iPhone charging faults — the port is only the first suspect.
Most people assume a charging fault means a worn port. Sometimes it does. Just as often the fault sits behind the port, in the charging IC or power path — which is why replacing the port blindly so often disappoints. We test the path, then fix the actual fault.
The fixed £35 diagnostic covers the assessment described below and both-way UK tracked shipping. If you approve the repair quote, the fee is deducted from that quote. No repair work starts without your approval.
The symptom
Charging symptoms worth reading closely
The pattern of the failure says a lot about where it lives:
- Not charging at all from any cable or charger
- Charging only at certain angles, or only from certain cables
- “Accessory not supported” messages with known-good cables
- Draining while plugged in, or stuck at a fixed percentage
Likely causes
Where charging faults actually live
The port itself
Debris, corrosion or worn pins — the honest cheap fix when it really is the fault. Diagnosis confirms it rather than assuming it.
The charging IC
The IC that negotiates charging (widely known as Tristar/Hydra on iPhones) fails frequently — often after cheap chargers or car adapters. Classic sign: good cable, good port, still no charge.
Power-path components
Failed capacitors or damaged traces between the port and the battery can block or throttle charge current. Only bench measurement finds these.
Battery communication
If the phone cannot read the battery correctly it may refuse to charge it. The symptom looks like a charging fault; the cause is elsewhere.
What the diagnostic finds
What the £35 assessment actually does.
- Charge-current measurement on bench power to see what the phone actually accepts
- Charging-path testing from port through IC to battery, not just a visual port check
- USB negotiation testing to catch IC-level faults that mimic cable problems
- A written finding naming the failed stage and the exact repair quote
The findings arrive in writing with the quote. You approve, decline or extend — the fee terms are explained in the FAQ.
Describe the fault once — then approve the next step.
The booking form records what happened so the bench sees the same details. Completed repairs carry a 90-day warranty on the specific fault repaired.

iPhone charging fault FAQ
How do I know if it's the port or something deeper?
You usually can't from the outside — that's the honest answer. A port that charges at certain angles suggests mechanical wear; refusing all known-good chargers points deeper. Diagnosis measures the charging path and removes the guesswork.
Can a cheap charger really damage an iPhone?
Yes. Poorly regulated chargers and car adapters are a well-known killer of the charging IC. If the fault appeared after using a non-standard charger, mention it at booking — it points the diagnosis.
My iPhone is also dead now, not just refusing to charge. Same service?
Yes — a failed charging path eventually leaves the battery empty, so 'won't charge' becomes 'won't turn on'. Book it and describe the sequence; the diagnostic covers both.
