Apple Macbook short battery life problems

If you’ve noticed that your Macbook or Macbook Pro purchased in 2006 or 2007 is losing its battery life at an alarming rate, you’re not alone. Apple has had a very large batch of Sony lithium-ion polymer batteries for their laptops that are losing their maximum charge capacity very quickly.

System Profiler - Power

If you’ve noticed that your 4 hour battery life dropping to just over 2 hours recently, check your System Profiler for some information about your laptop battery power system.

System Profile can be found in Finder => Applications => Utilities => System Profiler.

Once you have System Profiler open, find Power underneath Hardware. Click on that item and on the right side of the window, scroll down until you find the Battery Information heading.

The three values we’re interested in are Full charge capacity (mAh), Cycle count, and Battery health.

A normal reading for Full charge capacity is about 5200-5400 mAh (milliamp hours). That translates into just over 4 hours battery life. Cycle count is how many times the battery has been used to capacity and recharged. Battery health is a word describing overall life expectancy and condition of the battery.

Remember that Apple has published on its Apple Support site that their laptop batteries are designed to hold 80% of its original charge capacity after 300 cycles (see the footnotes).

Doing the math, that means the Full charge capacity should be around 4160 to 4320 mAh after 300 cycles. If your Macbook battery is failing, like mine, it should read less than 3250 mAh, with a Health of “Fair” after far less than 300 cycles.

But, don’t despair. With that juicy price paid for the best laptop available on the market comes pretty good customer service. Bring your Macbook into an authorized service center, an Apple flagship store, or call up Apple support hotline and explain the situation. Also note that there are several support forum threads on about users describing the same situation and what Apple has done for them:

For Macbook users experience battery life problems as described above the warranty coverage is being extended to two years, so even if your Macbook is out of warranty, your battery may still be in warranty.

I currently have a battery being sent to me and we’ll see how things turn out.

Good luck.

    Where does it say that Apple has extended warranty coverage for 2 years? I just called them and they said mine is not covered now since I bought it a little over 1 year ago. They wanted to know where I read that there was a 2 year warranty and if it is says that anywhere on the apple website.

    I just found the link on the Apple website you were looking for. (I’m having the same problem, but mine is under warranty, luckily.)

    “For MacBook and MacBook Pro systems with Intel Core Duo processors, this program extends repair coverage on the battery for up to two years from the date of purchase of the computer.”

    THANK YOU for posting this article and Clay, thank YOU for the link!

    My battery has mAh of 1359 after only 34 cycles. I purchased in Jan 2007 – so perfectly in their window.

    First agent I talked to said I wasn’t eligible b/c of my serial number. After he repeated that to me three times, I had him read the post Clay links to. And then I asked to be transferred to a product specialist. She verified my battery numbers again as well as the software update I had. Then she approved the battery replacement.

    So, if you call and legitimately fit the criteria – just push and don’t take no for an answer.

    Thanks again!

    I just tried getting a new battery for my MacBook Pro. The battery program ended in June 2008. I am not a very happy customer and will be telling everyone about this. I am so not happy with Apple right now. I depend on this computer for my day to day business. They suck.

  8. Carlton8429 Avatar

    My request also rejected by Apple today. Battery 22 months old, lasts 12-20mins before stopping without warning. Holds 1692mAh after 297 cycles (so much for 80% of original charge after 300 cycles!). Extremely poor considering my friend with 4 year old clapped out Dell still gets over an hour from his battery

    Apple said battery is a consumable item and worn out, not covered by their 2year extended warranty on Sony batteries, despite fitting their criteria of a faulty battery. It was purchased 27 March 2007, in the timeframe of the recall.

    I have spent over $10,000 on Apple products in last 5yrs including imac 24″,imac 17″, MacbookPro 15″, and 2 mac mini’s, not to mention Airport expresses and extremes, and software upgrades.

    Extremely angry at Apple stance, poor handling of issue despite fitting all criteria on their service website. All goodwill destroyed, I won’t ever sing their praise again, all for the cost of a minor part. Right now, they do suck!

    I got my macbook november 2008. lately my battery life has been not as great as it used to be, almost 5 hours to 2 and a bit. Is this normal? I’m at 4810 mAp after 53 cycles.

    I would really appreciate any help on this. I’m new to mac and I love it, but this battery thing is a little disconcerting!

  11. Sarah Avatar

    I also tried to call in. It took a LOT of persuading to get them to transfer me to a battery specialist, but they did. Basically, their battery program ONLY covers batteries UP to 300 cycles, not beyond. So if you haven’t reached 300 yet and you’re under 80%, call NOW.

  12. Ken Avatar

    That 300 cycles limit is bad news for me. I’m at 492 cycles (whatever that is), and I got my MBP October 2007. I must say, this is my first Mac and if this is what I’m to expect from Apple, I’m very disappointed. This computer was my switch from PCs. I’ve never had a battery problem with any of my PCs, not even when they were 4 years old!. Apple knows they have a problem with batteries and they aren’t going to back it!? So I barely get a year and a half before they kick me to the curb on this!? Nice.

    I’ve had my Macbook Pro since April 2007 and almost always use it with the charger plugged in. Why? No idea, just habit I suppose.

    The other night I was going to use it without the charger and started it up. I checked on how long the battery life was without the charger and it said 3.5 hours. That seemed like more than enough time to pay a few bills and send a couple of emails. Within ten minutes, my computer shut off.

    Any ideas of what caused this? What I can do to prevent it? I’m supposed to take minutes at a meeting tonight and would prefer to take them on my laptop, so I’m hoping it will be an easy fix.

    Hi. Thanks for sharing that piece of info.

    This is my macbook’s battery info.

    Full charge capacity (mAh): 4199
    Health Information:
    Cycle count: 35
    Condition: Good

    Above you said:
    Doing the math, that means the Full charge capacity should be around 4160 to 4320 mAh after 300 cycles. If your Macbook battery is failing, like mine, it should read less than 3250 mAh, with a Health of โ€œFairโ€ after far less than 300 cycles.

    That means my battery is not in a good condition considering that I’m only at cycle 35. Should I use my warranty and get a replacement? Btw, I just bought my macbook March 16th 2009!

    Nurmisliana, your battery is fine. For the new Macbooks, a bad battery will have the condition listed as: Check Battery.

    Try to completely discharge and recharge the battery. The full charge capacity will be reset.

    I have had my macbook 6 weeks and after 11 cycles the full capacity was 4202. I calibrated as per mac instructions and the full capacity didn’t change so thinking that my full capacity should be about 5200-5400 I visited the local Genius bar. He stated that the full capacity is around 4500 but replaced my battery. When I checked system profiler the full capacity rating was 4230. He said this is ok.

    What is it 5200 or 4200? Do I believe him or do I insist on a battery which shows 5200. Is my computer giving the incorrect info? Or am I misunderstanding something about the full capacity rating?

  22. Chad Avatar

    My battery says (Check Battery). I have had my Macbook Pro for just 14 months. The worst part is Apple sent me an email to add apple care. I followed the link and purchased it. Once I received the package a few days later I tried to activate it but the website would not let me. FInally apple sent me a refund for the Apple Care. Should not have let me purchase it in the first place..

    Now my battery is dead. I called apple and they tell me that they cannot replace it. They said I would have to purchase a new one (very disappointed). Then the rep goes on to tell me that if I purchase it from him over the phone I would only get a 3 month warranty but if I purchase it online or from the Apple store I would get a full year warranty… Nice job guys.. Screw the customer that calls in. At least my rep was good enough to tell me.

    This is my first Apple computer. I bought it because Microsoft had made me so mad with their early releases of software. Well now Apple is in the same boat. I now own 2 IPhones, 1 MacBook Pro, 1 Mini Mac and 3 Ipods.

    I will never purchase another Apple Product again. I will stick with MS… at least if I am going to purchase a disposable computer I can pay a lot less for it.

    My battery seems to be in fair shape but a full charge certainly does ‘t last as long as it used to, roughly 3hours tops. The fan seems to run a lot more than it used to which may be the reason but I haven’t found the cause yet (yes it’s summer but it aint that much hotter!). Anyway.. stats as follows if it’s of any use to anyone. PS it’s a bobby basic white intel Macbook 2.5 years old.

    Hi” Folk’s
    I phoned apple 28/7/09 to report battery problem on my 2007 MacBook Pro,
    Charge Max 643 Charge Remaining 627 Cycle 276.
    However after taking my Seri / No, I was told that it was a consumable item and
    it was so to speak fair wear & tear and that they would not replace the battery.
    I then went online and found this web site and am i glad i did armed with CLAY &
    Kate’s comments I phoned apple again spoke to a nice chap and asked this time
    to speak to his boss who is now sending me a new battery.
    So David Kim if you read this give apple another call.

    Ps” MANY THANK’S to Clay & Kate for your comments

    bought a macbook for my daughter late December 2007 and now the battery will not re-charge. Spoke with Apple representative, who stated that he is the ultimate authority on replacement. He replied that my battery does not fit the prescibed period of purchase. Missed it by 3 months.
    Will NEVER purchase an APPLE computer and will let everyone interested in purchasing an Apple NOT TO do so. Word of mouth is the way to let people know.
    Thanks Apple for disappointing the public.

    GO buy Dell. They have better products.

    Called this morning with the same issue. I’m getting a new battery

    The trick: Extended AppleCare coverage. So it can pay off to have an extended warranty. well, sort of. It was 300 bucks and the battery is only 129.

    Before you buy a new battery or despair and leave apple land for what appear to be greener pastures (remember viruses folks? and customer service can suck all over-idiots and jerks are employed by every company in every corner of the computing world, so please don’t think you’ll be escaping any of that mess by leaving apple), CALIBRATE YOUR BATTERY!!!!! You can find instructions on Apple’s website, or right here:

    1. Run your battery down to 0%, making sure (of course) to back everything up first.

    2. Let your mac fall into a nice peaceful coma for at least 5 hours. (You can also just turn it off at this point if it makes you feel better.)

    3. After AT LEAST 5 hours, plug your mac back in and let it COMPLETELY recharge before you turn it on again.

    4. Go back into your system profiler and check your battery health, and you may well be pleasantly surprised at how nicely your battery has bounced back from the brink of death.

    5. If you re-calibrate monthly, as Apple suggests, it’s likely that it will live up to Apple’s promises.

    I re-calibrated after my battery started telling me that it was not functioning properly and needed to be checked by The Experts. As a Do-It-Yourself kinda gal (I also recently replaced the optical drive in my macbook-piece of cake people), wasn’t about to do that. So re-calibrated, pushed the silver disc to reset/recheck the charge, and viola! Happy, healthy battery.

    Best of luck to everyone, and please try everything you can before replacing or heading off to pay for tech support.

    Many thanks for all of your comments.

    In November, the battery on my 16-month old MacBook Pro just sort of fell off the cliff. As recently as August, it showed a full charge capacity of 5300 mAh, but now was at 2187 mAh. Cycle count was at 30.

    I first tried taking the steps suggested above. However, there was no improvement.

    So I then took the computer to a local newly-opened Apple store. (Important hint: make an appointment before visiting if you intend to actually speak to someone).

    They ran a diagnostic, and it indicated the battery was bad. Even though the computer was 157 days out of warranty and I had not purchased extended coverage, they replaced the battery. No fuss, no argument.

    From my point of view, a happy ending.

    I have a similar problem with my battery on my MacBook Pro. I purchased it in Jan 2007 and started noticing serious decrease in battery longevity after six months or so. Unfortunately, I just put up with it. Now I get about 8 minutes of time off it before it just goes dead and shuts down the computer without warning. Strangely, it indicates that it still has 89% capacity left just before it shuts off. I tried calling Apple support (still have a month left on my AppleCare warranty) and they told me that it’s to be expected with a 3-yar old laptop. I’m very disappointed. I could see if it only had an hour or so of capacity left, but 8 minutes? My boyfriend’s 8-year old Dell laptop still gets about an hour and a half to two hours (depending on what he’s doing on it). And to think I spent literally 3 times what he did for his ($1900 for the MacBook Pro, plus $270 for the AppleCare). Never again. From now on it’s pc laptops running Linux (Ubuntu most likely) for me. I feel burned.

    Here’s my experience at Apple Store in the San Fernando Valley.

    Made an appointment at Genius Bar. Told them about the problem and that my research indicated that Apple knew about it and was providing some kind of warranty but I wasn’t sure if I qualified for it. My cycles were at 450+ and I’m 8 months out of warranty. He gives me the fairly hard company line. I tell him I tried very hard to avoid having to make an appointment for something that any floor tech could have told me by looking up the serial number. He offers to sell me a discounted 90 day warranty, which I tell him I appreciate but I want to know if Apple has fixed the “problem” (he tells me Apple hasn’t officially recognized that there is a “problem”) so that this battery won’t just conk out after a few months. He gets hushed and quietly sets me up with a free 90 day warranty battery.

    I think this is how it should be done. The Apple Rep tried to shake me off, but I was persistent and ultimately I’m very pleased with the way the rep handled it. Apple can’t just go around handing out free batteries to everyone who asks, but I’m glad the reps have some discretion to make the right thing happen when it should.

    I just had the opposite experience from Johnny and I must admit it was quite pleasant.

    I made an appointment at the Genius Bar and added a short comment to the why are you coming in section describing the battery, the 35 cycles on it and that it would only hold 1560mAh after only 1 year. The battery was just over a year old but the MBP that I have is more than 2 years old, so both were over warranty.

    When I talked to the rep, I pulled out the MBP and just told him ‘It’s the dreaded Sony battery issue’ while I also pulled out 6 pages of Coconut Battery and System Profiler information and also another 12 pages of posts from this and other website. Fully prepared to show him all the details.

    Without even looking (he saw I had all the docs) he just plugged in his iPod and Option-Booted a diagnostic from it. After 2 minutes, he turned the MBP over, pulled out the battery, went into the cabinet behind him and pulled out a box ( there were lots of them ) of a non-OEM packaged battery. Popped it in, pressed the battery check button, smiled at me and just handed me the Mac back and a single paper to sign for the battery replacement.

    He was very careful to not fall into any of my trap questions like ‘How many of these do you replace’ or ‘I’ve read it may be a battery issue or a Snow Leopard and SMC firmware issue’. He was carefully schooled in not admitting any liability or blaming anything.

    I personally think, after reading the good and bad comments on this thread that Apple has a list of serials of batteries that they will replace with no question. Others, they stick to the party line.

    Well, I’m glad I was on the right list. This battery reads as being manufactured by SMP. My old one read as Sony. Hope this lasts more than 35 cycles!

    My battery on my 2007 Macbook Pro has just expanded and bulged down underneath (so much so that it stopped the tracker pad working and made the computer rock on a hard surface). It has been replaced under my Applecare policy. I didn’t realise there was a problem with this age of battery – they just said that they occasionally get one which does this.

  40. everart Avatar

    I also had a battery on my MacBook Pro go rogue and bulge. I was 5 months out of warranty, but when I took it to the Apple Store and they saw the problem, they quickly replaced it at no charge.

    For the people who say “never again” when they have a problem, I say that after 10 Macs in twenty years, 6 of which are still running–you still get what you pay for. Sometimes you do have to be persistent and do your homework, but Apple has always come through for me.

    Note that this comment is the most important on this page:

    I read an above post by someone who was not eligible for a new battery for free, but got one anyways after being persistent with the Genius.

    If your battery dies or just needs replacement, and your outside your warranty, you obviously have no reason to get a battery for free. However, if you go and meet with a Genius, not a floor rep, and complain (find any reason to complain whether it be you are dissatisfied or complaining that PC batteries last longer) and claim that you are unsatisfied and will no longer buy apple, you will be given a new battery for free. This sounds like I just made this up or something, but Apple has a “Whining policy”. They can’t give everyone that walks in a battery for free, only customers who are unsatisfied. 9/10 people will say “OK than how much is the new battery”, but every customer here and then will be satisfied, and in fear of losing that customer for life (potentially thousands in profit), they will just give you anew battery. Just try it. Today, I got my second replacement battery for my Macbook white for free. At first the Genius said 130 dollars for a new one, it’s wear and tear. After complaining for 5 min, he said let me see what I can do, came back with a new battery gave me the box, and said I’m making an exception. This is a typical whining policy that many companies utilize.

    I purchased my Macbook on Black Friday of 2008 for about $1,000 plus the Applecare warrenty for another couple hundred dollars and a wireless printer for $118. The printer needs software; So it doesn’t work wireless. Plus within one year, my powercord stopped working. Apple replaced it, but didn’t check the computer to see if it was a computer issue (as I suggested). A couple months later, the battery went out! So I bought a new battery for about $129. Now two months later, my second powercord went out! THIS IS CRAZY! This product is too expensive to have so many problems! I don’t think its all of Apple’s products, but MY UNIT SEEMS FAULTY! I keep telling them this. Their customer service can be great, but sometimes they’re headstrong. It’s a machine! One may be faulty! It happens! I know because mine seems faulty. There’s nothing wrong with my plugs. I don’t use it enough to burn it out. Could it be my computer?

    I am having the same problems with my battery. I bought my mac laptop last year around June and now my battery life as been dropping. I checked my power using the system profiler and my cycle count is at 302 and it has a full charge capacity of 1932 (mAh). Does anyone know what I should do or if it is maybe my computer not the actual battery?

    I just wanted to thank yo for this writing! The part about the footnote on the applecare site: “Apple has published on its Apple Support site that their laptop batteries are designed to hold 80% of its original charge capacity after 300 cycles”… saved me having to buy a new battery.

    I called several apple months ago before I had reached 300 cycles (now I’m at 337), and I got brushed off, saying they wouldn’t help because battery depletion is normal. This time I called and quoted that footnote, and they are now replacing my battery free of charge.

    I own a MacBook Pro and the battery life and I was only able to get just a few hours per charge and that is if I was lucky. I’m a professional photographer so this just didn’t cut it for me so my eventual solution was to get an external laptop battery from Novuscell Batteries. So far, no regrets because I’m now getting an extra 12+ hours of battery runtime per charge on my MBP.

    on January i bought a new battery for my mbp, so i was so happy… 3 days ago die…
    Because i live in mexico and i went to the mexican apple store they told me that is out of warranty whattttt well if you buy it in mexico they give you only 3 months is so so unfair the true is that i dont know what to do even when the prices here in mexico are more expensive i pay almost 200 dlls for it. I think apple have to make fair policies in all the countries, i don’t know what to do…

    i do love apple i have a powerbook since 11 years and is still a live and the battery that has it when i get it still is working .. i dont know why does apple is not paying attention to the quality anymore.
    they should because the people who bought apple things before get in love of it so quick …but now that love is changing in hate.

    Does somebody need a mbp battery to make some art i do have twoooooooooooo

    geez people… read the comments! What a bunch of babies. There are some very helpful comments here– especially the one about re-calibrating your battery. Go back and read the comments! Yes, all of them. Also, turn off bluetooth and airport when you’re not using them to save juice. And check the Apple page for more tips:
