If GearGuard is truly "off" and it's just telematics causing the large drain... give us a way to turn them off. It's one thing to data-mine every bit/byte of data from your customer's vehicle for company use.. but to cost us $$$ to send you that data is just out of line. If it's also due to battery conditioning, there certainly are plenty of times conditioning is not needed. Turn that off too.

For a supposedly "green" vehicle, the Rivian is extremely wasteful...
It's like they shipped the car with debug level set to high. Well, version 1.0 is bound to have opportunities for optimization - hopefully we don't have to wait for the release of a new car to fix this and the optimizations can be done via software/firmware updates and not requiring hardware changes.

I will, again, remind you all that Tesla has not "fixed" this in as long as they have been making cars.

My 2017 i3 has no vampire/sitting battery drain that I can discern. It's gone 5+ days without being used, even in the winter and it's still got the same range it had when I last used it. Also, the phone app works any time I've checked in on the car so it's not like it's dead to the world till I power it on for the next drive. It's still available, sending and receiving data... but in an efficient manner. It seems Chevy (the Bolt), BMW, and some others have figured out how to minimize battery drain when not being used, and others haven't (yet).

I'm not sure what "this" refers to specifially in your reply, but if you mean phantom drain I'd agree it's not fixed. I'm not sure it can be fixed at least with current lithium battery tech, but several companies have made the drain reasonable. My vehicle has been idle for 3 days with sub 40 temps overnight and currently it's lost 1%. At this rate I could leave it for over month before it runs down to zero. Tesla's had years to improve so I'll give Rivian a bit of time to address it.

I don't think people are expecting it to be "fixed". I think they are expecting it to be mitigated. Different people do have different ideas on how much it needs to be mitigated.

My 2016 Model S works well. The first 24 hours I might lose 2-4 miles but after that less than a mile a day. I can go away for 2 weeks and will lose less than 12 miles when it is in my garage. I would expect Rivian to lose more because of the watts per mile but would expect it to be less than 20 miles in 2 weeks with gear guard off.

Yeah I was commenting earlier in this thread or on another that in the two-three weeks after I got my R1T I didn't drive my EV6 once, maybe moved it in and out of the garage. I didn't lose more than 1% of battery in that time. It's not like Kia/Hyundai has been making EVs that long either.

My truck is off at service right now. I was also having an issue with the truck not letting me remote condition occasionally because it thought there was someone in the vehicle. It would make sense that if that's still happening, that the truck wouldn't actually go to sleep based on what's written in the R1T manual.

How do you know if your R1t is "ready" or "off"? Does your app still talk to R1T when it is off?

The opposite makes more sense to me. Larger pack means Rivian should lose less miles if electronics have the same amount of waste in watts. If both Rivian and Mini lose 1 KWh in 24 hours. Mini lose 4-5 miles, Rivian lose 2-2.5 miles.

I stand corrected, that makes sense, not because of the battery size but the consumption.

The Tesla gets around 290 watts per mile, the Rivian probably around 430 watts per mile. If the vehicle sat and consumed 3000 watts, that would be 10.3 miles on the Tesla and 6.9 miles on the Rivian.

That's a good question. Right now if I look at the app, I see this:


Rivian R1T R1S Any tests done on Vampire battery drain? Screenshot_20220428-194839

The truck is at the Rivian service center, I can't say I remember seeing this "Wake Vehicle" thing before. Since sleep is the opposite of wake, I have to believe that it's in sleep right now. Hopefully that means they fixed the issue that was causing it to always be awake. Hopefully it isn't just able to sleep just because my phone isn't 50 feet away anymore. I'll check the battery level again in the morning.

Not long before this, Tesla had a terrible issue with phantom/vampire drain. It was bad enough people were disabling remote access just to prevent extended loss on trips.

It took them a while to get the balance of remote access and software right to where it was that good.

On top of that, they just introduced (or are introducing) a new feature that caches some values on their servers, reducing how often you need to wake up the car. So even they are still working to improve this, to this day.

I don't think they ever had quite as bad of a drain as the current Rivian problem, but I also think the current Rivian problem is about not optimizing the software correctly, and my opinion is that they'll have a software fix within a year at the most.

It raises the question what “sleep“ means if it still can tell the app what SOC is and if it still can scan for your smartphone. Sleeping with one eye open still uses some energy.

Telematics is likely always on. It probably periodically wakes subsystems to check stuff like the voltage level/temperature of the pack/cells. When the truck is "Ready", that means all the subsystems are going to be active and in a state where the vehicle is prepared to drive. I assume this is what happens if you manually wake the vehicle.

I wonder how much energy goes to talking to the mothership. Can you turn off WiFI easily through the settings or you have to delete your network completely?

Wifi has a slider for on/off.
