Disabling turbocharging on Xiaomi: when to do it and how to do it right

Fast charging has become the standard for modern Xiaomi smartphones, but not always that advantage. Many users face situations where turbocharging is not only unnecessary, but also damages the battery. For example, if you leave your phone on overnight charging or use non-original adapters, accelerated charging can lead to overheating and accelerated wear and tear of the battery.

In this article, we will discuss how to completely or partially disable fast charging on Xiaomi, Redmi and other devices. POCO — We'll look at official methods through settings, hidden engineering menus, and alternative ways for advanced users, and we'll focus on the consequences of such a disconnect and when it's really justified.

It is worth clarifying right away: the manufacturer does not recommend turning off turbocharging for no good reason. However, in some scenarios (for example, when using the phone as a powerbank or when charging from weak sources), this can be useful.

Why you may need to turn off turbocharging

At first glance, fast charging is always a plus, but there are a few scenarios where it's justified to turn it off:

• 🔋 Extending battery life: Lithium-ion batteries degrade faster at high currents and temperatures. Turbocharging increases heating, which reduces battery life by 15-20% in 2-3 years.
• ⚡ Using non-original adapters: Cheap chargers may not be able to handle high currents, causing the cable to overheat or even catch fire.
• 🌙 Night charging: If the phone stays on charge all night, fast charging first heats the battery and then maintains 100% charge -- double the stress for the battery.
• 🔌 Charging from weak sources. USB-In this case, the turbocharging just won't work, but the phone will constantly try to activate it, which can lead to malfunctions.

In addition, some users note that when you turn off fast charging, the phone heats up less during games or heavy use, because the system does not waste resources on managing high currents.

Important: If your Xiaomi smartphone is older than 2-3 years, turning off turbocharging can actually extend the battery life. For new devices, the difference will be less noticeable, but still positive.

How to check if turbocharging is on your Xiaomi

Before you turn off fast charging, make sure it’s really active. On Xiaomi devices, you can check this in a number of ways:

Visual indication:

Connect the original fast-charging adapter (usually bundled with flagships or models of the Redmi Note series).

On the lock screen or in the status bar, a notification such as Quick Charging, Turbo charging or Fast charging should appear.

- On some models (for example, Xiaomi 13 Pro or XP) POCO F5) The charging indicator changes color from green to orange.

2. Through battery settings:

- Go to Settings. → Battery.

- Click on the icon. ⚡ near-consumption schedule.

- In some firmware (MIUI 14+) This shows the current charging mode.

3.Using the engineering menu (for advanced users):

Enter the number ##4636##.

Go to the Battery Information tab.

- Look at the parameters. AC Powered and Charge type: If it says Fast charge or Turbo charge, it means that the mode is active.

On models with HyperCharge support (for example, Xiaomi) 11T Pro or Redmi Note 11 Pro+ 5G) The indication may be different – look for HyperCharge or Extreme charging labels.

Official method: disabling through MIUI settings

The easiest and safest method is to use built-in options. MIUI. Unfortunately, not all Xiaomi models have this item available, but most mid-range and premium devices have it.

Instructions:

1. Open the Settings.
2. Go to Battery and Performance (on some firmwares, just Battery).
3. Find Quick Charging or Charging Mode (may be in the submenu Additional or Battery Settings).
4. Turn off the switch next to Quick Charging or select Standard Charging mode.

On certain devices (e.g, POCO X3 Pro or Redmi K40) The path may be slightly different: → Battery → Settings (⚙) → Fast charging.

⚠️ Note: On budget models (e.g. Redmi) 9A or POCO C31) There may be no option to turn off fast charging, in which case alternative methods will have to be used (see the following sections).

Hidden methods: engineering menu and ADB-team

If the settings do not have the option to turn off fast charging, you can try more advanced methods. They require caution, as improper actions can lead to malfunctions of the device.

Method 1: Engineering menu (MTK-chip)

On smartphones with MediaTek processors (for example, Redmi Note 10, POCO M4 Pro) an engineering menu may be used:

1. Open the dialer and type ##36446337## (or #4636## on some models).
2. Go to the Battery Information tab.
3. Find the Fast Charge Config or Charge Control option.
4. Change the value to Disable or Standard Charge.

Method 2: ADB-Teams (for all models)

This method works on any Xiaomi devices, but requires a connection to a computer and enable debugging. USB.

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your phone to your PC, open the command line (Windows) or terminal (Mac/Linux) and enter adb shell su echo 0 > /sys/class/power_supply/battery/fast_charge_enabled
4. Reset the device.

⚠️ Note: After updating the firmware settings of the engineering menu or ADB They can also be dropped on some models (Xiaomi). 12, 13) access fast_charge_enabled may be blocked.

If ADB-The team didn’t work, so try an alternative:

adb shell settings put global fast_charge 0

Please note that this method does not work on all versions. MIUI.

Alternative methods: limiting current without turning off turbocharging

If you don't want to turn off fast charging completely, you can go another way, which is to limit the maximum current, which will reduce battery heat, but it won't shut it down completely.

Method 1: Use of a non-original adapter

The fast charging is activated only when a compatible adapter is connected. 5V/1A or 5V/2A, the phone will automatically go to standard mode, even charging from an old iPhone or a regular one will do. USB-port.

Method 2: Applications for charging control

Google Play has utilities that allow you to limit the charging current.

• 📱 AccuBattery – analyzes battery status and can limit charge to 80%, which reduces heating.
• ⚡ Battery Charge Limit – allows you to set a charge limit (for example, 90%), which indirectly reduces the load.
• 🔧 Kernel Adiutor (requires root) – gives access to fine core settings, including current restriction.

⚠️ Note: Applications without root rights may not work smoothly, for example, AccuBattery does not block fast charging, but only notifies it to activate. ADB.

Method 3: Charging in the off state

Some users have noticed that when charging a phone that is turned off, fast charging is slower, which is because the system doesn't activate full power without the screen on, but this method doesn't guarantee a reduction in current, depending on the model.

💡

If you often leave your phone charging overnight, set a charge limit of 80-90% through AccuBattery, which will significantly reduce battery wear without completely shutting down turbocharging.

Table: Compatibility of disconnection methods with popular Xiaomi models

If your model is not in the table, try universal methods (ADB On new devices (Xiaomi 14, Redmi Note 13), access to settings may be limited, in which case only the use of non-original adapters or applications remains.

Consequences of turning off turbocharging: pros and cons

Before you make a decision, weigh the pros and cons. Disabling fast charging has both obvious advantages and hidden disadvantages.

Pros:

• ✅ Extending battery life by 20–30% with regular use (confirmed by Battery University tests).
• ✅ Reduced phone heat during charging and playing.
• ✅ Safety with non-original adapters.
• ✅ Less stress for the power controller, which reduces the risk of hardware failures.

Cons:

• ❌ Increase in charging time by 1.5-2 times (from 1 hour to 2-3 hours with full discharge).
• ❌ Possible Firmware Failures During Use ADB or engineering menu (rarely, but sometimes).
• ❌ Automatic activation after updating - you will have to repeat the procedure.
• ❌ Reduced convenience if you are used to quickly recharge before leaving.

💡

Turning off turbocharging is justified if you charge your phone overnight or use it as a powerbank, otherwise limiting the charge to 80-90% via AccuBattery is enough.

If you still decide to turn off fast charging, we recommend periodically (every 1-2 months) return the standard settings and completely discharge / charge the battery.

Frequent Mistakes and How to Avoid Them

When you turn off turbocharging, users often face typical problems, and here are the most common ones and how to solve them:

1. After shutting down, the phone still charges quickly

This can happen for several reasons:

- You used the wrong one. ADB-code (check the correctness of the command).

The firmware reset the settings (try repeating the procedure).

- The adapter supports Qualcomm Quick Charge, which is activated separately. In this case, try another adapter (for example, on the computer). 5V/2And).

2.The phone stopped charging at all

If you have to use the engineering menu or ADB charging stopped:

- Reset the device.

- Check the cable and adapter.

- Reset settings through Settings → System system → Resetting settings → Resetting network settings (does not delete data).

- In extreme cases, reset to factory settings.

3. The battery started to run out faster.

This is a temporary effect associated with recalibrating the controller. Give the phone 2-3 full charge/discharge cycles, and the situation will normalize. → Battery → Battery utilization.

4. Heats up even when the turbocharger is turned off

Possible causes:

Background processes (games, updates, viruses).

- Damaged battery (check bloating).

Faulty power controller (diagnosis is required at the service center).

⚠️ Warning: If after disabling the turbocharger, the phone begins to behave unstable (spontaneous restarts, shutdowns), immediately return the standard settings and contact the service.

💡

If you are not sure about your actions, before experimenting with ADB or engineering menu make a backup of the data through Settings → System system → Backup.
