# iOS 26 vs. iOS 18: A Performance Assessment

iOS 26 brought forth a notable redesign featuring its Liquid Glass look, which has received varied feedback concerning performance. While several users have noted decreased performance on their iPhones following the update, John Gruber from Daring Fireball recently took another look at iOS 18 after using iOS 26 for a considerable time and shared his observations on the performance discrepancies.

## John Gruber’s Insights

In a recent entry, Gruber elaborated on his time spent with an iPhone 16 Pro operating on iOS 18.7.7 as his primary device for two days. He observed that, counter to some claims, iOS 26 felt swifter than iOS 18. Gruber emphasized that during iOS 26’s beta stage, Apple had fine-tuned several system-level animations, which aided in creating a sensation of speed.

### Primary Insights

Gruber highlighted that the pace of animations has a significant impact on how users gauge the overall performance of their devices. He remarked, “So many little things feel slower” on iOS 18, even if the actual performance data might not reflect a considerable disparity. The slower animations in iOS 18 rendered the system feel less agile, especially when navigating back to the Home Screen.

One of the most marked enhancements in iOS 26 was the speed increase in app launching animations, which became much quicker in beta 6. This adjustment not only improved user experience on newer devices but also made older iPhones feel more lively.

## The Effect of Animation Pace

The sensation of speed is frequently shaped by how quickly animations respond. Gruber’s experience indicates that while iOS 26 might have introduced some performance challenges, the overall impression of the operating system is enhanced due to swifter animations. This aspect is especially pertinent for users considering a transition from Android, as they may observe these distinctions more sharply.

## Downgrade Possibilities and User Experience

Gruber’s capability to juxtapose the two operating systems arose from his possession of an older iPhone still operating on iOS 18. The concept of permitting users to seamlessly toggle between iOS versions could yield valuable perspectives on performance variations, yet currently, Apple does not support such downgrades.

## Summary

The discourse around iOS 26 and its performance compared to iOS 18 underscores the significance of user experience in software development. While some users may have encountered slowdowns with the recent update, Gruber’s observations imply that the overall sensation of iOS 26 is quicker, primarily due to enhanced animation speeds. As users progressively acclimate to the latest updates, their experiences will influence the ongoing conversation about performance and usability within Apple’s environment.
