Less unused apps = less stuff to update = less stuff to backup = less stuff to break on your phone = life is better.
If you have all kinds of apps on your iPhone in various folders and subscreens, it might be hard to know what you have and what can be tossed. Here’s an easy way to remove the cruft.
From your main screen swipe left until you get to the last screen which is an automatic grouping Apple made for you.
Click that box at the top that says “App Library”
Up pops an alphabetized list of all your apps, no hiding. Simply long press on any icon to see the option to delete the app.
Rinse and repeat!
