iPhone 12 Pro Max not charging? Test the path before replacing the port.
Your iPhone 12 Pro Max won’t charge, or only charges when the cable sits just right? We’ll check the cable connection, battery and charging circuitry, then explain the fault and cost before you decide on repair.
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.
Model-specific context
Separate Lightning charging from wireless charging
The iPhone 12 Pro Max supports both Lightning and wireless charging. If one route worked and the other stopped, include that detail: it helps decide which path to inspect first. A wireless charge does not prove every battery or board circuit is healthy. Tell us whether computer detection through the cable also changed.

The symptom
Charging behaviours worth describing
Small details can separate a worn port from a fault further along the charging path:
- It charges only when the cable is held at an angle
- Known-good cables produce no charge or an accessory warning
- The battery stays at one percentage or drains while connected
- The phone became completely flat after charging became unreliable
What the diagnostic checks
What we check on your iPhone 12 Pro Max.
- Inspect the Lightning port and flex for debris, corrosion and mechanical damage
- Measure charging behaviour with known-good equipment before replacing parts
- Test the negotiation and power path between the port, charging circuitry and battery
- Identify whether the viable route is a port repair, board repair or a different fault
We’ll explain what we find in writing and quote for the work we can offer. Your options depend on the device’s condition, our test results and the parts available.
How the sequence changes the starting point
A loose Lightning cable, a firmly connected cable with no charge and a phone that charges but quickly switches off are different complaints. Tell us which happened first. A phone that only became unresponsive after several days of unreliable charging may need a charging-path investigation as well as battery checks.
What a useful charging finding should distinguish
The finding should explain whether power reaches the phone, whether the battery accepts it and whether the connection stays reliable. If the symptom was not reproduced during assessment, that uncertainty needs to be recorded. A brief successful charge alone does not explain an intermittent fault that occurs when the cable moves.
Before you post it
Protect the device and the data while deciding.
- Try one known-good cable and charger, then record exactly what happens
- Do not force a cable into a damaged or contaminated port
- Include any history of drops, liquid exposure or previous port work in the booking

Tell us what’s happening with your iPhone 12 Pro Max. We’ll assess it at our Tyneside lab for £35 and explain your options before you decide on repair.
A charging assessment is not a promise of a port replacement
The port is one possible cause, not the diagnosis. Parts availability, board condition and the result of the charging-path tests determine the repair route. The £35 assessment gives you the findings and quote before work proceeds.
Common questions
iPhone 12 Pro Max not charging FAQ
Is an iPhone 12 Pro Max that charges at an angle just a dirty port?
Debris and worn contacts are possible, but corrosion, flex damage and board-level charging faults can look similar. We inspect and test the path before recommending a part.
Can a charging fault make the phone look dead?
Yes. If the battery becomes fully flat because the charging path has failed, the phone may stop showing useful signs of life. Describe the sequence when booking so the assessment covers both symptoms.
Should I clean the Lightning port myself?
Avoid metal tools and aggressive cleaning. If the port is damaged, wet or contaminated, stop forcing cables into it and describe the condition to support before posting.
