The Infinix S4 is a smartphone option that offers an appealing combination of design, performance, and camera features in the mid-range class. It features a 6.2-inch IPS LCD display with a resolution of 720 x 1520 pixels and a 19:9 aspect ratio, providing a fairly wide and comfortable viewing experience for everyday content with a pixel density of approximately 271 ppi. The design is also quite lightweight, weighing only 154 grams with a thickness of 7.9 mm, equipped with a glass front and a plastic back and frame that give a solid feel when held.
On the performance side, the Infinix S4 uses a Mediatek Helio P22 chipset built with 12 nm technology, combined with options of 3GB or 6GB RAM and internal storage of 32GB or 64GB. This configuration is adequate for daily use such as browsing, social media, and light applications. The Android 9 Pie operating system also offers a familiar and fairly responsive experience on this device.
The main advantage of the Infinix S4 lies in its camera sector. The single front camera has a 32 MP resolution with an f/2.0 aperture, suitable for those who enjoy selfies with good detail in adequate lighting conditions. Meanwhile, the rear camera features a triple camera setup: a 13 MP main camera with PDAF, an 8 MP ultra-wide angle camera, and a 2 MP depth sensor that helps produce photos with bokeh effects. This combination provides flexibility for various photography needs.
The 4000 mAh battery capacity is another added value of the Infinix S4, supporting all-day activities without frequent recharging. Although it uses a microUSB 2.0 port, charging remains stable and supports OTG for data transfer or additional device use. Complete connectivity with 4G LTE networks, dual-band Wi-Fi, and Bluetooth 5.0 also supports communication and digital entertainment needs.
Suitable for: users looking for a smartphone with a large screen, high selfie camera resolution, and long-lasting battery for daily use such as social media, photography, and communication without requiring very high performance.
