Display Comparison
Neither device boasts a particularly standout display. While specific display specs (resolution, panel type) are missing for the Infinix S5 Pro, its market positioning suggests an LCD panel. The Samsung A51 5G UW, similarly, doesn't specify advanced features like LTPO. The key difference lies in the processing power driving the display; the Snapdragon 765G's superior GPU will likely result in smoother animations and a more responsive touch experience on the Samsung, even if the raw panel specs are comparable. Bezels are likely similar, reflecting the mid-range nature of both devices.
Camera Comparison
The camera systems are difficult to directly compare without detailed sensor information beyond the megapixel counts. However, the Samsung A51 5G UW likely benefits from Qualcomm’s image signal processor (ISP) within the Snapdragon 765G, offering superior image processing capabilities. While the Infinix S5 Pro (16+32) suggests a 16MP main sensor and a 32MP front camera, the Samsung’s image processing algorithms will likely deliver more consistent and detailed results, particularly in challenging lighting conditions. The presence of OIS (Optical Image Stabilization) on the Samsung, if equipped, would further enhance image quality.
Performance
The performance gap between these two phones is substantial. The Samsung Galaxy A51 5G UW’s Qualcomm SM7250 Snapdragon 765G (7nm) is a far more advanced chipset than the Infinix S5 Pro’s Mediatek MT6765 Helio P35 (12nm). The Snapdragon 765G utilizes a tri-cluster architecture (1x2.4 GHz Kryo 475 Prime, 1x2.2 GHz Kryo 475 Gold, 6x1.8 GHz Kryo 475 Silver) offering a significant performance boost over the Helio P35’s octa-core (4x2.3 GHz Cortex-A53 & 4x1.8 GHz Cortex-A53). The 7nm process node of the Snapdragon also translates to better power efficiency and reduced thermal throttling, crucial for sustained performance in demanding applications. Gamers and power users will overwhelmingly benefit from the Samsung.
Battery Life
Battery life is a complex equation. While the specific mAh capacity of the Infinix S5 Pro is missing, its less power-hungry Helio P35 chipset could potentially offer comparable battery life to the Samsung A51 5G UW, despite the latter’s 5G capabilities. However, the Samsung’s 15W wired charging is a significant advantage, allowing for faster top-ups. The Snapdragon 765G’s efficiency improvements also contribute to better overall power management, meaning the Samsung can sustain performance for longer without significant battery drain.
Buying Guide
Buy the Infinix S5 Pro (16+32) if you need a very affordable smartphone for basic tasks like calling, texting, and light social media use, and 5G isn't a priority. Buy the Samsung Galaxy A51 5G UW if you prefer a smoother, more responsive experience, faster download speeds with 5G, and a more future-proof device, even if it means spending more.
Frequently Asked Questions
❓ Will the Helio P35 in the Infinix S5 Pro struggle with modern mobile games like PUBG or Call of Duty?
Yes, the Mediatek Helio P35 is a relatively low-end chipset and will likely struggle to deliver a smooth gaming experience in demanding titles like PUBG or Call of Duty, even at lower graphics settings. Expect noticeable frame drops and lag. The Samsung A51 5G UW’s Snapdragon 765G is far better suited for gaming.
❓ How much faster are download speeds on the Samsung A51 5G UW compared to the Infinix S5 Pro on a 5G network?
The Samsung A51 5G UW, with its integrated 5G modem, can achieve significantly faster download speeds on a 5G network compared to the Infinix S5 Pro, which lacks 5G support. Expect download speeds several times faster on the Samsung, potentially exceeding 100Mbps or even 1Gbps depending on network conditions.
❓ Is the 32MP front camera on the Infinix S5 Pro a significant upgrade over typical selfie cameras?
While 32MP sounds impressive, megapixel count isn't everything. The quality of the sensor, lens, and image processing algorithms are more important. Without further details, it's difficult to say if the Infinix S5 Pro's front camera is a substantial improvement. The Samsung A51 5G UW likely benefits from superior image processing thanks to the Snapdragon 765G.
