The Garmin Vivoactive 4S is a fitness smartwatch that requires no smartphone connection to function optimally. GPS is built in, and you can store offline music on the watch and play it through your Bluetooth headphones. You can even make payments with Garmin Pay. If you’re looking for a fitness smartwatch, you can’t go wrong with the Garmin Vivoactive 4S.
The Vivoactive 4s has a thin metal casing, and the two side buttons are also made of metal. The Vivoactive 4s has an additional side button for lap, back, and menu access. The display itself is a backlit, transflective memory-in-pixel panel that uses technology that allows it to consume less power compared to LCD panels. This is one of the hardware factors that give the Vivoactive 4s up to seven days of battery life. The quality of the display is essentially the same as previous Vivoactive models, so the watch face is always easy to see and can be easily read even when running outdoors in the sun.
The Vivoactive 4s is packed with fitness sensors: Accelerometer, gyroscope, altimeter, optical heart rate monitor, integrated GPS/Galileo/GLONASS, pulse oximeter, compass, and a thermometer. All of these sensors are updated with new sensors to provide even more accurate and efficient performance. The Vivoactive 4s also has storage for music on board which Garmin has significantly improved over the past year or two. This makes it a great choice for people who want to stay connected while working out or playing sports.
The Vivoactive 4s has an optional all-day pulse oximetry sensor that allows you to measure the oxygen level in your blood based on the heart rate and respiration data you collect. For most healthy people, a pulse ox reading close to 100 will be displayed in the Garmin Connect app after the pulse ox sensors have collected enough data.
