So, with that said, here’s how to fix a frozen iPhone in a matter of minutes, and how to restart earlier models.
Why is my iPhone frozen?
It’s a question we all hate to ask, but wondering why your iPhone is frozen is the first step to finding a solution. Getting a slow smartphone sorted is always a top priority, as it impacts productivity and efficiency.
So, it’s no surprise that you want to get it operational ASAP. Scroll down and find out both the root causes and how to fix them.

Whilst we hope your phone is never physically frozen, there are a few lesser-known reasons why your iPhone is frozen, such as:
Potential Causes
Even the newest iPhones running the latest iOS aren’t immune to occasional glitches. Here are the most common reasons:
- Software bugs – a misbehaving app or background process can cause a lock-up (read about the new iOS 26 features)
- Outdated iOS – running old software may trigger compatibility issues.
- Low storage – iPhones with little free space often lag or freeze.
- Overheating – heavy use or hot environments may cause iOS to slow down or freeze.
- Hardware problems – damaged screens or faulty batteries can sometimes lead to freezing.
- Low storage
- A clogged cache
Quick Tips:
As mentioned, we recommend updating all of your apps beforehand. You should also check to see if your storage is nearly full, before backing up or deleting any large files.
We also recommend turning off automatic updates via your smartphone settings, if necessary.
Sometimes, simplicity is best; if you have tried to turn it off and it isn’t working, then try forcing it to restart. In most cases, you’ll be able to reboot it and fix your frozen iPhone by following the easy 3 steps process below.
Step-By-Step: How to Fix a Frozen iPhone
So, with all those reasons WHY your iPhone is frozen, here are several steps on how to fix it. Please note, these instructions will vary depending on the model.
Warm up with a quick video from Simply Mobile and familiarise yourself with the process:
1. Force Restart
As outlined above, this is always the first step. It won’t delete your data and often clears temporary glitches.
2. Charge Your iPhone
If your iPhone is frozen and won’t turn back on, plug it into a charger for at least 15 minutes. A completely drained battery can look like a frozen phone.
3. Update iOS
Go to Settings > General > Software Update and install the latest iOS. Apple regularly releases fixes for freezing and unresponsive screens.
4. Free Up Storage
Head to Settings > General > iPhone Storage. Delete unused apps, photos, or large files. Consider moving media to iCloud.
5. Close or Delete Problem Apps
If the freeze started after opening a specific app, restart and then remove it. You can reinstall later once updates are available.
6. Reset All Settings
If freezes continue, go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This won’t erase your photos or data, but will restore Wi-Fi passwords, wallpaper and preferences.
7. Restore in Finder/iTunes
If nothing else works, you may need to restore your iPhone using a computer.
- Connect to your Mac (Finder) or Windows PC (iTunes).
- Select your iPhone.
- Choose Restore iPhone.
⚠️ This erases everything, so back up first.
8. DFU Restore (Advanced)
If your iPhone is still frozen after a restore, try a DFU (Device Firmware Update) restore. This reloads both iOS and the firmware. It’s a last resort and best done with Apple’s own support guidance.
Preventing Future Freezes
The easiest way to fix your frozen iPhone is preventing it from happening in the first place! Here’s how:
- Keep iOS updated.
- Regularly clear storage.
- Avoid beta or poorly rated apps that can cause instability.
- Don’t let your iPhone overheat – keep it out of direct sunlight or hot cars.
- Restart your phone occasionally to clear background processes.
