EOS R7 battery goes dead while camera is off

paulk — Wed, 25 Oct 2023 13:57:59 GMT

Why does my Canon R7 battery go dead while the camera is turned off? My 70D and my other T series cameras would sit for weeks on end without the battery going dead. Thak in advance for any information you could share.

There are functions in digital cameras that are powered even though it is turned off.

One that I learned on my 7D DSLR is it has an LCD overlay on the focusing screen that provides illuminated focus points and other things in the viewfinder. I discovered this when I noticed that with the battery out of it, the viewfinder dims significantly. The overlay is not clear without battery power.

What is the model number of the battery grip? What is the manufacturer’s name?

I do not recall Canon releasing a battery grip for this camera body. This means the camera body was not designed to use a grip. Using a third party grip on a camera body not designed to use a battery grip can damage the camera. The damage would not be covered by any warranty.

Hi Paul and welcome to the forum:
I find that quite often camera, especially (but limited to) mirrorless ones, will 'leak' some energy over time, which is why Canon recommend removing the battery from the camera when not in use. Are you using genuine Canon batteries in your camera?

Bill: Does the OP have a battery grip? I don't see a reference to one.

Greetings,

He may have wi-fi and/or Bluetooth turned on. That will run the battery down rapidly if left on.

Absolutely, although they should not drain if the camera is turned off (as opposed to simply allowed to sleep),as they indicate.

LOL. No grip. Watching Monday Night Football and posting to the forums. LOL

How fast is it draining?

We’ve wet and rainy weekends all summer. The weekends are my prime time to get out into a park somewhere and grab photos. My R6mkII with a battery grip lost about half of its charge sitting around on rainy weekends. I’m certain that my wireless is disabled.

I mostly use custom shooting modes. I keep the wireless communications disabled. If I want to use wireless communications, then I have to switch away from a custom shooting mode and enable it.

Even still, I have left wireless enabled when the camera is actually switched OFF, and I have not noticed any difference in how fast the battery depletes itself.

Did anybody ask what lens he's using yet?

Should that make any difference, if the camera is turned off?

Re: R7 camera question

I was trying to address that myself. It is not completely clear that the camera is physically turned off as opposed to let it go into power-saving mode. These small distinctions can make a big difference...

The camera was truned off, not just in sleep mode.

Thank you for clarifying that Paul.
FWIW, Canon recommend removing the battery from a camera when it is not being taken out and used. I have had a lot of cameras from at least seven different manufacturers and many of them 'leak' energy over time. In my own personal experience the LP-E6NH batteries from Canon (that are in your R7) tend to lose their charge capacity quite quickly, in or out of camera.
To figure out if it is the battery, can I suggest fully charging the battery and leaving it out of the camera for a while, then putting it back in to see how much charge is left? If the battery charge remains full, it's more likely something to do with the camera, but if it has lost charge then the battery is suspect.

How long is it taking for the camera battery to discharge. I can leave the battery in my 5D Mark IV for weeks and it won't be dead. My older EOS 40D lasts even longer. If I won't be using my camera for a while. I remove the battery from my camera when in storage. Now my 5D Mark IV uses an LCD overlay in the viewfinder instead of a regular focusing screen. Another user @normandel pointed out that their EOS 7D also has an LCD overlay in the viewfinder. Without a battery in the camera the viewfinder darkens by about 2 stops. So these cameras may discharge the battery faster compared to my old EOS 40D which doesn't have this. It also doesn't have any wireless communication.

Yes, it should. I had the same thought. Third party mount adapter and/or lenses.

There were third party mount adapters that would drain the battery even when the camera was turned off. The incompatible gear was creating a problem because users were blaming Canon.

Incompatible third party gear causing was quickly getting out of control. Canon took the extreme step of banning and prohibiting third party gear from using the RF mount on technical grounds and copyright infringement.

Just leaving the lens or mount adapter connected to the camera when it was switched would drain the battery. Remove the mount adapter or lens after you turn off the camera and the problem would go away!

Thanks. I believe the adaptor is a third-party adaptor. I think I'll go back to the camera store that sold it to me and let them know about this. Maybe a discussion will follow.

I'll try this before going back to the camera shop.

Easy way to start. Remove the lens, put a body cap on and insert a freshly charged battery. Check the battery level in the morning.
