After months of rumours and speculation, Apple has finally unveiled the latest four-inch version of its iPhone range.
Dubbed the iPhone SE – rather than the iPhone 5se, as was suggested ahead of the official announcement – the device is a revamped version of the iPhone 5s.
It brings the specs of its four-inch handset up to date to match those of the iPhone 6, while catering to those who want a smaller device.
Although four-inch smartphones were something of an industry standard in the early 2010s, the current vogue is for much larger models.
The industry giant's flagship device remains the iPhone 6s, which carried over the 4.7-inch screen size introduced by its predecessor, the iPhone 6. Even this size still remains is among the smallest available on the market today.
Several major improvements over the iPhone 5s are offered by the iPhone SE, with processing power doubled and graphics performance increased four-fold.
Battery life is longer and Apple could be hoping the new device will help persuade those still using an iPhone 5, iPhone 5s or iPhone 5c to upgrade – particularly if they have so far been put off by the larger size of the iPhone 6s or the 5.5-inch iPhone 6s Plus.
Chief executive officer of Apple Tim Cook said more than half of those using smaller iPhones have not upgraded to an iPhone 6 or newer, which represents a large untapped potential market.
Philip Schiller, Apple's senior vice-president of worldwide marketing, said: "iPhone SE is an exciting new idea – we started with a beloved, iconic design and reinvented it from the inside out. The result is the most beautiful and powerful phone with a four-inch display in the world."
"[The] iPhone SE is packed with a stunning four-inch Retina display [and] longer battery life," he commented, adding: "Everyone who wants a smaller phone is going to love iPhone SE."
