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

I love my Android devices (Lenovo Pad and Samsung GS2), I love my Mac with two Lions, I love my Lenovo T420 and Lenovo X300 too and really don't feel that I need your assistance.

Bob, Csound, Rayced, Franc and a few more regulars on this forum, I have not a single doubt that you are very passionate and technically advanced computer enthusiast (or pros) but I'm getting feeling that some of you struggle to get in touch with reality!


C'mon guys, move on! I'm sure that all of you know that Lion is history, the end, kaput, fin, dead, especially since Mountain Lion has been released (dev)!


For me this experience will be a very good lesson to think twice before I open my valet next time in Apple store.


PS I installed today Mountain Lion and........................................ not sure what to say since I'm android user who personally give s#1t for iPhone/iPad!


Mountain Lion is gonna be based on Lion. And you can stick with your Android devices if you feel better using 'em.

It seems that battery performance if very similar, almost identical. With almost the same apps open (Chrome, mail, iChat, Finder, Sophos, iCal and Qucksilver) and the same brightness I've got on both OS reading around 5.30 (+/- 5min) on 88-90% of charge. I compared them only 3 or 4 time for the past few days, very lightly and result should be taken only as rough indication what we may expect in the future.

Great. So how is it going with Mountain Lion Beta on your MBPro? Any battery drain?

Have you ever tried to dump Safari's cache and get rid of Google's cookies in Safari, than check your battery estimate time.


What do you think about it?

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.

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.

Never tried, I might give it ago!


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

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.

That's not so planet friendly…

Feb 23, 2012 12:42 PM in response to Rayced

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.
