Q: New IOS8 is still updating after 3 hours - the icon is scrolling still.  How long should this take?

Hi Marie,

Welcome to Apple Support Communities.

It sounds like you’re upgrading your iOS on your iPhone 5s over the air and it’s taking a long time to complete the download. The article linked below provides information that may explain why it’s taking longer than expected and troubleshooting suggestions that should resolve the issue.

Resolve issues with an over-the-air iOS update

Update does not complete

If you're installing the update and the progress bar appears to move slowly, be patient. The time an update takes depends on the size of the update and the number of files on the device.

 

When you're updating over the air, keep your device connected to a power source so that it doesn't run out of power. If your device does run out of power, connect it to a power source and

turn on the device to let the update or restore complete.

 

If the update never completes and the progress bar hasn't moved for an extended time, try restarting your device. If you still see the issue after you restart, see what to do if your device appears frozen or won't start.

I hope this helps.
