[0002]Kinetic energy harvesting has the potential to at least partially address this challenge. Battery powered devices are often portable. Indeed, many such devices easily fit within a pocket or purse and experience continued motion over relatively long periods of time. Associated with that motion is acceleration in numerous directions, which acceleration causes masses of various elements within the device to impose a variety of forces. If a significant portion of the energy associated with those forces can be converted to electrical energy, such electrical energy could be used to at least partially recharge the device battery.

My watch self-charges in this manner with a rotating weight inside that drives a micro-generator and hasn't needed a battery change yet (7 years and counting).
It'd be great if this works for phone batteries but it is hard to see how enough meaningful current could be produced, especially when you consider the space lost to this additional mechanism/electronics - this presumably will impact on the space for the battery cells themselves?

"A battery for an electronic device is contained within a first frame that is coupled to a second frame by one or more piezoelectric elements. The second frame is coupled to a device chassis by one or more additional piezoelectric elements. In response to translation and/or rotation of the electronic device, portions of forces induced by the battery mass are transferred to the piezoelectric elements. Electrical energy output by these piezoelectric elements is received in a power controller and can be applied to the battery. Additional device components can also be contained within the first frame so as to increase the total mass that induces forces applied to the piezoelectric elements."
