Verdict: False
This is one of the most persistent idiotic statements about EVs, and it's flat-out wrong.
This is one of the most persistent idiotic statements about EVs, and it's flat-out wrong. EV batteries are outlasting the cars themselves. Many older Tesla models have hit 200,000 to 400,000 miles on their original battery packs and are still going strong. Nissan LEAF models are lasting 10-20 years, far beyond their 96-month, 100,000-mile warranties. On top of that, federal regulations require EV manufacturers to warranty their batteries for at least 8 years or 100,000 miles, so even in a worst-case scenario, you're covered.
Yes, EV batteries do degrade with use, but far slower than people assume, and nothing like the cell phone in your pocket. EV packs lose roughly 2.3% of their capacity per year on average (Geotab's 2026 study of about 22,700 EVs), meaning after 10 years you'd still have about 77% of your original range, above the 70% line most battery warranties guarantee. Most owners never come close to wearing one out before selling the car. The "they're just like phone batteries" comparison is the part that really falls apart: phone batteries get a full charge cycle nearly every day and live in a thin case with almost no thermal management. EV packs have sophisticated liquid cooling and heating, are cycled gently (most owners only use 20-40% of capacity daily), and are engineered for a totally different lifespan. Comparing the two is like comparing a commercial airplane engine to a lawn mower.
If you want to extend battery life even further, the playbook is simple: avoid relying on DC fast charging for everyday use, don't leave the car baking in extreme heat or freezing for long stretches, and try to keep the state of charge between 20% and 80% when you can. Do that and the pack will likely outlast everything else on the car.
