Disabling fast charging on Xiaomi Redmi 10: 5 proven ways

Quick Charge feature in Xiaomi Redmi 10 allows you to restore battery power in minutes, but it is not always good for the device. Many users face overheating of the smartphone, accelerated wear of the battery or just want to extend the battery life by reducing the load on it. In this article, we will analyze all the available ways to turn off fast charging, from standard settings to hidden features of the engineering menu.

It’s important to understand that the manufacturer doesn’t always provide a direct option to deactivate fast charging in basic settings, which is due to the marketing strategy: the feature is positioned as a key advantage of the smartphone. However, workarounds exist – and we will examine them in detail, including nuances for different versions. MIUI (You will also learn how to check if charging is turned off, and what to do if the smartphone ignores the changes.

Before you start setting up, make sure your Redmi 10 is at least 30% charged, which minimizes the risk of crashes when you manipulate system settings. And remember, some methods require super-user rights (root), which automatically deprives you of warranty.

Why you should turn off fast charging on Xiaomi Redmi 10

Modern lithium-ion batteries installed in Redmi 10 are sensitive to high charging currents. Despite the manufacturer's stated protection, accelerated charging has hidden disadvantages:

• 🔥 Battery overheating: With fast charging, the battery temperature can exceed 40°C, which reduces its resource by 15-20% per year of intensive use.
• 📉 Accelerated degradation: Each high-current charging cycle reduces battery capacity by 0.1–0.3% (vs. 0.05% for standard charging).
• ⚡ Risk of bloating: with systematic overheating, the likelihood of mechanical damage to the battery increases.
• 🕒 Unstable operation: Some users note lags and spontaneous reboots during fast charging.

Research from Battery University shows that the optimal charging mode for battery life is current no higher than the current. 1And under stress. 5In the case of Redmi 10 Standard charging gives exactly such parameters, while fast charging can reach the maximum. 2And/9V (18W). The difference in wear is 2 The year of operation may be up to 30% capacity.

In addition, the disconnection of accelerated charging is relevant in the following cases:

• 🔌 Use of non-original chargers (risk of damage to the power controller).
• 🌡️ Operating a smartphone in hot climates or under direct sunlight.
• 💤 overnight charging (high current overcharging increases battery stress).

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use built-in options. MIUI. However, not all firmware versions provide direct access to this feature. MIUI 12.5–14:

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

If the Fast Charging option is not on the menu, try an alternative route:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version line to activate Developer Mode.
3. Go back to the basic settings, open Additional → for developers.
4. Find the charging configuration option and select Standard (5W).

Important: Some firmware may have hidden the option. If you don't find it, move on to the following ways. MIUI Settings may be reset – check them periodically.

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

The Engineering Mode provides access to hidden system settings, including charging settings, which works on most Xiaomi devices, but requires caution – incorrect changes can lead to failures.

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 section.
4. Find the parameter. AC Charge Limit or Fast Charge Config.
5. Set the value of 500 (corresponding to 0.5A) or Disabled.
6. Save the changes and restart the device.

If the Charging section is missing, try an alternative path:

1. In the engineering menu, select Hardware Testing.
2. Go to Battery. → Charging Settings.
3. Turn off the Fast Charging Enable option.

Critical nuance: Changes in the engineering menu are not always saved after rebooting. To fix the settings, after turning off fast charging, immediately connect the phone to the charger and wait for charging to start - this will "seal" new parameters in the power controller.

Method 3: Charging management applications (without root)

If the standard methods don't work, you can use third-party utilities, which don't require superuser rights, but they depend on the version. MIUI The best options for the Redmi 10:

The recommended algorithm for working with Battery Charge Limit:

1. Install an app from the Play Market.
2. Open it and give access to Special Features (in Android settings).
3. In the Charging Control section, set the maximum current to 1000 mA (1A).
4. Activate the Enable Charge Limit option.
5. Connect the charger – the application will automatically limit the current.

💡

If the app doesn’t limit current, try turning off battery optimization for it in Settings → Annexes → Special access → Optimizing the battery.

Note that these applications do not block fast charging at the hardware level, but only limit the current consumed.

• 📱 The charger will still work in Quick Charge mode, but the phone will take less current.
• ⚡ Charging speed will drop, but not to standard charging (usually up to 7–10W instead 18W).
• 🔄 The application may conflict with system services MIUI, languishing.

Method 4: Disconnect via ADB (for advanced users)

Android Debug Bridge Tool (ADB) It allows you to change system settings without root permission, and it's a method that's suitable for users who are willing to work with the command line:

• 🖥️ Computer with drivers installed ADB.
• 📱 Included Developer Mode and Debugging by USB phone-on.
• 🔌 Original. USB-cable (for stable connection).

Step-by-step:

1. Connect Redmi 10 to your PC and confirm debugging access on your phone screen.
2. Open the command prompt (cmd) on your computer and type:

adb shell


settings put global fast_charge_enabled 0

1. Reboot your phone with the command:

adb reboot

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

Verification of the result:

1. Connect the phone to the charger.
2. Enter the ADB:

adb shell dumpsys battery

1. Find the charge counter line – if the current value does not exceed 1000 mA, the setting is applied successfully.

💡

Changes through ADB They are saved after restarting, but can be reset after updating. MIUI. For reliability, fix the settings after each update.

⚠️ Attention: Wrong commands ADB Do not use this method unless you are sure of your actions. Also note that on some firmware Xiaomi blocks the change of the parameter. fast_charge_enabled — In this case, the team will return the error Permission denied.

Method 5: Physical shutdown (for extreme cases)

If software methods fail, the radical solution is to modify the charger or cable, which is only suitable for advanced users and is not warranty-free.

Option 1: Use of a “stupid” charger

Fast charging is only activated when using compatible chargers that support Quick Charge or Power Delivery protocols.

• 🔌 Get Redmi on board. 10 gateway 5V/1A (For example, from an old Nokia or Samsung smartphone sample 2015 year-end).
• 🔧 Use it. USB-cable without Quick Charge support (usually cheap cables without an identification chip).

Option 2: Modification of the cable

Inside. USB-The cable has the line data (D)+ And D-, which transmits information about fast charging support, and if you lock them or turn them off, the phone will charge as normal:

1. Take it apart. USB-cable connector (from the side of the phone).
2. Find the green (D)+) and white (D-) wires.
3. Snack them carefully or isolate them separately from the rest.
4. Collect the connector back and check the charging.

⚠️ Warning: Modification of the cable or charger may result in:

• Lose the phone warranty.
• Damage to the smartphone power controller.
• Fire when using low-quality components.

This method is recommended only in extreme cases when other methods do not work, and fast charging causes real harm to the device (for example, when the battery is bloated).

How to check if fast charging is actually off

It's not enough to just change the settings -- you need to make sure the phone is actually charging in standard mode. Here are 3 reliable ways to check:

Method 1: Using battery information

1. Connect the phone to the charger.
2. Open the Settings. → Battery.
3. Slip on the charging schedule - a window with detailed information will appear.
4. Check the Charging Current (Charging current) setting:

• ✅ ≤1000 mA - Standard charging.
• ❌ >1500mA – Fast charging is still active.

Method 2: Appendix Ampere

The Ampere utility shows the real charging current in real time:

1. Install an app from the Play Market.
2. Connect your phone to charge and open the Ampere.
3. Compare the readings with the table:

Method 3: Charging time test

Find out how long it takes to charge from 20% to 80%:

• ⏳ Standard charging: ~2.5-hours--3 hours.
• ⚡ Fast charging: ~1-1.5 hours.

If the phone is still charging too fast after the fast charge is turned off, then:

• 🔄 The settings are not saved (try repeating the procedure).
• 📱 Firmware ignores changes (root or custom required) ROM).
• ⚡ Forcing-mode charger (try another RMS).

Frequent mistakes and their solutions

When you turn off fast charging, users often face typical problems, and let's look at the most common and ways to fix them:

Error 1: Settings are reset after rebooting
