Q: Lion - Horrible MacBook Pro Battery Life

Strange. I don't use facebook. I'd rather spend my time in a more constructive way. And also make some cheese in the spare time. Do you want some?

Ps probably you should restart your machine in order to have a bunch of daemons log after you set them to do so (if you have done that in prefs -> privacy)

Come on relax and use a little more that right part of your brain.

Well for those trying to find the right key for a google search this can be a good starting point:

After updating to Safari 5.1.2 my battery life has doubled using 10.7.2. I notice my battery life because I'm a student and drain it almost every day. I usually have to carry a charger however today after updating I no longer need it on a full day's worth of classes. Before the safari update I got around 3-4 hours, today I clocked in around 7-8 and came home having about 30% left. The only other thing I changed was repairing the disk permissions. Hopefully it will last...

Unfortunately it'll not last that much. It will still have a drain during sleep mode.

We already miss you.

Rayced, I'm not thinking you are inventing things, but maybe you've somehow enabled powerd log writing.  I often enable or disable useful or useless processes on my MBP and then forget about it over time.

PS.  Maybe by enabling debug mode?

Coming from the world of hackint0shes (all legal of course, I also have a MBP) It might be a kext issue. Backup everything you need and reinstall macosx

Kext. Interesting. I had a problem with kext files, and I was able to fix it with Kext Utility, a free application. Is it possible to use this utility, instead of the "back up and reinstall" option? I have a ton of applications, many of which have serials or require re-registration to various sites.

I'm not unfamiliar with kexts. How would this change your battery life?

Fhsjaagshs, are you talking to me or did you just click the last reply button, because you didn't want to look for an individual case, where re-installing might actually help?

You don't even have to mention that. Try with this in terminal:

pmset -g log

Probably it'll go trough.

I also have this problem on my MacBook Air 2010. Went back to Snow Leopard till Apples fixes this issue. Any improvement with Safari 5.1.2 or Lion 10.7.3?

I seem to be getting improved battery life after upgrading to Safari 5.1.2.

However, it may just be that placebo effect again... Only time will tell.

I am experiencing a similar issue on my recently bought MBP ( Lion,15" i7, 4GB RAM, 2.2Ghz ) My battery drain is terrible, this being my first venture into the world of Mac i must say it hasn't been a smooth one.

I have installed Coconutbattery and my battery capacity is at 100%, i have also installed gfxCardStatus v2.1 to moniter  the switching of my graphics card and it improved from really terrible to terrible.

At a 100% battery charge screen at 30% no backlit keyboard, finder, mail, chrome blink accèss manager (u600 modem), safari running i would get a "solid 2 hours" before i have to charge again.

I tried a SMC reset (Shift, control, option and power no improvement, tried calibrating the battery draining it till won't power on leaving it with out charge for 7 hours charging it till my charger light went green then tried using and again no improvement.  please help
