Infinix has been selling budget smartphones in India for a while now, and has mainly focused on the sub-Rs. 10,000 segment. Many of of the Infinix models we have tested in the past — including the Note 5 (Review), Hot S3X (Review), and Note 5 Stylus (Review) — have fared well in our review process. The Infinix S4 is the company's newest offering, and boasts of a rear triple camera setup and a big battery. Is it better than its competitors? We review it to find out.
Infinix S4 Summary
The Infinix S4 has a plastic body and comes with a flashy paint job. Infinix offers this smartphone in three colour variants, Nebula Blue, Space Gray, and Twilight Purple. The Infinix S4 has a big display measuring 6.21-inches and sports HD+ resolution. The bezels aren’t too big on the sides but the bottom one is bigger. It also has a 19.5:9 aspect ratio for the display.
Infinix has picked the MediaTek Helio P22 SoC to power this smartphone. This chip is paired with 3GB of RAM and 32GB of storage. The smartphone runs XOS 5.0 on top of Android 9 Pie. The UI does not look like stock Android and has comes with preinstalled apps that generate spammy notifications.
The processor isn’t the most powerful but can handle casual gaming. Battery life is good and the 4,000mAh battery is capable of lasting for over a day of regular use. At the back, the S4 has a triple camera setup and a 32-megapixel selfie camera. Photos taken in daylight were good as it had adequate details. Portrait shots were decent but the edge detection wasn’t great. Low-light camera performance was poor.
