Macbook air 13 inch 2013 Full charge capacity

[senc01a]

Hi everyone,
I've noticed a significant decrease of my battery life in my 13 inch macbook air 2013 haswell.
Looking at the system report, I notice that the Full charge capacity is now: 6884 mah.
Is that normal?
I think i remember that it is supposed to be something like 7500 mah, but I can't find any threads or documentation where people post theirs.
Could you please let me know if you have a similar full charge capacity?

Full charge capacity: 6884
Cycle count: 27

Thanks in advance!

It's normal for it to drop. Stop worrying about it and enjoy your machine.

Thanks for your information.
In any case, do you know what is the supposed full charge capacity?

I'm not sure what's it's supposed to be but I bought my 13" air yesterday, have yet to charge it once and it tells me the total charge capacity is 7372.

Thanks for your info.
In about 2 hours mine has gone down another 100 mah, it now shows 6786.
Im not sure if this is normal, but it is very disappointing.
Do you think I should contact the apple support and try to get a replacement?
Especially considering the following:

For the newest generation of batteries (Late 2010 and later):
Quote:
The built-in battery of your MacBook, MacBook Pro or MacBook Air is designed to deliver up to 1000 full charge and discharge cycles before it reaches 80 percent of its original capacity.

Mine is :

Design Capacity = 7150 mAH
Current Capacity = 6865 mAH

Cycles = 47 (12 weeks old)
Health = 96%

I know it's easy to get drawn into the numbers and start worrying about drops (mine has dropped 4% in the last 6 cycles) but everything I've read is telling me not to be concerned at this point.

That being said I'm gonna try and ignore the stats for now and just keep an eye on how long the battery is lasting - which for me is just as good as ever.

Especially considering the following:

Apple doesn't replace batteries under apple care unless it's defective. Mines was at 69% on 10 months, and they said it was within normal wear. Now at 64%.

For what it's worth, I have the 11" MBA (has less battery capacity than 13") and it's about a month old...

30 cycles, 5100 mAh.

I have brightness at 2 or 3 (out of 16) and it lasts me all day at work without a charge without issue...

I charge it when I get home but it's usually about 50-60% at that point so i bet it'd last well into the night.

Woah, so went down by 30% in 10 months? If it goes down by another 30% in another 10 months you'll only be at 40% capacity in less than 2 years. That's really poor is it not?

I think mines was an extreme case.. My computer is active throughout most of the day and I'm constantly traveling, unplugging, charging, draining the battery completely, changing temperatures constantly from warm indoors to freezing outdoors.

The degeneration started slowing down... about 5 months later and I only lost 5% more.

Still, I get about 3 solid hours of normal usage and I just take my power adapter if I'm going to be out for longer than that.

 

[senc01a]

I've decided to not look at the full charge capacity anymore, basically because it variates quite a lot. For instance, I might turn on the computer, see it at 6800mha, two hours later it might be at 6500, and then at 6900. Pretty large variations if you ask me. Anyway, I'm getting slightly better battery life with Mavericks the past couple of days, although not as good as I used to with ML.

Thnks for the info.

It's all over the place for me too.

I just do as you do, ignore it.

Um, that's not normal. Apple replaces batteries when they drop below 80% within AppleCare.

Mine is up and down (as normal I think):

It started dropping from a steady 100% at around 38 cycles.
