Samsung Galaxy Watch 4 (44mm, Black)

How accurate is the body composition analysis feature?

The body composition analysis uses bioelectrical impedance technology similar to professional body composition scales. Whilst it provides useful trends and relative measurements, factors like hydration levels and recent exercise can affect readings. For most accurate results, take measurements at the same time daily under consistent conditions. The feature works best for tracking changes over time rather than absolute precision.

Can I use this watch for swimming and water sports?

Yes, the watch has 5ATM water resistance rating, meaning it can withstand pressure equivalent to 50 metres underwater. This makes it suitable for swimming, snorkelling and most water sports. However, it's not recommended for high-pressure water activities like jet skiing or deep-sea diving. The water resistance also protects against rain, handwashing and accidental splashes during daily use.

How long does the battery last with typical usage?

Battery life varies depending on usage patterns, but typically lasts 1-2 days with moderate use including notifications, health monitoring and occasional GPS tracking. Heavy GPS usage, always-on display and frequent app usage will reduce battery life. The watch supports fast wireless charging, reaching 45% charge in about 30 minutes, making it convenient to top up during daily routines.

Does this work with iPhone or only Android phones?

The Galaxy Watch 4 is designed primarily for Android smartphones and requires the Galaxy Watch app for full functionality. Whilst some basic features may work with iPhones through third-party apps, you'll miss key features like Samsung Pay, full notification support and seamless integration. For the complete experience, pairing with an Android device running Android 6.0 or later is recommended.

What health metrics can this watch monitor continuously?

The watch continuously monitors heart rate, stress levels and blood oxygen saturation throughout the day. It also tracks steps, calories burned and active minutes automatically. Sleep tracking runs overnight to monitor sleep stages and quality. Additional on-demand measurements include ECG readings, body composition analysis and blood pressure monitoring when paired with compatible Samsung smartphones.

How many workout types does the watch recognise automatically?

The watch can automatically detect and track over 90 different workout types including running, walking, cycling, swimming, rowing and elliptical training. It uses motion sensors and heart rate data to identify when you start exercising and begins recording metrics automatically. You can also manually start workouts for more precise tracking and access to additional exercise-specific features and coaching.

Can I make phone calls directly from the watch?

Yes, when connected to your smartphone via Bluetooth, you can make and receive calls directly through the watch using its built-in microphone and speaker. The audio quality is suitable for short conversations, though longer calls are more comfortable using your phone or Bluetooth headphones. The watch also supports text messaging and voice-to-text responses for quick communication.

What apps are available for download on this watch?

The watch runs Wear OS with access to the Google Play Store, offering thousands of apps including fitness trackers, music streaming services, navigation apps and productivity tools. Popular apps include Spotify, Google Maps, WhatsApp and various fitness applications. Samsung also provides exclusive apps like Samsung Pay, Samsung Health and Galaxy-specific features that integrate seamlessly with Samsung smartphones.
