How to Fix Unable to Install Update on iPhone [Solved]

These days we are finding many reports that say several iPhone users are unable to install the update on their iPhones. This can be really frustrating since these iPhone users are missing out on the latest updates which could have software bug fixes or any other enhancement features on the iPhone.

The potential reason behind this issue might be a lack of storage space on the iPhone, technical glitches within the iPhone, network issues, poor internet connection, partially downloaded updates, low battery level, etc.

Having these factors in mind, we have figured out a few fixes after researching thoroughly and listing them in the article below. If you are also facing this issue, don’t worry. Just follow these fixes.

Initial Fix

  • Battery Level – It has been noticed that if the battery on any iPhone is lower than 40%-50%, it might restrict certain functions like installing an update, etc. So when your iPhone battery is low, please connect your iPhone to the charger and keep it charging until it crosses 50%.
  • Get a Stable and Strong Internet Connection – When the internet connection is unstable and poor, it creates problems while downloading and installing any update from Apple on your iPhone. So restart your Wi-Fi router once and see if this gets the improved signal strength. Otherwise, switch to the mobile data network.
  • Check Apple’s server status – Sometimes due to overloaded requests from millions of iPhone users to update their iPhones, this might cause their server to get shut down temporarily. So check the status of the Apple server and if you find it down, please wait for a few hours and try again later.
