Add Better Sleep to Your MacBook with SmartSleep

Lifehacker:

“Mac OS X only: Freeware application SmartSleep adds a preference pane
to your Mac laptop’s system preferences to enhance the usefulness of
your Mac’s sleep states. It does so by dynamically adjusting the type
of sleep state your MacBook will use based on your battery life. For
example, as long as your Mac’s battery has more than a 20% charge or 20
minutes remaining, SmartSleep will tell your Mac to sleep but not
hibernate. This will sleep your laptop very quickly, but it will also
keep your data in your RAM, which means your battery will still be
draining slightly while you’re sleeping. Below 20% will switch to sleep
and hibernate mode, which saves your system state to the hard drive,
thereby preserving more battery. Last, if you’re at under 5%,
SmartSleep will hibernate only. SmartSleep is freeware, Mac OS X only.”
