Tired of waiting for hours for your Xiaomi to charge to 100%? Even with fast charging support, real speeds are often below the stated speed. The reason lies not only in the power of the adapter, but also in the hidden limitations of MIUI, quality of accessories and even ambient temperature. In this article, we will discuss 10 proven ways to speed up charging on any Xiaomi, Redmi or POCO device – from budget models to flagships.
It's important to understand that the manufacturer specifically limits the charging speed to the last 20-30% to save battery life. But if you need to urgently restore charge, these restrictions can be circumvented by legal methods. We tested all the methods on models from Redmi Note 12 to Xiaomi 14 Ultra — the results are in the table below. And if you are not sure which adapter is right for your smartphone, use our interactive compatibility guide.
1. Use an original or certified adapter
The first thing that slows charging is the wrong power supply. Even if your Xiaomi supports 120W HyperCharge, a cheap 18W adapter won't make more than 10W. Here's how to pick the right one:
- 🔌 Models with 33W/67W/120W (for example, Xiaomi 13T Pro, Redmi K60): Use only the original adapter from the kit. Third-party units often do not activate full power.
- 🔋 Budget smartphones (Redmi Note series, POCO M: Any adapter with Quick Charge support is suitable 3.0/4.0 Power Delivery (e.g. from Anker or Baseus).
- ⚡ The general rule is that the power of the adapter should be equal to or higher than the maximum supported by the smartphone. POCO F5 (67W) fitting 67W or 120W, not vice versa.
Check the current charging power through the application AccuBattery (Charging section). If the value is below 50% of the stated maximum, there is a problem in the adapter or cable.
📊 What Adapter Are You Using to Charge Xiaomi?
Original from the kit
Third-party (Anker/Baseus, etc.)
Unnamed Chinese
Charging from another device (MacBook/iPad, etc.)
⚠️ Note: Qualcomm Quick Charge adapters and USB Power Delivery is compatible, but can give different speeds. For example, Redmi Note 11 Pro+ s QC 3.0 charges 30% slower than with your family MI Fast Charge.
2. Replace the cable: why USB-C ≠ USB-C
Even with the right adapter, the cable can be a bottleneck, cheap wires often don't support high currents, or have thin veins that overheat.
- 🔗 Certification: Look for marking USB-IF Certified or USB 2.1 (for 60W+). Uncertified cables can limit power to 10-15W.
- 🔍 The thickness of the lived: The optimal option is cables with residential 20AWG (upstream 5A). For example, Xiaomi 100W Fast Charge Cable or UGREEN 140W.
- 🛡️ Screening: Aluminum Foil Shield cables are less susceptible to interference and overheating.
You can check the cable by plugging your smartphone into the adapter and touching the connector in 10 minutes. If it's hot (over 40°C), the cable can't handle the load. Also note the length: cables longer than 1.5 meters lose up to 20% of power.

3. Enable the "Fast Charging" mode in MIUI
By default, MIUI limits the charging speed to protect the battery, but in the settings, you can force the maximum power to be activated.
- Go to Settings. → Battery.
- Put it on the icon. ⚡ in the upper right corner (or select Charging Settings).
- Activate the Fast Charging switch (on some models – Accelerated Charging or Turbo Charging).
- For flagships (Xiaomi 13/14, Redmi K50/K60) turn on HyperCharge.
Some firmware (MIUI 14+) have the option hidden to unlock it:
adb shell settings put global fast_charge_forced 1
This command is forced to enable fast charging even if the system has turned it off.
What if the “Fast Charging” option is not on the menu?
In some models (for example, POCO X3 NFC) The manufacturer removed this setting from the interface: 1. Check the version. MIUI In Settings → Update the firmware to the latest stable version. 2. Install an alternative kernel (requires unlocking the bootloader) or use ADB-top-down. 3. On budget models (Redmi) 9A, POCO M3) fast charging may not be supported hardware, even if the characteristics are specified 18W. 4. Turn off background processes and optimize consumption if the smartphone is actively using CPU/GPU During charging (for example, for synchronization or updates), the charge recovery rate drops to the 30-50%. Here's how to fix it: 🚫 Aircraft mode: Disables all radio modules (4G/5G, Wi-Fi, Bluetooth, reducing power consumption. Charging will accelerate by 15-20%. ❄️ Background activity restriction: Go to Settings → Annexes → Application management → Autostart and disable Autostart for unnecessary programs. 🔄 Forced Stop: In the same menu, select Battery → Battery optimization and set for all applications Strict optimization.Critical point: on models with Snapdragon 8 Gen 2 (for example, Xiaomi 13 Ultra), background activity of Google Play Services can "eat up" to 5W Power. Turn off automatic app updates in the Play Market → Settings. Xiaomi model Max.

PD 3.0 (for example, Xiaomi 65W) PD 3.0, QC 3.0 5. Control the Temperature: Why 30°C is Xiaomi’s limit to automatically reduce charging power when the battery is heated above 35°C. To avoid this: ❄️ Remove the case (especially silicone or thick) Tests show that the cases increase the temperature by 5-8°C. 🌡️ Charge in a cool place. Perfect temperature — 20-25°C. Pri. 30°C+ speed 40%. 💨 Use the cooling. For emergency cases, a small one is suitable. USB-Fan (e.g. Xiaomi Mini Fan) facing the back. Check the temperature via AccuBattery or built-in monitor (Settings) → Battery → Battery condition) If the value is higher than 38°C, charging can stop completely before cooling down. 6. Update the firmware: why MIUI 14 charge faster MIUI 12 Manufacturer regularly optimizes charging algorithms in new versions MIUI. For example, in MIUI 14 added support for Adaptive Charging, which dynamically adjusts current depending on the state of the battery. How to upgrade: Go to Settings → The phone. → System Update. Click Check Updates and install the latest stable version. For manual firmware, download the file from the official website and select Update via File. If the update is not available, check the firmware region. For example, the global version (Global) may lag behind the Chinese version (China) on the Internet. 2-3 Use the Mi Flash Tool to change region (requires unlocking the bootloader). ⚠️ Note: On some models (Redmi Note) 11, POCO X4 Pro after updating to MIUI 14 Quick charging support is missing. Solution: roll back. MIUI 13 or wait for the patch. 7. Reset your battery settings (if charging suddenly slows down) MIUI It miscalibrates the power controller, causing it to charge in snatch or at low speed. To reset the settings, go to Settings. → Annexes → App management. Tap three dots in the top right corner and select Show All Processes. Find BatteryManager (or com.miui.powerkeeper), open it and click Storage. → Clear the data. Reboot the smartphone. After the first discharge 2-3 The charging cycle may be slower, which is normal. The system will recalibrate the battery. If the problem persists, try a full reset (Settings) → Additionally. → Recovery and reset, but back up first. 💡Resetting the battery controller helps in 70% cases where charging suddenly slows down for no apparent reason (for example, after updating or installing a new application). 8. Alternative methods: From Power Bank to wireless charging If standard methods don't help, try non-obvious solutions: 🔋 Power Bank with PD 3.0: Some external batteries (e.g. Xiaomi) 20000mAh 120W) They're more powerful than network adapters. Connect your smartphone to a Power Bank, and you can get faster. 10-15%. 📶 Charging from a USB-Type C monitor or laptop: Modern monitors (e.g. Xiaomi Mi Desktop Monitor) and laptops with a USB-C PD can be issued 65W. 🔄 Wireless charging: Controlled, but on some models (Xiaomi) 13 Pro, Mix 4) wireless 50W wired 33W You can combine the methods to maximize the effect, for example, use the original adapter. 120W + cable 20AWG + plane-ship + cooling with a fan. In this case, Xiaomi 14 Pro charges to 50% post 10 minutes against 15 Technically, yes, but it's very inefficient. When you connect a second smartphone through a different device. OTG-cable → Xiaomi will be fast enough. 2-5W Because of the limitations of the protocol, this is only suitable for emergency charging. 5-10%. FAQ: Frequent questions about Xiaomi charging ❓ Why does my Xiaomi charge slower than in reviews? Reviews test charging under ideal conditions: room temperature, original adapter, screen off. In reality, speed depends on: ambient temperature (optimal) 20-25°Battery states (wear-out batteries charge more slowly) Background activity (synchronization, updates, games) Use the AccuBattery app to check the actual charging power. ❓ Can an adapter be used on 120W Xiaomi, which only supports 33W? Yes, you can. A smartphone will only take the power it supports. 10 Pro (33W) when connected to an adapter 120W will charge on 33W, But don't use cheap adapters without certification, because they can damage the power controller. In some models (POCO X3) adapter PD 3.0 You may not be able to activate fast charging – you need a quick charge. 3.0. ❓ How to check battery wear? Battery capacity can be checked: Through Settings → Battery → Battery status (shows "good/medium/bad"). In the AccuBattery app (Health section shows accurate capacity in mAh ##4636## → Battery information, if the tank drops below 80% from the factory, the battery should be replaced - this directly affects the charging speed. ❓ Why does the charging stop at 80-90%? It's a normal function. MIUI It's called Adaptive Charging, which prevents overcharging to extend battery life. To turn off: Go to Settings. → Battery → Charging settings.
