Overview of the Problem
When an Android device enters sleep mode, numerous processes are temporarily halted to conserve battery. This often includes disabling Wi-Fi connectivity, which means the device will not maintain a connection to the internet while it is idle. While this feature is designed to prolong battery life, it can lead to complications for users who wish to stay connected to their Wi-Fi network, especially during prolonged inactivity.
Possible Causes
Several factors contribute to the Wi-Fi turning off when the screen sleeps:
Battery Saving Features: Many Android devices come with battery optimization settings activated by default. These features can automatically disconnect Wi-Fi when the device is not in active use.
Power Management Settings: Specific configurations related to the Wi-Fi adapter might cause it to turn off to save power. Depending on the device and Android version, the default settings may vary.
Software Bugs: Outdated firmware or software glitches can create erratic behavior, including Wi-Fi disconnections during sleep.
User Configuration Mistakes: Certain configurations set by users can inadvertently lead to connectivity issues.
