Tesla Model 3 “Phantom Drain” compared to Model S and Model X

Published

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.

Tesla’s retail sales in China climbed to 71,525 vehicles in September, the company’s second-highest monthly total this year, as per data from the China Passenger Car Association (CPCA). 

The result reflects a steady rebound, narrowing Tesla’s year-on-year sales decline to just 0.93%, while showing a 25% jump from August’s weaker numbers. Tesla China’s September numbers are just below the 74,127 units that were sold domestically in March.

Tesla China’s September

Despite the uptick, Tesla China’s retail sales have now logged seven months of year-on-year declines this 2025, managing growth only in March and June, though a good portion of these lost sales was due to the changeover to the new Model Y. The Shanghai Gigafactory, which produces both the Model 3 and Model Y, continues to serve as a dual-purpose hub for domestic and export markets.

In September, Tesla exported 19,287 vehicles from its Shanghai facility, up 19.6% year-on-year but down 25.9% from August, as noted in a CNEV Post report. This is in line with Tesla China’s strategy of prioritizing exports early in each quarter. Including exports, Tesla China’s total wholesale volume reached 90,812 units in September, up 2.82% year-on-year and 9.16% month-on-month.

Model Y still leads

The Tesla Model Y still led the electric vehicle maker’s sales in China with 59,907 units sold wholesale during the month, rising 17.1% from last year, while Model 3 reached 30,905 units, dipping 16.8% year-on-year but up 27% from August. Tesla’s overall market share in China’s NEV segment rose to 5.52%, and its BEV share climbed to 8.66%, modest gains hinting at the company’s resilience in a fiercely competitive market.

Across Q3, Tesla sold 169,294 vehicles in China, down 6.9% year-on-year, marking its second consecutive quarterly decline but a strong 31.4% recovery versus Q2. Year-to-date, Tesla’s retail total stands at 432,704 units, down 5.97% compared to last year.

Elon Musk teases ‘Banish’ feature to pair perfectly with Summon

Tesla has long promised the possibility of completely hands-off parking: arrive, drop off at the entrance, the car parks itself, and the car retrieves you at the end of your visit.

Elon Musk has once again teased the “Banish” feature that could come to Tesla vehicles in the near future. It would be a perfect pairing to the popular Assisted Smart Summon (ASS), which the company launched earlier this year.

Banish has been something Tesla has teased for years. The company has promised the possibility of completely hands-off parking: arrive, drop off at the entrance, the car parks itself, and the car retrieves you at the end of your visit.

Ultimately, even though it is technically a driverless feature, Tesla has not refined its parking portion of the Full Self-Driving (Supervised) suite enough to release Banish to the public.

Tesla recently started performing specified parking tasks at the driver’s discretion. In the FSD (Supervised) v14.1 release, Tesla has added the ability to pick your parking scenario. Drivers can choose a Charger, Parking Lot, Curbside, Street, Driveway, or Parking Garage.

To achieve Banish, Tesla would have to gather enough data with these scenarios to then gain the capability to park after dropping vehicle occupants off.

However, CEO Elon Musk recently hyped Banish to the point of stating Teslas will be capable of it “in the near future.”

His remark came in response to a video where FSD v14.1 drove around a Costco parking lot for twenty minutes looking for a spot:

Summon is a feature that has given Tesla its challenges, but the release of Assisted Smart Summon (ASS) has improved some of its capabilities.

I tested it after receiving v14.1, and it did a great job of taking the correct route and driving safely to my location:

There will likely be some time between now and when Tesla is able to release Banish. As previously noted, Tesla will need to collect enough data from real-world scenarios and obtain a proven track record of being able to handle lots and parking in a variety of environments while supervised.

Tesla faces new blockade in Sweden as IF Metall escalates dispute

The action takes effect October 15 and will remain in place until Tesla signs a collective agreement.

Just over a month after the Swedish Meditation Institute threw in the towel on Tesla and IF Metall’s conflict, the labor union has announced a new industrial action aimed at disrupting the electric vehicle maker’s operations in the country. 

Potential Tesla disruptions

The latest news involves a total work stoppage by Linde Material Handling, one of Sweden’s largest forklift companies, which services industrial clients nationwide. The action takes effect October 15 and will remain in place until Tesla signs a collective agreement, as noted in a Dagens Arbete (DA) report.

The stoppage will halt all forklift-related work Linde performs for Tesla’s local subsidiary, TM Sweden, including maintenance, repair, and service of trucks used across its facilities. Simon Petersson, IF Metall’s contract secretary, shared described the union’s latest effort in a comment to the publication.

“We know that Tesla has trucks in several locations and that they are in need of service, maintenance and repair. We are stopping that now. For Linde, this is not a big deal. They service trucks for a lot of companies and Tesla is a small player in their portfolio,” Petersson noted.

Not a sure strategy

Whether IF Metall’s latest effort will succeed against Tesla remains to be seen, especially since the electric vehicle maker has been pretty firm in its stance that its employees do not need a collective agreement. Still, the IF Metall contract secretary stated that Linde’s strike against Tesla should make it more difficult for the electric vehicle maker to operate its business in Sweden.

“It remains to be seen. But as I have said before, it is about many small streams. This stops everything Linde does for Tesla. So not only with them, but regardless of where the work takes place. So if Tesla has problems with a truck, they will not have it repaired or serviced,” Petersson stated.

Following the decision of the Swedish Meditation Institute to end the negotiations between IF Metall and Tesla early last month, the union noted that it would still try to pressure the EV maker to sign a collective agreement. Since then, the Electricians union, as well as the postmen’s unions Seko and ST have continued to initiate blockades against Tesla Sweden.
