In certain cases, the device may indicate a full charge but then report a low battery shortly after being unplugged .​

3. Error Messages

The appearance of specific error codes, such as Error 13 or Error 14, can be indicative of battery-related issues. These errors often suggest that the battery is not functioning correctly and may need replacement .​
