Keeping iphone on Dock whole day is it bad?

Thanks

It's good to let your battery run down completely every now and then and then let it fully charge as maintains it's health. Same goes for laptops.

That's true for ni-mh batteries but not li-ion.

I've fully run it down 2-3 times now, planning to keep it docked most of the day when I'm in work now... hoping it won't affect the battery too much.

Leaving it plugged in shouldn't harm the battery at all since it fast-charges for the first 75-80% of capacity, then trickle charges (notice how the last bit of the meter takes a while to charge). You can tell how "hard" it's charging by how warm it gets. Once fully charged it will be powering the phone from the dock connector and giving the battery a tiny maintenance trickle every now and then.

In other words- don't worry about it
