No. But there are chemical changes involved in the battery, if that's what you mean.

When using a phone, you are using electrical energy. The phone's battery converts stored chemical energy into electrical energy to power the device.
No.

No.
A chemical change. If the identity of of the chemicals involved change in identity, it is a chemical change.
It dies a slow death until it's put back in the phone and charged. If it's a phone your not using all the time taking out the battery when not in use will prolong the charge.
If your phone dies fast you may need to get a new battery. You should turn off all running applications that you are not using to save on battery power.
A battery is an example of chemical energy because it stores energy in the form of chemical potential energy, which is released through a chemical reaction when the battery is used. The reaction between the chemicals inside the battery produces electrical energy that can power devices.
No, it is a chemical change.
Energy transformations in a phone occur primarily when it is charged and used. When plugged in, electrical energy from the outlet is converted into chemical energy stored in the battery. During usage, this chemical energy is then transformed into electrical energy to power the phone’s components, such as the display and processor. Additionally, when using apps or making calls, some of this electrical energy is converted into sound and light energy.
