Macbook 12 battery health at 84%

Received mine on Monday and the battery showed 16 load cycles, even before I had connected it to the power adapter. This was from my opening it straight out of packaging. Go figure.

 

That would make me suspicious. I would even think maybe it was a return and then repackaged as new.

Where did you buy it?

 

I believe this issue will eventually be in the apple exchange and repair program, just like the recently announced program for the delaminating AR coating.

Just give it some time. I wouldn't be surprised if Apple is already working on a solution and gearing up for the exchange in the background.

 

Ordered it from Apple. I made an appointment tomorrow at the local store to have it checked out. I'm of a mind just to return it and get a different one.

 

Start speaking with Apple support, your case will be logged, which is important for the future. If the rMB is not meeting what Apple prescribes inform them that it is impacting your usage and ask what are they going to do about it. I have seen some posts here regarding battery performance and Apple eventually changed the Logic Board due to a bad voltage regulator.

Q-6

 

Got my replacement machine in today. Came this time with 2 cycle counts on the battery, and 96.6% design capacity.

 

have it serviced by Apple.
Absolutely not normal to have battery life below 90% after 6 months...

wow, bring it back

 

That's definitely not good. Just checked my April 2010 white MacBook. It's been charged 2200 times and battery health is 80.4% Pretty good!

 

Supposedly, Applecare will replace batts under 80% capacity. We now have two ribs and love them. but I'll be buying Applecare for both. If they dip under 80% in the next 3yrs, we'll get Apple to make it good. So, at least I know we'll have 80% three years from now, which isn't bad. Given where they are now, I'm guessing that will put us in the 5 1/2-6 hour range.

 

Likewise. I will buy applecare right at the end of the first year. If the battery dips below 80% they will replace it.

 

Mine is currently at 83.3% after 41 load cycles and apple support via phone said that was well within normal limits. I plan to watch it for a few more months and take it by a Genius Bar to see their opinion.
