Summary
- The Realme C21Y and vivo Y20i both feature a 6.5-inch IPS LCD display with a resolution of 720 x 1600 pixels and a 60Hz refresh rate.
- In terms of performance, the C21Y is powered by the Unisoc T610 chipset, while the Y20i utilizes the Qualcomm Snapdragon 460, with the latter offering slightly better efficiency due to its 11 nm process.
- Both phones have a triple rear camera setup with a 13 MP main sensor, but the Y20i has a wider aperture at f/1.8 compared to the C21Y's f/2.2, potentially enhancing low-light performance.
- Battery capacity is identical at 5000 mAh, but the Y20i supports 18W fast charging, whereas the C21Y does not support fast charging.
- Both devices run on Android 10, but the Y20i features Funtouch 10.5, which may offer a different software experience compared to the C21Y's Android 10/11.
- Build quality is similar, with both having a plastic frame and back, though the Y20i is slightly lighter at 192.3g compared to the C21Y's 200g.
