Power versus time required to A) melt tricosane B) melt tricosane and increase its temperature by 40°C, C) melt tricosane and increase its temperature and that of the entire handset 40°C, and D) melt tricosane and increase the temperature of the tricosane, Al PCM container, 1/3 of the ABS case and 1/3 of the FR-4 by 40°C. (Calculations were done assuming zero heat transfer to the ambient.)
