I spent levels 10 to 40 today, locked in a room with two cave spider spawners and a lot of horrible little things with too many legs.
My nanosabre needed to be recharged several times but at the end of the session my quantum boots, legs and chest had consumed only 1 damage level of energy. In another experiment, I waded into a lava pool with a fist full of empty cells and spent several minutes in there, collecting lava. When I wandered out, my quantum armour showed no dip in the charge level.
I would've expected the armour to require charging more often. Anyone else feel that the quantum armour is currently burning far less juice than it should be?
