The upcoming Flipkart Big Billion Days Sale 2025, starting on September 23, is set to bring massive discounts across categories, and smartphone deals are expected to be the biggest highlight. Among them, Nothing has officially confirmed an exclusive upgrade offer for its loyal users. The Nothing Phone 3, which debuted earlier this year at a starting price of ₹79,999, will be available for as low as ₹34,999 during the sale — but this offer comes with a special condition.

Special Upgrade Offer for Nothing Phone 1 & Phone 2 Owners

Nothing Co-Founder Akis Evangelidis revealed via X (formerly Twitter) that owners of Nothing Phone 1 and Nothing Phone 2 can upgrade to the Nothing Phone 3 at a heavily discounted price during the Flipkart sale. Through exchange deals, eligible users will be able to grab the device at just ₹34,999, making this one of the biggest upgrade programs by the brand.

Evangelidis emphasized that this is a one-time, limited-period offer, exclusively available during the Big Billion Days Sale 2025 on Flipkart.

Pricing Details and Configurations

The Nothing Phone 3 launched in India with two storage variants:

12GB + 256GB model – ₹79,999

16GB + 512GB model – ₹89,999

Thanks to the exchange bonus, Nothing Phone 1 and Phone 2 users can cut down the effective price significantly, making it the most affordable way to switch to the company’s latest flagship.

Why the Upgrade Offer Matters

The Nothing Phone 1, launched in July 2022 with Android 12-based Nothing OS, will not be receiving the Nothing OS 4.0 (Android 16) update. This makes the upgrade offer especially beneficial for Phone 1 users who want access to long-term updates and the latest features.

Meanwhile, the Nothing Phone 3 ships with Android 15-based Nothing OS 3.5 out of the box but has already been confirmed to get the Android 16-based Nothing OS 4.0 update.

Nothing OS 4.0: What’s New?

Nothing has been teasing the upcoming Nothing OS 4.0 update, built on Android 16, which will soon roll out to Phone 3 users. The company has previewed a refreshed UI design with:

Redesigned circular icons

A new red torch icon

Updated Bluetooth switch & dark mode button

A revamped brightness control slider

A rumored temperature monitor widget

Currently, Nothing is running a Closed Beta program of Nothing OS 4.0 on the Phone 3, allowing selected users to test features, report bugs, and provide feedback before its public rollout.

Flipkart Big Billion Days 2025: Early Access

The Big Billion Days Sale 2025 begins on September 23, but Flipkart Plus and Black members will likely get early access to the biggest deals. Since the Nothing Phone 3 offer is expected to be time-sensitive and limited in stock, early access members could have an advantage in availing of the ₹34,999 upgrade price.

Conclusion

The Nothing Phone 3 Flipkart Big Billion Days 2025 offer is a golden opportunity for existing Nothing Phone 1 and Phone 2 users to upgrade at nearly half the original cost. With its premium hardware, Android 16 update promise, redesigned Nothing OS 4.0, and strong ecosystem integration, the Phone 3 becomes an attractive flagship at an unbeatable price point.

If you are a Nothing loyalist, this could be the best time to upgrade before the limited-period offer runs out.
