The launch of iOS 9 was preceded by the announcement of Apple, at the developer conference in which it was presented by iOS 9, in which it stated that one of the priorities of that latest version of iOS, would focus on improving the performance of older devices, that after the arrival of iOS 8, the older models had become bricks.
With iOS 8, both the iPhone 4s and iPad 2 have become useless devices, with which you could barely perform tasks. But in the successive updates the performance of these two devices was improving a lot, until the final version of iOS 9 arrived and declined again, although subsequent updates have improved the fluidity of both the iPad 2 and the iPhone 4s.
Apple has posted on its website a section called Questions and Answers, in which it tries to solve the most common doubts that both future and current users may have. As we can see in the question related to the useful life of its devices, we see how according to the company it states that in order to continue enjoying all the features that the company adds each year, our iPhone must have a maximum of 3 years of life.
According to Apple, the estimated life cycle of an iPhone is 3 years, although as we all know, we still find the iPhone 4s and iPad 2 on the market, both with five years in the market and that today they are still receiving updates and are functional, although we cannot enjoy all the news due to the limitations offered by the old hardware that we find inside.
In the same section, we can also read as per the company, The life cycle of the iPad and Apple Watch is also three years, although in the case of the first, we know that users are stretching it well beyond that date, hence the sales of tablets have slowed down so much in these last two years. But nevertheless, the life cycle of both Mac and Apple TV is extended to 4 years, although that does not mean that they cease to be functional, as is the case with the iPhone and iPad.
The devices that allow us to update their hardware or some component thereof, as is the case with Macs, they allow us to extend their useful life for several more years without suffering performance losses along the way. Currently I use a Mac Mini 2010 to which I changed the hard drive for an SSD. Its operation has improved considerably, so it still has a few years to live without suffering performance losses that make me think about renewing the equipment.
