Lion - Horrible MacBook Pro Battery Life

After upgrading to Lion, my MacBook Pro battery life has been severly affected. After 1.5 hours of light web browsing, my battery has decreased to 40% from 100% after charging all night.


Notes: Spotlight completed indexing the hard drive over night, and the laptop remained plugged in charging. The fans seem to be running normally, not at a higher rate. The backlight is at 50% brightness.


Thoughts?

Unfortunately I can confirm that resetting the SMC on my MacBook Pro (Mid-2010) only gave me a ‘normal’ reading for a couple minutes after turning my Mac on.


Now it seems like it’s still draining way faster, just like before. I normally got 6-7 hours on Snow Leopard but now it’s down to around 4 on Lion. I guess I can only hope an update is on the way.

Hi Omolina,


Without the install disc and/or a backup of your system, you're in a bit of a pickle.


I fully share your frustration with Lion, especially in terms of the loss of battery-life. But can you hold tight for just a bit longer? Before going through the chore of an OS downgrade, perhaps it would make sense to wait and see how (if at all) Apple will address our problem.

I too am hoping for a speedy resolution.


Meanwhile, am noticing that the remaining time displayed for my battery is highly erratic.


This evening, in a matter of minutes, it has gone from 9+ hours to 3+ to 6:09. I realize that the display is only an approximation, and that the number is greatly impacted by [specifically] what we are doing with these machines. Using Flash Player, for example, ***** the life out of the battery. But I've never seen it go from one extreme to another in such a short span of time.
