I found my old reading glasses and looked at my shaky penmanship. The first test was 23. Hr. not 28. It was interesting because it showed a full battery charge on the display for a long time.

The 2nd RnB Battery test finished a short time ago. I checked it at about 19 hours and, like before, the Battery Display showed all black bars. However, it stopped its racked and died at 23 Hr. 18 Min.

I am sure if using Headphones, maybe a reduced Sensitivity, and searching for typical periodic time to allow self-refreshing, the RnB might give a longer total run-time. But for continuous audio EMI noise at full everything, 23+ Hours is very decent from this energy gobblet.
