Display Comparison
Both phones feature large, HD+ displays, likely around 6.5 inches. Expect similar viewing experiences – adequate for everyday use but not exceptional. Color accuracy and brightness are likely to be average for this price range. The Realme C21 might have slightly better color reproduction due to potentially better panel technology, but this is difficult to confirm without detailed testing.
Camera Comparison
The Realme C21 generally boasts a more versatile camera setup. While both likely feature a primary sensor around 13MP, the Realme C21 often includes additional lenses (macro, depth) for expanded photographic options. Image processing on the Realme C21 is also likely to be superior, resulting in better dynamic range and detail. The ZTE Blade A31 Lite's camera is adequate for basic snapshots but won't impress.
Performance
This is where the Realme C21 shines. The Mediatek Helio G35 chipset, built on a 12nm process, is considerably more powerful than the Unisoc SC9832E (28nm) in the ZTE Blade A31 Lite. The octa-core CPU in the Realme C21 offers significantly higher clock speeds, resulting in smoother multitasking, faster app loading, and a more responsive user interface. The ZTE Blade A31 Lite will likely struggle with demanding apps and games.
Battery Life
Both phones offer large batteries, likely around 5000mAh. However, the Realme C21's more efficient chipset and 10W wired charging (with reverse wired charging) give it an edge. Reverse wired charging allows the Realme C21 to act as a power bank for other devices, a useful feature missing on the ZTE Blade A31 Lite.
Buying Guide
The ZTE Blade A31 Lite is ideal for users prioritizing a very basic smartphone experience with essential features and a tight budget. The Realme C21 is a better choice for those seeking improved performance, a more capable camera, and longer battery life, even if it means spending a little more.
