Hi, I'm Carl. I was wondering how long iPhone update takes usually. I set my iPhone 13 for iOS 16 update nearly a couple of hours ago and it's yet not been any further then Apple logo. I'm talking about OTA update by the way. Any help is much appreciated.

Evidently the update of Carl's iPhone is stuck. If you have encountered a similar problem like Carl, maybe your iPhone is stuck on other stages when updating, fret not! Assuming that you're connected to a high speed internet connection (a Wi-Fi, for instance) and have sufficient amount of space available in your device, here are some information that may help you to deal with your situation.

1. How Long Does It Take to Update iPhone Generally

To answer the question "how long does it take to update iPhone" we carried out some math. We noted down the approximate time fragments required to get through the OTA update process and came up with these numbers. Depending upon your internet connection speed, the iOS update download may take up anywhere between 2 to 15 minutes. Later, the installation may eat up nearly 5 to 20 minutes. Lastly, setup iOS 12 for first time use requires another 2 to 5 minutes. That concludes, 15 to 40 minutes is generally the total time consumed to get through an OTA update process.

Download iOS 12
2 to 15 minutes
Install iOS 12
5 to 20 minutes
Set up iOS 12
2 to 5 minutes
Total Time Consumed
10 to 40 minutes

Note: The values defined above are not the exact values rather are just an approximate time frame you should keep aside, in general, when opting to upgrade your iOS firmware version. The time that iPhone update takes exactly cannot simply be defined because that varies from device to device.

2. What Influences the Time that an iPhone Update Takes

Well, the greatest and the deciding factors which actually answer to these questions are on what iOS version your iPhone have currently and how much data you have on your device now. That implies:

  • If you're running on iOS 12.1.1 and are upgrading to iOS 12.1.2 or iOS 12.2, the list of advances required are the least, eventually, decreasing the update size to the least. For your information, iOS 12.2 update for a new iPhone X is available at only 83 MB file size, while for iPhone XS it is 156 MB. For other iPhone or iPad models running on iOS 12.1.1, the update file size's nearly the same as that of iPhone X or XS. But in case you're running on iOS 11.4.1 or older, the list of advances required will be way more higher, eventually, having much larger file size to download.
  • If you have very large size of data, it will take longer time to refresh the software.

Therefore, if you're moving from the former iOS version to the latest one or you are updating an iPhone you bought recently, the time needed is much less.
