    Hi everyone - I just purchased a brand new 2012 MBA (13", i5, 8GB, 256GB) and I've been having issues with its battery life. I've only been able to get about 2-2.5 hours of battery out of it, which obviously is quite low for the MBA.

    I don't think it's a hardware issue, because when I reboot OS X in Safe Mode, the battery estimates are in the 5-6 hour range. Therefore, it must be a software problem with background processes. I migrated all of my data from my previous MBP, so all the same processes and applications were running from that one. I've uninstalled several third-party applications, but I'm not sure what exactly is causing the issue.

    Below are all the processes that run on my computer without any other applications open (I've replaced my user name with asterisks for privacy). Anyone recognize any of these processes as ones that kill battery life?

    Thanks in advance for your help!

    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.

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

    Thanks, but I've already done basically everything suggested in that FAQ. I'm wondering specifically if anyone notices any processes in my list of processes that may be causing this battery issue. Any help would be appreciated!

    It would be easier to read if you follow these instructions:
    1. Launch Activity Monitor
    2. Change "My Processes" at the top to "All Processes"
    3. Click on the CPU column heading once or twice, so the arrow points downward (highest values on top).
    4. Click on the System Memory tab at the bottom.
    5. Take a screen shot of the whole Activity Monitor window, then scroll down to see the rest of the list, take another screen shot
    6. Post your screenshots.
