Heck no. You can expect a lot more than that. It would take hours to drain the battery under normal shooting of bursts here and there. I mean, you're not going to hold the shutter button down until the battery is dead. I've seen folks say that they get over 1,500 shots out of one battery charge during a day's shooting.
Also, I suspect you can make the battery last longer if you shoot in silent mode because you don't have to operate the mechanical shutter then.
