Xiaomi’s fast charging feature has become the standard for most models, from the Redmi Note 4 (2017) to the flagship Xiaomi 14 series. However, not everyone is happy with this technology: some notice overheating of the battery, others want to extend the battery life, and still others simply prefer “slow” charging for safety. In this article, we will analyze all possible ways to turn off fast charging – from standard MIUI settings to hidden engineering menus and hardware solutions.
It is important to understand that the manufacturer does not always provide a direct option to deactivate this feature. ADB-We'll describe each method in detail, specify compatibility with specific models, and warn you of possible risks. POCO F5, Redmi 12 or Xiaomi 13T — Here you will find the right solution for your device.
Before you make any changes, check the current charging status: plug in the original power supply and look at the lock screen. If you see the Fast Charging or Lightning icon, the function is active. On some firmware (e.g. MIUI 14 Global), this information may be hidden in the battery menu. Next, consider all available options for shutting down, from the simplest to the most radical.
1. Disable fast charging via standard MIUI settings
The safest and most recommended way is to use the built-in options of the system. Unfortunately, it does not work on all devices: Xiaomi gradually removes this feature from new versions of MIUI, leaving it only on budget models (Redmi 9A, POCO M3) or in regional firmware (for example, for India).
- Open the Settings app (cog icon).
- Go to Battery and Performance (on some devices, just Battery).
- Slip on Battery Settings or Additional (depending on the MIUI version).
- Look for the option "Fast Charging" or "Restricting Charging" if it's not available, it's not the right way for your model.
The screenshots below show the MIUI 12.5 interface for the Redmi Note 10 Pro, where the option is available. Please note that even if you turn off fast charging here, when you plug in a non-original charger, the system can automatically activate it again. To avoid this, only use certified accessories from Xiaomi.
On devices with a Qualcomm Snapdragon processor (for example, Xiaomi) 11T or POCO F4) Even when you turn off fast charging in the settings, an accelerated mode can be maintained when using powerful power supplies (33W This is due to the hardware implementation of the power controller. QC 4.0/5.0.
2.Using a hidden engineering menu (#4636##)
If there is no standard switch in MIUI, you can try to turn off fast charging via the engineering menu.This method works on most devices with MediaTek processors (Redmi 10, POCO M4 Pro) and some models on Snapdragon (for example, Xiaomi Mi A3).
- Open the Phone app and enter the combination: ##4636##.
- In the menu that appears, select Battery Information.
- Scroll down to Fast Charge (can be called Quick Charge or MTK Fast Charging).
- Slip it and select Disable in the window that appears.
Then restart the device. On some firmware (e.g. MIUI 13 for Redmi Note 11), this option is reset after you reboot — check it before each charge. If the menu doesn't open or there's no quick charge item, then your model doesn't support this method.
What to do if the engineering menu does not open?
Warning: Changes to the engineering menu can cause charging to be unstable or even damage to the power controller.For example, on the Redmi 9T, after disabling the MTK Pump Express, some users experienced the device no longer recognizing chargers above 10W.
3. Disconnection through ADB-Teams (for advanced users)
If standard methods don’t work, you can use Android Debug Bridge (ADB), which requires connecting your smartphone to your computer and basic command line knowledge, and is suitable for most MIUI 11-15 devices, including the Xiaomi 12 Pro, POCO X5 and Redmi K50.
Install Xiaomi drivers on PC (download from the official website)
Enable USB debugging in the developer settings (Settings → About Phone → MIUI Version (7 times) → Return to Additional → For Developers)
Download the ADB platform (official source)
Connect your phone to the original PC USB-cable
-->
When you’re done, run the following commands in the terminal (Windows or Terminal on macOS/Linux):
adb devices
adb shell
settings put global fast_charge 0
settings put global wireless_fast_charge 0The first command checks the connection of the device, the second and the third turn off fast charging over the wire and wireless respectively. Once done, restart the smartphone. To return everything back, use the same commands, replacing 0 with 1.
⚠️ Note: On devices with Snapdragon 8 Gen 1/2 (for example, Xiaomi 13 Ultra: These commands may not work due to Qualcomm’s controller hardware limitations PMIC. In this case, try an alternative method with the editing of the build.prop file (described below).
To check the current fast charging status, use the command:
adb shell settings get global fast_chargeIf the output is 0, the function is disabled. On some firmwares (for example, MIUI EU), an additional command may be required to block the parameter change:
adb shell settings put global fast_charge_forced 04. editing system files (requires root rights)
The most radical software method is manual editing of the build.prop file or kernel configuration parameters, which is only suitable for users with an unlocked bootloader and Magisk installed.
Instructions for devices on Qualcomm:
- Install a file manager with root support (such as Solid Explorer or FX File Explorer).
- Go to /system/build.prop and back up the file.
- Add a line to the end of the file: persist.sys.qc30=false
- Save the changes, set rights 644 (r-w r--- r----).
- Reset the device.
For devices running MediaTek (Redmi Note 12, POCO M5), you will need to disable the settings in /vendor/build.prop:
ro.vendor.mtk_fastchg_support=0
ro.vendor.mtk_pump_express_plus_support=0If the changes stop charging at all, return the original build.prop file from the backup. Also note that after the MIUI update, all the edits will be reset — they will have to be repeated again.
💡
Before editing system files, create a full backup via TWRP Recovery or OrangeFox, which will allow you to restore the device in case of an error.
5. Hardware methods: modification of the charger
If the software didn't help or you don't want to risk firmware, the other way to do that is to physically limit the charging power, which is true for devices where fast charging is implemented at the charger level (e.g., Xiaomi 11 Lite NE with 33W support).
- 🔌 Use a lower power charger, for example, instead of the original unit. 67W (For Xiaomi 12 Pro, connect 10W or 18W. The system will automatically switch to standard mode.
- 🔧 Modify USB-Some cables (e.g. Redmi with yellow connector) have an additional resistor that identifies fast charging, which can be carefully removed or closed D pins.+ D-.
- 🔋 Connect an external controller. There are special adapters (for example, USB-C Power Limiter, which limits the current to 1A or 2A, slow-charging.
The easiest and safest way is the first, but keep in mind that some models (POCO F3 GT, Black Shark 5) can issue a warning “Slow Charging” or even block the use of uncertified power supplies, in which case only software shutdown (described above) will help.
| Method | Compatibility | Difficulty | Risks. | Reversibility |
|---|---|---|---|---|
| Standard settings of MIUI | Redmi 9/10, POCO M3, Xiaomi Mi A2 | ⭐ (simple) | No. | Yes. |
| Engineering menu | MediaTek (Redmi Note 11, POCO X3) | ⭐⭐ (middle-of-the-road) | Post-reset reset | Yes. |
| ADB-team | MIUI 12-15 (except Snapdragon 8 Gen 2) | ⭐⭐⭐ (difficult) | Damage to system files | Yes. |
| Editing by build.prop | Root access devices | ⭐⭐⭐⭐ (difficult) | Bootloop, loss of warranty | Yeah (backup) |
| Hardware modification | All models. | ⭐⭐ (middle-of-the-road) | Damage to cable/power supply | Yes. |
💡
On devices with Snapdragon 888/8 Gen 1 (such as Xiaomi 11T Pro), fast charging can be locked at the hardware level, in which case the only way is to use a charger with power below 18W.
Consequences of turning off fast charging: pros and cons
Before you make a decision, weigh the pros and cons: Turning off fast charging affects not only the rate of battery replenishment, but also its durability, temperature, and even the performance of the device.
- ✅ Extending battery life. Rapid charging increases battery wear ~20 to 30 percent per year (Battery University test data) If you turn it off, you can extend battery life by 100 to 200 cycles.
- ✅ Reduced heat: With fast charging, the battery temperature can reach 40-45°C, which has a negative impact on its capacity. Standard mode keeps the heating in the range of 30-35.°C.
- ❌ Increased charging time: For example, Xiaomi 13 Pro with 120W It charges in 19 minutes and is in standard mode (10W) — 2.5 hours.
- ❌ Possible malfunctions. Some models (POCO X4 Pro) the disabling of the fast charge results in incorrect display of the percentage of charge or inadvertent reboots.
If you use your smartphone intensively and charge it 1-2 times a day, turning off fast charging may be justified. However, for users who connect the device to the socket 1 time every 2-3 days, the difference in battery wear will be minimal. The optimal trade-off is to use fast charging up to 80%, and then switch to standard mode.
Fun fact: In Xiaomi lab tests, it was proved that a 10W battery loses only 10% of its capacity after 500 cycles, whereas at 30W+, the loss is 20-25%. However, this is only true for lithium polymer batteries (Li-Po), which are installed in modern smartphones.
Frequent Mistakes and How to Avoid Them
When you try to turn off fast charging, users often face typical problems, and we've collected the most common ones and ways to solve them:
- 🔄 The settings are reset once you reboot. This is true for the engineering menu on MediaTek. Solution: Use it. ADB Or edit build.prop.
- ⚡ It doesn't charge at all. You may have disabled all charging protocols. Solution: plug in the original power supply and check the settings in the adb shell dumpsys battery.
- 📉 The percentage of charge is stuck at the same level. POCO F2 Pro after editing system files Solution: Reset battery settings via Settings → Annexes → Application management → Three points. → Resetting application settings.
- 🔥 Overheating when charging. If the battery temperature exceeds 40°C even after you turn off fast charging, check the battery serviceability through AccuBattery or AIDA64.
If neither method worked, your model may be using a proprietary fast-charging protocol (e.g. Xiaomi HyperCharge on Xiaomi 11 Pro), leaving you with only two options: use a non-original power-limited charger or accept the current mode.
⚠️ Note: On devices with Wireless Fast Charge (e.g. Xiaomi) 13 or Mi 11 Ultra) disabling fast charging over the wire does not affect the wireless mode. To deactivate it, you will need to separately execute the command settings put global. wireless_fast_charge 0 through ADB.
