The operating power is low for smart phone and tablet. Thermal radiation, natural convection and thermal conduction from the casing is good enough for cooling.  The introduction of a nm-grade chip expands its function and also extends the battery life. However, the surface area of the heat source becomes limited. With 40 years of experience, we are familiar with the manufacture of ultra slim heat pipe or ultra slim vapor chamber. Spreading the heat flux onto the surface of heat pipe or vapor chamber lower the temperature difference between the chip and the external air.
