BLU G51
- Very affordable
- Decent battery life
- Compact size (likely)
- Weak processor
- Limited performance
- Basic camera
- May experience lag
BLU S91
- Better performance than G51
- Octa-core processor
- Improved multitasking
- Likely slightly better camera processing
- Still a budget phone
- Camera quality is limited
- Display quality is basic
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 color accuracy due to its more modern chipset, but this is speculative without specific display panel details.
Camera Comparison
Camera specs are likely similar, potentially featuring a 13MP main sensor and a depth sensor. Image quality will be adequate in good lighting conditions, but expect noise and limited detail in low light. The S91's more powerful processor *could* allow for slightly better image processing, but the difference will be minimal.
Performance
This is where the S91 shines. The Helio G25's octa-core configuration offers a significant performance boost over the G51's quad-core Helio A22. Expect smoother multitasking, faster app loading times, and a more responsive overall experience on the S91. The G51 will likely struggle with demanding apps and multitasking.
Battery Life
Both phones likely have a battery capacity around 4000-5000 mAh. Battery life should be comparable, offering a full day of moderate use. The S91's more efficient chipset *might* provide slightly better battery life, but it's unlikely to be a significant difference.
Buying Guide
The BLU G51 is a good option for users prioritizing a very basic smartphone experience and extremely tight budget. The BLU S91 is better suited for those who want a slightly more responsive phone for everyday tasks, social media, and light gaming.
