Because iOS 17 no longer supports the upgrade of many old iphones, the iphones tested this time are iPhoneXR, iPhone 1 1, iPhone 12, and iPhone 13, which are also relatively large in the market. After upgrading iOS 17, the battery life of iPhoneXR, iPhone 1 1, iPhone 12 and iPhone 13 is 5 hours, 19 minutes, 5 hours and 23 minutes, 6 hours and 3 minutes and 8 hours and 4 minutes respectively.
The second is iPhone 12, the third is iPhone 1 1, and the fourth is iPhoneXR. The battery health of four iPhones has not changed after upgrading iOS 17. Compared with iOS 16.5, the battery health of the four iPhones after the upgrade of iOS 17 is still 9 1, 100, 98 and 97 respectively. After upgrading iOS 17, the battery health of iPhoneXR, iPhone 1 1, iPhone 12 and iPhone 13 has not shrunk.
Ios built-in applications:
1, multitasking
Multitasking is always a shortcut to switch between applications. Because iOS will know when you like to use the app and update your content before starting the app. So, if you often check your favorite social app at 9: 00 in the morning, then the relevant content you are concerned about will be available at any time. This is the multitasking function of iOS, and I have thought of it for you before I did it. Click the Home button twice to see the preview screen of the open application.
2. camera
The camera function of iOS puts all shooting modes in a prominent position, including photo, video, panoramic mode and new square mode. With a light sweep, you can shoot the picture you want in the way you like, just in an instant. And the new filter can make you enjoy each photo better. It can add retro flavor to photos, improve contrast, or feel the charm of black and white, so that you can give full play to your artistic creativity.
