How does tech keep time when shut off?


How can my phone with no cell service or wifi be shut off and turned back on to tell the correct time and date? Does my phone use battery while “dead” to keep some functions running?

Even if your phone says the battery is dead, it’s not actually dead; It just doesn’t have enough charge/voltage to run the main functions of the phone. But it does have enough power to keep the RTC (Real Time Clock) running.
