iOS 11.3 beta 4 - better performance on old iPhone and iPad models

Apple recently launched the 4th Public Beta update for the future iOS 11.3 operating system.
Although nothing remarkable is specified, and the only visible change for users is The return of the "iBooks" application to the old name, after the previous beta versions had been renamed in "Books", we can see a significant change for the better in the performance.

As for, for iOS beta tests we use a iPad mini 4. Device with modest configurations compared to the iPad Pro versions existing on the market at the moment, but running with brio iOS 11.
In the previous versions of iOS 11.3 beta we could see a significant degradation of performance and even think it would be a good idea to make a return to iOS 11.2. We also specify the fact that the new battery resources management functions are not available on the iPad (Battery Health (Beta)), about which Apple says they will be at the user's discretion starting with the update this spring.
The good part is that with iOS 11.3 beta 4, the mini 4 iPad returned to life. Applications and games It runs without interruptions, the interface goes fluently. It remains to be seen if there will be sudden errors and closures.

iOS 11.3 Public Beta 4 is available for all iPad and iPhone holders iOS 11 and registered in Apple Beta Software Program.
