The Mute+ATMOS combination button press to determine the Battery Status was originally designed for production line testing, not for consumer usage.  We determined that this testing method was inaccurate and began testing using specialized external equipment.  As of Software Version V21.13.11.80, the ability to check Battery Status inaccurately has been removed.

When charging the satellite speakers you can be confident that the Battery Status is 100% when the LED indicator goes  out.  As well, when the LED begins blinking red, you are at 20% and should recharge or plug in your speakers.
