I just shot over 800 pictures with 3/4 battery remaining. I put the camera away for the evening the next day the battery was almost dead. Wifi and GPS are both off. Something causes drain when the camera is off.
Do you have a grip attached...specifically aftermarket? That is the only thing I've had drain batteries fast. There was someone reporting the 1.4TC left attached without lens was draining the battery overnight also....

My battery has been fine so far and much closer in usage to my 6D than my 7D mk II, which does drain the battery quickly. Are you sure your GPS mode is set to disable?
My 5D4 drains the battery quickly. 500-1000 shots on one battery. 5D3 would give me 2000 shots in the same conditions and the same lens. Now I always have a spare battery with me. I tried a 5Dsr and notice the same thing. GPS and wifi are both off, auto sleep mode for 2 min and default screen settings.
My 5D IV has been sitting on my desk with the GPS on since I first posted to this thread a week ago - the battery still shows 70% charge (plus I've taken 45 shots with the camera during that time).

Of more concern to me is how long it takes to recharge the batteries - about three hours each.

Sounds like there's something wrong with your charger - my LP-E6N batteries never take more than an hour to recharge (and usually less than that if they aren't completely dead).
Thanks for the feedback.
The 5D4 manual says 2hr30min for a full charge from completely exhausted, but it can take up to 4hrs in low temperatures (less than 10 deg C or 50 deg F). Perhaps the new charger works slowly so that nothing catches fire My 5D4 charger is an LC-E6E, model number DS510102, and it's the only one I have except for the incompatible 1D4 dual-battery charger. My batteries are genuine Canon, or at least genuine enough to make the camera think they're genuine.
The impact of GPS on battery life will likely be greater when the GPS position update interval is shorter. The 5D4 allows that interval to be as short as 1 second up to as long as 5 minutes. I'm unsure whether the camera tries for longer to get a fix when satellite reception is poor, or just records whatever it gets on the first attempt.
There's plenty of scope to account for differences in reported impact on battery life.

All the newer Canon bodies have worse battery life than the last generation. That started with the 7D2, then the 5DSR, now the 5D4. And even the 1DX2 is way worse than the 1DX.
I don't know what Canon is smoking, you'd think we could get improvements in battery life over time and not worse every generation.
Double, triple, quadruple the cpu power, same size battery.
Come ON, canon, there's NO excuse not to advance battery tech, just because the rest of the world can't hack it!
If a new camera has more pixels, features, etc, it's probably going to use more battery power.
I doubt there's been any major breakthroughs in li ion battery technology lately, so short of a bigger battery, with more chemistry, you'd probably get shorter battery life.

Yeah, like the Samsung Note 7.
The question is how much more power can be stored safely in a given form factor.

Its just sort of sad that an extra 2MPs and 2FPS would cause the battery life on the 1DX2 vs the 1DX to be noticeably worse. I don't use any other fancy features or in camera jpeg functions. At least in computers they are improving power efficiencies year to year to give more features with the same battery life. You'd think Canon could go that same way with the processors they use. I'm not asking for more battery life, I just want the type of life I was used to with the 5D2, 5D3,7D,1D4 and 1DX.
IIRC Roger C mentioned that there some extra space in the 5D IV.
I suspect that Canon is trying to hold the line of battery size and maintain oinly a few varieties, but that time may pass. OTOH S*ny has some newer processors that are pushing crazy MP/sec. for the battery size in the MILC.

Not that familiar with 1DX series, was thinking the MP difference was bigger. I wouldn't think 2 MP would do much
The op might get something like this to test usb current and voltage. I would think it would have negative and positive readings, but not sure. Just got mine last week.
Have you guys checked the battery (open circuit) voltage coming off a "full" charge from the charger? If it's not 4.2V, or close, something is likely wrong with the charger, or the battery.
I have used the 5D4 quite a bit now, and the battery life seems the same to me as the 5D3, and plenty for my needs. I have had the GPS on at a low update rate, and the WiFi off. I also have a lot of shooting with the 1DX2, and see good battery life with it too, similar to the 1DX.
You for sure need to check if it is the CamRanger. I could imagine that is a significant factor, but have not even used my 5D4 with my CamRanger yet. Also, any given battery, new or used, Canon or not, can be bad to some degree. Get a brand new Canon battery, and see if that helps. There is even a small chance that your charger is defective, so if you can access another Canon charger to try, that would be good too.

It's been a while but I recall measurements of 8.3V from the LP-E6. There were two series cells.

Sorry you're right, two cells so normally 8.4V (or close) when fully charged.
Another note, we shouldn't necessarily accept that battery life should or will get shorter with each generation due to the demands or processing power required. Sure batteries haven't advanced much in terms of capacity per unit size in the past ten years, but microcontrollers can do more with less power, huge advances have been made in the past ten years in this respect. The same goes for a lot of the other periheral technologies that go into the camera like the rear LCD / touchscreen, sensor, etc.
One other thought, if you are using SD cards, I know there's been some that don't handle low power / sleep mode, if your battery is being drained when the camera is doing nothing, or even "switched off", that might be the culprit.
