    I have a 15" MBP with 94 cycles and 88% battery health. From what I'm told this is lower than it should be...should i contact apple and try to get a replacement battery?

    80% and 300 cycles is the cutoff so no, not until it gets below 80%.

    Thanks! I was wondering about this, and this is a good guideline.

    Just curious, when does the meter for a battery "cycle" start? What I mean is, how low does it go before it is considered a "cycle"? If I go to 35-40% and plug in, is that considered a cycle?

    Just wondering.

    Thanks!

    Apple says that "Using and recharging 100% of battery capacity equals one full charge cycle."

    Oh ok, so just to clarify...if it gets below 80% in under 300 cycles then i'm eligible for a replacement? :cool:
