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.

Elon Musk confirms Grok 4 launch on July 9 with livestream event

The rollout will be accompanied by a livestream at 8 p.m. Pacific Time.

Elon Musk has officially confirmed that Grok 4, the latest version of xAI’s large language model, will launch on July 9. The rollout will be accompanied by a livestream at 8 p.m. Pacific Time, hosted on xAI’s official account on X.

xAI goes straight to Grok 4

Back in May, leaks indicated that xAI was getting ready to ship Grok 3.5. Considering Musk’s recent comments, however, it appears that the artificial intelligence startup would be focusing on the large language model’s fourth iteration instead. As noted in a Financial Express report, users on X have sighted references to Grok 4 in the lead up to the update’s launch, such as “grok-4-prod-mimic” and “Grok 4 Code.”

Musk’s Grok 4 announcement comes as AI competition intensifies between major players including OpenAI, Google, and xAI. With Musk’s Colossus supercomputer fully operational in Memphis, xAI appears to be accelerating its AI product roadmap.

Musk pushes Grok toward political neutrality

Grok 4’s launch also follows a recent controversy involving political bias, as noted in a CNN report. Last week, Grok responded to a user on X stating that political violence in the U.S. since 2016 had come more from the political right than the left. The chatbot noted in a later reply that its answer was based on information from sources like Reuters, the Journal of Democracy, and University of Maryland studies. 

Musk stated that Grok’s response was a “major fail.” “Major fail, as this is objectively false. Grok is parroting legacy media. Working on it,” he wrote in a post on X. By the end of June, Musk noted that he was “grinding all night with the xAI team” and that they were making “good progress.” He also stated that the model “Will be called Grok 4. Release just after July 4th. Needs one more big run for a specialized coding model.”

Tesla has officially launched the first several Supercharging posts at a massive station in California, notably including solar canopies and grid-scale batteries to offer completely renewable charging.

Last week, Tesla announced on X that it opened the first 84 Supercharger stalls of a planned 168-stall station in Lost Hills, California. Additionally, the massive Supercharger project features 11MW of solar canopies and 10 Megapack batteries for off-grid charging powered entirely by solar energy.

Tesla completed the first phase of the project just days ahead of the busy Fourth of July holiday weekend, adding that initial construction took just eight months. In addition to the remaining charging stalls, Tesla says it’s building a set of lounge areas, renderings of which can be seen below alongside current photos of the site.

Notably, the site also includes V4 charging posts for the company’s latest available charging speeds, and it’s located near the busy junction between I-5 and Highway 46 in Kern County.

“Thank you [Kern County] and [PG&E] for collaboration and approvals,” Tesla wrote in a follow-up post.

Testing at the LA Diner, plus Musk update on potential Tesla solar Gigafactory

The huge Tesla Supercharger station completed phase one of construction fairly quickly, especially given how long Tesla has been working on its unique Los Angeles diner, drive-in, and Supercharger location. Still, the company was seen performing some testing at the nearly-completed charging station earlier this month, and will reportedly be holding a job fair.

Elon Musk also responded on Monday morning to a post on X, suggesting that Tesla is “thinking about” building a U.S.-based solar Gigafactory in order to help support increased power needs with AI growth, and to bolster domestic solar production.

The driver of a Tesla Model Y survived and walked away from a harrowing accident on Monday in California, only sustaining minor injuries despite the vehicle being impaled by a guardrail.

On Monday morning around 4:34 a.m., the Los Banos division of the California Highway Patrol (CHP) responded to the accident on I-5 near Panoche Road, involving a 23-year-old in a Tesla Model Y. According to a post on social media, the driver veered off the road for unknown reasons in the northbound lane, before crashing directly into the guardrail and impaling the vehicle.

You can read the full message and photos from Los Banos CHP below, as were shared in a Facebook post on Monday afternoon.

This morning a Tesla model y was traveling in the #1 northbound lane of I-5 north of Panoche Rd. For unknown reasons driver allowed V-1 to veer off the roadway, travel through a dirt center divide, and crashed into the fixed metal guardrail. Lucky for the driver he only sustained minor injuries and was able to walk away. Driving a vehicle requires 100% attention to the road. Avoid distractions and focus on driving.

In a statement to SFGate, CHP officer Myles Anderson said that the driver only sustained minor injuries, while no arrests are made and drugs and alcohol are not suspected to have been involved. The report also notes that Tesla’s “cruise control and lane assistance features” were activated, according to Anderson. However, it’s not entirely clear if this is referring to Supervised Full Self-Driving (FSD), or to the cruise control and lane assist features baked into Autopilot.

At the time of writing, CHP has not yet responded to Teslarati’s request for clarification and additional details on the matter.
