Ans- The space the Config APK app takes up in the device's internal memory is just 20 KB. Unless malware is compromised, it should not use much of the battery's power. Because it is often set to operate in the background, its impact on the amount of battery it uses is insignificant. You might fix the issue with the battery by doing a check for malicious software. Stopping the program by forcible means and resetting the device to its factory settings are options.
