Some Speed Tests on iOS 12 Don't Accord with Apple Promise
Apple recently took to the WWDC stage and promised that their iOS 12 would provide improved performance than the current operating system. To demonstrate this, iOS 12 beta was installed on an iPhone 8. The video below shows that the iOS 12 device is quicker at opening a variety of apps, both Apple’s own as well as third-party apps. However, Apple promised that applications would launch up to 40 percent faster. However, the video does not show speed increasing that fast.
Apple also promised that opening the keyboard would increase up to 50 percent faster. Unfortunately, the side-by-side video shows that the keyboard opens fast just as it does in iOS 11.4. This means that it does not live up to the earlier promises.
In another test done by iAppleBytes to compare iOS 12 performance on an iPhone 5s showed that the handset running the latest version of iOS 12 booted up and almost launched applications faster than iOS 12.4. The iOS made the earlier iPhone slow after iOS 12 update.
According to a Geekbench test carried out by iupdateos of an iPhone 8 with the latest iOS 12 beta version, the multi-core score stood at 10469 compared to another test carried out on iPhone 8 running in iOS 11.4 with a score of 10073.
From the tests above, it is evident that although Apple promised improved performance with iOS 12, there are instances where this operating system fails to deliver as promised. In the older iPhone models, the iOS 12 slows iPhone 6 while in the latest models it actually makes them fast.
And keep in mind, all these tests were carried out on the very first developer-only beta of iOS 12. In general, companies don’t focus on speed improvements until later in the process.So you can expect potentials of Apple’s next operating system.
