Since mobile phones appeared, the common problem of all phones, especially smart phones  from generation to generation is that the  user can only use the phone for one or  two days because the battery life is so short. Just imagine if we are playing games or talking with friends and we are so excited with it; nonetheless, we are prompted that our phone is the condition of low battery. What a sad story!

Many years ago Motorola Company had thought about discovering a new source of energy to use in mobile phone like solar energy, and in 2007 the company issued a patent for an LCD (Liquid Crystal Display) which includes solar cells capable of charging the battery in a mobile phone and other portable device. This means that in the future mobile phone will be able to power itself and charge its internal battery by just only using sunlight.

In 2010, Samsung was the first company that produced the world’s first solar battery mobile phone called the solar Guru E1107 which will permit user to charge the battery anywhere that has the sunlight. With this new technology, user does not have to worry much about electricity to charge their mobile phone.

But just this year 2011, a new system devised by researchers at the University of Twente’s MESA and Institute of Nanotechnology places high-efficiency solar cells straight onto the electronics instead of the battery. By integrating photovoltaic cells directly into electronics, it could eliminate the need for even rechargeable batteries.

Also in January of this year, ARM and IBM announced that they had decided to extend their collaboration on advanced semiconductor technologies to enable the rapid development of the next generation mobile products. The objective is to create 14nm chips that will be even more suitable for better power management, longer battery life and better multimedia support.

Improvements in mobile phone battery life , will benefit users. Although we do not know when the development will be finished, it is clear that with this technological development it will be powering useful devices like mobile phones  more and more.
