A. 1. Go to your iPhone's Settings, scroll down to the EcoNet app, and ensure that Background App Refresh is enabled. 2. Check if Low Power Mode is turned on; if so, disable it to allow the app to run in the background. 3. Restart your iPhone to refresh all running applications.

B. 4. If the app still does not run in the background, consider using the app more frequently to keep it active.
