The iPhone business, which accounts for around half of Apple’s overall revenue, is in a sales slump following years of mostly incremental upgrades to its devices.

The next big upgrade to Apple’s mobile devices could be foldability, according to multiple reports published Sunday. According to The Wall Street Journal,

Apple is said to be working on two foldable devices, which will be launched in the coming years. One model, as per The Wall Street Journal, will be a larger device with a 19-inch display that could compete with desktop monitors. The other will be a smaller foldable iPhone with a screen larger than the 6.9-inch iPhone 16 Pro Max.
