Marty cooper is a former Motorola engineer who on April 3, 1973 placed the first phone call made using a mobile phone. Motorola DynaTAC 8000x is the name of the device with which a colleague called and informed him that he was talking to him using a wireless device. 1.13 KG weighing the device that Cooper used back then, almost 10 times more than most smartphones available on the market today, but at that time everything was so revolutionary, nobody cared yet.
From then until now mobile phones have become smaller, more beautiful, more sophisticated, many have hardware almost as good as that of a laptop, but they all have one big problem, the battery. Probably in 40 years smartphones will look completely different, or they will disappear completely, but for now they are the pinnacle of technology for mobile communications.
