EOS 80D Battery Issue

markteach — Tue, 08 Nov 2016 13:48:07 GMT

My battery drains within 24 hours, even with On/Off switch turned off. I have tried 2 different batteries and 3 different chargers - same thing. It does seem to last longer if I place it in P mode before turning off.

That's pretty odd. I assume that the batteries have been fully charged, and that they are Canon batteries. Does it drain the batteries without a lens attached to it, also?

Have not tried it without the lens, yet. I will try that next. Thanks!

I believe I fixed the battery issue. I'm thinking the batteries shipped with the new camera from Amazon must have been sitting on a back shelf for a long time. After fully charging and discharging each battery about 8-9 times, they each seem to be holding the charge. At least they've been hanging in there for about 3 days now and counting.................

Thanks again.

That's good news. I hope that they're genuine Canon batteries, and that the camera recognizes them, so that you can track shutter counts on a battery charge. Refer to page 452 of the full Instruction Manual.

Thanks. I'll try that.

3 days is still pretty pitiful.

I have just purchased an 80d, but found that battery arrived in box with body with zero charge, if the battery is left in camera even with camera turned off the battery is dead after 6 days, canon response is to remove battery between uses not so good for picking up and being ready to shoot pictures.

never had this issue with previous 450d and have checked with friends that have 700d and 7d mk1 they can leave battery's in camera and no drain on power when off.

begining to think 80d does not turn off fully by top switch

i will try the recharge of 8-9 times to see that improves thank you

It is true that the on/off switch effectively puts the camera into a kind of "sleep" mode. It doesn't actually cut the power (it's more of a software switch rather than a physical breaker). This would be evidence by the fact that the camera can perform a cleaning cycle even after the swtich is thrown.

I don't believe the 80D has a built-in GPS but GPS-enabled models have the ability to leave the GPS running even if the power is off.

Do you have any 3rd party accessories attached to the camera? For example... a 3rd party lens or a 3rd party battery grip, etc.?

Thanks for the current replies to my battery issue. After working with it for awhile, I believe I figured out the problem. Over the course of a few weeks, I managed to completely drain and recharge the battery numerous times. This seems to have fixed a "battery memory" problem it must have had probably sitting on a shelf for too long. I am now getting a very decent amount of time on my battery and am working on doing the same with the other battery. So far, the second battery seems to also be coming along nicely. I'm confident, for me, that this is solving the problem. Thanks for all of the concerns and help.

That kind of "memory" issue was common in older nickel-cadmium (NiCad) batteries, but supposedly not in more modern nickel-metal-hydride (NiMH) or lithium batteries. It certainly shouldn't happen with the battery of an 80D. Are the batteries you're using genuine Canon batteries or those of a third-party manufacturer? If they're actually NiCads, that might explain the behavior you're seeing.

One is a Canon battery, the other is a cheap "Focus" battery that came with the "package" from Amazon. They are both holding up nicely, now, though.

I would not risk a thousand dollar camera with cheap, "no name" batteries. Beware of counterfeit Canon batteries, too.

That's good; and if you're lucky, that may be all you see of the problem. But if they're NiCad batteries, they may revert to their old ways if you don't run them down completely before each charging. If that requirement were to prove too annoying, you might have to buy better batteries.

The Canon battery was boxed and sealed with the camera. I'm pretty sure it's legit. I will probably just use that one since my shooting times aren't excessive.

That's a good sign. If the camera can read the battery information, that's even better.

EOS 80D Auto Shutter Closure With Bulb / Intervalometer

Escalante101 — Thu, 15 Jun 2017 05:01:29 GMT

I tried to send an e-mail to Canon, and when I clicked on "Submit", it failed to connect. So, I am posting my inquiry here. This message does not concern an "issue" per se, rather a technical / operational inquiry. I am planning on making my initial forays into astrophotography / light painting and have a couple of questions on the Bulb setting / Intervalometer. I also invested in a Neewer digital timer / remote. If I use the Bulb setting on the and use either the RC-6 or RS-60-E3 remote cable, and I set the Bulb timer, let's say for 25 seconds or so. When I press the button on either of these devices, it will open the shutter. My question is whether when the 25-second time expires, will the camera automatically close the shutter on its own - or - do I have to do that manually. I did order a stopwatch, by the way, in the event the camera will not close the shutter automatically after the expiration of the 25-second time period. Likewise, if I would use the built-in intervalometer and set it for only one photograph and a 25-second exposure length, would the camera shutter automatically close after the 25-second time period passes, or does that have to be done manually? I would really like to be able to run into the picture and light certain areas with a flashlight for light painting purposes, and it would be very helpful to know whether the camera is going to automatically close the shutter on its own using the Bulb setting, or whether I would have to use my stopwatch and run back to the camera to press the button on the remote within my chosen exposure time length. I hope this makes some kind of sense. I was unable to make this determination through reading the Manual or online research.

We have one or two people in the group who are astrophotography experts, so I won't try to answer the bulk of your questions. But I would point out that virtually every cell phone in use in the world today incorporates a stopwatch.
