This document provides information about smartphones by discussing their hardware components. It defines a smartphone as a mobile phone combined with a computer and various sensors and wireless inputs/outputs. The document then describes some of the key hardware components of smartphones, including the application and connectivity processor chips, memory, antennas, batteries, and radio frequency chips. It provides Apple iPhone 4S and Samsung Galaxy SIII as examples and outlines their specific processors, memory, power amplifiers, and other components.
![Li-ion Battery
3.7 [V]: used for bias of active
devices (amplifiers, mixers, …)
This voltage should be small to
consume smaller power (P = I x V)
5.3 [Whr]: unit for energy (W x hour)
