Okay, I don't know if this was intentional or not, so I'm putting it here instead of the Bugs board.
Basically, I am wearing a quantum helmet.. that has absolutely no charge left in it... yet my food meter remains "full" (as full as the suit will fill it), and I can still breathe underwater. Oh yeah, and it's still providing me with 1 point of armor.
So... is it supposed to do all of that without any charge left? 
Are you sure it's actually empty? And not just "display bar empty but still some energy left"?
It had been "empty" for well over an hour... it still is empty... and it's still displaying said functionality. I suppose, on the bright side, it's not auto-refilling, right? 
[EDIT]
My pants have finally decharged (been a minecraft day) and I had been watching them for some time now while fighting monsters and taking damage... I have not lost the 2.5 armor points that they give me. I suppose, on the bright side, it's not auto-refilling, right?
1. Armor display bar is bugged either way, ignore it.
2. Even discharged pieces do provide a few points of armor. Try engaging fights with a set of discharged Armor, it should absorb some % of the damage.
3. Damn it.
