The bar left the battery out because it belongs to whoever knows the hardware, and had no way to take it back in. i3status-rust now renders bar-neutral blocks through its template; the power module contributes the battery where the machine reports one and the power draw where something measures it, sampling the root-only energy counter as root and publishing only a rate. The memory block shows what programs hold, the figure memory-pressure judges by, instead of counting the cache as used.
