Pricing starts at Rs 129,999 for the base 256GB variant, with higher storage options available.
Design and Build
Both the S24 Ultra and S25 Ultra feature premium titanium frames, but there are subtle differences in dimensions and ergonomics:
  • S24 Ultra:
    • Dimensions: 162.3 x 79.0 x 8.6mm
    • Weight: 232g
    • Frame: Titanium

Both phones have a glass front and back, with the S24 Ultra using Corning Gorilla Glass Victus 2 and the S25 Ultra upgrading to Corning Gorilla Armor 2, which offers improved scratch resistance and durability. Both models maintain an IP68 rating for dust and water resistance, ensuring robustness.
Display
The display is a critical factor for many users, and the S25 Ultra brings noticeable enhancements:

  • S24 Ultra:
    • Chipset: Qualcomm Snapdragon 8 Gen 3 for Galaxy

However, the S25 Ultra introduces Wi-Fi 7 for faster connectivity, compared to the S24 Ultra’s Wi-Fi 6E. Neither model includes a 3.5mm headphone jack, reflecting the trend toward wireless audio.
Conclusion
The Samsung Galaxy S25 Ultra offers several meaningful upgrades over the S24 Ultra, making it a compelling choice for those looking to upgrade or buy a new flagship phone. Key improvements include a larger, brighter, and more glare-resistant display, a more powerful and efficient chipset, enhanced camera performance with better low-light capabilities, and the latest software with advanced AI features. The design is also more ergonomic, enhancing user comfort.
While the S24 Ultra remains an excellent device, especially for those who already own it and are considering an upgrade, the S25 Ultra’s advancements make it the better option for those seeking the latest technology and future-proofing. For users in India, the S25 Ultra is now available following its launch on January 22, 2025, and can be purchased through Samsung’s official website or authorized retailers.
This detailed comparison should help users make an informed decision based on their needs, whether they prioritize display quality, performance, camera capabilities, or long-term software support.
