Which basic health-monitoring wearables are known for long battery life and lightweight comfort?

If you’re looking for basic health-monitoring wearables that are known for long battery life and lightweight comfort, these are the usual standouts:

• Fitbit Inspire series (e.g., Inspire 3)
  Lightweight, slim, and typically offers multiple days of battery life. Good for step count, heart rate, sleep, and general health tracking.

• Garmin Vivosmart series
  Usually very light and often has excellent battery life compared with many smartwatches. Good for basic wellness tracking.

• Xiaomi Mi Band / Smart Band series
  Known for being small, light, and inexpensive, with very long battery life. Covers essentials like heart rate, sleep, and activity tracking.

• Amazfit Band series
  Another lightweight option with strong battery life and basic health features.

• WHOOP strap
  Comfortable and lightweight, though it’s more focused on recovery/strain than simple step tracking. Battery life is decent, and it’s designed for all-day wear.

If you want, I can also narrow these down by:

1. best battery life,
2. most comfortable, or
3. best budget option.
