Frequently asked questions
How long does an iPhone update take?
Small updates take 10 to 20 minutes. Major updates can take 30 minutes to an hour, longer on release day when Apple’s servers are busy.
Will updating my iPhone delete anything?
No. Updates keep your photos, apps and settings. It is still smart to back up before a major update in case something goes wrong.
