I use S2UL along with the "lock buttons when screen is off" setting to prevent excessive power drain or doing unwanted things when the device wakes up on its own.

For example if you receive a txt message or the phone rings then the screen activates and you can accidentally do all kinds of things, including running down your battery. S2U2 not only protects the screen and buttons but also has a setting to time out the device much sooner.
