Infinix has been selling budget smartphones, and the company has focused its attention on the price segment of less than $135. We have reviewed several models of the Infinix brand, including Note 5, Hot S3X, and Note 5 Stylus (Review). Infinix S4 is the latest smartphone of the company, and this smartphone is equipped with three rear cameras. The phone has a large battery for life. Is the Infinix S4 better than its counterweight handset? We have reviewed it to find out this.
Infinix S4 design
At first glance, it is hard to believe that Infinix S4 is priced below $135. The Infinix S4 is well designed and comes with a glossy gradient back panel. The Infinix S4 has three color variants – Nebula Blue, Space Gray, and Twilight Purple. We have received the Nebula Blue Color variant of Infinix S4 for review, and it is very good looking.
Looking at the glossy back panel, it seems that it is made of, glass but plastic has been used to make it. Due to having a glossy rear panel, fingerprints fall easily on it. In the retail box, you will find a case from Infinix. The Infinix S4 has a larger display with waterdrop, notch, and the bezels are not too thick.
The earpiece of the Infinix S4 is quite slim and has got space between the frame and the display. We found that the phone fits comfortably in hand and, it was not too heavy. Infinix has got the power and volume buttons on the right side of the phone.
We found that the volume button is placed slightly upwards, but the button still works well. The SIM tray is located on the left side of the phone. The triple camera setup on the back of the phone will draw your attention. It is not common to find three rear cameras on the back panel of the phone in this price segment, so we were a little surprised to see the triple rear camera setup in the Infinix S4.
For the information of the people, let us know that the camera module is slightly embossed. Just below the camera module is a quad-LED flash. For security, the fingerprint sensor will be found on the back of the phone. The hand reaches the sensor easily. At the bottom of the phone, you will find a loudspeaker grill, 3.5mm headphone jack, and micro-USB port.
Infinix S4 specifications and software
The Infinix S4 has a 6.21-inch HD (720×1520 pixels) display with an aspect ratio of 19.5: 9 and uses 2.5D curved glass for display protection. Its screen-to-body rate is 89 percent.
The phone has an eye-care feature that filters the blue latch to protect the eyes from stress. The Infinix S4 uses the MediaTek Helio P22 octa-core processor. Gradually, the use of this chipset is becoming common in this price segment. The same processor has also been used in Realme C2 and Oppo A1k.
There is only one variant of Infinix S4, which is equipped with 3 GB RAM and 32 GB storage. It has a dedicated microSD card slot with the help of which it is possible to increase the storage up to 256 GB. Connectivity includes Bluetooth version 5, Wi-Fi 802.11 a / b / g / n, GPS and 4G VoLTE. To make life on the phone, a 4,000 mAh battery has been provided, and a 10-watt charger will be available in the retail box.
The dual-sim Infinix S4 runs on XOS 5.0 based on Android Pie. The phone has some UI customization and does not look like the stock Android.
The phone also has theme support, and you can also download other themes through the pre-installed Themes app if you wish. Infinix S4 will also get some apps pre-installed like PHX browser, Google Apps, and Danger Dash.
Infinix S4 Performance
The Infinix S4 uses the MediaTek Helio P22 processor and has excellent performance. The phone did not slow down while scrolling through the menu or switching between applications. There was no problem in multitasking due to the phone having 3 GB of RAM. Infinix S4 takes a little longer than normal to load large apps.
PUBG Mobile had low preset, graphics quality smooth, and frame rate set to medium. During gaming, the phone did slow down a bit. After playing the game for 20 minutes, the battery dropped by 5 percent, and the phone was also slightly warmed on the backside of the phone. We found that the fingerprint sensor and face recognition feature unlock the smartphone faster.
The Infinix S4 has a 4,000 mAh battery to burn. We used WhatsApp, Google Maps for navigation, running benchmarks, and taking some camera samples. In our HD video loop test, the phone supported for 17 hours and 35 minutes. The charger that comes with the phone takes up to 31 percent in 30 minutes and takes about 2 hours to fully charge the phone.
The Infinix S4 has three rear cameras, a 13-megapixel primary sensor with aperture F / 1.8, an 8-megapixel ultra-wide camera with an aperture F / 2.2, and a 2-megapixel depth sensor. Just below the camera module is a quad-LED flash. There is a 32-megapixel selfie camera for selfie and video calling, which has an aperture F / 2.0.
The camera app has an AI feature and will be AI-enabled by default in Infinix S4. Buttons are available for HDR and flash, as well as buttons for switching to wide-angle sensors. Modes like Beauty, Bokeh, Video, and AR Shot will also be available in the camera app.
When taking portrait shots, you can choose the level of a blur, but we found the edge detection quality to be below average. Quality was not very good in low-light. The photos were not sharp, and grains were visible in the pictures. Selfies captured with the front camera came out well. The phone also has a face detection feature that helps in getting the right exposure before taking a picture. And The phone is capable of recording videos of a maximum of 1080p resolution. The phone does not have stabilization support.
The Infinix S4 is equipped with three rear cameras in the price segment of less than $ 135. Its wide-angle sensor comes in handy when shooting in landscape mode and the primary sensor captures good pictures in daylight. But the low-light camera performance of the phone is not very good. The MediaTek Helio P22 processor in this price segment is not a very powerful chipset but still, it works correctly.
