Interesting. But are Fuze owners complaining about heat, battery life and dying while charging?

(I would REALLY like to get my hands on the datasheet and some application info!)
I am forced to draw upon another car analogy - the battery in a car is a requirement for a stable voltage output from the alternator due to the way a modern alternator works (PWM field current). If it has a PMIC, I don't see why it couldn't handle stabilizing any fluctuation in voltage from an external source. Any 5V charger is regulated itself, isn't it?
