Tests do not cheat, Apple does not slow down your old iPhone



Finnish benchmark company Futuremark has set out to discredit speculation that Apple intentionally slows down older iPhones when it releases new software updates. It would, according to some, be a way to encourage their customers to buy new devices .

In 2016, Futuremark has compiled more than 100,000 benchmark results for seven different iPhone models in three versions of iOS, using that data to create performance comparison charts and to determine if performance declines have occurred in iOS 9, iOS 10 and iOS 11 .


The first device tested was the iPhone 5s , as it is the oldest device capable of running iOS 11. The iPhone 5s, released in 2013, and was the first iPhone to have a 64-bit A7 chip. We recall that iOS 11 is limited to devices of this architecture. Futuremark used the 3DMark Sling Shot Extreme Graphics test and calculated all the benchmark scores of the iPhone 5S over a given month for comparison.


The higher the bar, the better the performance , and based on the tests, the performance of the GPU in the iPhone Ss has remained constant from iOS 9 to iOS 11 with small variations that Futuremark says " fall within normal levels ".


The performance of the CPU of the iPhone 5s over time was measured using the 3DMark Sling Shot Extreme Physics test, and again, the results were largely consistent .


Graphics for other devices, including the iPhone 6, 6S and 7, show some lows and increases when it comes to GPU performance. In them, the performance of the GPU is higher compared to previous versions of iOS .


The performance of the CPU in these three devices has decreased slightly, something that Futuremark attributes to " minor iOS updates or other factors ." " It is unlikely that a user will notice this small difference in daily use ," the site says. Based on his comparisons, Futuremark states that " there are no signs of a conspiracy ".


Benchmarking data shows that instead of intentionally degrading the performance of older models, Apple really does a good job of supporting their older devices with periodic updates that maintain a consistent level of performance in iOS versions.


However, the RAW power of the CPU and GPU devices does not provide a complete picture of performance on an old device that has been upgraded to a new operating system, nor are benchmarks an accurate measure of real-world performance. Apple may not deliberately slow down older devices with their software updates, as some have speculated, but there are other factors to keep in mind .


New features that consume more system resources can make a device feel slower, as well as more system-intensive design elements and other adjustments and changes designed for newer devices that are more powerful.


Apple's operating system upgrades also introduce more advanced APIs and technology for its newer devices , leading to integrated, third-party applications that target more powerful devices and can not be optimized on legacy devices, resulting in a older device sits slower than a newer device following an iOS update.


Sometimes, there are also early bugs in the software that need to be corrected through additional updates . For example, there are complaints of slowing applications and performance losses on users who have installed iOS 11, problems that can be solved with Apple tweaks and iOS 11 operating system updates.
