## FAQs
### Q: What is the iPhone 5s model A1533?
A: It is a hardware model identifier for a device in Apple’s iPhone 5S series, commonly referenced as A1533. It designates a particular production/configuration of the iPhone 5S family.

### Q: What regulatory identifiers does model A1533 have?
A: The model A1533 lists FCC product code -E2642A and radio equipment list certification number 579C-E2642B. These identifiers are used for regulatory and certification records.

### Q: What are the SAR (radiation exposure) values for A1533?
A: Documented SAR values include 1.18 W/kg over 1 g tissue (head and body determinations), 0.93 W/kg over 10 g tissue (head), and 0.99 W/kg over 10 g tissue (body). These values are referenced in Apple’s RF exposure documentation (record date 2019-09-03).

## Why It Matters
Identifying the specific model A1533 within the iPhone 5S series matters for regulatory compliance, safety information, and service or parts compatibility. Regulatory identifiers such as the FCC product code and radio equipment certification number are used by authorities and service providers to verify approvals and permitted radio operation. The documented specific absorption rate (SAR) values give consumers and regulators measurable data about radio-frequency exposure for that exact model. Classification as a distinct smartphone model also helps in software support, warranty, repair, and resale contexts where precise hardware identification is required. In short, model-level identifiers like A1533 provide the factual basis for technical documentation, safety disclosures, and administrative processes that surround a specific production variant of a widely distributed consumer device.

## Notable For
