OPPO A9s

The Oppo A9s comes as an advanced version of the Oppo A9 that was launched in India in July 2019.

The Oppo A9s features the same display as the Oppo A9 a 6.5-inch IPS LCD unit with Full HD+ resolution. The display has a tiny V-shaped notch at the top of the display that houses the front-facing camera and an earpiece. There is no Corning Gorilla Glass protection over the display.

The Oppo A9s, just like its sibling, features a 16MP + 2MP dual-camera at the rear. The 16MP camera is the primary sensor, and it features an f/1.8 aperture. The 2MP camera is a depth-sensor to aid the primary camera in capturing images with background blur. The rear camera can record Full HD videos at 30 frames per second. At the front, the Oppo A9s has a 16MP selfie camera with f/2.0 aperture; it comes with HDR feature as well.

While the Oppo A9 came with the MediaTek Helio P70 SoC, the A9s comes with Snapdragon 665 chipset. And that is the only significant difference between the A9 and the A9s. The Snapdragon 665 is built on 11nm fabrication process; it has eight Kryo 260 CPU cores, and for graphics, the chipset features Adreno 610 GPU. The Oppo A9s features 4GB of RAM and 128GB of storage, and the device runs on Android 9 Pie operating system with ColorOS 6 UI.

Another aspect which sets the A9s apart from the A9 is the battery capacity. Instead of the 4020mAh battery in A9, the A9s comes with a significantly larger, 5000mAh battery pack. There is also a 20W fast charging feature. The device, however, features the old, microUSB port, instead of the newer and more convenient USB Type-C port. And speaking of the connectivity options, the Oppo A9s features dual-SIM with 4G and VoLTE, dual-band Wi-Fi ac, Bluetooth v5.0, and a 3.5mm audio jack.
