Xiaomi smartphones support fast charging technology (Quick Charge, Turbo Charge, HyperCharge), but it does not always work out of the box at maximum speed. Users often find that the device charges slower than expected, although the power supply and cable meet the requirements.
In this article, we’ll look at all the ways you can enable fast charging on Xiaomi, Redmi and POCO devices, from standard settings to hidden engineering menu features. You’ll learn how to check your current charging speed, which models support certain protocols, and what to do if your smartphone “refuses” to charge quickly even with the original adapter.
1. Compatibility Check: What fast charging is supported by your model
Before setting up fast charging, make sure your smartphone supports it. Xiaomi uses several standards, and their compatibility depends on the model and year of release. Below is a table with current data for popular devices (2020-2026):
| Model | Max. Charging power. | Protocol | Required power supply |
|---|---|---|---|
| Xiaomi 14 Pro | 120W | HyperCharge | 120W (includes) |
| Redmi Note 13 Pro+ | 120W | Turbo Charge | 120W (optional) |
| POCO F6 Pro | 90W | Quick Charge 4+ | 67W/90W |
| Xiaomi 13T | 67W | Turbo Charge | 67W (includes) |
| Redmi 12 | 18W | Quick Charge 3.0 | 10W/18W/20W |
If your model is not in the table, check the specifications on the official Xiaomi website or in the documents to the device. Note: the power supply must match or exceed the maximum charging power of the smartphone. For example, for the Xiaomi 14 Pro, it is useless to use an adapter on 67W - it does not unlock the full 120W.
Also consider cable: over 30W requires a USB-C 2.1 or USB 3.2 cable (usually bundled with flagships). Cheap USB 2.0 cables limit speeds to 10-18W.
2. Enabling fast charging through standard settings
On most Xiaomi devices, the fast charging feature is activated by default, but it can be manually disabled (for example, to save battery).
- Open the Settings. → Battery.
- Tap on Battery Settings (or additionally in older versions of MIUI).
- Find the Quick Charge option (can be called Turbo Charge or Quick Charge).
- Activate the switch.
If you don’t have a point, your model doesn’t support software management for fast charging (e.g. budget Redmis until 2021), in which case the speed depends only on the power supply and cable.
Important: Some devices (e.g. Xiaomi 12 Pro) have a separate Superfast Charging setting (for power over 60W).
Use an original or certified power supply
Check the cable for damage.
Turn off the cover (overheating reduces speed)
Close the background applications

3. Engineering menu: hidden settings for experienced users
If standard settings fail, you can try activating fast charging via the Engineering Mode, which is suitable for advanced users and requires caution - incorrect changes can lead to failures.
Instructions for MIUI 14/15:
- Open the phone app and enter the combination: ##4636##
- In the menu that appears, select Battery Information.
- Scroll down to Fast Charge Config (or similar).
- Set the Enabled or Force Fast Charge.
- Reset the device.
On some models (e.g. POCO X5 Pro) the path may be different:
##6484## → Battery → Fast Charge → EnableWhat to do if the engineering menu is not opened?
Warning: Changes in the engineering menu can cause the battery to overheat or accelerate wear. Do not increase the current/voltage values above the factory.
💡
After activating fast charging via the engineering menu, check the battery temperature in the AIDA64 or AccuBattery app. If it exceeds 45°C, turn off the function and use the standard mode.
4. Charging control applications: AccuBattery and alternatives
If you don't want to dig into the settings, you can use third-party charging utilities. The most popular app is AccuBattery (available on Google Play), which not only shows the current charging speed, but also allows you to limit the maximum level of charge (useful for extending battery life).
How to use:
- 📊 Install AccuBattery and provide all necessary permissions.
- 🔋 Go to the Charging tab – here the current power in mA (milliamps) is displayed).
- ⚡ If the speed is lower than expected (for example, 1000 mA instead of 3000 mA), the problem is in the power supply or cable.
- 🛠️ In the Health tab, you can configure the charge limit (for example, up to 80%).
Alternatives:
- Battery Guru monitors temperature and voltage.
- Ampere – shows the exact value of the charging / discharging current.
- 3C Toolbox – for advanced users (requires root).
Importantly, apps can't unlock fast charging unless it's supported by hardware, but they can only help diagnose problems.
5.Problems and Solutions: Why Fast Charging Doesn't Work
If you’ve set everything up but your smartphone is still charging slowly, check out the following points:
| Problem. | Possible cause | Decision |
|---|---|---|
| Charging "hangs" by 80-90% | Protection against overheating (Adaptive Charging) | Turn off in Settings → Battery → Optimization of charging |
| Speed below 10W | Unoriginal cable/power supply unit | Use certified accessories |
| The phone is warming up and slowing down. | Background processes or games | Close the applications, reduce the brightness of the screen |
| Fast charging only works up to 50% | Battery wear (capacity < 80%) | Replace the battery at the service center |
Critical error: If the smartphone shows a message “Charge suspended” when you connect a powerful adapter, this may indicate damage to the power controller, in which case a diagnosis is required in the service.
Another common problem is limiting charging at low temperatures (below +10°C), in which case Xiaomi blocks fast charging until the device warms up.
- 🔥 Place your smartphone in a warm place for 10-15 minutes.
- 📱 Use a heated cover (for example, for winter use).
- ⚙️ Disable protection via the engineering menu (not recommended!).
💡
If fast charging stopped working after the MIUI update, try resetting the battery settings: Settings → Applications → Application Management → Three points → Reset settings.
6. How to extend the battery life when using fast charging
Fast charging is convenient, but it speeds up battery wear due to increased temperatures and currents, to minimize damage:
- 🔄 Don’t keep your smartphone on charge after 100% – turn it off immediately after full charge.
- 🌡️ Avoid charging at temperatures above 30°C (Do not leave your phone in the sun or near heat sources).
- 🔋 Use Optimized Charging (in battery settings) to limit your charge to 80% in everyday mode.
- ⚡ For long-term storage (such as a spare phone), charge the battery to 40-50% and turn off the device.
Signs of battery wear:
- 📉 Rapid charge drop (from 100% to 80% in 30-60 minutes).
- 🔥 Overheating when charging or using.
- ⚡ Charging “jumps” (for example, from 50% to 30% after rebooting).
- 🛑 The phone turns off at 10-15% charge.
If the battery capacity has fallen below 80% of the original, a replacement is recommended.
#4636## → Information about the battery → Wear level💡
For models that support wireless charging (such as the Xiaomi 13 Ultra), use only original wireless chargers. Cheap counterparts can damage the power controller.
7.Fast charging on older Xiaomi models (until 2020)
Devices up to MIUI 12 (e.g. Xiaomi Mi 9, Redmi Note 8 Pro) often don't have a separate fast-charging switch in the settings.
- Make sure you use a power supply that supports Quick Charge 3.0/4.0 (e.g., the original 18W).
- Check the cable – it should support data transfer (not a “charge” cable).
- Update your firmware to the latest version of MIUI (older versions may have software limitations).
- If nothing helps, try resetting to factory settings (Settings → About Phone → Resetting).
On some models (e.g. the POCO F1), fast charging only works when the screen is off. This is normal behavior, which is how heat is reduced.
Note: On devices older than 3-4 years (e.g. Redmi 5 Plus), fast charging may be disabled at the firmware level due to battery degradation, in which case only a battery replacement will help.
