Performance: Powered by Qualcomm Snapdragon 6s 4G Gen 1
Under the hood, the OPPO A5i packs a capable Qualcomm Snapdragon 6s 4G Gen 1 chipset, built on an 11 nm fabrication process, ensuring efficient power consumption and smooth multitasking. The octa-core CPU is split into:

On the front, the phone houses a 5 MP fixed-focus camera with an aperture of f/2.2 and wide-angle lens, perfect for selfies and video calls. It also supports Full HD video recording at the same 30 fps rate.

Moreover, it supports 45W Super VOOC fast charging, allowing you to quickly top up the battery and minimize downtime — a feature rarely seen in budget smartphones.

It also comes with essential sensors including a side-mounted fingerprint sensor for quick and secure unlocking, along with light, proximity, and accelerometer sensors.
