    Does anyone notice a decrease in battery life from Leopard to Snow Leopard? I have the new 13" MBPu with the 2.53 GHz processor. I used to get between 5 and 7 hours. Now it seems to tell me i'm only going to get between 2 and a half and 4. Will this fix itself or whats up with it?

    My first gen uMBP is showing 2:24 left, with 95% battery left.

    However, that is with my screen one notch from full brightness, fairly loud music, Adium/iTunes/Skype/FireFox open, and charging my iPhone.

    Give it a few days to calibrate itself - you may well find that it returns to normal...

    Pretty dramatic decrease, probably not a correct value..

    make sure you bring your screen brightness down and get your settings to where they were before.

    Argh. Tiger to Leopard reduced my battery life, and I was hoping that SL would improve it again. This doesn't bode well :(

    SL Ate close to 30 minutes of battery life - brand new battery, used to get 3:00 hrs on full charge and now it only gives 2:36 hrs. And it is not a reporting problem - it does only last for around 2 and half hours.

    :mad:

    For those talking about less battery life... I think it will just take a few cycles before it gets to where it needs to be. I noticed my battery said it was charged and the green light was lit on the power adapter. However, If you switch to percentage it only says 95% full.

    When I unplug the cable and bring my brightness down I am getting about the same as what I was getting before, however I am still bothered a bit by the 95% and it saying charged. Anyone experiencing similar stats?

    Once the battery is charged it will not start a re-charge until you go below 95%. Just let it run down a bit and then plug it in again. It will go to 100%.

    I'm also seeing a big decrease in my 13" MBP since installing SL tonight. At half brightness with Mail, Safari, Adium, and Firefox open I've seen my battery estimate drop from 4-5 hours to 2. Also hearing my fan kick in pretty much continuously which it never did before.

    confirming battery loss

    i just upgraded to snow leopard on a macbook pro4,1

    before the upgrade i had 3-4 hours of battery life. after the upgrade i get 40 min to one hour.

    i have reset the pram and other settings. and upgraded to the latest verion of snow leopard

    is this just a scam to force people to buy new batteries ???

    check to see if bluetooth somehow got turned on... I bought a new magic mouse and when I went to enable BT, to my surprise, it was already on. I'm "certain" I turned it off when I first configured Leopard. Just a guess though

    that sounds rather excessive, I wouldn't peg it to SL, see if there is something else that maybe wasn't upgraded possibly?

    Mine decreased as well. MBP 5,1 unibody 2.53. Went from over 5 hours to less than 3. This is with wifi/bt off, screen dimmed as far as it can go before the screen turns off, and after a fresh restart. :(

    Reduced battery life snow leopard

    In my case, seriously degraded battery life (1 h 30 min with full battery), permanently running fan and increased CPU temperature (78 C) was caused by an old 32 bit version of antivirus software (Sophos) that was constantly running in the background.
    Upgrading to the latest 64 bit Sophos version completely eliminated the problem. Fans are off, CPU temp dropped immediately to 57 C and battery life is back at 4 h 30 min (this is still an older Macbook Pro 13" with removable battery).

    Check what software is running in the background.

    Battery Life

    So, just upgraded to 10.6.5 with my 15 inch MBP. I'm seeing lots of battery problems.

    1. Low Batter Shuts off Computer: When my batter gets to around 20 minutes remaining, the computer dies. Not goes to sleep, shuts off completely. This didn't happen before.

    2. My Battery Health has been as low as 32% and now it's at 85%. This isn't right.

    3. Batter life is REALLY bad.

    Is this something to just accept, or will they fix this?

    Try calibrating your battery, that should help with the battery meter being more accurate. Instructions can be found through a Google Search or an Apple's website, but the gist of it is to leave your computer fully charged for at least 2 hours (connected to a power source), let the battery drain fully until it turns off, leave it in that state for at least 5 hours, and then let it fully charge back up and remain connected to a power source for about 2 hours after it has been fully charged.

    Also, download CoconutBattery to get stats on your battery; if you're seeing that dramatic of a drop in health and you're below 300 cycles on your battery, Apple should replace it for you for free.

    Wow I'm glad I don't have any of these problems...that's so weird how upgrading from leopard to snow leopard is giving everyone these problems...I hope when they upgrade snow leopard it doesn't do the same thing. I'm perfectly content with the 6:30 hours of battery I currently get with my 2.26 MB I bought in November ;)
