How to enable fast charging on Xiaomi: all ways + problem solving

Xiaomi smartphones (including Redmi and POCO sub-brands) support a variety of fast charging standards, from the branded MI TurboCharge to the universal Quick Charge (QC) and Power Delivery (PD). However, many users find that the device charges slowly, despite the presence of a compatible adapter, the reason is often due to software limitations or incorrect settings.

In this article, we’ll break down all the working ways to activate fast charging on Xiaomi, including hidden options in MIUI, ADB commands, and even hardware nuances. Separately, we’ll focus on common bugs (such as using unoriginal cables) and explain why sometimes your smartphone “refuses” to charge at full speed. If your Redmi Note 12 or POCO F5 charges too long, you’ll find a solution here.

1. Checking support for fast charging with your Xiaomi model

Before you try to enable fast charging, make sure your smartphone supports it. Xiaomi uses several standards depending on the model and year of release:

• 🔋 MI TurboCharge (up to 120 watts) – proprietary technology for flagships (Xiaomi 13 Ultra, Black Shark 5).
• ⚡ Quick Charge 3.0/4.0+ (before 30 W) — common in the Redmi Note series 10/11/12 and POCO X3/X4.
• 🔌 Power Delivery (PD) (Up to 67 watts – used in newer models (Xiaomi 14, Redmi) K60).
• ⚠️ No fast charging – budget models (Redmi) A1, POCO C50) limited to 10-18 W.

Check the maximum charging power can be:

1. On the official website of Xiaomi in the characteristics of the model.
2. In the AIDA64 appendix (Battery → Charge rate).
3. On the smartphone box (usually the maximum power of the adapter in watts is indicated).

💡

If your smartphone supports, for example, 33 watts, but the package was an adapter for 18 watts – buying a more powerful charger will speed up charging (provided that the protocols are compatible).

Important: Some models (like the Redmi Note 11 Pro+) support 120W with only the original Xiaomi adapter. Third-party chargers, even with the same power, can run slower due to lack of certification.

2. Enable fast charging via MIUI settings

In most Xiaomi smartphones, the fast charging option is activated by default, but sometimes it turns off after a MIUI update or reset.

1. Open Settings → Battery and Performance.
2. Choose Charging (or Fast Charging in older versions of MIUI).
3. Activate the Quick Charging Switch (if any).
4. In some models (POCO F3, Xiaomi 11T) additionally enable Smart Charging 5.0 – this optimizes speed without harming the battery.

If the Fast Charging item is not on the menu, it means:

• 📱 Your model does not support technology (see table above).
• 🔄 The option is hidden in the developer or requires activation through the ADB.
• 🔌 You are using a non-original cable/adapter (see section 4).

3. Hidden settings: Developer mode and ADB

On some Xiaomi models (especially custom firmware or global versions of MIUI), the fast charging option is hidden. To unlock it, you will need a developer or ADB team mode.

Method 1: through the developer menu

1. Activate Developer Mode: Go to Settings → About Phone and click on MIUI Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Find the option of Limit Charging or Fast Charging and turn it on.

Method 2: ADB teams

If you don’t have the option on the menu, use ADB (PC and USB debugging required):

adb shell settings put global fast_charge 1


adb shell settings put global mi_fastcharge_enable 1

For models with MI TurboCharge (e.g. Redmi Note 12 Turbo) do the following:

adb shell settings put global turbo_charge_enabled 1

Install Xiaomi drivers on PC|

Enable USB debugging in the developer settings |

Connect your phone to a PC with an unlocked screen |

Download. ADB Tools (platform-tools) from Google|-->

Note: after completing the commands, restart your smartphone. If charging has not accelerated, check the adapter compatibility (section 4).

4.Influence of cable and adapter on charging speed

Even if your smartphone supports 67W and everything is on, the cable or adapter can be a bottleneck.

• 🔌 Adapter: Must support the same or more power as a smartphone. POCO F4 GT (120W) needs a 120W adapter, not 33W.
• 📶 Cable: Cheap cables often limit current to 2–3 A. For fast charging, you need a cable with support USB-C 2.0/3.0 certification USB-IF.
• 🔄 Ports: charging through USB-The port of a laptop or car adapter is usually slower (max. 10-15 watts).

Check the real charging power can be using the applications:

• AccuBattery (shows current and voltage in real time).
• Ampere (displays charging speed in mA).

⚠️ Note: use of uncertified high-power cables (67W)+) may cause the heat to overheat. USB-C It's especially dangerous to charge a 120 watt smartphone with a cheap cable from a no-name brand.

5. Software limitations: why Xiaomi artificially slows charging

Xiaomi (like other manufacturers) sometimes limits charging speeds to extend battery life.

• 🌡️ Overheating: if the battery temperature exceeds 40°C, MIUI It automatically reduces current. That's normal -- that's how lithium-ion batteries protect themselves.
• 🔋 Battery wear: With a capacity below 80%, the system can limit charging to 10-15 watts.
• 📵 Background processes: active use of the smartphone during charging (games, video calls) reduces the speed.
• 🔄 Night exercise: in MIUI Optimized charging is a feature that slows down after 80% (to keep the battery from 100% overnight).

To disable the restrictions:

1. Go to Settings → Battery → Battery settings.
2. Turn off the optimized charging (if it interferes).
3. In Developer Mode, deactivate Background Limitation for Critical Applications.

💡

If the smartphone warms up while charging is not always a defect. Flagship models (for example, Xiaomi 13 Ultra) at 120 watts are heated to 45-50 ° C, but this is provided by the design (graphite heat sinks are used).

6.Fast charging on older Xiaomi models (until 2020)

Xiaomi 2018-2019 smartphones (Redmi Note 7, Mi 9, POCO F1) support Quick Charge 3.0/4.0, but often require additional configuration:

• 🔧 Enable Fast Charging in the Battery Settings (see Section 2).
• 🔌 Use a support adapter QC 3.0 (for example, from Redmi Note 8 Pro).
• 📲 Install a custom core (such as FrancoKernel) to overclock charging (for advanced users only!).

For models without official fast charging support (e.g. Redmi 5A), try:

1. Swipe a modified core (risk of brick!).
2. Use an adapter with PD 2.0 (up to 18 watts) – some devices recognize it as compatible.

⚠️ Warning: Firmware unofficial cores on older Xiaomi can lead to loss of warranty and battery overheating. On models with a battery capacity of less than 4000 mAh, fast charging reduces the life of 15-20%.

7. Problem Solving: Why Fast Charging Doesn't Work

If you have everything set up, but the smartphone still charges slowly, check:

If the problem persists, try:

1. Update MIUI to the latest version (new firmware fixes charging bugs).
2. Reset the settings to factory (Settings → About phone → Reset).
3. Check the battery for wear (see Health option in AccuBattery).
