I've got a Sony Cybershot (DSC W1). I like it well enough for the things I do with it, but it's become an energy hog. I was using rechargeables with it for the first few years (I bought it about four years ago) but I stopped using them because after recharging, they'd last only a short time compared to when I used them in the beginning. I thought the batteries had lost their recharge capacity. So I switched to ordinary commercial batteries for a couple of weeks. But the problem's the same. A couple of AA batteries lasts me for about 30 shots, no editing or archiving included.
Can an older camera become an energy hog? If so, is there a fix, or is it time to consider a new camera?
