I&#x27;ve had a similar experience.<p>I&#x27;ve never noticed a problem with Dropbox. Of course, I&#x27;m not running tools that show me battery consumption of apps and such on my Mac. Battery lasts long enough that it&#x27;s never been a problem to look into.<p>I also had trouble with early versions of Google Drive. Maybe it&#x27;s time to give it a try again. The problem I had was that drive thought all of my files had changed every day and started syncing the entire Google Drive folder again. I removed it and haven&#x27;t tried it again since.
