Here I will teach you how to make your mobile charge wirelessly without opening it or avoiding warranty, also without having extra size or weight!
Another thing is that you will be taught how to move electricity wirelessly for bigger projects, DIY plans can guarantee 10 cm of distance, for small mobile plans it can guarantee same distances that Nokia Lumia and other mobiles has.
Another advantage is that these plans are easy to understand and simple to make, they are cheap also! hardware costs around 35$ for mobile charging circuits, and even much less for other projects circuits!
