    Above; there's significance in, for example, use cases that involve loss of data.

    2016 rMB M7/256gb just purchased 18 days ago. 8 cycles on battery in that time. Battery Health now at 96%. Seems like it's dropping faster than one might expect. I'm watching it, of course, but not constantly.

    Just an FYI, those that purchased their Macs on a major CC like Visa or Discover have an extended warranty that doubles the manufacturer base warranty, up to 1 additional year. So my new Macbook warranty gets an extra year under the Visa extended warranty plan, 2 yrs warrantied! I didn't feel the need to pay for a 3 year extended warranty for my Macbook since I have 2 years covered.

    After noticing the battery degradation on my Early 2015 12" rMB last year, I bought AppleCare earlier this year, just before the 1 year warranty ran out. Glad I did, as the condition deteriorated to about 75% max charge before 350 cycles. So I decided to bring it to a repair shop.

    There wasn't much debate, they just switched the bottom plate, which included the glued-on battery. Attached is a Coconut Battery chart for reference. It shows the amount of degradation that was enough for AppleCare to fix it with no fuss. They had some proprietary Apple tests, and those too reported a problem.

    Hopefully this new battery can hold its condition better ... but if it doesn't, it'd better die before May 2018, because that's when my AppleCare runs out :)

    Thanks for the attachment.
    It looks as mine is taking the same route as yours.
    I am at 395 cycles, 20 months old, 81% health but last week I was as low as 65%. It has been fluctuating a lot (almost since day one) but not as much as the last couple of days.
    Did you get the notification on your screen to change the battery? Was this at 75%.
    I don't have Applecare but here in Norway we have very good warranties (they say). You may expect a battery to last 2 years at least.

    Hello everyone, I am a new owner of an (used) m5 2015. It is still downloading stuff from one driv which is obviously draining the battery. Estimate is around 3hours on a full charge. Is this normal with intense wifi usage like in this case?

    Which kind of real battery life should I expect once the setup process is complete?

    7-9 hours should be normal. 3 hours only when fully loading the cpu.

    Is there a special in-joke I am missing about the fact it's mirrored and turned sideways? :)

    (The battery probably did that.)

    Is this from a 2015 retina Macbook 12"?
    Anyhow: it is degrading fast, almost like a 2015 rMB.

    I thought only the rMB suffered from bad batteries, maybe because of the new terrace-design.
    Looks like yours isn't too good either.
    Perhaps you should have a look on the MBP forums if there are others with similar problems as you have.

    Hey guys. Ive been reading this thread b/c I am concerned about the battery capacity of my rMBP 2015 13". Is 10% of the design capacity being degraded within a year a reason to be concerned?

    rMBP 2015 13" base model. I got very upset when it dropped all the way to 99% for a moment :p

    I did get a message to service the battery, at or below 80 percent mark. It said so in the battery menu item too, but it disappeared after a reboot. Nevertheless, it was time for a change and luckily AppleCare people agreed.

    Nope, just me being stupid, I saw the iconic silhouette of Hitchcock before it was tipped. I got it the wrong way round, though:

    Apple batteries have a touch of Moe about them:

    Just keep watching it for a bit. Mine fell quite quickly early on and then stabilised at around 93-94% health. I'm now up to 100 charge cycles. From what people are saying its a common issue but a few have very rapid decline needed a change of battery.

    How much does it take to replace a new battery for MacBook 12"?
