. Go to Battery and Performance (on some models – Battery).
3. Select Wireless Charging or Reverse Charging (the name may vary depending on the version of MIUI).
4. Activate the Reverse Charging or Reverse Wireless Charging switch.
5. Confirm the activation of the function if a battery consumption warning appears.

After activation, put a compatible device on the back of the smartphone (for example, Xiaomi Watch S3 or Redmi Buds 4 Pro). Charging will begin automatically if the gadget supports the Qi standard. A notification will appear on the screen with the current power and charge level of the connected device.

Make sure the main smartphone has a charge level of > 20%

Remove the cover (if it is thicker than 2 mm)

Check the compatibility of the charger with Qi

Disable energy-intensive applications (games, video editing)

⚠️ Note: On some models (e.g, POCO F5) Reverse charging only works when the power source is connected to the main smartphone, so your Xiaomi must charge itself from the outlet to give power to another device.

Activation of reverse charging via ADB (for hidden functions)

If your smartphone does not have the option “Reverse Charging” in its settings, but the model officially supports the function (see table above), it can be enabled via the following link: ADB-This method works on most Snapdragon processors. 888/8 Gen 1/8 Gen 2 and requires a computer with drivers installed ADB.

Instructions:

1. Turn on Developer Mode on your smartphone: go to Settings → About Phone → MIUI version and press 7 times on the build number.
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect your phone to your PC through USB-Cable (original!) and confirm the debugging permission.
4. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell settings put global wireless_reverse_charge_enabled 1

After you complete the command, restart your smartphone. "Reverse Charging" should appear in the battery settings. If the function is still inactive, try an alternative command:

adb shell am broadcast -a android.intent.action.WIRELESS_REVERSE_CHARGE --ez enabled true

Important: On some firmware (e.g. MIUI EU), these commands may not work due to regional limitations, in which case only re-flashing to a global or Chinese version of MIUI will help.

Charging speed and compatible devices

The maximum power of reverse charging depends on the model of the smartphone and the gadget being charged.

• 🔋 Xiaomi 13 Ultra gives up 10 But the real speed for the AirPods Pro will be ~3-4 Watt.
• 🔋 Redmi K60 Pro limited to 5 watts, which is only enough for slow charging of watches or headphones.
• 🔋 Headphones Xiaomi Buds 4 Pro charges faster (up to) 5 Wh) than Samsung Galaxy Buds (2-3 Watt).

For comparison, the standard wired charging of the same AirPods gives 5-7 watts, so the reverse method is convenient only in emergency cases. Also consider that simultaneous charging of the main smartphone and connected gadget reduces the speed for both devices by 30-40%.

⚠️ Note: Do not use reverse charging for smartphones with a battery capacity of more than 4000 mAh (for example, iPhone 14 Pro Max or Samsung Galaxy). S23 This can cause overheating and automatically shutting down the feature on your Xiaomi.

Frequent problems and their solutions

If reverse charging doesn’t work, here are the most common reasons and ways to fix them:

• 🔄 Function gray and inactive → Check if the smartphone is connected to charging (some models require external power supply).
• 🔥 The phone overheats and turns off charging → Remove the case, reduce the brightness of the screen and close the background applications.
• ⚡ Device not detectable. → Check compatibility with Qi (some gadgets require magnetic fastening).
• 📉 Charging speed too low → Try restarting your smartphone or updating it. MIUI last-minute.

If the problem persists, reset the wireless module settings:

1. Go to Settings → Connections and Sharing → Reset network settings.
2. Select Reset Bluetooth and Wi-Fi settings (this will also reset NFC and Qi settings).
3. Restart the device and try to turn on reverse charging again.

💡

If your Xiaomi doesn’t support reverse charging, but there is Qi wireless charging, you can use an external adapter (such as the Xiaomi Wireless Charging Board) to recharge other devices.

Safety and recommendations for use

Reverse charging is a convenient feature, but frequent use can have a negative impact on your smartphone battery.

• 🛡️ Do not use the function at a charge level below 20% – this accelerates battery wear.
• ❄️ Avoid overheating – if the body is heated higher 40°C, take a break for me. 10-15 minute.
• 🔋 Do not charge devices with damaged batteries (blown or deformed).
• 📵 Turn off reverse charging after use to avoid parasitic energy consumption.

According to research, regular use of reverse charging reduces battery life by 5-10% faster than conventional wired charging. If you often recharge other gadgets, consider buying a portable power bank with support for Qi - this is a gentle option for a basic smartphone.

💡

Reversible charging is an emergency solution, not a permanent power supply, and it's better to have a separate wireless charging system for daily use.
