wireless charging iPhone 7 with Qi receiver
How can I tell if my iPhone 7 with Qi receiver is charging on wireless charging pad?
iPhone 7, iOS 15
The iPhone 7 does not support wireless charging.
If it did, the battery icon would turn green, with a lightning bolt through it, like it does when it charges through a cable.
Wireless charging was only added to the iPhone 8 and later.
