OnePlus 15T Boasts 7,500mAh Battery in Compact Form

OnePlus has confirmed key specifications for its upcoming compact smartphone, the OnePlus 15T, highlighting a substantial 7,500mAh battery that exceeds the capacity of its larger flagship counterpart. The device, teased by company president Li Jie Louis on Weibo, is positioned as a smaller variant of the OnePlus 15, which launched at the end of 2025, and is expected to debut in China later this month.

The OnePlus 15T's battery employs silicon-carbon technology under the Glacier branding, a structure similar to that in previous models but with 200mAh more capacity than the OnePlus 15's 7,300mAh cell. This upgrade aims to deliver exceptional endurance in a compact form, particularly for its 6.3-inch display. Li Jie Louis emphasized the importance of robust battery life in small-screen flagships, stating via translation, "Our goal is simple: small-screen flagships shouldn't compromise on battery life." The phone supports 100W wired charging and 50W wireless charging, allowing for rapid recharges of the large battery. It also includes bypass charging, which helps prevent overheating during extended gaming sessions by directing power directly from the charger.
