    I closed the lid on my 2009 Macbook Pro with Mountain Lion and it went in to standby. Ususally (under Lion and Snow Lepeard) this was not a problem I could open the lid days later and not notice a discharge at all. However on this occasion I left it Sunday Morning 19th August 57% charge, as I opened the lid today and the Macbook woke, it loaded the dektop image and I could see 57% battery remaining, however as soon as the desktop became active the battery showed 3%, it lost over half it's charge in 4 days asleep.

     

    I also have a rMBP and I haven't dared take it off charge in case I ruin the battery. I did notice however that the charge cycles increase if I just unplug it for a moment to move to a different location which is a bit annoying!

    hi, on putting 10.8.1 in, and turning on sync features ive disabled tostop my air frying, and battery draining (turned on sync in outlook, calender, turned on notifications) my air is back to frying, and battery has gone from 30% at 6am to 19% at 6.12 am, 15% at 6.17am.

     

    Apple care Sydney have been great, as has Larry from Apple California, but the bigget issue is Apple Inc

     

    Apple advertised Mountain Lion as the best computing experience yet, with enhanced battery life. Knowing there were battery issues with ML, Apple decided not to warn customers like me and thousands of others that some portable users report battery problems.

     

    The only good thing about 10.8.1 is that Apple do not- repeat do not say that this update is going to fix battery drain issues. For once Apple are being honest.

     

    adi190, dodsworthchris, complain to Apple, get a case opened, consider some of the fixes in these pages, or get your ML money back and go back to Lion...

     

    I'm going to Apple Sydney today to go back to Lion, until Apple Inc decides not to treat us like mugs.

    I am using a MacBook Air 13" (1.8 Ghz Intel Core 2 Duo, with 2GB RAM).

    Just updated to 10.8.1.   The battery problem is NOT solved.

     

    It says 2:42 hrs remaining and 95% of battery.

    I am going to find a solution how to get back to 10.7 although I believe I have to format my system, go back to 10.6 (that is on my rescue usb drive) and spend some hours re-installing my software.

    I guess I will wait for some days until I do this and I hope that Apple will make an official announcement about this issue. Apple is not behaving correctly towards its consumers given that they are aware of the problem.

     

    But after all it's my mistake: never update to an OS unless people test it for some months.

    Note that I switched just 6 months ago to Mac os after almost 20 yrs with windows and my first impression of mac os (10.7) was GREAT. However 10.8 is really disappointing.

    rBMP Base here.

     

    Upgraded from Lion to ML.

     

    Now, after 10.8.1 I have this doing nothing but Safari:

    A simple calculus shows that I should expect 3 hours with full charge?

     

    OH come on Apple! I am on the lowest + 1 setting brightness!

     

    Seriously! That's my first mac and I went from bliss to nightmare! You know, I'm this close to buy a Carbon X1! THIS CLOSE ]..[

    Chiming in here as a computer engineer who has been following this thread and afflicted by the battery life issue..

     

    I upgraded to 10.8.1 and reset SMC / PRAM. I saw no increase in battery life. For example, I left a few applications open (Chrome, iTunes, iMessage, Mail) and put the computer to sleep. I came back four hours later and the battery had lost 4% of it's charge.

     

    This is still no comparison to Lion - where I could only lose a percent overnight (8 hours).


    TLDR: I am backing up my data and doing a clean install of Lion. I did not spend $3000 on a laptop to have up to 4 hours of battery life.

    ... Time to some positive vibes:

     

    It seems that mine MBP from mid 2011 (15') got slightly better after upgrade: the first 5 minutes after upgrading to 10.8.1 (the safe mag was removed / the battery was fully charged at start) showed the "usual" 41/2 hours and the percentage fell rapidly during & after start to  about 95%. After closing a couple of unused programs (mainly office stuff) it slowly corrected to over 7 hours (charged at 95%) within 15 minutes of (only) webbrowsing. Notification centre was off (I do not normally use it) / bluetooth was off, wifi on and screen dimmed to lowest confy brightness - 2 dots).

     

    Hope that 10.8.1 solved it for me.

    I think we are witnessing Apples biggest flop in the history - have they now had their peak?

     

    I switched to Apple 3 years ago and have loved my Macbook Pros, iPhones, iPads, iPods etc but there are now some great alternatives out there. Hrimfaxi had not seen the Carbon X1 - looks very nice.

     

    I was considering getting the new Macbook with Retina display, but Im now concerned about Apples arrogance and lack of transparency. We all know products have issues and its how companies deal with these issues that make or break them. My iPhone 4 was one of the first ones and its battery kept dying - Apple replaced it immediately. And credit to them, they have called me once and taken data off the machine and have called again for more data, but what is missing is a public statement on a) acknowledging this and b) when they plan to fix it.

     

    Dont know about others, but my laptop is due for a refresh soon, as is my phone and I will consider other options whereas 3 years ago I was an Apple convert. The hardest thing to do is gain new customers, the easiest thing to do is lose them through bad service. Mind you Ill still keep my iPad3 for now as that works fine (but I wont upgrade to iOS 6 after this experience - no way).

     

    Power is a core requirement for any portable device. I have a second drive to go back to Lion and claim back my money for ML, but its my time they are wasting having to do all this - Im getting to the point of why bother anymore when they wont even tell us whats going on. Its all over the news and thousands are experiencing the issue.

     

    Apple - I know you monitor this forum as you have called me and removed posts. Whilst I know this is a forum for member to member communications, I think in this instance a public statement may be a wise move. I had not even heard of that Carbon X1 and now Im browsing the specs. The longer you leave this the more customers you will lose over time. Dont let that happen and please dont have reached your peak now Steve has gone.

    My two cents. I've updated to 10.8.1 so far no difference on the battery life in fact went fro 98% to 95% in less than 10 minutes. Guess they missed that one. LOL

    3% in 10 minutes = 5 hours (assuming a linear decline), how old is your machine?

    Well, I had high hopes for OS X 10.8.1 fixing the battery issue on my late 2010 MacBook Air but still no love. 

     

    Per my earlier post I let it run down to zero battery life, recharged it to 100%.  I decided to download 10.8.1 directly from Apple rather than use the App Store.  (The download is 24.2MB's but the actual install is 46.3MB's.)

     

    Initially the battery showed 100% 5 hours (1 hour improvement, but nothing close to the 7+ hours under Lion) but under normal usage it dropped to 83% 2:14 hours in about 60 minutes.  So all-in-all little to no change.

     

    I also noted that my battery's health dropped from 95.4% after 123 cycles to 93.7% after 124 cycles.  That certainly makes me nervous.

     

    I really enjoy using Mountain Lion on my iMac, there are some great new features.  I also love my MacBook Air...best laptop I've ever owned.  I really hope 10.8.2 will resolve this battery issue.  If not, I'm heading back to Lion, at least on my MBA.

    I upgraded to 10.8.1 and don't think there is much of a difference.  I don't think there is meant to be?  Who was that rogue developer who reported 10.8.1 gave him a full day charge again ---- was it a plant?

     

    I am very dissapointed and this is terrible apple.  Your silence and the industry and media silence has be surprising.

     

    My belief is still that this is a power management issue.  More related to power states and voltages of the CPU.

     

    My machine gets good battery life if you do nothing with it, but the simplest activity, browing a few pages, checking some emails, seems to use lots of power.  As if the CPU accelerated quickly to a high power state and then sticks there for too long.  You can see in coconut battery that the power usage takes quite some time to come back down.

     

    Windows has many settings for power management, but OSX seems to have very little and we are left hoping that Apple get it right -- which clearly they have not with ML.

     

    If there is no evidence that they are going to sort this out in the next week, I am wiping this machine (MBA 2012 i7) and either clean install ML or revert to LION.  What are your suggestons?

    A plant? who knows, he could be, as could you, or I.

    FWIW reinstalling Mountain Lion has done nothing to resolve the battery issue for anyone here.  Going back to Lion apparently returns things to "normal" however.
