Apple to Reportedly Stop Production of iPhone 5c in 2015
Originally released as a lower-cost option last year, the iPhone 5c is currently available in a single 8GB configuration alongside the iPhone 5s, iPhone 6, and iPhone 6 Plus. It is likely that Apple will stop production of the iPhone 5c to streamline its iPhone lineup, as every handset would then likely be equipped with a Touch ID fingerprint sensor.
Apple's iPhone 5c saw lower-than-expected sales after its debut in 2013 due to high demand for the then-flagship iPhone 5s. Apple did attempt a renewed push late last year to promote the iPhone 5c, debuting ads for the device on popular blogging platform Tumblr and on websites like Yahoo.com. Other reports also suggested that Apple cut iPhone 5c production significantly while ramping up iPhone 5s production to meet customer demand last year.
