HT1446 Battery in Macbook Pro Retina

I have a new, barely used Macbook Pro retina.  Although I have barely used it the battery is now very low and although I have plugged it into the mains to recharge it, it will not start up and just shows the battery charging symbol.  Is this correct, or should I be able to use it whilst recharging.

You actually explained your problem well - it's just something that I've never seen nor heard of!
You can try both a SMC and a NVRAM reset -> Intel-based Macs: Resetting the System Management Controller (SMC) and About NVRAM and PRAM.
Although I'm not sure that will do anything - give it a try and call back.

  • MacBook Pro Retina 15 battery issue

    Hello,
    I'm having issue with my battery on MacBook Pro Retina 15 Mid 2012. System says Replace now but I have only 753 Cycle Counts.
    Run Hardware test and got the following error code: 4bat/1/40000000: 0x80c53f90
    Tried PRAM and SMC reset but nothing helps.
    It there any chance to fix this without replacing the battery?
    Regards.

    Not a chance: this is a goner. And don't take that "Replace now" message too lightly: a failing (swelling) battery can cause serious damage to your MBP.

  • Late 2013 macbook pro retina battery question

    I just bought the new macbook pro retina 2013 (first macbook!) I wanted to know what I can do to extend the life of the battery. Right know, I start charging the battery once it gets to about 60%. I keep the charger plugged in when im at home and left the battery discharge at uni. Would doing this having any advatange or disadvantage for the battery?
    Also once the battery reaches 100%, would it overcharge if it is kept plugged in? or would it just start to use the power from the adapter instead of the battery
    Anyother tips?
    Thanks

    Look at these links.  They will provide you with all the information you need regarding MBP
    batteries:

    csupinski is 100% correct, the OS will not allow the MBP battery to be overcharged.
    Ciao.

  • Battery replacement on MacBook Pro Retina Late 2013?

    Could you replace your batteries in a 13in MacBook Pro Retina Late 2013 yourself?
    If not, could Apple replace them at a fee or could I go to a third party shop?
    Also, how long or how much cycles does a battery last?
    I was planning to buy a macbook and was taking that into consideration.

  • Battery life in MacBook Pro Retina

    Hi guys,
    I bought last week a MacBook Pro Retina, 13inch, late 2012, and my battery life is nowhere near the 'expected'. Right now I'm at 57% with 3:14 but I know some people have 9hours on a full charge... It just seems weird. I already did a PRAM and SMC reset and my battery life didn't change at all. I read that it could be related to Maverick (which I installed recently) - could that be the cause?
    Also, I can't seem to understand what's the correct way to charge a MacBook. Should I charge it when it reaches 20% left (80% of use)? When should I stop charging - when it reaches 100% or less?
    Thank you
    (sorry if I do something wrong - I'm a newbie here)
    (happy new year!)

    Currently in some cases Mavericks is not reporting battery life as accurate in "time remaining" its being looked into.
    As for the battery:
    Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
    And best "tip" is if its near a socket,...plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of the time.
    http://www.apple.com/batteries/notebooks.html
    "Apple does not recommend leaving your portable plugged in all the time."
    General rule to remember of Lithium batteries is:
    Never drain them LOW  & dont always/often store them HIGH
    While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
    *A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge. 
    DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count.  *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                              (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
    *Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
    *However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
    Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                        This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
    LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
    A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
    Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
    The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
    Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
    Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
    From Apple on batteries:

    Storing your MacBook
    If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
    Considerations:
    Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
    In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
    Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
    Ultimately counting charge cycles is of little importance.  Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery. 
    Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
    Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
    Peace

  • Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?

    Is it possible to virtually bypass the battery on a macbook pro (retina 2014) and power the mac directly via AC power?
    E.g. Dell allows you to plug the laptop into AC power but prevent battery charging.
    Note: I do not want to physically remove the battery.
    If there isn't an option on Mac OS, is there anything I can download to bypass the battery when I want?

    Thanks for linking me! Wow I had no idea the clock speed would be cut so severely! What a bunch of rubbish, as if the AC won't provide enough power!
    I guess the only solution to my question would be an app which virtually disconnects the battery but tricks the mac into thinking the battery is still connected. I'm just surprised Apple haven't yet started to build prisons for the government - considering how well they lock up their software and hardware!

  • Battery Life on MacBook Pro Retina 15" purchased 1 week ago

    Hello Dear Community,
    About a month ago I purchased a MacBook Pro Retina 15" and after 1 week I noticed the battery was lasting for about 2-3 hours of web-browsing. It turned out the battery was defective and Apple sent me a new one.
    4 days ago I received the new laptop and I switched it on, did all the updates and installed Google Chrome.
    Here is my problem (or maybe I'm just being a bit paranoid):
    The battery was at 80% when I put on a movie. I was with standard out of the box settings, full brightness and volume at max. After the 2-hours movie battery was down do 21% which seemed a bit odd, but I thought it was expected with full brightness and volume.
    After that I was web-browsing ordering a pizza, went on facebook and watched 4 movie trailers which all and all took about 25 minutes maybe, but this got the battery down do 10%.
    Is this normal, because this is my first purchase of an apple product? Somehow losing 10% in 25 minutes seems a far cry from the promised 8 hours of web-browsing promised in the description.
    Very much appreciate any help with this!
    P.S: Apple Diagnostics found no issues.
    Regards,
    Incr3dulous

    I have 1 question though: Isn't it harmful for the battery to keep the MBP connected to AC with the charger at full battery?
    NO, NO NO!
    I keep my MBP connected to the charger most of the time.  Monthly I will use it with just the battery and connect the charger again when at the 40%± charge level.  That will keep the battery happy.
    P.S: How much do you usually get out of your MBP while browsing?
    Which one?  I have three of them.  The 2010 is the most energy efficient and I would expect it to last perhaps 6+ hours with very moderate use.  The 2006 has a smaller replaceable battery and I would expect 4.5 maximum at very moderate use.
    Watch a video and the times will be cut in half.

  • Poor battery life and high temperatures on MacBook Pro Retina 15"

    I'm having never-ending problems with poor battery life and high temperatures on a MacBook Pro Retina 15"
    I took it in for service and they told me it needed a new logic board and replaced it.  When I asked why they were vague about the reasons, they said "it just needed one, it failed some test".  I now have the computer back and it runs the same way it always did.  I bought this laptop because it was supposedly capable of high end video editing in 1080P (or so Apple's website claims) and also photo editing. 
    "The processor, graphics, all-flash architecture, memory, and display in the 15-inch MacBook Pro give you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,3 while the latest quad-core processors on the 15-inch MacBook Pro decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,1 you can even edit four streams of uncompressed 8-bit 1080p HD video, right from the internal storage on your 15-inch MacBook Pro with Retina display.4"
    However, when I'm just browsing the web and emailing it runs quite warm and battery life is quite poor.  Sometimes doing those same activities I would say it gets so warm it's almost uncomfortable to have on your lap and the fans are running fast enough to become noticably noisy.  I'm also driving only one screen at and a time and I heard that the MacBook Pro can supposedly do three screens.
    If actually try to do something like video editing with final cut pro the laptop gets really hot, the fans are on full blast and battery life drops to only an hour or two.  I think when I rendered just a 3 or 4 minute clip once I got less than hour of battery life.  I will have to time again.
    Anyway most people (including the sales guys) are telling me no way this is not normal.  When I play with demos in the store browsing the web they are not getting warm or hot to the touch.  My friend's 2013 MacBook Air is also NOT getting warm to the touch doing the same activities.
    I installed iStat Pro so I could check the temperature and fan speeds.  I'm seeing temperatures of 70+ on the GPU, 85+ on the GPU diode and 65+ on the CPU heatsink along with elvated fan speeds above 5K which becomes noticeably noisy.  I understand that might be normal for the most processor intensive tasks but it really doesn't seem right for just light web browsing and e-mailing.  (I also may have viber and skype open but that shouldn't matter).  CPU usage is usually running between 2-10% as this is all happening to.
    Furthermore, straight from the specs:
    Intel HD Graphics 4000
    NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and  automatic graphics switching
    I am assume "GPU" and "GPU diode" are temp measurements on the discrenete NVIDIA video card, especially since MacBook Airs from the same and newer generatio do not have this reading.  Since Apple Claims the graphics "automatically switches" it seems all the harder to believe the GPU is reaching 85+ when in theory it shouldn't even be activated.  I mean, shouldn't the INtel HD Graphics 4000 be capable of simple web browsing and e-mailing?  Especially with only one screen activated (be it it the internal or an external)?
    What should I do here?  When I asked the repair guys "OK well what is the normal operating temp range for the various sensors" they said "Sorry Apple doesn't provide that info". 

    Yes I have.
    Just web browsing and basically doing nothing I'm hear a lot of aduible fans, I'm getting 85C+ on GPU diode, 65+ on cpu heatsink.  I since installed anohter program that shows me not just the CPU heatsink but the cores and the cores are at 90C+.
    Seems like a lot of heat for doing nothing.  Not only that but I have these problems with no external monitor while on battery power too.
    I don't know what to do.  They already replaced the logic board.  Others seem to get advertised battery life out of Apple products and not have products that get **** near hot enough to burn you while just web browsing or watching a movie let alone advertised tasks like Photoshop and Final Cut Pro.

  • MacBook Pro Retina 15-inch battery life on Yosemite

    Has anyone noticed impact on the battery after upgrading to Yosemite? I found only one article online that talks about the impact. I followed the instructions but still the battery life did not improve. I'm running MacBook Pro Retina Late 2013, 15-inch, 2.6GHz Core i-7, 16GB RAM.
    I think that I should be getting more than 8h of life when fully charged.
    Link to article on iMore.com: http://www.imore.com/how-resolve-battery-life-troubles-your-retina-macbook-pro

    So here is an update: I've followed the article posted by OGELTHORPE (Thank you!). What I actually did is 1. Reset the SMC and 2. Reset the PRAM (MacBook Air SMC and PRAM reset).
    What I've seen so far: Once I did the reset, I would guess that the system needed to re-calcualte again the battery charge. Initially after I disconnected from power, it started with a measurement from under 3:30h. After 45 minutes running on battery it is showing again 8:45h remaining  @ 93% charge. What I noticed is that every time I put the laptop to sleep this repeats - starting with some low time measurement and slowly climbing. I think that this could be a bug in the software and the battery charge calculation method is somehow not working properly. I wonder after those resets if the OS needs to get into a couple of battery charge cycles and the battery is calibrated again?
    I don't recall having this issue with the last year's release of Mavericks.
    I hope someone from Apple sees this and address this with the next OS X update.

  • Macbook Pro retina display 13 inch stopped charging. Charger LED also not on while plugged in. The battery fully drained off but the system can detect the charger when it was switched on.

    Macbook Pro retina display 13 inch 2014 model stopped charging. Charger LED also not on while plugged in. The battery fully drained off so the system can not be started but the system can detect the charger when earlier it was switched on before draining off the charge. Charger type magsafe 60W.

    Once you have examined the power inlet on the computer for dirt, and made certain that the pins on the end of the MagSafe cord are free to move in and out to make contact, there is very little you can do yourself.
    You will need to visit your Apple Store (FREE with appointment) or your Apple-Authorized Service Provider (policy varies). They work on these all the time and have good expertise and lots of spare parts to try to determine the problem.

  • My Macbook pro retina battery is not working

    Hello everybody,
    I kinda need help, maybe somebody here can give me an advice. I kinda destroyed my Macbook pro retina with coffé My father spilled the coffé on the table and the coffé went exactly inside the laptop. It didnt work but after complete and careful cleaning it works. (except the battery) Battery is not working at all, but interesting is, that I still can see the percentage of charge of the batery.
    In the authorised czech service they told me that they need to replace the whole battery (with the skelet of the laptop) so it is very expensive. But I believe that there is maybe some other way? Anybody can help me?
    Thank you very much
    Jakub

    I forgot... The percentage of the charge of the battery is moving now it is 9% but before it was more... 10%,11% etc...

  • Is it possible to replace Macbook Pro Retina's battery?

    I have a Late 2012 macbook pro retina and after 2 years of working with it, it has a problem with battery. Yesterday it gave me a notification that the battery is in  "replace soon" condition. I would like to know if the battery replacement is possible on this model? Also i don't think we have a apple store in my country and I would like to know where can I take it, to solve this problem?

    The battery in the 2012 retina MBP is difficult to replace due to it being glued in place. See the iFixit teardown here: https://www.ifixit.com/Teardown/MacBook+Pro+15-Inch+Retina+Display+Mid+2012+Tear down/9462
    To have the battery replaced it really needs to be done by Apple either at a store or shipped back to them. Go here to see what your options are by country:

    There may be local non-Apple repair shops that will do this work, but you are taking your chances with them. Good luck!

  • MacBook Pro Retina 13" - Battery Issues after one week!

    Specs of Unit
    MacBook Pro retina 13" - bought literally one week ago
    Processor  2.8 GHz Intel Core i7
    Memory  16 GB 1600 MHz DDR3
    Graphics  Intel Iris 1024 MB
    OS X Version 10.9.2
    Problem - Okay so the estimated battery life of these babies are 9 hours approx.
    After a full charge I am getting an EST. time of about 4.30-5 hours battery life, bare in mind this is with NO programs running and NO background tasks sneakily rinsing the battery.
    Yes, I have tried reseting the system management.
    Yes, I have tried safe mode.
    Please help me, is the battery faulty and should I really go to mac store??
    Or is this  a software issue?
    Thanks

    Does switching off Wifi make a difference?
    In UK and USA (and quite a few other places) you have 14 days from purchase to get a refund or replacement - no questions asked.  If there is nothing running then this does sound to be depleting rather fast.  My late 2013 13" MBP retina gives me about 10 hours using Pages (several documents open) and e-mail only.
    Get a replacement and see if you get the same problem.

  • First cycle of MacBook pro retina of battery

    During the first charge of he MacBook pro retina, is it best to fully charge it and leave it on the plug?

    you can leave your Retina plugged in since once it's fully charged, it will stop charging......
    as with any macbook battery, it's best to use it plugged in when you're close to a power outlet and use it once in a while under it's own power and charge it back up once it's down to 75% to keep the battery in optimal condition...
    do not use your macbook under it's own power to 0%....it will do more harm than good to your battery...
    good luck and have fun with your new Retina..
