    10.7.3 installed, could not shutdown at first, hard power off and reboot and reset PRAM later using 9.1 watts 1/3 brightness, nothing installed but Pages and report is 5hrs just on the net posting this from a full charge.  Going to reboot a few times and then monitor actual use on battery rather than the meter.  Will report back.

    Let your mac finish some system processes after update. In my case it took about 10-15 minutes, CPU was almost 90%.

    Rebooted three times, cpu at 3-4% web browsing to this site, reporting 7:09hrs.  99 percent remaining.  Now timing normal web use only.

     

    Noticed that gestures still uses a good 15% processng power!

    Flash still eats 15% of processor power on www.bbc.co.uk! whilst QT holds back at 6%.

     

    Half our surfing amd 10% gone so that rate 5 hrs

    How long is your sample? is 99% after 1 hour, 1 minute or 1 second?

    Maybe a bit off topic but I never noticed this before the update... Is it normal that my battery gets discharged a bit even when I'm using the power adapder? I am using Logic Pro but no extreme CPU usage... It went from 100% to 95% even though I'm plugged in...

     

    + OS started indexing the drive a couple of hours ago even though I applied the update yesterday...

    I just updated to 10.7.3 and it's worse if anything. After 45 minutes of light web browsing (using the Integrated Graphics Card and everything) I have 71% of battery left and (1:52 hours). It's ridiculous. I have the mid 2010 2.66 i7 Macbook Pro. As I bought it secondhand and it already had Lion installed I don't even have Snow Leopard on a disc to reinstal it and it's annoying to realize that my battery won't last 7 hours of light use as I was expecting.

     

     

    Update: i looked again and it says 3:31 hours remaning at 69% of battery. Seems like it is the same as it has ever been (with Lion). It lasts a maximum of 4 hours, and being a 2010 model it should last around at least 7 hours of light use.

    Second update: now at 61% my battery went down to 2:11 hours. So more than one hour in 8% of battery. I'm running chrome and skype only (away) and I'm stil using the integrated graphics card. I don't know what else to do...I've tried the system reset but it doesn't change absolutely anything, to the point I even doubt being doing it right, but there's little you go go wrong pressing three keys together...And I've done it around 5 times.

    I'm seeing no significant change for the battery life...

    I've read through this topic over the course of several days.

     

    One thing I'd like to know is what are the specs for these MacBooks that have less than expected battery life. I'm getting around 4-5 hours with the specs below from a full charge.

     

    At idle, with 50% brightness Coconut battery utility indicates I'm using 10-11 watts. That is with no apps running. The CPU speed, amount of RAM and hard drive model will all make a difference. So let's post our specs and see what we can find.

    Yes, I did all of the mentioned tweaks. Reduced brightness, turn off airport, bluetooth, etc....  I remember getting 10 hours with Snow Leopard..

    Yes, me too. Battery life WORSE, speed WORSE!

    Why do I get the impression that Apple are concentrating on iphone and ipads at the expense of their computing side.

    For what it is worth, I did the over the net update on my MBP (early 2011).

    I am seeing much better battery life. If I monitor the current being consumed it used to start of at ~ 900ma and end up mostly over 1A, even on the integrated graphics card.

     

    Now, its running at ~ 700ma after a fresh boot and time to settle, and a day later, is still only ~ 800ma while I am typing this (Chrome).

     

    Of course,once it swiches to the discrete graphics card, all bets are off, and it eats batter like there was no tomorrow. I suspect that most people complaining about poor batter life are not using gfxCardStatus and don't know that they have the discrete graphics engaged.

     

    It also appears to be eating less memory than it did.

     

    Going in the right direction as far as I am concerned.
