Ever wonder why your iPhone suddenly needs replacing after a couple of years? It’s a problem that people have been talking about as far back as 2007, when Apple’s first iPhone was released.
Suspicion over the iPhone’s longevity was initially brought up over its battery. Unlike the flip phones of yore, the iPhone’s internal battery was not user-replaceable. Early on, critics suggested that the battery would last for 400 charges, or 2 years of use, before customers would have to go in and pay for a battery replacement (costing $79 today).
