That's why my macbook pro battery drains much more quickly than in the past?

The life of the battery of my (end 2013) 13 "MacBook Pro (OS 10.10.5) decreased a lot, very quickly, in the past months. There are 390/100 amount remaining fresh and the State of the battery is 'normal '. I do not leave the appliance plugged, "over" charge for long periods of time. I drained the battery fully before recharging for a full charge. Although wifi is usually left on; Bluetooth is usually disabled. I am running the same programs I ran for years.

Meanwhile, the battery for this machine seems to have declined precipitously.

I hope that others can offer advice on how to evaluate what is happening and what (if any) can do to improve the life of the battery.

I drained the battery fully before recharging for a full charge

This isn't a recommended service action. It can damage the battery if done repeatedly. I charge when mine gets below 20%.

You can't damage the battery by leaving the charger plugged in for long periods. There is overload protection very intelligent integrated in the battery and power on the computer systems.

A reduction of RUNTIME† is often a software problem. This Apple article is excellent to determine if this is the case and how to address the issue:

Apps can affect the performance of Mac, battery, temperature and fan activity - Apple Support

† - the battery life is time, usually years, before the batery fails and must be replaced; battery life is how many hours the pathophysiological dough power the computer before requiring a recharge.

    Hi, the trackpad batteries are unloaded much faster than in the past.  I reload and replace them and they quickly weaken.   What needs to be replaced, the batteries or the charger.   Tried to look on the apple website to purchase and find nothing (there must be there somewhere).  Thank you.

    They may well be replaced.   Take a look at this document.    iFixit are well known in these columns.

  • Why my Macbook Pro boot used place in any mode but the comments?

    My Macbook Pro almost 5 years, worked very well, then the beech ball began to come a lot and programs would take forever to load. I tried to stop him to restart in diagnostic mode, but it would not closed and just hung up for about an hour.  I hit the power button to force a power down and when I went to turn it on again, it does not start in safe mode or diagnosis.  He goes to the login screen and gives me the choice of my log in or invited, but starts if I select my journal going through the motions leading to the top of the load bar, but before he gets to the end, she stops.  I can start in guest mode and access the internet, but I can't do anything from there.  If I click on the Apple, it gives me the opportunity to go to the startup disk, and when I click it, it asks which drive I use, (only one option, HARD drive), but when I select it, there is nothing there.

    I can't really afford a new Macbook for now, and until the last few days it works very well, so I prefer to get it fixed to the top if I can, so any help is appreciated.

    See you soon,.

    Hey there,

    I see your message that you are unable to connect to your user account, even in safe mode.  I would like that you try to start your computer in OS X Recovery and then try to repair your hard drive.  If the problem persists after that, you can reinstall OS X.

    To start your computer from recovery, restart your Mac and press the command and R keys at startup.

    Hold these buttons until the Apple logo appears. After your computer has finished starting upward, you should see a desk with an OS X menu bar and window OS X Utilities with the above options. If you see a login window or your own office instead of the utility window, it is possible that you do not press command + R early enough. Restart your computer and try again.

    Choose the option you want to use from the utility window or in the Utilities menu.

    OS X: on OS X Recovery

    Take care.

  • MacBook Pro battery issues

    MacBook Pro (2013) are stops with 35% left in the battery. Why is that happening and how can I make it stop? In addition, it seems that since the download and installation of the recent update of El Capitan, the battery runs more quickly. I hope there is an easy reset for all this!

  • Retina of MacBook Pro battery SUPER fast, please help?

    I have a MacBook Pro (retina, 13 inches, beginning 2013) and recently the fan was spinning VERY fast and I did reset smc, cleared up a bit on my laptop and now its good but the battery has fallen like a madman. It was 50% in the evening and I put standby, but I wake up and its 0%. In the sound class always 98-40. Help, please?

    Why not leave it plugged all night and plug during breakfast or during the course, it is not necessary?

    Load circuits will prevent price hard.  My MBP stays connected when you do not move, but used up to 30% of battery once a month if not more often.

    Running to death just shortens life considerably and it looks that it has been executed to death several times for you.  And there must be some periods during the day to get in 30 minutes about charging during the day.

  • MacBook Pro battery

    Hi all

    I have a serious problem with my Macbook Pro bought in February 2011

    In recent weeks, the battery was not load correctly, or the laptop came into fashion 'sleep' to 40% or 50%, so I had to use my phone still plugged in, when it's on. Lately, on the screen with users, I saw that said 91 percent, but when I was on my account, he said "do not load" Even worse if I unplugged the laptop charger closes with 91%.

    The cycles of the battery were approximately 225, so I do not understand why in the world my battery had problems.

    Last night when I was about to use the laptop, I noticed, that it was not closed correctly, one side had one large gap than the other and when I opened it, noticed that the trackpad was not in its normal position, as if someone was the extraction of it. So I figure the battery itself expanded during the night or during the last 2-3 nights.

    I read in the older messages that I have to take the laptop to an Apple Store, and they'll replace it for free. Unfortunately I live in a country where there is only retail stores, and I doubt that they are replacing, even less free.

    My question is, is there a specific battery, I could buy to replace it myself? A battery for a 13 "MacBook Pro 2011? Is this a problem on 2011 model? It's a bit disappointing because I did not give the laptop of its total use, to die so soon.

    I take the battery before it expands more would you recommend?

    Thanks in advance for any response.

  • Is my Macbook Pro battery defective?

    I got my Macbook Pro since 2012.  For some time on the marketing of the battery, it started sometimes and then turns off for no apparent reason.  It of today and has not responded to the power switch, finally raise a screen indicating that I had to go to food.  What I've done and the laptop booted normally.  As the indicator of battery at the top of the screen showed more than 40% charged that I wonder if my battery can develop a fault.  Does anyone have a similar experience?

  • What's wrong with my Macbook Pro battery?

    So this is sort of related to the question I asked yesterday

    Do not charge the MacBook Pro battery

    But fundamentally there is no light on my charger and the battery bar was at 2% for a whole day saying is "do not load" I have even if it is turned off and disconnected last night and it didn't lose charge. It is under the battery bar

    What could be going on with her? Battery health status shows 'Normal' and 'Remaining Charge (mAh)' keep ranging from 85 to 87 and he is down to 75 last night and now it is back to 85. I get a new charger because the one I have is a no knockoff Apple and I think he could have done something to my Macbook, but there is a problem with the battery itself too?

    When you get a real Apple charger that works, then you can start the battery, if problem if it does not work properly. In the meantime, it would be useless to pursue this avenue.

    Ciao.

  • My macbook pro battery will not hold a charge

    My macbook pro battery will not hold a charge. I took in an Apple reseller and claimed him install a new battery. He said that my battery was still good. I asked him to install a new battery just to have a brand new machine. With the new battery installed, the computer still will not hold a charge for very long. I got the Apple dealer and he ran several tests without conclusive results. I always have a laptop that will not hold a charge and must be connected to use for any period of time. Can anyone offer a solution? Thank you.

    Hello! I've got CS3 Design Standard - real records and certificate of software license. It was installed on my laptop that crashed and could not be uninstalled. I have now installed it on my new MacBook Pro, but can't get it registered with the serial number. Is it because it has not been uninstalled on the previous laptop? What should I do now? THX!

    Maybe this can help someone else...  I had to simply properly uninstall CS3 and reinstall again after that.  I think what he sort!  I also remember having a similar problem with the Mac at work a couple of years back.  Not sure if it is the same for CS5/CS6.  Here is a link on how to properly uninstall CS3 on Windows XP, Windows Vista and Mac OS.  I'm on OS X 10.9.2 but it works beautifully.  Remove from Creative Suite 3 and CS3 products
