As is generally the case with these types of release, YouTube channel iAppleBytes has installed both the recently released iOS 12 GM and iOS 11.4.1 on a slew of devices and recorded the results to see if there are any tangible differences in performance.
If you're considering buying any of the fancy new iPhones that Apple announced on Wednesday, and you're already an iPhone user, wait until iOS 12 releases before making a purchase decision. You should see an iOS 12 update. Of course, owning the new shiny gadget is always fun and exciting, but getting more mileage from your current iOS device means you're saving yourself money, and you're also helping the environment.
The operating system will also allow people to designate "down time" when iPhones or iPads can't be used - perhaps a child's bedtime or a grown-up's meditation hour. In order to avoid this issue on the former platform, iOS, Apple throttles devices to a point where you will keep on seeing "normal" battery life, but performance degradation is very evident.
The company is also presenting the new iOS 12 as a system that will make iPhone and iPad experiences faster and more responsive. The OS version is now faster is it is claimed to have up to 70% faster swipe to Camera, up to 50% faster keyboard display and double the speed of app launch under heavy working conditions. It is possible to create a Memoji to match your personality and mood.
Security and privacy is another big focus of macOS 10.4, with Apple enhancing Safari's Intelligent Tracking Prevention to block social media "Like" or "Share" buttons and with comments widgets (gulp) from tracking users without permission.
Users will be able to set limits on time spent in apps.
Notification grouping on the lock screen: Push notifications will be stacked and grouped by app and topic. Even day-to-day tasks like opening apps and navigating around the UI seems to be faster on the iPhone 7 and iPhone 6s running iOS 12 Golden Master. Siri learns your routine and shows up the dedicated shortcut on the lock screen right when you need it.
