Camera Comparison
The Oppo A57 4G and A57s generally feature a 50MP main camera, a 2MP depth sensor, and a 16MP front camera. Image quality is expected to be comparable, with decent performance in well-lit conditions. Low-light photography will likely reveal noise and a lack of detail. Software processing plays a significant role in the final image quality, and Oppo's optimizations might differ slightly between the models.
Performance
Performance is virtually identical. Both devices are powered by the Mediatek Helio G35 chipset and an octa-core CPU. Don't expect blazing-fast speeds; these phones are designed for basic tasks like browsing, social media, and light gaming. Demanding games will require lower settings.
Battery Life
The battery capacity is likely the same (5000mAh) for both devices. However, the A57s shines with its faster 33W charging, completing a full charge in approximately 69 minutes, while the A57 4G takes longer (estimated around 90-100 minutes).
Buying Guide
The Oppo A57 4G is ideal for budget-conscious users who prioritize affordability and don't heavily rely on fast charging. The Oppo A57s is a better choice for those who value quicker charging times and are willing to spend a bit more for the convenience.
