OnePlus appears to be gearing up for the next expansion of its flagship smartphone lineup in India. Following the recent launch of the OnePlus 15R as a more performance-focused alternative to the flagship OnePlus 15, a third device — believed to be the OnePlus 15s — has now surfaced on India’s Bureau of Indian Standards (BIS) certification website.

This development strongly suggests that OnePlus is preparing to introduce another premium smartphone in the Indian market, likely positioned between the core flagship and the performance-oriented R-series model.

BIS Certification Confirms India Launch Preparations

A new smartphone carrying the model number CPH2793 has been listed on the BIS certification database. While the listing itself does not reveal specifications, design details, or hardware features, BIS approval is a mandatory step for any smartphone before it can be officially sold in India.

According to tipster reports circulating on social media, particularly from X user @kpgc10kai_, this model number is believed to correspond to the upcoming OnePlus 15s. If accurate, this confirms that the device has cleared regulatory hurdles and could be launched in India in the near future.

OnePlus 15s Expected as the Third Flagship Variant

If the BIS listing indeed belongs to the OnePlus 15s, the device will become the third model in OnePlus’ current flagship lineup, joining the OnePlus 15 and the OnePlus 15R. This strategy mirrors OnePlus’ recent approach of offering multiple flagship-tier devices catering to slightly different user needs, such as compact performance, camera-centric features, or premium design.

The OnePlus 15s is widely expected to succeed the OnePlus 13s, which debuted earlier this year as a refined flagship option with a balanced focus on performance, display quality, and camera capabilities.

Looking Back: OnePlus 13s as a Reference Point

Since official details about the OnePlus 15s remain scarce, the OnePlus 13s provides a useful reference to understand where the upcoming model could be positioned.

The OnePlus 13s was launched in India in June with the following pricing:

12GB RAM + 256GB storage – ₹54,999

12GB RAM + 512GB storage – ₹59,999

It was offered in premium finishes such as Black Velvet, Green Silk, and Pink Satin, reinforcing its flagship identity.

Display and Performance Expectations

The OnePlus 13s featured a 6.32-inch LTPO display with a 1.5K resolution, adaptive refresh rate up to 120Hz, and peak brightness of up to 1,600 nits. Powering the device was Qualcomm’s Snapdragon 8 Elite chipset, ensuring top-tier performance for gaming, multitasking, and everyday use.

If OnePlus follows a similar strategy with the 15s, the new model could retain a compact yet premium display, while potentially upgrading processing power, efficiency, or display technologies in line with the latest flagship standards.

Camera and Battery: Potential Areas of Focus

In terms of photography, the OnePlus 13s offered a strong dual-camera setup with a 50MP Sony LYT-700 main sensor and a 50MP telephoto lens, along with a 32MP front camera for selfies and video calls.

Battery performance was handled by a 5,850mAh battery with 80W SuperVOOC fast charging, delivering a balance between endurance and fast top-ups. The OnePlus 15s could build upon this foundation with camera refinements, improved image processing, or enhanced battery longevity.

What to Expect From the OnePlus 15s

While OnePlus has not officially confirmed the OnePlus 15s yet, the BIS certification listing strongly indicates that the device is in advanced stages of preparation. The smartphone is expected to sit in the premium flagship category, likely offering:

Flagship-grade performance

A refined display experience

Advanced camera hardware

Fast charging and long-term software support

More concrete details regarding specifications, pricing, and launch timeline are expected to surface through teasers or official announcements in the coming months.

Conclusion

The appearance of the OnePlus 15s on the BIS certification website marks a key step toward its official debut in India. With the OnePlus 15 and OnePlus 15R already covering different segments of the premium market, the upcoming OnePlus 15s could further strengthen the brand’s flagship portfolio.

As competition intensifies in India’s premium smartphone space, OnePlus seems poised to offer users more choices within its high-end lineup. All eyes are now on the company’s next move as anticipation builds around the OnePlus 15s launch.
