    mine this morning when i close the vmware fusion i was shocked with what i saw.. it was 11hrs O_O then after a few minutes becomes 8... but still this afternoon i went to apple service center and leave there my mac.. they said they will change the battery... need to wait for 1week.. miss my mbp already... /sigh =(

     

    Just a note...running a virtual machine like VMWare Fusion or Parallels uses a great deal more power than just normal day-to-day use on a MacBook.  So I wouldn't expect 6 - 7 hours while you're using it.

     

    Hope the new battery gets things back to normal!

    ok. can I ask peoples oppion please - first here's my history...

     

    • I have a mid 2012 retina macbook (that came installed with mountain lion)
    • I did a timemachine update to the machine with some of my old computers data (which was running lion) - it didnt update system files, just my user profile and data
    • the laptop has never held more than a 3.5hr battery charge (if never even estimates more than that)
    • went to apple - they checked the battery and said it was ok
    • they said I could get it replaced but recommended I waited for a software update
    • this was a few weeks ago and Ive now lost patience

     

    my question... is it worth me trying to do a clean install of mountain lion? annoyingly I didnt check how long the battery lasted BEFORE coppied accross my time machine data - and Im wondering if that would have any effect

     

    this is the last thing I have to try - Ive done all the memory resets etc and nothings worked

     

    thanks for your help

    The "wait for an update" is a brush-off IMO.  There are millions of MacBooks out there just like yours that work perfectly fine.  I still say that since your MBr is under warranty the responsibility for making it work right is Apple's, not yours.  Doing a fresh install on your own won't void the warranty, but it might give them another excuse for why it's not operating properly.

     

    My advice is to go back to Apple and politely demand that they do whatever it takes to make it meet their specs or replace it.  Don't give up until you're satisfied.  They will take care of you.

     

    Worst case, if they install a new battery and it works normally, you have a new battery and a great MacBook.  If that doesn't do it you have a new battery and they still have to make it right.  If that means that they have to do more, like replace the logic board, that's fine.  If all of that fails you will get a replacement.

     

    If/when you take it back for a new battery ask them if they will do a fresh install of Mountain Lion.  (Be sure to do a full TM backup first of course.)  Then take it home and see how it runs for a bit.  If it looks good I would manually restore it rather than a TM backup restore.  You can still access your TM backup (providing that they use the exact same user name to set up the fresh install - be sure to tell them that).  Then pull your documents, etc. onto your "new" hard drive.  Download and install your apps again.  That way you're guaranteed that everything is "clean" and that you're not importing old preferences or other cruft that might be problematic.   

     

    So long story longer, you paid good money for your MacBook and you should not have to tinker with it to get it to work properly.  End of story.  Make them make it right.  My two-cents.

    thanks Richsadams -thats my view exactly

     

    the only problem is, I dont want them to take the compute away from me for days to see what the problem is  

     

    I was thinking that if i do a clean install and check the battery a: if it doesnt make a difference then I know that that's not the problem, or b: it fixes it and i dont have to take my mac in to be repaired.

     

    I suppose Ive answered my own question really.  I just dont want to be left without my computer for days on end.

     

    PS: I'm not quite sure how to reinstall all my iphoto, itunes etc from a timemachine backup (without simply using the auto function)  is there anywhere you know that demonstrates how to do this?)

     

    thanks again for your feedback - much appreciated

    Again, a clean install isn't going to do any damage, but I'd rather Apple take responsibility.    Depending on what stock they have on hand, they might be able to replace the battery while you wait, or within 24 hours at least.  You could always call the store, tell them you'd like to take them up on their offer to replace your battery and ask them how long it will take.  If they don't have one on hand they can order it in and let you know when it arrives.  Swapping batteries is very simple...five minutes tops.  If they want to keep it to run diagnostics or whatever, that's another story of course.  Be up front and tell them that you cannot be without it for any period of time.   

     

    But if you want to try a fresh installation, a full TM restoration is one of the options given when you reinstall the OS.  It looks like this...

     

    lioninstall-transfer-586-245845.png

     

    To avoid importing any problems you would choose "Don't transfer now".  Then set up Time Machine as your backup disk, but leave it in the "Off" position until you've grabbed your files.  Remember to use the exact same username (upper and lower case letters count) when you set up your new installation or you won't have access to your TM backup.  If that happens you can always reinstall the OS again using the correct username.

     

    Once that's done reinstall the apps that you need...iPhoto, etc.  Then you can open Time Machine and once it's active you will be presented with a finder window.  On the RH side select the date from which you want to restore your folders or files (probably your most recent backup) and navigate to the appropriate folder and click "Restore" on the bar at the bottom of the TM window.  For iPhoto you would click on "Pictures" in the LH finder window, then click on the "iPhoto" file and click on "Restore" in the bottom of the TM window.  That will copy all of the iPhoto files onto your "new" hard drive.  The same goes for iTunes, Documents, etc.  Here's a nice tutorial:

     

    http://pondini.org/TM/15.html

     

    Of course doing it this way will require you to set up all of your preferences and such again.  A bit of a PIA, but at least you'll know that you've done everything you can do to avoid some issue following you to your new machine.

     

    Hope that helps and let us know how it goes!

    I did a clean install and the battery is the same. No improvement. At a full charge I get 3 hours and 30 minutes.

    I find it interesting that at first I thought the 10.8.2 update really did improve my battery life on my Macbook Pro.

    But then last week I got a 10.8.2 supplemental update that seems to have hurt those battery life gains? I have found that just not using Notifications and turning off some other stuff through terminal hacks makes the biggest difference in batt. life. I just think Mountain Lion has become bloated with back ground services and those of course can make a difference when added up. ML has been a big disappointment to me as I typically ran a Virtual Machine with my Macbook Pro running Windows 7 and between that setup drawing battery life and OS X increasing its draw. I have been forced to abandon the Virtual machine because of the battery life issues.

    It is only my opinion but it seems that OS X has turned the corner from being a efficient OS to being a OS filled with bloated features and services trying to make itself more palatable to IOS users. I would not mind so much if users like myself with no interest in syncing, or moving between Apple devices could turn off these services.

    But like I said early, a terminal hack is so far the only solutions.

     

    i have problem same like bro..any help

    Apple defines its wireless productivity test as "wirelessly browsing various websites and editing text in a word processing document with display brightness set to 50%."  Anything beyond that, can reduce the amount of battery life and it all depends on what else you're doing. 

     

    Watching videos is GPU and even more, CPU intensive, so you should expect the battery life to be less. 

     

    A quote from a bench test article of the MacBook Pro Retina:

     

    The second time around, we primarily looped an DVCPro HD QuickTime file using QuickTime Player X from 8am until the MacBook Pro forcibly went to sleep around 12:46pm -- a pretty reasonable four hours, 46 minutes of constant use with the screen on the entire time.

     

    This article refers to 2011 MacBooks, but is pretty much applicable to any model...

    Hi Richadams,

     

    I have read this thread for a long while and finally this morning I decided to do a clean install. I have a mid 2012 MBP retina.

    After this clean install, I got 2h30 !!! Disapointed ! But I remembered reading that we have to do a SMC too. I did it.

    And miracle ! I get now between 7h and 8h30. Very happy ! And it remains at this level for a while now.

    I will use now your advise above to get back progressively all the files from Time machine, without doing it automatically.

    Many thanks.

    oh poo - I was going to give that option a miss now looks like I may have to give it a try after all! mmm...

    Im wondering what an SMC is.

     

    It might help to list your CPU along with battery life.

     

    The 7 hours battery time is given across all models, but the CPU goes from 2.3 to 2.7ghz.

     

    A few years back sony did a similar marketing campaign with battery life, but upon close scrutiny, its a blanket life - the lowest processer will achieve this, but the highest one wont.  Makes sense because a bigger processor is a bigger power consumption. 

     

    That said, there are firmware issues for some reason.

    jmorandeau Level 1 Level 1 (0 points)

    SMC =System Management Controller

    2.6 ghz

     

    Better read the thread, you will see that this problem is a real one, not only marketing.

    Yep I got that Jim.  There is a problem, though not in everyone's posting - that's the marketing bit.
