    Just a reminder that Franc_iphone's trick of logging out then logging back in while holding shift still has a positive effect on battery life. Using gfx cardstatus and setting it to discrete for 5 seconds then back to integrated is also still helping.

    You'd be suprised how much it'll gain.

    I've done as you said (deleted all cookies, not just Google, cache cleaned too) and didn't see any difference. Not sure how this should change my battery life since I use Chrome most of the time.

    Then if you're using Chrome you'd probably do that in Chrome, not in Safari. I'm not sure how it'll store 'em.

    With Safari I've found Google's cookies to be particular persistent and won't be dumped unless I empty Safari's cache.

     

    It is really weird that as Google's cookies are deleted the battery life estimate time grows by 50% or more.

     

    I'm gonna see if it's gonna be reflected also on the real battery life.

    Well after trying a complete reformat and fresh install of Lion then restoring a full time machine back up with applications and everything which helped quite considerbly and updated all the said updates my battery life is slightly better than pre-update but not significantly so where I would say everyone should try to clean install Lion. However I am currently in Bath on buisness and as I dont live anywhere near a apple store normally i decided to pop into the genius bar here. Told the dude behind the counter of my problem told him i tried everything i could to solve the battery issue, he said there was no known issue that he knew about with Lion using more power but he said it with a cheesey grin on his face as if he **** well knew.. Anyway the upshot is they ran a full system check on my computer everything came back ok but he said he would replace the battery as a goodwill gesture to see if it would help as it should be lasting more than 3 and a half hours.

     

    Now my macbook is 11 months old and 115 charge cycles. and judging by the way they dealt with it I would feel pretty confident saying that if any of you that have a mac that is in warranrty that they will replace your battery free of charge without quibbles i know this wont help the actual issue of battery degredation in Lion but at least if like me you have cained your battery over a year by constant recharging at least you can make it as good as new once more. So hopefully by the time it is ful sorted (if ever) i wont have a battery operating at 80% capacity.

     

    HTH

    That's not so planet friendly…

    Oh dear someone always has to have an opinion. To be honest i could not give two hoots about the planet after i spent the best part of two and a half grand on a laptop, so stick that in your green rear end and smoke it!

     

    Note: I have lived in Brazil on and off for some time now so if you think replacing a rechargable battery is environmentally un-friendly then you should consider where all the special metal based commodties come from that make up the bulk of your daily computer high-tech life and then consider where the paper you use to write on comes from and then ask yourself why there is not much of the Amazon remaining.

    Why do you have to flip out for a normal consideration?

    If only after one year a battery has to be repelaced, than that's not planet friendly at all. Which means also it costs money.

     

    I've been in living in Brazil too, when Cubatao (San Paulo) was an inferno.

     

    PS I think you'd better watch your language, I bet if we meet in person you'd gonna be the one sticking his own head in his own redish rear.

    Okay. I received an invite from Apple to check out Mac OS X 10.8 "Mountain Lion", and as it stands now, I can't see any improvments in the battery estiments in ML as of yet. I am timing the battery life indepentantly cus we all know the estimate that the OS X has isn't always the most reliable.

     

    As for ML's new features, Notifications is nice, Messages is defently still in Beta, Reminders and Notes are nice. I like that the software updates are handled through the App Store and not separately. I didn't understand why Apple left the system split the way it was with Lion.

     

    Right now I'm running with 4 tabs open in Google Chrome. Mail is open, AppStore is open, I have a Torrent download (via Transmission) open, Steam is downloading Portal and Portal 2, and Twitter is open.

     

    Currently the indicator is reading 58% with 59-minutes left on life. This is my first full battery charge and discharge with ML.

     

    Hope to have more news later next week.

    Okay. Got the battery down to a complete 'empty' state of 0% with 0:00 on the time. Just plugged back into the charger (have some downloads that I don't want to drop with a dead battery).

     

    As for the real-world time: 1 hour, 46 minutes, and 13 seconds on an early 2008 model 15" Core 2 Duo MBP.

     

    I'll do some more tests over the next view days. ML is sitll pretty solid, and while it's still beta, I feel that if I wanted to use it as my daily machine, I could do so confidently, but we'll see how things go in the next week.

    Hello all,

     

    I have a late 2011 MBP 15" with the discrete graphics card. I have definitely noticed the weak battery life despite trying all of the tricks such as

     

    low screen brightness,

    no keyboard back light,

    using integrated graphics card only (with gfxstatus),

    using sleep whenever possible,

    resetting SMC,

    resetting PRAM,

    applying all updates almost as soon as they come out,

    etc.

     

    My MBP came with Lion preinstalled, so I have never been able to compare it against SL performance.

     

    My battery charges quickly (within 1.5 hours with minimal use starting from about ~10% charge), but drains VERY quickly (within ~2 hours or so) when running off of battery. I am not doing anything power or graphics intensive. I have not noticed any difference between the default "Dynamic Switching" of the graphics cards, or using the integrated card only. I made a few calls to Apple Support and a visit to the Genius Bar. Neither was able to help me on this issue. Officially, this is an unrecognized problem. I was told that computers with Lion preinstalled probably wouldn't work at all if I attempted to remove Lion and install SL. The Lion updates I install have had no impact as far as I can tell.

     

    However, I did get in touch with a specialist at Apple (who, I've been told, are at a technically more proficient level than that of a typical customer service rep) who contacted me about this issue. We spoke over the phone, and he had me do a few diagnostic tests back in Nov 2011. The log files from those tests were emailed to him the same day. Unfortunately, I haven't heard from him since despite multiple attempts at reconnecting in order to check up on how things were going. In short, Apple does know about the problem at the technical side. However, I don't know if anything is actually being done about it.

     

    I have also been invited to test out Mountain Lion last week, but have declined for now. Before being a guinea pig, I had a few questions but was not able to reach a Apple specialist to answer them.

     

    I'm probably not contributing something that hasn't been said before, but thought I'd let everyone know of what I've learned during this journey... If anyone has any more information - technica or whatever - I'd appreciate it!

     

    Best of luck!

    calibrating the battery:

    I didn't think this would work because i thought it was only for the old powerbook batteries, but I tried calibrating it (letting it drain to 0% and then charging) and it seemed to actually help. either that or i'm becoming so use to this low battery that it only seems like the charge is better.

     

     

    -although i should mention one new concerning thing i've noticed:

    with my past macs i've always just directly plugged the ac adapter into the wall without any issues. with my macbook pro

    i tried plugging it in directly, without the provided apple extension cord, and when i went to reach to unplug the adapter it was incredibly hot. when i use the extension cord with the adapter i don't notice this tremendous heat.

    As per the docs, the integrated battery unibodies purportely come "calibrated from factory" and require no further action. Which sounds like someone in Cupertino is blowin smoke up our collective kazoos, cause each friggin battery is different from the rest, no matter how serialized the production line is, and I see no way the battery controller is able to guesstimate the remaining charge time throughout the lifetime of the battery unless it gets a chance to see the real deal every now and then.

     

     

    Let the Battery Wars proceed unabated!
