How to disable accelerated charging on Xiaomi smartphones: all ways

Accelerated charging in Xiaomi smartphones is a convenient feature that allows you to quickly restore battery power. However, not all users want to use it: some are afraid of battery wear, some do not like the heating of the device, and some simply prefer a slow but gentler charging. In this article, we will discuss all the available ways to turn off fast charging on Redmi devices, POCO and Mi-series – from standard settings to hidden features of the engineering menu.

It is important to understand that the process of disconnection can vary depending on the model of the smartphone and the version of the MIUI firmware. We will consider the universal methods that work on most devices, and also point out the features for specific lines. If you are not sure about your actions, do not rush to make changes to the system settings: some parameters can affect the stability of the phone.

Why do users want to turn off fast charging?

Despite the obvious benefits of accelerated charging, it also has drawbacks that make Xiaomi owners look for ways to deactivate it.

• 🔋 Battery wear: high charging speed increases battery load, reducing battery life 10-15% post 1-2 year-long.
• 🔥 Overheating of the device: with fast charging, the smartphone can heat up to 40-45°C, which is uncomfortable for the hand and potentially harmful to the internal components.
• ⚡ Instable power: In regions with frequent voltage surges, accelerated charging can cause failures or even damage to the power controller.
• 📱 Accessory Compatibility: Some powerbank or wireless charging devices do not support Xiaomi’s fast charging protocols, which means the device either does not charge or does so extremely slowly.

In addition, many users note that when you turn off fast charging, the smartphone keeps the charge in standby mode longer, this is due to the fact that the power controller does not waste energy to maintain high currents, but the effect is negligible – the difference is usually no more than 5-7% per day.

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use the built-in MIUI options. It is suitable for most modern models, including the Redmi Note 10/11/12, POCO X3/X4/X5, Mi 11/12 and other devices based on MIUI 12-14.

1. Open the Settings app (the gear icon on the home screen).
2. Go to Battery and Performance (some models may call it Battery).
3. Select Battery Settings or Additional Settings.
4. Find the option Fast Charging (sometimes hidden under Charging Modes).
5. Switch the slider to the off position. or select the Standard Charging mode.

On some devices (such as the POCO F3 or Redmi K40), instead of completely turning off, you can choose between fast, moderate and slow modes.

⚠️ Note: On smartphones with MIUI 13+ If you turn off fast charging, you may notice that you're in a "suboptimal mode" mode, and you can ignore it, because it doesn't affect the functionality of the phone.

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

If the standard settings do not have the option to turn off fast charging, you can use the engineering menu. This method requires caution, since improper actions can disrupt the device. Suitable for Xiaomi models based on Qualcomm Snapdragon processors (for example, Redmi Note 9 Pro, POCO X3 NFC).

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information.
3. Scroll down to the Charging (or USB) section.
4. Find the Fast Charge option (can be called Quick Charge or Turbo Charge).
5. Change the value from Enabled to Disabled.

Some firmwares instead of digital code, you need to use the EngineerMode app (available on Google Play).

1. Launch the application and go to Hardware Testing → Charger.
2. Turn off the Fast Charge and PD Charge options (if any).
3. Save the settings and restart the device.

⚠️ Note: On devices with MediaTek processors (e.g. Redmi) 9T, POCO M3) The engineering menu may not contain options to turn off fast charging.In this case, use Method 3 (ADB).

💡

Before entering the engineering menu, back up your data via Settings → Additional → Backup. This will help you restore your settings if something goes wrong.

Method 3: Disconnect via ADB (for advanced users)

If previous methods have failed, you can use Android Debug Bridge (ADB), which requires connecting your smartphone to your computer and basic command line knowledge, and is suitable for all Xiaomi models on Android 10+.

Step-by-step:

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

USB debugging

• Back to Settings → Additionally. → For developers.
• Turn on the debugging switch over USB.
• Connect your smartphone to your PC and confirm your trust in your computer.
• Download and install ADB Tools.
• Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with adb.exe.
• Enter the command to check the connection: Adb devices should appear the name of your device.
• Execute the command to disable fast charging: adb shell settings put global fast_charge_enabled 0
• Reboot your smartphone.

The app will automatically limit charging speeds when you connect to the network. Please note that the feature will require permission to access Special Features (in Android settings).

Other useful utilities:

• 📊 Battery Charge Limit – allows you to set a charge limit (for example, 80%) and limit current.
• ⚡ Fast Charge Switcher – switches charging modes (requires root rights).
• 🔧 3C Toolbox – Advanced Battery Manager with Charging Profile Support.

⚠️ Note: Charging restriction applications may conflict with system processes MIUI. If after installation, the smartphone began to slow down or discharge quickly - delete the program and restart the device.

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

Sometimes, even after you've completed all the instructions, the smartphone continues to charge at an accelerated rate, and here are the possible reasons and solutions:

If none of the methods worked, your Xiaomi model may have hardware limitations, such as some flagships (such as the Xiaomi 12 Pro) only partially shut down fast charging – the device still uses increased current, but without activating the Quick Charge 4+ protocol.

💡

On wireless charging devices (such as the Mi 11 Ultra), disabling fast charging via cable does not affect the Qi charging speed.

Myths and Truths About Disabling Fast Charging

There are many myths surrounding the topic of fast charging, and we'll look at the most common ones.

• ❌ Myth 1: "Disabling fast charging will double the battery life". ✅ The real increase in battery life is no more 15-20% The main wear and tear is due to discharge cycles, not charging speed.
• ❌ Myth 2: "Slow charging completely eliminates heating". ✅ Truth: Even with standard charging, the smartphone can heat up to 30-35°C, especially if resource-intensive applications are used simultaneously.
• ❌ Myth 3: “Fast charging spoils the power controller". ✅ Truth: Modern Xiaomi smartphones have overload protection. The risk of damage to the controller is minimal if you use the original chargers.
• ❌ Myth 4: "Disabling fast charging will save electricity". ✅ The difference in electricity consumption between fast and slow charging is negligible (about the same time). 5-10%).
