Well, my Mid 2009 13 inch Macbook Pro is starting to show it's age. Granted, it has been used almost daily since September 2009 but it has started to have rather poor battery life (at least compared to when it was new). I wanted to find a way to see how many charge cycles it has completed. It is at 282, which isn't that many, and far less than Apple claimed. However, I am really not that upset because of how often it has been used. I never expected to get 1000 charge cycles out of a laptop, but it would have been nice if I would have gotten a little higher than 282.
If you would like the steps on finding out how many charge cycles your machine has then you can follow these steps.
- Your first step will vary depending on which version of Mac OS X you are using:
- Mac OS X 10.6.8 Snow Leopard or earlier: Open Apple System Profiler by choosing About this Macfrom the Apple () menu. Then, click More Info.
- OS X Lion 10.7 or later: Open System Information by choosing About this Mac from the Apple () menu. Click System Report.
It should look like this...
So, if you have having shortened battery life you should see how many cycles your machine has gone through. If any of you are having issues similar to me I'd love to hear about it in the comments.
