Most people should install the iOS 15.4.1 update from Apple, and there are some steps to take before moving your iPhone from iOS 14 to iOS 15 or your current version of iOS 15 to iOS 15.4.1.
Apple has pushed a new iOS 15.4.1 update to iPhone users and it is now available for download. The software brings a new security patch and essential bug fixes for iPhone users.
If your iPhone is currently running iOS 15.4, you will get the shortest change log and smallest download. If you are moving from an older version of iOS, your iOS 15.4.1 update will be more significant. That’s because the changes from the iOS updates that you skipped are incorporated into your upgrade.
iOS 15.4.1 is a major upgrade and most iPhone users should install the software in the near future. That said, it’s hard to predict how Apple’s new software will affect your iPhone’s performance.
While some of you might see an improvement in your iPhone’s performance, others will encounter frustrating bugs and performance issues. And that’s why it’s important to do some prep work before starting the installation. A little work ahead of time can help you avoid serious problems.
If you notice any bugs or performance on iOS 15.4.1, keep in mind that you cannot downgrade your iPhone’s software. Apple recently stopped signing on iOS 15.4. It also doesn’t sign on anything older than iOS 15.4.
So if you have a good experience with iOS 15.4, iOS 15.3.1 or older software, moving your phone to iOS 15.4.1 is a big problem. Once you’ve taken the step, there’s no going back.
With that in mind, we want to help you prepare for the transition from iOS 14 to iOS 15 or your current version from iOS 15 to iOS 15.4.1. This guide will walk you step by step through the process we use before tapping install.
Back up your data
This step is extremely important. If you don’t have a lot of time to spend on the pre-installation process, make sure you do it.
Many of you already know how to properly backup your iPhone’s data (photos, videos, etc.), but if you’re not sure, we’ve got you covered.
Some of you will want to back up with Apple’s iCloud service. It’s an easy way to make sure your important files are safe. If you are not familiar with the iCloud backup process, give it a try Apple’s Guide†
If you don’t want to use iCloud, you can back up your files using iTunes. If you’re using macOS Monterey, macOS Big Sur, or macOS Catalina, you should be using Finder, not iTunes.
If you store a lot of data on your iPhone, it may take a while for the backup process to complete, so be patient.
Data loss issues are quite rare, but don’t take any chances.
