- Potentially larger battery capacity (unconfirmed)
- Weak performance with the MediaTek Helio G37
- Inferior camera quality
- Limited software support and updates
Display Comparison
The Pixel 7a boasts a significantly brighter display, reaching a measured peak of 1070 nits, compared to an assumed lower brightness on the BLU S91 Pro (typical of its price bracket). While the S91 Pro’s panel specifications are unavailable, the Pixel 7a’s brightness ensures excellent visibility outdoors. The Pixel 7a likely utilizes an OLED panel, offering superior contrast and color accuracy, while the S91 Pro likely uses an IPS LCD. The Pixel 7a’s 90Hz refresh rate (not specified, but standard for the line) would also provide a smoother scrolling experience than the S91 Pro’s likely 60Hz panel.
Camera Comparison
The Pixel 7a’s camera system is a major differentiator. While specific sensor details are not provided, Google’s computational photography prowess, powered by the Tensor G2, elevates image quality significantly. The Pixel 7a excels in low-light conditions and offers features like Magic Eraser and Photo Unblur. The BLU S91 Pro’s camera capabilities are likely more basic, relying on hardware alone. Without detailed specs, it’s safe to assume the S91 Pro’s image processing won’t match the Pixel 7a’s sophistication. The Pixel 7a’s video recording capabilities will also be superior, benefiting from the Tensor G2’s image signal processor.
Performance
The performance gap between these devices is substantial. The Google Pixel 7a’s Tensor G2 (5nm) features a tri-cluster configuration with 2x2.85 GHz Cortex-X1 cores, 2x2.35 GHz Cortex-A78 cores, and 4x1.80 GHz Cortex-A55 cores. This is a significant leap over the BLU S91 Pro’s MediaTek Helio G37 (12nm) with its 4x2.3 GHz Cortex-A53 and 4x1.8 GHz Cortex-A53 cores. The Tensor G2’s more advanced architecture and smaller manufacturing process (5nm vs 12nm) translate to significantly higher processing power and improved energy efficiency. The Pixel 7a will handle demanding tasks like gaming and video editing with ease, while the S91 Pro will likely struggle with anything beyond basic apps.
Battery Life
The Pixel 7a has an endurance rating of 76 hours, indicating good battery life. It supports 18W wired charging with PD3.0 and 7.5W wireless charging. The BLU S91 Pro’s battery capacity is unknown, but given its price point, it’s unlikely to match the Pixel 7a’s endurance. The Pixel 7a’s faster charging speeds will also be beneficial, allowing for quicker top-ups. While the S91 Pro may offer a larger battery capacity, the Tensor G2’s efficiency could offset this advantage.
Buying Guide
Buy the BLU S91 Pro if you prioritize absolute affordability and need a functional smartphone for basic tasks like calls, texts, and light social media use. You’re willing to compromise on performance, camera quality, and long-term software support. Buy the Google Pixel 7a if you value a smooth user experience, exceptional camera performance, timely software updates, and access to Google’s AI features, even if it means spending more upfront.
