How to turn off fast charging on Xiaomi Redmi Note 8 Pro: 5 proven ways

Xiaomi Redmi Note 8 Pro features Quick Charge 3.0 fast charging technology that can restore battery power to 50% in just 30 minutes. However, accelerated charging has the downside: increased battery heat, accelerated wear of lithium polymer cells and potential risks to the durability of the device. If you notice that the smartphone overheats during charging or the battery has become worse, turning off fast charging may be a smart solution.

In this article, we’ll take a look at all the ways you can disable fast charging on the Redmi Note 8 Pro, from standard MIUI settings to hidden engineering menus and third-party utilities, and how to check if the feature is deactivated, and what alternative methods can help reduce battery load without completely abandoning Quick Charge.

Why do you need to turn off fast charging on the Redmi Note 8 Pro?

Quick Charge technology is convenient, but not always battery-friendly, and here are the key reasons Redmi Note 8 Pro users decide to deactivate it:

• 🔥 Overheating of the device - with fast charging, the battery temperature can exceed 40°C, which reduces its resource.
• 📉 Accelerated battery degradation – Lithium polymer cells lose capacity faster at high charging currents.
• ⚡ Unstable voltage – cheap chargers can deliver incorrect voltage, which is dangerous for the power circuit.
• 🛌 Night charging – leaving your smartphone on fast charging all night is bad for the battery.

Smartphone makers, including Xiaomi, often don’t advertise the ability to disable Quick Charge, as it’s a marketing advantage. However, in the Redmi Note 8 Pro (begonia model), this feature can be deactivated software or hardware — more on that.

Method 1: Disconnect via standard MIUI settings

The easiest method is to use the built-in MIUI options. Unfortunately, the Redmi Note 8 Pro does not have a direct checkmark "Disable Fast Charging", but you can limit the power indirectly:

1. Open Settings → Battery and Performance.
2. Go to the Battery Settings section → Charging mode.
3. Select the option Standard Charging (if available) or Optimized Charging.

If these are not available, try an alternative route:

1. Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
2. Return to the additional settings → Developer settings.
3. Find the option to limit charging current or USB-debugging (charging settings).

Check the MIUI version (should be at least 12)

Use the original cable and power supply

Charging must be connected to the smartphone

Make a backup copy of the data (just in case)-->

Important: Some Redmi Note 8 Pro firmware (especially global ones) may not have these options, so move on to the following ways.

Method 2: Engineering menu (#4636##)

The hidden engineering menu allows you to control charging options that are not available in the standard interface.

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. Select the Battery Information section.
4. Find the AC Charge or USB Charge bar – this shows the current charging power.

To turn off the fast charging:

1. Go to Battery Settings (if the section is available).
2. Find the Fast Charge or Quick Charge option and deactivate it.
3. Save the changes and restart the device.

Warning: Changes to the engineering menu can cause the device to run in an unstable way. Don't change the settings unless you're sure they're intended!

💡

Before entering the engineering menu, write down the current AC Charge and USB Charge settings, which will help you return the settings back if something goes wrong.

Method 3: Use ADB-Teams (for advanced users)

If standard methods fail, you can turn off fast charging via ADB (Android Debug Bridge), which requires a computer and basic command line knowledge.

Steps:

1. Install ADB and Fastboot Tools on PC.
2. Turn on USB debugging on your smartphone (Settings → About Phone → MIUI Version → 7 times Press → Developer Settings → Debugging by USB).
3. Connect the Redmi Note 8 Pro to your computer and confirm the debugging permission.
4. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell


su




echo 0 > /sys/class/power_supply/battery/fast_charge

If the command is error-free, fast charging is disabled. To get it back, replace 0 with 1.

💡

ADB-The teams only work on rooted devices or with an unlocked bootloader.

Warning: Incorrect use of ADB can lead to a device blink. If you are not sure about your actions, skip this method.

Method 4: Third-party applications for charging management

Google Play has apps that allow you to control the charging current. The best options for the Redmi Note 8 Pro are:

• 📱 AccuBattery – monitors battery health and limits charging current (root required for full functionality).
• ⚡ Battery Charge Limit – allows you to set a charge limit (for example, 80%) and reduce the charging speed.
• 🔧 Quick Charge Disabler is a specialized utility for disabling Quick Charge (does not work on all devices).

Example of settings in AccuBattery:

1. Install the application and provide all necessary permissions.
2. Go to the Charging section → Current restriction.
3. Set the maximum current at 1000-1500 mA (this will turn off fast charging).
4. Activate the option to limit the charge.

Without root rights, applications can only monitor charging, but not block Quick Charge at the system level.

Method 5: Hardware shutdown (using a non-original charger)

If the software methods didn't work, you could do a trick: use a charger that doesn't support Quick Charge.

• 🔌 Charging from an old smartphone (5V/1A or 5V/2A).
• 💻 Charging through USB-port.
• ⚡ Power Bank without fast charging support.

How it works: The Redmi Note 8 Pro automatically detects the power supply. If the charger only delivers 5V, the smartphone will go into standard charging mode.

Warning: Using low-quality chargers can damage the battery or power circuitry of your smartphone.

How to check if fast charging is turned off?

To make sure that Quick Charge is actually deactivated, follow the following steps:

1. Connect your smartphone to the charger.
2. Open the settings → Battery and look at the charging schedule.
3. If the speed does not exceed 1000-1500 mA, fast charging is turned off.
4. Install the Ampere app (from Google Play) – it shows the current charging current in real time.

Signs that Quick Charge is still active:

• 🌡️ The smartphone gets very hot during charging.
• ⚡ In the first 30 minutes, the charge is at a speed. > 2000 m.
• 🔋 In the status bar, the icon "Fast charging" is displayed".

Frequent mistakes and their solutions

When you turn off fast charging, users often face problems, and here are the most common ones and how to fix them:

If none of these things worked, maybe your Redmi Note 8 Pro firmware has hard-wired Quick Charge support, and then you have the hardware solution of using non-original chargers.
