- Software experience may not be as polished as Samsung’s One UI.
Samsung Galaxy A55
- Slightly longer battery life in active use.
- Samsung’s One UI offers a refined and feature-rich software experience.
- Strong brand reputation and established ecosystem.
- Significantly slower 25W charging.
- Less powerful Exynos 1480 chipset.
- Dimmer display can be challenging in bright sunlight.
Display Comparison
The Oppo Reno12 boasts a significantly brighter display, reaching a measured 1378 nits compared to the Galaxy A55’s 1010 nits. This translates to superior visibility outdoors under direct sunlight. While both utilize 4nm chipsets, the Reno12’s brighter panel will draw slightly more power. We lack data on panel technology (LTPO vs standard OLED) but the brightness difference is a key differentiator for users who consume a lot of media outdoors. Bezels appear comparable based on available imagery, and color accuracy is likely similar given both brands’ focus on vibrant displays.
Camera Comparison
Without detailed camera specs, a direct comparison is limited. However, the Reno12’s brand positioning suggests a stronger emphasis on camera capabilities. While both likely feature a multi-camera setup, the Reno12 may prioritize larger sensors and more advanced image processing algorithms. The Galaxy A55’s camera is likely competent, but Oppo often focuses on computational photography to enhance image quality. We can safely assume both will include standard wide, ultrawide, and potentially macro lenses, but the Reno12 is likely to offer a more versatile and higher-quality camera experience.
Performance
Both phones employ octa-core CPUs with a similar core configuration (4x Cortex-A78 and 4x Cortex-A55), but the Galaxy A55’s cores are clocked slightly higher at 2.75 GHz versus the Reno12’s 2.5 GHz. However, the Reno12’s Mediatek Dimensity 7300 Energy, built on a 4nm process, is generally considered more efficient and offers a performance advantage in GPU-intensive tasks. The Dimensity’s architecture is optimized for sustained performance, potentially leading to less thermal throttling during extended gaming sessions. RAM speed (LPDDR5x is expected on both) is not specified, but the chipset difference is the primary performance driver.
Battery Life
The Oppo Reno12 achieves an active use battery score of 14:53h, outperforming the Samsung Galaxy A55’s 13:27h. This difference, while not massive, is notable. However, the Reno12’s 80W wired charging is a game-changer, reaching 47% charge in just 18 minutes and 100% in 46 minutes. The Galaxy A55’s 25W charging is significantly slower, making the Reno12 the preferred choice for users who frequently need to top up their battery quickly. The Reno12 also offers reverse wired charging, a feature absent on the A55.
Buying Guide
Buy the Oppo Reno12 if you need a phone that can handle demanding tasks like gaming and video editing with ease, and if minimizing charging time is a priority. Buy the Samsung Galaxy A55 if you prefer a more refined software experience, a slightly longer-lasting battery for everyday use, and value Samsung’s ecosystem of features and services.
