A couple of things I leaned in taking my photography class to learn how to use mine was: Turning your digital screen off as you take the pics. Just use the view finder like the "old" cameras and it won't drain your battery. Also, you can go into your menu and reformat your camera - it deletes all of the pics you have stored so download your pics before hand. Its called "re-fragmenting" or "reformatting" on most cameras and will clear up space on your cameras hard drive (even though you delete your pics it still leaves something in your camera that takes up space). You can also change the setting on the quality of your pictures that you take. You do not need to have it on the best quality setting (unless you're a professional or are going to blow up the pictures to portrait size) and that will drain your battery life as well. Like another poster also said by new rechargeable batteries as they do wear out after a while! Hope this helps - if not then call your camera manufacturer - they're really great over the phone and will help you fix it for free!
