By default, your iPhone stores all the text messages you send and receive forever. This is convenient if you need to search for a conversation, that occurred 1 year ago; not so convenient if you need storage space on your phone.

• To stop saving texts forever, open the Settings app and select Messages. Scroll down until you find Message History and select Keep Messages. Change the option to Forever, 30 days, or 1 year. A new window will ask if you want to delete older messages; press Delete to continue.
• NB! Selecting 30 days will delete all text messages older than 30 days and selecting 1 year will delete messages older than a year.

In addition to deleting apps, it is also possible to offload unused apps. The app is deleted but all data related to the app remains. This way, you can later download the app again and continue using it from where you left off the last time.

Offload unused apps:

1. Settings > iTunes & App Stores
2. At the very bottom you will find the line "Offload Unused Apps", which must be highlighted in green. Unused apps are downloaded automatically.

Manual offloading:

1. Settings > General > iPhone Storage
2. Choose an application that takes up a lot of space and click "Offload App".

Songs take up a lot of space on your phone, and if you keep your favorite songs on your phone, it is recommended to delete those songs and become a Spotify user. So you can stream songs without taking up space on your phone.

How to delete stories from your phone:

1. Go to Settings > General
2. Click iPhone Storage
3. Scroll down to the Music row
4. Delete albums and songs you no longer listen to or press Edit and delete a large amount of music at once.

Photo Stream photos take up space — though not as much as the original photos, because they're uploaded to your device at "device-optimized resolution," according to Apple. You probably don't need these photos because they're probably just duplicates of photos you already have on your device.

• To turn off Photo Stream, open the Settings app, go to the Photos menu, and turn off My Photo Stream. The photos in your Photo Stream are deleted from your iPhone, but they remain on any other devices (such as your iPad or computer) that have Photo Stream turned on.
• They also remain in your iCloud account for 30 days from the date they were uploaded.

• If you use Safari constantly, your iPhone may store web history and data that you may not need.
• Safari browser cache is cleared from two places, go to Settings -> Safari -> Clear history and Website Data and Settings -> Safari -> Advanced -> Website Data -> Remove All Website Data.
• If you're using Chrome instead of Safari, open the Chrome app and tap the three-dot button in the upper-right corner. Then tap History and select Clear Browsing Data at the bottom of the screen.

• Safari's offline reading list can be used to read unnecessary space-saving web pages when you don't have an Internet connection. To delete your Safari offline reading list, open the Settings app and select General > Storage & iCloud Usage. Tap Storage > Manage Storage > Safari. Select Offline Reading List and select Delete to clear the cache.
• This doesn't delete individual items from your reading list: to do this, open Safari, go to your reading list, and delete the items you want to delete.
