Oscal C80

  • Potentially lower price point
  • Reliable Unisoc T606 chipset for basic tasks
  • 18W fast charging

  • Slower CPU performance compared to Realme C53
  • Likely less refined software experience

Realme C53 (India)

  • Faster Unisoc Tiger T612 chipset
  • Improved multitasking and app loading speeds
  • 18W fast charging

  • May be slightly more expensive than Oscal C80
  • Software experience may include pre-installed bloatware

Display Comparison

Neither Oscal nor Realme provide display specifications beyond the basic panel type. Given the price bracket, both likely utilize IPS LCD panels. The absence of details like peak brightness, color gamut coverage, or refresh rate suggests a focus on cost reduction. Bezels are expected to be relatively thick on both devices. Without further data, it's impossible to declare a clear winner; display quality will likely be similar and adequate for basic consumption.

Camera Comparison

Detailed camera specifications are unavailable for either device. However, given the target market, it’s safe to assume both will feature a primary camera alongside auxiliary lenses (likely a depth or macro sensor). The image processing capabilities will likely be similar, relying heavily on software algorithms to enhance image quality. Without knowing sensor sizes or lens apertures, a meaningful comparison is impossible. The presence of a 2MP macro camera on either device should be viewed with skepticism; its utility is limited due to the low resolution and lack of optical image stabilization.

Performance

The core difference lies in the chipsets. The Realme C53 utilizes the Unisoc Tiger T612, featuring two Cortex-A75 cores clocked at 1.8 GHz, paired with six Cortex-A55 cores also at 1.8 GHz. The Oscal C80, conversely, employs the Unisoc T606, with two Cortex-A75 cores clocked lower at 1.6 GHz, and six Cortex-A55 cores at the same 1.6 GHz. This 200 MHz clock speed difference on the A75 cores translates to a tangible performance boost for the Realme C53 in CPU-intensive tasks. While both are 12nm chips, the T612’s slightly more aggressive clock speeds will result in faster app launches and smoother multitasking. Both devices likely feature similar RAM configurations, further emphasizing the chipset as the primary differentiator.

Battery Life

Both the Oscal C80 and Realme C53 support 18W wired charging. While the battery capacity isn't specified, typical capacities for phones in this price range are around 5000mAh. The 18W charging, while not particularly fast, should provide a reasonable 0-100% charge time of approximately 2.5-3 hours. The actual battery life will depend heavily on usage patterns, but both devices should comfortably last a full day with moderate use. The similar charging wattage and likely comparable battery capacities mean neither phone has a significant advantage in this area.

Buying Guide

Buy the Oscal C80 if you prioritize a potentially lower price point and are primarily focused on basic smartphone functions like calling, texting, and light social media use. Buy the Realme C53 (India) if you value a smoother user experience, slightly faster app loading times, and a bit more headroom for multitasking and casual gaming, even if it means spending a little more.

Frequently Asked Questions
