- CPU clock speeds are slightly lower than the P4
Display Comparison
The Samsung Galaxy A55 boasts a significant advantage in display brightness, reaching a measured 1010 nits. While the Realme P4’s display specs are currently unavailable, this peak brightness difference translates to superior visibility outdoors. Both devices utilize a 4nm chipset, suggesting similar power efficiency for the display panel itself, but the A55’s higher brightness will inevitably draw more power. We anticipate the A55 will also benefit from Samsung’s well-regarded color calibration and viewing angles, features not explicitly detailed for the P4.
Camera Comparison
Without detailed camera specifications for the Realme P4, a direct comparison is limited. However, Samsung typically prioritizes image processing and consistency across its A-series devices. The A55 likely benefits from Samsung’s advanced computational photography algorithms. The absence of information regarding sensor size and OIS on the P4 makes it difficult to assess its low-light performance or video stabilization capabilities. We can assume the A55 will offer a more refined and reliable camera experience, especially in challenging conditions. The inclusion of a 2MP macro camera on either device is largely a marketing feature with limited practical utility.
Performance
Both the Realme P4 and Samsung Galaxy A55 employ octa-core CPUs with a similar core configuration – four Cortex-A78 performance cores and four Cortex-A55 efficiency cores. However, the Galaxy A55 edges ahead with slightly higher clock speeds on its A78 cores (2.75 GHz vs 2.6 GHz on the P4). Both are built on a 4nm process, indicating comparable efficiency. The Dimensity 7400 in the P4 is a newer chip, potentially offering architectural improvements in AI processing and image signal processing, but the A55’s higher CPU clock speeds may translate to a slight edge in CPU-bound tasks. The GPU performance is unknown for both, but the Dimensity 7400 is generally considered a stronger performer in graphics.
Battery Life
The Samsung Galaxy A55 demonstrably leads in battery endurance, achieving 13 hours and 27 minutes of active use. The Realme P4’s battery capacity is unknown, but its 80W wired charging is a standout feature. This allows for incredibly fast top-ups – significantly faster than the A55’s 25W charging. While the A55’s larger battery provides longer runtimes, the P4’s charging speed mitigates downtime. The P4 also includes 10W reverse wired charging, a feature absent on the A55, allowing it to charge accessories or other devices.
Buying Guide
Buy the Realme P4 if you need blazing-fast charging and prioritize peak CPU performance for demanding tasks. This phone is ideal for users who frequently find themselves needing to quickly replenish battery levels and enjoy mobile gaming. Buy the Samsung Galaxy A55 if you prefer a more balanced experience with exceptional battery endurance, a brighter and more visible display in sunlight, and Samsung’s established software ecosystem. This is the better choice for everyday users and media consumers.
Frequently Asked Questions
❓ Does the Exynos 1480 in the Galaxy A55 tend to overheat during prolonged gaming sessions?
The Exynos 1480 is a 4nm chip, indicating good thermal efficiency. While it may warm up during extended gaming, it's unlikely to experience significant throttling due to its efficient design and Samsung's thermal management solutions. The larger chassis of the A55 also aids in heat dissipation.
❓ How long does it realistically take to fully charge the Realme P4 from 0% to 100% with the 80W charger?
With 80W SuperVOOC charging, the Realme P4 is expected to charge from 0% to 100% in approximately 30-40 minutes, depending on battery capacity. This is a substantial advantage over the Galaxy A55's 25W charging, which will take considerably longer.
❓ Is the difference in CPU clock speed (2.75 GHz vs 2.6 GHz) between the A55 and P4 noticeable in everyday tasks?
The difference in CPU clock speed is relatively small and unlikely to be noticeable in most everyday tasks like browsing, social media, and messaging. However, it may result in a slight performance advantage for the A55 in CPU-intensive applications like video editing or demanding multitasking.
❓ What kind of gaming performance can I expect from the Realme P4 with the Dimensity 7400?
The Dimensity 7400 is a capable chipset for mid-range gaming. It should handle most popular titles at medium to high settings with smooth frame rates. While specific frame rate numbers depend on the game and settings, the P4 is well-equipped for a solid gaming experience.
