Display Comparison

Both the Realme C21Y and C25Y typically feature a 6.5-inch IPS LCD display with a resolution of 1600 x 720 pixels (HD+). While the panels are similar in size and resolution, slight variations in color accuracy and brightness may exist depending on the specific production batch. Expect decent viewing angles and adequate clarity for everyday use.

Camera Comparison

The Realme C21Y generally features a 13MP main camera, a 2MP macro lens, and a 2MP depth sensor. The C25Y often includes a 48MP main camera, a 2MP macro lens, and a 2MP depth sensor. The C25Y's higher resolution main camera *should* offer slightly better image quality, especially in well-lit conditions, though software processing plays a significant role. Both offer basic video recording capabilities.

Buying Guide

The Realme C21Y is a good option for users on a very tight budget who prioritize basic functionality and don't mind slower charging. The Realme C25Y is ideal for those who want a slightly better overall experience, particularly faster charging, without breaking the bank.
