Lion a battery hog?

This thread has some people with similar issues. You are not alone on your observations:

Its killing mine also. My computer was a 94% when i went into a lecture 35 minutes ago, and it is now at 68%. Its a new macbook pro.

I have a mid 2009 MBP 13" an my battery life has dropt also. so hopefully apple will make a fix in lion so we can use our macs normaly again.

Same here. Looks like securityd process is taking up 89% CPU all the time when Mail.app is open. Quitting Mail eliminates the problem. But that's not really a good workaround...

Lion is a fiasco so far
My Macbook is 3 months old
Battery life halfed
My lap is on fire

Such a blatant issue should have prevented this from being launched
They clearly knew about it and are using the consumer
£2300 I could have bought 7 Dell !!

as the guinea pig

Apple come on
Get that update done........

Same here. I have a 2010 15" MBP 3.06 GHZ 500GB 7200 RPM 4 GB and was getting 4 hrs of battery life on a full charge (with optimal performance settings, not better battery life) with Snow Leopard. With Lion I'm getting 45 minutes to an hour on a full charge. I hope there's a fix soon.

same here

I have the same problem with a 4 month old MacBook Pro and the battery only lasting for a couple of hours, but your problem with securityd is something else. I have Mail full screen running and securityd is on 0% CPU, 4 threads and 7.0 MB of Real Memory. I'd check it out, should be solvable.

Yes it is lion mail and it drives me nuts, you have to completely quit mail for it to work correctly why is it using so much cpu? It is definitly unnecisary. When mail is open my Macbook Pro's fans are constantly running and the cpu temp is usuially at 175 Faraneight and it gives off a slight smell of the hot components. Along with the fact that when I try to close it it doesn't go to sleep it runs at this temp all night with the fans blairing. PLEASE FIX THIS APPLE!!!! SOOOOON!!! And it takes up so much battery life it also seems to do it in cycles for 30 minutes it will be blairing then it will stop for 5 min then do it again.

I'm having the same issue - after upgrading to Lion (i did a total clean install), the battery life on my macbook pro 13' 2010 has reduced significantly - now only showing c3hours left after I disconnect the magsafe (it used to be 5+ hours). I already tried to reset the SMC, which hasn't helped. I don't understand why it takes more electricity to do the same things previously in Snow Leopard.

Same here, I'm getting a maximum of 3 hours battery life, and that with very light usage (few light apps, light webbrowsing). I have a brand new MBP 15", 2.2 Ghz Core i/7, 8GB RAM, 500 MB 7200 rpm, - please get that update out!

I just posted about this in another thread earlier this week.

I just got my macbook pro 13" in early July. About a week or so after Lion came out, I upgraded to it.

Before Lion, Snow Leopard had 8-9 hours battery life. Was cool running and super fast. A full charge would last me aprox. 3-4 days and that was surfing the net, playing fb games, doing the ebay thing, etc.

Once I installed Lion, I get aprox 3 hours battery life if I am lucky. Last night I had it plugged in. I unplugged it and was on the net for 10 minutes, my battery was down to 93% already. It dropped another 8% while in sleep mode while I was at work. I have been on now about 20 minutes and am already at 74%.....It runs much hotter than it did before also. Plus I notice a significant drop in web browsing speed as well.

I am planning to go back to Snow Leopard. I am tired of the poor battery life, hot running speeds and slow web browsing. My Mac after the Lion upgrade is now Windows-Like and I hate it. I bought the Mac because I felt it to be superior in quality to any of the windows based computers.

I SO Kick myself in the Butt for upgrading to Lion........So far, it has basically ruined my $1300 computer and I am a little more than ****** about it. I find it really hard to believe that Apple did not know about this, They HAD To Know, and released it anyways.....Shame On YOU Apple !!!

Note that: Upon launch, for the first 3-5 minutes, securityd stays low in my case. Just after that time it starts "working" and takes up significant CPU cycles (whatever it's doing. a quick look at the sampling in Activity Monitor seems to indicate activity on message attachments, but that's just a quick look).

Other note: Since 10.7.1 the problem has in fact vanished on my Mac Pro, but stayed on my MacBook Pro - where it is still the same. My idea is that some old/broken SSL certificate or CA is triggering this, but I wouldn't know which one or how to find it out. Other people with similar configurations do not have the problem, so Apple might be having trouble reproducing it, but I'm happy to see that I'm not alone...

Hi everyone,

I just purchased a 2011 MBP 15" 2.2 GHz (with the integrated and discrete graphics card). The laptop came with Lion preinstalled (I have never owned an Apple product before this) The quick battery drainage was apparent to me from the start, even with crumby YouTube videos. I called up Apple Customer Service about this. It appears that the graphics-switching overestimates graphics needs for much of the time, therefore using the power-hungry discrete GPU unnecessarily. The representative did tell me that a fix was being worked on. I asked him if this was just "theory" or was it actually in the works. He told me that the graphics card engineers were working with Apple to correct the problem. A fix should be out "in a few weeks". Keep your fingers crossed.
