The long-awaited launch of a new operating system called iOS 14.5.1 and iPadOS 14.5.1 by the American corporation Apple took place on May 3, 2021. Despite the fact that it is planned that the majority of users will switch to the new operating system in the first year after the release, Apple notes, that already 81% of users who own the last four iPhone versions have successfully updated the operating system and are enjoying its full benefits.
In fact, not all users of Apple Corporation devices of already outdated versions are in a hurry to make the transition to a new operating system, which is associated with a possible loss of autonomy of a mobile device. To understand the concerns of some iPhone users, the authors of the YouTube channel iAppleBytes decided to compare the autonomy of seven generations of the iPhone, updating the operating system to iOS 14. To test the capabilities of the new iOS, they took the phones of the American corporation, ranging from the iPhone SE to the iPhone 11.
