According to a recent post on Appleinsider, Apple could return to it’s popular 4-inch metal iPhone form factor next year (2016), with the aim to mass produce affordable iPhone 5s upgrades, boasting a powerful A9 system-on-chip, metal casing and next-generation software.
According to information gathered by AppleInsider – it looks like Apple might market the 4-inch iPhone as a “budget” model, meaning the target demographic does not include customers looking for the latest technology in a smaller form factor. The company’s last attempt at the low end was the plastic-backed iPhone 5c.
