Is this battery degradation normal for a retina MacBook Pro?

[rawCpoppa]

Pic taken off coconut battery so I don't know how accurate it is. I remember reading a couple years ago that the battery in the MacBook Pro would last for longer cycles than other brands so after a year I'm surprised it's down to 92% already.

It's a 15 inch retina MacBook Pro.

Anyone with insight?

That doesn't seem too far off. Apple's claim is 80% capacity after 1000 cycles:

I think it's fairly normal for a battery to drop the first few % points fairly quickly and then level off for a while. Just keep an eye on it I guess. Do you have AppleCare?

Yes that's the claim I read about a few years ago. Thing is 92% after 120 cycles compared to 80% after 1000. The trend seems to be faster than the claims? Or is degradation not linear?

Nope I don't have apple care. In live outside the US so figured I would get a run around if I needed to use it.

I hope you are right about the faster degradation early on in the laptop's life. Thanks.

You tried doing a smc pram reset? My 17 days retina was showing me 92% health when it was 43 cycles did the reset and it slowly went back to 100%.

Btw my macbook pro non retina has 300 charge cycles and has 95% health.

I would anyways suggest you keep monitoring it and if it goes below 80% before 1000 cycles have apple look at it.

mine is still at like 8800mah so over design capacity but its only 3 months old
