    Another thing you can do is take a look at CoconutBattery's indication of "Battery Power Usage"

    Look at my first post on previous page (144):

         "P.S. battery power usage 8.4-9.5 Watt, before update it was never lower than 11!"

    HTManning. Fair point, I would say, after 2 or 3 reboots, the SMC resets are all cleared and it seems to settle back so I do that (Which is very quick on my SSD for me).

    Sorry, I missed the "PS".

     

    Brilliant!

    Now that sounds encouraging.

     

    Thanks again.

    You are welcome) Try to update, anyway it is better than 10.7.2

    2 hours of surfing Safari and Mail and still have 6:30 estimate time (73%). Battery power usage from 7.8 to 11. So it looks much better than before.

    Some light in the tunnel .  I have installed the patch  10.7.3 and  the battery life looks encouraging  5-6 hours with watching video VLC , browsing , downloading  and max brightness . The only thing i did is install the patch 10.7.3  and reboot - nothing else . As i write still have 1.31 hours left  ( interestingly - battery meter is showing red even  i still have 20% left  but that's by the by)

    Will watch it for few days but in general my 5p advise is  to install the patch .

    I installed the update, and got an error! After that, Lion did not restart! It only stuck to that grey screen, and I had to recover from Time Machine!

     

    I cant recommend this update, before Apple solves the problem. And I´m not the only one having this problem!

    Just installed the update about an hour ago. I used the combo update downloaded directly from Apple's site. Update installed without a hitch on my 2010 MBP. I ran repair disk permissions right after that. Can't say I notice anything different right now (positively or negatively).

     

    Its almost fully charged however, so I am about to take it off power and work straight off of the battery for the rest of the day.  Just to clarifly, I have been seeing the same battery shortage like *almost* everyone else here. Ill report back in a few hours if the update has made any changes. I am skeptical.

    This is my observation: I installed the new update yesterday.  I haven't noticed any improvements, actually, while watching a youtube video using my firefox browser, the fan was loud and the computer got very hot.  It seems that I can fry eggs on my new MBP.  (Previosuly I had a beta version, and I think it was better).

    I have been working from 100% battery down until 90% battery. Running Chrome (no videos or flash) and mail with wifi. Screen only at 3 steps of brightness. 

     

    10% of battery has equated to 37 minutes of working.

     

    Not sure if we can extrapulate this, but if we did, I should theoretically get 370 minutes of work, which is 6.16 hours. 

     

    Cocunut battery says I am using 10.0 watts and that my battery is at 93% of original capacity after 20 months of usage.

     

    Ill continue to post back if this is useful to anyone on the fence about upgrading to 10.7.3

    The University I work for just put out a warning NOT to apply the new 10.7.3 update without a full time machine backup because it is full of glitches, missing icons, and - worst of all - boot errors which are effectively turning people's laptops into carefully machined aluminum doorstops.

     

    Don't upgrade without without a full backup. Just to twist the knife: I never had windows ME or Vista effectively brick a computer.

     

    Cheers.

     

    Also, the note about SMC reset stands: it is a placebo for those of us fretting about battery life and will return to its former state as many of us have discovered.

    Now Im down to 80% and it has been 70 minutes.

     

    Carrying this out should give me 350 minutes. 5.83 hours or 20 minutes less than my previous estimate at 90%

     

    FWIW My computer estimate fluctuates between less than 5 hours and over 6 hours remaining. Not sure I trust that though.

    70% and not quite 110 minutes. I am on pace for an approximately 6hr battery life. Screen brightness is rather low, but overall I am pretty pleased. Its an hour lower than Apple advertising but my battery is 20 months old.

     

    I should note that I have been using gfxcardstatus to force intel GPU only. I have it on the power source based setting.

     

    Hope Apple still releases a better fix, but I have to say that 10.7.3 (if it installs correctly) does seem to be better for my 2010 MBP 15" than 10.7.2.

     

    FWIW, I still wish I was on SL, but iCloud was too tempting at the time.

    Heads up: take a look at the new apple store battery estimates for the macbook air and macbook pro. It reads 5 - 7 depending on the macbook air (11" or 13"), and 7 hours while browsing the web on any macbook pro. Do I remember it saying 10 hours or is it just old age?

    It seems that I can fry eggs on my new MBP. 

     

    That's too bad. I hoped that Lion 1.7.3 might solve problems and be worthy of installing next to Snow Leopard.

     

    But it seems not much has changed since 1.7 pumped my CPU, toasting my logic board (according to the tech grapevine, more common than you know).  Uninstalled.

     

    Although a lot of time has passed since my problem was resolved with a complete Apple-provided installation of all new parts, and there have been several revisions to Lion that I hope diminish the danger of overheating, it's still wise to keep an eye on your machine's actual heat.  Here's an open source application to help you do that, Temperature Monitor (by the makers of TinkerTool).  Works for me:

    My battery life has got worse if anything - only had this thing for 8 months or so and I've had it replaced 3 times!

     

    Not too impressed
