The official launch is still days away, but for all intents and purposes, the OnePlus 15 is already here. A massive new leak has just laid bare nearly every detail of OnePlus’s next flagship phone, and it’s shaping up to be an absolute monster. We’re talking about a battery that could redefine endurance and the most powerful chip Qualcomm has to offer.
The new flagship is expected to debut on October 13th, but based on details from tipster Lao Chen Air, we have a clear picture of what’s coming.
A Big, Bright, and Buttery-Smooth Display
The OnePlus 15 will reportedly feature a 6.78-inch curved screen with a sharp 1.5K resolution. The panel is said to support a 1Hz–165Hz adaptive refresh rate, which should make everything from scrolling social media to gaming feel incredibly fluid. With HDR10+ support and a peak brightness of 1,800 nits, you should have no trouble seeing the screen even in direct sunlight.
A Battery That Could Finally End Battery Anxiety
This is the showstopper. The leak points to a massive 7,300mAh battery, which would be one of the largest ever seen in a mainstream flagship phone. For context, that’s nearly 50% larger than the batteries in many of today’s top devices.
When you do need to top up, the phone will support blazing-fast 120W wired charging and convenient 50W wireless charging. This combination could make the OnePlus 15 the new champion for power users who never want to see a low-battery warning again.
New Cameras, Moving Beyond Hasselblad
Eariler we reported that OnePlus’s high-profile partnership with camera maker Hasselblad is over. Now, the company is betting on its own in-house DetailMax Engine to handle image processing.
Here’s the rumored camera setup:
- Main Camera: A 50MP LYT-808 sensor with a 24mm f/1.8 lens and optical image stabilization (OIS).
- Telephoto Camera: A 3.5x optical zoom lens (85mm equivalent) with an f/2.8 aperture and OIS for clear, stable zoom shots.
- Ultrawide Camera: A 0.6x lens (15mm equivalent) with an f/2.0 aperture.
Everything Else We Expect
- Top-tier water and dust resistance (IP66/IP68/IP69 rating)
- An ultrasonic in-display fingerprint scanner
- The latest UFS 4.1 storage for faster app loading
- USB-C 3.2 for quick file transfers
- NFC for mobile payments

Bottomline
If these leaks prove to be true, the OnePlus 15 isn’t just another yearly update. The combination of the next-generation Snapdragon 8 Elite Gen 5 processor and that colossal 7,300mAh battery could make it one of the most powerful and longest-lasting phones of the year.
While we wait for the official launch on October 13th to confirm the final details, one thing is clear: OnePlus is swinging for the fences.
