(a) is the schematic diagram of the experimental setup and (b) is the isometric view of the container adhered to the mobile electronic device. The temperature of the container was measured with an accuracy ±0.5 °C by the five T-type thermocouples located in the center of outside surface of the container indicated in (b). The sizes of the heater, container and PCM are 26.2 mm × 20.2 mm × 5 mm, 40 mm × 40 mm × 3.5 mm, and 39 mm × 35 mm × 2.5 mm, respectively. The mass of the PCMs, heater and container was  g for gallium, 5.057 g for sodium sulfate decahydrate, 2.689 g for N-eicosane, 3.105 g for paraffin, 6.2 g for the heater, and 13.4 g for the container, respectively. Depending on the chip set, the heating power ranges from 1 to 3.5 W.

Figure Legend:
Temperature curve with different PCM filled in the container. Throughout the experiment, the ambient temperature was kept around 22 °C. The temperature data were obtained by five T-type thermocouples with locations indicated in Fig. 1(b), and the temperature curve was plotted with the mean value of the data.

Figure Legend:
Temperature curves of mixed PCM and mixed gallium and SiO2 subject to 3 W heating and subsequent natural cooling. Throughout the experiments, the ambient temperature was kept around 20 °C. The temperature data were obtained by five T-type thermocouples with locations indicated in Fig. 1(b), and the temperature curve was plotted with the mean value of the data.

Temperature holding time for the gallium PCM under different heating powers. The heating power was calculated with 1.0 V × 1.06 A for 1 W, 1.2 V × 1.32 A for 1.5 W, 1.4 V × 1.49 A for 2 W, 1.5 V × 1.64 A for 2.5 W, 1.7 V × 1.76 A for 3 W and 1.8 V × 1.96 A for 3.5 W. Throughout the experiment, the ambient temperature was kept around 20 °C.
