Why is the new update taking forever?
it taking forever to update
Question marked as
Some of the new updates are complete replacements of the iPhone's software, so the download can be Gigabytes in size. Depending on your network speed it might need anything between tens of minutes or several hours.
When the download has completed it then has to be decompressed and verified, which is usually the stage where nothing seems to be happening but behind the scenes your iPhone is working like crazy. Finally the decompressed image gets installed and activated, which is a rather extended reboot process.
Just let it get on with the update, it will all happen in its own time (or it will display an obvious failure message). Don't be tempted to crash out of it and start again, because all that achieves is to throw away the progress already made. The worst case scenario on a forced interruption is that the device is restarted at a critical time and ends up with corrupted software, bricked and unable to recover.
