Battery life is up to seven days depending on usage. Charge using the included clip-style USB cable: pinch the clip to attach to the device contacts, plug into a USB power source, and charge until full. Keep contacts clean and dry to avoid corrosion.
Is this answer helpful?
Yes. The vivosmart 4 supports pool swimming, walking, running, strength training, yoga, stair stepper and other activities. Start a timed activity on the device for best results; heart rate is not available while swimming.

Body Battery estimates your energy reserves on a 0–100 scale by analyzing heart rate variability, stress, sleep quality, and activity. It trends over time and updates when you sync with Garmin Connect. Wearing the device while sleeping improves accuracy.
Is this answer helpful?
Wear the device on your non-dominant wrist, keep it snug above the wrist bone, and clean sensors regularly. Warm up before workouts for stable heart rate readings. For step accuracy, avoid carrying out activities that mimic steps or place the device in a pocket when using hands extensively.

Open Garmin Connect, go to Garmin Devices > your device > Activity Tracking > Pulse Ox, and enable Pulse Ox Sleep Tracking. The device can record up to several hours of SpO2 data during sleep; unusual sleep positions may affect readings.

Product Description
Garmin vivosmart 4 S/M activity tracker black Manual
Overview
The Garmin vivosmart 4 S/M activity tracker in black is a slim, wrist-based fitness band that blends discreet design with advanced health and activity monitoring. It tracks steps, floors climbed, intensity minutes, calories, distance, sleep, stress, and heart rate, while offering pulse oximeter (SpO2) measurements to gauge blood oxygen saturation. The device pairs with the Garmin Connect Mobile app to sync data, customize settings and widgets, and receive notifications from a paired smartphone.
Key Features and Use
Designed to be worn just above the wrist bone, the vivosmart 4 provides continuous wrist-based heart rate monitoring, Body Battery energy tracking, and stress-level estimation via heart rate variability. It supports guided breathing (relaxation timer), Move IQ automatic activity detection, and intensity minute tracking to help meet CDC and WHO exercise guidelines. Timed activities like walking, running, swimming, strength training, yoga, and Toe-to-Toe step challenges are recorded and saved to Garmin Connect for deeper analysis.
The band includes a pulse oximeter for spot SpO2 readings or optional sleep-time monitoring, helping users understand how their body adapts to exercise and recovery. VO2 max estimates are available after a 15-minute brisk walk or run and use heart rate data to assess aerobic fitness. The device can broadcast heart rate via ANT+ to compatible Garmin devices, and supports music controls, phone finding, and notifications when paired via Bluetooth.
Practical Details
Charging is via a clip-style USB cable; the internal lithium-polymer battery lasts up to seven days depending on usage. The device is swim-rated to 50 meters and uses a touchscreen with wrist gestures and double-tap controls. Many device behaviors and alerts — including brightness, vibration, notification filtering, Do Not Disturb, Auto Lap, and Pulse Ox sleep tracking — are configurable through Garmin Connect or Garmin Express on a computer.
Tips for Accurate Data
- Wear snugly above the wrist bone and remain still for pulse oximeter readings.
- Keep sensors and charging contacts clean and dry; rinse after exposure to chlorine, salt, or lotions.
- Sync regularly with Garmin Connect to update time, Body Battery trends, and software.
Notes
- Not a medical device; SpO2 and heart rate metrics are estimates for wellness and fitness use.
- Some features (Pulse Ox sleep tracking, broadcasting, continuous HR) reduce battery life.
- Device compatibility requires Bluetooth Smart; check Garmin resources for smartphone support.
