Battery life help? CoconutBattery pic included. Just got this and...

Just got this Macbook Pro on April 15th, is this normal to lose 5% of my maximum charge in 11 cycles? I love the Mac, but I like taking it to friends houses and various public places; if I wind up having the replace the battery every 100 cycles, then I might go back to staying home on the desktop.

Seems fine to me. It'll probably fluctuate a few percentage points anyways. Mine has ranged from 90-95% over the past few days.

Just a newbie question 😀
But for "cycle" it means a "full charge" or just charging it for like 1 hour is considered a "cycle"?
And charging it for just a little time is harmful?

Charging it just a short time is not harmful.

So it's normal for me to lose 5% every ten cycles? Damn. Up to twelve cycles now and coco says I have 94%.

It goes up and down all the time.
Try a recalibration and see if it goes to 100% again.
MIne have been going from 6800-7100 from charge to charge.
From apple.com:

The lifespan of a battery is measured in recharges. One recharge is a complete charge and discharge of a battery’s energy. A recharge doesn’t necessarily occur every time you plug in your notebook; many partial charges can add up to a single full recharge. Thanks to the breakthroughs of advanced chemistry and Adaptive Charging, the battery in the 13-, 15-, and 17-inch MacBook Pro can go through up to 1000 recharges before it reaches 80 percent of its original capacity — nearly three times the lifespan of typical notebook batteries

So if it drops down more, just call apple and get a new battery

I've got about 2 minutes to write this before I run out of battery ironically.

Anyway here are the readings I got.

Is this normal? How does this compare to everyone else?

I honestly wouldnt worry. Your MBP is still new, and the battery tends to flux in the begining a little. I wouldnt worry, to be honest

Battery capacity loss is not necessarily linear. Just because you lost 5% over the first ten cycles doesn't mean that you will lose another 5% over a subsequent period of ten more cycles. Have you calibrated the battery at all?
