Your iPhone is capable of performing many wondrous tasks. Some of which, you’re probably not even aware of. So let us enlighten you on the hacks that will save you time and effort. You’re welcome.

1. You don’t have to delete all your photos when your storage is full.

There are few notifications more frustrating than this one:

The good news is that you don't have to delete all of your photos (read: selfies) to get this snap. Instead try freeing space other ways, such as deleting your old voicemails, unwanted text threads or clearing your browser history.

You can do this by going to settings, selecting 'Safari' and press 'clear history and website data.'

2. Know who's texting you without looking.

You don't have to be psychic to know who sent you a text without looking at your phone. You can customise the vibration and ringtone for each of your contacts. For instance, you might like to make your bosses ring tone "alert" and the vibration to "S.O.S".

To make the change open a contact page in your phone book and click edit. Scroll down to "text tone" and "vibration" and then pick your desired tone and vibration for that person.

3. Stop your music automatically when you fall asleep.

If you're one of those people who likes to listen to music or an audiobook before you go to sleep, this is an incredibly handy trick.

Instead of dozing off to a playlist and waking up in the middle of the night confused as to where the sound is coming from, you can actually use your clock app to set the playlist or book to turn off automatically after a certain amount of time.

Simply go into your clock app and select timer on the bottom right. Select how long you want it to play for (depending on how fast you think you'll fall asleep!), then click on "When timer ends" and scroll down to select 'Stop Playing'. Press 'set' - and you're done!

4. Make movie plans without the fuss.

Wouldn't it be amazing if you could tell your iPhone that you would like to see a movie tonight and your phone responded by giving you a comprehensive list of all the movies playing near you? It's easy to do.

Simply ask Siri  "What movies are playing tonight" and she will give you a list of options in your area?. You can then tap on your favourite option to get a description of the movie, the running time and directions to get there.

5. Undo typing, Taylor Swift-style.

Instead of hitting the delete button, just shake your phone from side to side and it will delete the last section of writing you typed. It may not be much faster then pressing the delete button, but shaking your phone is way more fun, right?

6. Save your battery.

iPhones are unfortunately notorious for eating through their battery power. But there is a way to avoid losing your precious battery life - use aeroplane mode. It's not just for when you are flying, switching to aeroplane mode stops any incoming calls/texts/internet data.

So next time you don't need to use your phone, like in a meeting at work, just switch it to aeroplane mode.

Need to charge your phone but heading out? Flicking onto aeroplane mode before charging will also speed up the process.

7. Get the perfect picture - the first time.

Have you ever taken a really important picture only to look back and see your eyes were closed? Me too. A simple way to ensure you capture the moment in the perfect picture is to hold down the camera button. The longer you hold it the more photos it will take.

When you go back into your photos, it will have all the photos stored there for you in 'bursts'. Simply click on the burst, select the pictures you like and then delete the rest!

8. Create a passcode with letters

Better at remembering words than numbers? Your passcode doesn't have to be a four-digit number - simply go into 'Settings', 'General', 'Passcode Lock' and turn off the 'Simple code' option.

You'll get asked to change your passcode and the normal keyboard will pop up instead of just the number pad. This will also come up when you need to unlock your phone.
