It can be assumed that consumers that already purchased the iPhone 8 and iPhone 8 Plus would not be upgrading to the iPhone X. However, there are some unexpected buyers that have decided to trade-in their newly purchased smartphones to get a chance in becoming the proud owners of the bezel-less iPhone.

According to Yahoo Finance, electronics recycling site Decluttr.com reports that it has received more trade-ins of the iPhone 8 and iPhone 8 Plus than any previous iPhone model. It has been reported that potential iPhone X customers were enticed by the exclusive features that came with the iPhone X, even though it features the same A11 Bionic SoC as the remaining two models.
