Battery Specifications and Capacity
The Bose Quietcomfort Ultra Earbuds are equipped with a high-capacity lithium-ion battery. Each earbud contains a 60mAh cell, while the charging case provides an additional 300mAh. This setup allows for extended listening sessions without frequent recharging.
Battery Life Under Typical Usage
In standard usage scenarios, users can expect approximately 8 hours of continuous playback on a single charge. The charging case offers an extra 24 hours of battery life, enabling multiple recharges before needing to be plugged in.
Impact of Features and Settings on Battery Life
Activating features such as active noise cancellation (ANC) and transparency mode can reduce battery life by approximately 20%. Using the earbuds at higher volume levels also shortens playback time. Conversely, turning off ANC and lowering volume can extend battery duration.

With ANC turned on, the earbuds provide about 6 hours of playback. The charging case still offers an additional 18 hours, making it suitable for long trips or daily use.
Battery Life with ANC Disabled
Disabling ANC extends playback to approximately 8 hours. This setting is ideal for users seeking longer listening sessions without sacrificing sound quality.
Charging Time and Efficiency
The Bose Quietcomfort Ultra Earbuds charge rapidly. A full charge takes about 1.5 hours when using the included USB-C cable. The charging case itself can be recharged via wireless charging or wired connection, providing convenience for different scenarios.
Tips to Maximize Battery Life
- Turn off earbuds when not in use.
- Use ANC selectively to conserve power.
