1. To avoid the frequent use of flash: If you are not a professional photographer who, then, except in the invisible fingers of the night, normal daytime light intensity for the average digital camera, it is enough.

2. To avoid unnecessary zoom: zoom the camera lens stretched it out a shrink, very power. You can move hyperactive pace, with the "manual zoom" to replace "camera zoom" to save power.

3. Do not let the screen has been lit: If the case of small power, can turn off the LCD screen, with screen viewfinder to adjust the composition, for a digital camera, LCD should be the most power-hungry components, general digital camera, turn off the LCD screen can be used time after the original length of about 3 times.

4. Less shooting and video: minimize the use of continuous video recording function and video function, because the completion of these features built-in cache is to use the body to temporarily save the screen shot, the power consumption a lot.

5. avoid frequent open, shut: Many users know that the display stays lit is power, so in use to save power, the frequent opening and shut down. In fact, frequent open, shut down the wasted electricity consumption than bright display even more, especially for larger diameter lenses, but also require a substantial expansion of the camera, the switch is power. Most digital cameras have auto-shutdown option, this setting should not be set too short, otherwise easily lead to frequent open, shut. Of course, frequent artificial opening, shut down should also be avoided.

6. optical image stabilization not normally open: Optical image stabilization is by driving the lens or image sensor components, offset by the subject image and the relative motion between the sensor achieved. Either way the optical image stabilization, would lead to a small power consumption, especially in some models can be anti-shake mode is set to "always", the power loss caused by such will be more severe. To this end, we are well-lit scenes should be shut down optical image stabilization feature, you must use, should also be less "normally open" mode.
