Wi-Fi Sleep Policy Manager в Android Market

Wi-Fi Sleep Policy Manager (v. 1.1) Разработано JustinJ

Manage the wi-fi sleep policy based on connection status.
Android allows you to adjust the wi-fi sleep policy, this app allows you to adjust the policy based on whether you are connected to a wi-fi network or not.

This can save a huge amount of battery, by allowing your device to use wi-fi exclusively when available, but restricts the device from constantly scanning for wi-fi when disconnected.
