If your battery level goes down even while plugged in, please do not worry.
This typically happens when the phone is consuming more power than the charger can provide at that moment. It is usually related to heavy usage during charging, environmental factors, or the charging accessories used.
The following guide will help you solve this issue.
I. Usage and Accessories Check
1. Avoid high-power usage while charging
Using demanding apps like 3D games, video streaming, or navigation while charging consumes a significant amount of power. If the power consumption exceeds the charging speed, the battery percentage will drop. We recommend letting your phone charge with the screen off for the fastest recovery.
2. Use original charging accessories
Non-original chargers or computer USB ports often provide very low current. If you are using these low-power sources while using the phone, the battery will drain. Please ensure you are using the original adapter and cable provided with your device to ensure a sufficient power supply.
3. Close background apps
Apps running in the background may be consuming power without you noticing. Please tap the multitasking button and clear all background applications to reduce the load on the system and allow the battery to charge properly.
II. Environment and System Check
1. Check for overheating
If the phone becomes too hot, the system will automatically reduce or stop charging to protect the battery and components. This safety mechanism, combined with power consumption from the screen and processor, can cause the battery level to drop. Please move the phone to a cooler environment and avoid using it until it cools down.
2. Clean the charging port
A poor connection can result in unstable charging or very slow charging speeds that cannot keep up with power usage. Please check the charging port for dust or lint and clean it gently with a dry, soft brush to ensure the cable makes full contact.
3. Restart the phone
Sometimes, a system process may get stuck and consume abnormal amounts of power. Restarting your phone will close all running processes and return the system to a normal state, which often resolves charging abnormalities.
