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.

Tesla unveiled the Model Y RWD 110 for Singapore’s Category A certificate of entitlement (COE) rules. This custom SUV tweaks the updated Model Y, which was launched in Singapore in January.
Tesla tuned the Model 3 RWD 110 for Singapore before, and that customized version’s success spurred this Model Y adaptation. The Model Y RWD 110 runs at 110kW, down from 255kW in the standard RWD. It qualifies for Singapore’s Category A COE, unlike the Model Y 255kW version, which sits in Category B.
Category A COEs are for mass-market cars. They score lower premiums than Category B COEs. BMW and Mercedes-Benz register vehicles as Category A COEs in Singapore as well.
In Singapore, buyers need to pay the COE to register a car. The latest tender showed an SGD 22,388 gap between Category A and B premiums.
The Model Y RWD 110’s road tax is significantly reduced from SGD 3,478 to SGD 1,562 yearly. The Strait Times calculated that the cheaper Model Y in Singapore would save SGD 19,160 over a 10-year COE.
The Model Y RWD 110 matches the 255kW version otherwise. The more affordable Model Y’s battery size holds steady. Its energy use, equipment, and design stay the same.
Tesla prices the Model Y RWD 110 at SGD 103,476 before COE. The Model Y RWD 110 costs SGD 3,026 less than the 255kW version, excluding COE costs. It uses a 62.5kWh lithium iron phosphate battery.
Tesla has released cheaper versions of its cars before. For instance, it rolled out a more affordable Model 3 in Mexico last year. The cheaper Tesla Model 3 in Mexico did not use the same materials and had different features to reduce costs.
Tesla might consider releasing custom, cheaper versions of its vehicles in other countries. Industry sources in China hint at a “lower-priced Model Y” for the Chinese auto market, which keeps the Juniper’s battery and chassis

Tesla US Gigafactories Shielded from Trump’s 25% Tariffs
Tesla stocks climbed after U.S. President Donald Trump announced tariffs on imported cars and auto parts, standing out in the United States auto industry.
Automaker stocks tanked after President Trump slapped 25% tariffs on foreign autos and parts. Tesla slightly dodged the tariff blow thanks to local production. Its gigafactories in China and Germany don’t supply Tesla vehicles to the United States market. The company builds all U.S.-sold EVs in Fremont, California, or at Giga Austin in Texas.
TD Cowen analyst Itay Michaeli sees the American EV automaker as a winner in Trump’s tariffs games.
“Tesla [is] a relative beneficiary given [its] 100% U.S. production footprint, substantial U.S. sourcing, and with Model Y competing in a midsize crossover segment where close to ~50% of vehicles could be subject to tariffs,” Michaeli wrote on Thursday.
Rivian and Lucid also make all vehicles sold in the United States domestically. Ford hits 77% U.S. production, while Stellantis sits at 57%. Nissan and GM each clock in at 52%.
Trump’s 25% tariff on non-U.S.-made vehicles kicks in next week, on April 2, 2025. Elon Musk confirmed that Trump’s tariff will still affect Tesla, despite its plants in America.
Musk posted on X about tariff impacts. He said foreign-sourced parts will drive up costs. It’s not a small hit. Tesla warned of this in a letter to the U.S. Trade Representative. “Certain parts and components are difficult or impossible to source within the United States,” the letter stated, even with “aggressive localization.”
Nikola Motor founder Trevor Milton has been given a full pardon by U.S. President Donald Trump in an unprecedented turn of events.
Trevor Milton Media announced late Thursday that the formerly jailed founder of the all-electric automaker that President Trump had “pledged to end the political weaponization of the Justice Department. This pardon marks a step toward fulfilling that commitment.”
Milton was sentenced to four years in prison in December 2023 after being found guilty of multiple counts of fraud.

“I was not a very seasoned CEO,” Milton said after his sentencing. Questions about the legitimacy of some Nikola product demonstrations and several statements that were found to be misleading regarding the company’s progress on its vehicles brought Milton to U.S. Federal Court to face two counts of wire fraud and one count of securities fraud.
Now, he is free.
Milton said in a statement:
“This pardon is not just about me—it’s about every American who has been railroaded by the government, and unfortunately, that’s a lot of people. It is no wonder why trust and confidence in the Justice Department has eroded to nothing. I wish judges would stop believing whatever the prosecutors feed them so Americans could trust the justice system again. Until that happens, our justice system will continue to erode until there is nothing left. The 90+% conviction rate in New York is appalling and is a result of prosecutors getting whatever they want and putting innocent people in prison. I saw firsthand the tactics they use to achieve those guaranteed convictions. I am incredibly grateful to President Trump for his courage in standing up for what is right and for granting me this sacred pardon of innocence.”
Milton will now launch a documentary that is available for preview here.
