There have been a lot of misleading reports about this data

Apple's Spectre fix reportedly has a huge impact on device performance

Benchmark results have been circulating which showcases the impact of Apple's Spectre addressing iOS 11.2.2 update on an iPhone 6, revealing a huge performance impact of 41% in single-threaded tasks. 

While these results show substantial decreases in device performance and the benchmarker blames the performance reduction on Apple's Spectre patch, it does not get away from the fact that the results here can be easily attributed to Apple's battery/performance scandal and the testing methodology here is flawed.  

Below is a table which highlights the drop in performance seen by Melv1n Tech Product Management, who has already stated that it is his results "could be influenced by the battery throttling".

While many news outlets have already released stories blaming this performance decrease on Apple's Spectre patch, most have omitted the fact that these results come from an iPhone 6 with an old battery and that the user tested iOS version 11.1.2 vs 11.2.2, rather than 11.2.1 vs 11.2.2. These two factors make the performance drop here attributable to Apple's existing battery/performance issues. 

Please note that iOS version 11.2.0 is where iPhone 7 devices were first throttled by Apple to prevent battery issues and that Geekbench found that more iPhone 6 series devices were affected by battery throttling after the same update. This fact alone makes this performance dip seem more attributable to changes in iOS version 11.2.0, rather than the spectre patch included in iOS version 11.2.2.

We have already seen multiple reports from users who have tested these new patches to find much lower performance hits on their iOS devices, with Howtogeek finding several Geekbench results on iOS 11.2.2 that showcase a much smaller performance impact than Marv1n's benchmark numbers.

While this makes for an anticlimactic story, the truth here is more important than the hype. The "40% performance decrease" that you have heard about is likely due to battery issues, not Apple's Spectre security fix.

Nope, on a day to day basis, you won’t. These tests test the phones to the ther limits, no daily app such as browser, Facebook, Snapchat etc that people use today, none uses even 50% of the phones capacity. Not even games does.Quote

I've owned a deliberately slowed down Apple device (original Ipad) and it was awful. Trust me, I noticed it straight away. Everything was like I was walking in treacle. Web pages took ages to open etc.

They will notice it, especially as hefty as it is. Most Apple devices are terribly underpowered any way because of all of the crayon eye candy crap going on.Quote
