Yes, Finally this is the Software that you were waiting for. This software tends to save your battery from draining overnight my putting your phone on deep sleep.
When you open the app you will see 6 options, Gentle, Strong, Balance, Aggressive, Slumberer and Custom, which have their own options. You can click on their respective tabs and check for their options.
Gentel option is the least effective as it wakes up every 30 minutes for 1 minutes to update your phone and Slumberer is the high effective as it always goes to deepsleep while the screen is off.
On Custom you can choose your options for Deepsleep weekday or Deepsleep Weekend. But you need Pro version for that, which you can find on the Android market for not more than $2.
