BLU M7L
- Potentially lower price point
- Simple and straightforward user experience
- Reliable for basic smartphone functions
- Likely limited software updates
- Potentially lower build quality
BLU G51S
- Potentially better software optimization
- Slightly more modern feature set
- May offer a marginally improved camera experience
- Slightly higher price
- Similar CPU performance to the M7L
Display Comparison
Both the BLU M7L and G51S lack detailed display specifications in the provided data. Given their price point, it's reasonable to assume both utilize IPS LCD panels. Expect 720p+ resolution as standard. The absence of information regarding refresh rates suggests both are likely capped at 60Hz. Bezels are expected to be substantial on both devices, maximizing screen real estate within a compact form factor. Color accuracy will likely be standard for this segment, prioritizing power efficiency over color fidelity.
Camera Comparison
Camera details are sparse for both devices. Without sensor size or aperture information, it's difficult to make definitive claims. However, given the price bracket, expect primary cameras in the 8-13MP range. Image processing will likely prioritize speed over detail, resulting in acceptable photos in good lighting conditions. The inclusion of secondary cameras (often 2MP macro or depth sensors) is common in this segment, but their utility is limited. The G51S *may* benefit from slightly more advanced software algorithms, potentially leading to marginally better image quality.
Performance
Both the BLU M7L and G51S are powered by the same Octa-core 1.6 GHz Cortex-A55 CPU. This indicates similar processing power for everyday tasks like web browsing, email, and social media. The Cortex-A55 architecture is focused on efficiency, meaning neither phone will excel in demanding games or resource-intensive applications. RAM capacity, which is not specified, will be a key determinant of multitasking performance; more RAM will allow for smoother switching between apps. Thermal management is unlikely to be a significant concern given the CPU's low power draw.
Battery Life
Battery capacity is not specified for either device. However, given their similar hardware and target market, expect capacities in the 3000-4000 mAh range. Charging wattage is also unknown, but likely falls within the 10-15W range. Real-world battery life will depend heavily on usage patterns, but both phones should comfortably last a full day with moderate use. The lack of fast charging support means a full charge will likely take several hours.
Buying Guide
Buy the BLU M7L if you need a basic, reliable smartphone for essential tasks like calls, texts, and light social media browsing, and are prioritizing absolute lowest cost. Buy the BLU G51S if you prefer a device with a potentially more refined software experience, and are willing to spend a small premium for features like a potentially better camera and slightly improved performance in demanding apps.
Frequently Asked Questions
❓ Will either of these phones receive Android updates?
Given BLU's track record and the price point of these devices, significant Android version updates are unlikely. Expect security patches to be infrequent, if provided at all. These phones are best suited for users who are comfortable with the initial Android version they ship with.
❓ Are these phones compatible with all US carriers?
BLU phones generally support a wide range of GSM carriers, but compatibility with CDMA carriers (like Verizon and Sprint) can be limited. It's crucial to check the specific model's supported bands against your carrier's network before purchasing. Verify compatibility using the carrier's online compatibility checker.
❓ How well will these phones handle popular apps like WhatsApp and Facebook?
Both the M7L and G51S should handle apps like WhatsApp and Facebook without significant issues. However, running multiple apps simultaneously or using resource-intensive features within these apps may result in slowdowns due to the limited RAM and processing power.
