Methodology

Smartphones are compared on AnTuTu v10 benchmark scores, chipset, display size and refresh rate, battery capacity, rear and front camera resolution, RAM and storage across launch variants, weight, and launch pricing (USD). Each model shows its base variant with the top-spec configuration noted where multiple variants exist. Benchmark scores reflect the listed chipset variant; real-world battery life and camera quality depend on software tuning, not just hardware numbers.
