It sports a 6.21-inch IPS LCD display with HD+ resolution (720 x 1520 pixels), offering a wide and comfortable viewing experience for watching videos, browsing, or playing light games. The 19:9 screen ratio gives a modern feel with thin bezels and an approximately 80.7% screen-to-body ratio, making the body feel compact despite the relatively large screen.
In terms of performance, the Infinix Smart3 Plus is powered by a Mediatek Helio A22 (12 nm) chipset paired with either 2GB or 3GB of RAM and 32GB of internal storage. This combination is sufficient for running daily applications and light multitasking on Android 9.0 Pie. While not the fastest in its class, this performance is reliable for social media, chatting, and streaming music or videos.
For photography needs, the smartphone is equipped with a triple rear camera setup featuring a main 13 MP f/1.8 sensor with PDAF, plus a 2 MP auxiliary lens to help produce photos with better bokeh or depth effects. The 8 MP front camera is also adequate for selfies and video calls, delivering satisfying results in good lighting conditions.
Regarding battery life, the Infinix Smart3 Plus has a non-removable 3500 mAh battery. This capacity is enough for normal daily use, especially with the HD resolution screen that does not heavily drain power. However, charging is done via a microUSB 2.0 port, which is standard and common for devices in this class, though it does not support fast charging.
Connectivity features include 4G LTE networks, Wi-Fi, Bluetooth 5.0, and GPS. The smartphone also supports dual nano SIM cards, making it easy for users to manage two numbers on one device. Weighing 148 grams and measuring 7.8 mm thick, the phone feels light and comfortable to hold.
