Mavericks MacBook Air 2013 Battery Draining

Hi,

https://discussions.apple.com/thread/5563425

I got 4 hours last night and about 5 hours this morning. Just plugged in now at around 10%. not entirely unsatifactory, but not at all close to what I was getting before Mavericks.

Hey Lex, This is a new thread I started as advised with etrecheck and rember tests.

Found you, but another NEW thread is not necessary: go on in the last one you just made.

I don´t think it´s the mail app either.

My Macbook Air is about three weeks old.

It came with Mountain Lion form the Apple Store and it had about 94% charge out of the box.

I assume it had been sitting at the store for a while since it is not a new item but rather kind of mid cycle.

It´s not like they are moving constantly like iPhones 5S´s or iPad Airs.

Battery was working perfectly and would not drain while sleeping with lid closed.

Since updation to Mavericks the battery loses about 2 - 5% over night in sleep mode withlid closed.

When it is in use you can see percentage coming down every 3 to 5 minutes

Yes. Battery is draining way to fast with this new OS upgrade.

Mavericks seems to have some issue.

Hope they come up with a fix soon.

I found a fix! whoever knows how to reset the smc (http://support.apple.com/kb/HT3964) follow the controls to do so. Instead of holding the keys for 10 seconds, hold them for 20. following that, repeat this 2 times then press the power button. I did this and my battery life has increased so much that i can last around 4 hrs browsing the web at 40%. to summarize this easily, reset the smc multiple times before you push the power button. also, hold the key combo a longer amount of time then apple suggests.

Well would you believe it, I have been on this thread from the beginning, battery down to 3hrs on my 2013 11" after Mavericks, nothing really worked, just went through the above procedure, and now I am back to 8hrs.

Thanks macmacma, proberly will not work for everyone due to the nature of the beast, but it did for me.

that's what i did and your welcome

Is the battery drain problem happening to Macbook Pros too?

Or is it only happening to the Macbook Airs?

i read that it's happening on many laptops- just read my answer and it works on all macs that i've tried. post a new thread if it doesn't work, 'cause this one's getting long

macmacma...

just read my answer and it works.....I found a fix! whoever knows how to reset the smc.......... reset the smc multiple times

No, not true at all, nope. Not one bit. 😉

Ive tested multiple machines and did that long time ago, does not work, however it WILL display correct time remaining for a while, usually until a high energy tasking APP is activated.

Good try, but no, its a software fix that will have to be implemented.....that multiple SMC resets wont solve. A for effort.

There is no point in putting out a blank statement that it does not work when it obviously does for at least two of us.

Before I carried out the multiple SMC I was getting barely three hours, now I am back to the eight that I had with ML on my 11". This is timing against a clock ruling out any figures from the battery icon. However even that is behaving now with %, and time remaining agreeing with the clock.

I appreciate that you are not getting the same results, but that agrees with the overall picture that the majority have had no problem with decreased battery life, but a fair % have.

good for you. I have been disillusioned by the responses like yours (and turned away, as if having a problem was my sin). This is a forum to discusse issues. if you have none: great. Don't bother responding. If it does not work for enough consumers then it does not work.

I do and seeking for a resolution.

I recorded some steps but cannot seem to paste it here.

let me try again: also, I am aware my machine is old (2009).

Nov 11, fully charged for couple of days, letting battery down (calibrating)

quitting Mail

(original charge was be 5400)

restarting Mail

(letting it drain)

Quitting Mail again.

interesting jump (red color) to the next cycle

and this goes on. The battery dies in roughly 30 minutes. One cycle is lost, or 2, depending on the cycle counter, at re-booting the other. One occasion took several dozens, thus 342 (started on 147, not recorded).

Not much changing until battery is completely off. Full recharge and rest will follow, to calibrate. Not expecting improvement.

Nov 14, 2013 (after calibrating)

Starts okay:

but it will quickly go to the same cycle, after starting Mail, could that be the issue?

even worse: on Nov 18 (after not using the laptop for long but keeping it charged) the battery showed around 65% when all of a sudden the MBP went sleep. When restarted (plugged in) this battery shows 0%. So there is no recognition of the battery level.

Hi Salf,

Can you please write the quitting mail fix in more detail as I cannot see your image. Please please...Been trying to get this issue fixed for weeks now...
