Research has indicated that mobile owners typically replace their devices within two years of ownership, but stragglers do exist, and comScore reported that those who owned iPhone models older than the iPhone 4 were the most interested in an upgrade (46%). iPhone 4 users were the second most likely to plan on upgrading, followed by 4s owners—the model with the largest number of users (nearly 20 million).
Interestingly, 24% of those who owned the iPhone 5s, the most recent version, still planned to upgrade their devices, a group comScore described as “tech-forward consumers,” typically made up of 25-to-34-year-old males. Among female iPhone 5s owners, those ages 13 to 17 were most likely to plan on upgrading, and owners from somewhat upper-income households ($75,000 to $100,000) and coastal regions were also more likely to intend to trade up.
