Will wireless charging work through a phone case?

Yes, through cases up to 3mm thick. MagSafe cases work best with magnetic mounts. Thick wallet cases or metal cases will block charging. Remove pop sockets before mounting.

Does wireless car charging damage phone batteries?

No — modern phones manage charging heat and speed. The ESR CryoBoost actively cools to prevent heat-related degradation. Wireless charging is slightly less efficient than wired but does not damage the battery.
