According to Dipli, a French company enabling trade-in programs, resale pricing strategies must evolve beyond simple depreciation models. Using nine years of market data and over 520,000 daily pricing points, Dipli reveals that the Apple iPhone continues to lead the market in value retention. After 12 months, Apple iPhone models retain 57.1% of their original value. That number still stands at 41.8% after two years and 25.4% after four years, based on aggregated data for the Apple iPhone 11 to 14.
Competitors fall behind in value
In contrast, Samsung smartphones show significantly steeper depreciation. Devices drop to 39% of their value at 12 months and just 14.1% after four years. Google models hold 40.9% at one year and drop further to 12.6% at 48 months. Dipli’s analysis highlights the size of the gap, not just in value but in strategic potential for retailers and operators offering trade-in services.
Data insights fuel new solutions
The company’s new solution, DipliForward, responds to this pricing gap with a data-backed, forward trade-in offer. It enables telcos to lock in future buy-back prices based on real-time market signals. The service also provides IMEI-level transparency, full insurance coverage through Aon, and aims to help businesses build stronger, more predictable resale offers.
Why value retention matters
Dipli argues that predictable value translates to more loyal customers, lower operational risks, and a measurable competitive edge. For a growing number of European telcos and retailers, integrating such predictive pricing tools could mean a more sustainable and profitable secondary smartphone market.
