Your iPhone slips off the sofa, hits the floor, and you pick it up for the dreaded inspection. Screen is fine, camera still works, but the back glass looks like a spiderweb. It still works, so do you just slap a case on and ignore it?
As someone who fixes these every day at Repair My Crack, I hear this a lot. The short answer is: you usually should not leave cracked back glass for too long, even if the camera is fine. You can get away with a short wait, but there are risks that creep up over time.
In this guide I will walk you through what is actually at risk, rough costs in the UK, and when it makes sense to repair now instead of putting it off.
Should you repair cracked iPhone back glass now or later?
If the damage is only light, no sharp edges, and you keep the phone in a case, you can usually wait a little while. Plenty of people do this, especially if payday is a week away.
The catch is what happens if you leave it for months. Cracks tend to spread, the frame can start to flex, and tiny gaps open up around the camera or wireless charging area. That is when dust and moisture sneak in and things get expensive.
Back glass is not just for looks. As Apple’s own repair information explains, that glass helps protect internal parts and keep water resistance. Once it is cracked, the seal is not what it used to be.
Here is how I usually put it to customers at the counter:
- Light crack, always in a case, you are careful: waiting a short time is usually fine.
- Deep cracks, missing chunks, sharp edges, or you use wireless charging: get iphone back glass repair done sooner.
If the phone is already valuable to you, sorting the back glass now is almost always cheaper than waiting for it to cause a bigger fault.
What a cracked iPhone back actually puts at risk
A lot of people think cracked back glass is just cosmetic. It is not.
A smashed back can lead to:
- Water getting in: modern phones rely on glue and gaskets, not magic. Once the glass is cracked, water resistance takes a hit. Articles like this truth about smashed iPhone back glass explain how quickly moisture can cause trouble.
- Camera issues later: your camera might be fine now. Over time, a bent frame or loose glass can push against the camera housing and cause focus or blur problems.
- Wireless charging problems: cracked back glass can affect the alignment of coils and create hot spots.
- Cracked fingers and clothes: fine glass splinters catch on pockets, cases, and skin. I see this a lot with people who kept using the phone “for now”.
If you already have a cracked front as well, then back glass plus iPhone screen replacement in one go often works out better than doing them separately. Most people who ask “is it worth repairing a cracked iPhone screen” end up agreeing once they realise how much more a new phone costs.
How much does iPhone back glass repair cost in the UK?
Prices vary depending on your model and who you go to.
Apple often replaces the whole housing, which can be on the pricey side. You can see typical approaches on Apple’s iPhone repair and service page. Many people look for alternatives to Apple Store screen repair UK and back glass repair, because they want to save money but still get quality parts.
Independent repair shops and postal services usually:
- Replace only the back glass, not the whole shell.
- Use laser or heat machines and OEM-quality parts.
- Charge less than Apple, especially on older phones.
Guides, like this breakdown of iPhone 13 rear glass replacement cost, show typical UK pricing and what affects it.

Screens, batteries and other repairs to sort at the same time
Cracked back glass is often not the only issue. While your phone is open, it can be a good time to deal with other annoying problems.

Is it safe to keep using my phone?
For a short time, usually yes, if:
- The crack is small.
- There are no sharp bits.
- You keep it dry and in a case.
Long term, it is a risk for water, dust, and extra damage, so I still recommend repair.

People often ask how long does phone screen repair take UK wide. In our shop we aim to complete most screen jobs the same day they arrive, and back glass is often similar. Postal jobs add a couple of days for travel, but we still keep it as quick as possible.
