7D MarkII Battery Performance

[leichenmuehle]

Hello Guys, exactly one month ago i had bought the new 7D MarkII.
Since this date i shoot ~900 Pictures with it. So in my opinion after 100 shots the battery level is down, and i
have to recharge the battery. This makes me think about it, the outside temperature in our country levels about 0 degree celcius! Has any one the same Problem? Or is it maybe the AF system who leeches out the battery?
Thank you

There were people that had issues early on, but I haven't seen nearly as many complaints. So it is possible you have a poor performing battery.

That said:

Temperature does make a difference.
I found the battery performance got better after a few charge cycles.
GPS matters, I keep mine turned off most of the time.
IS uses power.

I shoot sports and I can shoot several games (800-1100 shots per game) on a set of 2 batteries with no worries.

I have shot 250 pictures outside at -15C and used between 1/3 and 1/2 of the battery, so 100 does not seem right. I have shot 500 pictures outside around freezing and used about 2/3 of a battery....

What I have noticed, but so far it is a feeling, nothing scientific, is that in Live view the camera eats batteries much faster than the 60D did, but in normal use it is close to the same for battery life.

When doing AFMA of several lenses using Reikan Focal, it really goes through batteries fast. Somewhere in the range of 100 shots for a full charge.

So the same battery can last for 500+ shots or less than 100 shots, depending on what I am doing. Obviously, there is some combination of settings that eats batteries like popcorn... Does anyone know for sure what this magic combo of settings is?

I'm having the same pendulum swing with battery performance on the 7D2.
With Canon's two battery grip attached, the range of captures run from as low as 600 (300 per battery) to several times when the number has passed 2000 (1000 per battery). Not much chimping. Image review turned off. Wide variety of lenses from manual focus Olympus primes to full AF, IS, 10-22mm up to 400mm f/2.8 Canon lenses. Temperatures ranging below freezing to mid-50 degrees Fahrenheit. None of these variations consistently add up to better or worse battery life.
The one thing that does seem to matter is shooting duration. If shooting at 7-10 frames per second and going through a lot of frames in a couple of hours, the battery just seems to go and go. If shooting only a couple hundred frames per day over a three day period, it drains rapidly.
I've been used to the 1D series bodies and 5D3 where the power is always on and the camera goes into sleep mode but is always ready for immediate use when needed. With the 7D2, I'm now in the habit of turning the camera off after each use. Removing the battery entirely helps even more but then you lose the battery gauge and capture number per charge.
I'm guessing that these wide spectrum of captures per charge has something to do with the viewfinder potentially drawing a constant charge when batteries are in the body. When batteries are in, the viewfinder is bright and clear as it should be. Batteries out and it goes dark and unusable. The cool and informative screen overlay might be a steady drain---long term/few days---even if the features and warnings are turned off.
Just a thought.
Or my body has a short somewhere. Or I have a bad batch of 4 batteries. Or aliens are occasionally using the 7D2 to transmit messages back to the home planet...which would actually be kinda cool.

With out actually counting shots(approx 800) I had to use 2 batteries shooting in warm weather (65 degrees) shooting on high speed, lots of zooming (70-300 IS) back info screen turned on, as I was making adjustments quite often.
My batteries were fully charged and GPS was off. I'm going out again in two days and will try again. My camera was on pre-order so I'm imagining it was an early model ?? If that makes any difference?? Now I'm really curious!

I have been surprised how good the batteries have been with my 7d2. I'm about 20,000 exposures into this new body, and I've been using a combination of Canon brand batteries that came with the 7d2 (the "n" version, which is supposed to have some nominal amount of extra juice) and my off-brand Wasabi batteries that I have had very good experience with in my former body, the 70d. Interestingly, the Canon batteries have gotten better and better each time I charge them. I'm getting about 1,000-1,200 exposures per battery. I do shoot in bursts, doing wildlife (and 4-year-old human wildlife), and this seems to really up the shutter count per charge. However, my off-brand batteries are doing terribly. I might get 400-600 shots per battery. I do not know why this would be the case, unless those "n" batteries made for the 7d2 have a lot more extra juice than advertised.

I'm not doing chimping, do not have GPS turned on, and generally have a pretty low power profile in my use of the camera, but this isn't a deliberate effort, but rather just how I like to shoot. Oh, and I've been shooting outside in weather that has been roughly between 10 degrees and 30 degrees f.

I hate how much Canon charges for name brand batteries, but I think that's the way to go with this camera.
