The first unibody 17" Macs with built in batteries came out about a year and ten months ago. Apple promised us the battery life would not start to degrade for at least three years, and that we would get 1000 charge cycles out of them.

For those who bought those machines when they came out, how is your battery doing? Have you noticed reduced performance? I so love the battery performance of my new 15" Unibody MBP but hope it'll be nearly as good a few years down the line!

apple did not promise the 3 years thing. it said 1000 charges is about 3 times more durable than other companies' battery (usual life is about 300 charges), if i remember correctly.

it also depends on how you use your laptop. i have a friend who left his mbp on sleep fully charged but not plugged in and went Europe for 1 month. When he came back, the battery lost about 1/3 of its total capacity. I don't know why but it happened.

It was stated in Macworld 2009 Keynote. Business rule #1: Never promise your customers anything. Apple learned that when the promised Mac buyers in the mid-90's free phone tech support for life, got sued for stopping it, then forced to resume it. And they are still providing it, I like to call and chat with them sometimes.
