Wi-Fi consumes power even when switched off; soon after Factory Reset
Symptom
■ Steps to Reproduce
1) Factory reset the phone
2) Finish the startup widget with default values
3) Go to Settings > Battery > Tap on battery icon to see “Battery Use” details
※ Notice that “Wi-Fi” application is consuming power even if Wi-Fi is already in Off condition
Cause
■ “Location” and “Allow Wi-Fi Scanning” options are default ON after Factory Reset.
This allows the Wi-Fi applications to scan for available channels even when Wi-Fi is in Switched off condition.
How to fix
■ Switch off the “Location” and/or “Allow Wi-Fi Scanning” option
■ Steps to Switch off “Allow Wi-Fi Scanning” option:
- Settings > Wi-Fi > Options > Advanced Wi-Fi
※Note: The option can be found with different text in different models
e.g.: “Allow Wi-Fi Scanning”, “Scanning always available”
