Touch HD3 — best battery ever made?

I've been reading on my HD3 for the last week and I realized the battery is still at 51% — and then it occurred to me that I still haven't charged it for the third time yet (and it didn't come fully charged). It was delivered in late January, so six months now... and still at 51% charge? (I think the last time I charged it was in April or May... maybe March?)

Curious to know if others are getting this kind of battery life from their HD3s? It's just weird.
