Battery Extension Tool: A study of smartphone battery demand and conservation modes

Date of Publication: 
2022 September

The project surveyed power controls that currently exist within current mobile operating systems and evaluated the battery demand of wireless devices, comparing typical operation with optimal battery operation while various accessibility apps are in use. These data were analyzed to develop recommendations for best practices for battery charge extension of wireless devices. A proof-of-concept, customizable user interface prototype app, the Battery Extension Tool (BET), was developed to allow users with disabilities to implement these best practices while retaining access to their accessibility software.
