Analyzing the indicators of innovative development of smartphones (the case of Nokia smartphones produced by Nokia, Microsoft, and HMD)

Subject. The article investigates the patterns of changes in technical and economic indicators of Nokia smartphones.
Objectives. Our purpose is to analyze technical parameters of mid-range Nokia smartphones.
Methods. The study rests on mathematical methods of research.
Results. The paper determines interrelations of technical and economic indicators of Nokia smartphones, demonstrates how the price and the specific absorption rate of electromagnetic energy depend on technological indicators and technical process, on which basis chipsets are made.
Conclusions. The development of smartphone manufacturing technology, as a rule, comes with rise in price and risks to human health, caused by an increase in the specific absorption rate of electromagnetic energy.
