Editorial report
Realme C21 4 GB / 64 GB / Global technical sheet
The Realme C21 suits people looking for a basic phone for everyday tasks who value a high-capacity battery. Its main trade-offs are the display, camera and charging speed; battery capacity, by contrast, is higher than that of most phones of its time.
The 6.5″ IPS LCD display gives the phone a broad viewing area, but its 400-nit brightness is among the weakest of its time. Its 270 ppi density and 60 Hz refresh rate also fall short of most phones launched around the same time. The 13 MP camera uses a 1/3.06″ sensor, among the smallest of its time, and lacks optical image stabilization. Video recording reaches 1080p at 30 fps.
The 5000 mAh battery has more capacity than that of most phones of its time, while 10 W charging is slower than on most of them. Reverse charging is also supported. This version pairs 3 GB of RAM with 32 GB of storage; the Realme C21 is also sold in a 4 GB / 64 GB configuration, and storage is expandable. It supports Dual Nano-SIM and runs Android 10.
Its overall NeoScore is 4.0. The Realme C21 is best suited to people who prioritize battery capacity and basic functions, and can accept a modest display, a camera without optical image stabilization and slow charging.
