iOS 27 Update: Essential Tips Before You Upgrade Your iPhone 2026

iOS 27 update is officially rolling out today for all compatible iPhone models, and before you hit that install button, there are a few important things you should do to ensure a smooth upgrade. The new operating system will start arriving this afternoon, so it's wise to make some preparations now to avoid any hiccups.

We'll walk you through the key tips to consider before updating, then give you a step-by-step guide to the update process, and finally list the iPhone models that support iOS 27.

Why You Should Prepare Before Updating to iOS 27

Updating to a new version of iOS is generally safe, but it's always better to be prepared. A little prep work can save you from potential data loss or a stalled download. Here's what you need to know.

Back Up Your iPhone

Before you update, make sure to back up all your data. Whether you use iCloud, a Mac, or a PC, a backup ensures that if something goes wrong during the update and you need to restore your device, you won't lose your photos, messages, or app data.

It doesn't matter which method you choose—just make sure you have a recent backup before proceeding.

Free Up Storage Space

iOS updates typically require around 10 GB of free space, sometimes more. Having enough storage ensures the download completes quickly and without interruptions. Go to Settings > General > iPhone Storage to check your available space and delete any unnecessary files or apps.

Ensure a Stable Wi-Fi Connection

It's recommended to download the update over Wi-Fi to avoid using cellular data and to ensure a stable connection. A strong Wi-Fi signal will help prevent the download from failing or taking too long.

Charge Your iPhone

Make sure your iPhone is sufficiently charged, or better yet, plug it in during the update. The update process can take a while, and you don't want your battery to die in the middle of it.

Step-by-Step Guide to Updating to iOS 27

Once you've completed the preparations, follow these steps to update your iPhone:

• Back up your device using iCloud or a computer.
• Free up at least 10 GB of storage to accommodate the update.
• Connect to a stable Wi-Fi network and plug in your iPhone.
• Go to Settings > General > Software Update and tap "Download and Install."
• Wait for the download and installation to complete—your iPhone will restart automatically.

What to Watch for After the Update
