Display Comparison
Both phones feature a 6.51-inch display, likely with an HD+ resolution. While the iQOO U3x might have slightly better color accuracy due to its panel type (likely an AMOLED), the Y31s's display is perfectly adequate for everyday use. Expect similar viewing experiences in terms of brightness and sharpness.
Camera Comparison
The vivo Y31s likely boasts a more versatile camera system, potentially including a higher resolution main sensor and improved image processing. While both phones likely feature a similar front-facing camera for selfies, the Y31s's overall camera performance is expected to be superior, especially in low-light conditions. Expect better dynamic range and detail.
Performance
Here's where the Y31s shines. The Snapdragon 480 5G, built on an 8nm process, is significantly more efficient than the iQOO U3x's Helio G80 (12nm). This translates to better overall performance, smoother multitasking, and potentially longer battery life. The iQOO U3x's Helio G80 is still capable for gaming, but the Y31s will handle more demanding titles with ease.
Battery Life
Both phones offer a 5000mAh battery, suggesting similar battery life under moderate usage. However, the Y31s's more efficient chipset could give it a slight edge in real-world battery performance. Both support 18W wired charging, which is relatively slow by today's standards.
Buying Guide
The vivo iQOO U3x Standard is ideal for users prioritizing a large display and solid gaming performance on a tight budget, and who don't need 5G. The vivo Y31s is a better choice for those wanting 5G connectivity, a more modern chipset, and a slightly more refined overall experience, even if it means a small increase in cost.
