These lithium-ion batteries do not degrade in a fixed timely manner but rather just lose 70% in a matter of a couple of days after some years have passed, no matter if used heavily or not. They are composed of chemicald which degrade over time. With larger laptops batteries for example the effect is more dramatic.
Comparable to the liver which doesn't degrade sequentially with excessive drinking but shows signs of cirrhosis rather abruptly after years of drinking abuse.
Also the argument that you couldnt change the battery yourself I can't agree with because I was talking about repairabality in general, no matter if you do it yourself or let a repair shop do it, which I reckon most people go to.
Yes most lithium-ion batteries are fixed and not user replacable but thanks to aliexpress, ebay and taobao you can find almost any of them and replace them or let someone replace them.
There is no good argument to sacrifice a case that can be disassembled with screws with one that is glued or uses tabs in sacrifice for thinness both in terms of durability and longevitity.
