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.
Itβs important to understand that even Xiaomiβs 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:
- π Check out the features on the official website mi.com (select the region "Global" or "Russia").
- π± Enter the model in the search engine with the request "model" + fast charging specβ (e.g. Xiaomi) 13T Pro fast charging spec).
- π 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.
| Xiaomi model | Max. Charging power. | Technology | Do you need an original cable? |
|---|---|---|---|
| Xiaomi 14 / 14 Pro | 90W / 120W | HyperCharge | Yeah (with a chip) |
| Redmi K70 / K70 Pro | 120W | Quick Charge 5 + PD 3.0 | Recommended |
| POCO F6 Pro | 120W | HyperCharge | Yes. |
| Redmi Note 13 Pro+ | 120W | Quick Charge 4+ | No (but speed is lower) |
| Xiaomi 13 Lite | 67W | Power Delivery 3.0 | No. |
If your model doesnβt make it to the table, check it with GSMArena. Note that some budget devices (like the Redmi A2 or POCO C50) only support 18W, in which case βfast chargingβ will be limited to the Quick Charge 2.0 standard.
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:
- Open the Settings. β Battery.
- Slap the icon. βοΈ ("Battery settings") in upper right corner.
- Select Charging Mode (on some firmwares β Charging Optimization).
- Activate the Fast Charging or Accelerated Charging switch.
- 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 ModeUse 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:
- β‘ Power supply: should support PD Quick Charge 3.0+ (power 30W).
- π Cable: Original or Certified USB-C to USB-C high-current.
- π± Temperature: If the battery is overheated (>40Β°C) or supercooled (<10Β°C), charging is automatically limited.
π‘
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:
- Open the Phone app and type ##4636##.
- Go to the section Information about the battery.
- Tap it on. AC charge current and set a maximum value (e.g., 5,000 mA for a 120W-charging).
- Save the settings and restart the device.
What happens if you set the current too high?
Method 2: ADB-teams (no root rights)
If the engineering menu is not available, use ADB:
- Install Platform Tools on your PC.
- Turn on USB debugging in the developer settings (Settings β About Phone β MIUI version β tap 7 times).
- Connect your phone to your PC and execute the command: adb shell settings put global fast_charge_forced_enable 1
- For models with HyperCharge add: adb shell settings put global hyper_charge_enabled 1
β οΈ 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 cause | Decision |
|---|---|---|
| Charging goes to 10W instead of 33W+ | Unoriginal cable/power supply unit | Use a complete RAM or a certified RAM (e.g. Anker 735) |
| The phone is warming up and slowing down. | Background processes or high ambient temperature | Close the applications, reduce the brightness of the screen, remove the case |
| Fast charging only works up to 80% | The option "Optimized charging" is enabled | Turn off the settings β Battery β Battery settings |
| The RMS is not defined as βrapidβ | 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:
- Go to Settings β Applications β Application Management.
- Find the battery and clear the cache.
- Turn off the phone from charging, wait 1 minute and plug it back in.
π‘
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 doesnβt support fast charging or you want to further optimize the process, use these tips:
- β‘ Aircraft mode: Disables all radio modules (4G, Wi-Fi, Bluetooth, reducing charging time by 15-20%.
- π Background Disconnect: Close all applications through Recent or use Memory Optimization in Settings.
- π‘οΈ Cooling: Put your phone on a metal surface or use a cooling stand (e.g. Baseus Cooler).
- π 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:
- Connect your phone to a 67W+ wired memory.
- Put another Qi-enabled device on the back (e.g., Xiaomi Buds 4 Pro headphones).
- 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.
- π§ 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.
- π Cable Replacement: Xiaomiβs original 2018β2019 cables are often limited 10W. Buy a Certified Cable USB-C 3.1 with support 5A.
- π² 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:
- Install Magisk and get root rights.
- Download the FastChargeEnabler module from the Magisk repository.
- Activate the module and restart the device.
β οΈ 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:
| Annex | What shows | Reference |
|---|---|---|
| AccuBattery | Charging current (mA), temperature, battery wear | Google Play |
| Ampere | Current, voltage, power (W) in real time | Google Play |
| Battery Guru | Charging schedule, time to full charge | Google Play |
Normal indicators for fast charging:
- 33W: 6.6V Γ 5A (~3000-3500 mA).
- 67W: 10V Γ 6.7A (~5000β5500 mA).
- 120W: 20VΓ6A (~8000β9000 mA).
If your readings are lower by 30% or more, check the cable, power supply or settings as described in Section 4.
