OnePlus is essentially ignoring the "laws of physics" with the upcoming OnePlus 15T. According to a massive data dump from Digital Chat Station (DCS) on Weibo, this compact flagship is set to debut in April 2026 with a battery capacity that makes the iPhone 17 look like a toy.
Key points
- OnePlus 15T features a massive 7,500mAh silicon-carbon battery in an 8.5mm body.
- The 6.31-inch OLED LTPO screen supports a class-leading 165Hz refresh rate.
- Five memory variants will be available, topping out at 16GB RAM and 1TB storage.
- The camera system skips the ultra-wide lens in favor of a 50MP telephoto sensor.
- Launching in April 2026 with new colors: Relaxing Matcha, White Chocolate, and Pure Cocoa.
The Battery: Silicon-Carbon Magic
The headline is the 7,500mAh battery. Let’s put that in perspective: the phone has a 6.31-inch screen but carries more "juice" than most 7-inch tablets.
- The Tech: It uses the Silicon NanoStack (15% silicon content) seen in the flagship OnePlus 15.
- The Frame: Somehow, it stays thin at 8.5mm.
- The Trade-off: Say goodbye to wireless charging. OnePlus is prioritizing raw capacity and 100W wired speed over the bulk of induction coils.
Color and Memory: "Healing" Aesthetics
DCS revealed five different SKU configurations. We are looking at a range starting from 12GB/256GB all the way to a massive 16GB RAM and 1TB storage variant. The color names sound more like a café menu than a tech launch:
- Relaxing Matcha: A desaturated, earthy green.
- Healing White Chocolate: A matte, fingerprint-resistant cream.
- Pure Cocoa: A rich, dark brown with a textured glass finish.
Screen and Build: Speed Over Size
The display is a 6.31-inch OLED LTPO (1.5K). While the size is "compact," the speed is anything but—OnePlus is pushing a 165Hz refresh rate.

- Biometrics: It gets the high-end ultrasonic fingerprint sensor, not the cheaper optical ones found in the "R" series.
- Durability: Rated IP68/IP69, meaning it can survive high-pressure water jets and deep dunks.
- Processor: Confirmed as the Snapdragon 8 Elite Gen 5 (built on the 3nm node).
The Camera Twist
Just like the 13T, OnePlus is ditching the ultra-wide lens. It’s a bold move. You get a 50MP main (likely the Sony IMX906) and a 50MP Samsung JN5 telephoto. It’s clear they are betting on people wanting better portraits and zoom rather than wide-angle landscape shots.
