Check the CHARGE indicator
If you feel the battery life is shorter than the times listed on the manual or the specification webpages, lower the speaker's volume and check if the battery lasts longer. When you use the speaker at a high volume (or a maximum volume), battery consumption may increase, and the battery life becomes shorter than the times listed on manual or specification webpages.
Charge your wireless speaker and check if the CHARGE indicator lights up. Refer to the speaker manual for information about the location of the indicator. Manuals are posted on your model support page.
Note: The image above shows where to find the CHARGE indicator of the SRS-XB22 Wireless Speaker.
