How to charge your Xiaomi phone fast: 0% to 100% in an hour

Are you in a hurry, and Xiaomi's phone is running out of power? Everyone knows the situation: you need to get in touch, use the navigator or pay for a purchase, but the battery is at zero. Fortunately, the brand's smartphones support fast charging technology, and MIUI has hidden features to speed up the process. But even with them, many users make mistakes that cause charging to last for hours.

In this article, 7 proven ways to charge the Redmi Note 12, POCO X5, Mi 13 and other Xiaomi models as quickly as possible without risking battery health.

• 🔌 What chargers do you have? +50% in 15 minutes (compatible model list)
• ⚡ Hidden settings MIUI, charge-up 20-30%
• ❄️ Why cooling your phone increases charging speed by 1.5 times
• ⚠️ 3 common mistakes that make Xiaomi charge 2 times slower

All methods are tested on current MIUI 14/15 firmware and are suitable for devices that support Fast Charging, Turbo Charge and HyperCharge. If your model is older than 2020, please see the section on hardware limitations.

1.Use the original charging with HyperCharge support

The first rule of fast charging is power supply. Xiaomi smartphones of the latest generations support technology:

• 🔋 Fast Charge 3.0 (18–33 W) – basic version for budget models (Redmi) 10A, POCO M5)
• ⚡ Turbo Charge 4.0/5.0 (33–67 W - medium segment (Redmi Note) 11 Pro, Mi 11 Lite)
• ⚡⚡ HyperCharge (120–210 W) – flagships (Xiaomi 13 Ultra, Redmi Note 12 Pro)+)

If you connect the Xiaomi 12T Pro (120 watts) to a Redmi 9A (10 watts) charger, the phone will charge 10-12 times slower.

Critical error: 70% of users use non-original cables that limit power to 10-15 watts, even if the power supply supports 120 watts. Check the labeling on the cable - it must be certified for 5A/240W (for example, USB-C to USB-C with an E-Marker chip).

⚠️ Note: Chargers from Samsung or Apple (even with the same power) are often not compatible with Xiaomi due to different fast charging protocols.Use only Qualcomm Quick Charge 4-enabled units+ or USB PD 3.0.

2. Enable Ultra-Fast Charging in the MIUI settings

Even with a powerful power supply, Xiaomi can artificially limit the charging speed to remove the restrictions:

1. Go to Settings → Battery and Performance → Charging.
2. Activate the Ultra-Fast Charging switch (on some models, Turbo charging).
3. If you do not have an option, check the section Additional settings → Charging optimization.

Phones with HyperCharge (120+W) also have Boost charging, which temporarily disables background processes.

Settings → Special features → Functions for developers → Debugging by USB (enable) → Return to Charging and select Boost mode

Disable Wi-Fi and Mobile Data

Close all applications in multitasking

Remove the cover (overheating reduces speed)

Use the original cable

-->

⚠️ Warning: Boost charging increases battery wear by 10 to 15 percent when used regularly.

3.Cold the phone before charging

The battery temperature directly affects the charging speed. When heated above 40°C, the Xiaomi controller automatically reduces the power to 5-10 W. The optimal range for fast charging is 15-35°C.

How to cool your phone before connecting to the network:

• ❄️ Put the device in the shade for 10-15 minutes (if it was in the sun).
• 🧊 Use a cooling stand with a fan (e.g. Baseus Cooler Pad).
• 📱 Disable all resource-intensive tasks: games, video editing, AR-applications.
• 🔄 If your phone overheats while charging, turn it off for 5 minutes – it will reset the temperature limit.

💡

If you have a POCO F4 GT or Black Shark 5, activate Game Cooling in the performance settings, which reduces the CPU temperature by 5-8°C by limiting the clock speed.

4. Turn off optimized charging

The MIUI’s Optimized Charging (or Adaptive Charging) function deliberately slows the process after 80% to extend battery life, and in emergency cases, it must be turned off:

1. Open Settings → Battery and Performance → Charging.
2. Find the option “Optimized charging” and deactivate it.
3. On some models (Mi 11, Mi 12) the path is different: Settings → Battery → Battery settings → Adaptive charging.

If the option is not on the menu, try resetting the battery settings:

Settings → Applications → Application Management → Three dots (menu) → Reset application settings → Select “Battery”

⚠️ Warning: After switching off optimized charging, don’t leave your phone on overnight charging – this reduces battery life by 20–30% per year.

5. Use aviation mode (flight mode)

Background processes are the main thief of charging speeds, and even in standby mode, Xiaomi spends up to 5-10% of its power on:

• 📶 Searching the net (4G/5G)
• 📡 Wi-Fi and Bluetooth scanning
• 📍 Background location (GPS)
• 🔔 Push notifications from applications

The solution is flight mode. It shuts down all radios, reducing charging time by 25 to 40 percent.

• 🛫 Quick way: swipe down from the top edge of the screen → tap on the icon "Aircraft».
• ⚙️ Alternative: Settings → Connections and sharing → Flight mode.

Yeah, always.

Only in emergency cases.

No, I haven't.

I don't know what it is.

-->

Important: If you need to stay connected, at least turn off:

• 🔍 Device search (Settings) → Bluetooth → Visibility)
• 📍 Exact location (Settings) → Confidentiality → Permits → geodata)
• 🔄 Auto-Update (Play Market) → Settings → Auto-update)

6. Charge the phone in the off state

When Xiaomi is turned off, it consumes a minimum power of only 0.1-0.5 watts (versus 2-5 watts in standby mode).

• ⚡ Speed up charging by 30-50% (for example, from 1 hour to 40 minutes).
• 🔋 Reduce battery heating by 5-10°C.
• 🛡️ Reduce battery wear (no discharge cycle during charging).

How to properly charge the phone off:

1. Connect the original charger.
2. Hold the power button for 10 seconds to turn off the device completely.
3. Wait for the charging icon to appear on the screen (usually in 5-10 seconds).
4. Do not turn on the phone until the charge reaches at least 30-40%.

💡

Charging a phone that is turned off is the most effective method for older models (Redmi 8, Mi A3), where there is no HyperCharge support.

⚠️ Note: On some models (POCO X3, Redmi Note 10) when turned off, the warning “Charge suspended” is displayed, which means that the phone is discharged to 0% and requires 5-10 minutes of recharging before turning on.

7. Alternative methods for older models

If your Xiaomi Released is before 2020 (Redmi 7, Mi 9 SE, POCO F1), it doesn’t support modern fast charging protocols.

Method 1: Use Power Delivery (PD) Charging

Even if the phone doesn't support HyperCharge, it's compatible with USB Power Delivery (up to 18-27 watts).

• 🔌 Anker PowerPort III Nano (20 watts, USB-C)
• 🔌 Baseus 65W GaN (supports) PD 3.0)
• 🔌 Charging from MacBook Pro (29W, USB-C)

Method 2: Turn on Developer Mode and increase the current limit

For experienced users:

1. Activate Developer Mode: Settings → About Phone → MIUI version (shap 7 times).
2. Back to Settings → Additionally. → For developers.
3. Find the option “Charging Current Limitation” and set the value “Disconnected”.
4. Reboot the phone.

Method 3: Replace the battery with a fast-charging model

If your Redmi Note 5 initially only supported 10W but you want 18-33W, you can install a battery from the Redmi Note 7 (BM47 or DM43 models).
