    Poor battery life - Reset the PMU

    • Written by from Aurora

    My MacBook Pro battery never seemed to provide very good battery life. It also ran very hot. Within one year it barely held a charge. I bought a new battery recently and when I installed it it barely lasted 1.5 hours! Frustrated, I called technical support where they recommended that I reset the "PMU". Following directions, I reset it and "voila" over 4 hours of battery life! I then tried the old "dead" battery and it ran for over an hour! My MacBook Pro always ran very hot and now I know why. Must have been churning away on the battery. Could this be your problem?

    Here's how to reset the PMU. (BTW.. there are some repercussions from the reset. Search the site for details) 1. Shut down your computer -2. remove the battery - 3. unplug the AC - 4. then hold the "power on" button down for 10 seconds. That's it! Then reassemble and reboot. You should be good to go.

    2 years 1 hour.

    • Written by from baltimore

    Yup. It does not matter how often you cycle the battery it dies after 2 years. This is my third mac and my second bad battery situation. Right now I am very lucky if I get 1 hour of battery life out of it. Apple makes too much money to allow this to continue.

    Horrendous Battery!

    • Written by from Miami

    Battery life decreased 15% the first month, and now it is signaling for me to purchase another one? I hardly even use this computer, I've had it for only one year. Extremely disappointed, PC's hardly have this issue.

    Swollen battery

    • Written by from Edmundston

    I have 5 macs in my house, and this is the first time I'm having problems with a Mac... Everything was OK with my Mac Book Pro battery, but suddenly, it swelled up really bad, and it is completely not usable anymore!!! Since my AppleCare Plan expired a few months ago, I have to buy another battery, and I think it is frustrating, because Apple knows that they have mojor problems with those batteries!!! The replacement battery should be free of charge!

    Less than 2 year life

    • Written by from Oakland

    I've taken good care of this battery, conditioned it regualary etc. and after having it for about a year and a half it gets only about 20-30 min. of life. They have about a 2 year life before they're next to useless.

    I bought my MacBook Pro in August of '06. A little while ago, my battery life started dropping almost exponentially.

    Apparently, what apple does not tell you when you buy the computer or the battery is that you can expect a maximum of 300 cycles. Now, if you're a student like me, you use your laptop AS A LAPTOP almost every day. Or if you were someone who travels for work and can't often get corded power for your computer.

    Basically, if you use your laptop AS A BATTERY-POWERED LAPTOP regularly? Expect a MAXIMUM of a year for your laptop to be usable as such.

    Basically, I have the most expensive semi-portable desktop on the planet now. I'm not too pleased. After 300 cycles it is not covered by your apple care plan, so don't even bother calling them, except to see if there MIGHT have been a recall.

    If you use your laptop regularly, make sure you can afford a new battery at LEAST once per year. If you're like me and can't afford this, then don't bother buying the laptop.

    If anyone had told me about this issue, I would have bought a mac desktop and bought a cheap laptop elsewhere, saving me money.

    The weak link

    • Written by from Carmel

    Original battery (from 2006) lasted until Fall of 2009. I then was forced to get a replacement battery, yet it has only lasted a little over one year.

    THE PROBLEM: These are lithium-ion batteries. Apple needs to go with the better (albeit heavier) Nickel-metal hydride battery (NiMH).

    One year of use, no matter how many "cycles" is ridiculous. For such a great product as the MacBook Pro, it should have a battery that meets or exceeds the competition.

    It simply does not.

    Max life for you MBP 15

    • Written by from WESTON

    To keep your battery life at its best, charged it to the fullest and used it until your computer runs on reserver battery when there is no ac plug-in around, then charged it to the fullest. If you're going to used the battery make sure you drain it then charged it back. If you're around ac plug-in, take the battery out of your MBP, THEN PLUG IN THE AC ADAPTOR, therefore the batter is out of the picture, and your battery will perform at its best with very low cycle. IT WORKS! There is no need to used the battery or leaving it attached to your computer when you are around the ac plug-in. Never charged it @90,80,70,60,50,40,30,20,10 % Always charged it @ 0%. Follow these steps and you will be happy with your battery and your MacbookPro.

    Do a better job!

    • Written by from Saskatoon

    I love the computer, but this is my second battery in less than three years. I think Apple gets a very decent price for its product so it should back up its award winning computers and software with a battery that lasts...either that or provide a replacement battery at reasonable price. Enough said.

    Love Apple, Hate the Batteries

    • Written by from Brooklyn

    I am a Apple user/lover - desktop, laptop, iPhone, etc... but the batteries for the MacBook Pro are simply awful. I literally get about a year 1/2 out of each one I'm forced to buy. I have to order another one today, because my batter dies now at 50%.

    Cycling your battery.

    • Written by from Carpinteria

    All of you who are complaining about Apple solving this horrible problem, need to learn how to use a laptop. Cycle your battery! There are no problems with apple batteries (save the random broken one). I bought my macbook pro almost 2 years ago and use it everyday. When I got it, it had a battery life of about 4.5 hours. It now has a battery life of 2 hours...2 years later. This is normal for laptop batteries, and better than most other companies out there.
    All you need to do is make sure to unplug your machine from the ac jack when using it in your home. Run the battery all the way down to zero, then let it recharge (you can use it while it recharges)! If you do this your battery will keep its "memory". Don't just leave it plugged in all the time!!!

    Poor battery performance

    • Written by from Bloomington

    Like most of the other reviews, my MacBook Pro is only about 14 months old and the battery calculates that it has 1:33 left, but it quits in 15 minutes and does it without even a low battery warning. Disappointing.

    Not a good battery AT ALL for the price.

    • Written by from Chestermere

    I bought a new battery for my MacBookPro after having it one year. I have had this battery now just over a year with, so far, a total of 203 charge cycles. I used to get 2.5 to 3 hours out of it, movie watching included, but now I'm lucky to get just about an hour from it.
    Granted 'Mack' is my good friend, 'he' never leaves my side, but I feel with the superior products Apple is putting out on the market at these prices they need to do better with the life duration of this particular battery. One year is not good enough. If this must be the case then put the price down, otherwise I feel bad to even think that they may be trying to milk us for the small accessories that we have no choice to replace.

    Very disappointing!

    • Written by from Marietta

    I bought my MacBook Pro 1-1/2 years ago and the battery won't hold a charge. It shows it's 100% charged and then quits without warning. Unacceptable, in my opinion! Such a great computer but with a serious drawback. Now that I'm researching the problem, I am learning about cycling the battery. Why wasn't this more clearly communicated when I purchased and set up my laptop? I expect better from Apple.

    Annoying battery performance

    • Written by from Amman

    I purchased my macbook pro in 2007, original battery worked for 3 years. Since then, I am buying a new battery every 11m regardless of the care to use as instructed!! The battery stops suddenly (the current one I have dropped this week from 73% capacity to 16%!) and now refusing to charge).

    It is not only annoying and expensive for an under-perfoming battery. It is also hard to purchase a battery for the older models out of the US!! Apple should definitely invest more in its hardware's performance and availability!

    Come on Apple & Steve Jobs

    • Written by from Melbourne

    On to my third battery like so many others that have complained... IS ANYONE AT APPLE LISTENING? Have been a loyal Apple purchaser since 1982 -- worse product ever owned. Hope the internal batteries fair better. Apple leadership would be wise to fix this & rebate to its customers. APPLE -- LET US ALL KNOW YOU ARE LISTENING & HAVE A FIX!!!

    Quo Vadis Apple?

    • Written by from Rödermark

    this product is a desaster! I would have given no star instead of one if I could. Like already described by hundreds...battery lived for about 15 month. After that the light at mag safe started to do weired things, switched between red and green and no colour at all. Battery shows 40% charge and two minutes later the computer shuts off with no warning. And the whole thing gets very hot! In my eyes clearly a manufacturing error. I complained - but no help at all. So Apple, what are you going to do?

    1st battery was fine, last 4 replacements have failed

    • Written by from Lakeland

    Battery that came with the computer lasted 450 cycles. I was ok with that. Bought a replacement and it failed within 100 cycles, next one was less than 100 cycles, My current battery says replace now and it is at 36 cycles. There is obviously a quality control issue here that should be addressed. For $129 the battery should last a while.

    For all those reading bad reviews

    • Written by from Manahawkin

    Look people, if you have a 15 inch Macbook Pro like I have, you came to this page and see a sea of bad reviews from people who have batteries die after a few months. Here's my deal. I, like many "five-star raters" here have owned a Mac for 5 years and my battery has lasted that long only to recently show signs of dying. I have 61 cycles left on my old battery and it still lasts 3 hours if I let it drain close to 10%. This is while running graphic design programs, internet, and communicating with fellow workers. My point is if you have a 15 inch you have no choice, you either buy from Apple or a cruddy one from Amazon or eBay and end up with a meltdown. Price wasn't an issue for me, I like a product sold by people I know will let me return it if there is any problem, fast shipping, and patient customer support. So do not be put off by bad ratings, I can't tell you those individuals mistreated their batteries, and I don't know what I'm doing right, but I can assure you as someone who used to hate Macs, I trust this product.

    I bought an iBook G4 in December '04 which is still on battery # 1, yet bought this MacBook Pro in March '07 and have a dead battery. I used both laptops in the same fashion. What's up with this?? Come on, Apple, your great OS and software are only going to last you so long before people get frustrated with this built in obsolescence and switch back!!
