EOS R draining battery overnight

Hi all, my R is draining battery overnight -30%...gps is off, wifi is off, camera is off! Any ideas? Using original LP-E6N battery.

IIRC, there are two levels of "off" for GPS, one of which turns off the computer that determines the camera's position but leaves on the collection of certain background information that makes that determination go faster when the camera is turned back on. So be sure that you have indeed turned GPS completely off.

Except having the gps function on "disable", is there another setting?

Make sure both Wi-Fi and Bluetooth are disabled, too. If it still drains overnight, try removing the memory card, and see if it still drains the battery. If so, you may want to try a spare battery and/or contact Canon Support.

The option Bob is referring to is "Mode2", but if you have GPS "disabled" or off, then something else is draining your battery.

WiFi or Bluetooth maybe?

Or there are those who never turn their camera's off, and rely on the "low power state" which only requires that you press a control or depress the shutter halfway to "wake" the camera up. I personally do not use this option. When I'm done actively shooting, I turn the camera off.

Likely causes:

You either have something on, are leaving the camera on and a control is getting bumped, or your battery is shot.

All connectivity options are disabled and the camera is turned off from the dial.

What is your battery showing for recharge performance, it is under the battery info heading in the yellow tool tab of the menu section. If it shows OK here, it still doesn't mean that your battery doesn't have excessive self-discharge behavior but if recharge performance is low then it is a pretty good sign that the battery is degraded.

As a test, fully charge the battery then leave it out of the camera for a couple of days before installing it and see how much of the capacity loss is due to self-discharge. As batteries age, not only do they lose capacity but also tend to have increased loss of charge even with no load on them.

Will do. I just put a new battery in the camera and will check tomorrow. Funny thing is that after 150 shots the battery level is around 40%...i am really worried about having a kind of short circuit in the camera 😞

Running the battery down by taking pictures is a very different phenomenon from having the battery drain overnight. If I recall correctly, the R's viewfinder stays alive for a settable period of time after you take a shot. Setting that to a shorter period may lessen the drain on the battery while the camera is in use. It's just a fact of life that mirrorless cameras are battery hogs.

I have this problem on an EOS R but only when a Laowa 100mm 2x macro (auto aperture) is left attached. The battery flattens in a few days to point the camera will not switch on, degrading the battery. I have not sorted whether it is the lens, camera or the way the are communicating which is the problem.

My 2c

- Canon R is very power hungry, 150 photos, with a bit of fiddling around, will do that.

- the top screen can be turned off as well ( when the dial is OFF ) - I decided to keep it on

- if you have a short in the camera, maybe it should also get hot ?

Sir,

It is Laowa 100mm Canon problem NOT your camera problem

I have 100% exactly same issue

I use Laowa 100mm canon on my 5D mk3

It drain a fully charged battery from 100 to 0 in 3 days

( camera is POWER OFF )

Laowa still cannot tell me how to solve this problem..

If you have any update from Laowa USA, please let me know

Thanks!
