I just wanted to point out that I still see many people discussing "priming" or wearing in cell phone batteries to get a better charge. This only applies to nickel-based batteries, NOT Lithium-Ion batteries which are used in cellphones (as well as laptops and many other portable devices).

If you want to learn about Lithium-Ion batteries and how to improve their lifespan, visit Battery University
