How to turn off fast charging on Xiaomi: 5 proven ways

Fast charging has become the standard for modern Xiaomi smartphones, but it doesnโ€™t always benefit the device. Many users notice that when you use this feature, the battery wears out faster and the phone heats up more during charging. Especially the problem for owners of models with low-capacity batteries (for example, Xiaomi 12 Lite or POCO F4), where every percentage of capacity counts.

In this article, weโ€™ll look at all the ways you can turn off fast charging on Xiaomi, Redmi and POCO smartphones, from standard MIUI settings to hidden engineering menus. Youโ€™ll learn which models support software shutdown and where youโ€™ll need to use workarounds. Weโ€™ll also analyze whether avoiding fast charging really prolongs battery life, and what alternative methods will help keep the battery healthy without losing convenience.

Why you should turn off fast charging on Xiaomi

Quick Charge, Turbo Charge, HyperCharge technology works by increasing current and voltage, which allows you to charge your smartphone by 50-70% in 30 minutes.

  • ๐Ÿ”ฅ Battery overheating - at high currents, lithium-ion batteries are heated to 40-45ยฐC, which accelerates the degradation of the electrolyte.
  • ๐Ÿ“‰ Reduced charging cycles โ€“ according to research, the battery loses up to 20% post-container 300-400 fast-charging cycles (against 500-600 standard).
  • โšก Risk of voltage spikes โ€“ non-original chargers can deliver unstable voltage, which is dangerous for the power controller.
  • ๐Ÿ› ๏ธ Wear of the connector USB-C โ€” High power increases the load on the contacts, which leads to their oxidation or mechanical damage.

It is especially critical to use fast charging on devices older than 2 years, where the battery has already partially degraded. For example, on the Xiaomi Mi 11 or Redmi Note 10 Pro after 800 charging cycles, the capacity can fall to 70% of the nominal one, and fast charging will only exacerbate the problem, and the manufacturer rarely warns about such consequences, focusing only on speed.

โš ๏ธ Note: On models with HyperCharge support (e.g. Xiaomi) 11T Pro or Black Shark 5 Pro) disabling fast charging through standard settings is often blocked. In such cases, you will need to use an engineering menu or third-party utilities.

Method 1: Disconnect via MIUI settings (official method)

The easiest and safest way is to use the built-in MIUI options. However, it does not work on all devices. For example, on the Xiaomi 13 Pro or POCO F5, this feature is available, and on the budget Redmi 10A or Redmi Note 12, this feature may not be available.

Instructions:

  1. Open the Settings app.
  2. Go to the Battery and Performance section.
  3. Select the Charging option (on some firmware - Charging settings).
  4. Find the option of Fast Charging or Turbo Charging and move the slider to the off position.
  5. Confirm the action if the system requests permission.

On some devices (such as the Xiaomi 12S Ultra), instead of completely shutting down, the Optimized Charging mode is available, which automatically limits current after 80% of charge. This is a compromise option for those who do not want to give up speed completely, but are worried about the health of the battery.

Connect the original charger

Charge your phone to 30-50% for testing

Restart the device after changing the settings-->

If your menu doesn't have Quick Charging, it means the manufacturer has blocked it for your model, so move on to the following options.

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

The Engineering Mode allows you to access hidden system settings, including charging options, which works on most Xiaomi devices, but requires caution โ€“ improper changes can lead to failures.

Step-by-step:

  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 AC charge (network charging) and USB charge (USB charging).
  5. Change the values from fast to normal or reduce the maximum current (for example, from 2000 mA to 1000 mA).
  6. Save the changes and restart the device.

On some firmware (e.g. MIUI 14 for Xiaomi 13), the engineering menu may be blocked, in which case try the alternative code: ##6484## (battery testing menu) or ##64663## (hardware testing menu).

Xiaomi modelEngineering menu codeAccess to charging settings
Redmi Note 11 Pro+##4636##Yes (Battery section)
Xiaomi 12T##6484##Yes (Charging section)
POCO X4 Pro##4636##Partially (current only)
Xiaomi Mi 11 Lite##64663##No (diagnosis only)

โš ๏ธ Warning: Changing the settings in the engineering menu can lead to unstable charging or even damage to the power controller.If the phone stopped charging after the changes, reset the menu settings to factory or run Wipe Battery Stats in Recovery mode.

Yes, to optimize charging.

Yes, but for other purposes.

No, I'm afraid to break my phone.

I don't know what that is.-->

Method 3: Applications for charging control (AccuBattery, Battery Guru)

If standard methods don't work, you can use third-party applications that limit the charging current programmatically.

  • ๐Ÿ“Š AccuBattery โ€“ analyzes the state of the battery and allows you to set the current limit (for example, 1.5A instead 2.5A). It supports most of Xiaomiโ€™s models on MIUI 12 and newer.
  • โšก Battery Guru โ€” offers Slow Charging and Night Charging modes that automatically reduce current after 80%. POCO root-righted.
  • ๐Ÿ”ง Quick Charge Switcher is a specialized application to disable Quick Charge at the kernel level.

Example of settings in AccuBattery:

  1. Install the app from Google Play.
  2. Go to the Charging section.
  3. Activate the option Charge current limit.
  4. Set a maximum value, for example, 1500 mA (for comparison: standard fast charging on the Xiaomi 11 Lite NE is 3300 mA).
  5. Save the settings and connect the charger.

Important: Root-free apps donโ€™t work on all firmware; on some devices (such as the Xiaomi 12S with MIUI 14), they can only monitor, but not limit, current.

๐Ÿ’ก

If AccuBattery doesnโ€™t limit current, try turning on Battery Savings mode in your Android settings, which will indirectly reduce charging speeds by 10-15%.

Method 4: Disconnect via ADB (for advanced users)

If previous methods have failed, you can use Android Debug Bridge (ADB), a low-level system management tool that requires a computer and basic command line knowledge.

Instructions:

  1. Download and install ADB Tools on PC.
  2. On the phone, turn on Developer Mode (7 times click on the Build Number in Settings โ†’ About Phone).
  3. In Settings โ†’ Additional โ†’ For developers, activate debugging over USB.
  4. Connect your phone to your PC and type in the command line: adb shell settings put global fast_charge_enabled 0
  5. Reset the device.

To check the current fast charging status, use the command:

adb shell settings get global fast_charge_enabled

If the result is 0, the function is turned off, 1 is turned on.

On certain devices (e.g, POCO F3 GT) instead fast_charge_enabled parameter battery_charging_enabled. To find the correct key, enter:

adb shell settings list global | grep charge

โš ๏ธ Attention: Teams ADB can conflict with firmware, especially on devices with a locked bootloader (Xiaomi) 13T, Redmi K50). If the phone is not charging after the change, reset: adb shell settings delete global fast_charge_enabled

Method 5: Hardware shutdown (for extreme cases)

If software methods donโ€™t work, the radical way is to physically limit current, which is true for devices with a faulty charging controller (for example, after a drop or moisture hit), where rapid charging leads to overheating or spontaneous reboots.

Options for hardware limitation:

  • ๐Ÿ”Œ Use of โ€œstupid" USB-Hub โ€“ connect your phone to charge via USB-Hub without Quick Charge support, it'll bring the current down to standard. 500-1000 mA.
  • ๐Ÿ”‹ Replace the charger โ€“ use the power supply with the output 5V/1A (Modern Xiaomi will automatically limit the current if they do not find support for fast charging.
  • ๐Ÿ› ๏ธ Modification of the cable - in soldering USB-C The cable can remove the resistor responsible for identifying fast charging (for power users only!).

For example, the charger from Xiaomi Redmi 9A (5V/2A) It does not activate Quick Charge. 3.0 on POCO X3 Pro, which allows you to charge in a gentle mode. However, this method increases the charging time in the 2-3 once.

What happens if you use slow charging all the time?
With a constant charge of 500-1000 mA, the full cycle time will increase to 4-6 hours, but the battery life will last by 20-30%. The main disadvantage is the inconvenience if you need to quickly restore charge. The optimal balance is to use slow charging at night and fast charging during the day if necessary.

How to check if fast charging is actually off

To make sure that the changes have taken effect, use the following methods:

  1. Amperรฉ app shows the current charging current in real time. After the fast charging is turned off, the value should not be higher than 1000-1500 mA (instead of 2500-3500 mA).
  2. Charging time โ€“ when you turn off fast charging recovery from 0 to 100% will take 3-4 hours (versus 1-1.5 hours in standard mode).
  3. Body temperature - touch the back panel near the camera while charging. If it's barely warm (up to 30ยฐC), fast charging is off. If hot (40ยฐC or higher), the function is still active.
  4. Audible Alert โ€“ Some Xiaomi models emit a characteristic sound when you activate fast charging. If not, the mode is off.

On Xiaomi 13 Ultra and other flagships with Surge P1 power management chip, you can additionally check the status through the CIT application (part of MIUI Diagnostics).

  1. Install CIT from the Mi App Store.
  2. Go to the Battery Test section.
  3. Check out the Fast Charge Status line, which should be Disabled.

FAQ: Frequent questions about turning off fast charging

Can you turn off fast charging on all Xiaomi models?
No, on some devices (e.g. Xiaomi 12S Ultra, Black Shark 5), this feature is locked at the firmware level, in which case only hardware restriction or ADB use will help.
Will the phone charge if you turn off fast charging?
Standard charging (5V/1A or 5V/2A) works on all devices, just a full cycle time will increase by 2-3 times.
How to turn off fast charging on the POCO F4 GT?
This model needs to be used. ADB-Adb shell settings put global fast_charge_enabled 0 Quick Charge Switcher with root rights.
Is fast charging harmful to the battery?
Yes, but the damage depends on the quality of the battery and the controller, and research has shown that if you use fast charging all the time, the battery capacity drops 15-20% faster than a standard charge.
Can I turn on the fast charge back after the shutdown?
Yes, all changes are reversible. To do this, repeat the steps in reverse order (for example, in the settings). MIUI through ADB-Settings put global fast_charge_enabled 1).
