Percentage of Battery freezes in OS X mavericks

I am having the same issue. I charged my Macbook Air to 100 percent and it was still plugged in with a green light on the charger chord. I opened up the computer lid and the battery on the lock screen was correct, but when I logged into the desktop, the battery said 95 percent and didn't indicate that the computer was plugged in and charging. Please help!

Appleprodcts, I too am having the same issue as you. My MacAir will hang at different battery %'s, the most recent was just then, when I was wacthing a video, for well over 20 mins, and my battery remained at 48%. I put the computer to sleep and instantly woke it back up and the battery on the login screen showed 31%. BUT when I logged in, it went back to 48%. Definitely Mavericks, never had this problem until installing this OS. Upon writing this, the batter has corrected and has commenced its decent, still very frustrating.

I second this problem. My MBP started doing that same thing this week, after I installed the SMC v1.2 update (from 12/3/13). I had already installed Mavericks the day it came out without this problem until now.

Hi there,

Is this still an ongoing issue? I've experienced the same with a brand new MBP which is totally fresh, nothing installed on it at all - I posted about it here:

Hi,

Just reporting to say I have the same issue. I have identified the issue - it occurs when I am rebooting from Windows Bootcamp. When back in OS X, my battery % is stuck on one value (as the battery drains normally), so I will sometimes see my battery at 100% for a while and then suddenly shut off.

I have a 15" rMBP on Mountain Lion running Windows 7 Boot camp. I also have Parallels to the same Boot camp that I rarely use.

I have this problem also!! I have MBA and recently it stopped updating the percentage unless i dusable and then enable the percentage view !!

i noticed this problem after i dwonloaded "microsoft remote control" and "parallels" donno if this has anything to do with it.

AND it also wont calculate the time remaining anymore !

hope apple fix this soon cause it's very bothering

I've also been having similar issues.

The other issue I've noticed is the Date and Time on the Menu Bar disappears sometimes when you wake up from sleep or a few other scenarios as well. The work-around for this is I change it to View as Analog and back to View as Digital.

I am having the same issue, the lock screen seems to be displaying the right percentage but the desktop is not. I am running a 2013 macbook air 4gb ram

I am also still having the same issue - on a late 2011 Macbook Pro, the battery percentage (and time remaining) is frozen from when I log on

Best way to resolve the issue, is to first shut down the laptop/pc, plug in the charger and then press and keep pressing the control+shift+option+power on buttons together till the colour onthe LED of the charger changes.. Switch on the laptop and thereby the problem shall be resolved...

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.
