I can only speak to corporate use, but the most common issues I saw were battery life, charging port issues, and speaker failures, in that order. I managed about 1200 for about 2 years and I'd get 1-3 of those issues a week. I'd say 25% of the time it required a replacement. Average age 2.5 years.

That’s repairable for cheaper that buying a new one, isn’t it? Perhaps the rationale is that it’s cheaper because the resell price offset the repair price?

		Yeah you get a few bucks back from recyclers or your carrier but also having to inventory phones and track them is a pain in the ass and requires staff to manage. Much easier to just toss it and send em a new one next day.
