Keith, a Cybertruck owner from New York, says he’s worried about how fast his truck is losing battery capacity.
Keith is a power user when it comes to his Cybertruck and has already put over 43,000 miles on it in about a year.
During this period, Keith says his truck has lost a total of 17 miles of range, with about 13 miles of range lost at 80% charge, which is the level he typically charges his vehicle to.
Keith mentions that at 80% charge, his range used to be 254 miles, but it has now dropped to 241 miles.
Concerned about this rapid battery degradation, Keith shared his worries on the Cybertruck Owners Club forum.
He writes…
“Range Slowly Disappearing
My range is disappearing. At 80%, I used to get 254 miles. Now I only get 241. I’m trying to post a video of my phone showing 80% and 241, but it’s not working.
Has anyone checked the range at 80%? I just hit 43,000 miles.”
Keith seems unhappy with the range loss. However, other Cybertruck owners suggested this might not be an actual loss but instead a misreading.
Gus, from Austin, Texas, commented…
“It’s normal and expected for the rated capacity to fluctuate and decrease over time.
My charted capacity increased significantly after a road trip where I ran it down to nearly empty and charged it to 100%.
This didn’t change the cells but provided better data for the computer to estimate. (EDIT: I normally charge to 50% for daily use.)
Overall, the kWh capacity will decline with time, which is unavoidable.
Mike, another Cybertruck owner from Texas, added…
“Try depleting the battery to 10% and then charging it back. It might change your estimated range.”
A third Cybertruck owner from Washington explained…

“If you are short-cycling the battery (not fully depleting or fully charging it recently), the battery calibration can drift over time.
The Battery Monitoring System estimates the state of charge (SOC) by measuring energy in and out, but this estimate needs recalibration at very low and very high charge levels for accuracy over time.
It recalibrates automatically when you run the battery down to a low SOC and recharge to around 90%.
Historically, with Teslas, losing about 6% of range in the first year or two is normal. Battery capacity loss tends to be greatest in the first couple of years and then tapers off over the next decade or more.
My own Cybertruck has shown minimal initial battery degradation. After 17 months parked outside 24/7, it reports zero degradation. I also periodically cycle the SOC, trusting my battery calibration is accurate.
A fourth Cybertruck owner noted…
“The battery measurements are imprecise.
Tesla will replace the pack under warranty if its capacity falls below 70% due to degradation.”
Most commenters agree that Keith’s Truck isn’t actually losing range; rather, the system might just be giving inaccurate readings because he hasn’t recently cycled the battery from 10% to 90%.
Yet, Keith remains unconvinced and expressed displeasure with Tesla’s promise to replace the battery pack for free if the range drops to 70%.
He asked…
“But what is considered a failing battery? 254 miles to 241 miles is quite a bit of range loss. It was 243 a month or two ago.”
Another Cybertruck owner, Jasper from Atlanta, Georgia, echoed this concern…
“I have just over 18K miles and noticed a decrease in range. When I first got it, it showed 100% as 302 miles. Now it shows 298 miles.
I’m not worried YET. Yeah, I know about the battery warranty, but we’re talking about dropping to 215 miles on a full charge. Am I going to wait until it gets that low?
A 215-mile range for a Cybertruck is definitely concerning; however, please let me know what you think in the comments. Share your ideas by clicking the red “Add new comment” button below. Also, be sure to visit our site, torquenews.com/Tesla, regularly for the latest updates.
