There are a number of different reasons why your iPhone might be freezing, each with different fixes, so if you’re unsure as to what’s causing it then it’s worth try a few different solutions to narrow down the problem.
Firstly, if your iPhone is frozen you’ll want to get it functioning again ASAP. You can do this by performing a force restart. The process required to do this is slightly different on each model:
- On an iPhone X, iPhone 8 or iPhone 8+, quickly press and release the volume up button, followed by the volume down button, then press and hold the side button until you see the Apple logo on screen.
- On an iPhone 7 or 7+ press and hold the volume down button and the side button at the same time for around 10 seconds until you see the Apple logo on screen.
- On an iPhone 6s or earlier, press and hold the home button and the top button at the same tome for around 10 seconds until you see the Apple logo on screen.
This will restart your iPhone and get you back up and running, but how can you avoid freezes and crashes in the future?
Avoid extreme temperatures
iPhone’s are designed to work in the temperature range of between 0 and 35°C, and so both freezing temperatures and excessive heat can cause drops in performance. Being left out in the sun or being used in direct sunlight can cause an iPhone to overheat to the point of being to hot to hold, and sometimes an iPhone will shut itself down until it has cooled down sufficiently. Likewise, being too cold can limit performance too, with touchscreens becoming unresponsive and processing times slow.
Fast changes in temperature can cause condensation, which if it occurs within the phone can lead to extensive water damage. Because of this, it is very important to never try to fix overheating by using a fridge or something similar to cooldown your iPhone.
Clear your storage
As your iPhone (or any computer) reaches the limit of it’s storage capacity, it’s functions will start to slow down and sometimes potentially freeze. If you only have a small amount of space left, it’s worth clearing some of it out to see if this helps to improve performance. If you head to settings->general->storage & iCloud->manage storage, you’ll be able to see a breakdown of how much storage you’re using for different apps, photos, videos etc. A good rule of thumb is to leave around 250mb free, so if you have less than this available, then it’s worth backing up your photos and videos onto another device to clear some space on your phone.
Update your software
Apple release updates to their iOS software on a fairly regular basis, many of which come with fixes to known bugs and could well have a fix for your problem. To check if your software version is up to date, go to settings->general->software update. On this screen your iPhone will check for any available updates to it’s iOS, and if there are any then a download and install button will appear. Tap this and follow the instructions and see if the updated software improves your phone’s performance.
If none of these steps help to reduce freezes, then you may have to try restoring your phone. First back-up your phone either through iTunes when connected to a Mac or PC, or by using iCloud in settings. Then head to settings->general->reset->erase all content and settings. You will then be asked to enter your passcode and can then press the button Erase iPhone. Pressing this will reset all settings, and remove all of the media and data stored on your phone. When your iPhone finishes this process it will start up again as if new, and you can follow the initial set up again. During this process you will be asked if you want to restore your iPhone from an iCloud backup. Use this feature to restore your data, media and apps.
