Since I installed the most recent OS X update 10.9.2 for my 2013 MBA, my battery life has seriously decreased! I am not using my MBA any differently, after 2 hours of use the battery life went from 100% to 75%. Anyone else had this issue?
MacBook Air, OS X Mavericks (10.9.2)
1. Check the cycle count of the battery against the limit for your model. The battery may be due for replacement. If the power adapter is connected almost all the time, the battery may need replacing even though the cycle count is not too high.
2. Follow these instructions, or these for OS X 10.9 or later.
3. In the Energy Saver preference pane, uncheck the box marked
Enable Power Nap while on battery power
4. You can also try resetting the SMC.
5. Make sure your system is up to date in Software Update.
6. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.
Hi Linc,
Thank you for the advice.
My MBA worked perfectly until I installed update 10.9.2. From looking at other user questions, many people are experiencing the same problem. I have submitted the problem through the feedback form in the hope that Apple rectify this on the next update.
I have had the same issues. It seems as though everyone doesn't have this problem but many air people I know have seen a significant decrease as a result of the update. All I can say is to send feedback to apple else they will not know our plight.
