1. Continuity Camera, a feature that allows you to use your iPhone's camera as a webcam for your Mac, can interfere with MagSafe charging on your iPhone. When Continuity Camera is active, your iPhone may not be charging even though it appears to be connected to a MagSafe charger.

2. This issue is caused by the way Continuity Camera uses the iPhone's Lightning port, which can prevent the MagSafe charger from properly communicating with the iPhone to initiate charging. As a result, your iPhone may appear to be charging, but it's not actually receiving power from the MagSafe charger.

3. To ensure your iPhone is charging properly while using Continuity Camera, the article recommends using a traditional wired Lightning cable or a wireless Qi charger instead of MagSafe. This will allow your iPhone to charge without interference from the Continuity Camera feature.
