How to enable fast charging on Xiaomi Redmi Note 10: full instructions with nuances

Why fast charging on the Redmi Note 10 might not work out of the box

The Xiaomi Redmi Note 10 supports 33W fast charging, but many users find the device charging slowly as if the function is off. It's not because of hardware limitations, but because of MIUI settings and charging protocols, because by default the system can limit current to extend battery life, especially if a non-original charger is used.

In this article, we’ll look at all the ways to activate fast charging on the Redmi Note 10 (including the Pro, Pro Max, and 5G versions), explain why a smartphone sometimes “can’t see” a 33-watt adapter, and give a checklist to diagnose problems.

Important: The Redmi Note 10 uses Quick Charge 3.0 and MI Fast Charge, but not only does it require the original adapter to work properly, but it also requires the right firmware. If your phone charges for longer than 1.5 hours from 0 to 100%, that’s a good reason to check the settings.

1. Checking for fast charging support: Is your Redmi Note 10 compatible

Before you start charging fast, make sure your Redmi Note 10 model supports it. Not all versions are equipped with 33-watt technology:

• 🔋 Redmi Note 10 (mojito) – 22.5 watts (Quick Charge 3.0)
• 🔋 Redmi Note 10 Pro (sweet) - 33 watts (MI Fast Charge 3.0)
• 🔋 Redmi Note 10 Pro Max (camellian) – 33 watts + 9W wireless charging
• 🔋 Redmi Note 10 5G (camellia - 18 watts (Quick Charge 3.0)

To determine the model exactly, go to Settings → About Phone → Model. If your smartphone only supports 18 or 22.5 watts, then 33 watt charging is physically impossible – the most you can do is optimize the current process.

Also check the firmware version: in older MIUI builds (below 12.5), fast charging may not work smoothly. Update the system through Settings → Software Update.

2. How to enable fast charging in MIUI settings

MIUI has hidden options that can limit charging power.

1. Open Settings → Battery and Performance.
2. Select Battery Settings → Charging Mode.
3. Activate the "Fast Charging" switch (if any).
4. In some firmwares, you need to additionally turn on “Smart Charging” and turn off “Restriction of Charging” (if it is active).

If you don't have a quick charge, your firmware doesn't support it, in which case try an alternative method through the engineering menu (described below).

Check the phone model (33 watts only for Pro/Pro Max)

Update MIUI to the latest version

Use the original Xiaomi cable and adapter

Disable "Smart Charging" in the Battery Settings-->

Attention! On some custom firmware (e.g. Pixel Experience or LineageOS), fast charging may not work due to the lack of Qualcomm Quick Charge drivers. MIUI.

3. Engineering menu: hidden charging settings

If the standard settings don’t work, you can activate fast charging via the engineering menu (#4636###), which works on most versions of MIUI, but you need to be careful:

1. Open the Phone app and enter the combination ##4636##.
2. Go to the Battery Information tab.
3. Check the AC Charging line – if the value is less than 9V/2A, then fast charging is turned off.
4. Go back to the main menu of engineering settings and select Hardware Testing → Charging.
5. Activate the Fast Charge option (if available).

Critical: on some firmware, after activating fast charging through the engineering menu, the phone may start to warm up stronger than usual. If the temperature exceeds 45 ° C, turn off the function and use the original adapter.

4.Selecting a charger: why the original adapter is important

Even if you’ve enabled fast charging in the settings, the Redmi Note 10 can ignore it because of an incompatible adapter or cable. Xiaomi uses the proprietary MI Fast Charge protocol, which doesn’t always work correctly with other brands’ charging.

For full 33-watt charging, use only the original Xiaomi adapter labeled MDY-11-ED or MDY-12-ED. The cable should support a current of at least 3A (usually USB-C → USB-C).

⚠️ Caution: Cheap cables without shielding can overheat at high currents, causing port damage USB Use certified accessories (such as Anker PowerLine or UGREEN).

5. Software limitations: why MIUI blocks fast charging

MIUI has built-in algorithms that can artificially restrict charging in the following cases:

• 🔥 Overheating of the phone (over 40)°C) - the system automatically reduces current.
• 🔋 Battery wear (capacity below 80%) - "sparing mode" is included".
• 📱 Background processes (games, video shooting) – charging slows down for stability.
• 🔌 Unoriginal adapter — MIUI You may not trust the “unknown” chargers.

To circumvent these restrictions:

1. Reboot your phone before charging (this will reset the background processes).
2. Turn off the settings → Battery → Smart charging.
3. Use air mode while charging (reduces heating).
4. Check the battery status through the AccuBattery app (if wear is >30%, charging will be limited).

Note: The Redmi Note 10 Pro Max has an optional Settings → Battery → Battery Status, where you can reset your wear statistics (but this won’t restore real capacity!).

💡

If the phone gets too hot when charging, remove the case and put it on a cooling stand. Temperatures above 45°C can damage the battery, even if charging is fast.

6. Alternative methods of accelerating charging

If the standard methods don’t help, try these advanced techniques:

Method 1: Disabling MIUI Optimization

MIUI has a hidden feature called Background Limitation, which can interfere with charging, to turn it off:

1. Turn on Developer Mode (7 times click on Version) MIUI" phone-setting).
2. Go to Settings → Additional → For developers.
3. Find the "Background Limitation" option and turn it off.
4. Also turn off MIUI Optimization and Adaptive Brightness.

Method 2: Use of the ADB-team

For power users, there is a way to force fast charging through ADB:

adb shell settings put global fast_charge_forced_enable 1

Once you've done this, restart your phone. To get it back, use:

adb shell settings put global fast_charge_forced_enable 0

⚠️ Attention: Misuse of the right ADB It can cause a reset or damage to the firmware. If you're not sure, don't experiment!

Method 3: Custom core firmware

XDA Developers forums have modified cores (such as FrancoKernel) that unlock full charging power.

• Unlocked bootloader (bootloader).
• Installed by TWRP or OrangeFox.
• Firmware experience.

Without this knowledge, it is better not to take risks – the wrong firmware can turn a phone into a brick.

💡

If you’re not ready for the risks with ADB or custom firmware, it’s best to limit yourself to buying the original Xiaomi adapter and optimizing your MIUI settings.

7.Diagnostics of problems: why fast charging doesn't work

If after all the manipulations the phone still charges slowly, go through this checklist:

If none of the methods worked, check the status of the battery:

1. Install the AccuBattery app.
2. Check out the battery health setting.
3. If the value is below 70%, the battery is worn out and needs to be replaced.

Tip: Redmi Note 10 Pro/Pro Max can replace the battery itself - it is attached to double-sided tape, the main thing is to use the original battery with the article MB01 or MB02.
