Replacing an iPhone screen yourself is a realistic DIY repair if you're comfortable with small tools — most people complete it in under an hour once they have the right part and equipment. The screen sits directly over the battery and is sealed with adhesive, so the process rewards patience over speed rather than mechanical skill. This guide covers the general steps that apply across the iPhone 16 range; exact screw positions and adhesive amount vary slightly by model.
Before you start: get the right part
Fitting technique is the same regardless of model, but the part isn't interchangeable between iPhone 16 variants. Confirm your model and choose LCD or OLED before ordering:
- iPhone 16 OLED screen — £139.98
- iPhone 16 Plus LCD screen — £34.98
- iPhone 16 Plus OLED screen — £145.98
- iPhone 16 Pro LCD screen — £45.98
- iPhone 16 Pro OLED screen — £149.98

Tools you'll need
- Replacement iPhone screen assembly (matched to your exact model)
- Pentalobe and Phillips precision screwdriver set
- Heat source — a heat pad or hairdryer on low
- Suction cup
- Plastic opening picks (never metal, near the battery)
- Spudger
- Tweezers
- Replacement adhesive strips
- Isopropyl alcohol and a lint-free cloth
General process
- Power off the phone completely before starting — never work on a live device.
- Remove the two pentalobe screws at the bottom edge, next to the charging port. Keep them separate from any other screws; iPhone repairs use several screw lengths and mixing them up can damage the frame.
- Warm the screen edges evenly to soften the adhesive seal — move the heat source continuously rather than holding it in one spot, which risks damaging the panel underneath.
- Apply the suction cup near the bottom edge and gently create a small gap, then slide a pick in to release the adhesive — work carefully, the screen opens like a book from the bottom, hinged at the top.
- Prop the screen open on a stand or stack of books and locate the battery connector shield, usually held by one or two small screws.
- Disconnect the battery connector first, before touching any other cable. This is the single most important safety step in the entire process, and skipping it is the most common cause of accidental damage during a screen swap.
- Disconnect the display and any remaining cables, then fully remove the old screen.
- Clean old adhesive from the frame with isopropyl alcohol and a lint-free cloth — residue left behind can prevent the new screen sitting flush.
- Connect the new screen's cables, reconnect the battery, and power on to test display, touch and Face ID before sealing. This step is easy to skip when you're keen to finish, but it's the difference between a five-minute fix and a full re-opening if something's not seated properly.
- Once confirmed working, power off, apply fresh adhesive, and seal the screen back into place.
Why testing before sealing matters more than it seems
Direct answer: once the screen is sealed with fresh adhesive, reopening it to fix a loose connector or a display fault means repeating the heat-and-pry process on adhesive that's already been disturbed once — harder the second time, and more likely to mark the frame or panel. Testing before final sealing costs you two extra minutes and eliminates almost all of that risk. It's the single easiest step to skip when you're eager to finish, and the one most worth resisting that urge for.
Common mistakes that turn a simple repair into a costly one
| Mistake | Why it matters |
|---|---|
| Not disconnecting the battery first | The biggest risk in the whole process — can short the board or damage the battery |
| Too much heat, held in one spot | Can damage the OLED panel or nearby components, particularly on original-spec parts |
| Sealing before testing | Turns a two-minute check into a full reopening if something's wrong |
| Using metal tools near the battery | Risk of puncture and fire — plastic tools only, always |
| Mixing up screw lengths | Wrong screw in the wrong hole can crack the frame or damage internal components |
How this repair differs slightly by model
While the core process above applies across the iPhone 16, 16 Plus and 16 Pro, a few small differences are worth knowing before you start. The 16 Plus's larger frame gives marginally more room to manoeuvre picks and tools during opening, which some first-timers find easier. The 16 Pro's screen, particularly the original-specification LTPO OLED option, carries a more complex flex-cable arrangement to support ProMotion and always-on display, so handle those connectors with slightly more care during disconnection and reconnection than you might on a standard LCD swap. None of these differences change the overall process or timeframe meaningfully — they're refinements to the same core technique, not separate procedures.
What to do if something doesn't work after fitting
If the display stays black after reconnecting, check the display connector is fully seated before assuming the part is faulty — a connector that looks connected but isn't fully clicked in is the most common cause of a "dead" new screen. If touch doesn't respond in a specific area only, check that area's connector similarly. If Face ID fails, confirm the TrueDepth sensor cluster wasn't disturbed or damaged during removal — this is a separate component from the screen itself, covered in more depth in our diagnosis guide. Genuinely faulty parts are covered by our 30-day returns policy if the issue persists after confirming correct fitting.
Preparing your workspace properly
Before opening the phone, set up a clean, well-lit, static-free work surface, ideally with a soft mat to protect both the phone and the small screws you'll be removing. A magnetic project mat with labelled sections for each removal step is inexpensive and genuinely useful — iPhone repairs involve several similarly-sized screws that are easy to mix up if left loose on the table, and using a screw that's slightly too long in the wrong hole can damage the logic board underneath. Good lighting matters more than people expect too: the adhesive seal and connector latches are small, and working in poor light increases the risk of missing a still-connected cable when you think the screen is fully free.
A note on adhesive quality
Not all replacement adhesive strips are equal, and this is one area worth not cutting corners on even if you're being budget-conscious about the screen itself. A poor-quality or incorrectly-sized adhesive strip can leave gaps at the edges of the screen, which over time allows dust and moisture to work their way in — undermining water resistance the phone may have had from the factory. Genuine pre-cut adhesive strips designed for your specific model, applied carefully and given time to properly bond before use, give the best chance of restoring the phone's original seal integrity as closely as a DIY repair reasonably can.
When to hand it to a technician instead
If you're not confident with any of the steps above — particularly the battery disconnection or heat application — buying the part here and having a technician fit it is a reasonable middle ground. You still save on their parts markup versus a shop supplying and fitting their own screen, without taking on the risk of a first-attempt repair on a device you rely on daily.

Frequently asked questions
How long does it take to replace an iPhone screen?
Most people comfortable with small tools finish in well under an hour; first-timers should allow longer, particularly for the adhesive removal step.
Will Face ID still work after a screen replacement?
Face ID depends on undamaged sensor components near the screen, not the screen itself — test it before sealing the phone back up, and avoid damaging the sensor cluster during removal.
Do I need to disconnect the battery?
Yes, always, before touching any other connector — this is a basic safety step for any phone repair, not an optional precaution.
What happens if I seal the screen before testing it?
If something's not working, you'll need to reopen the phone and disturb the adhesive a second time — harder and riskier than testing first, which only takes a couple of minutes.
Can I reuse the old adhesive instead of buying new strips?
Not recommended — old adhesive loses its seal strength once disturbed, and a poor seal risks dust and moisture ingress. Fresh adhesive strips are inexpensive relative to the rest of the repair.
Is it worth doing this myself, or should I pay a technician?
If you're comfortable with small tools and methodical, yes — it's a genuinely achievable DIY repair. If any of the steps make you uneasy, particularly around the battery, supplying the part to a technician still saves their parts markup while removing the risk.
Is fitting a 16 Pro screen harder than a standard iPhone 16?
Not fundamentally — the Pro's original OLED option has a marginally more complex flex-cable arrangement for ProMotion support, worth handling with a little extra care, but the overall process and timeframe are essentially the same.
My screen is black after fitting — what should I check first?
Check the display connector is fully seated — a connector that looks connected but isn't fully clicked in is the most common cause of a black screen after a fit that otherwise went correctly.
Does the quality of the adhesive strip actually matter?
Yes — a poor-quality or incorrectly-sized strip can leave gaps that let dust and moisture in over time, undermining any water resistance the phone had from the factory.
What workspace setup helps most for this repair?
A clean, well-lit, static-free surface with a magnetic project mat to keep track of screws by removal step — iPhone repairs use several similarly-sized screws that are easy to mix up.
