Apologies about this part, you are correct that this wasn't your words, the rest of what I wrote I still stand behind. Mostly, it's a problem that you seem to believe that because of incremental improvements in battery technology, we're at a point where it's acceptable to make devices an end-user can't service. That we can't design for water/dust ingress protection and have an easier to replace battery.

Realistically batteries currently made reach end of service life around 3 years, previously it was around 2. People using devices heavily (gaming/videoconferencing) or living in hot climates will have shorter service life. You can push them past the 80% health threshold, but then it's throttling, risk of bulging, etc. You got 9 or so years out of a SE using the battery long past its service life.

But you, (yes, you!) act like everything's currently fine with designs and that we won't burn up the batteries sooner. I'm saying that is misguided and it doesn't line up to the reality you've experienced directly (which is that batteries are still a consumable that need to be replaced eventually). You probably haven't got your hands dirty to DIY, nor are you aware of how they made it harder than it has to be (some manufacturers don't put adhesive tabs on the batteries to pull off). You don't understand that it's possible for the engineering divisions to design a no compromise device that's easier to service and the only reason manufacturers don't is because of the pervasive mindset of: 'Well the battery is cooked, time to buy a new device'. Apple basically still designs their devices for maintenance, but they did it in a way to require specialized equipment.

You're clearly not a device lessee if using the device that long, so why have lessee mindset?
