Electric cars could last much longer than you think (wired.com)
EVs are practically worthless secondhand, because the huge batteries will need expensive replacement after a few years. At least, that’s what some articles or forum discussions in recent years may lead you to believe. However, while secondhand prices for EVs have been plummeting, evidence is building that their batteries could last longer than the eight-year warranties most come with.

Apple's 80% charging limit for iPhone: How much did it help after a year? (macrumors.com)
With the iPhone 15 models that came out last year, Apple added an opt-in battery setting that limits maximum charge to 80 percent. The idea is that never charging the iPhone above 80 percent will increase battery longevity, so I kept my ‌iPhone‌ at that 80 percent limit from September 2023 to now, with no cheating.
