software update bug

Click on the Get Support link at the top of this page. I hope they can fix it, but if not it will be logged, and, if it is a broader problem there will be a record of this similar problem.

You can also update using your computer as a workaround if you don’t want to wait for a fix.

Your phone is in low power mode. It will not update in low power mode.

I wasn’t answering you.

For your issue try force-quitting the Settings app→Close an app on your iPhone or iPod touch - Apple Support, and let us know if that fixes it, because I’ve seen some other reports of this issue and I’m currently just as mystified as you are. I did not have this problem updating our 4 iOS devices.

If that doesn’t fix it try restarting your phone→Restart your iPhone - Apple Support

I have the same problem with three iPhones, tried closing apps and force restart of devices, didn't help. I think that simply many people are jumping to this update given the communicated seriousness of the security fix, my bet would be that this is an overload problem with the update infrastructure

I have the same issue and with three different models of iPhones in my family. Apple System Status page shows all systems operational, hope this gets sorted quickly given the importance of 14.5.1

That's not the issue, my three iPhones are NOT in low power mode
