It's hard to say. I do have an S95, and I've only drained the battery to the red once. That was no where near 200 shots, but as I stated, it's tough to evaluate. First, all manufacturers overstate battery life when compared to real world performance. Second, usage pattern matters - going out and shooting 200 shots at a time is not common, I expect. More commonly, one would go out and shoot a few dozen shots, again a day or a few days later, etc. Personally, I do have 2 batteries and I swap them out frequently. The time I nearly ran out of power, I had grabbed the camera when I was running late, and it had sat unused for a couple of weeks after a day or two of use, and I neglected to swap in the fully-charged battery. Li-ion batteries self-discharge, so a few days drops the charge level several percent. If you get in the habit of charging after every shooting day, I think you'd be fine.
