Finally, if you’re still struggling with a slow iPhone after trying all of the other tricks we mentioned, you should try a Factory Reset. This is certainly not the most convenient tick, as it will reset your iPhone to factory defaults and delete all the data on your phone. So, just remember to back up all of your data before performing the reset and you’ll be good to go.
You can easily backup everything to iCloud, but if you don’t have enough space, you can connect it to another device and back it up there.
Here’s how to reset your iPhone:
- Open Settings.
- Tap General.
- Tap Transfer or Reset iPhone.
- Erase All Content and Settings.
