Understanding mobile phone battery - Human interaction for developing world A perspective of feature phone users in Africa

Mobile phone battery is well recognized as an open usability concern for both device manufacturers and end users. Due to the ubiquitous nature of mobile phones, battery related problems have received increasing attention in the scientific conferences. In our paper, we have presented the need for understanding and investigating Human Battery Interaction for Development (HBI4D). In our study we are mainly interested in the non-smartphone or feature phone users who belong from low income; low literacy and resource limited areas. This would enable us in understanding the existing design opportunities available for developing and designing energy efficient mobile battery solutions for emerging markets. Our work is first of its kind as almost all the existing work on battery efficiency is targeted towards smartphone users from western world. However, our work mainly comprises of users from emerging markets such as India, China and South Africa.
