Xiaomi smartphones are famous not only for affordable prices, but also for advanced technologies โ€” including support for fast charging. However, many users face a situation where the device charges longer than the stated time or does not use maximum power at all, the reason often lies in the wrong settings, outdated software or incompatible accessories.

In this article, we will analyze all the ways to activate fast charging on Xiaomi, Redmi and other phones. POCO - from basic settings MIUI to the hidden parameters of the engineering menu. Youโ€™ll learn how to check your current charging speed, which cables and power supplies are actually working, and how to avoid overheating and degradation. Particular attention will be paid to models with HyperCharge support.120W/200W) and Turbo Charging, where the setting has its nuances.

Important: the procedure may vary depending on the version of MIUI (13, 14 or HyperOS) and the smartphone model. We will cover current solutions for devices 2022-2026, including flagship Xiaomi 13/14, Redmi Note 12 Pro+ and POCO F5 Pro.

1. Check your model's fast charging support

Before you set up, make sure your Xiaomi smartphone supports accelerated charging technology at all. The manufacturer uses several standards:

  • ๐Ÿ”‹ Quick Charge 3.0/4+ โ€” up to 18W (Budget models Redmi 9/10, POCO M3/M4)
  • โšก Fast Charging โ€” 33W (middle line: Redmi Note 11/12, Xiaomi 11 Lite)
  • ๐Ÿš€ Turbo Charging โ€” 67W/120W (flagships: Xiaomi 12/13 Pro, Redmi K50)
  • โšกโšก HyperCharge โ€” 120W/200W (top models: Xiaomi 11T Pro, Redmi Note 12 Pro+ 5G)

Find out the exact charging power for your model:

  1. On the official website of Xiaomi in the section of characteristics of the device.
  2. In documents out of the box (look for inscriptions like Max 67W or 120W HyperCharge).
  3. Through the AIDA64 application (Battery section โ†’ Charging level).

If your smartphone supports, for example, 33W, but the set was a power supply for 18W โ€“ to get the maximum speed you need to buy the original adapter Xiaomi with the right power.

3. Checking the actual charging speed

Activating the option in the settings does not guarantee that the smartphone is actually charging at maximum power.

  1. Connect the original charger.
  2. Open the Ampere app (free on Google Play).
  3. See the value in the Charge rate section (e.g. 3.5A @ 9V = 31.5W).
  4. Compare the power of your model (see section 1).

If the actual power is lower than expected, the reasons may be as follows:

  • ๐Ÿ”Œ Uses a non-original cable/power supply.
  • ๐Ÿ“ฑ Power saving mode or battery optimization is enabled.
  • ๐Ÿ”ฅ Battery temperature exceeds 40ยฐC (charging is automatically limited).
  • ๐Ÿ› ๏ธ The USB-C connector or contacts are damaged.

Critical information: HyperCharge (120W/200W) models require a complete cable to reach maximum power, which has additional contacts to transmit data about supported protocols.

What if the Ampere shows 0mA?
If the app displays 0mA when the charger is connected, try: 1. Reboot the smartphone. 2. Clean the USB-C connector with compressed air or a wooden toothpick. 3. Check the power supply on another device. 4. Update the firmware through Settings โ†’ About the phone โ†’ System Update.

4.Optimizing charging for maximum speed

Even if fast charging is activated, its speed may be limited by background processes.

Removal of background processes

  • ๐Ÿ“ต Close all applications through Recent โ†’ Close all.
  • ๐ŸŽฎ Turn off auto-update apps in Google Play.
  • ๐Ÿ“ถ Activate Flight Mode (reduces the heating of the communications module).

Battery settings

  1. Go to Settings โ†’ Battery โ†’ Battery Mode.
  2. Choose Performance (instead of Balanced or Saving).
  3. Turn off Adaptive Charging (if any) โ€“ it limits current to save capacity.

Temperature control

FAQ: Frequent questions about fast charging Xiaomi

Can I use a 67W power supply for a model that only supports 33W?
Yes, you can. A smartphone will only take the power it supports, but a 67W power supply won't speed up charging, because the top speed is limited to the controller in the phone.
Why does fast charging only work up to 80% and then slow down?
This is normal behavior. After 80%, Xiaomi automatically reduces the current to reduce heat and extend battery life. If you need to charge up to 100% faster, turn off adaptive charging in the settings.
Can I turn on the fast charger on the Redmi 9A?
No. The Redmi 9A only supports standard 10W charging. Fast charging is not implemented hardware.
What if the MIUI update has lost fast charging?
Try: Reset your battery settings (Settings โ†’ Applications โ†’ Application Management โ†’ Settings Reset) Update to the latest firmware version. Reverse to the previous MIUI via Fastboot. If nothing helps, contact the service center (possibly a failure in the power controller).
Can I use wireless charging on Xiaomi?
Yes, but only on models with Qi support (e.g. Xiaomi 13/14 Pro, Mi 11 Ultra) The maximum wireless charging power is 50W (on Xiaomi 13 Pro), but a special Xiaomi Wireless Charger station is required.
