How to turn off turbocharging on Xiaomi smartphones: safe ways

Why users want to turn off fast charging on Xiaomi

Turbocharging (or Fast Charging) has become a standard option for most modern Xiaomi smartphones, including the Redmi line, POCO and flagship models, which the manufacturer has positioned as a key advantage: in 30 minutes, the battery can charge 50-70%, but this technology has a downside, which is rarely talked about in advertising materials.

Many Xiaomi owners are faced with a situation where the battery begins to “degrade” faster than expected – the capacity drops after a year of active use, not only due to natural wear, but also to overheating the battery during intensive charging. Turbocharging increases the temperature of the battery to 40-45 ° C, which accelerates the chemical processes inside lithium-ion cells, as a result of 300-500 charging cycles, the capacity can decrease by 20-30%.

Another reason to disable Fast Charging is compatibility issues: Non-original chargers or low-quality cables can conflict with the fast charging protocol, causing disruptions or even damage to the power controller. Finally, some users simply prefer slow charging at night to reduce the load on the network and extend the life of both the battery and the power supply.

Official and unofficial ways to disable turbocharging

Xiaomi doesn’t always provide a direct option to deactivate fast charging in settings. However, there are several proven methods that work on most models released after 2019. It’s important to understand that not all methods are universal – their effectiveness depends on the version of MIUI and the hardware platform.

We will discuss three main approaches:

• 📱 Through hidden settings MIUI (It works with most models with MIUI 12+)
• 🔧 With the help of the engineering menu (requires caution, suitable for advanced users)
• 🛠️ Hardware restriction (use of non-original chargers with reduced power)

Before you start settings, make sure your smartphone is at least 30% charged, which will prevent a sudden shutdown during changes, and we also recommend backing up your data if you plan to use the engineering menu.

Method 1: Disabling turbocharging via MIUI settings

The safest and easiest method is to use built-in MIUI options. Unfortunately, it is not available on all models. For example, on Xiaomi 11T Pro or Redmi Note 10 Pro, the path to settings may be different from the POCO F3 or Mi 11 Lite. We will look at the universal algorithm that works on most devices with MIUI 12-14.

Step instructions:

1. Open the Settings app (the gear icon on the home screen).
2. Go to Battery and Performance (on some models, just Battery).
3. Slip on Battery Settings or Additional (depending on the firmware version).
4. Find the option Quick Charge (can be called Turbo Charge or Quick Charge).
5. Switch the slider to the off position.

If you don’t see this, try an alternative route:

1. Go to Settings. → The phone.
2. Tap the MIUI version several times until you become a developer!
3. Go back to the main settings menu and open a new section for developers.
4. Find the option to Limit charging current or Slow charging mode.

Important! On some models (such as the Xiaomi 12 Pro or Redmi K50), the fast charging option can be locked at the firmware level, in which case you will have to use an engineering menu or hardware methods.

Method 2: Engineering menu (for advanced users)

If the standard settings do not allow you to disable Fast Charging, you can use the Engineering Mode, which requires care, since improper actions can lead to malfunctions of the device, and we recommend it only to those who are confident in their abilities or ready for possible risks.

Algorithm of action:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information.
3. Scroll down and find Fast Charge Config or Charging Control.
4. Change the value from Enabled to Disabled.
5. Save the changes and restart the device.

On some models (e.g. POCO X3 Pro) the path may be different:

Engineering Menu → Hardware Testing → Charging → Set Charge Current

Warning: If the phone stopped charging at all after the changes, return the settings to the original state or reset via Recovery Mode.

Method 3: Hardware charging restriction (no changes in settings)

If the software methods didn't work, or you don't want to risk settings on your phone, you can take a different path, which is to limit the power of the charger, which requires no firmware intervention, and is completely safe, but has its own nuances.

You'll need:

• 🔌 Power charger 5W–10W (standard USB-Computer port or old iPhone charger)
• 🔗 Cable USB 2.0 (without support for fast data transfer)
• ⚡ USB-concentrator (optional, for additional current restriction)

How it works:

• Xiaomi’s standard charger outputs 18W-120W depending on the model, and if you plug the phone into a 5W source, the battery controller automatically switches to slow charging.
• USB 2.0 cables have a smaller conductor cross section, which limits current to 0.5A-1A.
• USB-Hubs often reduce power output, which also slows charging.

Cons of the method:

• ⏳ Full charging time will increase to 4-6 hours (instead of the standard 1-1.5 hours).
• 📉 Some models (Xiaomi 13 Ultra, Redmi) K60 Pro) may ignore weak power supplies and refuse to charge.

💡

If you charge your phone frequently at night, use a smart timer socket, set it to shut down 2-3 hours after charging, which is enough time to charge the battery 80-90% without overheating.

Xiaomi models on which turbocharging cannot be turned off

Despite all efforts, some Xiaomi smartphones do not allow you to deactivate fast charging either through settings or through the engineering menu, due to the manufacturer's policy or the features of the hardware platform. Below is a table of models where Fast Charging is hard-stitched into the firmware:

If your model is on this list, there are two options:

1. Use hardware constraint (weak charger).
2. Install custom firmware (such as LineageOS or Pixel Experience) where charging settings are more flexible.

💡

On models with support for 120W (for example, Redmi K50 Gaming), even a partial shutdown of turbocharging can lead to errors of the power controller, in which case it is better to use the original charger at reduced power (via an adapter).

What happens if you use slow charging all the time?

Moving to conventional charging has both pros and cons, so let's figure out what to expect in the long run.

Advantages:

• 🔋 Extending battery life by 20-40% (when used correctly).
• 🌡️ Reducing the heat of the device during charging (especially relevant for gaming smartphones).
• 💡 Less load on the power supply, which prolongs its life.

Disadvantages:

• ⏳ Increase in charging time by 2-3 times.
• 🔌 Inconvenience in the urgent need to replenish the charge.
• ⚠️ Risk of battery becoming accustomed to low currents (in rare cases).

Critical point: If you use non-original batteries (for example, after replacement), slow charging can lead to undercharging due to a mismatch of controllers, in which case it is recommended to perform a full charge-discharge cycle at least once a month using the original charger.

Frequent Mistakes and How to Avoid Them

When you turn off turbocharging, you often have typical problems, and we've collected the most common ones and the ways to solve them.

⚠️ Warning: If the phone stopped charging at all after Fast Charging was turned off, check the integrity of the cable and power supply. 90% of the time the problem is the damaged one. USB-connector or oxidized contacts.

Error 1: Settings are reset after rebooting

This is typical for devices with MIUI 13+, where some of the parameters of the engineering menu are not saved.

• Use the QuickShortcutMaker app to create a shortcut to direct access charging settings.
• Set up automatic execution ADB-commands when loading (root access required).

Error 2: The phone is charged or shut down.

It's usually caused by an unstable power source.

• Whether you use the original cable (non-original cables may not support the required protocols).
• Is the device connected to USB-hub.
• Is there any damage to the connector (dust, dirt, mechanical defects).

Error 3: Battery discharges faster after turbocharging is turned off

This is a temporary effect, which is associated with recalibrating the controller, to correct the situation:

1. Completely discharge the phone before turning off.
2. Charge it to 100% without interruptions (use the original charger).
3. Repeat the cycle 2-3 times.
