Updated: October 8, 2026 — prices checked during the live sales. Sale prices move fast; always confirm the final price on Flipkart / Amazon before buying.

The short answer: the best Diwali 2026 phone deals

Flipkart Big Billion Days (open to all from October 9, Plus members from Oct 8) and the Amazon Great Indian Festival (from October 8, Prime early access Oct 7) are both live for Diwali 2026. The standout deals this year: iPhone 17 at Rs. 79,999 (Rs. 77,999 with bank offers), Galaxy S25 Ultra at Rs. 84,999, Realme P4 Power at Rs. 29,999, and the brand-new Mivi One 5G at Rs. 11,999 as a Flipkart exclusive.

When do the Diwali 2026 sales end?

Flipkart Big Billion Days 2026 runs from October 9 to around October 15 (early access October 8 for Plus/VIP members). The Amazon Great Indian Festival started October 8 (Prime members got early access on October 7). Both sales stack bank offers: up to 10% instant discount on Axis and ICICI cards on Flipkart, and 10% instant off on SBI cards on Amazon. Diwali itself falls on Sunday, November 8, 2026 — but the biggest phone discounts land in these October sale windows, not in November.

Best flagship deals

1. iPhone 17 (256GB) — Rs. 79,999 (Rs. 77,999 with bank offers)

2. Samsung Galaxy S25 Ultra (12GB + 256GB) — Rs. 84,999
