Yosemite Battery Drain

Having the same issue here, but it's not beta.

Went from 5.5-6hrs on Mavericks on a Mid 2012 Macbook to less than 3 hours, 2 if I'm lucky!

In fact, typing this alone made my percentage go down 3%.

Already checked all my running apps, and turned off widgets.

I have finder and Chrome running, and that's it.

****, even my brightness is one tick away from being completely dark.

What gives Apple?? I bought a Macbook for better battery life than Windows, and now it looks like they're competing for worst battery performance as well!

Nope, still not true. It does not matter how many times you say it, it does not make any more true. Been running Safari for the last couple of weeks and I am still having the same battery problems I had with Chrome installed. Chrome is not the problem.

There's no rant fest here other than you trying to blame Chrome. Everyone else is just sharing their problems.

And like I said in my original post, I already had my machine and battery evaluated by Apple (who deemed it to be without flaws).

"Sharing" fails to exploit this site's resources. It accomplishes exactly nothing, and nothing is what you have achieved.

Lack of knowledge may make you believe that this is the same problem but there is no evidence of that.

And it's another reason why you should stop hijacking the thread and post your own, or do you prefer to muddy the waters?

Agree to disagree. I think letting people know that Apple Support are aware and admits that there is a problem with battery drainage with Yosemite is helpful. I also think it's helpful to let people know that John Galt's baseless suggestion that Chrome is to blame is in my experience wrong. And yes I do think it is helpful that people like myself, Gollwitzer, Doctor Mesmer, benz0s, etc. etc.share their problems as I think it is paramount to getting a solution for this acknowledged problem that Apple knows how many people are experiencing battery drainage. It's fine if you want to disagree with that but at least it seems a lot more beneficial and helpful to our community and than trying to belittle people and talking about people's "lack of knowledge."

OMG. Still about that old Chrome thing? Help people and don't start stupid trash talk.

Everyone that wants help: there are many posts that show how to clean install it. I did post a detailed instruction a few days ago In this very thread. It did the trick for many, many users. Also for me. Do it. CLEAN REINSTALL OF YOSEMITE!

Dont reply to haters... They'll perish anyway.

I think it is paramount to getting a solution for this acknowledged problem that Apple knows how many people are experiencing battery drainage.

Other than having your Mac evaluated by Apple, who also informed you that Google products are a notorious cause of poor performance, you have taken no action toward accomplishing that goal. You can't even seem to click "new discussion" and provide even the most cursory details regarding your system. Any expectation of assistance is unreasonable.

I did clean re-installation of Yosemite at 8 december.

Many apps are more reactively now, spotlight is not the best, and the battery drain is always incredible.

I lost 40% duration battery after Yosemite installation. The first installation was 1 december and it wasn't clean. So did the installation again clean with time machine back up, many things are better, but battery drain didn't improve.

at which mail address can I send a claim to apple ??

why apple did this mistake ??!?!?!

Guys and Girls,

Believe me, I've tried everything, clean install, reseting etc. nothing really works.

the solution is to go back to maverick and stay with it.

maybe I don't have the calls into my mac and all those add ons , but heyyy my MBP 2013 working perfect with 8-9 hours of battery life, who need more than that?

I'm going to wait at least an year before i'm going to update to this unfinished OS.

this battery drain problem is also occurring with my macbook air 2014 model ..earlier it used to give 12-13hrs of battery life(after running 3-4 movies ,Facebook)...but now it is giving 6-7 hrs of battery life .....what to do ?....apple plz do something about it ...it seems many people are having the same issues....

I will chime in, my battery has recently sucked but has not always sucked on yosemite. I just recently noticed this poor battery life after the mandatory security update that just was sent out automatically. I too have a late 2013 retina 13 inch, and I am at 53% with only 2 hours left on the battery. This is crazy and I hope it gets fixed soon.

Again I didn't seem to have these same issues a couple weeks ago

for some reason I can't edit my post... but to update.

I was at 53% with 2 hours left, I noticed my Mail app eating up CPU so I closed it, and I now sit at 49% with 3:35 left. So perhaps the mail app is the culprit ? This may be old news...

Mail is absolutely one of the main causes of this problem. If you go into Applications/Utilities/Activity Monitor you can actually watch the Mail app push your CPU to 300-400%. The saddest part of all of this is Apple's complete unwillingness to even acknowledge the problem. If you go to their stores and press the hard enough almost all of them admit that this is a known issue.

Agreed, what's strange is that it only started happening recently and I've had the mbp for 13 months. One of my work emails got hung up and would not load,and ever since then I've noticed the problem and when I force quit the mail app that email still hadn't loaded.... There were no attachments either. I bet that its getting hung up on certain messages and killing the CPU.
