Smartphones (2000s)

---

The development of the smartphones was enabled by several key technological advances: The lithium-ion battery, an indispensable energy source enabling long battery life, invented in the 1980s and commercialized in 1991.

• The exponential scaling and miniaturization of MOSFETs (MOS transistors) down to sub-micron levels during the 1990s–2000s made it possible to build portable smart devices.
• The miniaturization also enables the transition from analog to faster digital wireless mobile networks.

In addition, the development of more mature software platforms that allowed mobile device ecosystems to develop independently of data providers. The figure on the right shows the components of an iPhone.

The figure below shows a typical system structure for smartphones, which includes the following six major components:

(i) a mobile operating system, (ii) a mobile central processor unit, (iii) a mobile browser, (iv) input and output devices and methods, (v) data storage, and (vi) batteries.
