Tesla Model 3 “Phantom Drain” compared to Model S and Model X
Tesla Model 3 currently leads the pack in terms of having the highest parasitic battery drain, or better known as “Phantom Drain”, over Tesla’s more mature Model S and Model X.
Phantom Drain represents the amount of charge an electric vehicle loses when it is not being driven or operated by a person, similar to how smartphones lose battery power while in standby mode. In the case of Tesla vehicles, the battery discharges while the car is not being driven in order to provide power to its onboard electronics and auxiliary functions, such as the battery’s thermal management system. According to the Model 3 Owners Guide, the vehicle, on average, should discharge at a rate of around 1% per day, similar to Tesla’s quotes for the Model S and Model X’s battery drain levels.
However, looking at data collected through TezLab, a popular app among the Tesla owners community that tracks vehicle power usage, efficiency, and other statistics, Ben Sullins of the Teslanomics YouTube channel was able to see a significantly larger discharge rate from the Model 3. Ben was also able to compare the differences in vampire drain between the 3,855 Model S, 1,281 Model X, and 362 Model 3 being sampled.
Looking at the distribution of Phantom Drain between the Model S, Model 3 and Model X, it could be seen that around 60% of TezLab’s users experienced drain levels similar to Tesla’s quoted levels, which are on the 1-2% range per day. However, the differences between battery drain of the Model 3 and the Model S and X become more prominent over time. It’s worth noting that any parasitic losses as a result of TezLab connecting to the vehicle on a recurring basis may also be accounted for in the results being reported.

As noted by Ben, the Model 3’s Phantom Drain levels exhibited volatility sometime during the November 2017 to January 2018 period. Ben’s recent real-world range test using his RWD Long Range Model 3 on an LA to Las Vegas route showed an even more drastic level of Phantom Drain, with his car losing almost 20 miles of range while he and his companion ate lunch. That’s a loss of more than 6% from the Model 3’s rated 310-mile range in the span of an hour.
The drain levels of Model 3 owners using the TezLab app has started becoming more normalized, suggesting that the longer the vehicles are on the road, and as Tesla pushed firmware updates to its Model 3 fleet, the more consistent the cars’ drain levels became. Back in 2015, we covered a Model S that lost an average of 2.3% rated range per day while the vehicle was left in 16-degree Fahrenheit (-9 C) weather.
Overall, Tezlab’s data shows that the Model 3 is becoming more consistent as the maturity of the vehicle’s software is improving. Other features like its battery thermal management systems and its auxiliary functions are improving over time as well. These improvements are a trademark of Tesla, which is known as one of the only carmakers whose vehicles get better after they roll off the showrooms.

Verizon, AT&T and T-Mobile are trying to shut Starlink out before FCC vote
AT&T, Verizon and T-Mobile want 290 MHz cut from an FCC satellite plan before Thursday.
AT&T, Verizon and T-Mobile are asking the Federal Communications Commission to pull nearly 300 MHz of spectrum out of a proposal that would let satellite companies like SpaceX offer cell service directly to ordinary phones. The request lands one day before the agency votes on it.
The FCC will vote Thursday, October 29, on a notice of proposed rulemaking that would make an additional 482 MHz available for direct to device service, expanding the number of eligible bands from five to 13, according to the FCC fact sheet. It would also scrap the rule requiring a satellite operator to lease spectrum from carriers, replacing it with a certification that the operator has coexistence agreements in place or holds the terrestrial license itself.
That second path matters for SpaceX. As Teslarati reported earlier this month, SpaceX agreed to buy Grain Management’s nationwide 800 MHz portfolio to turn Starlink Mobile into a full US carrier, adding to the spectrum it already bought from EchoStar.
The carriers want two bands removed, 2.5 GHz and 3.45 GHz, which make up 290 MHz of the 482 MHz on the table. Through industry group CTIA, they argued that about 300 million users depend on those bands and that satellite operations in them are not technically feasible. T-Mobile, which calls 2.5 GHz the foundation of its Ultra Capacity 5G network, said in its own filing that satellite interference could wipe out up to 96% of a cell site’s uplink coverage area and cut uplink speeds by 88% to 99%.
Executives from all three carriers met with FCC staff on October 20, and T-Mobile CEO Srini Gopalan met separately with FCC Chairman Brendan Carr. T-Mobile’s role stands out because it is still SpaceX’s US launch partner for Starlink Mobile. The three carriers have also teamed up on their own satellite joint venture to pool spectrum, a move widely seen as a response to Starlink.
SpaceX is asking for the opposite. In an October 23 filing after meetings with FCC staff and commissioners’ offices, the company asked regulators to add the 902 to 928 MHz band to the proposal. “Doing so now saves time later,” SpaceX wrote. The company also asked the FCC to modernize interference rules and align satellite deployment requirements with those for terrestrial cell networks, saying the goal is to let satellite and ground networks work together so Americans stay connected wherever they are.
The carriers have not been shy about how they view SpaceX as a competitor. On Verizon’s third quarter earnings call Monday, its chief executive said Starlink Mobile “just can’t compete with a terrestrial network” and estimated SpaceX would need four to six years and $300 billion to $500 billion to build a full US carrier network.
Thursday’s vote will not settle which bands survive. Adopting the notice opens a public comment period, with final rules to come later in the proceeding. The FCC already considered and rejected 2.5 GHz for satellite coverage once, in 2024. SpaceX also is not the only satellite player watching: the FCC approved Amazon’s $11.6 billion acquisition of Globalstar on October 27, giving its planned direct to device fleet its own mobile satellite spectrum.

Tesla Semi catches fire in California: what we know
A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.
🚨 A Tesla Semi reportedly caught fire, with California Highway Patrol confirming. The Semi was on I-880 SB
An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s ‘Emergency Drive Away’ function gets its first use in the real world
Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.
