Why the 256GB Model Holds Strong Resale Power

With more space for apps, 8K video, and high-resolution content, the 256GB model is highly desirable among second-hand buyers. It offers the same top-tier Snapdragon 8 Gen 2 processor, advanced triple-lens camera, and fast 5G performance — with more room to store what matters.

Because of this, it often attracts higher trade-in prices than its 128GB counterpart.
