Cellphones use Electrical made from chemical reaction in the battery installed in the cellphone
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.
Carbohydrates
Electrical energy is used to charge a cell phone. When you plug your phone into a charger, the electrical energy is converted into chemical energy stored in the phone's battery. This chemical energy is later converted back into electrical energy when you use the phone.
Electrical energy is the type of kinetic energy that powers a cell phone. When you charge your phone, electrical energy is stored in the battery and converted to power the device when in use.
potential electrical energy
Cell phones do not directly use chemical energy; instead, they rely on electrical energy to function. However, the batteries in cell phones, typically lithium-ion, store chemical energy that is converted into electrical energy when the phone is in use. This process allows the phone to operate, making chemical energy indirectly essential for its functionality.

ATP
Cells use ATP (adenosine triphosphate) as their immediate energy source.
sunlight
Cells, like humans, cannot generate energy without locating a source in their environment.
The direct source of energy in a cell is adenosine triphosphate (ATP). ATP is produced through cellular respiration, which converts nutrients from food into a form of energy that the cell can use to carry out its functions. ATP releases energy when its phosphate bonds are broken, providing the necessary energy for cellular processes.
