Battery decay threshold
It is immensely beneficial for the Lithium-Ion battery health to set upper charge limit of lets say 80-90% meaning the battery will charge only to that % value - because charging every time to full 100% is putting unnecessary wear on the battery and reducing its capacity over time faster.

The other method is "low threshold, varied decay" to set threshold at a low or the lowest value for maximum IF gain, and then use the decay control to adjust, starting from the slowest setting of 5 dB/s and working upward. As decay goes faster, it introduces clipping. When listening to a weak signal with threshold low, advance the decay until
