Hello, i have a wonderfully useless question here for those more well aquainted with Macs: My Macbook Air 11" was built in January of this year, so about six months old, and is at 137 battery cycles. BatteryHealth and CoconutBattery both put the remaining battery health around 90% (original capacity, 4680 mAh, current capacity, 4285 mAh). Is this normal for a computer this age? Honestly it's not a big deal 'cause i get several hours out of it with normal use, but with a computer this new, i had to check. I DO understand that battery health degrades fairly rapidly when compared with the rest of the hardware. Also, at what point is a battery considered consumed? Thanks a lot for the help!

MacBook Air, OS X Mountain Lion (10.8.4)
