Mac OS X Lion SHORTEN the battery life on my Mac Book Pro

I have a Mac Book Pro early 2011 version running on a 2.2 quad core i7, before I upgraded to Lion, when I fully charged the battery indicator always display 5+ hours of battery life. However, as soon as I have upgraded to Lion, even I have fully charged my Mac Book Pro, the battery life indicator has never display anything over 4 hours.

I then go to change some energy saving setting, adjust the brightness, etc and finally can squeeze the battery timer up to 4:30. However, I still can see a significant shorten life of the battery.

In summary, in my personal experience of this Lion upgrade (+ some other articles online), I am quite certain that the current Mac OS X Lion (10.7) is using a lot more power than it previous OS (10.6.8). Now I am hoping Apple will release a 10.7.1 to get this power consumption issue fixed.

After my extensive testing on my Mac Book Pro, the battery life is shorten around 1 – 2 hours in normal use.

    I am totally agree with you, because i also have MacBook Pro 17″ which i bought in January 2011, after upgrading from Snow Leopard to Lion the battery is draining like a hell and having a lot of heating problem too, after getting it full charged it shows me 4 hours remaining battery 🙁

  2. Here is an article that’ll explain some hopeful ways to get back your battery life on a OS X Lion running macbook.

    Good luck!

  3. I can confirm this, I certainly hope that there will be fix. Lion brought me nothing but trouble so far, unfortunately.

  4. Until that Apple fix you could try out the link i posted above.

    Hello Howard,

    Thanks for publishing this issue. I have model of macbookpro as you have. I recently bough this mac and I enjoyed a 7hr battery life. Now the indicator only reaches 4.5 hrs but actually only lasts about 2hrs.

    I am thinking of going back to snow leopard if Apple will not address this issue. Do you have info regarding the 10.7.1? Do you know when it will be released?


  6. Hi Jess,
    I don’t know when Apple will release 10.7.1, but I think Apple will fix this in the next update. For now, you may try the method I posted about a fix I found online. That sort of work for me some how.

  7. Howard I have just made a breakthrough with the Lion battery problem. The problem all along had been with the Apple auto graphics switching. Could you post about this on your blog so that it can help everyone (and me 😉 ).

  8. Hi All,
    I really regret upgrading to LION. Now I revert back to snow leopard. Unfortunately, my battery life stuck at about 4 hours after downgrading to snow leopard. Both way you loose.
    Can the Master at Cuppertino says something about this issue. Don’t leave us in the dark.

    I installed Lion on two Mac Books, one Pro and one blackbook 13.3″ machine.

    The battery life was reduced from 5+ hours to 1.5 hrs on the Pro and from 3 hours to 1 hour on the Blackbook. Both laptops run very hot now also.

  10. Had the same problem when i upgraded from Leopard to lion . So then i started digging around and uninstalled my smcontol fan . Lion controls the fan much better now and also increased my battery life .Must be some conflict with smcontol fan

  11. I just went through the exact same situation. FIRST, at the Apple Store, they did a brand new, clean install of OS X Lion 10.7.1. That still only gave me 4-hours on an excellent battery. Then, even after clean-installing Snow Leopard 10.6.8 with all updates, it is STILL only giving me 4-hours of battery life.

    What the heck is going on? What did Lion do to my computer? How is that even possible?!

    I have a feeling the Geniuses have run into this problem more than they’re supposed to admit. Whenever I ask a Genius about it, I sense a bit of hesitation before I get a very general vague answer (“Things like this can happen with an OS upgrade, from time to time.”)

  12. Did you try this Mac Lion fix that I had mentioned earlier. It’s not a sure-fix, but hey, it’s worth the try.
