How long does it take?
Just like backups, there are two commonly used ways to restore your iPhone: via the internet-based iCloud service, or using the conventional iTunes.
Restoring your iPhone using iCloud will of course really depend on your internet speed. Even with 100 MBps Internet Speed, the restoring process still can take anywhere from 1 to 4 hours.
Therefore iTunes remains the first choice of most people because the process only takes between 15 to 30 minutes.
What affects the restoration time?
Amount of data on your iPhone
This seems no longer surprising. Logically, the larger the data you want to restore, the longer it will take. That’s why it is possible to have a minimum number of files to fasten the whole process.
iOS update
If an iOS update is available, it will take longer for iTunes to restore your iPhone. What’s more, the size of the update is pretty big by itself.
Internet Network
Before you start restoring your device, you should check your internet speed. A fast internet network will certainly speed up the restoring process. On the other hand, a slow internet network will hinder the process.
Conclusion:
Restoring your iPhone is a process that will take time. For this reason, it’s important to backup your data before restoring the device back to its default state or factory settings.
