Low- and Mid-Tier Mobile for the Real World (2025) – CSS Wizardry

Web performance testing requires real mobile devices to accurately assess user experience. For 2025, the Samsung Galaxy A15 5G represents an ideal low-tier testing device at $199, while the Galaxy A54 5G serves as the mid-tier benchmark at $450. Both devices offer global availability, multi-year software support, and hardware characteristics that align with Chrome DevTools' throttling presets. The research emphasizes that low-tier doesn't mean old devices, but rather current budget-conscious mainstream options that billions of users actually own, making them essential for realistic performance testing.
