Mavericks MacBook Air 2013 Battery Draining

Update: As of now my battery health is at 98% and the time remaining is showing 17hrs 😝, is this accurate? lolz...

same here. my battery seems to be increasing as well, but it's still much less than that it should be. at 100% it had 5:52 remaining, at 85% (80 minutes later) I have 6:54.

At that rate you will have about 8 hours remaining when your battery reaches 70% charge in another 80 minutes.

Wow, the shift+control+alt+power (three times) worked on my MBP late-2008. Still shows service battery, but the Full Charge Capacity increased from 1400 to 3600. It's not too much, but much better, because i've only 124 cycle, and happened after installing Mavericks to a secondary partition. Thank you.

do not download etrecheck from any other site than www.etrecheck.com......

Would the safe site be:

www.etresoft.com/etrecheck

www.etrecheck.com

says it can´t find the serever.

NO the site is: www.etresoft.com , the app is Etrecheck.

I mistyped, sorry.

What I meant to say is, that you never know when you download apps from a non-developer site, there can be an "info" trojan in it. Like the CNet sites (according to a very well known "helper" here who has specialized in security).

Your Mac sounds beast!

Same problem, but mine isn't as dramatic. I lost about an hour on my 2011 MacBook Air i5 64GB Storage 2GB RAM. Used to be 6-7 hours, then dropped to 4-6 hours with new update.

I just did, twice. Had under 3 hours battery life with 10.9.1; restored to a previous version, battery life went to 8 hours plus. Updated to 10.9.1 again, battery went to 3 hours. Finally, I'm back to the earlier version and - low and behold - battery life eight hours. That is more than enough proof for me.

As stated much earlier, in some instances with Mavericks on the Air the time remaining estimate from Apples A.C. system is reporting wrong 'remaining'

this however has no affect on actual battery life.

This is known and being looked into.

happy new year 😊

I can now report using coconutbattery. Facts:

- upgraded right when 10.9 was out.

- MacBook pro '09, all original

- at upgrade under 150 cycles, original mAh is 5450, it says age is 55 months (???)

- typical use email, banking, payroll run, Skype, hot and humid climate (south east asia), no backup option = no clean install

- occasional Excel for some finance booking

- took me cca. 3 weeks to do something. go figure but past Thanksgiving it started regaining what it had before

- updated to 10.9.1 yesterday (have some internet connection) as the last day of the year

while typing it say over 4 hrs remaining, I usually take 2-3 hours on the laptop, then let it charge again. My habits do not change. I lost some 200 cycles, but I think that is mostly me trying to SMC/drain/SMC when I was in panic.

Now it seems normal, I lose a cycle every 3-5 days but that may be okay, the battery is not new.

I say patience is a virtue. It had to be some background procerss. I even installed and ran Onyx, in case my MBP wanted to index something at a wrong location (old school thinking) but thta made no diff, not better, not worse.

see the last bad cycle was 341st. after that it went back to 83-84% of the original capacity, so no service sign any longer. I think it will live for another year (at least).

youre reporting that on a Macbook Pro 2009 with coconut battery app?

Specifically in this instance as per the Macbook Air (same implications as per lithium batteries),....

A: cycle counts dont account for anything, any more so than does the odometer on a car indicate abuse /wear / tear.

Its meaningless if incorrect, just as an odometer if incorrect.

Its also a giant myth that genuine cycles = X wear on a lithium battery, while true that moving Lithium Ions from kathode to the anode induces chemical alteration over time, reducing charge capacity slowly (in ideal use conditions), its a complete and utter myth that X number of charge cycles indicates anything in specific,

and factually it also means nearly nothing at all in general sub-500/600 cycles. 😊

B: Coconut battery gets fed the same stats from the same place as the resident battery monitor, only it gives a bit more information. Both are just estimates, and if there is a glitch in the reporting, both will report the exact same time "remaining" , either accurate or inaccurate. The only diff. is coconut posts mAh.

C: you havent "lost" a cycle, its being reported incorrectly, there is no magic cycles = use/abuse/wear/tear

😊

In addition to Plotinus:

55 months is correct (4.5 yrs), why did you add "(???) ".

Cycle is counted as follows: everytime you are off the charger, you loose a part of the max capacity; everytime when these "parts" counted together are equal to the max capacity, a cycle is counted +1. Thus if you three times have 1/3 of the capacity on battery, a cycle is added, and so on.

It looks to me that your battery is happy...

My late 2013 model Mac Air's battery drained fast. I uninstalled Google Drive per Apple wich helpd some but not 100%.

I finally figured out that if Apple's earpods are connected to the computer, without listening to music, it will drain the battery for some reason. I now unplug the earpods and my battery is 12-15h.

Hello everyone.

I have a 2013 MBA. After downloading Mavericks I noticed my battery was draining when I wasn't using the computer (in sleep specifically). Additionally, I was only getting a max of 3 hours out of the battery (probably closer to 2 on a full charge). It was really frustrating.

I browsed the internet a bit and most consistently read that resetting the PRAM and doing a disk utility repair may help. Instead of waiting for Apple to come out with an update I went ahead and gave this a try. Now my MBA is back to having >10h life (which is normal/fine for me). Feeling very relieved.

Here is specifically what I did:

1. Disk utility repair (apparently youre supposed to do this every couple months). Disk utility is under apps btw.

2. PRAM reset (http://support.apple.com/kb/ht1379)

Hope this helps some of you out there!
