What is the iPhone battery health tool? How to monitor your device’s performance

Apple Admits To Slowing Phones Down As Their Batteries Age

A few months ago, Apple admitted to slowing down iPhones as batteries age to prevent unexpected shutdowns. Now, the company is introducing a new battery management system in its iOS 11.3 beta 2 to help users better preserve their devices.

The feature, only available to iPhones 6 and later, helps users monitor and predict the battery’s performance and health. Located in the settings tab under “Battery,” it reveals the maximum capacity and peak performance capability of the phone.

While the maximum capacity measures the battery’s full charge ability compared to when it was new, the peak performance capability reveals how the battery’s degradation is affecting the phone’s peak execution.

In December, Apple issued an apology over the iPhone battery speed, saying there has been "a lot of misunderstanding" about the issue.

“We have never — and would never — do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades. Our goal has always been to create products that our customers love, and making iPhones last as long as possible is an important part of that,” it said.

Instead, the corporation said the goal was to prevent unexpected shutdowns as the battery life inevitably fades over time.

Amid the backlash, some customers sued and Apple later offered discounts for battery replacements. Now, with the new battery management tool, which can be disabled, users will have more information regarding their phone's overall health.
