In this article, we will understand how to check the support for fast charging on your model, activate it through settings. MIUI, We will also address typical problems, from unoriginal cables to software constraints. 13/14, Mix Fold and budget lines (Redmi Note, POCO).

1.What fast charging technologies does your Xiaomi support?

Before you enable accelerated charging, make sure your smartphone supports it. Xiaomi uses several standards, and their capabilities depend on the model:

• 🔋 Quick Charge 3.0/4+ — basic technology (up to) 18W), It's compatible with most adapters. 9/10, POCO M3/M4.
• ⚡ Super Charge – a brand standard (33W–67W). Used in Mi. 10/11, Redmi K40/50, POCO F3/4.
• ⚡⚡ HyperCharge is the fastest charging system (120W–200W). Available on flagships: Xiaomi 12 Pro, 13 Ultra, Mix 4.
• 🔄 Reverse Charge – Reverse wireless charging (up to) 10W), I'm on the Mi 11 Ultra, 12S Ultra.

To find out the maximum charging power of your model, check the specifications on the official Xiaomi website or in the documents to the device. For example, the Redmi Note 12 Pro+ supports 120W HyperCharge, but only with the original adapter.

⚠️ Note: If you use an adapter that is higher than the phone supports (e.g, 120W For the Redmi Note 10, charging will be limited to maximum power. There is no risk of damage, but there is also a speed gain.

2. How to enable fast charging in MIUI settings

On most Xiaomi smartphones, fast charging is activated automatically when you connect a compatible adapter, but in some cases it needs to be manually enabled:

1. Open the Settings. → Battery.
2. Select Charging (on some models – Charging settings).
3. Activate the Fast Charge switch (or Super Charge/HyperCharge, depending on the model).
4. If you do not have an option, check the section Additional settings → Fast charging.

Some devices (such as the Xiaomi 12T or Redmi K50) have a separate setting for overnight charging, which may limit speed.

Settings → Battery → Night charging → Disconnect

Use the original cable and adapter|Check the version. MIUI (update if necessary)|Turn off the power saving mode|Make sure your phone temperature is below 40°C|Check the settings in the "Battery" section"-->

If the Quick Charging option is inactive or absent, the reason may be:

• 🔌 Unoriginal adapter or cable (see the section about accessories).
• 📱 Refreshing the old slate (refresh) MIUI through settings → The phone. → Updating the system).
• 🔋 Power saving mode enabled (Settings) → Battery → Energy saving regime).
• 🌡️ Overheating of the phone (charging is automatically limited at temperatures above 40)°C).

💡

On models with HyperCharge (120W+), fast charging can be turned off by default to protect the battery.

3. Why fast charging doesn't work: top-5 cause

If Xiaomi’s smartphone charges slowly despite the right settings, check out these common problems:

1. Non-original accessories

Using uncertified cables or adapters can reduce charging speeds to 5W-10W, even if they support high power. Xiaomi's original accessories have an authentication chip that confirms compatibility with Super Charge/HyperCharge.

2.A damaged USB-C port

Oxidation of the contacts or mechanical damage to the port leads to poor contact. Check the port for debris and clean it with a plastic (not metal!) toothpick if necessary.

3.Outdated firmware

Older versions of MIUI (below 12.5) may not have drivers for the new charging standards.

Settings → About phone → System update → Check for updates

4. Power saving mode on

Super Power Saving or Ultra Power Saving modes limit charging to 10W. Turn them off in Settings → Battery.

5. overheating of the phone or adapter

At temperatures above 40°C, Xiaomi automatically reduces the charging power.Let the device cool down or remove the case.

💡

If the phone is warming up while charging, try using a lower power adapter (like a 33W instead of a 67W) to reduce battery load and prolong battery life.

⚠️ Note: On some models (Xiaomi) 11T, 12 Pro after update MIUI 14 may reset Fast Charging setting. Check it after each update.

4.How to check the actual charging speed

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

• 📊 AccuBattery (shows current and power in real time).
• 🔋 Ampere (displays current strength during charging/discharge).
• 📱 Built-in monitor MIUI: Settings → Battery → Condition (on some models).

Normal indicators for different technologies:

• Quick Charge 3.0: 12W–18W (current 1.5A–2.5A).
• Super Charge 33W: 25W–33W (current 3A–5A)
• HyperCharge 120W: 80W-120W (current 6A-10A).

If the app is below the expected power (e.g. 5W instead of 33W), then fast charging is not activated. Go back to the settings section or check the accessories.

5.What cables and adapters are suitable for fast charging Xiaomi

For the full operation of Super Charge and HyperCharge, you need original accessories or certified analogues.

Power adapters

The power of the adapter must match or exceed the maximum charging power of the phone.

• The Redmi Note 11 Pro+ (120W) requires a 120W adapter (included).
• For the POCO X5 Pro (67W), a 67W or 100W adapter is suitable.
• The Redmi 10 (18W) will have an 18W-33W adapter.

Cables.

Use USB-C 2.0/3.0 cables and a current of at least 3A. Xiaomi's original cables have an orange or red swipe (for Super Charge). Cheap cables often limit current to 2A, which reduces charging speed.

⚠️ Note: Adapters from other brands (such as Samsung or OnePlus) may not support HyperCharge, even if their power matches. Use only adapters with the Xiaomi logo or certified ones. USB-IF.

6. Fast charging on older Xiaomi models (Redmi) 4/5, Mi A1/A2)

Xiaomi 2016-2018 smartphones (Redmi 4/5, Mi A1, Mi 6) support Quick Charge 3.0, but it requires:

1. Use an adapter with QC 3.0 support (e.g. Xiaomi 18W or Anker PowerPort).
2. Enable the option in the engineering menu (see below).
3. Update the firmware to the latest version of MIUI (or Android One for Mi A1/A2).

To activate Quick Charge 3.0 on older models:

1. Dial in the phone app: ##4636##


2. Select "Battery Information".




3. Check the line "Charging Technology." If it says "Standard", then QC 3.0 is not activated.




4. Use the Quick Charge Checker app to force inclusion (root rights required).

On the Redmi Note 4/5, fast charging may not work with non-original adapters due to firmware limitations, in which case flashing to custom software (such as LineageOS) will help, but this will void the warranty.

💡

On the Mi A1/A2 (Android One), fast charging is enabled automatically when you connect a compatible adapter. If it doesn't work, try resetting through Settings → System → Reset.

7. How to extend the battery life when using fast charging

Super Charge and HyperCharge technology speed up charging, but can shorten battery life when used continuously.

• 🔋 Avoid charging to 100%. Optimal range is 20%-80%.
• ⚡ Don't use fast charging at night. After 80%, turn off the adapter or switch to standard charging.
• 🌡️ Do not charge your phone in extreme temperatures (below 0)°C or higher than 40°C).
• 📵 Turn off Wi-Fi, mobile data and Bluetooth while charging to reduce heat.
• 🔄 Once a month, complete a full discharge/charging cycle (0%–100%) to calibrate the battery.

On models with MIUI 12.5+, there is an integrated Optimized Charging feature that automatically limits the charge to 80% and brings it up to 100% just before the intended shutdown.

Settings → Battery → Settings → Optimized charging

If you use HyperCharge (120W+), try not to charge your phone faster than 50% in 15 minutes, which puts a high load on the battery. 33W-67W is enough for everyday use.
