With strong reception for the OnePlus 13 series, the company is already gearing up for its next flagship. Rumours around the OnePlus 15 are picking up steam, with leaks pointing to major design changes, faster performance, and big battery life gains.

OnePlus 15: Expected Release Date & Name Choices
