The easiest way to update your phone is by letting your device handle it. Following is how you can ensure that your phone has been automatically updated:

  • Open the Settings app

  • If they are not on already, tap them and turn them green so that your phone starts to update automatically

When you turn on this feature, your device starts getting updated while charging overnight.

There could be a number of reasons your phone fails to update. We have discussed some of the most common issues with the iOS update below.

  • Poor Internet connection: As we have already discussed, you need to have a strong and stable internet connection to update the latest iOS. When the Wi-Fi is not working properly, you will get the message saying, “Unable to Verify Update’. To deal with the issue, you can either sit closer to your wifi or go to a friend’s place to update your device.

Note: Close all the background activities while your phone is updating as it could affect the wifi’s speed.

  • Not enough space on the phone: Your phone must have some free space to install the new updates. For instance, IOS 14 required 3GB of free space to install, and the older versions required even more. Since IOS 15.4 is the latest update available, it will cost you just 1.25 GB to install.
  • Low Battery: To update your iPhone, you need to have a minimum of 50% battery. The installation will not start if the battery is below that. However, you can put your phone on charge during the installation to combat this issue.
  • Reset your phone and then update: If none of the above solutions works, consider resetting your device. Doing so will revert your phone back to its default settings. You retrieve your data from iCloud and then begin re-installing the update. Hopefully, this will resolve the issue for sure.
