'Your AirPods Will Die Soon' -- The Shrinking Charge Capacities of Lithium-Ion Batteries (theatlantic.com)
Some of the same podcasters who first extolled AirPods are now complaining about them, reports the Atlantic:
The battery can no longer hold a charge, they say, rendering them functionally useless. Apple bloggers agree: "AirPods are starting to show their age for early adopters," Zac Hall, an editor at 9to5Mac, wrote in a post in January, detailing how he frequently hears a low-battery warning in his AirPods now. Earlier this month, Apple Insider tested a pair of AirPods purchased in 2016 against a pair from 2018, and found that the older pair died after two hours and 16 minutes. "That's less than half the stated battery life for a new pair," the writer William Gallagher concluded. Desmond Hughes, who is 35 and lives in Newport News, Virginia, has noticed a similar thing about his own set: At first, their charge lasted five hours, but now they sometimes last only half an hour. He frequently listens to one while charging the other -- not optimal conditions for expensive headphones. He's now gearing up to plunk down more money on another pair....
The lithium-ion batteries that power AirPods are everywhere. One industry report forecast that sales would grow to $109.72 billion by 2026, from $36.2 billion in 2018. They charge faster, last longer, and pack more power into a small space than other types of batteries do. But they die faster, too, often after just a few years, because every time you charge them, they degrade a little. They can also catch fire or explode if they become damaged, so technology companies make them difficult, if not impossible, for consumers to replace themselves. The result: A lot of barely chargeable AirPods and wireless mice and Bluetooth speakers are ending up in the trash as consumers go through products -- even expensive ones -- faster than ever....
Of the 3.4 million tons of electronic waste generated in America in 2012 -- an 80 percent increase from 2000 -- just 29 percent was recycled.
The article notes that Wednesday Apple announced a new generation of AirPods -- but "did not say whether the devices would have longer lives."
They also report that Apple "does allow consumers to pay for what it calls a 'battery replacement' for AirPods, but each 'replaced' AirPod is $49."

For Li ion you need to stay below 80% state of charge to extend the battery life. The depth of discharge doesn't matter so much (the 0% level has plenty of safety margin above the true lower limit.)

This is no surprise for anybody that actually understands electronics. 2..3 years is all you get with non-replaceable LiPo batteries and daily use. One of the reasons I consider a phone or other device with a non-replaceable battery to be defective by design and will not buy it.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
