Why is the battery life of a smartphone shown the least amount of improvement year to year in comparison to other specs (processor, display, data speed)?

Smartphone batteries are getting better, smaller, and increasing in capacity.  The thing is that all those fancy huge displays and powerful processors require more power to run them.  So even though the battery capacity is increasing, the demand for power is also increasing, hence why you don't see huge leaps in battery life like you do in processor power.
