Apple Seeds iOS 11.3 Battery Health (Beta)
The new battery health and performance management features are iPhone-only and available in Settings → Battery → Battery Health (Beta).
Off by default, performance smoothing kicks in once your iPhone starts experiencing unexpected shutdowns due to an excessive draw on its worn-out battery. You can turn this off by tapping a tiny Disable button to keep your iPhone operating at full speed, but at the risk of unexpectedly shutting down and reducing your battery lifespan.
Apple outlined how this works in a support document on its website:
Users can see if the performance management feature that dynamically manages maximum performance to prevent unexpected shutdowns is on and can choose to turn it off.
This feature is enabled only after an unexpected shutdown first occurs on a device with a battery that has diminished ability to deliver maximum instantaneous power. This feature applies to iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, and iPhone 7 Plus.
Aside from battery health assessment on iPhone, iOS 11.3 also includes a new iPad charge management feature designed to prolong battery health on Apple tablets that are connected to power for long periods of time.
Here’s everything new, fixed and improved in the iOS 11.3 software:
iPhone Battery Health (Beta)
- Displays information on iPhone maximum battery capacity and peak performance capability
- Indicates if the performance management feature that dynamically manages maximum performance to prevent unexpected shutdowns is on and includes the option to disable it
- Recommends if a battery needs to be replaced
iPad charge management
- Maintains battery health when iPad is connected to power for prolonged periods of time, such as when it is used in kiosks, point of sale systems or stored in charging carts
