Hidamel Smart Watch M3 (Black)

How long does the battery actually last in real-world usage?

The 480mAh battery provides 8 days with heavy usage including frequent notifications, calls and sports tracking. Typical usage with moderate notifications and daily health monitoring extends to 15 days. Power-saving mode can stretch battery life beyond 60 days by disabling non-essential features whilst maintaining basic timekeeping and emergency functions.

Is this watch genuinely waterproof for swimming and diving?

Yes, the 5ATM and IP69K rating means it's waterproof to 50 metres depth. This exceeds most swimming pool depths and supports surface water sports. The fully enclosed ultra-thin case design prevents water ingress even under high pressure conditions. However, avoid hot water exposure like saunas as thermal expansion can affect seals.

How accurate are the health monitoring features compared to medical devices?

Heart rate monitoring shows excellent accuracy when compared to chest strap monitors and medical equipment. Sleep tracking and blood oxygen readings provide reliable trends for fitness monitoring. However, the blood pressure feature should not replace medical-grade equipment for health decisions - it's best used for general wellness tracking rather than clinical purposes.

Can I use this watch without creating an account or sharing personal data?

The KOSPET app works without requiring account creation, protecting your privacy. You can use all watch functions including health tracking, sports modes and notifications without sharing personal information. The app does offer 'Sign up with Apple' as an optional feature, but basic functionality remains available without any registration process.

What happens if the firmware update fails during setup?

Firmware updates can be slow and may appear to hang around 13% completion for extended periods. This is normal behaviour - avoid interrupting the process. If the update fails completely, restart both the watch and smartphone app, ensure strong Bluetooth connection and retry. The watch remains functional even if firmware updates don't complete successfully.

How does the AI voice assistant compare to Siri or Google Assistant?

The built-in voice assistant handles basic commands like making calls, setting alarms, checking weather and controlling music playback. It responds well to clear voice commands but lacks the advanced AI capabilities of smartphone assistants. The main advantage is hands-free operation when your phone isn't accessible, particularly useful during exercise or driving.

Is the watch comfortable for all-day wear given its chunky design?

The watch measures 18.2 x 9.6 x 2.4 cm and weighs 220g, making it substantially larger than typical smartwatches. The titanium construction keeps weight reasonable despite the size. The silicone strap provides adequate comfort, though some users find the strap quality doesn't match the watch's premium construction. The size suits people who prefer substantial timepieces.

Which smartphones are compatible and what features require the app?

The watch pairs with both Android and iOS devices via Bluetooth connectivity. Basic functions like timekeeping, health monitoring and sports tracking work independently. The KOSPET app enables watch face customisation, detailed health data analysis, notification management and firmware updates. Most core features remain accessible without constant smartphone connection.
