It appears we are getting some concrete updates on the upcoming OnePlus flagship. New leaks around the OnePlus 15 are giving us a clearer picture of what to expect from the next flagship. According to famous tipster Digital Chat Station on Weibo, the phone could pack a huge battery, super fast charging and a refreshed design with a flat display.

In case you’re wondering, OnePlus is expected to skip the “14” just like it skipped the “4” in the past because the number is considered unlucky in some Asian cultures. So, the brand is likely jumping straight to the OnePlus 15 after the OnePlus 13. In any case, here’s what we know about the phone.

Digital Chat Station says the OnePlus 15 prototype is based on the SM8850 chip likely the upcoming Snapdragon 8 Gen 4 (possibly called Snapdragon 8 Elite 2). The phone is being described as performance-focused, so don’t expect massive upgrades to the camera, though there could still be some tweaks.

One of the standout features could be the battery, which reportedly “starts with a 7” suggesting a 7,000mAh+ capacity. That’s huge by flagship standards. It’s also tipped to support 100W wired and wireless charging. Despite this large battery, OnePlus is aiming to keep the design slim and lightweight.

The OnePlus 15 is expected to feature a flat display, a shift from the curved panels we’ve seen since the OnePlus 7 Pro. The screen could be a 6.78-inch LTPO OLED with 1.5K resolution and ultra-thin bezels, made possible by LIPO packaging technology. This helps create a symmetrical and clean front look.

The phone is said to include a 0916 vibration motor for better haptics, a single-point ultrasonic fingerprint sensor and a fibreglass back panel. For protection, it will offer IP68/IP69 dust and water resistance.

As of now, OnePlus is A/B testing two versions of a 50MP triple camera system. Both setups include a main sensor (one standard, one ultra-large), an ultra-wide camera and a periscope telephoto lens with around 3x zoom. OnePlus is reportedly deciding between small and medium sensor sizes for the periscope unit.

The China launch for the OnePlus 15 is expected around October 2025, followed by a global release in January 2026.
