Apple announced on Wednesday the next big iOS update that will soon be available for iPhone, iPad and iPod touch, iOS 11.3, and then released the first beta version for developers: a public beta should also be available soon.  iOS 11.3 will bring several interesting features, such as iCloud Messages, Health Records, support for better AR experiences, more Animoji, but also new battery management options that will be useful, especially on older devices. Some of these features are already available in the first beta version, and you can now try them on your iOS devices.
Health Records has to be one of the most impressive additions to the Health app, which will offer people a better way to manage their health, beyond tracking fitness activities. As you can see in the following video from MacRumors Health Records should offer a fairly uniform way of adding medical records from various sources.
iCloud Messages is not exactly a new feature. It has been introduced as a key feature of iOS 11 last June, but Apple could not offer users a finished product yet. iOS 11.3 should finally enable the feature, which will help you free up additional space on your iPhone, keeping iMessage content in the cloud instead of on the device.
Battery health management is the future that we are most curious to see in action, taking into account the current iPhone slowdown controversy. But it is not available in iOS 11.3 beta 1.
The following video shows everything new in iOS 11.3, since Apple has other minor adjustments in mind for its iPhone experience:
