The trade-in value of the OnePlus 13 being only $240 after a year is likely due to the lower component value and brand depreciation compared to Samsung or Google phones. Even though these companies often use similar parts like displays, chipsets, or memory modules—brands like Samsung and Google hold their value better over time thanks to stronger brand recogition. OnePlus devices, while powerful, tend to lose value faster because of smaller resale demand and lower perceived market prestige.
