Appearance of new technology every single day in today's world is not some strange phenomena. The current trend shows new devices created to help and ease people's life, however, is still lacking in some factors which include Computing. Many had faced with issues of the battery lifetime, power drain due to overcharging and others. Even though there are some applications that claimed can help users to avoid the decreased of the problem but still users need to manually do the prevention such as unplugging the charger when the battery is full. Thus, this paper will present a development of an internet of things (IoT) device which can communicate with a mobile application to help people in handling their electronic appliances. The appliance integrated with an application that able to automate process, monitor the charging activities and apply mechanism to prevent an overcharging with some pre-setting value. Initial study received positive feedback thus support the development of this project. It gave beneficial to the society and simultaneously reduce the rate of producing the Li-ion battery waste in the world. © 2019 Published under licence by IOP Publishing Ltd.
