Apple’s Spectre Fix for iOS does not Necessarily Slow Down iOS Devices

Something worth noting for iOS users

A few days ago, Apple issued iOS 11.2.2, which addresses the Spectre vulnerability affecting a big bunch of processors. As reported a few days back, many developers state that addressing the Spectre vulnerability would lead to compromises in overall performance. While there are initial reports that iOS devices updated to iOS 11.2.2 experienced a drastic decrease in performance, I decided to check it myself using my 64GB iPhone SE. For the test, I used AnTuTu to gather the scores.


Here’s a screenshot of a spot AnTuTu test I did last September 22, 2017. Back then, my iPhone SE was running iOS11.0:


Here’s a screenshot of today’s AnTuTu’s testing, with my iPhone SE running iOS 11.2.2. Though there are many reasons that it should slow down since 1) because of iOS 11.2.2’s Spectre patch, and 2) because my iPhone SE is over a year old, the results say otherwise:

If you do the math, there’s a 0.6% improvement in overall performance with iOS 11.2.2 in comparison to the iOS 11.0. While this may be a case-to-case basis, this might bring in some hope that there’s a way of patching the Spectre vulnerability without compromising overall performance. In fact, there are a few users who got the same results as mine (check them here, here, and here).

However, given the battery debacle Apple has been facing these past few weeks, I was expecting a supposed decreased performance since my iPhone SE is already more than a year old. One question remains: Did Apple decided to remove its performance-compromising feature with iOS 11.2.2 for old iPhones? Regardless if Apple made major changes to iOS 11.2.2 or not, please do update your iOS devices to protect yourselves from Spectre.
