Battery
The 
main component of a mobile phone is the battery which can be recharged using a phone charger. Priority is given to phone chargers nowadays because energy is lost in a phone charger when it is in the non load condition which normally happens when the charger is left plugged consuming the power when the mobile phone is not connected. To manage this, the first five toppers of mobile manufacturing companies Samsung, Nokia, LG, Motorola and Sony Ericsson in November 2008, the top five mobile phone manufacturers Nokia, Samsung, LG, Sony Ericsson, and Motorola created a star rating method to mark the efficiency of their respective chargers when in the no-load state. These days there are many semiconductor companies like Power Integrations and Cam Semi which claim to offer fly back controllers using which five star standards is achieved. Earlier, mobile phone batteries were made from nickel metal hydride which was small in size and less in weight. Lithium ion batteries are used instead of nickel metal-hydride batteries because they are lighter and do not have much voltage depression. Lithium ion batteries are advanced to lithium polymer batteries because they are weightless and can be mould into any shape other than the usual cuboids shape. Experimentation with solar cells is being carried out these days to find out an alternative for the power resource.
