I have a Macbook Pro 2015 retina and I wonder how the cycles of battery are calculated?

I have a Macbook Pro 2015 retina and I wonder how the cycles of battery are calculated?

If I load to 100% and then run it down on battery to 0% of course it counts as a battery cycle.

If I recharge to 90% and run up to 5% or 10%, which count as a battery sprays?     Between what % are there?

The reason I ask is that I try to keep the cumulative battery cycle count down.

Thank you

http://www.Apple.com/batteries/why-lithium-ion/

Whenever he finishes a full charge, it's a cycle.  If you charge 70% one day, then 30% another day, it's a cycle.

The Apple site, I posted above, it explains very clearly.

A cycle is counted when the battery has completed a 100% charge, not a discharge.

  • Fans of 0 RPM MacBook Pro 2015 retina

    I know that the new MacBook Pro 2015 idling retina have fans at 0 RPM.

    My MacBook pro retina early 2013 have fans idling about 1500 rpm, they are always on.

    Is it normal that my MacBook pro retina 15 inches?

    Thank you

    I don't know where you got information about a speed of 0 RPM. The good idle speed is 1500 rpm, and the fans are still running. This is what cools the machine. If you see a 0 RPM fan; then, there's a major hardware problem.

  • Chip and upgrade memory set on my great MacBook Pro 1.2 and want to download the latest OS to Snow Leopard. An Apple store guy did to his own personal machine, but the upgrade was a procedure in several steps. Help!

    I upgraded my MacBook Pro 1.5 with CT541631 CT2KIT12864AC667.000 2 GB UPGRADE for a APPLE MACBOOK PRO 2.16 GHZ INTEL CORE DUO (17-INCH) SYSTEM. I also added more memory. The Apple Store genius who did this on his own machine was on his own because Apple does not officially support the best MacBook Pro they never built and isn't there anymore to ask questions about the OS correct necessary updates. I think he said he had to go to Lion first and then upgrade to latest, although we both agreed that El Capitan was too buggy. Anyone know what I need to do to let the download procedure OS know that my ols is now a new machine?

    Where did you buy the RAM module?  If it was not directly a source of Apple, you did it sure it was for the year and the time of year of output of your model (i.e. mid-2006 MacBook Pro)?  To identify the age, go to this tip:

    http://discussions.Apple.com/docs/doc-6413

    Specs such as CT541631 CT2KIT12864AC667.000 are totally superfluous, unless they also indicate what year and the time of year, the model came out.

  • MacBook pro 2015 bootcamp error

    Hi all

    I have a MacBook pro, 2015, with 10 Windows boot camp on it (300 GB Mac, PC 200 GB)

    Windows and Mac have been working fine, until yesterday

    I tripped over the cable and disconnected the device (no problem, right?) but it off instantly, even if it had a decent amount of battery left and noticed a time of incredibly long boot, but Windows (which was what it was defined on) seemed fine, so I don't think about it

    But today I tried to use the side mac and I have serious problems

    -Incredible Lag (I pressed the H key, as a test and it came 2 minutes later)

    -Controls unresponsive (keys don't line up with what has been typed)

    -The mouse move (he jumped to a place randomly after trying to move)

    I did not connect, so I don't know anything about the problem

    If anyone has had this problem or knows something about it, I'd be delighted to hear your advice

    Thank you!

  • Retina, 15 inch, mid-2015 MacBook Pro number: flickering and the screen splitting

    Very happy user of a Macbook pro 2011, I thought about buying a new macbook pro 2015 15 ", 16 GB of ram, 512 GB of flash disk... I hope to have a new Mac, who suffer no lack of memory, and much faster.

    It's faster, for a week. Happy.

    Then, flicker from time to time, very fast, only 10 to 15 Hz strange flickering (turning slightly gray, at a frequency that really annoys the eyes).

    Then, split screen sequential, as in the video below.

  • 2015 the Macbook Pro 13 Retina El Capitan freezes randomly

    Hello

    I have a Macbook Pro 13 2015 with the Retina display. I plug in December. It has the most recent update of El Capitan (OSX 10.11.4). I have 91.8 GB of free space on the SSD drive. Around a month ago, freezes bad has started to happen. Frost occur generally when I'm browsing Safari, I do not know if it has nothing to do with YouTube videos, but maybe it's interesting to note that I usually have a tab open in Safari that's YouTube when it happens (but not always). Today, I already had 2 freezes, before one arrived, I read an article and it happened (a YouTube tab was open in Safari, however, the video did not play for the moment when frost arrived). The second time, watched a YouTube video, and freezing that happened when I clicked on the time bar to make the video at a specific time. Frost usually occurs when I interact with something like that, opening of a new video in YouTube (such as clicking a recommendation of video on the right panel), or interact with the video itself. Note, after I restarted the computer, the previous video is one which opens in Safari, if frost has occurred during playback of the video which freezes just after I started playing.

    However, it is not only Safari which can cause freezing. There was a specific case, when I looked at the images in the Photos app. There were many of them, and I pressed the arrow left and right to navigate through them. Then he suddenly freezes the whole system, couldn't get out of the application or anything. Such a freeze is really bad, I can't interact with the computer somehow, the mouse cursor freezes, time freezes in the status bar, no Cmd + space for Spotlight, no physical reaction buttons whatsoever. Only option is to wait a few minutes (in order to clearly identify the process before and during the system failure in the newspaper), and then press and hold the power button until the machine stops.

    I thought first of all it is a software problem, I did a complete reinstallation of the system (formatted the SSD drive, downloaded Yosemite, then upgraded to El Capitan, once again). I had 2 weeks of calm, but today it happened again (2 times so far). I share the newspaper of queries system log: all messages. The last frost that happened at 13:31, and I waited until 13:37 to restart the computer. If I'm not able to detect the problem, I think I'll try to return this product, because I think that it is unacceptable for a machine that costly to freeze the whole system and lost unsaved process in Word or whatever it is.

    Thank you for your help,

    Adam
