Which guide did you follow? Try following this: - open terminal - type devel-su and press enter, then enter your root password and press enter. The beginning of the row should change from "bash-3.2$" to "bash-3.2#", that means you are now entering commands as root - type "systemctl stop tohd.service", exactly as it's written but without " ", then press enter - enjoy greatly enhanced battery life If I didn't understand wrong, with this command you just disable the TOH daemon for the current session, not permanently, so you'll have to do this at each reboot of the phone, or in other words, you can restore the default behaviour by just rebooting your phone (please anybody correct me if I wrote something wrong).
