A cracked iPhone usually should be replaced or repaired right away if the crack reaches the display, affects touch, or exposes glass shards. If it’s only a tiny cosmetic crack and everything still works, many people wait a few days to a few weeks, but the risk of the damage spreading goes up quickly with more drops or pressure.

When to replace now

Replace or repair it immediately if you notice any of these:

  • The screen has black spots, lines, flickering, or unresponsive areas.
  • The crack is sharp enough to cut your finger.
  • Face ID, touch, or the display brightness is acting oddly.
  • The back glass or frame is also damaged.
  • Moisture could get in through the crack.

When you can wait a bit

You can usually wait if:

  • The crack is very small.
  • The display still works normally.
  • The phone is protected by a case and screen protector.
  • You can avoid further drops and keep an eye on it.

That said, Apple treats accidental screen damage as a repair issue rather than something that “heals over,” and their out-of-warranty screen repair pricing is listed separately from normal warranty coverage. Apple also says accidental damage protection under AppleCare+ covers unlimited repairs for drops and spills, with a lower service fee than out-of-warranty repair.

Practical rule

A good rule is: if the crack is growing, sharp, or affecting use, don’t wait. If it’s minor and stable, schedule service when it’s convenient, but don’t treat it as long-term safe.

Typical timing

From public repair reports, many people get iPhone screen repairs within about 12–24 months after purchase , but that’s more about when damage happens than when replacement is “supposed” to happen. Repair timing at Apple or service shops can often be same-day to a couple of hours, depending on stock and store traffic.

Bottom line

For a cracked iPhone, the “right time” to replace it is usually as soon as the crack becomes more than cosmetic. If the phone still works and the crack is tiny, you may be able to wait briefly, but the safe move is to repair it sooner rather than later.
