Charging your phone involves energy conversion, which generates heat. This is especially noticeable when using high-power fast charging. To protect the battery, the system automatically adjusts performance when the temperature rises. This is a normal safety mechanism. Here are some suggestions to improve your experience while charging.
I. Optimize Your Charging Habits
1. Avoid Using High-Performance Apps While Charging
Charging naturally produces heat. If you simultaneously run demanding apps like large games, video recording, or live streaming, the temperature will rise further. This triggers the system's thermal protection, which may slow down the phone (causing lag) to prevent overheating.
Suggestion: Try to avoid heavy usage while charging, or wait until the battery is charged and unplugged before using demanding apps.
2. Use Original Charging Equipment
Non-original chargers may have unstable current or incompatible power output, which can cause the touchscreen to glitch or the system to act strangely.
Suggestion: Always use the original adapter and cable provided with your phone to ensure safe and efficient charging.
II. System Maintenance and Updates
1. Keep Your System Updated
We continuously optimize the system's temperature control strategies and performance management. Installing the latest updates can improve stability and reduce heating issues.
Path: Go to Settings > About Device > Click the top card to check for updates.
2. Clear Background Apps and Restart
If the phone lags while charging even when you aren't doing much, it may be due to low memory caused by too many background apps.
Suggestion: Close unused apps running in the background or restart your phone regularly to clear the cache and restore smooth performance.
If the problem occurs frequently, it is recommended that you bring your purchase certificate to the realme Customer Service center for testing.
