My Samsung DigiMax 210 SE camera is sucking the power out of my batteries in like 2 minutes when I have the LCD on.... I'm thinking on buying rechargeables and using a charger. How long is your's camera's battery life while you use the LCD?

I have a Sony DSC-F505, and when I have my LCD backlight on the battery lasts like 70-75 minutes. With the backlight off about 100 minutes.
