2012 MBA initial battery capacity not 100% issue !!

Tim - you are just going to drive yourself nuts CONSTANTLY checking multiple battery levels like this - just use the machine.

like others said, i wouldn't worry about it too much. For me, my battery has 1 cycle on it and has 78% health....definitely defective!

Part of the reason you have 78% health is you only have 1 cycle on it. You're killing your battery faster by not using it. Batteries need to be used to stay healthy. Read the AC POWER section, as well as the rest of the Apple Notebook Battery FAQ

it is brand new with 78% health right off the bat...not normal at all. The lowest I have seen right away is 90's

that is what i am doing...i was just giving insight to the initial poster that he does not need to worry about a 95% battery life....me on the other hand, has an issue.

Got it. You didn't specify in your first post that the battery was new.

:) Were you thinking I was just keeping the battery around 80% of a charge then just charging it some more never really letting it hit cycles? I typically use mine until the battery hits red before i recharge.

Some people run exclusively on AC power, rarely or never cycling their battery. Your post didn't give enough information to know for certain if that was the case. If your normal use requires running on battery until it's almost drained, by all means do so. However, it's not necessary to intentionally do that. You can plug in at any time, regardless of the percentage charge remaining.

good to know. I always was under the impression that running the battery down as low as you can is best before recharging. I guess i pretty much naturally do that since i don't take it out of the house much.
 
Just got back from the apple store...they ran some test and it was a defective battery. Now to the sweet stuff.... They said they just increased the education discount on the airs to $105 off. So you might wanna look into that.

Yup. Thats exactly what I used to do on my laptops. Now I've changed my habits and use the power plug every time instead. Hmmm.. how about the new iPad? I mean is the Lithium ion battery in iPad work the same as the new apple MacBooks? Can I plug in all the time using iPad in order to slowly down the charge cycles?

Using the power plug is the same as running on AC power. That's bad for your battery, as you need to run on battery power regularly to keep it healthy. Always plugging it in also defeats the purpose of having a portable computer with a battery. It's intended to be used without always plugging it in.

Thanks for the reminder once again. How about the case of new iPad? Is the macbook charging principle applicable to the iPad?
