Price Drops by Operating System (4-Years)

BankMyCell tracked hourly trade-in market quotes from multiple buyback vendors across 500 devices, including storage capacity options. The chart below shows the average yearly depreciation of iOS and Android smartphones, grouped via release price.

The tracked flagship Android VS iOS devices were priced at $699 and over at launch, and budget Androids are grouped at $399 and below.

As the chart shows, consumers with an iOS device can expect a comfortable trade-in return in the first 12-36 months of release – with iPhones only losing -33.95% of their original buyback value by the end of year three. By comparison, flagship Android devices lost an average of -67.87% in the same period, with year-on-year depreciation consistently averaging double the amount of an iPhone.

Consumers buying a budget Android device for $350 would most likely be worth less than $43 after 4 years.
