Xiaomi smartphones are famous for supporting ultra-fast charging technologies – from 33W in budget models to a record 210W in flagships like Xiaomi 14 Pro or Redmi Note 13 Pro+ 5G. However, many users are faced with the fact that the device charges slower than stated characteristics. The reasons lie not only in a faulty power supply, but also in hidden MIUI settings, temperature restrictions or even in the firmware.
In this article, we’ll explore all the ways to activate the maximum charging speed, from basic checks to advanced tweaks through the engineering menu, how to get around system limitations, what accessories actually support the declared watts, and why even the original cable sometimes slows down the process, and also a unique method of resetting the power controller, which Xiaomi does not advertise in the official instructions.
1. Compatibility Check: Does your Xiaomi support ultra-fast charging?
Before you try to enable ultrafast charging, make sure your model supports it. Xiaomi uses several standards:
- 🔋 Fast Charge 3.0/4.0+ (18–33W) — Redmi budget series 10/12, POCO M/X.
- ⚡ Turbo Charge (67–120W) — Xiaomi 11T Pro, Redmi Note 12 Pro+.
- 💥 HyperCharge (120–210W) — Xiaomi flagships 13/14 Ultra, Mix Fold 3.
The full list of models with support for high power:
| Model | Max. power (W) | Technology |
|---|---|---|
| Xiaomi 14 Ultra | 90W (wireless) / 80W (wireless) | HyperCharge |
| Redmi Note 13 Pro+ 5G | 120W | Turbo Charge |
| POCO F6 Pro | 120W | Turbo Charge |
| Xiaomi 13 Lite | 67W | Fast Charge 4.0+ |
| Redmi K70 Pro | 120W | HyperCharge |
⚠️ Note: If your model is not on this list, attempts to force charging can cause the battery to overheat or the controller protection to go off. 9A No longer physically supports 10W, And no amount of customization will change that.
2. Basic conditions for ultrafast charging: power supply, cable, temperature
Even if your smartphone supports 120W, it won’t charge at top speed if:
- 🔌 Uses a non-original power supply (for example, from the old Redmi Note 8 Pro instead of the original power supply). 120W-kit-adapter).
- 📱 Battery temperature above 40°C or below 10°C — MIUI automatically reduces the power.
- 🔗 The cable doesn't support USB Power Delivery 3.0 or Quick Charge 4+.
- 🔋 Power saving mode or "Optimization of charging" in settings is enabled.
How to check the current charging power:
- Connect your smartphone to the charger.
- Open the Settings. → Battery.
- Click on the icon. ⚡ Next to the percentage of charge – the current power will appear (for example, “Charging: 87W").
💡 Useful tip: If power is lower than expected, try turning the cable over in the port USB-C — Sometimes the contact is oxidized on one side.
☑️ Preparation for ultra-fast charging
3. Enabling ultra-fast charging in MIUI settings
Most Xiaomi models activate the function automatically when you connect a compatible adapter, but sometimes you need to manually configure:
Method 1. Through the battery menu:
- Go to Settings. → Battery.
- Slip on Battery Settings (or "Advanced" in older versions of MIUI).
- Find the option “Fast Charging” or “Ultra-Fast Charging” and turn it on.
Method 2. For models with HyperCharge (120W+):
- Connect the original power supply.
- When the notification "Allow ultrafast charging?" appears, click "Allow".
- If the notification does not appear, restart the smartphone and reconnect.
⚠️ Note: On some firmware (for example, MIUI 14 for global version) option hidden, in which case the resetting of the battery settings will help:
Settings → Applications → Application Management → Three points (⋮) → Application Resetting → Select Battery4. Hidden settings: engineering menu and ADB-team
If standard methods don’t work, you can activate ultrafast charging via an engineering menu or ADB. These methods are suitable for advanced users!
Method 1. Engineering menu (for models on Snapdragon):
- Open the Phone app and type ##4636##.
- Go to Battery Information.
- Find the "Fast Charge Config" option and set the "Enabled" value.
- HyperCharge may require an additional “Super Charge” setting.
Method 2. ADB-teams (requires PC):
- Connect your smartphone to a computer with USB Debugging enabled (Settings → About Phone → MIUI version – press 7 times to unlock the developer mode).
- Enter in command line: adb shell settings put global fast_charge_forced_enable 1 For HyperCharge add: adb shell settings put global super_charge_forced_enable 1
- Reset the device.
⚠️ Attention: Wrong commands ADB This can cause you to reset your settings or damage your firmware. Before experimenting, back up through Settings. → Additionally. → Backup and reset.
What to do if after ADB-The smartphone commands are not turned on?
5.The solution to the problems: why Xiaomi is not charging at top speed
If after all the manipulations the charging power remains low, check these points:
| Problem. | Reason. | Decision |
|---|---|---|
| Power 'stuck' at 18W | Power saving mode activated | Turn it off in Settings → Battery |
| Charging jumps (60W, 10W) | Poor contact in the USB-C port | Clean the port with alcohol or replace the cable |
| The inscription "Charging suspended" | Battery overheating (>40°C) | Let the smartphone cool for 10-15 minutes |
| Maximum 33W instead of 120W | Unoriginal power supply | Use only the adapter from the set |
Hidden problem: Some models (such as the Xiaomi 12 Pro) reset the power controller settings after the MIUI update to return the top speed:
- Connect your smartphone to charging.
- Reboot it in charging mode (without turning off the cable!).
- After turning on, check the power in Settings → Battery.
💡 If you use wireless charging, remember: even with support 80W The real speed will be 20 to 30 percent lower because of energy loss. For maximum efficiency, place your smartphone strictly in the center of the charging station.
6. Charging optimization: how to extend battery life when using HyperCharge
120W+ technologies put a lot of stress on the battery, reducing its lifespan.
- 🔄 Don’t keep your smartphone charging after 100% – turn it off immediately after you reach the maximum.
- ❄️ Avoid charging at temperatures below 10°C or higher than 35°C.
- 📉 Enable “Optimized Charging” in battery settings (limits charge to 80% at night).
- 🔋 Calibrate the battery once every 3 months: discharge to 0%, then charge to 100% without interruptions.
⚠️ Note: If the battery capacity (checked in Settings) → Battery → Battery status has dropped below 80 percent, and HyperCharge will accelerate its degradation. 33W.
💡
Ultra-fast charging is convenient, but reduces battery life by 15-20% per year of active use, and the optimal balance is to use 120W only when it is really necessary (for example, before an urgent trip).
7.Alternative methods: firmware and modified cores
For enthusiasts willing to risk the warranty, there are unofficial ways to unlock additional charging modes:
Method 1. Castom firmware (TWRP + Magisk):
- 📱 Install. TWRP Recovery and firmware on the base AOSP (For example, Pixel Experience or LineageOS).
- 🔧 Install Magisk module with a patch for the power controller (e.g., "Fast Charge Enabler").
- ⚡ In some firmware, the option “Force Fast Charge” appears in the battery settings.
Method 2: Modified cores (for Snapdragon):
Cores like Kirisakura or Perseus allow:
- 🔋 Turn off temperature restrictions.
- ⚡ Force charging to 120W even in the models 67W (For example, Xiaomi 11 Lite NE).
- 📉 Set up threshold current/voltage values.
⚠️ Note: These methods are warranty-free and can lead to:
- 🔥 Overheating and bloating of the battery (especially when using non-original batteries).
- 💥 Failure of the power controller (repair will cost 30-50% of the cost of the smartphone).
- 🚫 Locking charging after updating MIUI.
💡
Before installing custom firmware, check its compatibility with your model on the 4PDA or XDA forums. For example, the firmware for the Redmi Note 12 Pro+ will not be suitable for the Redmi Note 12 Pro due to different processors (Snapdragon vs Dimensity).
