How to enable fast charging on Xiaomi Redmi 10: all ways and settings

What to Know About Fast Charging on Redmi 10

Xiaomi Redmi 10 is a popular budget smartphone that supports Quick Charge 3.0, but it doesn’t always work out of the box. Many users find that the device charges slowly, even though it comes with an 18W or 22.5W adapter.

In this article, we’ll look at how to check for fast charging support on your Redmi 10, enable it through hidden MIUI settings, and what accessories you’ll need for top speed. It’s important to understand that even when set up correctly, the charging speed depends on the battery temperature, the cable condition, and the firmware version.

If you use a non-original charger or low-quality cable, your smartphone can automatically limit power, and we'll tell you how to avoid that and what parameters affect the process.

Checking support for fast charging on Redmi 10

Before you try to enable Quick Charge, make sure your Redmi 10 supports this technology at all. Not all smartphone modifications come with the necessary electronics, especially if the device was bought in unofficial stores.

This can be done in two ways:

• 🔍 Through settings MIUI: Go to Settings. → The phone. → All the features. Find the line "Fast charging." If it's not, your model doesn't support the technology.
• 📦 The original Redmi 10 packaging must be marked «18W Fast Charging" or «22.5W Fast Charging: If it says only «10W», So there's no fast charging.

Also worth checking is the firmware version. Old MIUI builds (below 12.5) may have power-limited bugs. Update through Settings → Software Update if a new version is available.

What accessories are needed for fast charging

Even if Redmi 10 supports Quick Charge, it requires compatible accessories to work, and using an inappropriate charger or cable can not only slow down charging, but also damage the battery.

Here's what you're gonna need:

• ⚡ Charging unit: original from Xiaomi on 18 Watt/22.5 W or third-party with Quick Charge support 3.0/4.0, Power Delivery (PD). Budget options will fit blocks from Baseus or Anker.
• 🔌 Cable: USB Type-C with high current support (preferably original or certified) USB-IF). Cheap cables often limit power to 10 watts.
• 🔋 Battery condition: If the battery is worn out (capacity below 80%), the smartphone can automatically reduce the charging speed for safety.

Note that some Redmi 10s (especially India versions or global versions) may require special firmware to unlock full power. If you use custom software (like Pixel Experience), check the kernel settings.

💡

To check the actual charging power, install the AccuBattery (Play Market) app, which will show the current current and voltage in real time.

How to enable fast charging through MIUI settings

In most cases, Quick Charge on Redmi 10 is activated automatically when a compatible charger is connected, but sometimes manual configuration is required.

1. Connect your smartphone to a charger with Quick Charge 3.0 support.
2. Go to Settings → Battery and Performance.
3. Tap on Battery Settings → Fast charging.
4. Activate the switch Enable fast charging (if any).

If the "Fast Charge" item is not on the menu, then your firmware is hiding this option, in which case the hidden engineering menu will help:

1. Open the phone app and enter the combination: ##4636##
2. Go to the Battery Information tab.
3. Check the AC powered line – if it says USB instead of Fast, then charging is in normal mode.

Why fast charging doesn't work: common problems

If you’ve completed all the steps, but the Redmi 10 is still charging slowly, the reasons may be as follows:

Important: on some versions of Redmi 10 (e.g. Redmi 10 Prime for India), fast charging is disabled by default due to local regulatory requirements, in which case only the firmware of the global version of MIUI will help.

How to speed up charging without harming the battery

Even if Quick Charge works, you can further optimize the process.

• ❄️ Charge at room temperature: ideal range of 10–30°C. In the heat (>35°C) the controller reduces power.
• 📵 Turn off unnecessary features: Wi-Fi, Bluetooth, mobile data and background apps reduce heat.
• 🔄 Use Air Mode: This reduces the load on the processor and speeds up charging by 10-15%.
• 🔋 Do not bring to 100%: for battery durability it is better to charge up to 80-90% and not leave on charging overnight.

If you use fast charging often, calibrate your battery every 3 months:

1. Discharge the smartphone before automatically turning off.
2. Charge to 100% without interruptions (use the original unit).
3. Turn off and turn on the device, then charge back to 100%.

💡

Regular battery calibration helps to reset controller errors and restore an accurate charge level score.

Alternative ways to include Quick Charge

If standard methods don't work, you can try alternative solutions, which require more effort, but sometimes help unlock hidden functions.

Method 1: ADB-Teams (for experienced users):

1. Turn on Developer Mode (7 times tap the MIUI version in your phone settings).
2. Activate USB Debugging in Settings → Additional → For developers.
3. Connect your smartphone to your PC and execute the command: adb shell settings put global fast_charge_forced_enable 1
4. Reset the device.

Method 2: using a custom core (for hardened devices only):

• Install a kernel with Fast Charge support (e.g. FrancoKernel or Perseus).
• In a kernel management app (like Kernel Adiutor), find the Fast Charge option and activate it.

⚠️ Attention: use ADB-commands or custom cores can lead to loss of warranty or unstable operation of the smartphone!
