Apple today released iOS 11.3, the twelfth official update to the iOS 11 operating system that first came out in September of 2017. iOS 11.3 comes more than a month the launch of iOS 11.2.6, a minor update that fixed a bug causing crashes due to the incorrect rendering of a character in the Indian language Telugu.
The new version has a slew of additions, including new Animoji characters for the iPhone X, improved ARKit for more advanced augmented reality, and the ability to turn off processor throttling for iPhones with aging batteries inside.
With today’s update, iOS will show the battery health of an iPhone and recommend if it needs to be serviced — this applies to iPhone 6 and later. Plus, users are now able to turn off the management feature that reduces an iPhone’s processing power — this applies to iPhone 6, 6 Plus, SE, 6s, 6s Plus, 7 and 7 Plus.
IOS 11.3 updates the iPhone’s AR functions, allowing apps to read vertical surfaces like walls and doors, and irregular objects like chairs or circular tables. There are also a handful of new Animoji available today: lion, bear, dragon and skull.
Also new is a Health Records section inside the Health app, giving patients quick access to their medical records (from supported doctors and care centers) directly on their iPhone.
Continuing its strong stance on security and privacy, iOS 11.3 (and macOS 10.13.14) include a new privacy icon that shows up whenever Apple is asking for your personal information — such as your Apple ID password — so that you can easily verify that the request is legitimate and not spoofed.
The release of iOS 11.3 includes support for Business Chat in the U.S., which will let you interface with businesses like Wells Fargo, Delta, Hilton and Lowe’s right in the Messages app. Improvements have been made to security in Safari, Handoff and Universal Clipboard have been improved, there are new Accessibility features, and bug fixes for keyboards.
