10-15% CPU usage even nothing to sync, draining my laptop battery

New member | Level 2

Hi Dropbox support & friends,

I just installed Dropbox on my computer yesterday, and using Smart Sync (Online Only). But notice my laptop battery drain fast after installed Dropbox.

As checked, Dropbox seems using CPU sometimes even not syncing files. Please check below screenshot for more information.

Dropbox version: v74.4.115 / I just installed Dropbox on yesterday, I am not suppose to reinstall it so often.
