Phone repair, in store
I dropped it in the car park on a Tuesday morning and had written the phone off in my head by lunchtime. They took it in, quoted me on the spot and handed it back the same afternoon with the old panel in a bag so I could see what had actually broken.
Alicia R.
iPhone 14 Pro screen repair
It was down to twenty percent before lunch every single day and I assumed I was being sold a new battery whatever I said. They tested it in front of me first, showed me the health reading, then swapped it and had me out inside the hour.
Tomas G.
Galaxy S23 battery replacement
I put a full cup of coffee across the keyboard and had four years of work on there with no backup. They opened it the same day, cleaned the board properly rather than just drying it out, and every key on it still works months later.
Priya N.
MacBook Air liquid damage
The last place I used quoted one number on the phone and a different one at the counter. These people looked at the port, told me what it would cost before they touched anything, and that was exactly what I paid when I collected it.
Kevin M.
iPad 10th generation charging port
The back was shattered end to end and pieces of it were coming away in my hand. I left it with them on my lunch break, came back after work, and there is no seam and no gap anywhere on it. You would not know it had happened.
Samuel O.
Pixel 8 back glass repair
What actually decided it for me was the 90 day malfunction warranty, because I had been burned by a cheap repair before that failed inside a fortnight. Nothing has gone wrong with this one, but I would have had somewhere to go if it had.

What we fix
iPhone Repair Types
A cracked screen can involve more than broken glass. You may notice:
Cracked front glass, Touch areas that no longer respond, Black spots, Colored lines, Screen flickering, Dark areas, A screen that responds only sometimes
If the display is damaged, screen replacement may be the appropriate repair.
An inspection can also help determine whether the screen is the only component affected by the damage.
What About Face ID? Screen damage, impact damage, or problems around the front camera area can sometimes affect Face ID.
During an iPhone screen repair, Face ID should be checked before and after service.
The available repair options depend on which component has been damaged and the exact iPhone model.
If Face ID is already not working, mention this before the repair begins.
What About True Tone? Display replacement can affect features such as True Tone depending on the iPhone model, replacement display, and repair process.
If keeping True Tone is important to you, ask what display part and repair process will be used before approving the repair.
An iPhone battery naturally loses capacity as it ages. Signs that your battery may need attention include:
Battery draining much faster than before, Unexpected shutdowns
Needing to charge several times per day
Reduced Battery Health, A battery service message in iOS
You can check your battery information by opening: Settings → Battery → Battery Health.
A lower maximum capacity does not automatically mean the battery must be replaced.
However, significant battery wear combined with poor daily performance can make battery replacement worth considering.
CELLTECH can inspect the battery and explain the available repair options.
An iPhone that is not charging does not always need a new battery. Charging problems can come from:
A damaged charging cable, A faulty wall adapter, Debris inside the charging port, A worn charging connector, Port damage, Another hardware problem
Before visiting, try another compatible charging cable and wall adapter if one is available.
If the charging problem continues, the device can be inspected to help identify the cause.
If the charging port or another repairable component is causing the problem, CELLTECH can explain the available repair option, estimated repair time, and cost before work begins.
Lightning and USB-C Charging Ports: different iPhone generations use different charging connections.
Many older iPhone models use Lightning.
Newer iPhone generations use USB-C.
The repair part and diagnosis can therefore depend on the exact iPhone model.
Camera problems can affect both photos and videos. Common symptoms include:
Blurry photos, Camera unable to focus, Black camera screen, Shaking image in the viewfinder, Damaged camera lens glass, Front camera problems, Rear camera problems
Sometimes the outer camera glass is damaged while the camera itself still works.
In other cases, the camera component may also need attention.
An inspection helps determine which part is actually causing the problem.
Back glass damage is common after drops and hard impacts. You may see:
Cracked rear glass, Missing pieces of glass, Sharp edges, Damage around the camera area, Damage around the frame
Back glass repair can vary considerably between iPhone models because the rear construction and repair process are not the same across every generation.
CELLTECH can inspect the damage and explain the available back glass repair options for your model.
If your iPhone has been exposed to water or another liquid, avoid charging it while the device or charging connection is still wet. Do not put the iPhone in rice. Liquid can reach more than one component, and the visible symptom may not show the full extent of the damage. If possible, leave the device switched off and bring it in for inspection. Liquid damage repair begins with diagnosis because the repair depends on which components have been affected. Because liquid damage can affect several components at once, repair time can vary more than a straightforward screen or battery replacement.
The type of replacement part used can affect the repair experience. Newer iPhones can show information about replaced components under Parts and Service History. The information displayed can depend on the part installed, the iPhone model, and whether any required repair configuration has been completed. Before approving a repair, you can ask:
What type of replacement part will be used?
Is the part new or previously used?
Will any iPhone features be affected?
Does any setup or configuration need to be completed after installation?
How long will the repair take?
Clear answers before service can help prevent surprises later.
Models
Which iPhones Can CELLTECH Repair?
CELLTECH provides repair services for many current and previous iPhone generations. Repair options and parts availability can vary depending on the exact iPhone model and the repair required. Not sure which iPhone you have? Open: Settings → General → About. Then look for a model name. If you cannot access the device, bring it with you, and the store can help identify the model. Once the model is confirmed, CELLTECH can check which repair options and turnaround apply to it.
How it works
How a CELLTECH iPhone Repair Works
1. Tell Us What Happened
Tell us what the iPhone is doing: a cracked screen, a battery flat by lunchtime, charging that has stopped, a camera that will not focus, or liquid it was exposed to. Walk-ins are welcome.
2. We Inspect the iPhone
We check the visible damage and the components tied to the symptom. Two iPhones with the same crack can need different work, so the exact model and what else the impact reached are established first.
3. We Explain the Repair and Quote
You get the replacement part, the expected repair time, the price, and any features the work may affect, all explained before you are asked to approve anything.
4. You Decide
You decide whether to go ahead. Nothing is opened until the repair and its price have been explained, and you are free to take the quote away and think about it.
Pricing
How Much Does iPhone Repair Cost?
There is no single repair price that applies to every iPhone. The cost depends on several factors.
Different iPhone generations use different displays, batteries, cameras, charging components, and other parts. The same repair can therefore cost differently between models.
Screen replacement, battery replacement, charging port repair, camera repair, and back glass repair require different parts and different amounts of work.
A cracked screen may be the most visible problem, but the same drop can also affect the frame, camera, or other components. Additional damage can affect both repair cost and repair time.
Parts availability can affect both repair cost and repair time, especially for very new or older iPhone models. CELLTECH inspects the device and provides a quote before repair work begins. Repairs include CELLTECH's 90 day malfunction warranty.
A display assembly is a larger and more expensive component than a battery, so iPhone screen repair usually sits at a different price than battery replacement. Charging port, camera, and back glass work each use their own parts and their own amount of bench time, which is why one flat price cannot cover every iPhone repair.
Price can move in both directions with age. A very recent iPhone can carry a higher part cost while supply is still limited, and a much older model can cost more when the component is harder to source. The exact generation you bring in is one of the larger factors in what the repair costs.
CELLTECH inspects the iPhone and explains the problem before anything is agreed. You hear the repair option, what it involves, and the price first, and you can decide not to continue. Asking what is included, whether more than one component is affected, and what happens if further damage is found keeps the final figure predictable.
Turnaround
How Long Does an iPhone Repair Take?
You may not need to spend the entire day without your iPhone. Many common CELLTECH iPhone repairs can be completed in as little as 20 minutes when the required part is available and no additional damage is found. Same day repair service is also available for many common iPhone problems. Repair time depends on:
- The iPhone model
- The repair required
- Parts availability
- The extent of the damage
Whether more than one component is affected
Common screen and battery repairs are often among the faster services.
Charging port, camera, back glass, and liquid damage repairs may take longer because additional diagnosis or repair work may be required.
Your CELLTECH store can provide a more accurate estimate after confirming the iPhone model and repair required.
Repair or replace
Should I Repair or Replace My iPhone?
A damaged screen, worn battery, charging problem, or camera issue does not automatically mean you need a new iPhone. Repair may make sense when the rest of the device is still working well and the repair cost is reasonable compared with replacement. Repair can be especially convenient when a common problem can be fixed quickly rather than replacing and setting up an entirely new device. Replacement may make more sense when:
- Several major components are damaged.
- The device has severe internal damage.
- The repair cost approaches the value of replacing the device.
- Parts are difficult to obtain.
- The device no longer meets your needs.
- The best decision starts with knowing what is actually wrong and what the repair will cost.
- CELLTECH can inspect the iPhone and provide a repair quote so you can compare your options.
Before your visit
Before You Bring Your iPhone In
A few simple steps can make the repair process easier.
If your iPhone still works, back up important photos, contacts, messages, and other information before repair. You can use iCloud or a computer. Many hardware repairs do not normally require your personal data to be removed, but backing up important information is still recommended.
Some functions may need to be tested after the repair. Access to the device can help confirm that:
The display responds correctly.
Face ID works.
The camera focuses.
The iPhone charges.
Other repaired features work properly.
Security features such as Find My can affect some service or testing situations. If you are unsure whether anything needs to be changed, contact your CELLTECH store before visiting.
If getting the iPhone back quickly is important, ask whether the required part is available for your model before you visit. Turnaround depends on it more than on anything else.
Water resistance is not permanent. It can decrease over time because of wear, physical damage, or device disassembly. Opening an iPhone for repair can also affect its sealing. If water resistance is important to you, ask what sealing process applies to your repair and avoid assuming that a repaired iPhone has the same water resistance it had when new.
Warranty
90 Day Malfunction Warranty on iPhone Repairs
CELLTECH backs repairs with a 90 day malfunction warranty. The warranty is designed to give you confidence that if the repaired component develops a covered malfunction during the 90 day malfunction warranty period, the issue can be reviewed under CELLTECH's warranty terms. The warranty applies to repair related malfunctions covered by the applicable service terms. New accidental damage, new physical damage, or additional liquid exposure are different from a repair malfunction. Before repair begins, CELLTECH can explain how the 90 day malfunction warranty applies to your specific repair. Keep your repair information and receipt in case you need warranty assistance later.

CELLTECH provides iPhone screen replacement for problems including cracked glass, display damage, and touch issues.

Many common screen repairs may be completed in as little as 20 minutes when the required screen is available. Same day service is also available for many supported models. Screen repairs include a 90 day malfunction warranty.
It depends on the condition of the device and which components were damaged. Face ID should be checked before and after repair. If Face ID already does not work, tell the technician before service begins.
CELLTECH provides iPhone battery replacement. If your battery drains quickly, shuts down unexpectedly, or shows significantly reduced battery health, an inspection can help determine whether replacement makes sense. Many common battery replacements can be completed in as little as 20 minutes, depending on the model and parts availability. Same day battery service may also be available. Battery replacement includes a 90 day malfunction warranty.
Not necessarily. Charging problems can come from the cable, adapter, debris in the charging port, connector damage, or another hardware issue. Try another compatible cable and adapter before visiting if possible.
CELLTECH provides charging port repair for iPhones with charging connection problems. The device is inspected first to determine whether the port is actually causing the problem. Same day repair may be available depending on the exact iPhone model and required part. Charging port repairs include a 90 day malfunction warranty.
CELLTECH provides camera repair for front and rear camera problems. The repair required depends on whether the issue involves the camera glass, camera component, or another part. Same day service may be available when the required component is in stock. Camera repairs include a 90 day malfunction warranty.
Back glass repair is available for many iPhone models. The repair process can vary depending on the iPhone generation and extent of the damage. Same day back glass repair may be available depending on the model and parts availability. Back glass repairs include a 90 day malfunction warranty.

No. If the iPhone or charging connection is wet, avoid charging it and allow it to dry. Rice does not repair liquid damage and can introduce additional debris.
Many hardware repairs do not normally require personal data to be removed. However, backing up important information before repair is recommended whenever the device still works.
The cost depends on the exact iPhone model, replacement part, and whether any additional damage is present. CELLTECH can provide a quote after confirming the model and repair required.

Water resistance can decrease over time and can also be affected when a device is opened for repair. Ask about the sealing process used for your repair and avoid assuming that the repaired iPhone has the same water resistance it had when new.
The answer can depend on the iPhone model and repair required. Ask the CELLTECH store what type of part will be installed before approving the repair. You can also ask about: Feature compatibility, Repair configuration, Repair time, Same day availability, The 90 day malfunction warranty.
