Apple's patent register to Extend Battery Life

A patent from Apple about the new technology to increase battery life recently discovered by Apple Insider. Patent registration is intended to increase the energy density in Lithium rechargeable battery so it is more durable in use.
Apple investigating the use of a new technique called multi-step constant-current constant-voltage (CC-CV) which would increase the density of the volumetric and gravimetric energy in storing electric power in the battery. According to the patent, this method will increase the capacity of a battery without affecting the size of the battery and filling time.
Apple device when compared with other similar devices including a battery that is good enough. Even so battery power will be more and more in the future as new features continue to emerge, including a better screen that absorbs more energy than a regular screen. Therefore, devices with high battery life will always be needed and expected, either from Apple or from another company.
