Tesla Cybertruck Owners Who Frequently Charge Using Superchargers Show as Much as 5% Battery Degradation in a Few Months – 30 Times More Than Those Who Charge at Home

Cybertruck owners who rely heavily on the supercharger network show battery degradation as high as 5% within a few months. This is 30 times more degradation than those who charge at home.

Tesla has chosen to power the Cybertruck with a brand new, in-house-built 4680 battery, which the EV maker calls the “Cyber Cell.”

This is a departure from Tesla’s long-standing strategy of partnering with battery manufacturers to build the individual cells that go into the vehicle packs.

Tesla developed the batteries for previous vehicles, including the Model S, 3, Y, and X, in partnership with other companies, such as Panasonic, Samsung, and LG Chem.

Alternatively, Tesla also buys commercially available “off-the-shelf batteries” in the case of CATL’s lithium-iron-phosphate cells and BYD Blade batteries.

However, for the Cybertruck, Tesla has chosen to vertically integrate the battery cell manufacturing process. 

Not counting a short Model Y production run powered by 4680 cells with slightly different chemistry, the Cybertruck is Tesla’s first vehicle with in-house batteries.

Given that the 4680 cells are new and have not yet been widely tested on public roads, there is considerable interest in how these Tesla-built batteries will perform in the wild.

Fortunately, several Cybertruck owners have recently shared their battery degradation numbers with us, showing some interesting trends.

Overall, in the first few thousand miles, the trend is that Tesla’s in-house-built Cybertruck 4680 Cyber Cells appear to be holding up pretty well. That’s as long as the owners do not frequently use the supercharger network to charge their trucks.

Some Cybrtrucks, almost exclusively charged at home, have retained 99.86% of their battery capacity after thousands of miles of travel.

However, a few Cybertruck owners who frequently charge using Tesla’s supercharger network have shown as high as 5% battery degradation within the first few months of ownership.

These numbers were shared on the Cybertruck Owners Club forum after Kyle, a Cybertruck owner from San Jose, California, inquired about everyone’s battery health.

Kyle asked fellow Cybertruck owners in the group to share their battery degradation, eliciting several responses.

Here is what Kyle wrote…

“Curious, what’s your battery degradation? I lost 3% in 10 months of driving my Cybertruck (15,000 miles). Post yours below.”

In response, several Cybertruck owners shared how much battery capacity their vehicles lost over the past few months.

On the bright side for Tesla, several Cybertruck owners showed that their trucks have barely lost any battery capacity over their short ownership experience.

For example, Steve, a Cybertruck owner from Dallas–Fort Worth, Texas, shows that his truck has only lost 0.14% of its maximum capacity over the past 8,100 miles.

Jeff, another Cybertruck owner from Virginia, says he only uses superchargers sparingly and shows that over the last 7,000 miles, his truck has only lost 0.16% of its maximum capacity.

These are incredible numbers; if we assume this rate continues, it means Jeff and Steve will retain over 98% of their battery capacity after 75,000 miles.

However, the situation is less rosy for Cybertruck owners who frequently top up their trucks using Tesla’s supercharger network or other fast-charging outlets.

For example, Gus, a Cybertruck owner from Austin, Texas, says that when he bought his Cybertruck, he exclusively charged it using the supercharger network, which caused it to degrade quickly by close to 5 percent.

Gus writes…

“I front-loaded my early degradation by Supercharging exclusively in the first few months, but it’s leveled off.”

Together with his post, Gus shared a screenshot of his Tessie app showing massive degradation over the first few months and later tapering off once he presumably stopped using the supercharger network.

Gus’s Cybertruck now only has 117.6 kWh capacity, down from the original 123.2 kWh when the truck was new. Gus has lost more than 15 miles of range over the past few months.

Another Cybertruck owner, Carlos Thomas from Oakland, California, shares that he also frequently uses the supercharger network and that his truck has lost 3.16% of its battery capacity.

Carlos writes…

“10,000 of the 16,000 plus miles I have driven have been "free" supercharging. I have not charged at home since July 2, 2025.”

Carlos shares that his Cybrtruck now only has 118.6 kWh battery capacity. This is more than 10 miles of range gone.

Another Cybertruck owner from Utah similarly shares that he supercharges his truck one-fourth of the time, and over 14,000 miles, it has lost more than 3% of its capacity.

This is better than the first two Cybertruck owners, who have lost 4% and 5% of their battery capacity, but the Utah owner superchargers less than the other Cybertruck owners.

Overall, looking at Cybertruck battery health for these owners, people who frequently supercharge their trucks experience as much as 30 times more degradation than those who charge at home.

Admittedly, there isn’t enough data here to make a conclusive ruling that frequent supercharging will definitely harm Cybertruck battery packs. However, with more than 30 times the rate of degradation between the two groups, I believe this is at least worthy of further study.
