These smartphone trade-in stats will probably make Galaxy S9 owners cry
June 03, 2025
Many of us buy smartphones knowing that, within a year or two,we will resell that phoneon the used market. Even if we decide not to sell it ourselves, we’ll likely trade it in when we buy an upgraded model.
BankMyCelljust published a slew of new data pertaining to the smartphone trade-in market, including both Android and iOS devices. As one would expect, the data proves that smartphones lose a lot of their trade-in value a year after they launch. However, you might be surprised by just how much.

In the cases of last year’s major flagships, theSamsung Galaxy S9 and Galaxy S9 Plus, the phones’ overall values dropped by nearly 60 percent in just one year’s time. In other words, a buyer would have paid $720 for a new Galaxy S9 in March of 2018 but now that device would only earn them an average of $290 on a trade-in.
What’s more, smartphone trade-in values drop as soon as you “drive it off the lot,” so to speak. Within the first month of opening your brand new Galaxy smartphone, it loses about 42 percent of its original retail value when it comes to trades.

This is comparatively worse than the trade-in values for iPhones. The iPhone X, for example, launched at a retail price of $999, but by the time theiPhone XSrolled around its value dropped to $690, or by nearly 31 percent. That’s about half as much of a drop as the Galaxy S9 experienced over a similar length of time.
BankMyCell builds its data off various trade-in values offered by different companies and then delivers an average. It’s important to note this because some companies will offer exceptional trade-in deals that will up the value of any given phone substantially. For example,Samsung is giving $550 worth of trade-in creditsfor the Samsung Galaxy S9 right now if you put it towards aSamsung Galaxy S10. That’s twice as high as what BankMyCell claims here, and also over $100 more than what most sellers are asking for the device onSwappa.

In other words, it pays to shop around when it comes to smartphone trade-in values.
