Closed Cell

Does a razor cell phone use power when it’s closed?

Is it like a computer, when it’s on hybernate, or sleep? Will I lose battery power if it is flipped closed?

Yea of course you will (lose battery power). When a cell phone is turned on but has a closed screen, it’s still using power continue to stay in “on” mode. Otherwise if opened the screen nothing would happen. A closed cell phone is exactly like a computer that’s in sleep mode.
