Go to Settings > Photos & Camera and deselect My Photo Stream. This will delete your Photo Stream from your iPhone.
Unfortunately, it also means that your iPhone photos are no longer uploaded to your Photo Stream on your other devices. You can always turn it back on again after the storage issue has passed.
Step 7 of 19: Don't join other people's Photo Streams
You can create and share photo streams with other people. This is a nice way to share images of events you attended with friends, or pictures of grandchildren with grandparents, but beware that if you join someone else's photo stream it may quickly fill up your iPhone.
Make sure you have Photo Sharing turned off in Settings > Photos & Camera.
There is also the new iCloud Photo Library, currently in Beta. When this launches you will be able to automatically upload and store your entire librarin in iCloud to access photos and videos on all your devices. For now we don't know how much space these images will take up space on your iPhone.
Step 8 of 19: Don't keep both photos when using HDR
Your phone can use an HDR mode to capture better photos when the image would include bright lights and shadow. You can choose for your iPhone to keep the normal photo, which is handy if you have a slower iPhone - perhaps an iPhone 4, which can be a bit hit and miss with HDR mode due to the slower camera.
However, in newer iPhones we think HDR works well enough for you to be confident that the image you take will be better than it would be without HDR. So make sure that you aren't keeping the normal photo - go to Settings > Photos & Camera and deselect Keep Normal Photo.
Step 9 of 19: Sign up for iTunes Match
You don't have to have every iTunes track you could ever possibly need to listen to on your iPhone. If you sign up for iTunes Match (for £21.99 a year) you will have every track you own available to you via the cloud. Therefore you can delete your music from your iPhone knowing that every song you may wish to listen to is but a download away.
Once you have signed up for Apple's service, all your music on all your Apple devices will be uploaded to iCloud (even tracks you have imported from CD). This means that you can download any track you fancy listening to on your iPhone whenever the mood takes you.
You can download a track or a whole album, or a whole playlist. Just click on the iCloud download icon. If you then want to delete the track from your iPhone, just swipe left on it, to delete. It will still be available to download from iCloud another time.
