How to turn on fast charging mode on Xiaomi: a complete guide with photos and tips

Xiaomi smartphones are famous not only for their affordable price, but also for advanced charging technologies, from Quick Charge 3.0 to the branded HyperCharge at 120 watts. However, many users face a situation where the device charges slower than the manufacturer promises. The reasons can be several: from disabled settings to incompatible charger. In this article, we will discuss all ways to activate fast charging on Xiaomi, Redmi and POCO smartphones, including hidden MIUI settings, checking equipment and solving typical problems.

It’s important to understand that even Xiaomi’s flagship models (like the Xiaomi 14 Ultra or Redmi K70 Pro) can default to limit charging speeds to extend battery life. The manufacturer often hides these options in the depths of the menu or associates them with additional terms (like using the original cable).

This article is relevant for all devices on MIUI 12-14 and HyperOS, including models with support for 33W, 67W, 120W and 200W charging. If your smartphone is not included in this list, it is no problem: at the end of this article we will give a compatibility table and alternative methods for accelerating charging.

1. Compatibility Check: Does your Xiaomi support fast charging?

Before you try to turn on the fast charging mode, make sure your device supports it. Xiaomi often releases different modifications of the same model for different markets - for example, the Redmi Note 12 Pro in China can have 120W charging, and the global version only 67W.

To check the maximum charging power of your smartphone:

  • πŸ” Check out the features on the official website mi.com (select the region "Global" or "Russia").
  • πŸ“± Enter the model in the search engine with the request "model" + fast charging spec” (e.g. Xiaomi) 13T Pro fast charging spec).
  • πŸ› οΈ Use applications like this. AIDA64 or CPU-Z β€” In the Battery section, support for Quick Charge will be provided, PD (Power Delivery or Xiaomi proprietary technology.

2.The main method: enable fast charging in the MIUI settings

On most Xiaomi devices, the fast charging mode is activated via the hidden menu of the battery lab. MIUI 12-14 and HyperOS:

  1. Open the Settings. β†’ Battery.
  2. Slap the icon. βš™οΈ ("Battery settings") in upper right corner.
  3. Select Charging Mode (on some firmwares – Charging Optimization).
  4. Activate the Fast Charging or Accelerated Charging switch.
  5. If you have the option HyperCharge or Turbo Charging, turn it on.

On some models (for example, Xiaomi 12S Ultra) the path may be different:

Settings β†’ Additional settings β†’ Battery Laboratory β†’ Charging Mode

Use the original cable and power supply

Close the background applications (especially games)

Turn off the power saving mode

Check the battery temperature (should be 15-35Β°C)

Connect the charging to the socket, not USB-port-->

Once activated, you will see a notification "Fast Charging is on" in the status bar. If it is not activated, check:

  • ⚑ Power supply: should support PD Quick Charge 3.0+ (power 30W).
  • πŸ”Œ Cable: Original or Certified USB-C to USB-C high-current.
  • πŸ“± Temperature: If the battery is overheated (>40Β°C) or supercooled (<10Β°C), charging is automatically limited.

πŸ’‘

To check the actual charging power, install the AccuBattery app (showing current in mA) or Ampere app (showing voltage and amperes in real time).

3. Hidden settings: how to unlock maximum power

The manufacturer often limits the default charging speed to extend the battery life, but these limitations can be removed through an engineering menu or a battery life. ADB-team.

Method 1: Engineering menu (for advanced users)

This method works on most Xiaomi devices with Qualcomm processors:

  1. Open the Phone app and type ##4636##.
  2. Go to the section Information about the battery.
  3. Tap it on. AC charge current and set a maximum value (e.g., 5,000 mA for a 120W-charging).
  4. Save the settings and restart the device.
What happens if you set the current too high?
If the current is exceeded, the power controller protection may work for your model, which will cause charging to be turned off or overheated; on some devices (for example, the POCO F4 GT), this can even cause an emergency shutdown; we recommend increasing the current gradually, observing the battery temperature.

Method 2: ADB-teams (no root rights)

If the engineering menu is not available, use ADB:

  1. Install Platform Tools on your PC.
  2. Turn on USB debugging in the developer settings (Settings β†’ About Phone β†’ MIUI version – tap 7 times).
  3. Connect your phone to your PC and execute the command: adb shell settings put global fast_charge_forced_enable 1
  4. For models with HyperCharge add: adb shell settings put global hyper_charge_enabled 1

⚠️ Note: Not all models support forced fast charging via ADB. On some devices (such as the Redmi Note 11), this can cause charging settings to reset after rebooting.

4.Problems and Solutions: Why Fast Charging Doesn't Work

Even after you turn on all the settings, charging can remain slow. Let's consider the typical causes and ways to eliminate them:

Problem.Possible causeDecision
Charging goes to 10W instead of 33W+Unoriginal cable/power supply unitUse a complete RAM or a certified RAM (e.g. Anker 735)
The phone is warming up and slowing down.Background processes or high ambient temperatureClose the applications, reduce the brightness of the screen, remove the case
Fast charging only works up to 80%The option "Optimized charging" is enabledTurn off the settings β†’ Battery β†’ Battery settings
The RMS is not defined as β€œrapid”A USB-C port or cable is damaged.Check the cable on another device, clean the port of dust

If the problem is not solved, try resetting the charging settings:

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Find the battery and clear the cache.
  3. Turn off the phone from charging, wait 1 minute and plug it back in.

πŸ’‘

On HyperOS devices (such as Xiaomi 14), fast charging can automatically turn off when using uncertified accessories.This is due to the new Xiaomi Safe Charge protection system, which blocks high currents on non-original RAMs.

5. Alternative methods of accelerating charging

If your smartphone doesn’t support fast charging or you want to further optimize the process, use these tips:

  • ⚑ Aircraft mode: Disables all radio modules (4G, Wi-Fi, Bluetooth, reducing charging time by 15-20%.
  • πŸ”„ Background Disconnect: Close all applications through Recent or use Memory Optimization in Settings.
  • 🌑️ Cooling: Put your phone on a metal surface or use a cooling stand (e.g. Baseus Cooler).
  • πŸ”‹ Battery calibration: discharge the phone to 0%, then charge to 100% without interruptions (repeat 2-3 times).

For devices with support for reverse wireless charging (for example, Xiaomi 13 Pro), you can use dual turbo charging:

  1. Connect your phone to a 67W+ wired memory.
  2. Put another Qi-enabled device on the back (e.g., Xiaomi Buds 4 Pro headphones).
  3. Activate Reverse Charging in the notification curtain.

This will allow both devices to be charged at the same time with minimal speed losses.

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

Devices like the Xiaomi Mi 9, Redmi Note 8 Pro or POCO F1 support Quick Charge 4.0 or 18W, but often require additional manipulations to unlock full power.

  • πŸ”§ Firmware update: some older models received support 27W or 30W post-refresh MIUI. Check the relevance of the software in the Settings β†’ The phone. β†’ Updating the system.
  • πŸ”Œ Cable Replacement: Xiaomi’s original 2018–2019 cables are often limited 10W. Buy a Certified Cable USB-C 3.1 with support 5A.
  • πŸ“² Resetting: on some firmware, resetting to factory settings restores the original parameters of the power controller.

For the POCO F1 and Mi 8, there is an informal method of overclocking charging through the Magisk module FastChargeEnabler:

  1. Install Magisk and get root rights.
  2. Download the FastChargeEnabler module from the Magisk repository.
  3. Activate the module and restart the device.

⚠️ Note: Using Magisk voids warranty and may cause system instability. On some devices (e.g. Redmi Note 7), this method causes battery overheating!

7.How to check the actual charging speed

To make sure that fast charging actually works, use one of these apps:

AnnexWhat showsReference
AccuBatteryCharging current (mA), temperature, battery wearGoogle Play
AmpereCurrent, voltage, power (W) in real timeGoogle Play
Battery GuruCharging schedule, time to full chargeGoogle Play

Normal indicators for fast charging:

  • 33W: 6.6V Γ— 5A (~3000-3500 mA).
  • 67W: 10V Γ— 6.7A (~5000–5500 mA).
  • 120W: 20VΓ—6A (~8000–9000 mA).

If your readings are lower by 30% or more, check the cable, power supply or settings as described in Section 4.

FAQ: Frequent questions about fast charging Xiaomi

Can I use charging from another manufacturer (Samsung, Apple, OnePlus)?
Yes, but with reservations: Samsung chargers (e.g., 45W from the Galaxy S22) are compatible with Quick Charge and PD, but may not give maximum power on Xiaomi. Apple (20W) power units work, but are limited to 18W. OnePlus (Warp Charge) is not compatible with Xiaomi technologies - the speed will be like conventional charging. For full power, use PD 3.0 or Quick Charge 4.0+ (e.g., Anker 737 or Baseus 65W).
Why does the phone charge up to 80% and then slow down?
This is the normal behavior of modern smartphones β€” adaptive charging function, which: Prevents battery wear when constantly charging up to 100%. Reduces the risk of overheating in the last stage (most dangerous for Li-ion batteries). To disable the restriction: Go to Settings β†’ Battery β†’ Battery settings. Turn off Optimized Charging or Adaptive Charging. on some models (e.g. Xiaomi) 13T) This menu is hidden - use it ADB-Section 3 teams.
Is fast charging harmful to the battery?
Yes, but not critical. Studies show that: When using fast charging, battery capacity decreases by ~10-15% in 2 years (versus ~5-10% for normal charging). The main damage is caused by heat, not by high current. If the phone does not warm above 40 Β° C, the risk is minimal. Xiaomi uses graphite anodes and cooling systems that reduce wear. Recommendations for extending its life: Avoid charging to 100% (optimally - 80-90%). Do not charge the phone at temperatures below 10 Β° C or above 35 Β° C. Use the original temperature they are optimized.
Can I enable fast charging on Redmi with a MediaTek processor?
Yes, but with nuances. MediaTek devices (like Redmi Note) 12 helio G99) Supports Quick Charge 4+ and PD 3.0, Fast Charging can be called Pump Express or MediaTek Fast Charge.Some models require special firmware to unlock full power (for example, Redmi). 10C limited 18W in the global version, but supports 33W In Chinese, use the forced inclusion ADB-Adb shell settings put global mtk_fast_charge_enabled 1
What if the MIUI update has stopped fast charging?
This is a common problem after major updates (e.g. when switching to HyperOS).Solutions: Reset battery settings: Settings β†’ Annexes β†’ Application management β†’ Battery β†’ Clear the data, roll back to the previous version MIUI Install a custom core (e.g., FrancoKernel) - requires an unlocked bootloader. Contact Xiaomi for support - sometimes the problem is solved by a reset EFUSE (If the problem occurred after upgrading to HyperOS, check the settings in Settings β†’ Battery β†’ Charging modes – there may appear a new Smart Charge switch that limits current.
