The OnePlus 15 is gearing up for its launch in China this October, and leaks have already revealed plenty about the upcoming flagship. The device is set to succeed last year’s OnePlus 13 and is expected to introduce major upgrades in both hardware and software.
One of the most talked-about changes is the end of OnePlus’ five-year partnership with Hasselblad, with the company shifting to its self-developed DetailMax Engine for imaging.
Camera
For years, OnePlus has leaned on its Hasselblad collaboration to strengthen its camera game. Now, with the OnePlus 15, that chapter has ended. CEO Pete Lau confirmed the company’s in-house DetailMax Engine, which aims to deliver sharper, more realistic photos with improved clarity.
The OnePlus 15 is rumored to sport a 50MP triple-camera setup, paired with this new engine. Early reports suggest that the DetailMax Engine will enhance skin tones, low-light photography, and dynamic range, positioning OnePlus as a true competitor in the imaging space.
Display
The smartphone is expected to feature a 6.78-inch flat LTPO display with 1.5K resolution and a blazing-fast 165Hz refresh rate.
According to leaks, this screen will be BOE’s third-generation “oriental” panel, already claimed to be a leader in global display rankings. If true, this could give the OnePlus 15 one of the best displays in the smartphone market.
Battery
Battery performance looks to be another major highlight. The OnePlus 15 could ship with a 7,000mAh (or higher) battery, far above the industry average for flagships.
Paired with 100W wired fast charging, the handset may offer both endurance and speed, making it a go-to device for power users.
Design
Leaks suggest a redesign for the rear camera housing. Unlike the circular modules of past models, the OnePlus 15 could arrive with a square-shaped camera island. Combined with its premium flat display, this design update might give the phone a bolder, more modern look.

Hasselblad
OnePlus’ collaboration with Hasselblad is officially over—at least for smartphones. The brand has confirmed that while Hasselblad won’t be involved in the OnePlus 15’s cameras, future partnerships in imaging projects could still happen.
This move signals OnePlus’ push toward independence in imaging technology. With the DetailMax Engine being several years in the making, all eyes are on how well it can perform against competition from Apple, Samsung, and Google.
The OnePlus 15 is shaping up to be a powerhouse device—combining top-tier display tech, an enormous battery, and a bold step forward in camera innovation.
