iOS 11 requires preparation iPhone and iPad for installing the update that will be offered for the operating system of the Apple company starting this evening. I have already told you when iOS 11 is released and you know what time to expect it, but before that it is good to know how to prepare your phones to properly install the update without risking compromising your data.
iOS 11 is a major update that the Apple company will offer for iPhone and iPad starting today, it being one of the most important released in recent years by the Americans. Here's what you need to do to prepare for the release of iOS 11, all starting from the idea that you checked beforehand iOS 11 compatibility with iPhone and iPad.
Backup, backup, backup, with iCloud or iTunes
iOS 11 must NOT be installed in the iPhone or iPad, without first making a backup using iCloud or iTunes, to be sure that you do not lose data in case of problems. In the past there have been various issues with iOS updates that locked up the iPhone or iPad during installation and required a restore to complete the process, so a backup can save you a lot of headaches.
iOS 11 can be installed without problems if you first make a backup via iCloud from Settings > iCloud > Backup, Configurations > iCloud > Backup. There you also have options for what you want to be saved in that backup, you can choose what you are interested in saving, so you will also know what you will be able to find in the phones in case you have to use the backup if the installation procedure of iOS 11 fails.
To install iOS 11, you can back up the data from your phones and through iTunes, but first you have to connect your iPhone or iPad to the computer. After that, click on the icon of your iDevice in the upper part of iTunes, and in the central menu you will have the option to make a local backup in the computer, or directly in iCloud, any of the options being good if you encounter problems when installing iOS 11.
iOS 11 could force you to delete all data from your iPhone or iPad, so apart from the backup, I recommend you to save your photos and videos on a computer, because if you don't use iCloud Photo Library, then they they will be deleted in case of restoration.
Free up space on your iPhone or iPad
iOS 11 requires up to 2-3 GB of free space for installation on iPhone and iPad, so make sure you have it on your iDevices. On the iPhone 7 Plus, iOS 11 required a minimum of 2 GB of space to install, but in the case of other iPhone models, especially those with smaller screens, the amount of space required for installation will be less, but it will not I can say exactly how many hundreds of MB.
iOS 11 for iPad Pro 12.9 inch might need 3 GB of space, or even more, to install, so it's good to have it available. If you do not have free space available on your iPhone or iPad, then the installation of iOS 11 will not take place, as the operating system may recommend the temporary deletion of some applications to perform the installation, they are automatically installed after the process is completed.
A good internet connection
Installing iOS 11 will require downloading a large file, at least 1 GB for your iPhone or iPad, so make sure you have a good internet connection. Whether we're talking about Wi-Fi or LAN, that is, if you're updating via iPhone and iPad, or computer, make sure you have enough bandwidth to download the update to iOS 11.
Minimum 50% battery, or a power source
iOS 11 will not be installed if you don't have at least 50% of the available battery on your iPhone or iPad, the Apple company implementing this restriction so that the process is not interrupted due to lack of energy and the products remain blocked. If you have a low battery, but a power source at hand, you can connect your iPhone or iPad to a charger, and the installation of iOS 11 will begin without problems.
Patience, patience and more patience
iOS 11 is awaited by extremely many iPhone or iPad users, and everyone will rush to install it as soon as the update appears. In this idea, it is possible that iOS 11 is very difficult to download from Apple's servers, so you have to be patient, the installation itself can take up to 15 minutes depending on the type of iDevice you have.
