Q: Lion - Horrible MacBook Pro Battery Life

You can do a fresh installation of SL by using the CDs that came with your MacBook.

As for Lion, you don't have to buy it again but if you go to SL, you will have to download it again. If you have saved the lion installation file, here is what you can do:

Locate the OS X Lion installer and right-click on it. Select 'Show Package Contents'.

- Inside the 'Contents' folder, there is a 'SharedSupport' folder. Inside that is the Lion Installer. It's called 'InstallESD.dmg".

- Copy 'InstallESD.dmg' to the Desktop by clicking and dragging it while holding down the Option-key. You should see a little green plus icon if you did it right.

- Open Disk Utility. Head to the Go menu in the Finder and select 'Utilities'. Disk Utility should be in there.

- Click the burn button.

- Select 'InstallESD.dmg' from the Desktop, insert a blank 4.7GB DVD and wait. Once it's finished, you'll have a shiny new Lion install DVD.

You can now install Lion on whatever machines you like, just as if you'd purchased the install disc from your local Apple Store. Lion is expected to launch on the Mac App Store this week.

I followed you up until this part...

I don't know if it was 8 or 10, but it's 2 or 4 now. I use it for work, so I do the same stuff on it all the time. This is a bug whatever it is, and it's actually burning power somewhere and "top -o cpu" isn't any help.

It's an unattributed cut and paste from MacRumors.com

You are right John. I should have mentioned where this piece was taken from but the problem was I forgot the website because I saved long time ago on a word document (I didn't save the link, just the contents of the page). I simply copied and pasted from that word document.

However, it worked for me and now I have two DVDs and one USB of my Lion.

Something weird just happened. I was reading a webpage. The estimated time on the battery was 1:35. I left the computer for less that 15 seconds, the estimated time on the battery jumped up to 2:55. Is that possible?

That SHOULDN't happen but you are not alone!

but i downloaded Lion from Ap Store. I have no idea where it stored te file. How do i choose the location where i want to store the file when i download from Ao store. Also i'm not worried about downloading lion again, only concern is i shouldn't be paying for it again, considering what crap they have sold me the first time.

I'm going back to SL, see you soon lion...

You downloaded Lion from the app store, this means that it is an application. It was in the application folder when I downloaded it. When it started the automatic installation, I didn't click anything until I copied the file to the desktop. I made a lot of changes on my MacBook (downgraded to SL then upgraded again to Lion just to make sure that Lion is a huge mistake that has some cool features) so it is not there anymore and I am not sure whether the installation file stays in the application folder. Check it.

Yes.

What you have to remember is the time remaining for your battery is only an estimate, based on your current energy usage.

So for example, if you run something very CPU-intensive, you'll see your battery time remaining drop to a verly low level, but if that process completes, you'll see your battery life remaining timer go up.

Because of the way batteries work, the timer will also get more accurate as you get nearer to 0.

Forget about all these fixes.  Snow Leopard always ran on the discrete graphics card (menu item started at login) and loads of processes (same ones) and applications open and still lasted at least 5 to 6 hours.  Now with Lion all I get (with the same medium heavy use) is slightly over 2 hours (without discrete, etc.).  What use is it, if you are not meant to run anything on battery power?

I agree that Lion has some very nice features, but at the moment it looks like it's made for Desktops (although MacBooks are the main seller).

MacBook Pro (early 2011), Lion 10.7

What is Mr. Jobs thinking about? People who use MacBooks are more than those who use iMacs. Besides, the main reason that people buy MacBooks is the battery life and then the reliable operating system (I mean SL). Lion kind of destroyed both features. MacBooks are now worthless.

This morning, I decided to monitor my battery (disregarding the estimate reading on the battery capacity). It lasted exactly 3:50 minutes (which means that I lost 50% of the battery life).

I still believe that the operating system is reading the battery wrong.

Finally gave up on Lion and reverted to Snow Leopard.  I'm in an office full of Mac users and I was the guinea pig.  I helped a bunch of guys avert the issues and problems I faced.  Too bad.  This is my first Apple computer in over 10 years and I thought Apple was something better than Microsoft, but now I see they are just the same, just packaged differently.

I don't blame you for feeling this way. I'm a lifelong Apple user from the 80's. Lion is disastrous as far as I'm concerned. Broken software; instability; odd functionality; dumbed down interfaces; hidden files; and of course, it's bloody hard on the hardware.

I'd go back to Snow Leopard in a nanosecond, but I can't find a way to put it on this new laptop. Lion is a sickly kitten, and it needs to go back to the vet.

i think you're right i test without any program running and wifi off (closed lid):

and with wifi on and safari running (closed lid):

maybe i can conclude for now that i don't have problem with the battery in lion

though with time & more testing we'll see

thanks LexSchellings!
