Abstract
The demand for higher performance and enriched user experience in mobile devices has steadily increased their power consumption over the past few years, a trend that rapidly outpaced the evolution of the Li-ion battery technology whose energy density simply could not keep up with the ever-increasing power demand. It is not uncommon for intensive users to charge their smartphones at least once a day if not twice. As it will be explain the recharging cycles lead to a deterioration of the battery performance that over time needs to be replaced. Nowadays battery life is among the biggest complaints among smart device users. It is understandable therefore that proper handling of the battery is becoming a hot topic in the engineering community particularly in light of the fact that more and more devices moved or are moving to non replaceable batteries. The paper will review the historical trend of battery technology and address battery and power management techniques aimed to increase battery life and safety with particular focus on smartphone and tablets

It is worth noticing that often times the 0Â % SOC is defined based on external conditions as for example the minimum operating voltage of the circuit supplied by the battery although some useful charge may still be available inside the cell.
