Apple released iOS 12 on Monday, September 17, 2018.
The world is only two days away from Apple's fall 2018 keynote. Wednesday promises to reveal a several new pieces of hardware, including a new iPhone lineup and major improvements to the Apple Watch. Apple is said to be working on a new iPad Pro as well, however this device is unlikely to be announced this week.
Apple introduced new battery health charts for the iPhone in iOS 12. The battery Usage and Activity charts can be found in the Battery section of the Settings app. The new tools are an extension of the Battery Health tools introduced iOS 11.3. iPhone users can now see their last charge level, and battery usage by apps broken down by the last 24 hours and last 10 days.
With iOS 12, Apple encroaches on Snapchat's turf with a suite of new stickers and filters for the Messages camera, along with the ability to use Animoji and Memoji on FaceTime calls. While the Messages app has had stickers for some time now, they've been relegated to message threads; now you can paste them on photos you take with the app's camera, a feature that's been available on Snapchat for years and more recently on Instagram and Facebook.
Live Listen makes it possible to enhance sound using the iPhone or iPad microphone. The feature has been available for iPhone owners with Made for iPhone certified hearing aids for some time. With the launch of iOS 12, Apple has expanded Live Listen to work with AirPods as well.
