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

Chemical change
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.
Chemical change
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.
It is a physical change, as the chemical integrity remains the same.
