Mavericks MacBook Air 2013 Battery Draining

For what it's worth, I too was having the same problem. And I also tried to reset the SMC. And I didn't work for me.

But based on how many posts I saw suggesting this as the fix, I decided to try it again. The second time I tried it, I held the keys down longer, and it worked. I'm back to awesome battery life.

1. Shut down the computer.
2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time. Based on something someone else posted, I held this key combination down for 10 seconds. During this time, I saw the light on my magsafe power connector blnk.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.

This is day 6 and my battery is still draining very quickly! I get about 2 to 3 hours per charge. Also, the app showing significant energy usage is Safari--the only thing I have running. Any suggestions are appreciated.

Hello,

I have the same problem. I bought a MBA on July, 2013. With Mountain Lion I had between 9-12h of battery, but with Maverick (I tried with update and also a new install) I have 4-6h.

It's strange. I went back to Mountain Lion because I do not like this behavior and I prefer more hours of battery life than new improves.

Thanks

@Jask05 Did it help to go back??? Because I read of some people who went back to ml but still dont have the battery life they had before with ml.

About me: Macbook Air Mid 2013 13" --> after upgrading to mavericks really bad battery life 😟

all tips followed..nothing helped.

Interesting article:

@Christosteron Well, I think so but I've installed it again yesterday, I hadn't enough time for test it.

I hope to have any idea about de performance of ML in a few days . When I have more information I'll post it.

I hope Apple could fix this issue because I can't see these "big" improve about battery life and. I've read a lot of different topics about it and without any fix.

Thanks for the article.

Regards

thank you. because im really thinking about going back to ml, too. i dont see any good in mavericks yet. i updated because of the 15 hours battery. instead it got worse..... 😟

please tell me how it is back on mountain lion.

Cheers

Hey mts74656,

My case was just like yours. I bit the bullet and tried the SMC reset a second time holding down the button combinations for 10 Seconds and it worked like a charm.

Battery readings jumped straight from 4 hrs to slightly over 6 hrs within a boot cycle.

Thanks

Well done MTS.

I had also carried out an SMC reset, but I just tried aagain using your 10 sec press. The only difference to you was it went into a boot up as opposed to me having to power up again.

However the good news is that it worked, maybe not all the way, but I am now upto 6 hrs with 30 mins left. Suggest everyone try it, though can probably guarantee that it will not work for everybody.

I have a MBA mid2011. I've tried the SMS reset twice--still draining 1% per minute it seems at 79% I have 4:09 remaining. This is worse than it was with ML and that wasn't good. As I type this it stays at 79% but drops to 3:53 remaining. At the moment says no apps using significant energy, I only have safari with my google mail and this page active. Most times it says that Safari is using up significant energy. Very dissappointed with Mavericks and this battery issue. Haha--now at 78% and have 4:10 remaining. Very strange...wish I was more tech savvy

Right now I'm using ML and installing a game from Steam (Bastion), surfing with Firefox and bit more and I have 81% of battery life with 9:44 hours of autonomy. To me it's fine , what do you think?

Cheers

How does one go back to ML? I just got 4 hours out of my full charge today. This is not good.

See this ASC User Tip:

How to revert OS X back from Mavericks

You have two options:

1. Download or buy ML
2. I don't know if this way it's a good idea, but it worked for me. I've deleted the disk partition and when I started I had to write my wifi's name and password. After a few minutes (5-10) I could see differents options like reinstall S.O., disk utilities, etc.

In my opinion the best way is the first, but if anybody has a better way, I would be very grateful to know it.

Reseting NVRAM and SMC is the right way. I have 15:00 and more when surfing and when I watching to movie I have about 11 hours on indicator. Brightness on 50 percent (automatic controll of brightness is turned off).

What is and how to reset NVRAM?
