How to enable fast charging on Xiaomi: all the ways and nuances

Xiaomi smartphones support fast charging technology, but not all users know how to activate it correctly. Often, device owners face a situation where charging is slow, despite the presence of a powerful adapter. The reason may lie in the wrong settings, incompatible cable or even software limitations. In this article, we will discuss all the ways to enable fast charging on Xiaomi, from basic settings to hidden MIUI functions.

It's important to understand that fast charging isn't just an option on the menu, it's a complete solution that depends on three components: the power adapter, the cable, and the smartphone itself. For example, the flagship Xiaomi 13 Pro or Redmi Note 12 Turbo models support charging up to 120W, but only when using the original kit. If you connect the device to a laptop or a cheap power bank, the charging speed automatically decreases. Next, we'll detail how to get your Xiaomi to charge at its maximum capacity.

Checking the compatibility of the device with fast charging

Before you try to enable fast charging, make sure your Xiaomi model supports it. Not all smartphones of the brand are equipped with this feature – for example, budget devices of the Redmi A series or older Mi 8 Lite models are limited to the standard 10W. Below is a table with popular devices and their maximum charging power:

If your model is not in the table, check the specifications on the official Xiaomi website or in the documents attached to the device. Note: even if the smartphone supports 30W, but you use an 18W adapter, charging will go at a reduced speed. Also, some models (for example, Xiaomi 11T Pro) require special cable with support for high currents – a standard USB-C from the kit may not be suitable.

⚠️ Note: Using uncertified adapters with power above the declared power for your model can lead to overheating of the battery and reduce its life.

Method 1: Activate fast charging via MIUI settings

In most cases, fast charging on Xiaomi is enabled automatically when you connect a compatible adapter, but in some MIUI firmware, this option can be hidden or disabled by default, to activate it:

1. Open Settings → Battery and Performance.
2. Select Charge (on some models – Battery settings).
3. Find the option of Fast Charging or Turbo Charging and switch the slider to the position on..
4. If you don’t have an option, check the Additional section or Performance Mode.

On some devices (e.g., the POCO X5 Pro), the path may be different: Settings → Special Features → Additional → Fast Charging. If you don’t find an item on the menu, it may mean your model doesn’t support accelerated charging or a firmware update is required.

After activation, you will notice that when you connect the charger on the lock screen, the inscription “Fast Charging” or “Turbo Charging” will appear. If there is no inscription, but the smartphone is warming stronger than usual – most likely, the function works, but does not appear due to the features of the firmware.

Method 2: Use of the original adapter and cable

One of the most common cases where fast charging doesn't work is when you use non-original accessories, and even if you bought an adapter with a declared 67W power, it might not support Xiaomi protocol.

• 🔌 Power adapter: Must be original (in the smartphone box) or certified (with the Mi or Redmi logo) and must have the power to match or exceed the maximum charging power of your device.
• 🔗 Cable: Use only cables with support USB-C 2.0 or higher. Cheap cables often have thin veins that can't withstand high currents. Xiaomi's original cables are usually labeled as 5A.
• 🔋 Power source: Avoid charging from USB-port laptops, car adapters or power bank without support PD (Power Delivery).

Critical information: Adapters from other brands (such as Samsung or Apple) may fit physically but not activate fast charging due to differences in data exchange protocols. If you lose the original adapter, only buy certified accessories marked Mi Turbo Charge or Qualcomm Quick Charge 4+.

Method 3: Update firmware and reset settings

Sometimes fast charging doesn't work because of software errors in the MIUI firmware, which is especially true for devices that haven't been updated in a long time.

1. Check for updates: Settings → About phone → System update.
2. If there are updates, install them and restart the smartphone.
3. If the problem persists, try resetting the battery settings: Settings → Applications → Application Management → Three points (menu) → Resetting the application settings → Battery

On some models (such as the Xiaomi Mi 11) after major MIUI updates, fast charging can turn off automatically, in which case a full factory reset will help, but make sure to back up the data before you do so.

If none of these methods worked, it may be the hardware that is the problem, such as a damaged power controller or a worn-out battery, in which case we recommend you contact the Xiaomi service center.

Method 4: Enabling fast charging via engineering menu (for advanced)

On some Xiaomi models (especially older or custom firmware), fast charging can be activated via an engineering menu, which is only suitable for advanced users, as improper actions can lead to failures.

Instructions:

1. Open the phone app and enter the combination: ##4636##
2. In the menu that opens, select Battery Information.
3. Check the current charging status. If you have a Fast Charge, activate it.
4. On some firmware, you need to go to Settings → For developers → Debugging over USB and enable the option Allow imitation charging.

⚠️ Warning: Changing the settings in the engineering menu can cause the device to malfunction or even the power controller to fail!

If the engineering menu is not available, try to turn on the developer mode: Settings → About Phone → MIUI version (click 7 times). Then go back to Settings → Additional → Developer and find options related to charging.

Optimizing charging: how to extend the life of the battery

Fast charging is convenient, but it speeds up battery wear due to elevated temperatures. To make your smartphone last longer, follow these tips:

• 🔄 Partial charging: try to keep the charge level between 20% and 80%. Full discharge and charge up to 100% reduce battery life.
• ❄️ Avoid overheating: Do not use your smartphone while charging for games or videos.Remove the case if the device is warming up.
• 🕒 Night Charging: Activate Adaptive Charging in the Battery Settings – It slows charging after 80% if you sleep.
• 🔌 Quality accessories: Cheap adapters and cables can cause power surges that are harmful to the battery.

On models that support wireless charging (such as the Xiaomi 13 Pro), the speed is usually lower than that of wired charging, but battery wear is slower. If you charge wirelessly frequently, turn off fast charging in the settings - this will prolong the battery life.

💡

To check the battery status, type ##6484## in the engineering menu (on some models) or use the CPU-Z app to analyze charging cycles.

Frequent problems and their solutions

If fast charging on Xiaomi doesn’t work, here are the most common reasons and ways to fix them:

If neither of these methods worked, there may be a problem with the power controller or the battery itself, and in this case, we recommend you contact the service center, and remember that replacing the battery yourself can lead to a loss of warranty if the device is still in warranty service.

💡

Before visiting the service, check if the function "Optimized Charging" is activated on your device - it artificially slows down the process to save the battery.
