Automatically Install iOS Software Update in the Middle of the Night | OS X Daily
Those of you who run an Apple mobile device i.e. the iPhone, iPad or iPod Touch will end up keeping iOS which is the device’s operating software updated. But you may find that the software update will have your device out of action while it is downloading or installing.
Why can’t this be possible for that iPhone to be updated to the latest iOS version while I am asleep? You can achieve this goal.
What does your iOS device need?
Backing up device data
You need to back up your iOS device’s data, preferably to the iCloud incase something goes awry during an update such as a bad download. Here, you cam manually backup the device to iCloud over-the-air or to iTunes on your regular computer. Or you can set up iCloud to automatically backup your iOS device every night.
The backup will save your device’s app list, local data held by your apps, user credentials associated with online services where you use a native-client app, your email setup details and, most importantly, your Camera Roll.
Setting up your device
Your iOS device needs to be connected to an AC power source as if for charging. You may think that you may get away with an external battery pack but you are never sure if they are in a position to last the distance, so it is a better idea to stick with an AC charger.
As well, your would have to connect your iOS device to your Wi-Fi network. If you are dealing with a public-access network that implements Web-based login like the one in your university’s residence hall / dorm or your favourite hotel or B&B, make sure your iOS device is logged in to that network with the “login-confirmed” page kept open in Safari. With these networks, you could enable both the “Auto-Join” and “Auto-Login” functions so that you stay logged in on the networks.
Similarly, if you make a habit of shutting the Wi-Fi or Internet off overnight, either to save money or protect yourself from perceived radiation dangers, you would need to keep the Wi-FI and Internet on to facilitate this update.
Start overnight updating
When you see the “Software Update” reminder screen pop up, select the “Later” option.
This will offer you an option to remind you later or install the update tonight. Select the latter option for overnight installation to commence.
Your iOS device will commence downloading the latest version of the iOS operating software at a time between 2am and 5am and then deploy that software. This will involve the iOS device power-cycling so as to fully “cement” the new operating software.
