dumpsys battery in Termux

I am trying to get battery info in Termux. I granted android.permission.DUMP and android.permission.PACKAGE_USAGE_STATS via ADB for com.termux (Termux app) Then I opened Termux and types in /system/bin/dumpsys battery. It displays this error message:

Can't find service: battery

and exits with code 0. I can confirm that I can get those info via ADB using the same command (e.g. getting battery level with /system/bin/dumpsys battery | grep level) Am I missing some permissions for Termux app? Or are there some more fixes? Please help. Edit: I am aware of the existence of termux-battery-status command in Termux. It's output is not too informative. So I will not accept answers telling me to use the command.
