How Long Will the iOS 5 Upgrade Take?



When iOS 5 finally shows up for the masses, you might want to know how long you should plan for the upgrade.

Unlike a computer OS upgrade, and iOS device won’t take hours, but it’s not like downloading and installing an app either.

Before you do the upgrade be sure to read our guide on what to do first and on how to perform the upgrade.

If you are thinking about upgrading to iOS 5 before you head in to work or before you leave for the day, make sure you have enough time, or you might have to leave without your iPhone!

Sync and Backup – 1 to 15 Minutes

iTunes will first perform a sync of your iOS device after you connect your iPhone, iPad or iPod Touch to the computer. If you haven’t performed a sync in a long time, it might take quite some time. Any content that you’ve downloaded directly on the device like music, videos, books, apps and more will take a while to copy over to the computer. Some apps also take a long time to back up to the computer. I have a couple of library apps that hold books that I need for my other job. This app alone adds five minutes to the backup process.

Transfer Purchases – 1-15 Minutes

Just to be safe, I always manually do a backup and transfer purchases before upgrading. Like syncing this time depends on how long it has been since you last performed this step.

iOS 5

Downloading iOS 5 – 15-20 Minutes Depending

The longest step in this process could be downloading the new version of iOS from Apple. Depending on your Internet connection speed, this can take quite a long time. On my cable connection and it usually takes about 15-20 minutes. Slower DSL or dial-up will take much longer. If you have FIOS or a really fast connection it might just take minutes.

Installing iOS 5 – ~10 Minutes

After the update has been downloaded iTunes will start the actual process of installing the new version on your device. In my experience this usually take about ten minutes.

Restore from Backup – 5-10 Minutes

Once complete you have a chance to set up the device as a clean device without anything on it or you can restore from the backup. If you want to have all of our apps and content just as it was before the update, do the latter. This will take another ten minutes or more depending on how much content you had on your device before the update.

How Long Does it Take to Upgrade to iOS 5?

For most users, expect to take about an hour for this process to go from start to finish. Below are the estimates based on my experience updating iPhone and the iPad over the last three years. For me the update process usually comes closer to the lower number than the higher numbers.

Initial Sync 2-3 Min
Backup and Transfer of Purchases 3-30 Min (low end)
iOS 5 Download 5-30 Min
Device Firmware Update 10-15 Min
Restoring Backup 5-15 Min
Total 25-88 Min

Start the process at least 90 minutes before you will need your phone for any critical tasks.

If you plan to buy an iPhone 4S in the next week, should you go through the bother of installing iOS 5?

Even if you only get the use of it for a couple of days, I would suggest that it will be worth the 90 minutes it could take.

First, you will be able to get access to the new tools and features. It will help you get used to your new phone.

Second, whoever will get your old phone will appreciate it much more. Handing it down to a family member or friend? They will appreciate the effort. Finally, if you are selling the phone, it may be worth more to someone if you advertise it as having iOS 5.

    for users whose iTunes are unable to prompt you for the update, probably you are not using the previous version (4.3.5). download the old version and go to your iTunes > help > check for updates. it will prompt you the latest version of iOS 5.

    Mine told me it was going to take 12 hours, then after a while the ETA jumped to 24 hours, then it timed out and disconnected.  lol

    No surprise here at all.  Windows has always been horrible with iOS updates in my opinion.  about 66% the time my device completely crashes and I have to reinstall everything (iTunes included) and I lose all my data.  These days I manually back up all my contact info and my calenders, I just don’t trust iTunes to keep it safe.

    Ninety minutes would be a godsend.  My iPhone 4 is taking FOREVER.  The restore failed the first time.  Finally got the thing onto iOS5 but the “syncing music” step is moving into hour four and is about 80% complete.  So far I’m 6 1/2 hours in.  This is on a new Mac Mini, the media server machine I syn my phone to.  On a separate endeavor, updating my iPad 2 on my MacBook Pro is moving into hour three.  Pretty nuts!

    The most hilarious part of this article is that because of how bogged down the servers are, it’s been over 4 hours and I still only have 70% of this 700mb file! iTunes estimates 6 hours total. What a joke.

      My 16Gig iPad 1 has been running the update for over 3 hours. It is now into the restore phase and I estimate another 3 hours. The Ipad has a pretty full hard drive but this backup and restore speed is unacceptably slow

  55. Klakjw1

    10/16/2011 at 6:55 pm

    I just want to say that 90 minutes is not long enough. U should let it update overnight because it is telling me that it will tale about 7 hours. It took about 6 to update iTunes. Although my backup was quick. Why would you get a new phone if u updated your old one. It will be pretty much the same thing. That seems like a waste of money to me.

Is it normal for it to be showing the apple logo & intermittently bleeping, giving a glimpse of a screen saying iPad. Also it no longer shows up on iTunes as a device!

    It is almost 2 days. My computer was continuously busy to back up! Oh, just for this Upgrade, my PC can go FUCKED UP! Apple is a fucked up company. They produced iPhone what cant work without their own Mac. But, a cheating technique iTunes for Windows they have! How much really efficient iTunes? to load 235 MB Music from a Sony Vaio, it takes 15 hours! Tomorrow i will put my motherfucking iPhone in ebay. If I find Steves Jobs, i will kick his ass. A real asshole!

    Everybody has been referring to an approx download time that the system was providing you. I’m hearing all of these horrific number of hours. My problem is that I don’t know if it is even doing anything at all. All I see is a little popup box in the middle of the screen that says, “Contacting the iPhone software update server.

    Does that mean that it hasn’t even been able to connect to the server to start the download process. Its been sitting on this same screen for about 6 hours. I am updating a 3GS iOS to the 5.1. If it really takes 5,10,15,20 hours to complete like some of you are saying, then that’s what it is and I’ll have to deal with it. I just don’t want to wait for nothing if it hasn’t even started it yet. Where does it tell you how much time is left for the download. I can’t find that information. Can anyone help.

    That’s is a complete and utter LIE!! I am performing the software update at this minute, and it says that it should take just over an hour so in total it is much longer than what is stated.

      It now says 2 bloody hours. P.S. I am downloading iOS 5.1.1. which only has a few more perks than iOS 5. Any decent, truthful help would suffice within the next 40 minutes.
