iPhone 8 is expected to include wireless charging capabilities.
Apple is widely rumoured to sell a wireless charging pad – like those that ship with the Apple Watch – capable of charging the smartphone whenever it is resting on the circular pad.
The decision to introduce wireless charging capabilities is also believed to be behind the move to swap anodised aluminium for glass in the new designs.
Ahead of the iPhone 8 release date, more evidence of the new feature has appeared online.
New images that purportedly show some of the internal components that will power the charging pad have been shared on Chinese social media site Weibo.
Apple is expected to offer inductive charging using the Qi standard.
