Don't worry if your phone isn't activating Fast Charge while plugged in.
This is usually caused by the charging accessories, the environment, or system settings. The following guide will help you troubleshoot the issue and get your fast charging speed back to normal.
I. Hardware and Environment Check
1. Use the original charging kit
Please make sure you are using the original Fast Charge adapter and cable that came with your phone. Third-party or incompatible accessories may not be able to activate the specific fast charging protocols.
2. Clean the charging ports
Check and clean the charging port on your phone, as well as the connectors on the cable and charger. Make sure all connections are clean, tight, and free of dust or debris that might affect contact.
3. Check the condition of the charger and cable
Try using a different original or compatible Fast Charger and cable to test. If Fast Charge works with the new accessories, your original charger or cable might be damaged.
4. Ensure a suitable charging temperature
Fast Charge works most efficiently within a specific temperature range. Avoid charging in environments that are too cold (e.g., below 15°C) or too hot (e.g., above 35°C), as extreme temperatures can prevent Fast Charge from activating.
II. System and Software Optimization
1. Restart your phone and check the connection
Try unplugging and replugging the cable, or simply restarting your phone. A quick restart can often clear temporary system glitches or connection issues, restoring the Fast Charge function.
2. Update the system and check theme settings
Please ensure your phone system is updated to the latest version, as updates often include improvements for charging efficiency and stability. Additionally, if you are using a custom theme on your lock screen, we recommend switching back to the default system theme to verify that the Fast Charge icon is not being hidden by a display issue.
