- OnePlus has scheduled the 15T launch for March 24 at 19:00 CST, and its China store pages still did not show a final retail price as of March 23. 2
- Company teasers point to a 6.32-inch handset with a 7,500mAh battery, a 165Hz display that refreshes more quickly for smoother motion, a Snapdragon 8 Elite Gen 5 chip and a periscope zoom camera. 2
- The launch lands as China’s smartphone market weakens and rising memory costs push some Android brands toward higher prices. 3
OnePlus will unveil the 15T in China on March 24, trying to fit a 7,500mAh battery into a smaller 6.32-inch flagship phone. The mAh figure is a standard measure of how much charge a battery can hold. 2
The timing matters because the market is getting tougher, not easier. Apple’s China smartphone sales rose 23% in the first nine weeks of 2026 while the broader market fell 4%, Reuters reported, and Android rivals have already started lifting prices on some models as memory costs climb. 3
That leaves OnePlus chasing a simple opening: more battery in a phone that still sits in the smaller-screen flagship class. Samsung’s Galaxy S26 lists a 6.3-inch display and a 4,300mAh battery, while Xiaomi’s Xiaomi 15 pairs a 6.36-inch screen with 5,240mAh. 4
Li Jie, president of OnePlus China, has leaned hard into that pitch. In comments carried by Chinese media on March 21, he said many buyers think smaller phones are “born to compromise” and said OnePlus wanted battery life and performance that could beat larger handsets. 5
Recent teasers say the 15T will also bring 100W wired charging, 50W wireless charging and a 3.5x periscope telephoto camera — a zoom lens that bends light inside the phone to save space. It is also set to carry IP66, IP68, IP69 and IP69K ratings, shorthand for dust resistance and different levels of protection against water spray, immersion and high-pressure jets. 6
On battery size, OnePlus is even stretching past its own lineup. The official OnePlus 15 page lists a 7,300mAh battery, while last year’s 13T was marketed with 6,260mAh in a similar 6.32-inch body. 7
Reservations are already open on OnePlus’ China site and on OPPO’s store, but the listing still showed the price as to be announced as of March 23. For now, that is the biggest blank in the launch pitch. 2
The risk is straightforward: price. IDC said in February that global smartphone shipments could fall 12.9% in 2026 while average selling prices rise 14% as memory shortages bite; Francisco Jeronimo, an IDC vice president, called the squeeze a “tsunami-like shock,” and Nabila Popal said it marked a “structural reset” for the market. Counterpoint, cited by Reuters last week, expects China’s market to stay under pressure through May. 8
