Inspiration of this design comes from the growing process of plants in nature; plants can get energy through photosynthesis. This idea can be used in the dorsal housing of phone batteries. The phone can be charged without electricity. Solar panel and nutritious liquid which is appropriate to the growth of plants will be installed in the dorsal housing. Sowing one seed, then it will be slowly growing in the dorsal housing. It will charge for the phone when the seed grows. The plant constantly absorbs sunlight and nutrients to grow up, when it becomes a certain size, users can transplant it to breed continuously.
