I liked the direction you were going, but I don’t think you made the right comparison. iPhones, for example, are used 30-60% longer (4-10 years) than a Samsung phone (3-6 years). Apple provides software updates for all of their devices for 6+ years.

I’ve had very few devices containing lithium ion batteries that didn’t require a new battery. I have devices from the early 2000s from Sony, HP, Dell, Nikon, and countless others whose batteries have failed.
