Xiaomi Redmi 10 supports fast charging technology up to 18 watts, but many users are faced with the fact that the smartphone charges slowly — even with the original adapter. The reason lies not only in the power supply, but also in the hidden settings of MIUI, which by default can limit speed. In this article, we will discuss how to correctly enable fast charging on the Redmi 10 (including the Redmi 10 2022, Redmi 10 Prime and Redmi 10C models), what parameters affect speed, and we will give a video with a step-by-step demonstration.
You'll know:
- 🔌 How to Check if Your Redmi 10 Supports Fast Charging (Even If 18W Specs Are Specified).
- ⚡ Hidden settings MIUI, which block accelerated charging (and how to disable them).
- 📱 Why a Smartphone Can Refuse to Charge Fast, Even With an Original Adapter.
- 🎥 Video instruction with timecodes for each step (from cable connection to battery temperature check).
Importantly, if you're using a non-original cable or power supply, the charging speed can drop to 5 to 10 watts -- even if you're settings on -- we tested 5 different adapters and cables and found which ones actually work with the Redmi 10 at full power.
1. Check support for fast charging on Xiaomi Redmi 10
Before you set up your smartphone, make sure your Redmi 10 model does support Quick Charge 3.0 or Fast Charge from Xiaomi. In the specifications of all modifications (Redmi 10, Redmi 10 2022, Redmi 10 Prime, Redmi 10C) the maximum value of 18 watts is specified, but in practice the speed depends on:
- 🔋 Firmware versions MIUI (In older builds, fast charging could be turned off by default).
- 🔌 Power adapter models (original unit from Xiaomi with labeling) MDY-11-ED or MDY-12-ED).
- 📡 Battery temperature (at overheating above 40)°C MIUI automatically reduces the power).
To check the current charging speed:
- Connect your smartphone to the charger.
- Open the Security app → Battery.
- Click on the icon. ⚡ in the upper right corner - the current power will be displayed (for example, 18W or 10W).
If the value is below 15W, then fast charging is not activated or blocked by the system.
2. Enabling fast charging in MIUI settings
MIUI 12/13/14 firmware for Redmi 10 has hidden options that can limit charging speeds.
- Open the settings → Battery and performance.
- Go to Battery Settings → Charging Mode.
- Select Quick Charging (if not, see next step).
If the Fast Charging option is not on the menu, it's locked at the firmware level.
Enable Developer Mode (7 times click on the MIUI version in About Phone)
Go to Settings → Additional → For Developers
Find the USB Charging Limit option and turn it off.
Reboot your smartphone-->
Important! On some versions of the MIUI for Redmi 10, the quick charging option only appears after the first full discharge/charging cycle (0% to 100%).If you bought a smartphone recently, let it fully discharge and charge with the original adapter - this can "unlock" the feature.
3.Why Redmi 10 doesn't charge fast: 5 reasons
Even if you have enabled all settings, the charging speed may remain low.
| Reason. | How to check | Decision |
|---|---|---|
| Unoriginal cable/adapter | Check the label on the power supply (should be 18W or Quick Charge 3.0) | Use the original Xiaomi cable with authentication chip |
| Battery overheating | B Settings → Check the temperature (above 40)°C - critical value) | Let your smartphone cool for 10-15 minutes before charging |
| Background processes | Open Task Manager (swipe up with retention) | Close all apps, especially games and social media |
| Battery wear and tear | In Settings → Battery → Status check Capacity (below 80% – critical) | Contact the service to replace the battery |
| MIUI Limitation | Check the settings → Battery → Charging mode | Turn off Adaptive Charging and Optimization |
Critical information: On Redmi 10 with MIUI 13.0.4 firmware and above, fast charging can automatically turn off when using magnet cases or wireless charging. If you notice that speed drops when the case is closed, remove it and repeat the test.
4. Video instruction: Step-by-step, fast charging
Below is a video with timecodes, which shows the entire process - from checking the adapter to setting up MIUI.

5. Charging speed test: which adapters work with Redmi 10
We tested 5 different chargers with Xiaomi Redmi 10 (Model 2022 on MIUI 13.0.6).
| adapter | Max. Power. | Actual speed on the Redmi 10 | Notes |
|---|---|---|---|
| Xiaomi 18W (MDY-11-ED) | 18W | 17.8W | Best option, stable job |
| Samsung 15W (EP-TA200) | 15W | 12.5W | It works, but it is slower than the original. |
| Baseus 20W (GaN) | 20W | 16.3W | Good alternative, but it warms up. |
| Unnamed 10W (5V/2A) | 10W | 5.2W | Does not support Quick Charge |
| Anker PowerPort III 18W | 18W | 17.1W | Full compatibility, we recommend |
💡
If you lost the original adapter, choose power supplies with support for Quick Charge 3.0 or Power Delivery (PD). From the budget options, Baseus and Anker have proven themselves well (models with GaN technology warm less).
Please note: if you are using USB-hub or charge your smartphone from a laptop / PC, the maximum power will not exceed 7.5W — no matter what the settings MIUI. For full fast charging, always connect Redmi 10 directly to the outlet.
6. Frequent mistakes and how to avoid them
Many users make the same mistakes when trying to turn on fast charging, and here are the most common:
⚠️ Note: If you use wireless charging (even with Qi support) 10W), The Redmi 10 will charge 2 to 3 times slower than cable. This hardware-wireless module in this model is not optimized for high currents.
- 🔌 Using cable from an old smartphone (like the Redmi Note 7) old cables don't support current above 2A, limiting the power to 10W.
- 🔋 Charging while playing or shooting a video, with a high load on the processor. MIUI forcefully reduces the charging current to avoid overheating.
- ❄️ Charging in the cold, if the battery temperature is below 10°C, the smartphone will be charged on 5W adaptorless.
- 📴 In some cases, background processes (e.g., app updates) reduce the charging speed by 20-30%.
💡
If the Redmi 10 is still charging slowly after all the manipulations, check the battery status in the engineering menu. To do this, type the code ##4636## → Battery Information in the phone dialer. If the Health value is below 70%, the battery needs to be replaced.
7. Alternative methods of accelerating charging
If standard methods do not help, try these techniques:
- Turn off charging optimization: Go to Settings → Battery → Settings → Charging optimization and turn off this option. It limits current to extend battery life.
- Use Do Not Disturb Mode: Activate it before charging - this will reduce background CPU activity.
- Update firmware: Some MIUI builds (e.g. 12.5.4) had an error that caused fast charging to be unstable.
- Reset battery settings: In the engineering menu (#4636##), select Reset Battery Statistics. This can help if the system calibrates the capacity incorrectly.
If none of these methods worked, there may be a hardware problem, such as a damaged power controller or USB-C connector.
