I asked my wife, she's the camera bug. We took it for a 2 week trip to Maui about a month or so ago. Her reply was plenty. She took a backup and didn't need it and believe me the camera got a workout. Like our Amex Card, we didn't leave home w/o it.
Hi Theresa! I think you can use the camera for one day long taking picture. The battery isnt the problem for me, but I can tell you that I am not very satisfied with the quality and the resolution of the pictures. I have another Nikon, more professional, and It is much better than this coolpix. I think you have to buy this coolpix just if you want for taking picture under the water or in the beach or something like that.
I went on vacation for 5 days shortly after I purchased it and only had to charge it twice. As far as actual hours at a time, I couldn't tell you but it was turned off and on and used to take pictures and video repeatedly between 8 am and 8 pm. It never fully died, I just charged it whenever I noticed it was less than halfway.
