Power Draw
Input power goes to the on-board switching supply, which supplies the Huawei module
and other circuitry. The switching supply has about 90% efficiency, and the vast majority
of current typically goes into the Huawei module which is powered at 3.92 volts. Please
see the Huawei MU609 HSPA LGA Module Hardware Guide, which shows current
consumption in various states and which shows peak current of 2.5 amps and typical
steady state current depending on what mode the Huawei module is in. Roughly
speaking, the average current into the modem’s supply is equal to
1.11 x Huawei current x (3.92/Voltage_Into_Modem)
