    Hello all,
    I've just bought my first macbook pro exactly 10 days ago. It's the standard 13" 2.9Ghz i7 macbook pro. I've used it only for 6 or 7 times till now (average of not more than half an hour each time), cause I'm busy these days and I don't have time to transfer and organise all of my files from my old pc. However I've downloaded an app called coconutBattery, It shows that the age of my mac is 4 weeks and the current capacity is 5599 mAh and the design capacity is 5770 which is 97%. Is that normal for a 10 days macbook? or let's say 4 weeks according to the coconutBattery app? I've googled the app and I've seen some people with 93% for a 1 year mac.

    I copied this from the app, incase it helps you guys figure this out:
    Current capacity: 5599mAh
    Design capacity: 5770mAh
    Mac model: MacBookPro9,2
    Age of your Mac: 4 weeks
    Battery load cycle: 2
    battery temperature: 30.2 C
    Battery power usage: 8.8 Watt

    Thanks in advance and I really appreciate your help.

    Battery capacity fluctuates, especially when above 90%. My 2009 MBP jumped from 97 % to 92 % within days, then back to 95 %, now after three years and a measly 400+ cycles it jumps between 91 % and 94%. No need to worry unless the battery capacity goes below 80 %.

    There's no need to download utilities. All you need is already there. Macs manage batteries very well.

    Your job is to use it & enjoy it. Evaluating anything when it's so new is a waste of your time.

    Celebrate the fact you have, what many people wish they did.

    It's going to fluctuate as mentioned and applications that report capacity aren't always 100% accurate. Using coconutBattery, if you check it a few days from now it may report 98% or even higher instead of the 97% it's displaying right now. It's nothing to worry about, the battery should last you a long time unless it is faulty and you will know if it's faulty or not.

    Mine was 97% right out of the box. I just figured anything close to 100% was normal.

    Thank you guys for the help.

    I think I'm just being paranoid. My previous Iphone was dead after 10 days of buying it. And the problem that where I live, there are no apple stores. So I had to wait for 4 months till a friend went to Canada and replaced it. Shipping it to the States or Canada would cost not less than 300$ and when they ship it back, I can't claim it unless I pay customs and tax.

    Thanks again :)
