I have no idea how you are getting that many frames. I'm getting about 1/4 of that. You must have gotten a "special" battery.

I wonder too. 1-2K generally get me to 50% on the IV. But, based on my experience with the III in various shooting situations, it depends a lot on a number of variables. For example, if I'm shooting sports action, I review images much less frequently and with the III found I could easily do a 2000 frame game and still be above 70%. The IV definitely drains the battery faster in similar situations, but if it's all JPEGs then it seems to be a lot more miserly. For example when I initially did some lens tests with it, I only shot in JPEG and after 1300 frames the battery was down maybe only 10-15%. (But I believe Nill shoots in RAW). From what I remember in the IV whitepaper, one of the power consumption increases was from the higher speed UDMA interface. This makes sense because pushing all those huge RAW files through much faster requires more power... and I noticed that even a few relatively short video sessions, perhaps a few minutes each spaced relatively closely together, heats up the camera a lot.
Well I hardly ever chimp but I do have the camera set on automatic 2-sec review. I should probably turn that off. And I have the Set button set to turn on Live View, so it gets turned on accidentally occasionally. And I have IS turned on about half the time.
I'm shooting RAW only, writing to a fast Gmonster 533x 32GB card about 60% of the time, to slower non-UDMA 8GB Ridata 150x cards or Extreme II SD cards the rest of the time. (I shoot the girls' games on the slower cards, the boys' on the Gmonster.)
Maybe it's all the processing power required to churn those RAW files into jpg's that eating y'all's batteries? (Just kidding... I know there's a jpg embedded in the RAW file.)

I still don't get it. I only very rarely chimp. I have LCD review turned off, and I have the camera set to power down after only one minute. I suppose I could be getting some significant drain when I'm shooting a still wildlife subject and trying to patiently wait for it to move. During that time, I'm often focusing on the subject and while I'm waiting for something to happen, and I'd guess that, especially with IS, I'm using the battery more than if I was just shooting. In any case, I rarely enough shots in a day to drain more than a fraction of what I'm getting from a full charge.

I suspect that's it. You're using a lot of battery power not shooting. I'm pretty much shooting. (And my camera is set to power off after 8 minutes... so it rarely powers off. Maybe you use a lot of power pressing on the gas when you crank it back up...)
I have it on about half the time, for no good reason other than for when I switch to Av mode for dark sideline candids, and the shutter drops down pretty low.

Good one Nill. I have had my 1d4 for close to a month, at just over 10k with 3 battery charges; set to 2 sec review. I chimp like a monkey and have done probably 45 min of vids; which I bet eats battery power.
Does anyone have experience with how long you can do vids on one battery charge?
I shot a track meet today, covering one team that has read uniforms. I shot them during bright sun and during night conditions.....I have burst after burst of in focus shots like this.
Anyone using AF right-left expansion for moving subjects? I've been using single point no expansion for 1D bodies for about four years...seemed to work the best for sports. But this option seems new?

It's not new, Mark III has it...
I use this option a lot when shooting in portrait position for single moving subject in low light condition,,,,

I used III-4-1 and III-8-1 (left/right point expansion) for the skier shots I posted earlier. It worked pretty well, 1200 shots over 2 days and I had very few frames where AF jumped.

I set the custom function to start IS with the AF-stop buttons (lenses like the 400 2.8 IS). I find this very useful for situations where I want IS, like sideline action. It's a lot easier than finding the IS on/off switch on the side of the lens.
