Iphone: iPhone 15 models have a ‘new’ way of protecting batteries

Apple launched the iPhone 15 series at the Wonderlust event last week. The latest lineup includes four models — iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max. The iPhone 15 series comes with several improvements which include a replacement for the Lightning charging port. Apart from getting USB-C charging, the Cupertino-based tech giant has also added a new feature to the latest iPhonesthat will help protect the batteries of the smartphones.This setting was first discovered in iOS 17 code by software researcher Steve Moser.
iPhone 15 can restrict batteries from being fully charging
All the models in the iPhone 15 and iPhone 15 Pro lineup feature a new battery health setting. When enabled, this setting prevents the devices from charging beyond 80% at all times. The feature was first spotted by MacRumors. We at TOI-GadgetsNow were also able to access the option in the Charging Optimisation option available in the Battery section in Settings.

How is it different from the Optimised Battery Charging
The pre-existing Optimised Battey Charging feature on iPhones is different from the new setting. The older feature can intelligently delay charging past 80% until a more appropriate time. The feature learns from the user’s daily charging routine of the iPhone.

On the other hand, When the 80% hard limit feature is enabled, the iPhone will never charge past that point whatsoever. This feature is not available in the previous iPhone models and can be accessed only on the latest iPhone 15 models.

How to access the feature
All iPhone 15 devices have three options under Settings>Battery>Battery Health & Charging>Charging Optimisation:

Just like the Optimised Battery Charging option, the new feature also safeguard’s iPhone’s battery. However, the 80% hard limit can improve an iPhone battery’s lifespan by reducing the time that the battery is fully charged.
