This guy did some napkin calculations which show this kind of energy generation can barely keep up with the energy needs of a smart watch, let alone any kind of phone.
Compare Spring power to Lithium-ion (typical in rechargeable electronics, watches, laptops, phones etc)
Anyone know where I can find out about this?
