OnePlus is rumored to be prepping a compact flagship that could shake up the small-phone market. Leaks for the OnePlus 15s — the global sibling of the China-only OnePlus 15T — point to flagship silicon, huge battery capacity, and a long-missed ultra wide-angle camera.
Small body, big specs: what the leaks show
The freshest tip, shared on X by @gadgetsdata, describes a device with a 6.3-inch flat OLED panel at 1.5K resolution and a likely 120Hz refresh rate. That display size keeps the 15s in the compact flagship category while upgrading visual fidelity over many smaller competitors.
Under the hood: flagship performance
Expect top-tier performance: sources claim the OnePlus 15s will use Qualcomm's Snapdragon 8 Elite Gen 5, the same high-end SoC powering the OnePlus 15. That should deliver excellent CPU and GPU performance for gaming, multitasking, and AI-assisted features.
Biometrics and display tech
Moving beyond last year’s optical in-display fingerprint reader, the 15s is tipped to adopt an ultrasonic fingerprint scanner under the screen — faster and more reliable in varied lighting and wet-finger conditions.

Battery life and camera upgrades that matter
Perhaps the most eye-catching leak: a mammoth battery. A recent listing for the OnePlus 15T suggested a 7,000mAh+ cell, and while the global 15s may be marginally smaller (similar to how the OnePlus 13s trimmed capacity versus the 13T), it still hints at class-leading endurance.
For context, Xiaomi’s new Xiaomi 17 launched in China with the same flagship chip and a 7,000mAh battery, so OnePlus appears to be following a trend toward ultra-long battery life in flagship phones.
Finally: an ultra wide lens
OnePlus fans will also welcome a returning camera element: an ultra wide-angle lens. The OnePlus 13T/13s lacked a dedicated ultra wide module, so adding this lens to the 15s would restore more flexible shooting options for landscape, group shots, and creative framing.
How it stacks up and what to expect
- Display: 6.3-inch flat OLED, 1.5K, ~120Hz
- Chipset: Snapdragon 8 Elite Gen 5
- Biometrics: ultrasonic in-display fingerprint
- Battery: rumored around 7,000mAh (may vary by region)
- Camera: upgraded with an ultra wide-angle lens
Imagine a compact phone that lasts two days on a single charge without sacrificing flagship performance — that’s the promise these leaks suggest. OnePlus seems to be betting that many users still want smaller handsets but aren’t willing to lose battery life or camera versatility to get them.
As always with pre-release tips, details could change before launch: capacities, final display specs, and camera setups often differ between Chinese and global models. Still, the OnePlus 15s rumor cycle is shaping up into one of the more interesting small-phone stories of the year.
