WhatsApp(b) If the phone is being used, the dynamic power is P dynamic = (0.5)(10 −8 F)(1.2 V) 2 (3 × 10 8 Hz) = 2.16 W. Together with the static and broadcast power, the total active power is 2.16 W + 0.048 W + 3 W = 5.2 W, so the battery life is 6 W-hr/5.2 W = 1.15 hours. This example somewhat oversimplifies the actual operation of a cell phone ...
