- Shorter battery life compared to S5 Pro
- 15W charging is relatively slow
- Potentially higher price
Display Comparison
The Infinix S5 Pro features a display with a 1677:1 contrast ratio and a measured peak brightness of 336 nits. While adequate for indoor use, this brightness falls short of modern standards and will struggle in direct sunlight. The A51 5G UW’s display specifications are not provided, but Samsung typically employs Super AMOLED panels known for vibrant colors and excellent contrast. Given Samsung’s market position, it’s reasonable to expect a superior viewing experience on the A51 5G UW, particularly outdoors. The S5 Pro’s contrast ratio, while respectable, won’t match the infinite contrast of an AMOLED display.
Camera Comparison
Both phones are listed as having photo and video capabilities, but detailed camera specifications are lacking for the Infinix S5 Pro. Given its price point, it likely features a basic camera setup. The Samsung Galaxy A51 5G UW, while not a camera powerhouse, benefits from Samsung’s image processing expertise. Without specific sensor details, it’s difficult to make a direct comparison, but the A51 5G UW is likely to produce more consistent and higher-quality images, particularly in challenging lighting conditions. The absence of detail regarding the S5 Pro’s camera suggests it’s not a key selling point.
Performance
The performance gap between these two devices is substantial. The Infinix S5 Pro’s MediaTek Helio P35 (12nm) utilizes older Cortex-A53 cores, resulting in a CPU that is significantly slower than the Qualcomm Snapdragon 765G (7nm) found in the A51 5G UW. The Snapdragon 765G’s Kryo 475 cores, with their varying performance tiers (Prime, Gold, Silver), offer a much more efficient and responsive experience, especially when multitasking or running demanding applications. The 7nm process node of the Snapdragon also contributes to better thermal efficiency, reducing the likelihood of performance throttling under sustained load. The A51 5G UW is demonstrably the faster and more capable device.
Battery Life
The Infinix S5 Pro boasts an impressive endurance rating of 106 hours, indicating exceptional battery life. This is a significant advantage for users who prioritize longevity. The Samsung Galaxy A51 5G UW, with its 15W wired charging, will likely require daily charging, especially with 5G usage. While the A51 5G UW’s battery capacity isn’t specified, the more powerful chipset and 5G connectivity will inevitably consume more power. The S5 Pro’s endurance rating suggests a larger battery capacity and/or more efficient power management.
Buying Guide
Buy the Infinix S5 Pro if you absolutely need a phone that can last two full days on a single charge and are willing to compromise on performance. It’s ideal for basic users who primarily browse, text, and make calls. Buy the Samsung Galaxy A51 5G UW if you want a smoother, more responsive experience with 5G connectivity, and are comfortable with potentially needing to charge your phone daily. This is the better option for media consumption, light gaming, and multitasking.
Frequently Asked Questions
❓ Is the Helio P35 in the Infinix S5 Pro sufficient for playing modern mobile games?
The Helio P35 is a relatively weak chipset and will struggle with demanding games. While it can handle less intensive titles, you'll likely need to lower graphics settings and accept lower frame rates for most modern games. The A51 5G UW’s Snapdragon 765G offers a much smoother gaming experience.
❓ How much faster is 5G on the Samsung Galaxy A51 5G UW compared to 4G?
5G speeds on the A51 5G UW can be significantly faster than 4G, potentially offering download speeds several times higher. However, actual speeds depend on network availability and coverage in your area. Sub-6GHz 5G, which the A51 5G UW utilizes, offers a noticeable improvement over 4G, but not the extreme speeds of mmWave 5G.
❓ Does the Samsung Galaxy A51 5G UW support expandable storage?
While not explicitly stated in the provided data, Samsung phones in this price range often include a microSD card slot for expandable storage. This is a valuable feature for users who need to store a large number of photos, videos, or other files.
