    Hey guys so my 13inch 2015 RMBP is just 5months old and the battery has 41 cycles to it but it only retains 96% of its capacity and when compared to coconut battery chart, it shows that the battery is below average.

    Is this normal or should I be worried?

    Probably not they do drift up and down and there is no real entirely accurate way of measuring them.

    If you feel it's not lasting as long as it should take it to apple and get them to check the battery if it's lasting as it usually does then I'd not worry about it.

    I think you should get rid of coconut battery and any other monitoring software.

    All they do is make you obsess over something you have absolutely no control over, taking away from the enjoyment of your machine.

    Battery health fluctuates constantly, due to temperature, charging state and a whole lot of other variables. Take it with a grain of salt.

    TL;DR, everything's fine, delete coconut battery.

    This right here.

    Just use the computer. If the battery drops below 80%, it'll give you a warning and you can take it in to Apple.

    Those things are inaccurate, don't worry. Mine came with 105%, then dropped to 98%, then back to 103%. Count the hours, not the percentage.

    It is entirely an estimate, as others have said, and it often goes up as well as down. What matters is the long term trend, which you won't see for at least a year of use.

    Ignore the readings and just use your computer.

    Have the same macbook, 151 load cycles in and 97,1%. But it was fluctuating quite a bit, i remember it was down to like 93% or whatever one time
