💡

If after activating fast charging the phone is very warm, try to remove the case - this will improve heat sink and prevent power throttling.

How to Check Real Charging Speed on Xiaomi

To make sure that fast charging actually works, you need to measure the current power, and you can do this in a number of ways:

Method 1: through the built-in menu

On some models (e.g. Xiaomi) 12T or POCO F4 GT) The charging speed is displayed right on the lock screen. Connect the charger and look at the indicator next to the battery icon — it should say Fast Charging or XXW (where XX — current-power).

Method 2: Using the AccuBattery application

AccuBattery (available on Google Play) shows the current charging speed in real time, as well as the battery temperature and wear.

1. Connect the phone to the charger.
2. Open the application and go to the Charging tab.
3. Note the Power (W) chart if the value exceeds 10W, fast-charging works.

Method 3: through ADB-Teams (for technical users)

If you know me, ADB, Charging data can be obtained directly from the system:

adb shell dumpsys battery

In the conclusion, find the lines:

• AC Powered: True (Phone Connected to Network)
• charge counter: XXXX (current-charge)
• voltage: XXX (tension)
• temperature: XX (battery)

To calculate power, multiply voltage by current (for example, 5V × 3A = 15W).

⚠️ Note: If the test power does not exceed 10W, despite activation of the function, check: 🔌 Cable and charger for damage. 📱 Phone temperature (when overheating, the speed drops). 🔄 Firmware version (update) MIUI until the last stable version).
