Here are the major features in iOS 11.3:

Battery Health
Apple’s iOS 11.3 update brought a new feature to show battery health of an iPhone or iPad and recommended if the battery needs to be replaced. The new feature can be found in the Settings app, nested under “Battery,” called “Battery Health”. And the feature has been made available for iPhone 6 and later iPhones.

If you visit this on an iPhone with a battery Apple deems healthy, it shows the “maximum capacity” of your battery along with a link to the webpage for more details.

In addition, there is the new power management feature that dynamically manages maximum performance to prevent unexpected shutdowns. This is listed under section Peak Performance Capability.

If your phone has never experienced an unexpected shutdown due to low battery health, it will simply say: “Your battery is currently supporting normal peak performance.”

On iPhones with poor battery health, there is now an option to disable the performance-management feature. Users can turn off this feature as Apple promised, but there’s risk of unexpected shutdowns.

Notably, the feature isn’t visible unless your device has shut down unexpectedly and you can’t turn it on unless you have run into the problem. This feature is available for iPhone 6, iPhone 6 Plus, iPhone SE, iPhone 6s, iPhone 6s Plus, iPhone 7 and iPhone 7 Plus.
