What is iPhone Battery Health?

It is a feature that was added in iOS version 11.3 in the year 2018. To check this feature on your iPhone, you need to go to the ‘Settings’ menu and scroll down to ‘Battery Health’. This will provide you with basic and useful information about the performance and health of your iPhone’s battery.

With the help of this feature, you can keep an eye on your battery’s health and optimize the performance of your phone. Not only this, it will also give you an idea of when you need to replace your iPhone battery.

This shows battery health in three items or categories on the dashboard: Maximum Capacity, Peak Performance Capability, and a toggle to Optimise Battery Charging.

Maximum CapacityIt is the efficiency of your iPhone battery since it comes out of the manufacturing unit. A battery typically loses its efficiency over time. This explains why old phones have less healthy batteries. Optimal phone performance: between 100% and 80% 
Peak Performance CapabilityWhen you see a message on the dashboard saying that your phone is capable of peak performance, this indicates that your phone battery is working well and you don’t need to replace the battery yet. However, if you find “unable to deliver the necessary peak power” on the dashboard, then you need to replace the battery soon. 
Optimized Battery ChargingToggling this feature will restrict your phone charging to 80% to save the battery. This will also increase the overall life of your iPhone battery. It is an ideal option if you charge your phone overnight. It also turns this feature off when you are planning to travel so that you can charge your battery 100% before the travel.
