About: Camera Power Consumption   Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

A. Some people measured the battery consumption rate and found that using the CHDK does not affect battery consumption (either not at all, or just minimally). It makes no difference whether the live histogram etc. is activated or not, because the CPU of the camera always works (looking for keyboard presses in the loop). Btw, histogram is calculated even it is not displayed. But, with CHDK the user usually increases the time when shoot button is half-pressed. Because he is looking at the histogram, zebra, etc. Not just at the green/yellow rectangle. Boot: 200 mA Play mode : 170 mA Zooming: 600 mA

Because he is looking at the histogram, zebra, etc. Not just at the green/yellow rectangle. Here are some measured power consumption rates. The absolute numbers may not be totally accurate. But they should give you an idea about which camera model consumes how much power. Additional power consumption when using the CHDK: none Additional power consumption when using the CHDK: +20 mA Boot: 200 mA Play mode : 170 mA RAW Averaging in File Manager: 240 mA (with 270 mA and 210 mA bursts). Switching into record mode: 780 mA Record mode: 500 mA Zooming: 600 mA Record mode (standby): 70 mA Preparing to go into "half-pressed shutter" mode: 1000 mA Half-pressed shutter: 650 mA Capturing (64 seconds disposition): 540 mA Capture with flashlight: 780 mA Saving RAW file: 340 mA
