Analyst estimates average lifespan for all Apple devices at over four years
The average lifespan of an Apple device is probably just over four years, according to analysis into figures released during the fourth quarter investor conference call, suggesting that iPhones and iPads remain in active use for twice as long as the typical consumer iPhone upgrade cycle.
The analysis by Asymco's Horace Dediu is based on figures provided by Apple each quarter specifically the number of devices it sells. It is also based on another rare figure revealed by Apple during the financial results, namely that it had grown its active install base to 1.3 billion devices, representing a 30 percent growth over two years.
This latter figure is the second time Apple revealed its active installation base, with the first being when it hit the 1 billion active device milestone, as part of the results released in January 2016.
Dediu advises that by knowing the number of active devices, as well as the cumulative number of devices sold, it can be used to approximate the average device lifespan.
To do so, he created a graph to show the total number of devices Apple sold since the second quarter of 2007, followed by a curve to show approximately how many active devices there are, based on Apple's released figures. For a particular quarter, the area of the graph below the line relates to the number of active devices, while the area between the active device curve and the number of devices sold determines how many devices have been retired since 2007.
The approximate lifespan of a series of devices is said to be when the cumulative number of devices sold in the quarter equates to the amount of retired devices in a later quarter. The duration between the two can effectively be taken as an estimated average lifespan for the devices.
To work out the estimate lifespan of devices retired in the recent quarter, Dediu determines the number of retired devices to be 750 million, namely 2.05 billion cumulative sales minus 1.3 billion active devices. This is then compared to earlier quarters until it is close to the number of cumulative devices sold.
"The lifespan is thus estimated at the time between now and Q3 2013, or 17 quarters or about 4 years and three months," advises Dediu.
The cumulative devices calculation includes Macs, iPhones, iPads, iPod Touch, and the Apple Watch. As such, the calculations cannot be broken down to individual product categories, and considering some hardware types would be assumed to be used for longer than others, it would be hard to work out these figures without Apple providing more detailed statistics, something it is unlikely to provide anytime soon.
A second graph by Dediu maps the average lifespan for devices retired in a particular quarter, based on the first graph. Notably, the graph seems to show the average lifespan increasing every few quarters since 2012, breaking four years in early 2017, and seemingly indicates the trend of using Apple devices for longer periods of time will continue for a while longer.

Now that battery age is in the minds of the public, and more people are changing out batteries, the average age will only tick up.
My old iPad 2 is what — six years old? Still running fine as my daughter's primary computer.
My living-room iMac/TV is ten years old. Working fine, 24/7.
My iPod 1st generation is now 17 years old and still running fine.
My iPod classic is — gosh, ten years old? Twelve? Works fine.
My iPhones, I sell off and don't keep track of.
Hm. Am I an outlier?
4 years on average? Sure. But sort of a useless statistic.
Typically, we keep our phones for three years. So, guess that averages to 4 years in our very tiny sample size. Not including older iPod Nanos that are kept in the car or for use at the beach and are not online anyway.
A quick search on eBay brings up plenty of iPhone 4 listings and these are from as early as 2010. I'd consider his number to be the starting point for the real number which no one will ever know unless Apple publishes the number and even that would be a guest because no ones knows the phones that have been repurposed or being used on networks of which there is no way to measure model usage.
This is why Apple has an installed base of 1.3B users on IOS, no hardware company has that kind of installed base, Google said the have install based on Android but they do not make money off them. Samsung who sells more phone can not claim they have such a large installed base.
For some reason?
You'd have to guess size is a factor.
The X is popular and packs all that tech in to a phone basically same size as normal sized 6,7,8.
Though waiting for a 2018 SE probably makes more sense at full price. A used one, however..,
