I want to see how other people with this little concern of my regarding the iPhone battery.

I have heard that the iPhone battery life (overall) is counted by the number of times it's charged, as opposed to how fully charged it is.

My question is, in the course of the day I plug and unplug my iPhone from my computer numerous times - to synch the iPhone with my home computer, to synch with my work computer, to download/upload stuff when away from wifi (at work).

Each time I plug it in, my iPhone gets charged...

So I'm worried about how this would affect the overall battery life of my iPhone.
I'm just wondering how other people are dealing with this, or whether I'm just worrying over nothing (ie. that it's not a big deal and in truth it doesn't really affect the battery life etc.)

Any feedback would be appreciated...
