A suspected faulty charging component should trigger a clear evidence record—not an immediate accusation that the supplier caused the device’s problem. Charging failures can have several causes, including issues outside the replacement component. The purpose of a supplier defect report is to let both sides review the same part, order, observations and test scope before deciding the next step.
This template is intended for B2B procurement, repair and refurbishment teams. It does not promise a return, replacement or refund. The applicable written supplier agreement controls the commercial process.
Identify the affected material precisely
Start with the purchase order, invoice or shipment reference, supplier SKU, description and all lot or batch markings actually supplied. State the affected quantity and whether the items are unused, installed, removed or awaiting inspection. If you have an internal receiving code, show how it links to the original shipment. Do not substitute an internal code for a nonexistent manufacturer batch number.
Record the exact device model and version used during any authorized evaluation, but exclude customer-identifying information from the supplier-facing file. If images are necessary, crop or redact serial numbers, account screens, personal messages and customer labels. The supplier normally needs the component and technical observation, not the customer’s private data.
Separate observation, procedure and conclusion
Write the observed event in factual language: “After an authorized replacement, wired charging remained intermittent during the recorded check.” Avoid an unproven conclusion such as “Supplier sent bad ports.” Include whether the behavior was present before the part was fitted, what was actually tested and which conditions were not assessed.
The relevant repair method must come from the device manufacturer’s documentation and the technician’s authorized work scope. Apple’s iPhone 15 and iPhone 16 manuals are examples of model-specific repair references. This article does not prescribe energized circuit tests, pin probing or invasive diagnostic procedures.
ESD and handling context also matter. The EOS/ESD Association’s control overview explains why sensitive electronics require appropriate handling and packaging controls. Document the handling process actually used instead of making an unsupported claim that handling could not have affected the part.

Example supplier note (fictional template)
Subject: Charging assembly review request — PO [reference], SKU [reference]
We received [quantity] units identified as [supplier SKU] on [date]. During an authorized assessment of [exact device model], we observed [specific behavior] under [recorded condition]. The technical cause has not been established. Attached are the lot label (if provided), approved work record, cropped photos and a list of checks actually performed. Please confirm the applicable claim procedure, any handling instructions and the information you require for review. No return authorization has been assumed.
This is a fictional format. Do not insert real customer data or send it to a supplier without checking the actual records and agreement.
Preserve the review trail
Maintain a simple timeline: first observation, date evidence collected, supplier contacted, response received, units held or returned, and final disposition. If the supplier asks for additional tests, require confirmation that the request is safe, applicable to the device and within the shop’s approved methods. Do not destroy or rework disputed material before the handling terms and evidence needs are understood.
A disagreement may ultimately involve parts identity, installation, device condition or commercial policy. A useful report keeps these possibilities separate and documents what has—not what has not—been demonstrated.

Next action: Complete the factual report, attach only necessary redacted evidence and request the supplier’s written case instructions. Record the outcome without assuming fault or a guaranteed remedy.
Send a parts inquiry
Use MRG’s Get a Sample and Parts Inquiry page to describe the model, the exact component and the evidence you need reviewed.
