- Activate NFC payments within the app and complete registration after verification by your bank.
- Customize watch faces, notifications, and health monitoring preferences.
Charging — recommended charger and practice
- Usual method: Magnetic puck provided; powered via USB.
- Additional adapter recommendation: 18W USB‑C PD adapter for reliable charging and portability. 18–30W is sufficient; higher wattages offer no significant improvement.
- Instructions for proper charging: Charge at room temperature, avoid extreme temperatures, do not leave the device continuously at 100% for weeks; prefer cycles of 20–80% for battery longevity.
Energy consumption / class
Wearables are not included in EU energy label classes such as household appliances. Energy consumption depends on usage profile (AOD, GNSS, continuous SpO2). The reported autonomy values provide a functional estimate.
Warranty, DOA, and returns process (consumers & professionals)
- EU legal guarantee: 24 months for consumers (legal warranty).
- Manufacturer's warranty: Typically 12–24 months depending on distributor/country; check the warranty certificate in the package.
- DOA (Dead on Arrival): Report immediately to the seller (usually 14–30 days policy) with receipts/photos; retailers issue RMA or immediate replacement.
- Returns: EU 14-day cooling-off period (some customized services are excluded). Store return policies (see us) supplement your legal rights with a standard 14–30 day return period.
- Professionals (B2B): Trade agreements often apply; not all consumer protections always apply; terms must be explicitly stated on the invoice. We recommend requesting a pre-existing RMA/SLA agreement.
- Legal guarantee rating: 24 months (EU) — this is the legal minimum for consumers.
Defect statistics & frequency in the first 2 months
In the Watch S4 generation, the issues reported mainly concern software/firmware (pairing, notifications) and isolated DOA cases. Mass hardware defects within the first two months are not recorded as a widespread trend; the DOA rate is low and usually covered by RMA.
