    I also have similar battery problems with a battery I had replaced just prior to SL installation.
    Additionally the computer seems to run "hot" much more frequently (i.e. the fan kicks in and it actually is hot to the touch). Oddly enough when I remove the battery and run on the AC adapter it cools off.

    The info I get is: Fully charged-yes
    Charge capacity (mAh) 1102
    Cycle count---------92
    Condition ---check battery
    Manufacturer----Sony

    What to do?

    Hi hi,

    I had the same battery issues 3 months ago. I went to apple, and indeed, my battery turned out to be dead after the test. Strangely i found that my apple care does not include batteries, so i had to pay for a new one myself (although it had 148 cycles and was 368 days old).

    After purchasing the new battery, I calibrated it according to Apple's wishes and (since i had the experience) decided to re-calibrate twice a month... just to be safe.

    Here we are 3 months after installing the battery and the "service battery" notification is back. Running Idle, my battery holds for a max of 2 hrs before it needs recharging again. This now means that i've used up 2 batteries in 15 months after purchasing a over €2000 costing MacBook Pro...

    Since I'm a sound engineer and are recording outside on a day basses.. My MBP is vital to my income and missing it would mean i can't perform my work (= no income). I will contact Apple tomorrow, but can already see the discussions that are to come.

    Did anyone else have the same problems (after replacing the battery) ??

    Kind Regards
    M. Blaak

    I now am running Mac OS X 10.5.8 and I have eliminated the battery issue. Took two weeks for it to go back to normal, but its back to its working state. Something that you will have to look out for if you opt to downgrading your operating system is keeping all your data in tact. Especially if you're a sound engineer and have all your recordings on your MacBook Pro.

    Your old battery will work as well if you downgrade.

    Hello,

    Seems we have another proof that Snow Leopard has a serious bug with some MacBook Pro...

    @Michael Daeche

    When you say "It took Two Weeks..." you mean that the battery recovered its health very slow, like day by day?

    Hi hi,

    Well, I found another way to gain battery power I guess. I put my battery in the freezer for a couple of hours .. After that, did 6 calibrations in a row and guess what.. within a week by mAh is up from +/-4100 to +/-5100.. lifespan is up to 4 hrs again...

    Let's see what happens next..

    Snow Leopard indeed seems to have a power bug

    NOOOWWWWWWWWW i know why they called it SNOW LEOPARD!!
    we should have guessed that as a matter of fact our beloved leopard has a bit of snow on its head, check ur Snow Leopard retail box

    Can everyone please send a bug report to Apple on this issue. The more bug reports the merrier!

    Yes Maurice, the old trick of bunging a dying battery in the fridge can sometimes give it a bit of a lift (so can heating one up, paradoxically), but when it responds to such treatment it says a lot about the battery and nothing about the OS that it is running under. I'm afraid you'll find it is unlikely to last for too long though.

    Instead of wasting time on nonsense about Snow Leopard the remaining players who want, rightly or wrongly, to give Apple or Sony a serve in this thread would be far better advised to focus on the problem of batteries falling well short of the originally expected 300 cycles at 80% capacity without treatments like yours.

    This is really all about bad batteries, not bad operating systems.

    Cheers

    Rod,

    I stil don't see how you can argue this point when one of the posters above (a few pages back now) said that 100 of the batteries in the MBPs in his office had been affected by the SL upgrade and people down grading to Leopard suddenly find their batteries coming back to life! It has to be the OS!

    If it is any consolation I hear that Windoze 7 users are reporting the same(or similar)( problems.

    Dear Mr Rod,

    I'm very sorry to hear that my method does dot comply with your rightly or wrongly way of solving the problem.

    I also wane take this moment to thank you for kicking me out of your "player" society. At least from your comment that addresses "the remainder of the players" I conclude that i'm no lo longer part of it (Not that I ever signed up). Thank You !!!

    The facts are simple...

    These problems start as soon as you upgrade to SL. Yes, dying batteries happen on other OS systems (indeed, also windows). but if you look at the numbers, the upgrade to SL issue jumps out to extremes.

    After going back to Leopard, Battery life will (slowly) return to normal. there are so manny treads about this, and it seems to really work.. only thing is if the owner of the MacBook can downgrade and stay compatible with whatever he/she is doing.

    Apple does not admit to this problem and hides behind all kinds of excuses. From installed software to smoking behind you MacBook (The smoking part really happened). Big change apple won't do anything about it, and your left at the grace of the person helping you in order to obtain a new battery.

    If you ask me, it has got something to do with the way OS handles charging batteries. The New MacBooks have almost no issues (compared to the older ones), but hey use different batteries to my knowledge. So, It has 'NOTHING" to do with just a bad battery. But again, that's just me..

    As for my litte freezer experiment... It worked.. maybe for a little while.. but still Over the last week or so i could use my mac without any problems. I was just putting the option out there for those who need to work "wireless" and got no option to work with a power chord. May it help them to gain a little bit of lifetime.. maybe it helps. Ain't that why we subscribe to forums.

    And then as a final advise.. Do what you want, but i suggest to NEVER heat up a battery... paradoxically or not.

    A

    I assume you are referring to zenmoused's comment ajophoto.

    What he/she actually says is that:

    +My company owns about 100 MacBook Pros, and 80 of them are showing "Service Battery" or "Replace Now" after upgrading to 10.6.2. I brought in one computer to the Apple Store and they replaced the battery under warranty, only for it to have the same problem a month later. The other computers all show relatively low battery cycles (about 120) but they all insist they need to be replaced.+

    There is nothing said there about batteries "coming back to life" after reverting to Leopard, and only one was actually taken to Apple for testing, etc etc.

    If these computers are all pre-unibody models (the subject of this thread), then the youngest of them will already be close to 18 months old. This is pretty much the average life expectancy of these batteries from what I've seen here. I've been answering questions about battery failure on MBPs here since at least 2008, from users running first Tiger, then Leopard and now Snow Leopard. Still am. I see just as many complaints of premature failure in this forum from Leopard users even today as I do from those who have adopted SL.

    Let's look at the two hypotheses.

    Hypothesis 1

    a) Apple batteries in these computers under OS's earlier than SL really do usually live to 300 cycles and three years or more of age as originally claimed, despite the well documented early problems that occurred with these batteries and the thousands of reports that there have been in these forums of them dying well before this time under Leopard and Tiger.

    b) Under Snow Leopard this is no longer true. It is only now, with SL installed, that many of them die before reaching 300 cycles and three years of life. The thousands of reports of them dying at a couple of years old or less, and at less than 200 cycles under Leopard and Tiger are just pure co-incidence.

    c) the fact that a couple of million of these batteries are now a couple of years old and that this happens to coincide with the release of SL is irrelevant. Something magic would have stopped them dying in the same fashion and at the same rate as those of people not using Snow Leopard if people hadn't installed it.

    c) Therefore Snow Leopard is killing batteries and Apple could fix it if they wanted to with a simple software update but are too lazy or incompetent to do so.



    or

    Hypothesis 2

    a) The batteries in pre-unibody MBPs have an average life of a couple of years and in most cases a couple of a hundred cycles. Some die younger and some die older, but most die between 18months and 21/2 years of age.

    b) This pretty much equates with normal lithium battery lifespans but is a bit less than was originally claimed for them by Apple.

    c) At the time when Snow Leopard was released a couple of million non-unibody MBPs were around this age.

    d) When Snow Leopard came out millions of MBP owners installed it.

    e) there are some situations in which Snow Leopard makes higher power demands than its predecessor and these are likely to expose defects in a failing battery

    f) Snow Leopard's new "Service Battery" warning helps to alert people to problems which they otherwise probably wouldn't have even noticed until they became critical.

    g) It is therefore not surprising that many people who installed Snow Leopard on pre-unibody MBPs became aware of battery problems at about the same time.

    h) Apple aren't saying much about such things because these batteries haven't lasted as long as they expected them to and there are one heck of a lot of them in circulation.



    I know which argument makes better sense to me!

    Cheers

    Well put, Rod.

    I would also observe that if other OS's are experiencing similar problems, it is much more likely that it is a battery issue than an OS issue.

    Okay, but then how do we explain the batteries dying out within 1 hour... Even if the test says the batt is still okay. And if we downgrade to Leopard the battery time increases to 3 to 4 hours again. Does the batt. repair itself, or do snow leopard and leopard handle batt. management differently.

    When I had my first batt failure I've got the notice saying "service batt" within weeks.. Life time was still okay. Apple told me that it was just a warning, nothing to worry about. After 3 months though, life time was less then 30 minutes. Battery (and MBP) where just over 365 days old (just over 180 cycles) when i replaced my batt. Now, 3 months later, my system is failing again.

    I also noticed that as soon as I stop re-calibrating the batt. management (the one where you remove the batt. and hold the power button for 5 sec) the mAh drops fast, same as the lifespan. If i do (on every recharge) re-calibrate, the mAh stay around the 5100 and lifetime stays in excess of 3,5 hours. Doesn't that also show that the the way SL handles Batt. Management is at fault.

    A batt can default at any given time, no matter it's lifespan. But is you look at the statistics, you can safely say that an extremely big part of these complaints appear after a SL upgrade. This can be written off as a batt. problem... There must be more that that

    Kind regards,

    Apple didn't say anything much about the problems that 10.5.6 caused with people's apple airport cards either, but as soon as SL came out the problem was mysteriously fixed!

    Apple never own up to any issues that they are not able to fix/patch - the same goes for most corps. They don't want to have to issue a recall and want to protect their share prices etc. So just coz they haven't said anything does not disprove this SL/battery theory, in fact I'd suggest the reverse is true. If there really was no issue they would come out and say so...

    Anyway, I seem to recall that there was a comment earlier in this thread that alluded to the fact that Apple does know about this problem and are fixing it.

    Anyway, I still suggest people send in a bug report, if they have not done so already and for the record my battery is only a year old with a cycle count of 46.

    Amazing this has gone to 78 pages of debate already. I guess it helps when some contributors are willing to take up 2-3 pages in a single post

    Anyway, I think all of this conjecture is rather trite. The fact is that an Apple engineer - yes, someone who ACTUALLY works for Apple - has confirmed that this is a known issue internally. It IS a fault with the way in which the SMC chip reports battery life and it WAS introduced as part of Snow Leopard.

    So, happy for people to keep posting conspiracy theories and claims that posting on these forums for years gives them credibility to deny what Apple themselves have said, but there you go. No pleasing / convincing some people.
