How to Remove Fast Charging on Xiaomi: A Complete Guide with Hidden Features

Fast charging in Xiaomi smartphones is both a boon and a potential threat to the battery. On the one hand, the ability to charge the phone in 30-40 minutes saves time, on the other hand, accelerated charging cycles reduce battery life by 15-20% after 1-2 years of active use. If you notice that the smartphone warms up while charging, the battery discharges faster than usual or plan to store the device for a long time without using – turning off fast charging can be a smart solution.

In this article, we will look at all the available ways to deactivate the function, from standard MIUI settings to hidden engineering menus and hardware solutions. Particular attention will be paid to the Redmi Note 10/11/12 models, POCO F3/F4/F5 and Xiaomi 12/13/14 flagships, where charging algorithms differ, and you will learn how to check the actual charging speed after the function is turned off and what alternative methods will help to extend the life of the battery without completely abandoning the “fast” technology.

Why you should turn off fast charging on Xiaomi

Smartphone makers rarely advertise the negatives of fast charging, but independent tests (including research from Battery University and AnandTech) confirm that high currents and voltage accelerate the degradation of lithium-ion batteries.

• 🔥 Battery overheating: With fast charging, the battery temperature can reach 40-45°C, which reduces its resources to 30-50% regular-use.
• 📉 Reduced capacity: after 300-400 Fast charging cycles battery capacity drops to 70-75% from the original (against) 85-90% standard-charging).
• ⚡ Unstable voltage: Cheap chargers (especially non-original ones) can deliver unstable current, resulting in micro-damage to battery cells.
• 🛌 Long-term storage: If the smartphone lies unused for more than a month, fast charging can cause deep discharge or overcharging when connected to the network.

It’s important to understand that turning off fast charging won’t bring back the battery’s lost capacity, but it will slow further degradation by 40-60%, especially for smartphone owners over 1.5-2 years old, where battery wear is already noticeable in battery life.

⚠️ Note: On Xiaomi models with HyperCharge support (120W+) Disabling fast charging through standard settings may not work, in which case you will need to use an engineering menu or third-party utilities.

Method 1: Disconnect via standard MIUI settings

The easiest method is to use the built-in system options, which is suitable for most Xiaomi, Redmi and other models. POCO base MIUI 12-14. The instructions are relevant for devices with Qualcomm Snapdragon and MediaTek chips Helio/Dimensity:

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Battery and Performance section (on some firmwares - Battery).
3. Select Charging Settings or Charging Modes.
4. Deactivate the Fast Charge switch (could be called Turbo Charge or Quick Charge).
5. Confirm the action if the system requests permission.

On some models (e.g. Xiaomi 11T Pro or Redmi K50 Gaming), the option is hidden deeper, in which case the path will be: Settings → Special features → Additional → Charging Optimization. If there is no point, then your model does not support software shutdown (go to method 2 or 3).

Charge the phone before 50-70%|Use the original cable and adapter|Check the battery temperature (should be) <35°C)|Make a backup of the data (in case of resetting settings)-->

After the function is disabled, it is recommended to restart the smartphone. To check if the disconnection has worked, connect the charger and pay attention to:

• 📊 Charging indicator: if you previously displayed the words "Fast Charging" or "Turbo", and now it is not - the function is disabled.
• ⏱️ Charging time: the full cycle should take 2-2.5 hourly 40-60 quick-charging).
• 🌡️ Temperature: The phone should not heat up higher 30-32°C.

⚠️ Attention: On firmware MIUI Global and MIUI Europe may not have the option to disable fast charging due to regional limitations, in which case switching to a fast charging system will help. MIUI China or using custom firmware (e.g. Xiaomi.eu).

Method 2: Engineering menu (#4636##)

If standard settings fail, you can use a hidden engineering menu, which works on 80% of Xiaomi models, but requires caution – wrong actions can lead to malfunctions of the smartphone.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information.
3. Scroll down to Charging and find the Fast charge or Quick charge option.
4. Click on the setting and select Disable.
5. Save the changes and restart the device.

On some firmware, the engineering menu may look different. For example, on POCO F3, the path will be: Testing → Battery → Fast Charge Config. If the menu doesn't open, then your model is blocking access to these settings (try Method 3).

Method 3: Use ADB-Teams (for advanced users)

If the first two methods didn’t work, you can use Android Debug Bridge (ADB), a tool for debugging Android devices, which requires connecting a smartphone to a computer and basic command line knowledge, but produces 100% results on most models.

Step-by-step:

1. Download and install ADB Tools on PC.
2. Turn on Developer Mode on your smartphone: 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 the phone to the PC and enter in the command line (terminal):

adb devices

(Your device should be displayed)

adb shell


settings put global fast_charge 0

After you execute the commands, restart your smartphone. To return a quick charge, use the same command, replacing 0 with 1.

settings put global charging_scenario 0

This command resets charging scenarios, which sometimes helps on models with HyperCharge (120W+).-->

To check the current fast charging status through ADB, use:

adb shell settings get global fast_charge

If the command returns 0, the function is disabled, 1 is turned on.

Method 4: Disconnection through third-party applications

If you don't want to mess with engineering menus or ADBs, you can use third-party utilities.

• 📱 AccuBattery (free, Google Play): allows you to limit the charging current to 500-1000 It's a mA, which actually turns off the fast mode.
• ⚡ Battery Charge Limit (requires root): Set a charging limit (e.g., a battery charge limit, 80%) And it disables accelerated protocols. It supports Xiaomi on Snapdragon. 8 Gen 1/2.
• 🔧 QuickShortcutMaker (free): Helps you find hidden charging settings in MIUI, if they are hidden by the manufacturer.

Example of settings in AccuBattery:

1. Install and open the application.
2. Go to the Charging section.
3. Activate the option Charge Rate Limit.
4. Set the maximum current at 1000 mA (1A).
5. Save the settings and connect the charger.

⚠️ Note: Apps like AccuBattery don’t block fast charging at the hardware level, but only limit the current consumed, which can cause the charging adapter to overheat if it doesn’t support smooth power adjustment. Use only original or certified chargers.

💡

The app side is a temporary solution. After you reboot your smartphone or update your MIUI, your settings may reset. Use ADB or the engineering menu to permanently turn off fast charging.

Method 5: Hardware shutdown (for power users)

If the software methods don’t work (for example, on the Xiaomi 12S Ultra or Redmi K60 Pro with 200W HyperCharge), there is a hardware solution left, which involves physically disabling the contacts responsible for fast charging, or using special adapters.

Options:

• 🔌 Use of "stupid" cable: some USB-cables (e.g. cables, USB 2.0 without Quick Charge support) automatically limit current to 500 mA. Cables from older devices or special "slow" cords (sold on AliExpress as Slow Charge Cable) will fit).
• 🔧 Modification of the charging adapter: if you are versed in electronics, you can solder resistors in the charger so that it only gives out 5V/1A. Dangerous, short circuit risk.
• 📱 Replacement of the power controller: on some models (e.g, POCO F1) You can replace the charging control chip with a similar one without fast protocols.

The safest hardware method is to use a magnetic adapter (such as MagSafe-compatible) with a current restriction, which is often sold for laptops and can produce fixed 5V/2A, which is enough for standard Xiaomi charging.

What to do if nothing helps

If none of these methods worked, your Xiaomi model may be using a proprietary charging protocol (like the Surge P1 on the Xiaomi 12S) that is not software-enabled to shut down.

• 🔄 Update/roll back firmware: sometimes fast charging is turned off after switching to an older or, conversely, a new version MIUI. Check the forums 4PDA or XDA Developers for bugs in your firmware.
• 📲 Custom core installation: Cores like FrancoKernel or KirinKernel allow you to flexibly configure charging options, but require an unlocked bootloader and root rights.
• 🔋 Replacing the battery with a modified one: some Chinese manufacturers (for example, Huaqiang) produce batteries for Xiaomi with hardware-limited charging current.
• 📧 Appeal in support of Xiaomi: in rare cases, the manufacturer can provide special firmware without fast charging (relevant for corporate customers).

If you decide to leave fast charging, but want to minimize the damage to the battery, follow these recommendations:

• 🛑 Don't charge your phone before 100% — level-of-play 80-85%.
• ❄️ Avoid charging at temperatures below 10°C and above 30°C.
• 🔌 Use only original or certified chargers (Xiaomi, Baseus, Anker).
• 📵 Do not play games or run heavy apps while charging.
