What would a backup/restore alter *total usage* on phone

[chefwong]

Did a restore and the total usage went from 0 hrs to 4 days, x hrs...

One would expect the cumultive usage counter to reflect true hardware usage, regardless of backup or not....

yeah, basically the usage indicator on the iPhone is completely useless. You'll see a lot of people on here get kind of frazzled about it, but really it is useless.
