okay so usually i charge my macbook pro while im using it and sometimes when it gets to 100% i unplug it and just use it on that charge for a minute or so. then i plug it back in and it gets to 99% and says fully charged. how can i get it to 100%? does it matter? thanx!


MacBook Pro, OS X Mountain Lion (10.8.2)

    Well think of it as a fraction 100.0000/100 whe fully charged - when you are fully charged its 100%, but if you remove the plug, obviously immediately it starts to eat up your battery, so drops from 100/100 to 99.9999999/100, and average it out to a whole integer gives you 99%

     

    (dot notation I use is for decimals)

    thanks Setrino but what i was wondering is if i plug it back in at 99%, shouldn't it go back up to 100 soon?

    also thanks stedman1 that link helped i think. so basically its no big deal its pretty much fully charged anway, right? thats what i got out of the link correct me if im wrong.

    Why would you unplug for just a minute or so?  For what purpose?  If you want it to go back to 100% wait till it gets to at least 50%.

    Yeah Why in the world are you disconnecting the charger when it reaches 100%. Stop doing that and it will stay at 100% for a while.

    okay thanks for your comments Shootist007 and CMCSK! I usually unplug my computer because earlier I had some issues with how long the battery lasts at 100% and to check how much time it has on it i have to unplug it otherwise it will say fully charged or the time until charged. if you know what i mean. if there's a way to do that without unplugging your laptop i would love to hear it.

    ps. shootist007 you couldve been a little nicer in your response i know i am clueless with computers but still...

    thats okay tho no worries
