    I have a Mid 2015 Macbook Pro, i have always paid attention to battery conditioning. Decided to use coconut battery on the recommendation of someone on here. Does this look "good"? Much appreciated.

    For the age? Definitely. My Macbook Air - I also pay attention to battery conditioning and care (I'm what some would call OCD). I have a 2015-04-13 Macbook Air 11 - 106 cycles and 96.1% of design capacity left. It does spend a lot of time plugged in. And I'm happy with what I've gotten (considering the age).

    83.7% capacity after 1444 charges cycles on my mid-2011 MBP. The interesting thing is the capacity dropped to this level after about 3yrs and has stayed there for another 4 years.

    Just use it, worry less.

    You've lost 2% of the design capacity in 2 years, thats excellent just don't worry about it.

    I still have a 2014 MBP that's been used heavily and I have never considered the battery, last time I bothered to look the capacity was in the mid to low nineties.

    Is this a humblebrag thread? I've run across new computers with worse batteries than this.

    Yes, it's fantastic.

    Complete noob here. I have an incoming mbp coming Wednesday. Any tips on keeping the battery ship shape? I had no idea you shouldn’t leave it plugged in, thanks for that!

    That is wrong you can leave it plugged in fine, there is very little you can do to extend battery life these days the battery controllers are sophisticated and work well. Do use it on battery every now and then try not to let it discharge to 0. That’s about it, your battery will last 4-6 years and need replacing there is not a lot you can do about that as age is far more important than anything else.

    Can I tag onto this question? I've been getting "service battery" for a couple of weeks. Does it have anything to do with running it to sleep a lot last month? I tried recalibrating twice, though I think it shouldn't be necessary.
    I feel a bit reassured by the replies above saying "just keep using it." Does that apply here too?

    If you're getting "Service Battery", take it into Apple and they will get it replaced, no questions asked, provided you have AppleCare on it.

    It's past Applecare. "Battery service" is C$259; I assume that's a new battery?

    Yes, they will swap out the old battery for a new one.

    Yeah that’s a new battery and whole top cas as well. Just a quick note when a battery gets to that level it’s chances of swelling, causing internal damage and being a fire risk go up a lot so it’s usually best to get them replaced.

    Did this happen because I let it run down so many times last month? Why does it need replacing with <600 cycles?
    At this point it still lasts about 2.5 hours on battery.

    Is the risk the same with my normal use, which is plugged in?

    No it’s coming up six years old it’s just worn out, time is always the most important factor in battery death I always bank on 4-6 years for a MacBook battery life.

    There's 33 cycles on that almost 2 year old battery. It barely gets used. At that rate, does battery conditioning even matter? More of an OCD thing at that point.

    I bought it refurb; the battery is 3 years old, 2015. Does that change things?

    Yeah I word have expected it to do a little better than that be honest! If you bought an Apple refurb and AppleCare and it’s still within the AppleCare they will replace it for free.

    No. It DOES NOT apply to you.

    Your battery is "wearing down" from usage.
    Time to get it replaced.

    Having written that, Samuelsan's advice in reply 21 above applies, too.

    Now it seems to be okay. The "Service Battery" warning is gone. Do I cancel my Genius Bar appointment for Monday?
