Numerous rumors about Apple’s iPhone 13 have circulated the Internet, just like every previous model. A U.S. patent application indicates that Apple could go buttonless with the iPhone 13. It states that Apple is looking into “capacitive sensing input device” and that physical buttons may be replaced by invisible backlit holes that will remain visible when left unaltered. The input device’s metal frame can be bent to cause a change of capacitance, which is used to control an electrical device’s function. Apple claims that the input device is invisible because it is made from the same material as its housing. The input device may be selectively visible to the user or hidden by backlit holes. Nothing has been confirmed, so keep checking back for more information about the iPhone 13 as well as its new features and upgrades. Here’s what to expect at the tech giant’s fall event, in case you haven’t seen it.
