BLU consistently targets the budget-conscious smartphone user, but even within that segment, choices must be made. The G71+ and G51S represent two distinct approaches to affordability. The G71+ features a more powerful, though older, Cortex-A75 based CPU, while the G51S opts for the more power-efficient Cortex-A55. This comparison will dissect the implications of this core architectural difference and determine which device delivers the best overall experience.
🏆 Quick Verdict
For users prioritizing responsiveness and occasional multitasking, the BLU G71+ is the better choice. Its Cortex-A75 CPU provides a noticeable performance uplift over the G51S’s Cortex-A55. However, the G51S remains a viable option for basic smartphone tasks and those seeking maximum battery life.

Display Comparison
Unfortunately, display specifications are not provided. However, given the price point of both devices, we can anticipate both utilizing IPS LCD panels. The G71+’s slightly higher processing power *could* translate to better image processing for slightly improved color accuracy, but this is speculative. Bezels are likely comparable, and neither phone is expected to feature high refresh rate displays.
Camera Comparison
Camera details are absent, making a direct comparison difficult. However, given the market segment, both phones likely feature basic camera setups. The G71+'s more powerful CPU *could* contribute to faster image processing and potentially better low-light performance, but this is dependent on the image signal processor (ISP) within the chipset. We anticipate both phones will include a primary camera and potentially a depth or macro sensor, but image quality will likely be similar in good lighting conditions.
Performance
The core difference lies in the CPUs. The BLU G71+’s octa-core 1.8 GHz Cortex-A75 processor represents a significant step up in performance compared to the G51S’s 1.6 GHz Cortex-A55. The A75 is based on a more advanced architecture, offering greater IPC (Instructions Per Clock) and better overall responsiveness. While both are octa-core, the A75’s individual core performance is substantially higher. This translates to faster app loading times, smoother multitasking, and a more fluid user experience on the G71+. The G51S, while adequate for basic tasks, will exhibit more noticeable lag when handling multiple apps or demanding processes. RAM specifications are not provided, but the CPU difference will be the dominant factor.
Battery Life
Battery capacity and charging wattage are not specified. However, the Cortex-A55 in the G51S is inherently more power-efficient than the Cortex-A75 in the G71+. This means the G51S will likely offer longer battery life under similar usage scenarios. If battery life is a primary concern, the G51S has an advantage. Without knowing charging wattage, it’s impossible to assess 0-100% charge times, but the G71+’s more powerful CPU might benefit from faster charging if supported.
Buying Guide
Buy the BLU G71+ if you frequently switch between apps, enjoy light gaming, or need a phone that feels snappier overall. Its CPU architecture is better suited for demanding tasks. Buy the BLU G51S if your primary needs are calls, texts, social media, and basic web browsing, and you prioritize long battery life over raw performance. It’s a solid choice for a secondary device or first-time smartphone users.
Frequently Asked Questions
❓ Will the BLU G71+ handle popular games like PUBG Mobile or Call of Duty?
While the G71+’s Cortex-A75 CPU is more capable than the G51S’s, it’s still a budget chipset. Expect playable frame rates at lower settings. Demanding titles may require significant graphical compromises to maintain a smooth experience. Don't expect flagship-level gaming performance.
❓ Is the difference in CPU speed noticeable for everyday tasks like browsing and social media?
Yes, the difference is noticeable. The G71+ will feel snappier when opening apps, scrolling through webpages, and switching between tasks. The G51S will handle these tasks, but with a slight delay that can become frustrating over time.
❓ Which phone is better for someone who primarily uses their phone for calls and texts?
The BLU G51S is perfectly adequate for calls and texts. Its power-efficient CPU will contribute to longer battery life, making it a good choice for users with minimal smartphone needs.
❓ Does either phone support fast charging?
Unfortunately, charging specifications are not provided. It's likely neither phone supports particularly fast charging standards, given their price point. Expect several hours for a full charge.
