Configuring background app refresh

Hello - when configuring phone settings to enable sensors, one of the recommended steps is enabling background app refresh (settings > general > background app refresh). The two available options are “Wi-Fi” or “Wi-Fi & Cellular Data” . Is there a difference between these two options in the actual quality/quantity of sensor data collected? Which would be recommended for optimal sensor data collection? Thank you!

We would recommend WiFi & Cellular Data! This seems to be a new option with iOS 15, so our team will update the documentation to reflect that. Thanks for bringing this to our attention!
