11. Sounds: get some new tones

iOS 7's library of sounds (Settings > Sounds > Sounds and vibration patterns) has been given a regular update, and Apple says they're so good you might miss calls because you're dancing. That, frankly, isn't very likely.

12. AutoFill: let Safari input your details

Feeling trustworthy? Safari can automatically fill out web forms using your Contact info, previous names and passwords, and credit card details, should you so wish. You can toggle these AutoFill options individually from Settings > Safari > Passwords > AutoFill.

13. Siri: now reads your emails

Siri makes light work of not only listing emails in your inbox, but also reading them out to you. Hold down the Home button and say, "Read my emails" and Siri will give you sender, time and date sent, and the subject of each in turn. When asked if you want it to read out your mail, just say "Yes".

14. Apps: one folder to rule them all

Unlike previous versions of iOS, there's no limit to the number of apps you can file away in a single folder. Now you can simply pile icons onto each other to your heart's content. Finally, an end to the Games 1, Games 2, Games 3 (ad nauseum) home screen debacle.

15. Motion: reducing sickness

iOS 7 likes to advertise its existence to you with all manner of motions, animations and alerts. If all the hullabaloo is leaving you slightly queasy, put a dampener on things by selecting Settings > General > Accessibility > Reduce Motion > Off.

16. Notification Centre: not on my lock screen

Notification Centre got a visual overhaul in the latest version of iOS, offering a neat snapshot of your appointments and message snippets accessible from the lock screen. But not everyone wants their itinerary on show to all and sundry. Happily you can turn off this overview from Settings > Notification Centre, using the sliders listed under - you guessed it - 'Access on Lock Screen'.

17. FaceTime: data and duration

You can check out your complete list of FaceTime calls via the Recents option at the bottom of the screen in the FaceTime app. If you tap the "i" next to each call you can see a breakdown of how long the call lasted and find out how much data it used.

18. Maps: walk or drive everywhere

Maps still has its downsides, but it's useful for the most part - more so now that you can choose a default mode of travel. If you're more rambler than driver and want to avoid having to define your directions as such, simply tap to Settings > Maps and select Walking under Preferred Directions.

19. App Store: Near Me

A new tab in the App Store app called Near Me automatically lists the most popular apps in your general location. That might sound a bit gimmicky, but we found it useful when visiting towns and cities for the first time, when it turned up local transport and tourist information apps.

20. Apps: Background App Refresh

iOS 7 introduces the ability to selectively control which apps are allowed to refresh their content while you're getting on with other business. When battery life is at a premium, turn off any offenders by going to Settings > General > Background App Refresh.
