Towards the end of 2017, Apple's announcement that the battery's aging phones had slowed down the processor speed, that is, slowed down. After this explanation, while the users tried to learn the status of their phones by doing iPhone battery test , the iPhone battery health solution came from Apple.
Apple launched battery health with the 11.3 update released in March 2018. In this way, it is possible to learn the battery status of iPhone easily without any application .
To view iPhone battery health status, simply follow the path Settings> Battery> Battery Health . The Maximum Capacity section shows the status of the battery. In this section, we see that there is a 10 percent loss in battery capacity.
“ Highest Performance Adequacy ” indicates that battery health is sufficient to ensure the best performance of the device. If your battery life is below enough, you will see the text " Service " at the top, indicating that you will not be able to benefit from full performance.
The " Improved Battery Charge " at the bottom helps the phone to extend your battery life by learning your daily charging routine.
Of course, there are dozens of applications on the App Store under the name " Battery Life ". While these apps claim that the device displays battery health, reports battery status in detail , there was little need after iOS 11.3 .
