Macbook pro 2011 battery question.

I got a macbook pro 2011, and I'm charging, draining and recharging the battery daily, i have the mac for almost 2 months and i have 75 cycles complete and the battery is on 92%, i want to know if I'm doing a good work charging the battery the way I'm doing it, or do i need to use another method, i work daily with this macbook pro in design, thanks in advance for the answer.

Honestly, I think you're cycling your battery a little too much. Apple recommends that you cycle your battery 2-3 times a week. So this means
2 months = 8 weeks
8 x 3 (cycles) = 24.
You should have roughly 24 cycles for the duration that you've had the computer, 75 is a little much for 2 months, don't you think?
I would strongly suggest cycling the battery only 2-3 times a week. Also, only do a FULL discharge every month. You should make the change NOW before you permanently damage your battery. I have the 2.3 2011 Hi res 15 inch MBP.

Macbook pro 2011 battery dropped to 30% after 300 cycles

Hello ,
I have a Macbook pro early 2011 and I have noticed that the battery suddenly is draining too fast , after installing battery health it seems that in 2 weeks the battery dropped from 86% to 30% and there is the service battery sign
Please help !
Charge Information:
Charge Remaining (mAh):    1696

Cycles mean almost NOTHING, its short term abuse that matters.
1. did you often drain the battery very low?
2. did you often /always have your macbook on charge,......or did you often / always BOTH have your macbook on charge AND in sleep mode?
3. did you often /always play realistic heavy graphics games ON battery on your notebook?
1 or 2 and 3 are harsh on the battery chemistry and therefore its longevity
all batteries are consumables meant to replaced either in their own "due time" or early due to abuse / misuse.
Proper understanding of a battery charge cycle
A charge cycle means using all of the battery’s power, whether that is at once, or over several shorter battery discharges and recharges.
Two examples for clarification:
As a first example, where one fully charged battery is discharged down to 10%, then fully recharged, then using 10% of that full charge, this counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
In the second example, where one fully charged battery is discharged down to 40%, then fully recharged, then using 40% of that full charge, this also counts as 1 cycle since the total of both discharges is 100% of a full charge of use.
While both examples are that of a single charge cycle, the first example is more aggressive against the lithium battery chemistry than is the second example. In short, collective overall gentle shallow or mid-range draining of your lithium battery is a better use condition than is the first example of deep-draining of the battery. While both are quantitatively identical as a single charging cycle, they are wholly different qualitatively on the battery chemistry, which is directly related to its ultimate longevity and health.
In short, it is the near and mid-term life of the battery as relates to its proper care (or lack thereof) that is to be looked after.
Priorities in order of decreasing importance for battery care are:
1. Avoiding deep discharges of the battery.
2. Avoiding having your battery constantly on charge or on charge and in sleep mode.
3. When playing graphics intense games, use your notebook plugged in when possible.
4. Reduction of battery cycles by plugging into power when on the go, or when accessible.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is vitally important on the wear and tear on your Macbook’s battery, much more so than is the counting of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will greatly hasten the lowering of maximum battery capacity.
Understand that a charge cycle is a general parameter of use, but is not directly related to the short-term or mid-term abuse of the battery, which can rapidly hasten a shorter lifespan, regardless of what the actual cycle count on the battery indicates.
Proper considerations for near-term care of the battery is of utmost importance. Abuse of the battery is entirely avoidable, long-term eventual old age deterioration of the battery is entirely unavoidable.
Apple’s adaptive charging system mitigates much potential for accidental battery misuse or abuse; however it is still readily possible to abuse the battery and thereby affect battery health.

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.

Macbook pro 2010 battery question

I have the mid 2010 macbook pro 15 and 17 inch. Was there a battery update for these machines?

Hi Drew,
All updates should be listed i Software Update in the Apple menu. I recommend you run whatever is listed there.

Macbook Pro 2011 battery not charging error code

My Macbook Pro just turned 1 year old and the battery might be defective or dead ( Warranty just passed by ) it originally cam with Snow Leopard but I WEB upgraded to Lion (which was far from being easy ... had alot of crashes and hanging happening)
I have the now infamous battery not charging problem. The OSX status bar shows the battery icon with a 'X' meaning no battery. I think the MacBook is not charging the battery because OSX doesn't see a battery.
Today I just noticed that (IMPORTANT) with the power adapter connected, pressing the battery power level button displays a 5 blinks code. Otherwise with power adaptor not connected, the battery seems even too weak to light up even a single LED".
Even though I do a proper shutdown, it is to note that the MacBook Pro starts right away when I plug the power adaptor. I starts right away without me even pressing the power button.
Yerterday I really though the MacBook Pro was not going to work anymore, it kept abruptly shuting down again and again. I couldn't do any of the work I was supposed to.
I did PRAM and SMC resets and eventually I was able to startup the MacBook Pro and do some work but the battery still remains unavailable.
I have 2 of the same 85 Watt charger ( the first one being from a previous MacBook Pro 2008 --- which is waiting to get a repair ) and both performs the same: not charging.
Maybe the battery discharged beyond the point it can be seen my the MacBook Pro and OSX. Just like car battery, if it get discharges way too much, you won't even see the nominal voltage on the terminals even without any load.
EDIT: just noticed that even though it looks like no battery OSX reports that power source IS BATTERY (in the OSX status top bar )

It's like mpg for a car. It depends upon how you drive, the weather, the terrain. "7 hours" doesn't mean anything. Your mileage will vary. If I am not doing anything I see 13 hours. As soon as I start surfing or watching a video it changes. Stop obsessing.

17" Macbook Pro (2011) battery drains or not charging while using intensive CPU

My brand new 17" MBP (August 2011) has a serious problem: Despite the AC adaptor is plugged in, the battery starts to drain (or is unable to charge if it is lower than 95%) when I ran intensive tasks (like rendering with After FX, convert videos with Compressor or start to play a videogame). I tested it and it happens under Mac OS X and Windows 7 (BootCamp).
I readed some user have the same problem with 15" & 17" MBP 2011 models. But I haven't found any solution.
Anyone knows if this is a hardware or software failure? Do I need to ask Apple for a new machine?
Any help will be welcome. Thanks.

Thanks Retired Engineer, but I don't think it's normal. Well, maybe it is "normal" (or by definition: common) in the 2011 MBP models, but it doesn't means that there is a problem with its design or hardware.
I have an "old" 15" MBP, which I bought in 2007, and since then it never happened to me that the computer is draining or unable to charge the battery while heavy processor intensive processes. I used the exact same softwares and processes in my new 2011 17" MBP, and then is when I detected the problem.
I read on some forums that this is a common issue with 2011 models. I don't know if Apple has an official answer about this or if there is a solution or workaround. Maybe they could simply shipped this machines with a more powerful AC adapter, able to deliver more than 85W, which seems to be not enough.
I will make further investigation about this, because I think it is a serious problem when it is presented in a computer labeled as "Pro", which I understand is designed to be under heavy usage.

MacBook Pro 2011 Battery Re-Charging Issue

Hey everyone, I discovered a problem on my 2011 MBP 17" which I was told that "it's perfectly normal' and I want to see if you guys can reproduce it on your new 2011 models as well (please indicate your screen size).
In summary, I noticed that depending on CPU usage, the battery reacharge time will greatly fluctuate to the point where the laptop just stops charging the battery. I noticed the giant fluctuations in time when I booted one of my VMs which used up like 15-20% overall cpu usage. I was at 5% battery life and the computer was plugged in recharging and the battery indicator all of the sudden went from somewhere around 2.5 hours recharge time to 10 hours to 15 then 20 hours. Then at some point the magsafe light went green and the battery indicator showed 'Not Charging'.
I thought that I may have a bad MagSafe so I tried the one from my 2009 MBP (both are the 85W version) and bam same problem. I figured that this may be due to a design flaw where the power unit cannot supply enough tower to feed a CPU that's being somewhat taxed (i'm talking about 25-50% usuage) and recharge a battery.
Here is a simple way to try to reproduce the problem:
1. Let you battery drain to about 80% or less.
2. Close all open programs.
3. Change your battery indicator icon in the menu bar to display the info as 'Time'.
4. Plug in your MagSafe and let the recharge time in the battery indicator calculate and stabilize (give it about 2 mins to get a stable time value).
5. Open up safari and go to Hulu and play any TV show to drive up your cpu usage.
6. Then open Terminal and type the command 'yes' (without the quotes) and hit enter. The 'yes' command basically causes an infinite loop of the letter 'y' to be display in the terminal window which also taxes your CPU in addition to the video playing in Hulu.
7. Now watch the battery indicator's recharge time value and you should notice that it'll start going up significantly in time and at some point it'll say 'Recalculating' and eventually it'll give up and say 'Not Charging'. I have a 2009 MBP 17" C2D 2.66GHz, and although the recharge time goes up by 20-30% in the exact same test, it at least still charges the battery.
I was able to reproduce this at the apple store on a 17" 2011 model as well but I'm curious if this also happens on the 15 and 13 inch models. I was told by the engineering team on the phone that this is 'perfectly normal'. I guess it falls in the category of malfunctions as designed...

TheRosta, jkirker and zapatillo: Everything you report is normal. Under heavy load, more power is delivered to the CPU/GPU/other hardware and less to the battery charging circuitry. Under very heavy load, all power goes to the processors and none to the battery, and under extreme loads, power is drawn from the battery to supplement what is provided by the AC adapter. All of this is by design.
You might well ask why Apple didn't just provide a more powerful AC adapter. I don't know Apple's reason(s), of course, but one possible explanation is that the machine couldn't dissipate the additional heat that would be generated by feeding 20, 30 or 50 more watts into it. If that's the case, then maybe the present 85W adapter is the best compromise Apple could devise between providing sufficient power and managing heat effectively, without completely redesigning and enlarging the MBP case to accommodate bigger fans and heat sinks and more air circulation space.

Hello
I have a macbook pro 2011 13" that came with OS Lion (integrated not on a disk). I recently bought OS Mountain Lion of the app store and it is working fine. However I was a bit dissapointed in the battery so I decided to try and downgrade and completely failed, I froze the computer and when I restarted it it did not work. I went into recovery system and erased my disk and all that and went to re-download my OS. I was expecting to get the option to re-download Lion but instead I could only re-download Mountain Lion.
My question is since my computer originally came with Lion can I reset my computer so I get OS Lion back instead of OS Mountain Lion?
Thanks for any help. Any answer will be appreciated even if it is saying it is not possible.

Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
    1.    Select Disk Utility from the main menu and click on the Continue button.
    2.    After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
    3.    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    4.    Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Kappy, a pretty wonderful and very knowledgeable man, has tip for that which I have copied and pasted above

Macbook Pro 2011 charging behaving weird. Charges and stops repeatedly and takes very long. Help?

So a few weeks ago my MacBook Pro 2011 started having charging problems. I would use it normally. Then plug it in to charge anywhere between 5-20 percent like I've been doing for the past year that I've had it (since August 2011). Anyway, what happens now is that it charges but extremely slowly - at least 4 hours to fully charge as opposed to the 1 1/2 to 2 hours that it used to take. Also, it seems to be draining a lot quicker than it used to while only browsing the internet. Furthermore, while charging, the battery meter goes from the percent its charged to to "not charging" back and forth. What's going on? Is there a problem with my battery, my computer, or the magsafe charger? [please refer to the pictures below to get a better understanding of my problem - these pictures were taken over a 2 hour time period - a time period that usually is enough to charge my computer] - if you'll notice, in the first two pictures, the percent barely went up by 10 in a half hour period:

try doing a SMC RESET and see if that sorts it out for you.
if doesn't work - better take it to Apple and have them look at it before something else goes wrong...
good luck - hope you get it sorted out..

Macbook Pro 2011 - Apple It's time

Hi,
So I'm the owner of a new second-hand 17" Macbook, for years I've dreamed of getting one of these and today was finally the day it happened. Specs are
Macbook Pro 2011 Late
i7 2.4Ghz
6770m
8gb RAM
At first the laptop booted up fine so I decided to do what any new proud macbook owner would do, show it of at work. During the course of the day I experienced intermittent freezing issues and eventually a blue screen of death. I thought to myself that I must of brought a dud and immediately went to contact the person I brought it of for a refund. Being a genuine trader he was more than happy to oblige and give me a full refund. Frustratingly this macbook had already grown on me enough to the point where I was determined to research into solution. Initially I suspected a HDD fault so I went to attempt a apple internet recovery, all that solved was my blue screen of death and changed it to a grey screen of death. Digging deeper it was clear from countless others in my situation that the issue was being caused by the GPU.
Now I'm no apple genius but I have enough of a computer technical background to know when something has not been done right. Now clearly apple has done wrong in the manufacturing process of GPU soldering and thermal paste application. This issue is nowhere relevant to software except for the point in which the system switches from the integrated to the faulty discrete GPU like it's suppose to in high-intensive tasks. Having this macbook for only a day and some determined researching its pretty simple to join the dots. The soldering process and material they used was doomed to fail from the start, eventually all 2011 models with discrete GPU's will burn out, it just depends on how well their owners have taken care of them. In regards to the thermal paste application you will be able to see from my images the kind of care and pride apples has undertaken in applying it. There was more around the CPU & GPU than there was on itself, that's like having a peanut butter and jelly sandwich with most of the peanut butter and jelly smeared around the plate. Considering this laptop would of cost close to 4500NZ back in the day I can't imagine what other original 2011 Macbook owners are feeling.
What makes it worse is that apple techies you go to will say a full logic board replacement will be needed from your own pocket when your macbook was already doomed, isn't that a way to rub further salt into the wounds Apple. Opening up my macbook it was obvious to see that the logic board inside was not the original and sometime during it's lifetime it too had a full logic board replacement. However I can't say if it was for the same reasons. Regardless it's obvious that replacing the logic board does not solve the issue and wastes everybody's time and money.
Apple, these macs require two things.
-A solder repair for the GPU
-A re-application of thermal paste
It's really not that much to ask considering the worth of these laptops, also wouldn't you rather have these leaving a legacy of the ultimate desktop replacement than apples shameful ticking time bomb?
I'm typing this of the very macbook having these issues so for anyone who wants a temporary fix please refer to the free gfxCardStatus software which allows you to force integrated graphics only. For now it's stable but dreadfully hinders the potential this beast was made for.
"Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations."

In hopes that apple does not remove this post.

There is excessive swapping of data between physical memory and virtual memory.
That can happen for two reasons:
You have a long-running process with a memory leak (i.e., a bug), or
You don't have enough memory installed for your usage pattern.
Tracking down a memory leak can be difficult, and it may come down to a process of elimination.
In the Activity Monitor application, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select
View ▹ Columns ▹ Real Memory
from the menu bar.
If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more real memory over time without ever releasing it. Here is an example of how it's done.
The process named "Safari Web Content" renders web pages for Safari and other applications. It uses a lot of memory and may leak if certain Safari extensions or third-party web plugins are installed. Consider it a prime suspect.
If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.
The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command:
sudo leaks -nocontext -nostacks process | grep total
where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details.

Step 4: Install the Boot Camp Drivers for Windows
After installing Windows, install Mac-specific drivers and other software for Windows using your Mac OS X installation disc. The Mac OS X disc installs drivers to support Mac components, including AirPort,built-in iSight camera, the Apple Remote, the trackpad on a portable Mac, and thefunction keys on an Apple keyboard.
The Mac OS X disc also installs the Boot Camp control panel for Windows and theApple Boot Camp system tray item.
To install the Boot Camp drivers:
1 Eject the Windows installation disc.
2 Insert the Mac OS X disc. If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
3 Follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.
Windows that appear only briefly during the installation don’t require your input.
If nothing appears to be happening, there may be a hidden window that you mustrespond to. Check the taskbar and look behind open windows.
Important: Do not click the Cancel button in any of the installer dialogs.
4 After your computer restarts, follow the instructions in the Found New Hardware Wizard to update your software drivers (Windows XP only).
5 Follow the instructions for any other wizards that appear.
6 Check for updated Boot Camp drivers by using Apple Software Update or going to www.apple.com/support/bootcamp.
If You Have Problems Installing the Device Drivers
If it appears that the Boot Camp drivers weren’t successfully installed, try repairing them.
To repair Boot Camp drivers:
1 Start up your computer in Windows.
2 Insert your Mac OS X installation disc.
3 If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
4 Click Repair and follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.
If you need to reinstall specific drivers, you can install one driver at a time. For example,if your built-in iSight camera isn’t working, you can reinstall just the iSight driver.
Individual drivers are in the Drivers folder on the Mac OS X installation disc.

selling macbook Pro 2011. It came with Lion, I upgraded to mountain Lion and Mavericks. Can license be transfer to new owner? how?

Good question now that Mavericks is free to all.
It used to be - and is probably still the case - that to comply with the license you should erase and re-install the OS that came pre-installed on the Mac when new. If there were restore disks they needed to be passed on with the Mac.
I'm happy to be corrected on this by someone who's more au fait with the legalese, but an upgraded OS is tied to an AppleID whereas the original OS is tied to the computer, not an AppleID.
My guess is, that if you launched the Recovery HD, erased the drive using Disk Utility and re-installed the OS, Lion would be installed.
Be interesting to see what others say.
