The ba­sics

iOS is the op­er­at­ing sys­tem soft­ware that runs on iPad, iPhone and iPod touch de­vices. It’s the un­der­ly­ing frame­work that or­ga­nizes, launches and runs other apps, and can per­form a num­ber of fea­tures of its own.

Ev­ery sum­mer at WWDC Ap­ple un­veils the lat­est big up­date to iOS; for ex­am­ple, in June 2017 we heard about iOS 11. Then we all get to down­load the new OS in Septem­ber of the same year. There will be smaller point up­dates through­out the year: iOS 11.1 and so on.

Com­pat­i­ble de­vices

Be­fore up­dat­ing, you need to make sure your de­vice is certified as ca­pa­ble of run­ning the new soft­ware. To run iOS 11 you’ll need one of the fol­low­ing: iPhone 5s, SE, 6 6 Plus, 6s, 6s Plus, 7, 7 Plus iPad Pro 9.7in, 10.5in, 12.9in (2015), 12.9in (2017) iPad Air, Air 2 iPad, 4th gen­er­a­tion, 5th gen­er­a­tion iPad mini 2, 3, 4 iPod Touch 6th gen­er­a­tion

Pre­pare your iPhone or iPad

It’s very easy to up­date the OS, but be­fore you do so we rec­om­mend that you take some steps to pro­tect your data be­fore you click yes on that up­date alert.

1. Back up your data

Use iCloud or iTunes to back up your de­vice. This will save the day if you find that mes­sages or pho­tos dis­ap­pear from your iPhone af­ter the up­date. You should be aware that the backup will in­clude pur­chased mu­sic, TV shows, apps, and books; pho­tos and video in the Cam­era Roll; and de­vice set­tings, but it won’t in­clude any­thing you synced from your com­puter. To resync that stuff you’ll need to sync with iTunes. For that rea­son we rec­om­mend back­ing up to your com­puter as well as iCloud.

2. Save a copy of the old ver­sion of iOS

As a gen­eral prin­ci­ple this is a sen­si­ble idea – you may change your mind and de­cide you want to down­grade

from iOS 11 to iOS 10, and this will be eas­ier if you make sure you’ve got a copy of the lat­est ver­sion of iOS 10 com­pat­i­ble with your de­vice. Be­ware though that at some point Ap­ple will stop ‘sign­ing’ older ver­sions of iOS so it will be­come im­pos­si­ble to down­grade.

For fu­ture ref­er­ence, if you have a copy on your hard drive you will find it, by de­fault, by fol­low­ing this path: you­ruser­folder/Li­brary/iTunes and then se­lect the Soft­ware Up­dates folder for your de­vice. (Ac­cess the Li­brary folder in your user folder by hold­ing down the Op­tion/Alt key in Finder and se­lect­ing Go > Li­brary.)

Your Mac may have deleted this file, how­ever. If so, launch your web browser and search for down­load ipsw. You’ll find a num­ber of sites of­fer­ing links to the file you need. Make sure you get the right one for the de­vice you use.

3. Make room on your de­vice

If you have lim­ited space on your phone you may not be able to per­form the up­date – it’s a hefty down­load. To get ready, you can re­move con­tent you no longer need, which is a good idea in any case. Go to Gen­eral > Stor­age & iCloud Us­age > Man­age stor­age and re­move any apps you no longer want. Al­ter­na­tively, you can up­date iOS in iTunes and save your­self the trou­ble.

4. Plug in your iPhone or iPad

Make sure you plug your de­vice into a power source. Run­ning out of bat­tery mid-down­load can foul up the up­date and may cause other prob­lems.

5. Make sure you’re con­nected to Wi-Fi

Be sure you’re down­load­ing over Wi-Fi and not via 3G or 4G, or you may end up us­ing your monthly data al­lowance month.

In­stall iOS 11 1. Go to Set­tings > Gen­eral > Soft­ware Up­date

You should get a no­ti­fi­ca­tion in­form­ing you that a new ver­sion of iOS is avail­able for you to down­load, then all you need to do is con­firm that you’re happy to up­date your de­vice. But if not, take a look in the Set­tings app and scroll down to Gen­eral. Tap Soft­ware Up­date and force iOS to check for new up­dates.

iOS will think for a mo­ment and then present you with the up­date, in­clud­ing the amount of stor­age space re­quired (you may need to clear some space be­fore down­load­ing). Sim­ply con­firm you wish to up­grade and fol­low the steps.

2. Tap Down­load Your de­vice may or may not have down­loaded the in­stall file au­to­mat­i­cally. 3. Leave the up­date to down­load in the back­ground Once the down­load has fin­ished you will re­ceive a no­ti­fi­ca­tion say­ing an up­date is avail­able. 4. Tap De­tails This will take you to Set­tings > Gen­eral > Soft­ware Up­date. 5. Tap In­stall Now Your de­vice will now start to in­stall the iOS up­date. You can choose to leave the in­stal­la­tion for later. Set­tings will display a no­ti­fi­ca­tion badge un­til you have in­stalled the up­date. Fixes for com­mon up­date prob­lems Up­dat­ing iOS is gen­er­ally easy, but there are lots of small things that can po­ten­tially go wrong. 1. Up­date is tak­ing too long We had a com­plete night­mare in­stalling Ap­ple’s mo­bile OS in the past: iOS 7 in 2013, for ex­am­ple, took us all night. We had hoped things might go a bit smoother in 2014 with the launch of iOS 8, but un­for­tu­nately not. Again, many faced in­stal­la­tion dramas be­cause Ap­ple’s servers seemed un­able to cope with the sheer num­ber of peo­ple try­ing to ac­cess them to get the down­load. So if this was your ex­pe­ri­ence it’s not a huge sur­prise, and you shouldn’t feel like you’re alone.

One thing is for sure: if you choose to up­date as soon as a new ver­sion of iOS 8 launched you’re prob­a­bly in for a long wait be­cause the first few hours of an up­date are al­ways the busiest time on Ap­ple’s servers. 2. Not enough space on iPhone or iPad All that pre­sumes you had enough space on your iPhone to start with. As we touched upon one prob­lem when up­dat­ing your ver­sion of iOS is to find that there isn’t room on your de­vice for the in­stall file. One so­lu­tion is to delete lots of files from your iPhone and make room, then put them back af­ter­wards. Another op­tion is to up­date iOS via iTunes on your Mac.

If you don’t need to free up a lot of space you may be happy to delete a few im­ages from your Cam­era Roll or some of your mu­sic.

3. Alarm doesn’t work af­ter up­date

Ap­ple is keen for more users to in­stall in­cre­men­tal iOS up­dates that pro­vide fixes and small im­prove­ments. One way it en­cour­ages this is by of­fer­ing the chance to in­stall them for you overnight while you’re sleep­ing. If you’re prompted to up­date your iPhone while you’re us­ing it, Ap­ple now lets you choose ‘Later,’ which will then spec­ify a time pe­riod dur­ing which it will up­date au­to­mat­i­cally for you if you’ve got your iPhone plugged in to a power source, which most peo­ple do overnight any­way.

When Ap­ple prompted iPad&iPhoneUser’s own Ash­leigh Macro to up­date to iOS 9.1 and of­fered that ‘Later’ op­tion, she de­cided to make the most of the con­ve­nient new fea­ture. She ex­pected to wake up in the morn­ing as usual to an up­dated iPhone. And in­deed she did, but she woke up more than an hour af­ter her alarm was sched­uled to go off. The up­date had worked bril­liantly, but her alarm had been de­ac­ti­vated, caus­ing her to be very late for work.

She’s not the only one. Users have taken to so­cial me­dia and fo­rums to ex­press their an­noy­ance with the is­sue, which we con­sider to be a bug, and many have been late for im­por­tant meet­ings and school.

There­fore, we’d only rec­om­mend choos­ing the later op­tion if you don’t have to wake up at a par­tic­u­lar time in the morn­ing, or if you can set another alarm on a dif­fer­ent de­vice.

You may need to delete some apps to free up space for the up­date
