02Features
BioCharge energy score
Starts each morning from how you slept, then rises and falls through the day with training, activity and stress. One number that tells you whether to push or hold back.
24/7 heart rate
The BioTracker 6.0 sensor reads every second instead of every few minutes, alongside heart rate variability, blood oxygen, stress and exertion.
Sleep tracking
Light, deep and REM stages, naps over 20 minutes, sleep HRV, breathing quality and a nightly sleep score. Turn on breathing quality in the Zepp App.
Strength training
Start Strength Training and it recognises the movement, then counts reps, sets and rest. If it misses one, pick it from the list in the Zepp App.
HYROX Race mode
An official HYROX mode with run and station splits, plus benchmark tools to track your race fitness over time.
After every workout
VO2 max, training load, training effect and recovery time, so you know what the session did and how long to rest.
Works without your phone
Records on its own and syncs later. It can also stream live heart rate to compatible Amazfit watches, bike computers, gym machines and apps.
Syncs with your apps
Through the free Zepp App: Strava, adidas Running, komoot, Relive, Google Fit and Apple Health. No subscription.
03Sports modes
110 modes in the Zepp App as of October 2026, up from 27 at launch. Pick your favourites in the app so they're one tap away. Zepp keeps adding modes through free updates, so your list may be longer.

06Set up and wear
- Charge it first. Clip the tracker onto the magnetic charging head until it's full, under 2 hours.
- Pair it in the Zepp App. Install the free Zepp App, add the Helio Strap and let it update to the latest firmware.
- Pick your modes. Choose the sports modes you use most in the Zepp App so they're ready to start.
- Wear it right. Snug, not tight, about one finger-width above the wrist bone. For blood oxygen and spot checks, keep your arm still. Want a different strap? Loop, magnetic loop, sport knit and silicone bands all fit. Shop wrist bands
- Try the bicep. For lifting, HIIT and rowing, an upper-arm band gives steadier readings because grip and wrist movement don't get in the way. Shop bicep bands
07Battery and care
Amazfit rates it at up to 10 days with heart rate, blood oxygen and stress monitoring on, sleep breathing tracked every night and three hour-long workouts a week.
Our take
With 4 to 5 workouts a week, plan on 6 to 7 days. Our tip: take it off once a day so your wrist can breathe, and put it on the charger for 10 to 15 minutes while you shower. Do that and it rarely runs low.
Keep it clean. Rinse the strap after a sweaty session and let it air dry. Wipe the sensor window so readings stay accurate.
Mind the heat. Take it off before hot showers, steam rooms and saunas. Steam can weaken the water seal.
