When ANC is deactivated, the Buds 3 are projected to offer a battery life of 9 hours, mirroring the performance of the Buds Pro 2, and this extends to 33 hours with the charging case. With ANC activated, the battery life is estimated at 6 hours, extending to 22 hours with the case. Connectivity options will encompass Bluetooth 5.3, Google Fast Pair, and support for dual connectivity.

Although not officially confirmed, given the pattern observed with the Buds Pro 2 and OnePlus 11, the Buds 3 will probably make its debut alongside the OnePlus 12.
