Apple has finally announced the iPhone 15 series, which encompasses four new models. The iPhone 15 and iPhone 15 Plus feature some of the upgrades the company brought to the iPhone 14 Pro series last year, while the iPhone 15 Pro and iPhone 15 Pro Max build on last year’s foundation with more changes. Sustainability was at the heart of every phone in the iPhone 15 lineup, so Apple decided to stop making leather products altogether in pursuit of its environmental goals. That means if you want an official Apple case, you’ll need to grab either Apple’s new FineWoven material or a familiar silicone case.
