Apple recently hosted its annual WWDC 2021 event and announced a bevy of new software updates for the iPhone, iPad, Apple TV, Apple Watch, and Mac. While the forthcoming updates have a lot to offer, one of the things that we are looking forward to is improved performance on all devices. Henceforth, we now have a visual cue of how iOS 15 beta 1 compares against the current iOS 14.6 in speed or performance test.

With every major release of iOS, we have observed that the company slows down the user experience on older as well as some newer models. It could potentially be true that older hardware can not take much from the latest releases and slows the performance down. However, not all of us can upgrade to a newer model and it would be great if Apple can do its software magic and keep the performance up to the usable level. This brings our attention to the new iOS 15 beta 1 speed test comparison against iOS 14.6.
