Question: How do I calibrate my MacBook Pro battery?

I was reading about Apple Portables and Calibrating your computers battery for best performance, and I can not figure out how to calibrate my batter. I currently own a MacBook Pro 13" June 2012 model. I had also noticed that sometimes when I check the battery health it only says Normal, and when I look at iStat Pro it shows 99%, then sometimes it will show 100%. It changes every so often. I only have 27 cycles and always make sure to drain my battery and completly charge it. Please if anyone knows a solution and how to calibrate it would be greatly appreciated.

Answer:
Answer:

It is not the os that determines calibration. It's the model Macbook Pro that you have. From the link that dominic23 provided, is your model listed as one that needs to be calibrated? Did you read your user manual that came with your computer?



As for RSS feeders, search them out on the App Store, CNET Mac Downloads & MacUpdate.

I am still on Snow Leopard. It's Mail version has its own RSS feeds. Not sure if Mountain Lion's Mail still has it.

Your model Macbook Pro does not need calibration. Read the user manual that came with your computer.



Your (Apple's) System Profile information is what you should go by instead of 3rd party software. If the profiler says your battery is "normal" then it is.

I did read the owners manual and I dont see anything about calibrating my battery, but I will keep an eye on it. Do you recomend how im charging it, by always letting it fully charge and drain?


That should tell you your model notebook does not need it. I have the silver key model (5 years old) and my user manual has a chapter on calibration.


Your user manual does not explain how to properly make use of your battery or charging?
