Byte Size Tips: How to Disable Wi-Fi On Your Android Device When the Screen is Off

There’s probably no reason to have Wi-Fi enabled if your device is sitting there unused – and your battery life will be improved if your tablet isn’t constantly syncing in the background anyway.

Note: Obviously if you have a 3G or 4G device, disabling Wi-Fi will increase data usage and probably won’t save you any battery life unless you’ve configured your device to not sync on your mobile connection. This does work really well for a Wi-Fi only tablet though.

First head to Wi-Fi settings, pull up the Menu, and choose Advanced. Then use the “Keep Wi-Fi on during sleep” option.
