Yosemite Battery Drain

Since installation of Yosemite on my late 2008 MacBook my original battery has died. Maybe it was time, but it was holding 2.5 hours when the "service battery" message appeared. I have installed a new battery with little improvement then did the 10.10.3 upgrade. One cycle into it I now hold approximately 4.5 hours of charge. We'll see if that improves but I think I can live with that. No messages and functioning at 100% according to the top menu bar.

Since yesterday I did the update I am having problems with my battery on my Macbook Pro.

My battery lasts less than an hour now when before lasted 4h30min!

Apple will solve this problem fast? I hope so, if not my work will become almost impossible to do ...

So I'm not the only one who is experiencing very unusual battery drain at the rate of 1% per 4-6 minutes.

It only started after the last update. I do remember during the installation or during one of the reboot cycles seeing a message about "optimizing" power or something like that.

I hope there is a fix for it and SOON!

Please Apple 🙂

me too. The best advice for people with yosemite problems is to go back to Mavericks. Yesterday I was able to watch 2 complete soccer games through wi fi at 95% brightness. At the end i had 65%. So I am not going back to yosemite + I like how Maverick looks.

On my retina MBP 13" I hadn't problems before 10.10.3, it appear with this new update. Battery draining fast, overheating and variable battery charge time remaining. The Genius reinstalled me Mavericks, but the problem seem not be solved.

Mate, I had the exactly problem. Reinstalled Mavericks and the problem was still here. The solution was opening the mac, disconnect the battery connector from the logic board for 1 hour and then connect it again. By the way, I had to give this solution for the Genius bar! Apple is being completely incompetent in find a solution.

That would be a good experiment; I recall several users on this thread who wanted to try but we never heard any feedback. I wanted to but I don't have the proper tools nor the time to try...

Anyway, if anyone feels like trying, iFixit has the tools and they provide guidances : https://www.ifixit.com/Guide/MacBook+Pro+13-Inch+Retina+Display+Mid+2014+Battery +Replacement/27832

I tried disconnecting the battery for a little over an hour earlier today after reading the previous post. I'm on the latest 10.10.3 update and I don't see any difference after doing that. I was actually getting better battery life on 10.10.2.

I somehow got my battery life back on my rMBP 2014 13", now running OS X 10.10.3.

For a couple of weeks I've been running Maverics on it after all that Yosemite battery fiasco, but since it's not my main computer, I've decided to try the latest Yosemite update.

I wasn't really expecting anything, so I didn't bother with a clean install, and instead updated straight from Maverics.

What do you know, the battery life seems to be back to normal after the update (roughly 10 hours of mixed usage). I'll still be monitoring the issue though, since no release notes mentioned anything about battery and there is no single solution (if any) to the problem in this and other threads.

Looks like my rMBP is back to normal after doing a clean installation of Maverics and upgrading back to Yosemite, but YMMV. There is no single definitive solution to this problem and what works for me, won't necessarily work for you.

I also have a late rMBP 13" and my battery life is terrible after Yosemite. I've also tried a clean install and it's the same regardless. Virtually nothing running in the background, backlit keyboard off, screen brightness typically on 50% or less and I went from a consistent 9-10 hours to 4-5. This is ridiculous.

My advice: Take off Yosemite e put Mavericks back, with a clean install. Additionally, I unplugged the battery cable from the board, left unplugged for 1h and then I put it back. Worked very well and I had my battery back!

In my case, I lost a brand new battery. and because it was not an Apple Battery, Genius took it off and I shall buy a new one. problems started with Yosemite installation but they did not accept to take responsibility.

Yes, they are not taking the responsability truly, and I don't think they will at any time. Apple has this "thing" about claim itself responsable for any kind of error. The official assistance here in my city (Brasil) sent me back my MBA saying they didn't find any kind of problem with my baterry duration... so you can see how bad they're getting around with it

They just don't care anymore. Not about their computers at least. I have had this feeling for a while now and this experience with my latest Macbook Pro I got last fall just proves it. There is clearly a problem here but but I and other Mac-users get just sold lies by Apple employees who baseless blame the problem on things like Bluetooth and Chrome. I bought my first Mac Pro almost 15 years ago when I was 21 and I've bought a new Pro machine every 2-3 years ever since but this will probably be my last. I cannot even take my brand new "Pro" laptop on my regular L.A. to New York. work flight because my battery won't last the 5 hour flight even if all I have running is Pages. Instead I have to bring my almost 4 year old Lenovo. The Lenovo's battery started to cave in on me recently but all I had to do was to replace it and my battery life was back. With my Macbook Pro, I go to the Apple Store and I get told there is nothing wrong with my machine even if, with only Pages running, I get a life of less than 4 hours. It's been seven months, Apple are not going to do anything about it, we might as well close this thread.
