How to enable fast charging on Xiaomi Redmi smartphones: the full guide 2026

Did you buy a new Xiaomi Redmi with fast charging support, but the smartphone persistently charges for 2-3 hours? Or did the MIUI update disappear the option of accelerated charging? This problem is familiar to many owners of Redmi Note 12, Redmi 13C, POCO X5 and other models of the brand. It is not always a faulty charger - often fast charging is simply turned off in the settings or blocked by the system.

In this article, we’ll look at all the ways to enable fast charging on Xiaomi Redmi, from basic MIUI settings to hidden engineering menus. You’ll learn how to check charging compatibility, why a smartphone can artificially limit current, and what to do if the feature is lost after an update. And a unique lifehack for models with a Snapdragon 8 Gen 1/2 processor, where fast charging is blocked due to overheating even at 20Β°C.

Why fast charging can be turned off by default

Charging control in Xiaomi is implemented on three levels: hardware (battery controller), software (MIUI) and user (settings). The manufacturer often limits the maximum current in the first days of using a new smartphone, this is called the "battery adaptation period", and fast charging automatically turns off in the following cases:

  • πŸ”‹ Battery temperature above 40Β°C or less than 5Β°C (thresholds depend on model).
  • πŸ”Œ Uses a non-original charger without support for Quick Charge protocols, PD Xiaomi Turbo Charge.
  • πŸ“± Power saving mode or "Ultra-Battery mode" is enabled in MIUI.
  • πŸ”„ The smartphone has undergone a recent update MIUI, After which the food was removed.
  • πŸ› οΈ Battery worn out by more than 30% (checked via #4636##).

For example, in the Redmi Note 11 Pro+ with the 120W HyperCharge, the system can limit power to 33W if you use a charge from POCO F4 (although both devices support Quick Charge 3+).

⚠️ Warning: If your Redmi suddenly stops supporting fast charging after falling or getting moisture, don't try to turn it on software. This can cause the power controller to fire.

How to check if your Redmi supports fast charging

Before you turn on the feature, make sure your Xiaomi Redmi model supports accelerated charging at all.The manufacturer often releases single-device modifications with different power controllers. For example, the Redmi 10 2022 has 18W and 33W charging versions with the same design.

Methods of verification:

  1. Xiaomi official website: Find your model under "Technical Specifications" and look for "Fast Charging" or "Maximum Charging Power".
  2. Device box: The original packaging usually has a Fast Charging or a specific value (e.g. 67W Turbo Charge).
  3. AIDA64: Install the app from Google Play. Go to the Battery section. See the charging technology line, which will show the protocol (QC 3.0, PD 3.0, Xiaomi Turbo Charge, etc.).

Method 1: Enabling fast charging via MIUI settings

The easiest method is to activate the function in the standard menu. The interface may vary depending on the version of MIUI (12/13/14) and the smartphone model.

For MIUI 14 (Android 13/14):

  1. Open Settings β†’ Battery and Performance.
  2. Slip on Battery Settings (or Additional).
  3. Find the Fast Charging option (can be called Turbo Charging or Accelerated Charging).
  4. Activate the slider. If the option is gray, check the charger you're using.

For MIUI 12/13 (Android 11/12):

  1. Go to Settings. β†’ Battery.
  2. Select Charging Mode or Charging Settings.
  3. Turn on Fast Charging. If you don't have a point, your model doesn't support the function.

For POCO Launcher: The path may be different. Try settings β†’ POCO features β†’ Battery.

Use the original Xiaomi RAM|Check the temperature of your smartphone (optimally). 10-35Β°C)|Turn off the power saving mode|Update. MIUI last-minute-->

⚠️ Note: On some models (Redmi) 9A, Redmi A1) The fast charging option is hidden if you use a non-original cable, even if you have a proprietary RAM, but a third-party cable, MIUI can block accelerated charging.

Method 2: Unlock through the Engineering Menu (for power users)

If MIUI doesn’t have a quick charger in its settings, but you’re sure your model supports it, you can try enabling the feature via the engineering menu, which works on the Redmi Note 10 Pro, Redmi K40, and other Snapdragon-powered devices.

Instructions:

  1. Open the phone app and enter the code: ##4636##
  2. In the menu that opens, select Battery Information.
  3. Check the current charging status (AC powered or USB powered).
  4. Go back to the main menu of engineering settings and select Hardware Testing β†’ Charging.
  5. Find the Fast Charge or Charge Control setting and set the Enable value.
  6. Reboot your smartphone.

On some firmware (e.g. MIUI EU), the path may be different. If the fast charge didn't work after the reboot, try resetting the battery settings:

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Click on the three dots in the upper right corner and select Show all processes.
  3. Find BatteryManager or com.miui.powerkeeper.
  4. Clear the cache and data, then restart the device.
What to do if the engineering menu is not opened?
If, after entering the code ##4636## Nothing is happening, it means that: 1. Your version. MIUI Blocks the engineering menu (often found on Chinese firmware). 2. Installed third-party software that intercepts USSD-codes (e.g. banking applications). 3. The device activates Child Mode or Corporate Profile Solution: Try entering code through Hidden Settings for MIUI (Available on Google Play or use it ADB-Command: Adb shell am start -n com.android.settings/.TestingSettings

Method 3: Use ADB-commands for compulsory inclusion

If standard methods don’t work, you can try enabling fast charging via ADB (Android Debug Bridge), which is suitable for advanced users and requires a computer with Xiaomi drivers installed.

Step-by-step:

  1. Download and install Google’s Platform Tools.
  2. Turn on USB Debugging on your smartphone: Go to Settings β†’ About Phone. Tap MIUI 7 times to activate Developer Mode. Go back to Settings β†’ Additional β†’ Developer. Enable USB Debugging.
adb devices

(Your device should be displayed).

adb shell settings put global fast_charge 1

Reset the device.

To check the current status, use the command:

adb shell settings get global fast_charge

If the result is 1 – fast charging is on, 0 – off.

adb shell dumpsys battery reset

This command resets battery statistics and can return factory charging settings.-->

Problems and Solutions: Why Fast Charging Doesn't Turn on

Even after all the manipulations, fast charging may not work, and let's look at the typical causes and ways to eliminate them:

The function disappeared after the updateResetting MIUI settingsReset settings through Settings β†’ System β†’ Reset settings β†’ Reset battery settings

If the battery capacity has fallen below 80% of the factory capacity, MIUI automatically limits the maximum charging current. You can check the wear and tear using the AccuBattery app or the engineering menu (#4636## β†’ Battery Information β†’ Wear level).

πŸ’‘

If your Redmi supports Quick Charge 4+ or PD 3.0 but charges slowly, try using a charger from a MacBook (20W/30W) or iPad (18W/20W) that is often better compatible with fast charging protocols than cheap "universal" adapters.

FAQ: Frequent questions about fast charging Xiaomi Redmi

❓ Why fast charging only works up to 80% and then slows down?
This is a normal MIUI behavior called "optimized charging." The system specifically reduces current after 80% to reduce battery wear. Shuts down in Settings β†’ Battery β†’ Charging settings β†’ Optimized charging.
❓ Can I use fast charging constantly?
Yes, but it shortens battery life. Recommended: Use fast charging only when you need to charge urgently. Use 10W-18W (standard RAM) for everyday charging. Do not keep your smartphone on charge after 100%.
❓ Why Redmi Note 11 Charges Slowly Even With Original RAM?
Probable causes: Power Saving Mode Activated (turn off in battery settings); Battery wear (check through AccuBattery); firmware problem (update MIUI to latest version); Power controller malfunctioned (diagnostics required).
