How can a mobile switch itself on when it was switched off?

385 views

Some mobile phones have the option to schedule switch-off time and switch-on time. Switch-off time is understandable. But how can a mobile switch itself on, if it was completely switched off?

Does this imply that, even when the mobile is switched off, the screen is off and the hardware buttons are not responsive, the mobile is never really switched off?

They are never truly off, as long as any source of power is connected. Rather than switching off, they switch to so-called low power state, where most peripherials are switched off, the CPU is powered but basically performs no or very little operations and the Real-Time Clock chip sends a signal to “wake it up”.
