Smartphones continue to become more high-performance, but as a result, they put a strain on the battery and tend to get hot. If you're worried about your smartphone getting hot, you might want to try applying this sheet to enhance heat dissipation. ☆TIPS☆ If the smartphone's temperature exceeds 55℃, the processing speed will significantly decrease. By applying this sheet, which enhances heat dissipation performance, the aluminum absorbs heat and lowers the temperature, reducing the burden on both the smartphone itself and the battery. T133-13-B
