But that's not the case. The camera consumes power just by staying on all the time, so a longer interval, results in longer stand-by time, and consumes power nonetheless. So, 2 hours and 1500-1700 pictures at 4-5 sec interval seems to be the maximum.
FWIW, some time ago I did some detailed testing : Battery Intervalometer

There are a few different shooting conditions documented there, but with the display off I found that shooting time with 60 seconds between shots was about 2.5x longer than the shooting time with 4 seconds between shots.

How about this? https://support.usa.canon.com/kb/index?page=content&id=ART157723
The genuine Canon A/C adapters are very high quality but usually cost about $80 (or more).  You can get cheap Chinese made clones on eBay and other places for $15 or so.  Quality varies a lot - I've had to replace capacitors for example.

Really?

I have done measurements on S110 with set_backlight and set_lcd_display.

Shooting Mode 0.44A
Shooting mode + set_backlight (0) 0,40A
Shooting mode + set_lcd_display (0) 0.38A
Shooting mode + set_backlight (0) + set_lcd_display (0) 0.36A
So, you can save around 20% on S110 with the display.

I could not see much differences on shooting mode (Continuous, single mode).
Yes of course, focus and IS needs energy but I have always switched IS off and focus is locked.
And I never checked switching to Playback Mode between shots.

Yes - really. 

That's the nice part about having actual test data of real shooting.

From my original post :
Quote
There were two test suites -  one set of test was conducted at a 4 sec per shot interval and the other at a 1 minute per shot interval.
Test Suite One
Shot Interval :  4 seconds
Trial    SetupResults
1no optimization3013 shots over 3:02 hours
2backlight off between shots   3302 shots over 3:35 hours
3display off 4572 shots over 5:04 hours
Test Suite Two
Shot Interval :  60 seconds
Trial    SetupResults
1no optimization207 shots over 3:26 hours
2backlight off between shots    253 shots over 4:12 hours
5backlight off between shots, screen off via power save after 10 sec 566 shots over 9:26 hours
3backlight off, idle in playback mode   640 shots over 10:48 hours
4display off 811 shots over 13:30 hours
The camera was an A1200 using AA rechargeable batteries.  Obviously, different cameras might produce significantly different results.

Hmm, focussing..

I noticed that the camera keeps on focussing before taking a picture. That also uses some power. I lost the manual, is it easy to lock focus?

If you are using a script, set_aflock( ) will do it for you. 

Otherwise, use the Canon keyboard to lock it.
