How Many Cycles Does a MacBook Battery Last

So based on what I'm seeing here it is ok to run my new MBA on battery almost every day?

Run on battery whenever you need to and plug it in whenever you can. You can plug or unplug any time you need to, regardless of the charged percentage, and you never need to completely drain your battery. Just make sure you don't run on AC power exclusively, as your battery needs to be used regularly to stay healthy. Read the Apple Notebook Battery FAQ for more details.
 
If you are looking for huge cycles, mine got 2302...

My early 2011 MBP has 568 cycles, and is only capable of storing 41% of its design capacity. Compared to some of the numbers I've seen in this thread, this seems somewhat lower. Anybody know whether this is far-enough from the expected behavior to warrant a free replacement, or am I stuck paying for it myself?

If it's still covered by AppleCare, yes, Apple should replace it free, as it's under 80% health before 1000 cycles.
 
Anybody here still using the Early 2009 Unibody 17" MacBook Pro? :confused:

Mine is 56 months old and holding 63% Battery Capacity after 814 cycles.. :)

Mine is down to 75% after 148 cycles and 16 months. Should I be asking questions?

The batter shouldn't be below 80% after three years according to Apple representative I talked to last time I visted their shop. He said you can have it replaced if it is otherwise. I'd be knocking on them if I were you.

Apple makes no warranties about how many years a battery should last. If it drops below 80% before 1000 cycles, it may be considered defective, regardless of the time frame. See the FAQ link in post #576 for details.

woo!

38 months
1,359 cycles (wow)
capacity 96%

i must doing something right... which shocks me. but i guess i do try to avoid leaving the charger in.

edit: unless i'm not calibrated... i have no clue? but it runs fine and seems to last a while. i always run it until the battery gets down to 2 minutes or so or dies, and then i plug in the charger. (apparently i've done this 1,359 times.) should it be relatively calibrated?

update

57 months
2,021 cycles
capacity 94%

cool

----------

that said, my design capacity is only 4100 mAh, so even with the high %, my capacity isn't that great
 
I have a MacBook Pro (Retina, Mid 2012). AppleCare has expired.
macOS says Service Battery.

Coconut Battery says manufactured in 2015-05-19, 996 cycles, 74.2% of design capacity.

From what I understand, under 80% for less than 1000 cycles is "defective".

Will Apple do anything at this point, since it's so far out of warranty?

I don't want to buy a new battery for a 6.5 year old computer. It's still great, but I'd rather put the $ towards a new one.

No. Batteries degrade naturally with both age and use. Apples warranty on the battery is 1000 cycles or 3 years (if AppleCare+) whichever occurs first. After that they aren’t liable anymore.

It says service battery because it's gone below 75%. On a good day it might go above 75% again, and the service battery warning will go away again! Don't worry about replacing it, my battery lasted about 3 more years after saying service battery before it was dreadful to use.
