Ideally, you are not supposed to use the iPhone case if you use the wireless charger occasionally. You have three options here to avoid this situation.
- Use the thin or no iPhone case while using the wireless charger for iPhone.

In addition to that, the wired charging is the direct contact charging to the iPhone. So the energy loss is minimum compared to the wireless charging technology. You can get Apple’s iPhone Lightning Cable or thrid-party lightning cables to change your iPhone.
