A battery or the energy that flows from your house to your charger!?!

Answer : Conversion Energy.
A cellphone produces electromagnetic energy in the form of radiofrequency radiation to communicate with cell towers. This energy is used to transmit and receive signals for voice calls, texts, and data transfer.
A cellphone converts electrical energy from the battery into electromagnetic energy to send and receive signals to communicate with cell towers. Additionally, the screen and processor use electrical energy to display information and run apps.

A cellphone battery converts chemical energy into electrical energy. When the battery is connected to a device, the chemical reactions within the battery generate the flow of electrons that powers the device.
When a cellphone is turned on, electrical energy is used to power on the device and convert it into the various forms of energy required for its functioning: radio frequency (RF) energy for communication with cellular networks, light energy for the screen display, and thermal energy due to the device's internal components operating.

No, a cellphone charger and chloroplasts do not have the same function. A cellphone charger converts electrical energy from a power source into a form that can recharge a battery, enabling the phone to operate. In contrast, chloroplasts are organelles in plant cells that perform photosynthesis, converting light energy into chemical energy in the form of glucose. While both are involved in energy transfer, their roles and mechanisms are fundamentally different.
A cellphone primarily uses electrical energy from its battery to power its various components such as the screen, processor, and antenna. When the phone is being charged, it also draws electrical energy from an external power source, such as a wall outlet or a portable charger.
Electrical energy, which is then in turn converted into sound, among other things.
