Disable 'double saving' of pictures
When you take pictures on an iPhone using the HDR mode, you’ll see that your phone will save 2 copies of such pictures – a normal photo and another HDR photo. This occupies twice as much space. If you take a lot of HDR pictures, this is going to become a very visible problem.
To fix this, go to Settings > Photos & Camera. Scroll through to the end of the options and turn off the toggle against “Keep Normal Photo”.
Remove unused apps
Unused apps are a big-time storage occupier and linger on for months without you even realizing. If you have unused games, they’re going to take up even more storage.
If you don’t plan on using the app or game for the foreseeable future, delete them.
If you feel you might use the app again – offload the app. Offloading an app means that you’ll still see the app on your home screen, but you’ll need to tap on it and reinstall it before you can use it.
If you want to automate the offloading process, go to Settings > General > iPhone Storage > Offload Unused Apps and enable it.
Get rid of old music
If you love hooking up your AirPods while you commute to work, you probably have a healthy playlist on your phone. Over time, it can occupy a good deal of space on. If you’re looking to free up space, getting rid of unused tracks will help you free up considerable space.
If you use Apple music, deleting these tracks is pretty simple. Go to Settings > General > Storage & iCloud Usage > Manage Storage and look for “Apple Music”. It will allow you to delete songs individually, or if you want trash all of it there’s an option to delete all songs at once at the top.
