Life cycle.Mobile phones also referred to as wireless handsets, have been around for the last 40 years. In the four decades, they have undergone complete metamorphosis from the huge handsets with limited capability to the modern smartphones with unlimited capabilities (Cantu, 2016). The world’s first mobile phone hit the market on April 3, 1973. An engineer at Motorola, Martin Cooper, made the first call speaking through a mobile phone (Goodwin, 2016). The phone that Cooper used weighed about 1.1kig and was measuring 228.6x127x44.4mm in dimensions. The phone also took about 60 hours to fully charge and had only 30 minutes talk-time with that charge. The first commercial mobile phone was released by Motorola in 1983, Motorola DynaTAC 8000X. It had only 30 minutes talk-time, with six hours standby time, and has a memory for storing only 30 phone contacts. The cost was a staggering £2639 (Goodwin, 2016). Therefore, the first mobile phones were expensive but had low performance and capacity. They are regarded as the First Generation (1G) phones.
