How to turn off fast charging on Xiaomi 8 Pro: all the ways and consequences

Xiaomi 8 Pro

Quick Charge 3.0

In this article, we’ll look at all the available ways to deactivate the feature on the Xiaomi 8 Pro, from standard settings to hidden options in the engineering menu. Also, you’ll learn what alternatives exist for gentle charging and how to check if the feature is actually disabled. It’s important to consider that the procedure may differ depending on the firmware version (MIUI or custom build), so we’ll look at the nuances for each case.

Before you make any changes, make sure your Xiaomi 8 Pro is at least 30% charged, which will prevent the device from suddenly shutting down during settings manipulations, and use the original cable and power adapter – uncertified accessories can ignore the fast charging limitations.

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use built-in MIUI options. However, not all firmware versions provide direct access to this feature. If you don't have the right item on your menu, move on to the next one.

Instructions:

1. Open the Settings app on the main screen.
2. Go to Battery and Performance (in some versions – Battery).
3. Select Battery Settings or Additional.
4. Find the Quick Charge option (can be called Quick Charge or Turbo Charging).
5. Move the slider to the off position.

If Fast Charging is not on the menu, it means that your version of MIUI is hiding this option, in which case the engineering menu or third-party utilities (more on this below) will help.

Check the version of MIUI in Settings → About the phone

Charge your phone at least 30%

Connect the original cable and adapter

Method 2: Use the engineering menu (#4636##)

The Engineering Menu is a hidden partition of Android that allows you to manage hardware features, including charging options. On the Xiaomi 8 Pro, access to this menu may be limited in the latest versions of MIUI, but it is worth trying.

How to open the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##4636###.
3. In the window that appears, select Battery Information.
4. Scroll down to AC Charging or USB Charging.
5. Change the value of Fast Charge from Enabled to Disabled.

⚠️ Warning: Changes to the engineering menu can cause the device to work in an unstable way. Do not edit other settings unless you are sure of their purpose.

If #4636### doesn’t work, try an alternative method:

1. Install the MTK Engineering Mode app from Google Play (for MediaTek processors) or Qualcomm EngineerMode (for Snapdragon).
2. Open the application and go to the Hardware Testing → Charging section.
3. Turn off the Fast Charging option.

💡

If the engineering menu does not open, check if access is blocked through security policies. MIUI. In this case, only root access will help or ADB-team.

Method 3: Disconnect via ADB (for advanced users)

If standard methods don't work, you can use Android Debug Bridge (ADB), a tool for debugging Android devices, which requires connecting your phone to your computer and basic command line knowledge.

Step-by-step:

1. Download and install ADB Tools on PC.
2. Turn on the developer mode on the phone (go to Settings → About phone and 7 times click on the MIUI version).
3. Return to Settings → Additional → For developers and activate Debugging over USB.
4. Connect Xiaomi 8 Pro to your computer and confirm the debugging permission.
5. Open the command line (Windows) or the terminal (macOS/Linux) Enter: adb shell settings put global fast_charge_enabled 0
6. Reboot the phone.

To return a quick charge, execute the same command by replacing 0 by 1.

⚠️ Attention: Misuse of the right ADB Before executing commands, make sure that the device drivers are installed correctly and the cable supports data transfer (not only charging).

Method 4: Use of third-party applications (Root required)

If you have root rights, you can use specialized charging control utilities. One of the most popular apps is AccuBattery, which not only tracks battery status, but also allows you to limit charging current.

How to set up AccuBattery:

1. Download and install the app from Google Play.
2. Open AccuBattery and provide root access (if requested).
3. Go to the Charging section.
4. Activate the option to limit the charging current.
5. Set the maximum current value at 1000-1500 mA (standard charging without acceleration).

Alternative annexes:

• 🔧 Kernel Adiutor – allows you to fine-tune the kernel parameters, including charging (requires root).
• ⚡ Battery Charge Limit – Limits charge to 80–90% to extend battery life.
• 📊 GSam Battery Monitor – Analyzes energy consumption and offers optimizations.

How to check if fast charging is actually off

After applying one of the methods, it is important to make sure that the changes have taken effect.

1. Through the AccuBattery app (no root):

Install the utility and connect the phone to the charger.

The screen will display the current charging speed in mA. If the value does not exceed 1000-1500 mA, fast charging is deactivated.

2. Through the engineering menu:

- Open ##4636## → Information about the battery.

- Look at the AC Charging (mA) setting, which should be ~1000mA on standard charging, 1800-2500mA on fast charging.

3. Visually:

When fast charging, the lock screen usually displays the words "Fast Charging" or "Lightning icon" and after turning off these indicators should disappear.

Consequences of turning off fast charging: pros and cons

Before you make a decision, weigh the pros and cons: turning off accelerated charging affects not only the time of recharge, but also its durability.

Advantages:

• ✅ Extending battery life – reducing charging current reduces battery wear by 20-30%.
• ✅ Less heat – the phone warms less, which is especially important in hot weather or heavy use.
• ✅ Stability – some users note that after switching off fast charging, random reboots are less likely to occur.

Disadvantages:

• ❌ Increased charging time – a full cycle can take up to 3-4 hours instead of the standard 1.5.
• ❌ Discomfort in travel – if you’re used to fast-powering your phone, not fast-charging can be a problem.
• ❌ Risk of failure if you disconnect incorrectly – if you use unproven methods (for example, editing system files without root).

💡

Turning off fast charging is advisable if you charge your phone at night or use it in a gentle mode. For active users who care about speed, it is better to leave the function on, but monitor the temperature of the device.

Alternative ways to charge Xiaomi 8 Pro

If you don’t want to give up fast charging altogether, but are worried about the battery’s health, take advantage of these tips:

1. Limit the charge to 80-90%:

In MIUI settings (Battery section), you can enable Optimized Charging option, which automatically stops charging by 80% (not available in all versions).

Applications like AccuBattery or Battery Charge Limit (with root) allow you to set your own threshold.

2. Use "smart" outlets:

Connect the charger to a timer outlet (such as Xiaomi Mi Smart Socket) and set up a power outage 1-2 hours after charging starts.

Charge at room temperature:

- Avoid charging in the cold (below) +10°C) or in the heat (above) +30°C) Optimal range: 15-25°C.

4. Turn off the phone while charging:

If possible, turn off the device while charging, which reduces battery load and speeds up the process (even when fast charging is turned off).

5. Use wireless charging:

Xiaomi 8 Pro supports Qi charging up to 7.5 watts. Wireless chargers usually heat the battery less than wired fast charging.
