Vampire Drain

[Tesla2.0]

It will. In order for it to not drop, you currently have to go and drive. How far? Not sure..I’ve driven 40+ miles after completing a charge and in the few hours after parking, still lost range. I have also charged and driven 185 miles and then parked, didn’t lose range. Sooo somewhere in that ballpark!

So Tesla is daggers by Phantom Brake.
Lucid is now daggers by Phantom Drain.

I would rather have the latter.

But Lucid hasnt even enabled dreamdrive to see if it’s going to have phantom braking or a different issue!

So more daggers may be coming.

I am the owner who bricked their Lucid by going to New York for 2 months. The car was picked up June 16th, it is still in the service center. They replaced the battery on the 14th of July. On Saturday morning it was charged to 455 miles of range. It was unplugged after this and as of now, Tuesday morning, it has 421 miles of range. That is approximately 8% of the charge in 60 hours. If the BMS uses the battery for battery conditioning and not the charger, this fully explains why my battery had 0 range after coming home from a two month trip. Even though it was plugged in. 1. Is this the kind of drain other owners are experiencing? 2. It seems this is not a car you want to park in an airport parking lot for a 3 week vacation.

That is high from what I see. I will see 3-4% of the battery used within a few hours after charging and then <1% overnight Without charging. Lucid needs to have a vacation mode for those who take extended vacations. Set a minimum and a max. if the car reaches the minimum while plugged in, then It will charge to the max. Also a time function where the capharge only occurs, for example from 12-6a.

I would assume that battery percentage is more accurate? I assume the miles is more of an estimate based upon an algorithm. Percentage should be more of a hard number.

My numbers are based on battery %, not miles. I would assume the same thing. Of course battery % depends on a linear curve from 0 to 112 kWh. Not sure what algorithm they use for either. My numbers of kWh added based on battery % is 22% higher than what the car says it consumed since the last charge That is the root of a lot of questions I have for the battery and software people.

Perhaps I'm missing how to see % on the app. All I can see is miles. I am don't have the car with me. In the 25 minutes since I posted the above message, it has gone from 421 to 419 miles.

You can change it under the setting in the app - miles vs percentage. It's under Settings, then Units.

I think phone proximity have something to do with it. I noticed that when I was in the EU for three weeks, the car drained 1% a day. When I’m home, it drains about 4% a day. The key fob was in the same place, so that wasn’t a factor.

It’s hard to have it both ways: You want the car to wake up when you approach it with your phone but you don’t want it to wake up and consume battery power. If only the Lucid had software sophisticated enough to know what I was thinking. I’m sure that’ll be in the next OTA.

It would be nice to have it both ways. Other companies have figured it out. It’s almost certainly a software and battery management issue. It should be fixed in the future.

If it’s not then perhaps Lucid made a deal with the devil to get their range. That battery pack has to stay cool somehow.

Excellent. Thank you. I have never gone into settings! It is now at 92%. So from 100% to 92% in 60 hours. Is this a normal drain? I need some kind of knowledge when speaking with the service rep at Lucid. I don't want to have this situation again.

Actually, all I want is for it to keep it's range when it's plugged in. I have a Tesla Model S #895 from 2012 and that's exactly what it does.

Funny(maybe not so funny) is that there is less drain unplugged than plugged in. Also important to keep the keys away and phones away. Like we calculated in another thread, you can get 0.6% drain a day under ideal conditions (garaged weather less than 80 higher than 60).

BINGO!!!!

I was in EU 28 days, battery drain was 11%, now I’m home, it’s 2~3% per day. Maybe it is phone that causing it. I thought maybe just hot summer or ver 1.2.6. I think maybe I better off start turning off phone Bluetooth and go back to using fob.

How many of you guys having issues with vampire drain are using the mobile key? I'd suggest using the fob exclusively for a week and see the difference.

Yeah, I suspect the mobile key is playing a part in this. I came downstairs the other day to make coffee and all of a sudden I hear whirring coming from the garage. Open the door, the car is unlocked and fans whirring away. It's funny that the stairwell is probably 15 feet from the car and through a wall and yet, the phone seems to unlock the car but when out in public it's next to near impossible to get it to unlock unless you're 1 to 2 feet away.

I'm sure the metal supports/nails in your wall help amplify the signal from your phone to the car.

I just checked my Bluetooth, I’m 40 feet away in backyard. My phone is connected to Lucid. I just turn BT off from now on and observe.

That makes sense to me (engineer) and a fixable software problem. Using a mobile phone an example, if you kept waking it, enabling notifications, and bringing detectable accessories near it, it would drain the living Hell out of it.
