How to turn off fast charging on Xiaomi smartphones: all ways

Fast charging has become the standard for modern Xiaomi smartphones, but it doesn’t always benefit the device. Many users note that aggressive charging mode leads to battery overheating, accelerated battery wear, or even unstable phone performance while connecting to the network. If you’re facing similar problems or just want to extend the life of your Redmi, POCO or Mi, this article will help you figure out how to properly turn off fast charging — temporarily or permanently.

It’s important to understand that the manufacturer doesn’t always provide a direct option to deactivate this feature in standard settings. So we’ll look at both official methods (where they are available) and alternative solutions, from engineering menus to third-party utilities. But before we make any changes, it’s worth weighing the pros and cons: sometimes turning off fast charging can lead to unexpected consequences, especially on models with proprietary protocols like Quick Charge 4+ or HyperCharge.

Why you might need to turn off fast charging

At first glance, being able to charge your smartphone in 30-40 minutes seems like the perfect solution, but there is a downside to this mode:

• 🔥 Battery overheating - at high currents, the battery heats up to 40-45°C, which reduces its resources to 15-20% After a year of active use.
• ⚡ Unstable power supply – Cheap chargers or damaged cables can cause power surges, which is dangerous for the power controller.
• 📉 Capacity degradation – Lithium polymer batteries lose to 3-5% capacity per year with intensive fast charging, against 1-2% standard-set.
• 🛠️ Accessory Compatibility – Some powerbank or wireless charging devices do not support Xiaomi protocols, which either prevents the phone from charging or makes it jerky.

Also, on forums, users often complain that fast charging interferes with the phone’s use while connecting to the network — the device starts to “slow down”, the games fly out, and the camera refuses to focus — this is because the power controller limits the performance of the processor to reduce battery load. If you notice these symptoms, it’s worth trying to switch to standard mode.

Official method: settings MIUI

On some Xiaomi models (mainly the flagships of the Mi 11/12 series and the Redmi K50), the manufacturer added the ability to limit charging power directly in the MIUI interface.

1. Open Settings → Battery and Performance.
2. Go to Charge section (on some firmware it may be called Battery Care).
3. Find the option of Limit Charging or Slow Charging Mode.
4. Activate the switch and select the power limit (usually 5W, 10W or 18W instead of the standard 33W/67W/120W).

If there is no such item on the menu, then your model does not support this feature at the software level, in which case you will have to use alternative methods. It is also worth considering that after the MIUI update, the location of the settings may change - for example, in versions 14+, the option is moved to Settings → Additional → Special Features → Battery Optimization.

Engineering menu: hidden charging settings

For advanced users willing to take risks, there is a way to turn off fast charging via the engineering menu (#4636##) which works on most Xiaomi devices, but requires caution – incorrect changes can lead to system 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 Configuration or Fast Charge Config section.
4. Find the Fast Charge, Quick Charge, or PD Charge settings and set the Disable value.
5. Save the changes and restart the device.

Note that item names may vary depending on the model and firmware version. On some devices (such as the POCO F3 or Redmi Note 10 Pro), the engineering menu is blocked, in which case you will need to unlock the bootloader or root rights.

Use of the ADB-commands to disable fast charging

If standard methods don’t work, you can use Android Debug Bridge (ADB), a debugging tool that allows you to change system settings without root permissions, which is suitable for most Xiaomi models, including the Redmi Note 11, POCO X4 Pro and Mi 11 Lite.

Step-by-step:

1. Turn on Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect your phone to your PC, install Xiaomi drivers, and download ADB Tools.
4. Open the command line in the ADB folder and type in: Adb devices (your device should appear).
5. Execute the command to disable fast charging: adb shell settings put global battery_charging_limit 1 To return to standard mode, use: adb shell settings put global battery_charging_limit 0

This method temporarily limits the charging power to 5W, but after the device is restarted, the settings may reset. To fix the changes, you will need to create a script to automatically execute the command when you turn on the phone (for example, through the Tasker application).

💡

If ADB doesn’t recognize the device, try reinstalling drivers manually through Windows Device Manager. To do this, download the latest MiFlash package from Xiaomi’s official website and select the driver manually.

Third-party applications for charging management

If you don't want to mess with ADB or the engineering menu, you can use Google Play's customized utilities, which offer flexible current control settings, but require root rights or at least an unlocked bootloader.

• 📱 AccuBattery – analyzes the battery status and allows you to set a charging limit (for example, up to 80%), which indirectly reduces the load.
• ⚡ Battery Charge Limit – directly limits the charging current (requires root) and supports profiles for different chargers.
• 🔧 Kernel Adiutor is an advanced tool for fine-tuning the kernel, including charging options (for power users only).
• 🛡️ Greenify – although the main function of this application is to optimize the background, it can block the processes associated with fast charging.

When using third-party applications, be careful: some of them may conflict with Xiaomi system services, especially if the device has custom firmware installed. Before installing, check user reviews of your model - for example, on the POCO X3 Pro, the Battery Charge Limit application sometimes causes accidental reboots.

💡

Third-party charging management apps can void Xiaomi's warranty if using them causes battery damage.It's recommended to back up before experimenting.

Hardware methods: chargers and cables

If the software doesn't work for you, you can go the other way, which is to limit the power on the charger side. Here are some workable solutions:

• 🔌 Use “slow” RAM – connect your phone to charge on 5W (Most Xiaomi smartphones will automatically reduce the current to a safe level.
• 🔗 Power-limited cables – some USB-cables (e.g., 56 kOhm resistor) physically block fast charging protocols, which can be found on AliExpress for "slow charge cable».
• 🔋 Fixed current powerbank – many external batteries (e.g. Xiaomi Mi Power Bank) 3) have a switching button between modes 5W/10W/18W.
• 🔄 USB-hubless PD — If you connect the phone through USB-hub or extension without Quick Charge support, charging speed will drop to standard.

These methods do not require software intervention and are completely safe, but they have a disadvantage: you lose the ability to charge quickly even when you really need it, but this approach is ideal for overnight charging - the battery will charge slowly and without overheating.

⚠️ Warning: Don't use cheap, uncertified chargers to limit power. They may not only fail, but also damage your smartphone's power controller. When buying cables or adapters, check for certificates. USB-IF or MFi.

What to do if nothing helps: radical measures

If all of these methods have not worked, and fast charging causes serious inconvenience, there are two radical options:

1. Custom recovery and kernel firmware – some custom firmware (like LineageOS or Pixel Experience) allows you to flexibly adjust charging options, but this requires unlocking the bootloader and may be unwarranted.
2. Replacement of the power controller – in service centers, you can replace the charging control chip with a similar with limited power. It is expensive (from 3000 rubles) and risky, but gives 100% result.

Before you take such measures, evaluate how critical the problem is for you. It may be enough just to turn off fast charging overnight or use the original Xiaomi charger instead of cheap counterparts. It is also worth checking whether the damaged battery is causing overheating or slow charging - in which case replacing it will solve the problem without additional manipulation.

⚠️ Note: On Xiaomi models with HyperCharge technology (120W+) If you're software-based, you can turn off fast charging, you can make a power controller error, and then you can only charge when the screen is off, or you can't take the current at all. Before you experiment, check your model's compatibility on the forums. 4PDA or XDA Developers.
