How to turn off fast charging on Xiaomi Mi 10: all ways

Xiaomi Mi 10 is the flagship smartphone with support for ultrafast charging Quick Charge 4+ and 30W, but not always high battery replenishment speeds are good for the device. Overheating, accelerated battery degradation and even the risk of damage to the power controller are just some of the problems that owners face when actively using turbocharging. In this article, we will discuss how to safely disable fast charging on the Mi 10 (including the Pro and Ultra versions), what methods exist and how they differ.

It's important to understand that the manufacturer doesn't provide a direct option to deactivate fast charging in standard settings, because of Xiaomi's marketing policy, where charging speed is positioned as a key advantage. However, there are workarounds, from hidden engineering menus to third-party applications. We've tested all methods on MIUI 12-14 firmware and are ready to share working solutions.

Before you start, consider: disabling turbocharging will not void the warranty, but improper actions on the engineering menu can lead to failures. If you are not sure of your skills, use only official methods (section 2).

Why you should turn off fast charging on Xiaomi Mi 10

Modern lithium polymer batteries degrade faster at high currents and temperatures. Studies show that 30W of continuous charging reduces battery life by 15-20% after 1-1.5 years of active use.

• 🔥 Overheating: with fast charging, the battery temperature can reach 45-50°C, which accelerates the chemical processes of electrolyte destruction.
• 📉 Capacity degradation: After 300-400 30W charging cycles, the battery loses up to 30% of capacity (versus 15% in standard charging).
• ⚡ Risk for the power controller: High currents increase the load on the chips, which can lead to their failure.
• 🛌 Night charging: leaving your smartphone on turbocharge all night is the worst practice, as after 100% the battery continues to recharge with microcycles.

In addition, fast charging is only relevant in emergency situations: in everyday use, the difference between 30 W and 10 W is only 20-30 minutes (from 0% to 100%), while the harm to the battery is incomparable.

⚠️ Note: If you use non-original chargers or cables, the risk of battery damage from fast charging increases by 3-5 times. Even certified accessories from third-party brands (such as Anker or Baseus) may not meet Xiaomi standards.

Method 1: Disconnect via MIUI settings (official method)

The easiest and safest way is to use the built-in MIUI options. Unfortunately, there is no direct button in the Xiaomi Mi 10 to deactivate fast charging, but you can limit power indirectly through the Optimized Charging mode.

Instructions:

1. Open Settings → Battery and Performance.
2. Select Battery Settings → Optimized Charging.
3. Activate the switch and set the charging limit to 80-90%.
4. Turn on the option “Disable fast charging when you reach the limit” (will appear after activation of optimization).

This method does not completely shut down turbocharging, but reduces its intensity after reaching a predetermined threshold, suitable for those who want to extend the battery life without radical changes.

Method 2: Engineering menu (for experienced users)

If you need to turn off fast charging completely, you'll have to use the engineering menu, which is a method that requires caution, because the wrong settings can cause the power controller to malfunction.

Step-by-step:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that opens, select Battery Information.
3. Scroll down and find Fast Charge Config (or Quick Charge Config).
4. Change the value from Enabled to Disabled.
5. Save the changes and restart the device.

After the reboot, the smartphone will charge at standard power (5-10 W). To return fast charging, repeat the steps and return the Enabled value.

⚠️ Attention: On some firmware MIUI 13+ Fast Charge Config may not be available, in which case, try the alternative code: ##2846579## → ProjectMenu → Background Setting → Battery Charge → Fast Charge Switch.

Method 3: Using Third-Party Applications

If the engineering menu is not available, you can use third-party utilities.

• 📱 AccuBattery (Play Market): allows you to track charging speed and limit current through notifications, does not turn off fast charging completely, but reduces its intensity.
• ⚡ Battery Charge Limit (requires root): gives full control over charging options, including disabling Quick Charge.
• 🔧 3C Toolbox (root): advanced utility for power management, supports Xiaomi Mi 10 at the core level.

Without root rights, application functionality is limited, such as AccuBattery can only notify you of a high charging speed, but not block it. To completely disable it, you will need to unlock the bootloader and install a custom core (for example, FrancoKernel), which cancels the warranty.

Example of settings in AccuBattery:

1. Install the application and provide all necessary permissions.
2. Go to the Charging section → Current Limits.
3. Set the maximum current at 1000-1500 mA (this corresponds to ~5-7.5 W).
4. Activate the "Warn if exceeded" option.

💡

If your smartphone starts to warm up more after you install AccuBattery, turn off background monitoring in the app settings. Some versions of MIUI conflict with battery tracking services.

Comparison of methods: what way to choose

Each of these methods has its pros and cons, and in the table below we compare them by key criteria:

For most users, the best solution is a combination of the first and third methods: activating optimized charging in MIUI + using AccuBattery for monitoring, which will reduce the load on the battery without risk to the system.

💡

If you need to temporarily turn off fast charging (for example, overnight), just use the optimization mode in MIUI. For permanent shutdown, it is better to use the engineering menu or root solutions.

Frequent Mistakes and How to Avoid Them

When trying to turn off fast charging, users often encounter problems, and here are the most common mistakes and ways to solve them:

• 🔄 "Settings are not saved": After changing the settings in the engineering menu, restart the smartphone. If the changes are reset, try a different service code (see spoiler in section 3).
• 🔌 "Charging is too slow": Check the cable and power supply. Unoriginal accessories can limit current even when turbocharging is turned off.
• 📱 "Smartphone does not detect charging": This can happen if the power controller is accidentally turned off in the engineering menu.
• 🔋 "Battery discharges faster": After fast charging is turned off, the first 2-3 cycles of the battery may show unstable behavior.

If after manipulation, the smartphone stopped charging at all, reset settings through Settings → System → Reset settings → Reset network settings. This will return the parameters of the power controller to factory values.

⚠️ Attention: On some firmware MIUI 14 After you turn off fast charging, the charging indication on the lock screen may disappear through the engineering menu. This is not a critical error, but if it annoys you, use alternative methods.

Additional Tips for Extending Battery Life

Turning off fast charging is just one step to keeping the battery healthy, and here are some more recommendations for the Xiaomi Mi 10:

• 🌡️ Avoid extreme temperatures: Do not leave your smartphone in the sun or near heat sources. Optimal range is 10-35°C.
• 🔄 Calibrate the battery: once every 2-3 months, discharge the smartphone to 0% and charge up to 100% without interruptions.
• 🛌 Don't keep charging all night: even with turbocharging turned off, microcycles can damage the battery. Use smart timer outlets.
• 📴 Turn it off. 5G/LTE weak signal: finding a network in poor coverage increases the load on the processor and, as a result, on the battery.

Also worth keeping an eye on charging cycles: The Xiaomi Mi 10 uses a 4,780 mAh battery that is designed to last 500-600 cycles on standard charging, which is reduced to 300-400 cycles when fast charging is used actively.
