Any tests done on Vampire battery drain?

[Craigins]

The vehicle is still frequently drifting in and out of sleep.

What else would you expect by constantly querying the truck?

I wouldn't expect that sleep pattern. It is too regular and it clearly is sleeping for a large proportion of the time it is being queried. I would expect to see no sleep at all, if regular querying had an effect on it.

What I'm instead seeing is periods of 20-40 minutes of sleep, then about 10 minutes "ready". In 2022.27, I saw the same pattern, but with longer periods of sleep (40-60 minutes) and much longer ready periods of 25-40 minutes.

Even stranger is the occasional "standby". No idea what this means compared to "ready" or "sleep", or why it sometimes happens 2-3 times a night, and other nights, not at all.

Charged the R1T to seventy percent late afternoon on August 29th. It has sat in the garage with gear guard off since then. It is now at fifty-six percent. The only question now is whether Rivian will get me a permanent tag before the battery goes to zero. (My ninety day temporary tag expired on the 29th.)

Your in WA. Expired under 30 days is like a $150-190 ticket. Just drive it; nobody checks nor cares. And 90% chance you could talk your way out of it.

Another live data point. 16 hours overnight and 1 All Purpose mile lost (no change in SoC). That extrapolates to 0.5% per 24 hours.

By the end of the year everyone will laugh about this thread over beers.

My VIN is in 9000 range and don't get anywhere near this good. Gear Guard off. Temps are moderate right now in the 70s. Current software. Lost about 2.5% per day to vampires.

It's weird how inconsistent the drain is from vehicle to vehicle. I don't have the latest update, yet, but I can park my truck overnight and the range estimate is usually the same. Sometimes it'll be 1 mile less. If I didn't read so many threads where people are having real problems, I wouldn't think drain was an issue, based on my truck.

It depends on the day/conditions. I can experience anthing from 0.5% to 2%.

Its an over-active BMS system trying to keep optimal temps I guess....they need to widen the temp range before heating/cooling kicks in. My guess...

Here's the latest under 2022.31, Camp Mode's "Power Off" option for a full day. No appreciable change compared to 2022.27. I'm still losing 6mi/day.

So Camp Mode Off isn't going to change much/anything in a scenario of just letting the truck sit without interacting with it. It's not a mode that makes it sleep more. It's a setting so that when camping, if you are constantly in and out of the vehicle, it won't fire up things like climate, lights and infotainment, which uses up a little energy. That's it. Leaving the truck alone overnight is the same with and without the setting if you're not opening the doors.

The next evolution is a deep hibernation setting, which they are working on for release by the end of the year. That would presumably be the end game for all of this.

They've already done that to some degree, as evidenced by the fact that it no longer consumes any power for cabin/battery conditioning while charging at lower rates, and is reduced at higher rates.

Can confirm now that this makes no appreciable difference. I turned off the polling during the empty section here, and drew a light white line over it. You can see the slope is largely unchanged.

This is something of a surprise! If nothing is querying the truck, why is it still keeping the computers online that could quickly answer such a query?

Well, even after the latest update…still using 1% in 24 hrs. Guess we’ll see what the next update brings. Although 1% isn’t terrible.

I doubt its querying the truck. The truck is probably metering to the cloud. You are querying the cloud.

I could be wrong.

With Teslas, they basically don't report to Tesla servers until there is a client requesting it, in which case the vehicle will wake up and answer the request. This is why reporting services like TeslaFi do a complicated dance to ensure they don't wake up the vehicle unnecessarily.

In contrast, I think your assertion is right. It could be that the truck is delivering metrics to Rivian, servers whether or any client is asking for them. It makes sense to do in the first few months of delivery to keep a close eye on the fleet, but - if true - it should be turned off by now to help with vampire drain.

There is a big range of vampire drain reported here. Even with GG off and PAAK off at home, some people lose nearly 0 miles overnight and others lose several.

It would be nice if people would post which software version/update they currently have. That would make it easier to compare apples to apples. This could account for the differences.

If people confirm all variables in their posts (GG, PAAK, software version) it will be easier to compare vampire drain

If there continues to be a significant variation and vampire drain from vehicle to vehicle despite all the above variables being accounted for, then perhaps some people just have batteries that can't hold a charge well. No amount of software updates can fix that.

We simply don't know yet because most reports don't contain enough I do to draw meaningful conclusions. There is likely some variable that explains why some people are having a lot of drain and others are reporting stable charges over time.

A Tx of cell modem alone every couple hours isn't that bad if it has to wake up to perform other work. GPS trackers run on tiny smaller than cell phone batteries with hourly reports for many days.

I suspect the wakeup occurs for "turn on the AC". I'm just not sure on battery status. On my leaf it pulls from the cloud, but will ask the car if the cloud data is over x minutes old (unless you manually hit the refresh button).

I guess you'd have to try with the truck out of cell phone range in a parking garage or something
