What is important to know

Apple regularly releases updates with bug fixes and improvements, and once a year big iOS updates with new features. They are quite simple to install both from the device itself “over the air” and using a computer.

At the same time, starting with iOS 14.5, it is possible to choose whether to stay on the current firmware and receive only important security updates, or switch to the current version in order to have the latest software on the device.

This is quite useful because, despite the fact that older iPhones and iPads support modern versions of iOS, experience shows that installing them is not a good idea. This results in a drop in performance and battery life, so think twice and look at the reviews of other users, for example by looking at reviews on YouTube.

When installing an over-the-air update, downloading firmware files requires a certain amount of free space, and if it is not enough, iOS may offer to automatically remove bulky applications. Do not worry and agree – after the update, all information will be reloaded. If there are still few resources, try to free the storage yourself.

1. How to update iPhone automatically

If you have a current model or an iPhone 2-3 years old, then the easiest way is not to bother and use the auto-update function. In this case, when a new version of iOS is released, the smartphone will automatically download and install it at night, provided it is connected to charging and Wi-Fi.

To provide such a scenario, open Settings and go to General → Software Update.

Tap on “Auto Update” and make sure the toggle switches for “Download iOS updates” and “Install iOS updates” are turned on.

2. How to update iPhone manually “over the air”

Also a very simple way. Make sure your iPhone is at least 50% charged and has a stable internet connection via Wi-Fi or cellular.

Go to “Settings” and tap on the item “Software update available” or open the section “General” → “Software update”.

Select “Download and Install” to get a fresh version of your current OS version, or “Upgrade to iOS 20” to upgrade to the next firmware version. Enter your passcode.

Next, confirm the installation by agreeing to the terms of use and wait for the process to finish.

3. How to update iPhone manually using a computer

To update this way, you need a Mac or Windows computer with iTunes, as well as an iPhone connection cable. This option is useful in case of errors when downloading “over the air” or when there is not enough memory on the smartphone.

Connect iPhone to your computer with a cable, and then open Finder (on macOS Catalina and later) or iTunes (on earlier versions of macOS or on a Windows PC).

Select your iPhone in the sidebar and click Update.

Then – “Download and update”.

After that, agree to the terms of use by clicking “Accept”. Enter the passcode on the screen of your mobile device and wait for the update to download and install.
