As with any new technology, smartphones have not been without problems.  Not only have the systems sometimes had stability issues, but also the hardware and external factors have made some progress difficult.

When making a smartphone, the focus is almost always on size—either that of the phone as a whole, or that of the screen it possesses.  However, components can only be made so small.  Additionally, the smaller theses parts are, the more fragile they often become.<br />

Another problem is power.  The more equipment a phone uses, the more power it will tend to consume.  When a smartphone is designed to be small, it is difficult to supply it with a battery that will hold enough power for the phone to be practical.  When small, high-voltage batteries are used, they also tend to wear out quickly, requiring more frequent charging.  While motion and inductive charging methods are options being studied,<ref>https://www.nytimes.com/2014/02/03/technology/building-a-better-battery.html</ref> these methods have proven largely ineffective so far.  For these to work, the phone would need to be moved around much more that it ordinarily would be, or a large induction coil must be attached to gather any significant power from the surroundings.  While these strategies may be a part of the future, smartphones currently require a certain irreducible size of chemical battery.
