BLU S91
- More powerful octa-core processor
- Better multitasking performance
- Potentially slightly better camera processing
- Likely more modern design
- May have slightly shorter battery life under heavy load
- Still a budget phone with limitations
- Display quality likely average
BLU G51
- More affordable
- Decent battery life
- Suitable for basic tasks
- Less powerful quad-core processor
- Slower performance
- May struggle with demanding apps
- Likely older design
Display Comparison
Both phones likely feature similar LCD displays, probably around 6.2 to 6.5 inches with HD+ resolution. Expect decent viewing angles but limited brightness. The S91 *might* have a slightly better panel due to potentially more modern components, but this is difficult to confirm without specific display specs.
Camera Comparison
Camera specs are often similar on budget BLU phones. Both likely feature a multi-lens setup (e.g., 13MP main + 2MP macro + depth sensor). Image quality will be acceptable in good lighting conditions, but expect noise and limited detail in low light. The S91's more powerful processor *could* lead to slightly better image processing, but don't expect a dramatic difference.
Performance
This is where the S91 shines. Its Mediatek Helio G25 chipset with an octa-core processor offers significantly more processing power than the G51's Helio A22 quad-core. Expect smoother app loading, better multitasking, and improved gaming performance on the S91. The G51 will handle basic tasks adequately, but may struggle with more demanding applications.
Battery Life
Both phones likely have batteries in the 4000-5000 mAh range. Battery life should be comparable, offering a full day of moderate use. However, the S91's more powerful processor *could* drain the battery slightly faster under heavy load.
Buying Guide
The BLU S91 is ideal for users who prioritize performance and multitasking, even on a budget. The BLU G51 is a good option for those primarily focused on basic tasks like calling, texting, and light browsing, and who are extremely price-sensitive.
