Well for one thing Apple rather famously slows down its old phones and lost a lawsuit over it. Apple has plenty of merits but longevity is definitely not one of them.

This is so false, and has been debunked so many times that anyone still repeating it is simply a liar.

Batteries are consumable items. A great analogy anyone can relate to is car batteries. Anyone with a car knows the battery goes bad. Batteries wear out. A car battery that works fine in the summer may have a lot of trouble cranking over in the winter under the conditions and extra load of a cold engine full of sludgy oil.

The phone battery is no different. Overtime it starts to go bad. What Apple did, was determine through software when a phone battery could no longer support a phone running at full blast. They INCREASED LONGEVITY of the device, by throttling the speed. By making it run slower, it was less demanding and still would work - where it otherwise would have been prone to random shutdowns and crashes because of the degraded battery. This was a much better user experience. They could have skipped this altogether, and people would have just bought a new device. Instead this software throttling made the device last even longer. In fact, laptops have been doing this for decades. Should Apple have told folks? Sure. But anyone presenting this as a profit motive or forced obsolescence is deluded.
