However according to benchmarking company Futuremark, it seems they have debunked those rumors in a benchmark analysis that they have conducted. The company started collecting the data back in 2016 and have collected over 100,000 benchmark results for seven different iPhone models across three versions of iOS.
Based on what they found, it seems that all the iPhone models they tested have performed consistently throughout the years, with some variations that fall within normal levels. In some instances where performance dipped, it was attributed to some minor changes in iOS that in real-world usage should not really be noticed by users.
The company writes, “Our benchmarking data shows that, rather than intentionally degrading the performance of older models, Apple actually does a good job of supporting its older devices with regular updates that maintain a consistent level of performance across iOS versions.” Whether or not this will debunk the conspiracy theories remains to be seen, but if anything these benchmarks actually prove the opposite, which is that Apple actually cares about maintaining its older devices.
