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?

MacBook Pro, Mac OS X (10.7), 2.4 GHz Intel Core 2 Duo, 4 GB Ram

Updates:


I've decamped to Starbucks for the day, so I'm going to be blogging/web browsing using WiFi and battery power today. At 10:45 am, I had 100% battery power. It's now 11:15, and I've got 87%. I'm not using iTunes, and my display is at about 50% brightness. If you care to follow along, I'll be tweeting somewhat regularly @michaelempric: http://twitter.com/michaelempric


If the battery issues continue, I'm right by the Soho Apple store, so I might swing by and have them take a look as suggested by the AppleCare tech.

It depends on what programs are you running. I found, that Skype even it's not in call mod, just running in backround using the AMD card. When I quit him, Macbook automaticly switch to Intel. And as anybody wrote down on page gfxCardNotifier is good solution to view what card is being used. Also supports growl notification.

Sorry it is gfxcardstatus. But anywhere I also observe same symptoms as all of you. Before Lion upgrade my Macbook PRO 15" 2.2 late 2011 battery life was about 8hours with internet browsing, skype and adium icq online, mail online. Now with Lion it is about 5hours. So that is horrible apple because I bought Mac with dedicated 8hours battery and now I have standard expensive PC laptop.

Day two after installing Lion: I have my MBP sitting in front of me open. Started off with 3:57 battery time (low for just waking from sleep after charged overnight). Only Safari and Spped Download were the open apps and I wasn't using them - just desktop screen showing. In twenty minutes went to 2:01 remaining. Opened Activity Monitor and the only significant process shown is kernel_task at 22% and mds which ranges 0 to 88%. Don't understand enough to know what that means except to share it so help can come from Apple for a fix!

I had installed Lion on my 2011 MBP 13" i7 yesterday.

Left it charge to 100% then disconnected shut down and

went to bed. This morning I spent 2 to 3 hrs messing with it

on battery, some web surfing, some internet JAVA based

games for a while, and browsing and commenting on this forum

while I was cleaning up my iMac and installing Lion on it.

Battery went from 100% to 73%. Also as a side note, CPU ran

at around 38C with fans at 2000.

As some of the other users have suggested, try grabbing gfxCardStatus 2.1. I was initially worried at the battery life I was getting and started to dig into things.


Launching Chrome, Firefox, Keynote, or Skype triggered a change to the discrete graphics card. I have an early 2011 MacBook Pro 15" 2.2GHz i7.


Right now I am working in InDesign CS4 (which oddly does not trigger the change, Illustrator and Photoshop however do.), Word 2011, Safari, and running iTunes in a fullscreen mode off to the side. With 40% of the battery remaining, I have @ 3 hours of charge left, however it does fluctuate down to 2:30 depending on how much I switch between Word and InDesign.


I colleuge was having the same issue and was able to replicate the graphic switching issues on his 2011 MacBook as well ( 2.0GHz i7 15"). I am not sure if this is an OS issue or application one, but hopefully this narrows it down for some people.


I am getting slightly better battery life with the integrated graphics, average when the discrete is turned on and using an application, slightly less when the discrete graphics is under a heavy load (World of Warcraft or Starcraft II)

Same issue here. I have a 2010 15" MBP w/2.4GHz Core i5 and 4GB RAM. Display is set to less than half brightness, using gfxCardStatus with integrated graphics when using the battery, WiFi enabled, not doing anything particularly power-intensive, but the battery is depleting much more rapidly than with Snow Leopard. I usually get about 6-8 hours depending on what i'm doing, but after an hour of web surfing I'm down to 60%. Laaaaaame.

I just called Apple support and they talked me through resetting the power manager, the battery now seems to be fine. I can give you the steps the gentleman over the phone gave me, it might just help.


1. Turn off the computer.


2. Hold down Ctrl+Option+shift


3. While holding down these button, press and hold the power button as well.


4. Hold all buttons for at least ten seconds.


5. power back on the computer.


For me that worked, i don't know how it will work for everyone else but immediately my power estimation jumped up to around 9:30 and 10 hours. 🙂 Which is two hours more than i started with.


Jul 22, 2011 12:48 PM in response to Michael Empric

I reset the Systems Management Controller (SMC) as per the above (you can also find it here at http://support.apple.com/kb/ht3964). I do get a bit higher estimate -- 1h56m at 47% battery. Still, that's a lot lower than what I used to have. I have a 15" MacBook Pro with 2.2GHz Intel Core i7 + 1GB video card that I bought earlier this month. Rumour has it that Adobe Flash has some issues with Lion that keeps the computer at ramped-up mode, and it's running pretty hot still.
