iPhone 16 vs Samsung Galaxy S25: Which Should You Buy in 2026?

The Two Flagship Standards

For most smartphone buyers, the decision eventually narrows to two phones: the iPhone 16 or the Samsung Galaxy S25. Both cost $799-999, both offer class-leading cameras, and both define the flagship experience on their respective platforms. The choice is rarely about which phone is objectively better — it is about which ecosystem, software philosophy, and feature set fits your life.

This comparison covers the concrete, measurable differences that should inform your decision.

Performance

iPhone 16: Apple A18 chip, 6-core CPU, 6-core GPU, 8GB RAM. Geekbench 6 single-core: ~3,500. Multi-core: ~8,800. The A18 leads every Android chip in single-core performance, which governs app launch speed and everyday responsiveness.

Samsung Galaxy S25: Snapdragon 8 Elite, 8-core CPU (2x Oryon Prime + 6x Oryon Performance), 12GB RAM. Geekbench 6 single-core: ~3,100. Multi-core: ~9,400. The Snapdragon 8 Elite closes the gap significantly compared to previous Qualcomm generations and leads in multi-core and GPU workloads.
