An avergae 800mah lion battery has about 375 charging cycles available, the worst thing that will shorten your battery life is charging it for an hour at home, jumping in your car and charging it for a half hour, getting to work and charging it for another few hours, you just very likely used/wasted 3 cycles there alone. Also leaving your phone on while charging it will not directly do harm but for many phones while its on and charging everytime you get a call, a text, an alarm/alert, etc... your losing an extra cycle. Im just offering advice as there can be many more factors involved in battery life.
