- 25W wired charging is slow and no charger is included in box
Samsung Galaxy S24 Ultra
₹99,999
Pros

- Built-in S Pen enables document annotation, sketching, and precise text selection
- Anti-reflective Gorilla Glass Armor dramatically reduces glare versus standard glass
- Titanium frame keeps the phone rigid and premium, comparable to iPhone Pro
- Galaxy AI features like Circle to Search, Generative Edit, and Live Translate add tangible daily value
Cons
- At 232g it is the heaviest S-series phone — extended one-hand use causes fatigue
- 45W charging is competitive but not fast compared to Chinese flagship phones at ₹1L
- Price of ₹99,999 is a premium — the S25 Ultra at ₹94,999 offers a newer chip for less
- QHD+ at this brightness, combined with the large display, reduces battery endurance under heavy use
