Macs/Apples/Battery life on MacBook Air 2011



I have a Macbook Air 2011 edition with 128 GB of SSD.  Recently the battery life has been significantly declining.  I only have about 150 charge cycles, but I can only be using a word processor for about 3 hours instead of the 5 when I got it.  Any tips?

Thanks for writing! In my experience this is pretty normal, for a battery to lose the ability to charge fully or hold charge after a couple years.  You can check with Apple on the tolerance for battery failure within AppleCare to see if any replacement is covered under warranty.

Good luck!

I worked in IT for ten years with a specialty in Macintosh technologies and Project Management.
I've worked with the Macintosh Operating system and various machines since my first PowerMac 8500 running Mac OS 7.5.3 in 1996. I support my friends and family in keeping their Macs healthy and upgraded. Now I use a MacBook Pro for our home media network and we're pretty much down to iPads and iPhones for daily use.
Most important: I've also worked on PCs for a number of years with various flavors of Windows(95,98,NT4,2000,2000Server,2K3Server,SBS 2K3Server,Mil,XPHome,XPPro, Vista Business), but I've always used the Mac as my platform of preference.
