Overview: This report offers a concise comparison of the evolving BoM (Bill of Materials) for Samsung’s Galaxy S23 Ultra, S24 Ultra, and the latest S25 Ultra. It highlights key cost drivers, including rising SoC costs due to ongoing process and architecture upgrades, as well as fluctuations in memory and casing costs driven by supply dynamics and material changes. Meanwhile, reductions in RF and camera component costs have helped offset some of the increases, reflecting the complex balance of innovation, design choices, and market forces shaping the Ultra series’ cost structure.
