The S1 Pro uses a lithium-ion battery. Individual battery performance will vary due to battery age, storage conditions, and the number of charge cycles.
Bose does not guarantee how long a lithium-ion battery will retain its charge. However, we expect a fully charged battery in a new S1 Pro system will last 30 days with the power switch in the “Standby” (⏻) position if the system is using Firmware 7.1.5 or later.
After 30 days of non-use, the battery will enter Sleep Mode. Bose recommends that you wake up the battery and fully charge it at least once a year. If you leave it in Sleep Mode for longer than a year, the battery may completely discharge and become unusable.
- Bose recommends that you update your firmware to the latest version for the best performance. See S1 Pro Firmware Update for details.
- To wake up the battery from Sleep Mode, plug your S1 Pro into a power outlet and turn the power switch to the “On” (⏽) position. See S1 Pro Battery Sleep Mode for details.

March 19, 2019
Bose announced it could repair units that had this problem and asked customers with the issue to contact Bose to set up a repair order.
April 9, 2019
Bose announced it was still working on a fix and asked customers to hold onto their systems until the fix was in place.
Unfortunately, some customers had already sent in their systems to be repaired. Bose is working with those customers to ensure they have a unit to use while it resolves the repair issue.
