To make your storage clean-up job even easier, it helps to know what apps or files are taking up the most space on your phone. This will differ from person to person. Perhaps you take a lot of photos and videos, or maybe you're a prolific texter. Whatever the case may be, find out which of your habits are using significant storage in just a few simple steps.
Start in the General section of your settings and tap 'iPhone Storage'. At the top, you’ll see a color-coded bar showing how much space you have left, how much is taken up, and which apps or files are using the most. You'll also see a ‘Recommendations’ header with suggestions from Apple on how to clear space. Following this will help you to clear the largest files so you can instantly free up storage quickly, easily, and efficiently so you can have more space for the things you really need. It really is that simple!
