    Work bought me a brand new MBP 15" about 3 months ago. It's basically used when i'm out in the field or if i need to work remote. So it's not my normal day to day machine

    When i first got it i was so impressed with the battery life. I would see like 4 to 5 hours when fully charged which for me was a big plus, commuting over an hour a day via train i could get a lot of work done.

    SO to the problem. About a week ago I started noticing the battery life was draining quite fast once disconnected from power. This being my first mac book i started looking around to see if i could find something that would make sense of this depleting battery life. In short I didn't find anything. Power consumption is set up for minimal power draw when disconnected from power (see screen shot below).

    I usually have a few programs running for work but ones i wouldn't think would be drawing that much battery life.
    - browser
    - securecrt
    - terminal
    - textedit

    Question: before closing the lid (putting it to sleep) on the MBP should i be quitting the programs? Once a sleep does it draw down on the batter?

    Additional input that might be relevant is that i have parallels installed (but not running as far as i can see) as well as MS Office 2011

    Anyone that can assist would be greatly appreciated. If i can't figure this out i'm going to have to go back to apple with this as my company spent a pretty penny on this and we should be getting more battery life out of this.

    thanks

    Sleep should not draw much power so that's most likely not the issue but running Parallels is a big drain on power that's for sure.

    Be sure to try resetting the SMC http://support.apple.com/kb/ht3964 and also monitor Activity Viewer for applications that are taking up a lot of processor capacity as the more processor usage the more power consumption.

    a SMC reset can hopefully get your battery time back up

    Did yours come with Lion/did you upgrade? If so, a SMC reset is definitely in order.
