IOS 8.1.2 vs iOS 8.2 Beta 3 on iPhone 4S - YouTube


In the behavior comparison, two 32 GB iPhone 4S models were used, both of which were restored to their original factory condition and similar contents are stored in the terminal.


Wake up the terminal from the sleep state first.


There is almost no difference in this behavior.


First open "Message".


The speed to display each message seems to be "iOS 8.2 Beta 3" is faster by several comma


There is no difference in the speed of text input.


"Calendar" or ...


The starting speed of "photo" is almost the same.


Open an individual image ......


I also do pinch-out and pinch-in operations, but the operating speed does not change at all.


There is no big difference in camera startup speed.


"IOS 8.1.2" slightly won the start of "weather".


Launch "map" of plain. The speed until the map is displayed on the screen is about the same, but the map of "iOS 8.2 Beta 3" has a larger amount of information.


"IOS 8.1.2" is a bit smoother for the zooming action of the map, while those of "iOS 8.2 Beta 3" took a while to render the map.


If the operation like "memo" is light-weighted, there is no significant difference in operating speed between the two OSs.


This is taking time to display the screen ......


It is the App Store. "IOS 8.2 Beta 3" side is overwhelmingly short on the time it takes to launch the application and display the screen.


Next was the "setting" that opened. You can confirm that "iOS 8.2" is installed on iPhone 4S on the right side.


Launch "YouTube".


The speed until the movie is displayed on the screen is almost the same.


However, when I tried playing the movie, the iPhone who installed "iOS 8.2 Beta 3" began playing the movie first.


It will take some time to launch the "Facebook" application.


For a moment text and images are displayed on "iOS 8.1.2" side ......


I will immediately turn white and continue loading. Meanwhile "iOS 8.2 Beta 3" almost completed loading of text and images.


So iOS 8.2 Beta 3 seems to be faster for Facebook display.


The end is "Geekbench 3Compare benchmarks with.


Since we are using the same exact same model as the iPhone 4S 32GB model, the benchmark results are almost the same.


What I found out as a result of comparing the activation and operation of multiple applications is that 'iOS 8.2 Beta 3' is somewhat quicker in operation than 'iOS 8.1.2'.
