Editorial report
Infinix Smart 20 4 GB / 128 GB / International technical sheet
The Infinix Smart 20 suits buyers who want a large screen and smoother scrolling without making photography or performance a priority. Its main trade-off is clear: the 8 MP rear camera and hardware are among the weakest of their time.
The display is a 6.78″ IPS LCD running at 120 Hz, a typical refresh rate for its time. The body brings two concrete advantages: it weighs 188 g and is 7.7 mm thick, making it lighter and thinner than most phones of its time. However, its 259 ppi density and 700-nit brightness are worse than most, so the large panel does not deliver especially sharp or bright images.
This version has 4 GB of RAM and 64 GB of eMMC 5.1 storage, with expandable storage available. The phone is also sold in a 4 GB / 128 GB configuration. Its 5,200 mAh battery supports 15 W charging and reverse charging. Connectivity includes Dual Nano-SIM, NFC, USB Type-C, Bluetooth 5.2, Wi-Fi 5, and GPS, A-GPS, GLONASS, BeiDou and Galileo.
The rear camera uses 8 MP and a 1/4″ sensor, with no optical stabilization or optical zoom. With an overall NeoScore of 4.2, the Infinix Smart 20 is among the weakest phones of its time. It remains a basic choice for a large screen and light everyday tasks, but not for demanding photography or heavier workloads.
