Samsung Galaxy Watch8 44 mm Bluetooth (SM-L330) / Amazfit Bip 6

Always On Display keeps the watch face visible but shortens battery life; when off, the screen wakes on wrist raise.

2000 nits is the peak only, used briefly to improve readability in sunlight.

Sapphire crystal resists scratches better than ordinary glass. The 8.6 mm thickness excludes the sensor bump on the back.

32 GB of storage is enough to keep music and apps on the watch for phone-free runs.

The watch charges only wirelessly; it must align with Samsung’s charging puck, and some wireless chargers may not sit flat because of the band.

The electrical heart signal enables ECG and bioelectrical impedance enables body composition readings. ECG and blood pressure need a Samsung phone and country approval.

The PPG sensor tracks blood flow under the skin with light to measure heart rate, blood-oxygen saturation and heart-rate variability during sleep. These readings are not for medical diagnosis.

Antioxidant Index is measured by holding a fingertip on the sensor for about five seconds; Vascular Load needs the watch to be worn to sleep on at least 3 of the last 14 days. These are wellness indicators, not medical diagnoses.

The L5 band helps reduce route drift caused by reflections among tall buildings and trees.

On the Bluetooth model calls and notifications work while connected to the phone; NFC contactless payments depend on country and bank.

5ATM means water resistance suitable for swimming, not diving or high-speed water sports. MIL-STD-810H refers to selected environmental tests from the military standard and is no guarantee against impacts.

Gemini can act in Samsung Health, Calendar and Clock via voice; availability varies by device, language and country.

It cannot be used with an iPhone.

The Zepp Flow voice assistant works only in selected countries and regions.

The standard 22 mm strap width lets third-party straps be fitted.

According to Amazfit the watch withstands the pressure of 50 metres of still water for up to 10 minutes; there are pool and open-water swimming modes.

A full charge takes 1.5–2.5 hours. The box includes a magnetic charging head but no USB-C cable; any USB-C cable can be used.

Built-in GPS lets runs and rides be recorded without the phone; turn-by-turn direction prompts are supported.

Calls go through the phone over Bluetooth; the watch has no cellular link or Wi-Fi. Third-party music apps cannot be installed, but music playing on the phone can be controlled.

Chest-strap heart-rate monitors, running and cycling power meters and cycling speed/cadence sensors can be paired. Data can be exported to apps such as Strava, komoot, Google Fit and Apple Health; there is no sync with Samsung Health or MyFitnessPal.
