Battery info current always 0

Hi all
I wanted to report a problem regarding consumption in milli amperes ..
In Battery mode the consumption goes out in 0, all the time
and in charge mode, also all the time at 0, it does not show the charge current of the battery nor the consumption ..
klwp-pro: 3.39b911019
Phone: SM-J730
Android: 9

As additional data another software called, ampere, if it shows the consumption in battery mode and in charge mode.

the script that the friend J.S proposes, it worked for me, only that it delays or is a bit late the update of the data
