Some technology is programmed to go into a low power “standby” or “sleep” mode instead of actually turning off. Most smart phones these days don’t actually shut all the way down. They’re only *mostly* off.

Most modern electronic devices don’t really turn all the way off unless you completely disconnect the power. Instead they’ll switch into a standby mode where basically everything is turned off except a clock that will trigger the rest of the computer to start back up.
