Looks like i am the only one getting worse battery on Mavericks than mountain lion. i am getting about 4 hours compared to around 7 with ML.
Nope! Me too. I went from 13 hrs with Firefox running on 2013 MBA to barely 8 at 100% charged. down to 6 hours at 85%. Nothing changed but the OS install while on AC power
What can I do? This SUCKS
