LifeHacker: Plenty of apps save your battery life, but this one takes the idea to a whole new level

How Deepsleep Battery Saver works

Deepsleep battery saver constantly puts the device to deepsleep mode while screen off. During deepsleep mode, Wifi, 3G are turned off, background apps are stopped. Therefore, most apps are not working, including Facebook, Google Service, etc,. It then constantly wakes up in order to download email, sync Facebook status, etc,. It's defined by deepsleep frequency and woke up duration

In advanced mode, you can customize more parameters, including day/night settings, active period, screen timeout, sync strategy, ignored apps, etc,.

By constantly put device into deepsleep mode, we will save battery life due to no Internet connection, and therefore most of network-based apps, such as Facebook, Gmail will not work.

Caution: during deepsleep mode on, this app may disrupt your normal activities, such as your email notification comes with larger delay.
