    I bought this Macbook Pro 13" about 10 days ago. This isn't THAT bad is it?

    I kinda calculated I'll be hitting 300 cycles in about 30 weeks. :eek:

    It's normal for your battery health to fluctuate up and down over time. This should answer most, if not all, of your battery questions:

    Alright, just a bit worried over how soon I'll deplete the battery over time, how much is a Macbook Pro 13" from Apple? All I'm seeing is the 15" model batteries.

    Thats fine , Mine does the same exact thing. one day it has 102% health ,, next day it's 98% and so on



    Try to drain it then fully charge it , health will go higher

    It's not a straight-line depletion, so you can't accurately estimate how far it will deplete in any particular timeframe. For example, it may drop 5-10% over the first 3-6 months, but then only drop another 1% over the next year. It fluctuates up and down.

    Calibrate it? Alright. Usually I get it down to 5% until I charge it anyways. :)

    The newer MBPs with built-in batteries do not require calibration. Read the Battery FAQ. It really will answer most or all of your questions.

    Okay. I was reading about the battery replacement, the 13" Macbook Pros can take the same 15" battery as advertised?

    The batteries are built-in and must be replaced by Apple. This, too, is explained in the FAQ.
