Lithium-ion batteries generally degrade fastest when held at a high state of charge, which means keeping your iPhone or your Mac's battery at 100 percent accelerates the chemical wear that permanently reduces its actual capacity over time.
Battery degradation on high-mileage EVs is not as big a deal as some might make you believe. Real-world data shows that EVs with over 150,000 miles are still going strong, with minimal degradation. Older EVs are more affected by high mileage, but technology has made newer models more resilient. Battery degradation is inevitable, but new research shows that EV owners should just keep driving their cars without worrying about what happens with the thousands of cells that live in their cars' floors.
Everyone is entitled to their own opinion, but that's pretty demonstrably false. It's a good reminder that consumer sentiment often lags the reality on the ground. Americans don't have a damned clue who makes good EVs. That's what I took away from the January, 2026 edition of the Electric Vehicle Intelligence Report, which measures consumer sentiment toward EV brands. Surveyed consumer sentiment toward EV brands seems to be based on vibes and internal-combustion car experience, not anything resembling reality.
