Tesla says Model S and Model X batteries degrade about 12% after 200,000 miles
Tesla
Tesla owners often are asked about the lifespan of their vehicle's battery and whether it will need to be replaced. However, based on over a decade of real-world data, Tesla confidently states that battery replacement is not a concern for most customers. On average, Tesla batteries degrade by a mere 12% after 200,000 miles (321,868 km) of usage, which outperforms many expectations.
The impressive durability of Tesla batteries has been demonstrated through the company's consistent investment in research and development. As a result, Tesla has consistently pushed the limits of battery technology, ensuring that their electric vehicles remain at the forefront of the industry regarding performance and sustainability.
Mileage vs. Age: Factors Affecting Battery Capacity Retention
Though mileage is a significant factor in battery capacity retention, battery age also plays a crucial role. Lower mileage retention figures likely indicate the impact of age, while higher mileage values from high-utilization vehicles probably reflect less influence from battery age. Tesla's data set spans over a decade and provides valuable insight into the complex relationship between these factors and battery degradation over time.
This information is invaluable for current and prospective Tesla owners, as it helps alleviate concerns regarding battery lifespan and potential replacement costs. Furthermore, it emphasizes the long-term sustainability of EVs, making them a more attractive option for environmentally conscious consumers.
Newer Battery Chemistries Promise Even Better Performance
Tesla continues to innovate and improve its battery technology. The company is developing newer chemistries that promise to perform even better than the current ones. As more data becomes available, Tesla plans to expand its disclosure on these new battery chemistries to keep consumers informed about their vehicles' battery performance.
Electric Vehicles Becoming More Sustainable and Cost-Effective
The durability of Tesla batteries benefits the environment by reducing waste from battery replacements and contributes to making EVs more cost-effective for consumers in the long run. As the market for electric vehicles continues to grow, the impressive performance of Tesla batteries will play a significant role in encouraging more people to switch to sustainable transportation.
In conclusion, Tesla owners can rest assured that their vehicle's battery is built to last. With just a 12% degradation after 200,000 miles on average and the potential for even better performance in the future, Tesla continues to demonstrate its commitment to sustainability and innovation in the electric vehicle industry. This commitment is evident in the company's ongoing efforts to develop new battery chemistries and to share detailed information about battery performance with the public.

Following yesterday’s news that the Tesla Robotaxi network is ahead of schedule and set to launch on June 12th, overnight, Elon confirmed that the Robotaxi network is far ahead of expectations.
With Elon back and working full-time at Tesla, SpaceX, and xAI, we’ll likely receive a lot more updates on what these companies are working on. In this case, Elon confirmed that Tesla has been running autonomous Model Ys with no one in the driver’s seat on Austin’s public seats, with no incidents. According to yesterday’s report, there is still someone in the passenger seat just in case something comes up, but essentially “driverless.”
Elon also confirmed that Tesla’s ambitious plans to have a Model Y deliver itself directly from the factory to a customer, presumably in Austin, will also occur next month.
For the past several days, Tesla has been testing self-driving Model Y cars (no one in driver’s seat) on Austin public streets with no incidents.
A month ahead of schedule.
Next month, first self-delivery from factory to customer.
While this will likely be geographically limited to the areas around Giga Texas, and potentially, Tesla’s Fremont factory in the future, it is still a great step toward reducing the cost of vehicles.
In a reply, Elon also confirmed that anyone would be able to test out the Robotaxi network by the end of June. While in typical Elon fashion, he didn’t answer the question of whether the network will be invite-only at first, we expect this will likely be the case and it won’t just be anyone who can open the Tesla app and summon a robotaxi.
At the Q1 2025 Earnings Call, Elon stated that the Robotaxi service would only be available to the public in late June or early July, giving Tesla enough time to test with internal audiences, as well as invited testers. This timeline seems to be fairly concrete, but if you’re planning a trip to Austin to check out Robotaxi, we suggest looking at early July, as timelines can still shift.
Tesla’s Optimus X account recently dropped another video, following up on its previous dance routines. Previously, Optimus demonstrated impressive footwork, along with a level of agility and balance that has improved immensely since Optimus was first unveiled.
In a new video posted to X, Optimus is seen doing actual work. While it’s still in the early days, Tesla shows off how the robot is learning to perform small tasks.
The real focus of the video isn’t on the tasks Optimus is performing but on how it’s learning to perform these tasks. Optimus is learning by watching humans perform the work through a first-person view.
The video demonstrates Optimus tackling daily tasks that require a good degree of dexterity and environmental awareness, including vacuuming, cooking, and even taking out the trash. While the previous demonstrations were more of a showcase of Optimus’ physical capabilities, this one is more about the learning process.
The key breakthrough, which was emphasized by members of Tesla’s Optimus AI team, is the robot’s new ability to learn complex, bi-manual tasks largely from watching videos of humans performing them. This results in a reduction in direct teleoperation, where real humans control Optimus remotely to generate training data.
Murtaza Dalal, a member of Tesla’s Optimus AI team, shared his excitement about the development - and noted that while teleoperation doesn’t scale, training by watching video does scale — extremely fast.
First-Person Perspective
The ability to learn from human video (while currently focused on a first-person perspective) means Optimus can bootstrap new tasks much faster than before and with less human interaction required. Milan Kovac, an Optimus Engineering team member, elaborated on this, stating:
“We recently had a significant breakthrough along that journey, and can now transfer a big chunk of the learning directly from human videos to the bots... Many new skills are emerging through this process, are called for via natural language (voice/text), and are run by a single neural network on the bot (multi-tasking).”
What’s Next for Optimus?
The road doesn’t stop here. The Optimus team is already looking to see where they can push the barriers of learning, and is looking at having Optimus learn directly from internet videos of humans doing tasks. This means learning from third-person views rather than the more optimized first-person views that it is currently learning from today.
Once Optimus can translate the third-person perspective to the first-person, much like humans do, then it opens up a whole new world of training data. Optimus will be able to learn simply by watching the world around him.
All this rapid advancement is critical for Tesla. Elon has doubled down on Optimus being Tesla’s key to unlocking the biggest market in the world, and it is key to pushing Tesla’s new vision of sustainable abundance.
This is just the first step in a long process - we’re still years away from Optimus making its way to customer homes, but the journey has to start somewhere. For now, it’ll be working hard in Tesla’s labs and factories, and we expect to hear more about Optimus later this year once the production line is up and running.
