Any fixes yet?
I just bought a used 2013 MB Air running 10.10.5 with a brand new battery replaced by Apple ( only 3 cycle counts on it ). Like everyone else reporting here consistently since 10-17-14, you can watch the batt. % drop with nothing open At All. This machine has Apps installed but nothing running. I have not added any of my data yet (no migration). Has anyone yet found out a fix to this yet. The majority of posters show no issues in their etreCheck reports, but since upgrading to Yosemite (and going to El Capitan did not fix the issue for a recent poster here) battery life has dropped to 1/2 (or less) of what everyone had just before upgrading from Mavericks.
From CoconutBattery: battery Mfgr date 8/1/15 After charge to 100%: Full Cap = 7474 mAh, Remaining = 7474 mAh, Design Cap = 7150 mAh,
After unplugging 97.9%, battery usage 4.4 watts
After unplugging... System says 100%, 14:01 remaining, no apps using signif. energy
My EtreCheck report for the record.

One of the reasons I chose a 2013 MB Air was because it was supposed to have much better battery life than the 2012. I never saw any caveats say this ONLY applies to specific OS's (Mavericks) and to avoid Yosemite and El Capitan.😕
