iPhone Won’t Turn On · Diagnosed by Post · UK-Wide
iPhone won’t turn on?
A £40 diagnostic finds out why — and comes off the repair.
Black screen, boot loop, stuck on the Apple logo, or completely dead? A phone that won’t turn on is rarely “gone”. It’s usually a battery, a screen, a charging fault or software — and each has a very different price. We find out which, then quote.

How much does it cost to fix an iPhone that won’t turn on?
There’s no single price because there’s no single cause. It starts with a fixed £40 diagnostic: we check power, battery, charging circuit, screen and software, and tell you exactly what it needs. Go ahead and the £40 comes off that repair’s normal fixed price. If it’s beyond economic repair, that’s all you pay, and we return the phone free — or buy it from you for parts.
If the cause is the screen, battery or charging port, you pay that repair’s normal fixed price with the diagnostic taken off. If it’s software, the diagnostic usually is the repair.
If you already know it’s the screen or battery, quote that repair directly instead. Run the quote tool — it confirms the exact repair in under 2 minutes.

The four things that make an iPhone “dead”
Most phones that arrive as “won’t turn on” leave as one of these four repairs. The diagnostic is how we find out which — without guessing at your expense.
A phone that vibrates or rings but shows nothing has a dead display, not a dead phone. Fixed at the normal screen price — see the screen repair page.
A worn or swollen battery can drop below the voltage the phone needs to boot. Replaced at the normal battery price, health restored.
If no power is getting in, nothing turns on. A blocked or failed port — or a damaged charging circuit — is diagnosed before anything is replaced.
Boot loops, failed updates and “iPhone disabled” are often recoverable with a restore. You’ll lose data unless you have a backup — we tell you before we start.

iPhone won’t turn on repair FAQ
Common questions
Both are genuine options here. The diagnostic tells you the real repair cost so you can decide. If you’d rather not repair, we buy iPhones that won’t turn on in any condition and pay by bank transfer the same day it arrives.
If the fault is hardware — screen, battery, charging — no, your data is untouched. If the phone needs a software restore, the data is wiped unless you have an iCloud or computer backup. We always tell you before a restore.
Some board faults are repairable, some aren’t economical. Either way you get a straight answer. If it can’t be fixed, the £40 is the only charge and the phone comes back free — or we buy it for parts.
Usually the same day the phone arrives. You get a WhatsApp message with what we found and the price, and nothing is done until you say yes.
