5 common iPhone issues and how to fix them

1

iPhone battery won't charge

After a failed charge, we recommend you ensure your USB power adaptor is plugged in all the way and your power outlet is working. If this still fails, try a different USB cable, USB power adaptor or USB port. Thirdly, unplug your iPhone and check the connector port, ensuring it is free from any debris - (you can do so with a cotton wool bud or clean paintbrush). If everything seems to be working, plug in your iPhone again – waiting 30 minutes. Finally, if this still fails, restart your device while it is connected to the power source (for a full re-boot guide, please scroll down to number 3).


If you receive one of these alerts “This cable or accessory is not certified and may not work reliably with this iPhone” or “This accessory is not supported by this device” - we recommend you purchase an Apple-certified accessory.

No service

Firstly, ensure your mobile data is switched on. You can do so by heading to Settings > Mobile. While your there, make sure your iPhone’s Carrier Settings are up to date by going to Settings > General > About. If there’s an update available, you will prompted at this point. 


If you are still unable to get service, we recommend you re-start your iPhone and remove your SIM card to check for any physical damage. If you cannot see any damage, reinsert your SIM card and re-boot your iPhone to see if it works (for a full re-boot guide, please scroll down to number 3).

Crashing applications

For crashing applications, try re-setting your iPhone. To do so hold your home button (the circular button in the bottom centre of your iPhone, below your screen) and the sleep/wake button (on the top edge of your iPhone, on the right-hand side) simultaneously. Continue holding both buttons until your iPhone shuts down and begins to restart – this can take anywhere between 10-20 seconds. Let go of both buttons when you see a silver Apple logo on your screen – this means your iPhone is re-booting, and the reset has completed successfully. Please note: this process differs for the iPhone 7/7 Plus, iPhone 8/8 Plus and iPhone X - click here for the guide.


If this fails, we recommend you tap and hold the offending app until it goes ‘wobbly’, hit X and delete the app, then head over to the app store and re-install the application. You can also conduct another reset after this step. Then, try your app!

Low storage capacity 

Taken a snap and received a ‘Not enough storage available‘ message? We recommend you check your iCloud storage before deleting any data (iCloud is an online storage programme available to all Apple users). To do so, head to Settings > iCloud > Storage > Manage Storage, and for earlier versions of iOS, head to Settings > iCloud > Storage & Backup. You have an initial 5GB free, and once that’s used, you can purchase more space for the following amounts:


50 GB: £0.79
200 GB: £2.49
1 TB: £6.99


This space can be used to back up your photos, calendar events, documents, notes and more without having to delete anything from your iPhone. To add more space to your plan, go to Settings > iCloud > Storage > Change Storage Plan, and select your desired amount – this will be automatically deducted from the card listed on your iTunes account.

Unresponsive or 'frozen screen'

Firstly, we recommend switching your iPhone on and off. If this fails a reset may be necessary. To do so hold your home button (the circular button in the bottom centre of your iPhone, below your screen) and the sleep/wake button (on the top edge of your iPhone, on the right-hand side) simultaneously. Continue holding both buttons until your iPhone shuts down and begins to restart – this can take anywhere between 10-20 seconds. Let go of both buttons when you see a silver Apple logo on your screen – this means your iPhone is re-booting, and the reset has completed successfully. Please note: this process differs for the iPhone 7/7 Plus, iPhone 8/8 Plus and iPhone X - click here for the guide.
