iOS 15.7 Update Download Failed

Storage capacity is one of the most common causes of iOS updates failing. The solution is simple if you are willing to make some temporary sacrifices, such as eliminating music, apps, images, and movies. There must be just enough deletions to make room for the iOS update's storage requirements.

TL;DR; I looks like you need at least 6GB of free storage to install this update (at least in my case).

I have an iPhone 12 and I had a problem with installing 15.7 on 15.6.1. I literally try everything to update. Restarting (up+down+power), turning off, using different networks types and providers, starting with different battery levels, with power plugged in and not. I tried for 3 days. Mostly because every time I got error message that there was a problem with downloading. That was really confusing. But apparently it’s a problem with unpacking and preparing an update. I started to free my phone memory checking if I can update after each app/file deletion. It worked just after I got to 6GB of free memory.

Shame on Apple that they didn’t confirm-

/tested the requirements and that this upgrade need so much free space. Also more useful error messages would be appreciated.

Do not tell us what to do here.

I had NO issues in updating three iPads to iOS 15.7.

No one here with this issue, to date, has given to those who wish to help, all information that is needed to be able to give solid advice or redommendations to attempt to solve this issue.

So, I will ask now.

Can anyone, with an issue updating to iPadOS 15.7, please, confirm what year and model iPad do you have/own?

The “A” model number can be found on the aluminium back of your iPad, in very small print, right under the larger bold print “iPad” on the back of the iPad.

What iOS/iPadOS version is this iPad, currently, running?

What is the rated, internal data storage space/capacity of your iPad model and how much of this free, internal data storage capacity is left inside of your iPad model?

All of that additional info can be found in the Settings app, General settings panel, About.

Please try to make an attempt to answer all questions asked.

Thank You.

I faced this problem as well, after trying different ways (using cellular data, on wifi, air, while charging etc) finally I could update it while my phone was 100% and still charging and I was connected to the Wi-adi. My device it’s an iPhone 11 and it could be a bug or something so I recommend to try the way that it worked for me. Cheers!

I had the same problem with my second generation Iphone SE. it all finally worked when I freed up enough space to get to 6.3 GB, it didn’t work when I tried at various intervals along the way.

At the same time my iPad Pro 2nd generation had no problem updating IPad iOS 15.7 with only 2Gb free space.

Thank you for your input, it’s much appreciated. Cheers.

You should NOT be using any iPad with ONLY 2 GBs of internal, free data storage space.

ALL iOS/iPadOS devices need to maintain, at the very least, a minimum of between 3-6 GBs of free data storage space, AT ALL TIMES, to insure normal/nominal functionalities/operation and general overall performance of any iOS device running iOS/iPadOS..

Same problem. No help so far. Is there any help updating to iOS 15.7 in XR iPhone Keeps getter error same as above.

help !

The 2nd gen mini is only able to be upgraded to iOS 12.x so that could be the issue.

Are you guys trying to download over Wifi or cellular? If cellular do you want to try to download it on wifi?

Thank you, I'll give that a go. I restarted my iPhone once, but I will leave it off longer. Thanks for your help, and glad you have progress!

It is not my screenshot. It was provided from someone else.

I am having the same issue and I have tried wifi, cellular, and lots of frustrating moments.

free up space on phone, probably around 10Gb fro full capacity should be free

Thank you, that’s normally where I operate at 3-6GB. Having an external storage device has made big help. What’s not helping is the new apps are eating way too much storage with each update.
