The launch of iOS 9 was preceded by Apple's announcement, at the developer conference where it was presented 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 been turned into bricks.
With iOS 8, both the iPhone 4s and the iPad 2 have become useless devices, with whom you could hardly 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 it 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 every 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 the iPad 2 on the market, both with five years on the market and that to this day they continue to receive 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 according to 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 much beyond that date, hence the sales of tablets have slowed down so much in the last two years. Nevertheless, the life cycle of both Mac and Apple TV extends to 4 years, although that does not mean that they stop being functional, as it happens with the iPhone and iPad.
Devices that allow us to update your hardware or any component thereof, such as Mac, allow us to extend their useful life several more years without suffering performance losses along the way. I currently use a Mac Mini from 2010 that I swapped the hard drive for an SSD. Its operation has improved considerably, so it still has a few years of life left without suffering performance losses that make me think about renewing the equipment.
The iphone 4s a useless device ??? But, What are you telling me ? I've been with my 4s for five years and it works better than the first day because I wear it with the standard OS and I don't fall into the update trap. And I have a colleague who uses an iphone 4 with ios 7 and he's doing great. My 4s continues to last the battery for two days with bluetooh, wifi, 3g, music, navigation, calls, etc. Alternating of course, not all at once. But still putting a rod in it and it responds like a rocket.
I imagine that there are many applications and games that you would like to install, but you cannot.
It is what Apple is interested in that we change devices every 3 years at most, with the money they cost they already had to fall in shame.
Currently I have a MacBook pro from 2010 and it works like the first day, an iPhone 4 that my father inherited it and it works well and my iPhone 5s that at the moment works for me as the day I buy it, that if the 5s I go to retire to compare the 6s, not because it does not work, I change it because I want more capacity since the 16gb today is useless and since I change I take the opportunity to update myself
