Late 2011 MBP battery life

[Megauliani]

Hi,
I have a 13" late 2011 MBP. When I purchased it I remember being able to close it, not use it for maybe 3-4 days and open it and still have at least 20% battery. This morning I unplugged it, and it lasted until now (11 hours maybe) and it's at 5%. I checked the web for specific settings but all I was able to find were guides on extending the life of the actual battery not its use while the lid is closed or in sleep mode I guess. Could anyone point me in the right direction?

Sounds like there's something else going on. You should be able to leave your machine in sleep mode for days as you describe without any problems.

It sounds like it may not have stayed in sleep mode the entire time.

For sleep issues, you may find some useful ideas here:

• Mac OS X: Why your Mac might not sleep or stay in sleep mode
• Determine why your Mac wakes up from sleep
• One sleep problem caused by printers - solved ... and another
• If your Mac isn't sleeping properly and you have gfxCardStatus installed, try uninstalling it.

This should answer most, if not all, of your battery questions:
