Well, I'm not so strict as to say charging with power off every night, and doing so every night will lead to reduced battery longevity over time (500 charges or less before it will only hold 70% of its original capacity). That may not be a big problem for MAXX users, and depending on how soon you replace it, may not really be an issue at all, but would probably be a big issue for RAZR users and those who will have their phones for 2 or more years.
I recommended doing power-off charges either only when you absolutely need the maximum staying power, and during meter trainings.
