All batteries will eventually wear down and store less charge over time. There are, however, some measures you can take to keep your battery in top shape.
Batteries lose capacity over time due to two factors: The first is the constant electrochemical interactions that occur inside the battery, even when at rest; the second, more significant one is the act of charging itself. Lithium ions expand when charging and contract when discharging, and high volumetric expansion causes degradation of the battery. Scott Mullin, a former Apple intern currently working in R&D at Seeo, a next-generation battery startup, compares the chemistry to breathing, saying "The deeper the breaths that you make it take, the more damaging that can be."
The main thing you can do to extend your battery's life is to follow one simple rule of thumb: ABC, or "Always Be Charging". The battery's typical Depth of Discharge, or DOD, is directly related to how many cycles it will take before its capacity drops to 80%. The more you have to charge your battery before it's full, the less full charge cycles you'll get out of it.
You'll also want to calibrate once a month by running the device until the battery causes it to shut off, then charging to full. This will help ensure that the indicator always reports an accurate reading.
The temperature and charge level at which you store your phone also matter: Lithium ion batteries run best when stored at colder temperatures at around half charge. This is because all chemical reactions speed up at higher temperatures, including the ones which naturally degrade batteries over time. Unless you live in Ecuador, however, temperature shouldn't make much difference over the typical life of a mobile device. Just remember to avoid leaving your phone in your car on hot summer days.
