OnePlus is set to launch the 15R on December 17, alongside the Pad Go 2 and Watch Lite. Ahead of the official release, the company has confirmed that the 15R features a 7,400mAh battery, marking the largest battery capacity ever in a OnePlus device sold outside of China. (The recently announced Ace 6T holds the record within China, equipped with an 8,300mAh cell.)
This substantial battery supports 80W SuperVOOC wired charging and is engineered to retain at least 80% of its original capacity after four years of use. It also incorporates 15% silicon content in its anode to enhance durability and efficiency.

Additionally, OnePlus has disclosed that the 15R is powered by the Snapdragon 8 Gen 5 SoC and features an AMOLED display with a "1.5K" resolution and a 165Hz refresh rate. The screen can reach up to 1,800 nits in High Brightness Mode. The device will also support OnePlus' Plus Mind feature and includes the Plus Key for enhanced user interaction.
