How to disable fast charging on Xiaomi smartphones: all the ways and nuances

The fast-charging feature has become standard for most modern Xiaomi smartphones, including the Redmi line, POCO and the flagship Mi/Xiaomi 13/14 models. It allows you to recover up to 50-70% of battery power in 30-40 minutes, which is extremely convenient in everyday use. However, this technology has a downside: accelerated battery wear, overheating of the device and the potential risks when using non-original chargers.

Some users prefer to turn off fast charging to extend battery life or solve overheating problems. But how to do it right? In this article, we will examine all the available methods, from standard MIUI settings to hidden options of the engineering menu, and you will learn which Xiaomi models support this feature, and what the consequences of turning it off for different types of batteries.

Important: The procedure may vary depending on the firmware version (MIUI 12, 13, 14 or HyperOS) and the smartphone model. If your device does not support manually turning off fast charging via the menu, you will have to use alternative methods, which we will also discuss.

1.What Xiaomi models support fast charging shutdown?

Not all Xiaomi smartphones allow you to manually deactivate the accelerated charging function, depending on the firmware version and hardware platform.

✅ Supports shutdown through settings (starting with MIUI 12):

• 📱 Flagship series: Xiaomi 11/12/13/14, Mi 10/10T/10 Pro, Mix 4/Fold
• 📱 Mid-segment: Redmi Note 10/11/12 Pro, POCO F3/F4/F5, Xiaomi Civi
• 📱 Budget models (limited): Redmi 10/12C, POCO M4/M5 (only on some firmware)

❌ Do not support manual shutdown (requires an engineering menu or third-party utilities):

• 🔋 Old models: Redmi 9/9A, POCO X3 NFC, Mi 9/9T
• 🔋 Devices with proprietary protocols: Xiaomi 11T Pro (120W Charging), Black Shark (Gaming Smartphones)

How do you know your model? Go to Settings → About Phone → Model. If your device isn’t in the list above, try the methods in the following sections — one of them will work.

2. Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use the built-in firmware options, which works on most modern Xiaomi devices with MIUI 12 and later.

Step-by-step:

1. Open Settings (the gear icon on the main screen).
2. Go to the Battery and Performance section.
3. Select Charging (or Charging Settings on some models).
4. Find the Quick Charge option (can be called Turbo Charge or Quick Charge).
5. Switch the slider to the off position.

⚠️

Attention! On some devices (e.g. Redmi Note 11 Pro+), the option is hidden behind the optional menu. If you don't see "Fast Charge", tap three dots in the upper right corner of the screen and select Additional settings.

After the fast charge is turned off, the smartphone will charge at standard power (usually 5W-10W), which can increase the full charge time to 3-4 hours.

Connect the original charger|Check the battery temperature (should be) < 40°C)|Close all active applications|Make sure the charge level is > 20%-->

Method 2: Engineering menu (for advanced users)

If the settings do not have the option to turn off, you can use the Engineering Mode, which requires caution, since incorrect actions can lead to malfunctions of the device.

Instructions:

1. Open the Phone app and type in the combination: ##4636## Some models may require code ##6484## or ##64663##.
2. In the menu that opens, select MTK Settings (for MediaTek chips) or Qualcomm Settings (for Snapdragon).
3. Go to Battery or Charging section.
4. Find the Fast Charge or Quick Charge settings and turn them off.
5. Save the changes and restart the device.

⚠️

Attention! On devices with HyperOS (the new firmware Xiaomi) the engineering menu may be blocked. ADB-Also, do not change other parameters in the engineering menu, this can disrupt the stability of the system.

If after disconnecting the smartphone stopped charging at all, return the settings to the original state or reset through Settings → System → Reset settings.

💡

Before entering the engineering menu, back up your data via Settings → Memory → Backup. This will help restore the system in the event of a failure.

Method 3: Disconnect via ADB (for power users)

The Android Debug Bridge (ADB) method is suitable for devices where fast charging is not disabled through standard settings. You will need a computer with Xiaomi drivers installed and USB debugging enabled.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI until the notification "You've become a developer" appears.

USB debugging

Settings → Additional → For Developers

Connect your smartphone to your PC and confirm the debugging permission.

adb shell settings put global fast_charge 0

To turn back on, use:

adb shell settings put global fast_charge 1

⚠️

Some Xiaomi models (e.g. Redmi) K50 or POCO X5 Pros can ignore this command due to hardware limitations, in which case try the alternative command: adb shell settings put global settings battery_charging_limit 1 It limits the charging current to standard values.

Once you have completed the commands, restart the device. To check the result, use the AccuBattery app (available on Google Play) to show the current charging power.

💡

ADB-If you're not sure what you're doing, you're going to have to use a standard setting or an engineering menu.

5.What to do if the fast charging does not turn off?

If none of the methods worked, the reasons may be as follows:

• 🔌 Unoriginal charger: Some power supplies force fast charging by ignoring smartphone settings.Try Xiaomi's original adapter.
• 🔋 Restricted firmware: on custom or "cut" versions MIUI (For example, for the European market, the option may be blocked.
• 🛠️ Hardware lock: on flagships with ultra-fast charging (for example, Xiaomi) 11T Pro 120W) Disconnection may require re-flashing.

Alternative solutions:

• 📉 Use a charge limit of up to 80% (available in Settings) → Battery → Charging settings. This will reduce battery load without completely shutting down fast charging.
• 🔄 Install custom software (such as LineageOS or Pixel Experience) where charging is more flexible.
• 🧰 Contact Xiaomi Service Center – they can disable the feature at the firmware level (paid).

If the problem is overheating, try charging your smartphone in airplane mode or with the screen off, which will reduce the load on the processor and reduce heat generation.

6. Consequences of turning off fast charging: pros and cons

Before you make a decision, evaluate the pros and cons. We've put together the key implications in a table:

💡 Tip: If you have turned off fast charging to extend battery life, combine this with other measures:

• 🔄 Avoid full discharge (charge at 20–80%).
• ☀️ Do not leave your smartphone in the sun or near heat sources.
• 🔌 Use only original or certified cables.

7. Frequent mistakes and how to avoid them

When you turn off fast charging, users often face typical problems, and here's how to prevent them:

❌ Error 1: The smartphone does not charge after turning off fast charging through the engineering menu.

Solution: Return settings to the original state or reset via Settings → System → Reset settings (without deleting data).

❌ Error 2: After use ADB-The fast charging commands are switched on by itself.

Solution: Check if the settings are reset after the reboot. If so, use the command:

adb shell settings put global fast_charge_persist 0

❌ Error 3: The device warms up even after turning off fast charging.

Solution: The problem may be background software or battery failure. Check the temperature through AccuBattery and contact the service if necessary.

⚠️

Attention! If the smartphone starts to discharge faster than usual after the fast charge is turned off, this may indicate a malfunction of the power controller, in which case a diagnosis is required at the service center.
