Second day with MBP and %85 Battery Health

Question

Hey guys ,
I ve just open my new MBP 2.66 and i used it for just nearly 2 days.
When i see the battery statics , they re like;
19weeks
2 cycles
battery health : 85%
It is like a joke! Just 2 days and 2 cycles how could it be possible that i ve 85% battery health on my MBP?
I think that book was made 19weeks ago , but i guess it doesnt have to affect the health of my battery , right ?
I feel so terrible atm , please somebody tell me that its normal and all MBPs are same at the beggining:)
What if it is a problem from factory , i ve apple care product on my MBP , Does it include the replacement of battery?
thanks .

Answer 1

The battery needs several weeks of use for the battery's reported health to stabilize — it's not being reported accurately before calibration. Even after weeks of use it's likely to fluctuate up and down by several percentage points from day to day and week to week. Now that you've had it for more than a month, you can't return it, and your battery probably won't be considered defective unless and until it shows less than 80% health steadily for a couple of weeks or longer. As long as it's above 80%, you will probably be told it's within specs. So there is *no use at all in obsessing about it* until then. Stop doing so.
Just use the computer normally for a month or two and see what happens. Don't check on the battery's health every day — that's obsessing. Check on it every two weeks. If it falls below 80% and stays there, take the machine in for battery testing at an Apple Store. No one can assure you that your battery will be found defective. And as I wrote above, it probably won't even be tested if its health is above 80% when you take it in.
Yes, the 19 weeks is the time since the computer's manufacture date.
