Apple discontinued the 256GB Apple iPhone 7 in a bid to spur iPhone 8 sales
Apple did this to spur sales of the Apple iPhone 8 and Apple iPhone 8 Plus, both of which have a 256GB model. The upcoming Apple iPhone X also will feature a model with 256GB of native storage inside. Currently, sales of the iPhone 8 are said to be lagging behind sales of previously "just-launched" new iPhone models. Some are putting the blame for weak iPhone 8 sales on the premium iPhone X as many want to wait and check out the tenth anniversary model before making their purchasing decision.
Interestingly, consumers have started to Google "iPhone 7" more than "iPhone 8." And last Monday, we told you that a survey conducted by KeyBanc Capital Markets revealed that the 2016 iPhone 7 is outselling the 2017 iPhone 8 models. The iPhone 8 features the more powerful A11 Bionic chipset, and the iPhone 8 Plus includes the Portrait Lighting feature that allows users to snap selfies with more dramatic backgrounds. In addition, the 2017 models support wireless charging.
