@ck@chaos.social It absolutely is free - provided your program is not doing anything idiotic. The Android notion of "sent to sleep" is not needed to *actually* sleep, which is a POSIX notion and a much better design. A task which is blocked on poll() does not use any more battery than one that doesn't exist at all, and it uses *less* than one that Android has "sent to sleep" because there is zero overhead to restart it on the event when it arrives.
