How to make Xiaomi phone charge faster: proven methods

Are you tired of waiting for hours for your Xiaomi to gain at least 50% of the charge? Or do you need to urgently recharge your smartphone before you go out, but standard charging takes too long? The problem of slow charging is familiar to many owners of Redmi, POCO and Mi devices - even despite the promises in the characteristics of the "fast" protocols Quick Charge or HyperCharge.

In this article, we’ll look at 10 real-world ways to speed up Xiaomi charging, from basic (check cable) to advanced (processor core settings). All methods have been tested on current models from 2023 to 2026: Redmi Note 12 Pro+, POCO X5 Pro, Mi 13 Ultra and others. And you’ll also learn why sometimes even the original power supply does not give the declared 120W, and how to fix it.

1. Use original charging (or certified)

The first thing to check is the power supply and the cable. Many users save on accessories by buying cheap ones on AliExpress, but this often results in a loss of 30-50% of the charging speed. For example, tests show that a non-original USB-C cable for the Redmi Note 11 can reduce power from 67W to 18W.

How to choose the right adapter:

• 🔌 Power: Must match or exceed the maximum supported by your model. POCO F5 (67W) take the block 67W+, not 33W.
• 🔗 Cable: Original or Certified USB-IF (The package must have a logo. Cheap cables often don't support protocols. PD 3.0 or QC 4.0+.
• 📦 Brand: Best alternatives to the original - Anker, Baseus, Ugreen (look for models marked "GaN" for compactness).

⚠️ Note: If you’re using charging from another device (like a MacBook), make sure it supports the protocol. USB Power Delivery (PD). Xiaomi may limit power to 10–15W.

2. Enable the "Fast Charging" mode in the MIUI settings

Many people don't know, but MIUI has hidden settings that can speed up or slow down charging, and by default, the system often limits power to extend battery life, to remove that limitation:

1. Go to Settings → Battery and Performance → Battery Settings
2. Select Fast Charging (or Optimized Charging on New Models).
3. Activate the switch to always use fast charging.

On some devices (such as the Mi 12T), this item may be called Turbo Mode. If it is not, then your model does not support software acceleration (but you can try the methods in the following sections).

Open "Battery settings" | Find "Fast Charging" |Enable "Always use" |Reboot phone (if no changes apply)

-->

It’s also worth turning off Adaptive Charging (if any) which artificially slows charging down to 80% to extend battery life, but in critical situations it only gets in the way.

3. Turn off the phone while charging (or switch to airplane mode)

One of the most effective ways to speed up charging is to minimize the load on the processor, so when the phone is turned on, it wastes energy on background processes, app updates, and network connectivity, and as a result, some of the power is used to keep the system running instead of charging.

Tests show that:

• 📵 Aircraft mode: speeds up charging on 15–20% (switch off 4G/5G, Wi-Fi, Bluetooth).
• ⏻ Full shutdown: increases up to 25-30%, but not suitable for everyone (do not use the phone).
• 🔄 Reboot before charging: closes unnecessary processes, adds ~10% speed.

⚠️ Warning: If you turn off your phone for accelerated charging, do not use fast charging for longer than 1 to 1.5 hours in a row.This can overheat the battery, especially in hot weather.

4.Controll the temperature of the phone

Overheating is the main enemy of fast charging. At a battery temperature above 40°C, Xiaomi automatically reduces the charging power to avoid damage. For example, the Redmi K60 Pro at 45°C can sag from 120W to 10W.

How to avoid overheating:

• ☀️ Do not charge in the sun or near heat sources (battery, heater).
• 🧊 Remove the case – especially if it is thick or made of in breathless materials (silicone).
• 💨 Use cooling: You can point a fan at your phone or put it on a metal surface (for example, a radiator from a laptop).
• 🎮 Do not play while charging – games load the processor, which raises the temperature.

💡

If your Xiaomi is warming up a lot even without a load, check the battery status in the engineering menu: enter the phone application code ##4636##, then select Battery Information. Temperatures above 45°C at rest are an excuse to visit the service.

5. Update MIUI firmware to the latest version

Charging performance is not only hardware-dependent, but software-based optimization, and newer versions of MIUI often fix power management bugs, such as the HyperCharge protocol for the Mi 11 Ultra, which has been updated to deliver a 12 percent increase in speed.

How to update:

1. Open Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, download and install it (preferably via Wi-Fi).

If the update doesn’t help or doesn’t, you can try resetting your energy saving settings:

1. Go to Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select Reset Settings.
3. Select Reset Battery Settings.

💡

After updating MIUI, reset the system cache: turn off the phone, then press the Power button + Volume up until the logo appears. From the recovery menu, select Wipe cache partition. This will help avoid conflicts with the new charging algorithms.

6. Optimize background processes

Even if you don’t run games or heavy apps, MIUI can spend energy on background tasks such as syncing accounts, weather updates, checking email, etc. To free up power for charging:

Step 1. Turn off autosynchronization:

• Go to Settings → Accounts and Synchronization.
• Turn off automatic sync for unnecessary accounts (Google, Mi Account, etc.).

Step 2: Limit the activity of the applications:

• Open Settings → Applications → Application Management.
• Select an app (like Facebook or TikTok) and click Background Limitation.
• Set a limit on No Limits or Saving Charge.

Step 3: Enable Charge Saving (paradoxically, but helps):

In this mode, MIUI aggressively closes the background processes, which reduces the load on the processor, so more power goes to the charger.

1. Go to Settings → Battery and Performance → Battery Mode.
2. Choose Charge Saving or Supereconomic Mode.

7. Check the status of the battery and USB-C port

If all of the above methods fail, the problem may be the physical wear and tear of the battery or connector, and over time, the battery capacity decreases and the USB-C contacts become oxidized or contaminated, which impairs the power transfer.

How to check the battery:

• 📊 Use the AccuBattery app (available on Google Play) to show the actual battery capacity and charging/discharge rate.
• 🔋 If the capacity fell below 80% of the factory battery, it is time to change (at the Xiaomi service center it is worth it). ~2 500–4 000 ₽).

How to clean the USB-C port:

• 🪥 Carefully remove dust and debris with a wooden toothpick (do not use metal objects!).
• 💧 Wipe the contacts with an alcohol napkin (without bigotry, so as not to damage the coating).
• 🔌 Check if the connector is wobbling - if so, then a replacement (cost) is required. ~1 500–3 000 ₽).

⚠️ Warning: If the phone shows a message when charging, "Charging suspended. Humidity in the connector," do not ignore it! This can lead to a short circuit. Let the phone dry for 1-2 hours or use a dryer (cold air!).

8.Alternative methods: from engineering menu to Power Bank

If the standard methods don't work, you can try advanced techniques, which require caution, but sometimes help you get the most out of charging.

Method 1. Engineering menu (only for power users!)

In Xiaomi's engineering menu, you can manually adjust charging options, like increasing the current or turning off temperature restrictions. It's risky -- wrong settings can damage the battery!

How to open it:

1. Enter the phone app code ##4636##.
2. Go to Battery Information.
3. Pay attention to the parameters of battery health and temperature.

Method 2: Use Power Bank with fast charging support

If the socket is not at hand, but you need to urgently charge, take an external battery with support for PD 3.0 or QC 4.0+. For example, Xiaomi Power Bank 3 20000mAh gives up to 30W, which is enough for fast recharging Redmi or POCO.

Method 3: Charging from a laptop or PC (if there is no power supply)

Modern laptops (especially those with USB-C Thunderbolt ports) can deliver up to 15 to 20W. This is slower than an outlet, but better than nothing.

• 💻 Use the port. USB-C (not USB-A).
• 🔌 Connect your phone directly, without hubs or extension cords.
• 🔋 Turn off your laptop or put it in sleep mode, so it will give more power.
