How to turn off fast charging on Xiaomi phone: all ways + risks

Fast charging in Xiaomi smartphones is a handy feature that allows you to restore battery power in minutes. However, this advantage has a downside: accelerated battery wear, overheating of the device and reducing the overall battery life. If you notice that the phone has become faster to discharge or heat up a lot during charging, you may want to consider turning this feature off.

In this article, we’ll look at all the ways you can turn off fast charging on Xiaomi, Redmi and POCO devices, from standard settings to hidden engineering menus, and learn which models support this option, how to check your current charging mode and what to do if the feature doesn’t turn off, and focus on hidden risks that the manufacturer doesn’t mention and alternative methods for extending battery life.

Why do you need to turn off fast charging?

At first glance, fast charging seems like the perfect solution: plug in your phone for 20 minutes, and you can use it for a few more hours, but it has hidden drawbacks that come to light over time.

• 🔋 Battery degradation: Lithium-ion batteries wear out faster at high charging currents. 300-500 The cycles may decrease the capacity 20-30%.
• 🔥 Overheating of the device: Accelerated charging raises the battery temperature, which negatively affects the chipset and other components.
• ⚡ Unstable voltage: Cheap chargers or cables can cause voltage surges, which is dangerous for electronics.
• 📉 Reduced life: With constant use of fast charging, the battery may fail 1-2 year-on-year.

It is especially important to turn off fast charging in the following cases:

• 📱 You’ve been using Xiaomi for over 2 years and the battery has gone down fast.
• 🔌 You charge your device overnight or leave it connected to the network for a long time.
• 🌡️ The phone warms up strongly during charging (over 40)°C).
• 🔄 You plan to sell or transfer your phone to another user and want to keep the battery in good condition.

Manufacturers, including Xiaomi, rarely focus on these issues, as fast charging is one of the key marketing arguments, but independent tests (such as from DXOMark or GSMArena) confirm that when you turn off this feature, the battery lasts 15-25% longer.

Which Xiaomi models support fast charging?

Not all Xiaomi smartphones allow you to manually disable fast charging, which depends on the version of MIUI, hardware platform and even the firmware region.

If your model is not in the table, check it on the official Xiaomi website in the specifications section. Note that even if the feature is available, it may disappear after updating the firmware. For example, in MIUI 13 the option was open access, and in MIUI 14 it was moved to the engineering menu.

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use the built-in settings, which works on most flagship and mid-budget models with MIUI 12 and later.

1. Open the Settings app (cog icon).
2. Go to Battery and Performance (or simply Battery on older versions).
3. Slip on the Charging or Charging settings item.
4. Find the Quick Charging option (can be called Turbo Charging or Quick Charge).
5. Move the slider to the off position.

If you don’t have the option on this menu, try an alternative route:

1. Settings → Special features → Additional → Optimization of charging.
2. Turn on Adaptive Charging mode - this will limit the current to safe values.

Check the current version of MIUI in Settings → About the phone

Connect the original charger

Charge the battery to at least 30% (to avoid failures)

Make a backup copy of important data

-->

Some firmware (such as Chinese) may have a hidden item, in which case a change in the region of the system will help:

1. Go to Settings. → Additionally. → Region.
2. Choose India or Europe (where certification requirements are stricter).
3. Restart your phone and check for the option again.

⚠️ Note: On models that support wireless charging (such as the Xiaomi 13 Pro), disabling fast charging over the cable does not affect wireless mode.

Method 2: Engineering menu (for experienced users)

If the standard settings don’t work, you can use the engineering menu (#4636## or #3644633###) which works on 80% of Xiaomi devices, but you need to be careful – wrong actions can lead to a system failure.

Step-by-step:

1. Open the Phone app and type in the combination: ##4636## If it didn't work, try: ##3644633###
2. In the menu that opens, select Battery Information (or Battery Information).
3. Scroll down to Fast Charge Config or Charge Control.
4. Change the value from Enabled to Disabled.
5. Save the changes and restart the phone.

On some models (for example, Redmi Note 11 Pro+) the path may be different:

• In the engineering menu, select Hardware Testing.
• Next up is Battery → Charge Settings.
• Turn off the Fast Charge and Turbo Charge options.

⚠️ Note: On devices with Qualcomm Snapdragon processor (e.g, POCO F4 GT) Changing the parameters in the engineering menu can reset the communication module. IMEI!

Method 3: Disconnect via ADB (for advanced)

If previous methods didn’t work, the Android Debug Bridge (ADB) option remains.It’s a versatile tool for deep customization of Android, but it requires a computer connection and basic command line knowledge.

What you need:

• 🖥️ Computer with Windows/macOS/Linux.
• 🔌 USB-cable (preferably original).
• 📱 Included debugging by USB phone-on.
• 🛠️ Utility. ADB (download from the official website).

Instructions:

1. Activate Developer Mode: Go to Settings → About Phone. Tap 7 times on MIUI Version. Go back to Settings → Additional → Developer. Turn on USB Debugging.

Connect the phone to the PC and confirm the debugging permission.

Terminal

adb devices

Make sure the device is identified.

adb shell settings put global fast_charge 0

Reboot the phone.

To return fast charging, use the command:

adb shell settings put global fast_charge 1

adb shell settings put global miui_optimize_battery_charging 1

This will enable adaptive charging that automatically limits current.-->

Models with a MediaTek processor (such as the Redmi Note 10 Pro) may require a different approach:

adb shell am broadcast -a android.intent.action.BATTERY_CHANGED --es status 2 --ei level 100 --ei voltage 4000 --ei temperature 250

⚠️ Attention: Misuse of the right ADB This may result in a loss of warranty or locking the bootloader.Do not change other settings unless you are sure of their purpose!

Method 4: Third-party applications (alternative)

If you don't want to dig into settings or connect your phone to a PC, you can use specialized applications. They don't always work 100 percent, but sometimes they help you bypass the limitations of MIUI.

Top.-3 tested applications:

• 📌 AccuBattery — analyzes the status of the battery and allows you to limit the charging current. Download to Google Play.
• 📌 Battery Charge Limit – sets a charge limit (e.g. 80%), which indirectly reduces the speed.
• 📌 Quick Charge Switcher – switches charging modes (does not work for all Xiaomi).

Instructions for AccuBattery:

1. Install and open the application.
2. Go to the Charge tab.
3. Activate the option to limit the charging current.
4. Set the maximum value within 1000-1500 mA (standard charging usually goes to 500-1000 mA).

For Battery Charge Limit (root required):

1. Give the application superuser rights.
2. Set the charge limit to 80%.
3. Enable the Slow Charge Mode option.

💡

If the app asks for root rights but you don't want to root your phone, try temporarily activating them through Magisk (Root in RAM method).

Cons of this method:

• ❌ Applications may conflict with MIUI cause errors.
• ❌ Some features only work on rooted devices.
• ❌ After updating the firmware settings can be reset.

How to check that fast charging is actually turned off?

Turning off the function is half the battle, and you have to make sure that the phone is actually charging in standard mode.

• 📊 Through settings MIUI: Connect the charger. Open the settings. → Battery. Look at the charging schedule: if the current is less than 1000 mA, fast charging is off.

Ampere

• Install Ampere.
• Connect the charging and launch the application.
• If the value is less than 1.0-1.5A, it is fine.

By charging time.

• Discharge the phone to 10%.
• Connect the charger and record the time to 100%.
• If the charging took >2.5 hours, the fast mode is turned off.

Temperature.

• Check the temperature of the case (you can use the CPU Monitor).
• If it does not rise above 35°C, fast charging is not active.

On some models (such as Xiaomi 12S Ultra), when you turn off fast charging, the status bar will show the words Standard charging instead of Fast charging. If it is not, use Ampere for accurate diagnosis.

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

Sometimes, even after all the manipulations, the phone continues to charge in an accelerated mode.

If nothing helps, radical measures remain:

• 🔧 Firmware of custom Recovery (for example, TWRP) file editing /system/build.prop.
• 🔄 Reverse to an older version MIUI, where the option was available.
• 🛠️ Hardware shutdown (replacement of the charging controller in the service center).
