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?
