How to turn off fast charging on Xiaomi Redmi Note 8 Pro: safe methods

Xiaomi Redmi Note 8 Pro features Quick Charge 3.0 fast charging technology that allows you to restore 50% of battery capacity in 30-40 minutes. However, not all users want to use this mode: some are afraid of battery wear, someone needs to slow down the heating of the device, and some simply prefer standard charging. In this article, we will discuss all the working ways to turn off fast charging on the Redmi Note 8 Pro – from official settings to hidden MIUI features.

It's important to understand that the manufacturer doesn't always provide a direct option to deactivate fast charging, and this is related to the marketing strategy of fast charging as a key advantage of the smartphone. However, there are workarounds, and we've tested them. Below you'll find methods of varying complexity, from basic to technically demanding, and choose the right one based on your skills and goals.

Why do users want to turn off fast charging?

At first glance, accelerated charging seems like a positive, but it also has a downside that forces Redmi Note 8 Pro owners to look for ways to turn it off:

• 🔋 Battery wear and tear: Fast charging increases battery load, reducing battery life by 10 to 15 percent after 300 to 500 cycles. This is critical for users planning to use a smartphone longer than 2-3 years.
• 🔥 Overheating of the device. When you are charging intensively, the body temperature can rise to 40-45°C, which is uncomfortable when held in the hands and potentially harmful to internal components.
• ⚡ Incompatible with cheap charging: Unqualified power supplies may misinteract with Quick Charge technology, causing crashes or even damaging the battery.
• 📉 Unstable work, on some firmware MIUI fast charging leads to accidental reboots or freezes while connecting to the network.

And then there's the category of users who just don't need to charge fast, so if you leave your smartphone on charge all night, for example, the difference between 2 and 4 hours of capacity recovery becomes insignificant, and then it makes sense to switch to standard mode to reduce the load on the battery.

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use the built-in MIUI options. Unfortunately, the Redmi Note 8 Pro does not have direct fast charging settings in most firmware versions, but there is a workaround through the power saving mode.

Algorithm of action:

1. Open the settings → Battery and performance.
2. Go to the Energy Savings section.
3. Activate the option Super Energy Saving or Energy Saving (depending on the MIUI version).
4. Connect the charger. The system will automatically limit the charging current to standard values (~1A instead of 2-3A in Quick Charge mode).

This method doesn't shut down fast charging completely, it only temporarily slows it down. Once the power saving mode is turned off or the device is reset, the restrictions will be reset, but for periodic use (for example, overnight), it is ideal.

⚠️ Attention: In some firmware MIUI 12.5+ Super Energy Saving can block background processes, including notifications. If push messages are important to you, choose the usual Power Saving mode.

Method 2: Use of the Engineering Menu (for advanced)

If the standard settings are not good, you can use the Engineering Mode, a method that requires caution, as incorrect changes can cause the device to malfunction, but allows you to flexibly adjust charging options, including disabling Quick Charge.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information.
3. Scroll down to AC Charge, which shows current current and voltage values.
4. Click on the Fast Charge Config field (if available) and select Disable.
5. Save the changes and restart the device.

Important: Some versions of MIUI for the Redmi Note 8 Pro may not have the Fast Charge Config option, in which case try an alternative path:

Settings → About Phone → MIUI version (click 7 times to activate developer mode)


Return to Settings → Additional → Developer → USB- Debugging (enable)




Connect your phone to your PC and use the ADB- command:




adb shell settings put global fast_charge 0

⚠️ Note: Changes to the engineering menu are not saved after resetting settings or updating the firmware. In addition, incorrect settings can cause the battery to overheat or refuse to charge.

Method 3: Applications for Charging Control

If you don't want to go through the settings, you can use third-party utilities that allow you to limit the charging current programmatically, simulating the standard mode.

• 📱 AccuBattery (Play Market) In addition to monitoring the battery status, the application can limit the charging current to a predetermined threshold (for example, 1A instead of 2.4A.
• ⚡ Battery Charge Limit (requires root) Allows you to set a charging limit (e.g. 80%) and turn off fast charging completely.
• 🔧 Kernel Adiutor (for users with unlocked bootloader) gives access to the core of the system where you can adjust the power settings.

Example of settings in AccuBattery:

1. Install the application and provide all the permissions requested.
2. Go to the Charging section → Current restriction.
3. Set the maximum current value at 1000 mA (1A).
4. Activate the option and connect the charger.

Important: without root rights, applications can run unstable, especially on the latest versions of MIUI with enhanced protection against system changes. If after setting the restrictions, the smartphone stopped charging at all, reset the application settings or delete it.

💡

Before using third-party utilities, check user reviews of your model. Some apps conflict with Android 10+ firmware for the Redmi Note 8 Pro, causing freezes.

Comparison of methods: which way to choose?

To make it easier, we've put together a table of pros and cons for each method, and focus on your technical skills and goals.

For most users, the best solution is to combine energy saving mode (for overnight charging) and AccuBattery (for day use). If you're willing to take the risk, an engineering menu or ADB will give a more stable result. Root methods are left to enthusiasts, since they require unlocking the bootloader and deprive you of warranties.

💡

On the Redmi Note 8 Pro with MIUI 13+ firmware, the engineering menu is often blocked, in which case the only working ways are power saving mode or third-party utilities.

Frequent Mistakes and How to Avoid Them

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

• 🔌 The smartphone doesn't charge after the changes, because it's a bad setting in the engineering menu or a conflict of applications, so you can reset the settings to the factory or remove third-party utilities.
• 📱 Fast charging starts on itself after rebooting. MIUI — The system resets the constraints. ADB-commands.
• ⚡ The device warms up more after the Quick Charge is turned off. Paradoxically, sometimes the current restriction leads to increased heating due to suboptimal charging algorithms.
• 🔋 The battery runs out faster. If you've limited charging to 1A but you're using your smartphone, the battery may not be able to recover. Try to increase the current to 1.5A.

Another common mistake is using non-original chargers. Even if you turn off fast charging, a cheap power supply can deliver unstable voltage, which negates all efforts. Always check the charging for compatibility with the Redmi Note 8 Pro (optimum: 5V/2A or 9V/2A).

⚠️ Warning: If after manipulating the charging settings, the smartphone starts to turn off on its own when connecting to the network, this is a sign of a failure of the power controller. Immediately return the standard settings and contact the service center.
