Where to enable fast charging on Xiaomi: hidden settings and nuances for different models

Have you bought a new Xiaomi, Redmi or POCO smartphone, but the battery is charging too slowly? or has the option of accelerated charging disappeared after the MIUI update? This problem is familiar to many users - the manufacturer often hides the fast charging function in non-obvious menus or disables it by default "for safety." In this article, we will analyze exactly where fast charging on different Xiaomi models is turned on, why it may not work and how to avoid typical errors.

Not all Xiaomi smartphones support Quick Charge, Fast Charge or the branded HyperCharge. For example, the budget models of the Redmi 9A or POCO M3 are not physically able to charge faster than 10W, even if you turn on all possible settings. And flagships like the Xiaomi 13 Ultra or Redmi K60 Pro support power up to 120W — but only under the right conditions. We collected current data for 2026, including hidden chips MIUI 14/15 and bypassing restrictions for older devices.

1.How to check if your Xiaomi supports fast charging

Before you look for settings, make sure your device is physically capable of charging at higher power.

• 🔋 Supported models 33W and above: Xiaomi 12/13/14 series, Redmi K50/K60, POCO F4/F5, Black Shark 5. These smartphones are usually equipped with branded charging with markings MDY-12-XX (where XX — wattage).
• ⚡ Models with 18W–27W: Redmi Note 10/11/12 Pro, POCO X3/X4/X5 Pro, Mi 10 Lite. Here, fast charging is often turned off by default.
• ❌ No support: Redmi 9/10 (free of the Pro), POCO M3/M4, battery-powered ≤ 4000 Mach and Helio processor G35/G80.

To know the maximum charging power of your model:

1. Open the Settings app → About the phone → All the characteristics.
2. Find the line Maximum charging power (on new MIUI) or Charger Type (on older versions).
3. If this item is not available, check the box from the smartphone: the charging power is indicated next to the zipper symbol (for example, 33W Fast Charge).

Attention! If your smartphone supports, for example, 67W, but only 18W is displayed in the settings, this is not a mistake. Xiaomi artificially limits power when using non-original cables or adapters.

2. Where fast charging is enabled: step-by-step instructions for MIUI

Depending on the firmware version, the path to settings may vary, and we have compiled the latest versions for MIUI 12-15 (including global and Chinese builds).

Method 1: Basic battery settings (for most models)

1. Go to Settings → Battery and Performance.
2. Slap the icon. ⚡ Next to Charge (or select Charge Settings).
3. Activate the Fast Charging switch (could be called Accelerated Charge or Quick Charge).
4. If you have the option of Superfast Charging (for models with 67W/120W), turn it on separately.

Method 2: Through a Hidden Menu of Engineering Settings (for Older MIUIs)

On MIUI 11 and below, the fast charging option is sometimes hidden to find it:

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 item – turn it on.
4. Reset the device.

Original Xiaomi cable and adapter

Charging from the socket (not from the USB-port)

Power saving mode is off.

Battery temperature in the range of 10–40°C-->

Attention! On some models (Redmi Note 8 Pro, POCO X3 NFC) after turning on fast charging through the engineering menu, overheating protection may work. If the smartphone starts to warm up a lot, return the settings to the factory settings.

Method 3: For smartphones with HyperCharge (120W)

The flagships Xiaomi 11T Pro, Redmi K50 Gaming and newer support the technology HyperCharge, but it works only under strict conditions:

• 🔌 The original set (cable) is used. + box-mount.
• 🌡️ Battery temperature below 35°C (when overheating, the power automatically decreases to 33W).
• 📱 Battery level from 1% to 80% (after 80% the speed drops to save battery life).

To activate HyperCharge:

1. Connect the original adapter to the socket.
2. Insert the cable into the smartphone – a notification should appear: HyperCharge (120W) is used.
3. If there is no notification, check the settings in Settings → Battery → Charging settings → HyperCharge Mode.

3. Why fast charging doesn't work: top-5 cause

You've turned on all the settings, but the smartphone is still charging slowly? Here are the most common problems and solutions:

A critical nuance: if you use wireless charging (even the original from Xiaomi), the maximum power rarely exceeds 20W. To get 30W+, you must connect via cable.

💡

If the smartphone warms up during fast charging, try charging it in the aircraft mode - this will reduce the load on the processor and reduce heating.

Charger compatibility: what can be used

One of the big myths is that "any 30W adapter is good for Xiaomi," and Xiaomi actually uses fast charging protocols that aren't always compatible with universal charging.

• ✅ Recommended: Original Xiaomi Adapters with Labeling MDY-12-XX (for example, MDY-12-ED for 33W).
• ⚠️ Limited Compatibility: Realme Dash Charge, Oppo VOOC — It will work, but the power may be reduced to 18W.
• ❌ Incompatible: Samsung adapters AFC (max. 15W), Huawei SuperCharge (requires a special protocol).
• 🔄 Universal solutions: charging with support PD 3.0 (e.g. Anker) 65W) — It will only work at full capacity with the cable. USB-C to USB-C.

Pay special attention to the cable! Even if the adapter supports 67W, but the cable is designed for 10W - fast charging will not. Xiaomi's original cables are labeled MDY-08-XX (where XX is length in centimeters).

5.Fast charging and battery health: how to minimize wear and tear

Many users are afraid to turn on fast charging, fearing that it will kill the battery in a year. Yes, high power accelerates battery degradation, but only if used incorrectly.

• 🔄 Alternate modes: use fast charging only when you need to recharge urgently. For night charging, turn it off.
• 🛑 Avoid 100%: Turn off the smartphone from charging at 80-90%. Full charge to 100% under high power reduces battery life by 20-30%.
• 🌡️ Control the temperature: if the body is heated above 40°C – interrupt the charge for 10-15 minutes.
• 🔋 Calibrate the battery: once every 2-3 months, discharge the smartphone to 0% and charge up to 100% without interruptions (only on slow charging!).

Attention! Xiaomi smartphones with MIUI 13+ have a hidden function Adaptive Charging, which automatically limits power when charging for long periods (for example, at night).

1. Go to Settings → Battery → Charging settings.
2. Turn on Adaptive Charging (or Optimized Charging) switch.
3. Set a schedule (for example, from 23:00 to 7:00) so that the smartphone itself adjusts the current.

💡

Using fast charging at temperatures below 10°C or above 45°C can cause permanent battery damage, and MIUI automatically reduces power to 5W.

Fast charging on older models: bypassing restrictions

If you have a Xiaomi smartphone from 2018 to 2020 (e.g., Redmi Note 7, Mi 9, POCO F1), the manufacturer could artificially limit the charging power through the firmware.

Method 1: Change the firmware region

On some models (e.g. Redmi Note 8 Pro), fast charging is only available in Chinese or global firmware, but is not available in the EU version.

1. Download the firmware archive for your region from en.miui.com.
2. Go to Settings → About the phone → System update.
3. Slap the icon. ⚙️ in the upper right corner and select Select the Service Package.
4. Specify the path to the downloaded file and wait for the installation.

Method 2: Use the ADB-Teams (for advanced users)

If you do not have a fast charging option in the settings, you can force it to activate via ADB.

1. Install Platform Tools on your PC.
2. Connect your smartphone over USB and enable debugging over USB in Settings → For developers.
3. Enter in command line: adb shell settings put global fast_charge_forced_enable 1
4. Reset the device.

Warning: Incorrect use of ADB can cause malfunctions in the smartphone. If after executing the command, the device begins to overheat or discharge quickly, return the settings to the factory:

adb shell settings put global fast_charge_forced_enable 0

7. Frequent questions about fast charging on Xiaomi

💡

Even if your smartphone supports 67W, the actual charging speed depends on temperature, charge level and cable used, and on average, the battery charges up to 50% in 15 minutes, and up to 100% in 40-50 minutes.
