iOS beta 10.2.1 3 and iOS 10.2 appear today in a performance comparison, after the first version was launched last night by the Apple company. In the video clips below you can see a comparison made between iOS 10.2.1 beta 3 and iOS 10.2 on iPhone 5, iPhone 5S, iPhone 6 and iPhone 6S, the results being similar to those of the past.
iOS 10.2.1 beta 3 is not faster than iOS 10.2, although the Apple company stated that it has solved some performance problems and improved the user experience. Among all these changes of iOS 10.2.1 beta 3, there is no performance improvement for iPhone terminals, or even Apple's iPad tablets.
Considering that iOS 10.2.1 beta 3 is an intermediate update, we should not expect radical changes regarding the performance of Apple iDevices. This update will fix some performance issues, close some security issues, but won't offer better performance, so don't expect them.
