iOS 9 allows the automatic installation of software updates, Apple employees explaining during this day the way in which the operating system for iDevices, as well as OS X El Capitan they will install the latest updates.
In the attached image you have a demonstration of how the alert from iOS 9 will look that will allow us to select the later installation of a software update, OTA UPDATE, the Install Later option being the one that performs the installation at a later date.
In OS X El Capitan, users will have the option to have the installation done during the night, the Apple company choosing a period between 02:00 and 05:00 to automatically install the updates, assuming that then users are not using their Mac- the hours.
Although in iOS 9 there are no details regarding the automatic software update mechanism and no similar options, it seems that the idea will be similar, with iOS automatically updating itself over night, if the user does not use his terminal then.
We're also changing the way software updates are presented to the user. Users will be given a choice to install right now, or later at night when they might not need access to devices. So we think this is going to keep pushing users to update quickly, and will allow you to keep focusing your energies on the latest version of iOS.
Users will have to manually select the automatic installation option at a later date, and if then the update for iOS 9 or OS X El Capitan cannot be done, then a new alert message will be displayed to repeat the process.
Apple has big problems in convincing users to install iOS 8, the adoption rate being lower than in the case of iOS 7, so this automatic update method was designed with the idea of constantly reminding users to install their software updates.
Combining the system with the fact that iOS 9 will have a size of only 1.3 GB for software update, OTA Update, instead of 4.6 GB as requested by iOS 8, we have as a result a possible high adoption rate for iOS 9.
