Q: Lion - Horrible MacBook Pro Battery Life

I called Applecare to let them know about my battery life reduction. The rep said he had not read or heard of any battery issues with Lion from corporate. You guys having issues should also call and open case numbers just to let them know that this is a legit problem.

I did try SMC and here is what happened:

The first reading of the battery after I restarted my computer, it gave me a reading of 11 hour battery life. I think that there is something seriously wrong with this MacBook.

My MBP was running hot, and if not plugged in I guess the battery life would be reduced from normal.

So I looked for processes using CPU.  SystemUIServer stood out at about 14%.

So I killed it.  It restarted and is now less than 1%, which is in line with my SL Mac.

The MBP is now running cool.

I apologize if someone else has posted this workaround, but I didn't want to plow through 24 pages of posts

Be assured, I too had the same thing happen after a recalibration under Lion. Mind you, after about 5 to 10 minutes all settled back to about 8.5 hours runtime. Yes, something is amiss in the Lion coding - my opinion. Let us hope a fix will come soon.

Given Lion's present condition, I'll take the developer's beta. Where is it??

Same here. Apple is sending me a new laptop. My concern is that if Lion is actually wrecking batteries, this will do no good. However, I assume that batteries are covered under the first year, if not the full 3 year apple care warranty? Hm. Maybe not...

I have the same problem, the battery in Lion (3 hours maximum).

Hehe yeah, a lot of people are reporting that they did something to 'fix' it, i.e. uninstalling some software or disabling some services or even reinstalling their whole OS- and battery life has jumped to 10+ hours.

Hate to break it to the dreamers, but NO mac portable lasts that long. Even two-bit netbooks don't last that long. It's just another manifestation of the same bug, in the opposite direction. I don't know if this is better or worse; on the one hand you probably won't 'run out' of power after 2 hours, but on the other hand it might not realize it's running dry when it actually is, and it'll just turn off with no warning when that happens. That could be really bad.

I've tried everything above:

• recalibration
• SMC reset
• killing processes
• repairing permissions
• and everything else listed above

There is no change in battery life which is under three hours. And that's doing nothing but browsing and email (new MBP, 17", 2.3 Ghz, 8 ram, 7200 drive).

I'm afraid that we all are screw up with our batteries. And i'm afraid that Apple won't do anything to fix it.

Lion = Windows Vista

The next year we will see the Mac iOS Lynx, Persa Cat or something!

Consumerism...

Mannaggiallamadonna!

Same issue here: MBP 15" 2011 i7 2.0Ghz 8gb, with Lion I get 4hrs max when surfing the web. (luminosity set at the second bar)

Son of Jobs

Is there a way i can go bacl to SL and later install Lion. I downloaded lion from App Store and updated SL. I don't have a lion on a disk. If i go back to SL will I have to buy lion again.

Help on:

1) How to go back to SL?

2) Lion on app. store?can i make a bootable disk now?

I am fed up of the battery drainage. It has come down by 50-60%. I have few tricks as mentioned here, but of no avail. Some help here!! ONe big reason i like apple is that it used to give 7-8 hours of battery life., now its less than 5 hours on good days..!! arghh...

TIA

I'm an iOS/Mac Developer, so I can see the differences inside.. The problem is that after some time you don't really remember how was a pain with windows, especially if you work 9 to 14 hours a day with your computer..
