Display Comparison
The Samsung Galaxy M51 boasts a significantly brighter display, reaching a measured 677 nits, compared to the Coolpad Cool 6’s unspecified brightness. This makes the M51 far more usable outdoors under direct sunlight. While both devices lack high refresh rates, the M51’s higher peak brightness and infinite contrast ratio contribute to a more vibrant and immersive viewing experience. The Cool 6’s display specifications are less detailed, suggesting a lower-quality panel overall.
Camera Comparison
Both phones feature photo/video capabilities, but detailed camera specs are limited. Without sensor size or aperture information, a direct comparison is difficult. However, Samsung generally employs more sophisticated image processing algorithms, suggesting the M51 will likely produce more refined images. The Cool 6’s camera system is likely geared towards basic photography, while the M51 may offer more features and better low-light performance. The presence of a 2MP macro lens on either device is unlikely to significantly impact image quality.
Performance
The core difference lies in the chipsets. The Samsung Galaxy M51’s Qualcomm Snapdragon 730G (8nm) is a substantial upgrade over the Coolpad Cool 6’s MediaTek Helio P70 (12nm). The 8nm process node of the Snapdragon 730G translates to better power efficiency and reduced thermal throttling during sustained workloads. The Snapdragon 730G’s CPU configuration – 2x2.2 GHz Kryo 470 Gold & 6x1.8 GHz Kryo 470 Silver – offers a noticeable performance advantage over the Cool 6’s 4x2.1 GHz Cortex-A73 & 4x2.0 GHz Cortex-A53 setup, particularly in multi-threaded tasks and gaming. The GPU within the Snapdragon 730G also provides a superior graphical experience.
Battery Life
Both devices share an endurance rating of 156 hours, indicating comparable battery life under similar usage patterns. However, the Samsung Galaxy M51’s 25W wired charging capability, completing a full charge in 115 minutes, is a significant advantage over the Coolpad Cool 6’s unspecified charging speed. The M51 also offers reverse wired charging, a feature absent on the Cool 6, allowing it to function as a power bank for other devices.
Buying Guide
Buy the Coolpad Cool 6 if you need a functional smartphone for basic tasks like calling, texting, and light social media use, and your budget is extremely limited. Buy the Samsung Galaxy M51 if you prefer a smoother user experience, better gaming performance, a brighter and more enjoyable display, and faster charging, even if it means spending a bit more.
Frequently Asked Questions
❓ Is the Snapdragon 730G in the Galaxy M51 powerful enough for modern mobile games?
Yes, the Snapdragon 730G is a capable mid-range chipset that can handle most modern mobile games at medium to high settings. While it won't match the performance of flagship chips, it provides a smooth and enjoyable gaming experience, especially considering the price point of the M51.
❓ Does the Coolpad Cool 6 suffer from significant performance throttling during extended gaming sessions?
Given the Helio P70’s 12nm process and less sophisticated thermal management compared to the Snapdragon 730G, the Coolpad Cool 6 is more likely to experience performance throttling during prolonged gaming. This means the phone may reduce its clock speeds to prevent overheating, leading to a drop in frame rates and a less responsive experience.
❓ How does the charging speed of the Samsung Galaxy M51 compare to other phones in its price range?
The 25W charging on the Galaxy M51 is relatively fast for its price range. Many competitors in the budget segment offer 15W or 18W charging, meaning the M51 will charge significantly faster, reaching 100% in approximately 115 minutes.
❓ Is the battery life of the Samsung Galaxy M51 affected by its brighter display?
While the brighter display does consume more power, the Galaxy M51’s large battery capacity and the power efficiency of the Snapdragon 730G chipset help to mitigate this effect. The phone still achieves an impressive endurance rating of 156 hours, comparable to the Coolpad Cool 6.
