We heard earlier that Apple had released their tenth beta of iOS 11 an now we have a speed test between OS 11 Beta 10 vs iOS 10.3.3.
In the video below the iOS 11 beta 10 is compared side by side with the current release which is iOS 10.3.3, the software is run on two iPhone 6 handsets.
As we can see from the video the iOS 10.3.3 booted up faster that the iOS 11 beta 10, this should change by the time the final version of iOS is released.
We are expecting Apple to release their new iOS 11 software some time in the week of the 18th of September. Their new iPhone 8 which will come with iOS 11 is expected to go on sale on the 22nd of September.
