I can get the battery replaced on my phone for a fraction of the money it would cost me to buy a new phone. So I have to take it in to the shop for an hour. Big deal. I can do that once every few years. And I can still use wired headphones with my phone even though it doesn't have a headphone jack. Sheesh, I wonder how that works.

The biggest anti-consumer practice to make your device lifespan as short as possible is whatever software update practices the manufacturer has. Annual major versions increase hardware requirements - I can tell every day how my 5 year old phone is getting long in the tooth. Lack of long-term software support is another way to make sure the average user buys a new device well before the old device has reached end of life.
