I think the loss-leader model for selling cell phones is the real death clock.  I&#x27;ve owned about a dozen phones over the years, with replaceable batteries.  By the time the battery goes, it&#x27;s a choice between spending $50 to revive a cracked and scratched old phone with lint in every orifice, or spending $0 (plus a plan extension, which you were going to do anyway) to get a brand new, faster one.<p>&gt; Maybe on MacBooks where battery replacement is hard?<p>Isn&#x27;t battery replacement hard on all iOS devices?
