7D mark ii batteries going dead over night: My 7D Mark ii is going through batteries like a knife through hot butter. The older 7D could be left on for days/weeks and never run down...

My 7D Mark ii is going through batteries like a knife through hot butter. The older 7D could be left on for days/weeks and never run down completely. But the battery in my Mark ii will often be dead over night. I've tried the newer battery designed for this camera, as well as older 7D batteries. Same thing.

Are others having this problem?

I purchased an extra canon battery when I ordered the camera. No problems with either of mine. I leave one in camera all the time.

For the amount of photo's I have taken, I also feel that there must be a heavy drain on the battery. After approx. 20 photo's, and having left the battery in the camera for a few days it was down to 48%.

Also shooting at 1/1000 of a second of a moving bird I found the results are not as good as I would expect. May just be my camera or me but I'm not happy with the results I have been getting. They are not sharp, and appear fuzzy.

Do you have GPS turned on? I'm hearing that is a battery drainer.
I have mine off, but still agree I don't think the life of these new batteries are anything spectacular.

Hi gym
Have you contacted Canons service department it may be as a simple fix or an update needed to solve your situation!

Do you mean *not* as good as you would expect?

Try bumping up the sharpness in Picture Style a notch or two.

I noticed that when the GPS is turned on, even though the camera is turned off, the GPS symbol is still blinking on the LCD.

I was shooting yesterday with GPS on, and I noticed my battery was draining fast. Swappped batteries, turned off the GPS and battery life was much better.

Yes, "not" and I have added it via edit to my remarks. I will start changing the default settings to see if there is an improvement.

If you have GPS activated it may drain battery, just guessing.

I was talking with a Canon rep this weekend and he said it is a very different camera and you have to go in and pick styles of shooting and you can pin it to a custom place but it seemed there were more settings to play with before taking a photo for sharpness and contrast etc. I would suggest talking with Canon and get a little lesson on settings to get sharper photos etc.

My 6D did the same thing one night. Camera was off but I had left the GPS turned on and the battery was dead in the morning. Since I rarely use the GPS I had never had the problem before. Turned off the GPS and no more problem.

It is most probably your GPS. The camera has the capability of checking your coordinates automatically at intervals from once per second up to once per 5 minutes. If you want your GPS on, obviously the more frequently it updates your coordinates the faster the battery will run down. Th change the settings, go to GPS settings, select "setup" and then go to "position update timing". If you just want to get GPS coordinates for your pictures, then you are probably fine setting the update to every 5 minutes. But the camera has the ability to track where you have been without having even taken a photo. I guess that could have its uses, like if you wanted to retrace your steps on a hike or even a road trip. It will burn through batteries faster, but if you want that kind of tracking it will be worthwhile to carry extras and make sure you keep them recharged.

it is one battery eater and yes I have the GPS turned off but my batteries do not drain out over night.

I am beginning to think that I am going to have to purchase the battery grip. I had been holding out for a third party, but I am unsure how soon they will be available.

I started another thread explaining the reason for the battery drain. It's because I had the Tamron 24-70 on the camera as my regular lens. there are reports that this lens may drain the battery and may need to be sent back to the factory for a fix. If I leave another lens on the camera over night, I do NOT have the problem at all.
