Apple unveils battery-saving function in iOS 11.3

Apple Inc. said on Wednesday that the upgrade of its operating system, scheduled for the spring, will bring improvements in augmented reality (AR) possibilities for developers and a feature to measure battery health and save power.

The iPhone maker has sparked controversy after acknowledging its updates for older models impact performances. The new function in a later release will enable users to turn off the dynamic power management.

The AR experience will be enhanced with the positioning of two-dimensional images and the recognition and manipulation of virtual items on vertical surfaces, the company added. It said it has designed animojis with dozens facial expressions and prepared karaoke videos for them. Messages will be expanded with a business chatting platform, while patients will be able to access medical records from hospitals and clinics, according to the statement.
