Pros & Cons


  • Can handle some gaming


  • No Gorilla Glass protection


Oppo is a part of the same family as Realme, Vivo and OnePlus. It is one of the known brands that produce lots of affordable options and is also the pioneer of the beauty filter that is ubiquitous today. The A15s from Oppo is another affordable choice that has ample power and performance for most average users.

Oppo A15s internals and OS

The main chipset at the heart of the Oppo A15s is the Mediatek MT6765 Helio P35, which was produced using the 12nm method and has a CPU speed of 2.3GHz. This is closer to an entry-level processor and is integrated with the PowerVR GE8320 graphics processor. These two combined with 4GB of RAM can handle some affordable gaming as well. This is also due to the PowerVR GE8320 being optimised for some gaming performance.

The storage space is at 64GB and one can add on another 256GB via a microSD card that fits into a dedicated slot.

The base layer for the OS is Android 10, this OS has Machine Learning and can pick up on a users' patterns, reflecting a more appropriate functional flow in response. This lets your device be optimised for you, leading to a lot more efficient performance. On top of this, Oppo has layered the ColorOS 7.2 as the User Interface. With ColorOS 7.2 users have some more performance tweaks such as Anti-Fragmentation which is a proprietary system. This keeps fragmentation of the physical and virtual memory to a minimum, improving the overall performance

The ColorOS 7.2 also features Super Power Saving Mode with great battery management to take advantage of. There is also the Oppo Lab; this is a feature via which users can up-vote or down-vote additions to the ColorOS. It is managed by a team at Oppo and they can optimise the future versions of ColorOS based on this information.

Camera and Display

With a triple camera setup for the main module, the Oppo A15s has ample modes as well to amp up your photography. The main sensor is a 13MP on and has an aperture of f/2.2 which shoots somewhat wide. The remaining two sensors are both 2MP and both have an aperture of f/2.4. One of these works for shooting macro and the other is a depth sensor which helps add more layers to your images. The app allows for portrait mode, HDR and AI scene enhancement.

On the front, there is a selfie camera that has an 8MP sensor with an aperture of f/2.0. It shoots wider shots, helping make room for group selfies. Both sides can shoot video at 1080p with a frame rate that is 30fps.

All the photography is viewed on the 6.52-inch display. This is a generally large display and has a resolution of 720 x 1600pixels, bringing pixel density to 269ppi. An HD display based on an IPS LCD panel makes for crisp and clear visuals for your games and streaming. There is the downside of not having Gorilla Glass for protection.

Sensors, connectivity and battery

There are only two feedback sensors, one is the accelerometer and the other is the proximity sensor. A fingerprint reader has also been incorporated and is set into the back for quick access.

For connectivity, Oppo has given the A15s WiFi, Bluetooth, GPS, Dual SIM and Data. Porting options include a microUSB and a 3.5mm audio jack as well.

The battery in the Oppo A15s is a Li-Polymer one, it has a capacity of 4230mAh which is more than ample for this spec range and would easily see on through a day of regular usage. 


With a mid-range price, the Oppo A15s has ample power for most average users who may dabble in some gaming. There is the option for a black or a white body with this smartphone.
