Many owners of modern smartphones Xiaomi, Redmi and Poco face a dilemma: performance versus battery life. On the one hand, fast charging technology allows you to replenish energy in 30-40 minutes, which is incredibly convenient in the rhythm of modern life. On the other hand, the high currents and heating that accompany this process accelerate the chemical degradation of lithium-polymer cells, reducing the overall life of the battery.
If you plan to leave your device overnight at the power outlet, or if you use it in environments where the rate of recharge is not critical, forcing a limit on charging current power is a smart move, which will help reduce heat generation and minimize stress for the chemicals inside the battery. In this article, we will look at all the available ways to turn off fast charging on Xiaomi, from simple settings to advanced methods.
It is worth noting that in the standard interface MIUI or HyperOS, it is rare to find a simple button “Stop fast charging”. The system is focused on maximum efficiency and speed, so the user often has to resort to workarounds. Understanding the principles of the power controller will help you choose the best method for your model.
Why you should limit the charging power on Xiaomi
The main reason users are looking for a way to turn off fast charging on Xiaomi is to combat overheating. Using Quick Charge or HyperCharge protocols, the body temperature can reach 40-45 degrees Celsius or higher. Prolonged exposure to high temperatures negatively affects the battery electrolyte, leading to bloating or loss of capacity.
Also, limiting current is useful for overnight charging, so when the phone is under the pillow or on a soft blanket, the heat output is impaired, and in these conditions, the standard 5-10 watt speed is a much safer alternative to turbo modes, and you sacrifice time, but you gain in the life of recharge cycles.
⚠️ Attention: Constant charging at maximum currents (e.g, 120 Wh-wh 67 W) may reduce the battery life by 20-30% faster than the gentle regime.
Also worth mentioning is the impact on the power controller: Cheap or unoriginal cables may not be able to withstand the declared currents, which leads to voltage surges. By reducing the load, you reduce the risk of damage to ports and internal circuits of the device.
💡
Use thick cables labeled 5A or 6A only if you really need top speed. Normal 2A cables will do the job for overnight charging.
Use of the original charger and cable
The easiest and safest way to turn off fast charging without using third-party software is to manipulate the hardware. Fast charging protocols, such as Power Delivery or proprietary Charge Turbo, are activated only when there is a special dialogue between the charger and the smartphone.
If you replace the original power supply with a conventional 1 Ampere or 2 Ampere (5 Volt) output adapter, the phone will automatically go into slow charging mode, in which case the Turbo Charge or Quick Charge animation will not appear on the screen, but the standard battery icon will be displayed. This is guaranteed to limit power to 5-10 watts.
A similar effect is achieved by using a low-quality cable or cable that does not support high currents (for example, an old Micro-USB cable or a cheap USB-C).
- 🔌 Use an old power supply from another device (5V/1A or 5V/2A).
- 🔌 Replace the cable with a thinner or longer one (over 1.5 meters) that will increase the resistance.
- 🔌 Connect the phone to USB-port of a computer or television where the current is limited by a standard USB (0.5A - 0.9A).
💡
Replacing the charger with a less powerful one is the only 100% hardware way to guarantee that you can turn off fast charging without root rights.
Settings through the Engineering Menu (CIT)
A more advanced method available for some Xiaomi models is to use a hidden engineering menu, which is designed to test components and sometimes allows you to control charging parameters, although the functionality is heavily dependent on the version of the MIUI and the device’s processor.
To enter the menu, you need to open the Phone app and type a special code. The most common combination is ##6484## or #4636##. Once in the test menu, you need to look for the Battery Info or charging section, which may have a mode switching option, but in modern firmware it is often blocked.
##6484##
##4636##If you are lucky enough to find a suitable item, you can force the current limit. However, be careful: changing unknown parameters in the engineering menu can lead to unstable operation of the system.
⚠️ Warning: The engineering menu is a diagnostic tool. Don't change the values you're not sure about, as this can disrupt the calibration of the sensors.
Shutdown through ADB-team-mates
The most flexible software method, like turning off fast charging on Xiaomi, requires the use of a computer and a tool. ADB (Android Debug Bridge, which allows you to send commands directly to Android without the user interface constraints, USB-cable and on-line debugging USB smartphone.
First, activate the developer mode. Go to Settings → About Phone and quickly click on the build number (MIUI Version) seven times. Then, in the Advanced Settings menu, turn on “Debugging on USB.” Connect the phone to your computer and launch the ADB console.
There are a number of commands that can help limit charging, although their performance depends on the drivers of a particular power controller, such as commands to reset battery settings or set a charge limit (if supported by the core):
adb shell dumpsys battery unplug
adb shell dumpsys battery resetSome enthusiasts use scripts that monitor the temperature and send a command to stop charging when they reach a threshold, allowing the battery to run 1-2%, after which the cycle repeats, which creates a “drip” charging effect, which is very useful for maintaining the health of the battery during long-term connection to the network.
- 💻 Install the drivers. ADB and Fastboot on the computer.
- 💻 Put the debugging on. USB developer-menu.
- 💻 Use commands to control the battery condition (requires rights or specific conditions).

Comparison of charging limitation methods
The choice of method depends on your technical skills and goals. If you just need to charge your phone at night, just change the power supply. If you want to automate the process or do in-depth analysis, software methods will do. Below is a table comparing the effectiveness of different approaches.
| Method | Difficulty | Efficiency | Security |
|---|---|---|---|
| Weak power supply (5V/1A) | Low. | High (100%) | Absolute. |
| USB-port | Low. | Tall. | Absolute. |
| Engineering menu | Medium | Medium (depending on model) | Tall. |
| ADB team | Tall. | Medium/High | Medium (requires knowledge) |
As you can see from the table, using a weak power source is the safest and safest way to avoid interference with the code, and software methods provide more control, but require preparation and carry minimal risks when errors occur.
The hardware restriction works regardless of the Android or HyperOS version.
Alternative solutions: Smart sockets and timers
If you don't want to mess with your phone's settings, you can use external devices. Smart sockets with timer support or smart home integration allow you to automate the charging process. You can set up a scenario where the socket only supplies power at certain hours or cycles on and off.
For example, you can set the socket to run for 30 minutes every 30 minutes at night, and that prevents the battery from being constantly heated by the trickle charge, which is small but still loads, and it's a great way to extend the life of the battery without installing apps.
☑️ Setting up a smart socket
There are also special cables with built-in throttle or switch that physically limit the current to 1A. Such accessories can be found on marketplaces, they are the hardware analogue of using a weak power supply, but more convenient in transportation.
