I am on Windows 10 and suddenly having the same CPU usage issue as well since the last few updates.... I have a 12-core AMD processor and the evernote process is consistently using 5% of the total available CPU power, even at idle / when minimized. Tried logging out / logging in, restarting the app, restarting pc, etc. The issue remains. I am on the newest version. Please let update here if you resolve this CPU usage issue. I also opened a support ticket with evernote, and included a log export. Hopefully we can figure this out
