A phone uses electrical energy. But a phone is not electrical energy itself.
A phone also gives off sound energy and light energy (if it is a cell phone with a screen).
Your phone is probably best considered electrical energy, but you did not tell us the other options.
Phone uses DC 50V electricity energy to maintain its service.
