iPhone 15 users can check the health of their battery at a glance after updating to iOS 17.4،
According to an update on a support page, Apple is making a change to the Battery Health section of the iPhone Settings app, but only for iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max and only once on iOS. 17.4 is installed. This small change, available only on the aforementioned models, will allow users to have an overview of the health of their iPhone's battery at a glance. Once your iPhone15 the production model has been updated to iOS 17.4, you will be able to open the Battery section and see a quick readout of your battery status.
For example, go to Settings > Battery and next to the words “Battery Health” on the page you can see “Normal” giving you a quick overview of the health of your battery without having to press the Battery Health & Charging button on which you previously had to press. If you press the Battery Status button on a iPhone15 series phone, you will see the date the battery was manufactured, the date the cell was first used, the number of battery cycles and the maximum capacity.
New look for the Battery section of the Settings app on iPhone 15 series models running iOS 17.4
The maximum capacity figure compares the battery's current capacity to when the cell was new. The result is a percentage reading that could indicate that your battery has a maximum capacity that matches the capacity when the phone was originally purchased (100%). A lower reading indicates that the battery is degraded. If the percentage drops below 80%, Apple suggests replacing the battery.
With iOS 17.4, Apple makes a change to the Battery Health section of the iPhone Settings app on the iPhone 15 lineup
The Battery Health section of the Settings app was added to iPhone in the wake of #Batterygate. Older iPhone models would shut down when performing complex tasks because weaker batteries couldn't power the processor to handle those tasks. Apple unilaterally decided to include a method in the iOS 10.2.1 update that allowed it to limit these older iPhone models without iPhone users knowing. Lawsuits followed (see what we did there?) and it wasn't until this January that affected iPhone users began receiving their share of the $500 million settlement.
When Tim Cook apologized for #Batterygate in late 2017, he offered iPhone users a special deal allowing them to change weakened batteries for just $29. And with iOS 11.3 in 2018, Apple sent iPhone users the first “Battery Health” page. This is a welcome addition as it allows iPhone users to quickly know their battery and whether it needs to be replaced.
