The iPhone 8 won't be the only device in Apple's arsenal to feature an all-glass design. According to images acquired by 9to5Mac, via Sonny Dickson, the upcoming iPhone 7s and iPhone 7s Plus will feature glass back designs, allegedly to support wireless charging.

Reports about inductive charging coming to the the next iPhone have persisted for months. Initially, people thought the iPhone 8 would exclusively feature the technology, but these dummy units suggest otherwise. If true, Apple is planning to support wireless charging in all of its new smartphones.

The adoption of inductive charging is a big one for fans who have waited for Apple to support the technology. Some of Apple's biggest competitors, including Samsung, have supported wireless charging methods for years.

It's unclear what other changes will come to the iPhone 7s and iPhone 7s Plus (other than an upgrade in specs). Aesthetically, the dummy unit features a pretty familiar design despite the glass back panel.

With the introduction of an iPhone 7s, iPhone 7s Plus, and iPhone 8, Apple's smartphone lineup will be the strongest it has ever been. The iPhone 7s and iPhone 7s Plus upgrade appear to be iterative updates, as we've seen in the past, but the iPhone 8 is expected to adopt a number of new technologies, including an edge-to-edge display and a "function area."

Although inductive charging is said to play a major role in Apple's revamped iPhone lineup, the feature may not be ready when the devices launch. Apple is expected to hold its next major event in September.
