the other day, Apple officially launched iOS 8.1.1 update patch Apple said iOS 8.1.1 will improve the performance of older devices based on iOS 8 and using A5 chips, that is, iPad 2 and iPhone 4S.

After the upgrade, Ars Technica, a foreign website, tested the effect.

From the test results, compared with iOS 8.1, the iPhone 4S app starts faster, but by a small margin. However, compared with iOS 7.1.2, the gap is still obvious.

Apple has improved the A5 processor performance of the iPhone 4S and iPad 2. Although both devices have 512MB RAM, the reload time is significantly improved when multiple tabs are opened in Safari, and multiple tasks are used to switch out and return to Safari.
