On iOS 14.5, Apple has added a battery capacity re-measurement feature to the iPhone 11 series, helping the device measure the maximum battery capacity more accurately, overcoming unwanted battery drain. In some cases, re-measured results even allow a free battery replacement.

However, iPhone users with iOS 14.6 are still constantly reporting battery drain even though this version has been released for more than a week. Currently, Apple has not yet responded to the battery drain on iOS 14.6. The company is testing iOS 14.7 with some improvements, but may release iOS 14.6.1 if it finds the cause of the battery drain and needs to be fixed soon. Users can restore factory settings to check if the device is still draining the battery. Why does Apple name Apple Watch instead of iWatch? Apple has many products such as iMac, iPod, iPhone, iPad. However, when it came to smartwatches, they broke the rules and named this product line Apple Watch.
