The iOS 15 system has recently become a new focus for everyone. If not unexpected, it will be announced at WWDC21 in the early morning of June 8 (next Tuesday).
In addition to officially bringing iOS 15, there will of course be other smart systems under Apple, including iPadOS 15, macOS 12, watchOS 8 and tvOS 15.
Today, some media exposed the list of upgraded models for iOS 15, and iPhone phones that can upgrade to iOS 15 have changed.
Including iPhone 12 full series, iPhone 11 full series, iPhone XS full series, iPhone XR, iPhone X, iPhone 8, iPhone 7 and iPhone SE 2 launched in 2020.
The iPhone 6s, iPhone 6s Plus and iPhone SE (first generation) will be abandoned. And when the news of the release time of iOS 15 is released, Apple will turn off the signature verification of iOS 14.5.1, which is to prevent users from downgrading by themselves.
Users who have already upgraded their devices to iOS 14.6 or iOS 14.7 Beta cannot downgrade back to iOS 14.5.1, but can only upgrade upwards.
So is iOS 15 worth upgrading? According to our previous report, iOS 15 will be greatly changed in the notification center, and the design and functions are synchronized with macOS Big Sur.
And the application icons will be changed to make the desktop more concise, and the icons are redesigned in a “semi-physical” style.
The whole is between mimicry and flattening, which may be called “mimicking.”
In addition, widgets will be optimized and enhanced. In addition to freely placing more widgets, users can also interact with widgets more.
Then there is the Always-on screen display function. Apple may only adapt this function for the iPhone 12/13 series, because this function requires an OLED screen.
It is worth seeing that the main event of the WWDC conference has always been system updates, but in recent years Apple has also launched a new generation of hardware products at the conference.
According to the currently known news, iPad mini, AirPods 3, and the new MacBook Pro 14/16 are all expected to be launched!
