There is a longstanding myth that Apple slows down your older iPhones in order to make to buy one of their newer models, and if you believe this myth, a new study might leave you feeling disappointed.
Futuremark, as a study, tested the performances of various iPhones over a period of 18 months using the 3DMark benchmarking app. According to the results, an iPhone 5S’ GPU or CPU performance stayed almost exactly the same over that time. Other models performed similarly as well.
The study was conducted in response to a Harvard report claiming Apple was deliberately slowing down older phone models. The claim was made on the basis of spike in “iPhone model Gen 1 slow” searches, whenever “iPhone Model Gen 2” was announced.
