The battery life of iPhones, iPads and iPod Touches running iOS 9.2.1 and iOS 9.3.1 was tested in an extended video clip to show us how big the difference is, for better or worse, between the two versions of the operating systems offered by the Apple company.
iPhone 4S, iPhone 5, iPhone 5S and iPhone 6 are the terminals for which it was tested battery life on iOS 9.2.1 and iOS 9.3.1, and as you can see from the image below, the difference is imperceptible in the daily use of our terminals.
To test the battery life of iOS 9.2.1 and iOS 9.3.1, the Geekbench application was used, which has a special test that checks the duration of use of iDevices through a series of proprietary tests, so that a user can quickly find out how long the autonomy of the battery of his device is good.
Of course, the period of daily use will be longer than that of the tests because the terminals were all the time with the screen turned on at maximum brightness and the components were stressed to the maximum, but the final result is valid and matters the most in the end.
