In order for an iOS build to be installed on your iPhone, it needs to be "signed" by Apple's servers.

Recent reports have warned that Meltdown and Spectre fixes will decrease processor performance.

But it turns out not every user is that lucky.

According to Melv1n - a self-described tech product management blog, whose founder of the same name touts over a decade of experience building and managing tech products - his iPhone 6 took as much as a 41 percent performance hit in single-core benchmark scores after updating to iOS 11.2.2. Both handsets appear to be about the same in the apps. As for multi-core, it went from 2,665 to 1,616, which is a 39% decrease in performance. Those figures fell to 924 and 1,616, respectively, with iOS 11.2.2. Scores for certain tests, like those that run HTML5 and SQLite, suffered the most.

Apple has a history of rarely looking back on anything it has moved beynd - it won't re-incorporate hardware that it has once removed, and it certainly won't let you use older versions of its iOS once you've updated your device. We'll update to the latest versions and note any changes below.

It could be that there are other factors at play here; we would need to see benchmark tests on a greater number of units for a more accurate picture. As to whether or not you should skip the iOS 11.2.2 update, you probably shouldn't since a phone with decreased performance is probably better than a phone with a security flaw and getting hacked.

Have you noticed any changes in performance since installing Apple's latest update?
