Even a high end smartphone is useless without battery. So the life of the phone- the battery is inevitably important to us. How about jogging and charginh your phone from the kinetic energy you are you are producing. So this is the vision of Nokia at present ans it also posted a video in context to that.

Nokia posted a video which shows its vision to raise awareness about sustainability.
