As new smart phones are released shortly after the other, previous mobile phones are being disposed.
There are lead and cadmium inside mobile phones and these cause soil pollution. Therefore, there is an
increase in the number of users who wish to apply the remaining batteries. However, knowledge about
complex circuit is needed to use this so it is difficult for ordinary people to use it if they are not professionals.
Therefore, a eco-friendly device is to be suggested to prevent disposed batteries from causing soil pollution
and for ordinary people to apply batteries even without holding specialized knowledge.
