I have a little theory for that. Pyrrha said that he has a lot of aura after seeing him automatically healing himself without knowing, this could mean that the amount of aura he possess is above average or that because he has a lot, it's stronger but comes in small amounts. For example, in Naruto anime, the guy has a huge amount of chakra but since he doesn't know how to properly control it, he ends up using more than he needs and spends all of it in a couple of jutsus. Jaune could be doing the same, not to mention the possibility that the amount of aura that is use to absorb damage is a lot more than the amount you use for semblances or forcefields.

During his fight with Cardin, we don't know how long Jaune was fighting Cardin and during the Ursa battle: he got beat up by Cardin, used his semblance to protect and heal himself and took two strikes from an Ursa Major. And then, he went into the red zone. It took all of that, and if he didn't got beat up, he could have easily use more abilities before spending all of it.

Maybe the reason is simply that he is always getting beat up. The other characters normally don't take strikes so they save that aura for their semblances.
