    Credit to Apple - balancing the positive with the negative


    After providing my first data to them, after they called me, I have now been contacted again to run a new program that monitors the battery use over time - their developers are definitely looking into this, but dont yet know what the issue is.


    So credit to Apple for following up. Dont hold out your hopes for 10.8.2 as it is not fixed yet as they dont know what it is, but good news is they are looking deeper into it.

    I have disabled the notifcation centre and my battery life has shot backup to 8-9 hrs at 90%.

    i have done the perminent disable by renaming the notication center app

    I made the mistake of upgrading to ML and my battery lasted about 3-4 hours.  I upgraded this morning, charged up 100%, then left the RMBP on from 11:30am-5:30pm and returned home with 32% battery life remaining.  I did not run any programs during this time except for Caffeine which basically just ket my screen on (50% brightness) and likewise the computer.  In the hour I have been home surfing the web the battery has gone from 32% to 9%. So I'm basically at 4-5 hours now versus the 3-4 hours before.  I guess the update helped slightly, but I will probably erase ML and use Super Duper to put back on Lion.  If anyone knows about any issues that might arise from this please let me know.  Thanks!!

    Hello, guys!


    I didn't really notice any significant battery capacity loss untill today (updated ML). My early 2011 15" MBP lasted about 1.5 hrs. But then when I plugged in the charger, I got the "Service battery" message. I was even more shocked when I saw the battery capacity (in CoconutBattery).

    I don't think this is normal. My MBP is still under warranty, but Apple Service here in Slovenia (EU) is such a pain and I tend to avoid it as much as I can.

    Is this a Mountain Lion problem or is my battery really dead?

    I'll add my name as another use how is now experiencing horrible battery life.  Noticed it on 10.8 and hasn't really improved on 10.8.1. 


    I'm wondering if they changed something in the neworking software or the video drivers because it seems like my battery drains my MBP MUCH more quickly than when I'm not doing anything.  It doesn't feel like a run-away process or thread, in the general sense, as much as it does something associated with the hardware - which is why I think video or networking.


    I hope that the Apple engineers can lick this one soon.

    Hey McGohan,


    Am attaching some pics, am still on that first cycle be it now counting as "1." So am fairly sure I got at least 5-6 hours, and in the watts pic the upper right corner you can see 1 hr remaining from 17%, at 50% brightness (now telling me 1h19 min. Unsing the math, 17 for 80 min comes down to 7.84 hrs total on current setting. So specs:


    -128 Gb as I wanted the Toshiba SSD following Annandtech disection of Macbook Air 2012 (256 comes with Samsung and $ 300 extra)

    -i-5 as I heard some glitches with i-7 on macbooks (from a genius) and i-5 is a superb processor on Ivy Bridge- for our needs anyway.

    - I only upgraded ram to 8.


    My reasoning is performance vs buck. At $1299 student, and buying another in 18 months, I saved $ 500 in SSD and processor upgrades, and am getting 2 for the price of one 2012 MBP thats suped up and:


    - current MBA I got is more powerful than most MBPs from last year (flash makes a difference)

    - MBA 2013 or 2014 will be superior to MBP 2012, and MBA 2014 likely superior to MBP 2013.

    - will have two machines in continuous warranty (extension)

    - Thinner, less glare than MBP (except the matte one) and higher res as 1400x900.. so MBP, 13 or 15, first time ever: NO MORE.

    - LIIGHT


    So pics below. Screen Shot 2012-08-24 at 9.11.05 PM.pngScreen Shot 2012-08-24 at 9.09.25 PM.pngScreen Shot 2012-08-24 at 9.09.38 PM.png


    And the final pic 10 min later as I typed this:


    Screen Shot 2012-08-24 at 9.24.23 PM.png

    Fairly linear and consistent. Although it goes up and down as I fiddle with the GPU taking shots. I will repeat that I think their way of calculating power by the second is really weak.


    I wonder if GPUs and i-7 are not the culprits on MBPs or upgraded MBA. Given the increasing volume of complaints, am less and less inclined to accept the batteries as the issue. Over 3 years those batteries are so diverse that they cant all be faulty. But then comes down to motherboard components and voltage/current control.


    Anyhow, got 2 weeks to try and will test it THOROUGHLY this weekend. And 1 yr warranty, will buy 2 extra in 1 year in case machine lost or stolen save the $. So I would order that MBA in all confidence but I would not go with i-7 or the higgher flash capacity and use external G-Drive hitachis, the best.


    Oh, my notification center is disabled, as is power nap, no need for them.

    I am in the same position as you are, 2011 MBP (bought it in June 2011) that is dropping battery health percentage like crazy!  I noticed on Tuesday that it was at 78% health (with 72 cycles), it is now at 69% with 73 cycles.


    Clicking on the battery now says "Service Battery"

  • Beisarius Level 1 Level 1

    gmc, plse do tell me you got warranty as that's an instant Apple battery replacement if you take it in. And when the second one fails, you get a new logicboard (they will not replace the battery 3 times). And if the same problem continues, you get another. And finally you get a 2012 machine with Apple. But only if you bought the added warranty. However, this problem is so clear for some and documented, that this is not something you caused with normal usage and resulted from the upgrade. So you are likely entitled, legally at least, to a functioning product even after the expiry of warranty. At least in Canada a consumer is covered that way.

  • gmc74 Level 1 Level 1

    I would love to say I did, but I did not.  I hope they will consider this abnormal, being at 69% with only 73 cycles has got to be considered abnormal.

  • OsvaL Level 1 Level 1

    Same problem here:


    Macbook Pro 15' (Early 2011)

    Only 35 cycles and after Mountain Lion (and the 10.8.1 update) now I have 0% health and the "Service Battery" warning sign.


    Something weird is going on and a refuse to buy another battery, before Mountain Lion my battery had a health of 98%.

  • OsvaL Level 1 Level 1



    Check my last post, I have the same MBP with the same problem, your battery health will decrease to 0% over a short period of time.

  • OsvaL Level 1 Level 1



    Things got worse... I tried to reset the SMC and now...




    My MBP is completely useless now...

  • devilsgenius Level 1 Level 1

    I have been facing the same issue since upgrade.
    At 54% health, and "Service Battery" after clocking only 180 cycles (172 when the issue started).
    Sadly, I'm out of warranty too (15 months). Either way, this is an abnormal issue and Apple ought to give us some kinda discount at the least.

  • devilsgenius Level 1 Level 1

    Looks like I'll get to you situation pretty soon.
    Seriously annoyed with Apple now.

  • __fb Level 1 Level 1

    No intention to be rude, you didn't hear the intonation in my voice.

    Apologies if it sounded rude.


    What I was trying to say:

    While I absolutely follow your reasoning (and would assume the same), the reality is:

    After disallowing incoming access to dropbox, everything works fine. (at least appears to for now)

    Before then, the finder went berserk whenever dropbox was turned on and any (not only dropbox) finder windows open.


    In any case, good luck with your issues.
