Some users want to know what camera features consume the most energy and how you can squeeze more life time out of your digital camera battery.
Generally speaking,The biggest energy consumers in a digital camera are the LCD screen and the motors that move the mechanical components of the camera such as the lenses when focusing or zooming. The other big energy consumers are the motors. Digital cameras have motors the move the lenses either to change the zoom or to focus. Motors consume relatively a lot of energy when moving the digital camera optical components. And finally the flash is a big energy consumer too. Shooting photos using the flash consumes more energy that shooting photos without flash.
So some skillful photographer have a few simple guidelines which can significantly improve power consumption and make their Canon digital camera batteries life last longer.
Turn off the LCD and use the viewfinder;
Minimize photo previewing;
Do not use continuous focus when not necessary;
Carry another battery; Two batteries have twice the energy of one.
Recharge whenever you can;
Plan for battery consumption.
