How to turn off fast charging on Xiaomi Mi: 5 proven ways

Fast charging is a handy feature that allows you to charge your Xiaomi Mi smartphone in minutes. However, it also has the flip side: accelerated battery wear, overheating of the device and even the risk of sudden shutdown during high loads. If you notice that the battery has become worse, or the phone heats up during charging, you may want to consider turning this feature off.

In this article, we’ll look at all the possible ways to turn off fast charging on Xiaomi devices, from standard MIUI settings to hidden engineering menus, which models support this option, how to check the current charging mode and what to do if standard methods don’t work, and why turning off fast charging can increase battery life by 20-30% when used correctly.

Important: not all methods are suitable for all Xiaomi Mi models. For example, on budget devices like Redmi 9A or Poco M3, there may be no option in settings, and on flagships (Xiaomi 13 Pro, Mi 11 Ultra) there are several options for adjustment, we took these nuances into account and prepared universal solutions.

Why is it worth turning off fast charging on Xiaomi Mi?

Smartphone makers including Xiaomi are pushing fast-charging technology as a key advantage, but independent tests show that the constant use of accelerated charging reduces the life of lithium-ion batteries.

• 🔋 Battery degradation: When you charge fast, the battery heats up more, which speeds up the chemistry inside it.According to a study by Battery University, the temperature is higher than that of the battery. 30°C reduces the battery life by 10-15% for each year of use.
• 🔥 Overheating device: Many owners of Xiaomi Mi 10, Mi 11 Other models complain of heating the body to 40-45°C while charging. This is not only uncomfortable, but potentially dangerous for internal components.
• ⚡ Instable power: In regions with frequent voltage surges, fast charging can cause power controller failures, especially on cheap chargers.
• 📉 Capacity reduction: Through 1-2 During the year of intensive fast charging, many users note the drop in battery capacity to 70-75% from the baseline (normally) 80% after 500 cycle).

Of course, fast charging is convenient when you need to urgently recharge before you go out. But if you charge your phone at night or have time to wait, turning off this feature can significantly extend the life of your Xiaomi Mi.

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use the built-in MIUI options, which is suitable for most modern Xiaomi Mi, Redmi and Poco models based on MIUI 12 and later.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Battery and Performance section.
3. Select Charging (on some firmwares, charging settings may be called).
4. Find the option Fast Charge or Turbo Charge and move the slider to the off position.
5. Confirm the action if a warning appears.

On some devices (e.g. Xiaomi Mi 11 Lite), the option may be elsewhere: Settings → Additional → Charging. If you don’t find an item on the menu, try searching by settings (the magnifier icon in the upper right corner).

⚠️ Attention: On devices with MIUI Global (European firmware) fast charging option may be hidden due to regional restrictions.In this case, try the method with an engineering menu or install it. MIUI China (but note that this may result in loss of warranty).

Method 2: Use of an engineering menu (for advanced users)

If the standard settings do not have the option to turn off fast charging, you can use the hidden engineering menu.This method works on most Xiaomi Mi devices, but requires caution - improper actions can lead to malfunctions of the phone.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information (or Battery Information).
3. Scroll down and find the Fast Charge or Quick Charge.
4. Click on it and select Disable.
5. Restart the device to apply the changes.

On some models (e.g. Xiaomi Mi 9 or Mi 10T), the path may be different. If the ##4636## combination doesn't work, try:

• 📱 ##6484## (test menu) MTK)
• 📱 ##64663## (Qualcomm Engineering Menu)

After you turn off fast charging via the engineering menu, check the charging speed using the AccuBattery or Ampere app. If the charging current has decreased from 3-4A to 1-1.5A, then everything went well.

Method 3: Disconnect via ADB (for power users)

If previous methods have failed, you can use Android Debug Bridge (ADB), a tool for debugging Android devices, which requires a computer and basic command line knowledge.

Step-by-step:

1. Download and install ADB Tools on your computer.
2. On the phone, turn on Developer Mode (go to Settings → About Phone and 7 times click on the MIUI version).
3. Return to Settings → Additional → For developers and enable USB debugging.
4. Connect the phone to your computer and enter:

adb devices

(Your device should appear on the list.)

adb shell settings put global fast_charge 0

Once you've done the command, restart your phone. To get the charge back, use the same command, but with 1 instead of 0.

⚠️ Attention: Misuse of the right ADB Do not enter unknown commands or change other parameters without understanding their purpose. If after turning off fast charging, the phone stopped charging at all, reset through Settings → Reset.

Method 4: Using Third-Party Applications

If you don't want to dig into settings or use ADB, you can use specialized applications that not only turn off fast charging, but also control the current, voltage and temperature of the battery.

Top.-3 Applications for charging management on Xiaomi Mi:

The easiest to use is AccuBattery, which requires no root rights and allows you to track in real time how fast your Xiaomi Mi is charging.

1. Install and open the application.
2. Go to the Charging section.
3. Click on the three dots in the upper right corner and select Limit the charging current.
4. Set the maximum value within 1000-1500 mA (for standard charging).

💡

If the phone charges too slowly (less than 500 mA) after setting the limits, check if the power saving mode is enabled in the MIUI settings.

Method 5: Hardware shutdown (for extreme cases)

If software isn't working, and fast charging is critically damaging to the battery, you can use a hardware solution, which involves using a non-original low-power charger or a special cable.

Options:

• 🔌 Use the charger on the 5V/1A or 5V/2A (Fast charging on Xiaomi usually requires an old smartphone. 9V/2A or 12V/1.5A, So a weak RAM will automatically bring the phone back to standard mode.
• 🔗 Buy a current-restricted cable (for example, USB-C to USB-A without Quick Charge support, such cables block the fast charging protocol.
• 🔋 Use power bank without Quick Charge support (most budget models charge your phone in standard mode).

The downside of this method is slow charging (by 2-3 times longer than usual), but it 100% guarantees to turn off fast charging without interference with the software. This option is often used by owners of Xiaomi Mi A1/A2 (Android One), where there is no option to turn off in the settings.

💡

Hardware-to-drive fast charging is the only way that works on all Xiaomi models, including the oldest.However, it requires the purchase of additional accessories and is inconvenient for daily use.

How to check that fast charging is actually turned off?

Turning off fast charging is half the battle, making sure the changes are in place.

1. Use the Ampere app: It shows the charging current in real time. With fast charging, the values are usually 2000-4000 mA, with a standard one, 500-1500 mA.
2. Heating: When charging normally, the phone should stay cool or slightly warm. If it's warming, fast charging is still active.

If after all the manipulations the charging current remains high, try:

• 🔄 Reboot the phone.
• 🔌 Connect another charger.
• 📱 Reset the settings to factory (pre-return backup!).
