I use the app occasionally, and it&#x27;s only used 2% of my battery on average over the past 7 days, according to the battery section in my settings. I turned off background refresh.<p>Strange that the author is going through a guesstimate process when there&#x27;s a built-in tool that&#x27;ll tell you exactly how much juice an app uses, and if it&#x27;s mostly from background activity.
