At present, Apple has announced the important changes of iOS 11.3 in advance. Of course, the most noteworthy thing is to manually turn off the frequency reduction function. Especially for the old iPhones on the list, iPhone 6/6 Plus、iPhone 6S/6S Plus、iPhone 7/7 Plus。 These old iPhones can not only check the battery information in the phone, but also manually turn off Apple's switch limiting the processor frequency!

It is worth noting that Apple has also brought a different experience to everyone in iOS 11.3, such as the new dynamic expression.

In addition, Apple has also enhanced the augmented reality experience in iOS 11.3. The new ARKit 1.5 can present posters, logos and illustrations in an interactive augmented reality experience.
