Testing Process
That Goes the Extra Mile
Every device that enters our lab undergoes a rigorous multi-step testing procedure. From thorough pre-repair diagnostics to final quality assurance checks, our process ensures that nothing is missed — so you get a device that works like new, and stays that way.
Pre-Repair Test
Thorough checks to confirm issues and spot hidden faults.
Targeted Testing
Extra tests for specific repairs (e.g., battery or LCD).
Post-Repair Test
Same full test again, now confirming all faults are gone.
Quality Check
Final high-standard check by our quality manager.

What is a diagnostic and why is it necessary?
A diagnostic is the process of testing, measuring, and analysing your device to find out exactly what is wrong. At iCorrect, it is not a quick scan or guesswork. We test at logic board level and component level so you get a definitive answer, not a vague guess.
What types of issues require a diagnostic first?
Diagnostics are essential when the fault is unclear or could have multiple causes. Common examples include power failures, battery not charging, no display, random shutdowns, overheating, no sound, camera failures, or post-liquid damage.
How much does a diagnostic cost?
Diagnostics start from £29 for Apple Watch, £39 for iPhone, and £49 for iPad and MacBook. This includes all testing, disassembly, measurements, and a full report. If the fault is obvious, we may go straight to repair and waive the diagnostic fee.
What do I get after the diagnostic?
You receive a clear breakdown of the fault, supporting test data, photos if applicable, and a confirmed quote to complete the repair. If you choose not to proceed, your device is returned reassembled or you can recycle it with us.
How long does a diagnostic take?`
Diagnostics usually take 1 to 2 working days for iPhone and Apple Watch, and 2 to 3 working days for iPad and MacBook, depending on complexity and parts required. Express options are available on request.
Can diagnostics be done while I wait or same day?
Some basic tests can be done while you wait, but full diagnostics that involve internal testing, DC power injection, and microscope analysis require more time. We prioritise accuracy over speed.
Will I be charged if you can’t repair the device?
Yes, the diagnostic fee still applies because it covers the full testing process. However, if we determine the device is unrepairable, we can offer a trade-in value or data recovery options where possible.
What if another shop has already looked at my device?
That is fine. In fact, we regularly diagnose failed repairs or identify faults that other shops missed. Our diagnostics go deeper than most, especially when logic board work is involved.
Do diagnostics void my Apple warranty?
If your device is already damaged, it is likely out of Apple warranty. Apple typically considers liquid damage, screen cracks, or internal modifications as voiding the warranty. We are transparent and will always advise you before proceeding.
Is diagnostic testing safe for my data?
Yes. Our process is non-destructive and we always prioritise data integrity. We do not wipe your device, and we take every precaution to protect your information during testing and repair.
