BLU F91

  • Significantly faster performance
  • Modern chipset (Dimensity 810)
  • Faster charging (18W wired, 10W wireless, reverse wired)
  • Likely better camera performance
  • More responsive user experience

  • Potentially higher price than S91 Pro
  • May lack some niche features found on higher-end phones

BLU S91 Pro

  • Lower price point
  • Adequate for basic tasks
  • Decent battery life

  • Slow performance
  • Outdated chipset (Helio G37)
  • Slow charging
  • Likely inferior camera quality
  • Less responsive user experience

Display Comparison

Both phones likely feature similar display technology (likely IPS LCD) and resolution (likely FHD+). However, the F91 might have a slightly brighter display and potentially a higher refresh rate (though this is unconfirmed). The S91 Pro's display will likely be adequate but may lack the vibrancy of the F91.

Camera Comparison

While both phones likely have multiple rear cameras, the F91's more powerful chipset should translate to better image processing and potentially improved low-light performance. Expect the S91 Pro's camera to be adequate for casual snapshots but lacking in detail and dynamic range.

Performance

This is where the F91 shines. The Dimensity 810 is a substantial upgrade over the Helio G37. Expect significantly faster app loading times, smoother gaming, and better overall responsiveness on the F91. The S91 Pro will struggle with demanding apps and multitasking.

Battery Life

Both phones likely have similar battery capacities (around 5000mAh). However, the F91's 18W wired and 10W wireless charging offer a significant advantage over the S91 Pro's likely slower charging speeds. Reverse wired charging on the F91 is a bonus.

Buying Guide

The BLU F91 is ideal for users who prioritize performance, smooth multitasking, and faster charging. The BLU S91 Pro is a better fit for those on a very tight budget who primarily need a basic smartphone for calls, texts, and light social media use.

Frequently Asked Questions
