Pros and cons

Samsung Galaxy S21 FE 5G

₹22,464

Pros

  • At ₹22,464 it carries IP68 water resistance — extremely rare at this price in 2025
  • 177g weight is exceptionally light for a phone with these specifications
  • 32MP selfie camera with portrait video — still competitive for social media users
  • Wireless charging support is rare at this price point

Cons

  • Exynos 2100 has reached a performance ceiling — newer mid-range chips can outpace it in benchmarks
  • OS updates have ended (hit 4-year limit) — no longer receives Android version upgrades
  • No expandable storage — 256GB only
  • 25W wired charging is slow and no charger is included in box

Samsung Galaxy S25 Plus

₹89,999

Pros

  • QHD+ resolution makes this the sharpest-looking screen in the S25 lineup — ideal for media consumption and creators
  • 4900 mAh battery comfortably sees most users through 1.5 days of mixed use
  • 45W charging fills to 60% in around 30 minutes — meaningfully faster than the standard S25
  • Snapdragon 8 Elite handles everything — Ray Tracing gaming, 8K video, real-time AI — without breaking a sweat

Cons
