Is energy in a cell phone transferred from outside home or already stored in cell phone?
Energy in a cell phone primarily comes from the battery stored within the device. When you charge the phone, electrical energy from an external power source is transferred to the battery, converting that energy into chemical energy for storage. The phone then uses this stored energy to operate when not connected to an external power source. Additionally, during use, the phone can also draw energy from nearby signals, but the primary energy source remains the battery.
