We have made giant strides in many of the elements found in our smartphones. The processors have incredible power, GPUs already allow you to enjoy mind-boggling games, the cameras make the DSLR no longer make sense for many and the screens have amazing resolution and quality. What fails again and again are the batteries, which do not move with the same speed.
In this scenario, it is true that we have enjoyed some changes: all components and technologies are now more efficient and “punish” less batteries, but besides that more and more manufacturers offer systems fast charge that now Google wants to unify. To complete in less time charging is one of the most attractive options of current smartphones, but curiously Apple have never talked about this option, and many wonder why.
