Xiaomi fast charging: how to turn on and configure correctly

Xiaomi smartphones are famous not only for affordable prices, but also for advanced technologies — one of them is fast charging. However, many users face a situation where the device charges slowly, despite the support of the feature. The reason is often the wrong settings or incompatible accessories. In this article, we will discuss how to enable fast charging on Xiaomi, which models support it, and what to do if the technology does not work.

It's important to understand that even if your smartphone is equipped with Quick Charge, Turbo Charge or HyperCharge, the default feature can be turned off to save battery life. The manufacturer often hides this option in the depth of the menu, and sometimes its activation requires additional manipulation, we will consider all possible ways, from standard settings to hidden modes for power users.

What Xiaomi models support fast charging

Not all Xiaomi devices are equipped with fast charging technology, the function depends on the model, firmware version and even the region of sale. Below is a table with the current data on the popular series (2026):

Note: Even if your model is on the list, charging power may be limited due to:

• 🔌 Use of unoriginal cable or power supply.
• 📱 An outdated firmware version (MIUI 13).
• 🔋 Battery temperature (when overheating or cold, the function is turned off automatically).
• 🛠️ Hardware restrictions (for example, after battery replacement).

To find out exactly whether your smartphone supports fast charging, check the specifications on the official Xiaomi website or in the Settings → About Phone → Features.

Standard way to enable fast charging

On most Xiaomi devices, the function is activated via the settings menu.

1. Open Settings (the gear icon on the main screen).
2. Go to the Battery and Performance section.
3. Select Charge or Quick Charge (name depends on MIUI version).
4. Activate the switch next to the option to Enable Fast Charging.

If there is no such clause, it means:

• 📵 Your model does not support technology (check the table above).
• 🔄 The function is enabled by default (on some devices it is activated automatically when a compatible unit is connected).
• 📲 You have an old firmware (update) MIUI through settings → The phone. → Updating the system).

Check the smartphone model for compatibility |

Update MIUI to the latest version|

Use the original cable and power supply |

Connect the charger to the 220V | network

Make sure the battery temperature is between 10 and 40.°C-->

On some devices (e.g. Redmi Note 12 Pro+), the option is hidden deeper, in which case the path will be: Settings → Additional → Special Features → Charging Optimization. There you need to turn off Adaptive Charging mode, which limits speed to extend battery life.

Hidden settings: how to enable fast charging through the engineering menu

If the standard method didn't work, you can try activating the function through the engineering menu, which is suitable for power users and requires caution!

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information.
3. Scroll down and find the Fast Charge or Quick Charge.
4. Click on it and select Enable (enable).

⚠️ Note: Not all models support this method. Some devices may not have an engineering menu or have a different interface. If nothing happens after you enter the code, then your smartphone does not support this method.

Alternatively, use the MTK Engineering Mode app (for MediaTek processors):

• Download the app from Google Play.
• Open it and go to the Hardware Testing → Charging section.
• Activate the Fast Charging option.

Why fast charging doesn't work: common problems

Even if you turn on the feature, the smartphone can charge slowly.

Pay special attention to cable: cheap uncertified wires often do not support high currents. Xiaomi’s original cables are labeled 5A or 6A, which indicates support for fast charging.

Another common reason is the power saving mode, and if it's on, the smartphone automatically limits the charging power.

1. Go to Settings → Battery and Performance.
2. Select Power Saving Mode.
3. Turn off all restrictions or select Performance mode.

💡

If the smartphone charges slowly at low temperatures (like in winter outdoors), don't panic - that's OK. Lithium batteries don't take cold well and the system automatically reduces current for safety.

How to Check if Fast Charging Really Works

Many users think their smartphone is charging fast, but the power is actually limited to know the current charging speed:

1. Connect your smartphone to the charger.
2. Open the Ampere app (available on Google Play).
3. See the value in the Charging section (e.g. 3.5A/18W).

Normal indicators for fast charging:

• 🔋 Quick Charge 3.0/4.0: 18–30 Watt (3–4.5A).
• 🔥 Turbo Charge (67W): 4.5–5A 10–12V.
• ⚡ HyperCharge (120 W): 6A upon 20V.

If the values are lower, it means that the function is not activated or there are problems with hardware, and you can also use standard MIUI tools:

1. Get the charger on.
2. Unlock the screen – the top notification bar will show the words “Fast Charging” or “Turbo Charging”.
3. Click on the notification to see the current power.

Important: On some models (such as the Xiaomi 13 Ultra), fast charging only works when the screen is off. If you are actively using the phone while charging, the speed can drop to the standard 10-15 watts.

Safety: Myths and Real Risks of Fast Charging

Many users are afraid to use fast charging, fearing for the health of the battery, let's understand what is true and what are myths.

Myth 1: “Fast charging kills the battery in six months.”

Reality: Modern Xiaomi smartphones are equipped with controllers that regulate current and voltage. When used correctly (original accessories, no overheating), the battery life is reduced slightly - by 5-10% in 2-3 years.

Myth 2: “You always have to charge to 100%.”

Reality: Lithium batteries are better kept in the range of 20-80%, MIUI has an Optimized Charging feature that automatically stops the process by 80%.

1. Go to Settings → Battery and Performance → Battery Settings
2. Activate the optimised charging option.

⚠️ Warning: If you notice that the battery is swollen, the phone is overheating even without a load, or battery life has dropped dramatically - immediately turn off fast charging and contact the service center.

Another important point is the compatibility of chargers, for example, the power supply from the POCO F4 (67 watts) may not give full power to the Redmi Note 11 (33 watts), because the charging protocol is different. Always use the unit recommended for your model.

Alternative ways to accelerate charging

If your smartphone doesn’t support fast charging, but you want to speed up the process, try these methods:

• ⚡ Aircraft mode: Disconnects all radio modules (Wi-Fi, 4G, Bluetooth, reducing power consumption. Charging is 10 to 15 percent faster.
• 🔌 Turning off the phone: When switched off, the smartphone charges 20-30% faster, as it does not waste energy on background processes.
• 🧊 Cooling: Put your phone on a metal surface or use a cooling stand. at temperatures below 30°C charging is more efficient.
• 🔄 Disable applications: Close all active programs through Settings → Annexes → Launched.

You can also use wired charging instead of wireless charging. Even if your Xiaomi supports Qi charging (like the Mi 11 or Xiaomi 13), the wireless method is always slower – a maximum of 50 watts versus 120 watts on cable.

For devices that support Reverse Charging, you can try connecting another gadget (such as headphones) and charging your phone at the same time, but this method is ineffective and more suitable for emergencies.

💡

The most reliable way to speed up charging is to use the original power supply and cable, and turn off the phone or put it into airplane mode.
