Samsung Galaxy Watch 3 review: specs and price

The Samsung Galaxy Watch 3 is a highly customizable smartwatch with tens of thousands of different faces and wristbands to choose from. The battery easily lasts the day and can be fully charged in a couple of hours. Plus, if you run low on battery, you can wirelessly charge it from a compatible Galaxy smartphone with PowerShare. 

It has tons of great features that many smartwatches don’t have, such as ECG technology to monitor your heart’s electrical activity, blood oxygenation tracking, and fall detection. As well as that, you get all of the standard fitness tracking you’d expect, including heart rate monitoring, hydration tracking, and sleep tracking.

All of this information is delivered to you by a gorgeous 1.2” Super AMOLED display, which features deep blacks and vibrant colors. If you’re looking for a stylish GPS smartwatch with premium features (and without the premium price), the Galaxy Watch 3 is a great choice.

Excelente en todo excepto la batería porque difícilmente llegas a 2 días completos y si activas el Always On Display menos. Lo que más pierdes es que si sueles cargarlo por la noche pues tendrás tu análisis de sueño un día si y al otro no.

Pros

  • Diseño
  • Con cambio de correas puedes tenerlo en muchos looks
  • Muchas y buenas carátulas
  • Muchas actividades deportivas
  • Medición de muchos temas de salud
  • Opción de activar solo notificaciones importantes

Cons

  • El registro de sueño podría ser mejor
  • Contador de calorías parece inexacto
