There is a report that when a new iPhone variant or a new upgrade is rolled out by Apple, the older variants tend to get slower.

Apple faces a lot of flak over this. So Futuremark, a benchmarking company preformed a test on this matter and the result posted on the company’s website notes.


Company claims that it has been done over 100,000 benchmarking tests on iPhones from 5s to iPhone7. Then they averaged the performance of the processor and the graphics chip once a month for 18 months from April 2016 to September 2017. The tests were done on the devices, which had iOS 9, 10 and 11. 


Futuremark explained in its post,” GPU performance remained consistent for iOS 9,10 and 11 with only minor variations that fall well within normal levels.”

Also said that it was clear that iOS updates do not have a effect on the performance of the device.  If there was any dip, users sill would not notice on a daily basis.


There are some factors that might affect people’s perception of performance after updating an older device with a newer version of iOS. The update might add new features that use more resources or require more processing power. Further noted.” The realty is that your iPhone doesn’t slow down every time a new update or a variant is launched.”
