- OnePlus has locked in March 24, 19:00 CST for the 15T launch, but as of March 23, the company’s China store pages hadn’t posted the final retail price.
- Company teasers highlight a 6.32-inch device packing a hefty 7,500mAh battery, paired with a 165Hz screen for faster refresh, the Snapdragon 8 Elite Gen 5 processor, and a periscope zoom camera.
- China’s smartphone market is losing steam just as the launch arrives, and with memory prices climbing, some Android makers are already nudging device costs higher.
OnePlus is set to launch the 15T in China on March 24, aiming to squeeze a hefty 7,500mAh battery into a relatively compact 6.32-inch flagship. That 7,500mAh spec shows how much juice the battery can store.
The clock is ticking, with conditions turning more challenging for the market. According to Reuters, Apple managed a 23% jump in China smartphone sales through the first nine weeks of 2026, even as overall sales slipped 4%. Android competitors have begun pushing up prices on certain models, responding to higher memory costs.
OnePlus sees an obvious gap: pack a bigger battery into a device that stays in the compact flagship range. Samsung’s Galaxy S26 has a 6.3-inch screen and a 4,300mAh battery. Over at Xiaomi, the Xiaomi 15 bumps things up to a 6.36-inch display with 5,240mAh.

According to the latest teasers, the 15T is expected to ship with 100W wired charging and 50W wireless, plus a 3.5x periscope telephoto—basically, a zoom lens that uses folded optics to fit inside the device. The phone’s also picking up an alphabet soup of protection: IP66, IP68, IP69, and IP69K, covering everything from dust to water spray, submersion, and high-pressure jets.
OnePlus is pushing boundaries on battery size this year. The official OnePlus 15 page puts the new device at 7,300mAh, a jump from last year’s 13T, which featured a 6,260mAh battery in a nearly identical 6.32-inch frame.
OnePlus has started taking reservations on both its China website and OPPO’s online store, though as of March 23, the price remains unlisted. That missing price tag is still the main question mark for the launch.
It’s all about price risk here. In February, IDC projected a 12.9% drop in global smartphone shipments for 2026, with average selling prices jumping 14% as memory shortages start to hit. IDC vice president Francisco Jeronimo didn’t hold back—he called it a “tsunami-like shock.” Meanwhile, Nabila Popal described the situation as a “structural reset” for the industry. According to Counterpoint, cited by Reuters last week, China’s smartphone market is expected to remain pressured through May. Reuters
