Is it OK to leave charging for long periods

[MMR]

Just wondered if its OK to leave my 3G charging all night every night, In other words leave it plugged into the dock, I am sure it is but just thought I would check what others think? could it over a while damage the battery? I have two docks, one is plugged into my Mac and the other is next to my bed plugged into the wall socket, I am using it as an alarm clock, so its plugged in all night.

It should be fine. About once a month you should let the battery drain all of they way too.

It will automatically stop charging when full, and bypass the battery to operate until undocked. Don't worry, nothing bad will happen if you leave it charging.

It's designed to be left in the dock. Battery stops charging automatically when charged and works from the wall power. I always hold my iphone on the dock.
