How To Download the Update Again
If your iPhone or iPad is having problems after installing iOS 17.3, try deleting the update and downloading it again:
Step#1.Open the Settings app and tap General.
Step#2.Tap Software Update.
Step#3.Tap Delete Update. Confirm by tapping Delete Update again.

Downloading the update again can help eliminate any errors or glitches from the initial download and installation. Make sure you have a stable Wi-Fi connection before downloading again.
How TO Update with iTunes
If re-downloading the update directly on your iOS device doesn’t fix the issues, try updating using iTunes on your computer instead.
Step#1.Connect your iPhone or iPad to your computer using the USB cable.
Step#2.Open iTunes. Make sure you have the latest version.
Step#3.Select your device in iTunes.
Step#4.Click Summary > Check for Update

Updating via iTunes performs a “clean” install of the software, which can fix many common problems. iTunes also gives more verbose error messages, which can help diagnose any issues.
How To Restart Your Device
One of the simplest fixes for any iOS issues is to restart your device:
Step#1.On an iPhone 8 or later, press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Finally, press and hold the Side button until you see the Apple logo.
Step#2.On an iPhone 7 or earlier, press and hold the Sleep/Wake button until you see the “slide to power off” prompt. Drag the slider to turn off your phone. To turn it back on, hold the Sleep/Wake button again until you see the Apple logo.
Step#3.On an iPad, press and hold the Top button until the “slide to power off” prompt appears. Drag the slider to turn your iPad off. To turn it back on, hold the Top button again until you see the Apple logo.

How To Reset Network Settings

Step#1.Go to Settings > General > Reset.
Step#2.Tap Reset Network Settings.
Step#3.Enter your passcode if prompted.

How To Check Device Compatibility
It is possible your iPhone or iPad model is simply not fully compatible with iOS 17.3. Very old models in particular may experience significant issues running the latest iOS.
Check Apple’s iOS 17.3 compatibility page to see if your device is supported:
If your device is not listed as compatible, you may need to either live with the issues or consider upgrading your hardware to a newer iPhone or iPad model that can properly run iOS 17.3.
How To Free Up Storage Space
If your iPhone or iPad is almost out of free storage space, it may exhibit stability issues and crashes after updating to iOS 17.3.
Try freeing up more space:
- Offload unused apps
- Delete old messages, especially from iMessage
- Move photos/videos to cloud storage or computer
- Delete unused music, books or podcasts
Having at least 5GB – 10GB of available storage allows iOS to run smoothly. iOS can slow down and encounter errors without enough free space.
How To Ensure Stable Internet Connection
Download and installation issues are often caused by a poor or unstable internet connection. If you are installing an iOS update over cellular data, switch to a stable Wi-Fi network. Avoid public Wi-Fi hotspots, as they can drop connection during the install.
For the best results, use your home Wi-Fi network with strong signal strength. Disconnect any other devices using the network to maximize bandwidth. Moving closer to your wireless router can also improve signal reliability.
A stable, fast internet connection ensures complete download of the iOS update package and avoids any installation errors.
How To Check Battery Health
If your iPhone or iPad battery is worn out or damaged, updating to iOS 17.3 may trigger new battery-related problems.
To check your battery health:
- Go to Settings > Battery > Battery Health.
- The Maximum Capacity reading shows your battery’s overall condition. Anything under 80% may indicate a worn out battery.
You can also watch for telltale battery issues like your device powering off unexpectedly or needing frequent charging.
If you suspect your battery is failing, replacing the battery before updating can reduce potential issues. See Apple’s battery service options:
