Imho even if you would charge overnight you wont notice any difference untill your phone is EOL. Even if you would treat your liion battery like a princess it would still die in ~5 years (please correct me if im wrong).
Even though this is only my personal experience and your mileage may differ, but im currently using a HTC HD2 which is still going strong on its first battery. I plug it in almost every night before i go to bed.
Edit: and I must add that really your phone is designed to be used like this. If you only have 70% left and you really need that extra juice the next (few) day(s) because you wont have a charger with you, just plug it in as you go to bed.
If you really go out of your way to rape your battery every day, just buy a new one when its EOL, if you haven't gotten a new device already.
