Today smartphones have become a requisite part of our daily life. Nowadays, there has been a rapid progress in developments of different modules of smartphones. This has led to increased energy consumption. Continual operation of smartphones causes decrease in battery runtime. On the other hand there has been relatively slow progress in charging and battery technology. It is the need of the hour to develop strategies to mitigate this problem. This article reviews different charging technologies and energy saving techniques that have emerged in the recent years. Wireless charging has emerged as a promising technique in charging of smartphones making charging fast, user friendly and eco-friendly. There have been developments in charging circuits of smartphones to minimize the losses. İt has become necessary to increase the efficiency of power delivery network (PDN) of smartphone platform. Modifications are being done in the PDN of smartphones. Different wireless networks have been studied and compared in this paper. Also, working of different PDN has been studied in detail.
