Build Quality Feel:
Solid for the price range. Not luxury-level, but sturdy enough for daily use.
4. Display Quality — The Star of the Show
The 1.96-inch AMOLED curved screen is the highlight of the Haylou S8.
Why the display is so good:
- Deep contrast
- Bright enough outdoors
- High pixel density
- Smooth animations
- Curved edges give a premium feeling
Even in sunlight, the text stays readable — something most budget smartwatches struggle with.
5. Bluetooth Calling Performance
This is where the S8 surprised me. Thanks to the dual Bluetooth chip, the calling experience feels stable.
Call Quality:
- Voice is clear
- Mic picks up your voice well
- No random disconnects
- Works up to 8–10 meters away from the phone
You can store contacts, check call history, and dial numbers directly from the watch.
For the price, this calling performance is genuinely impressive.
6. Health & Fitness Tracking Accuracy
- The watch includes:
- Heart rate monitoring
- SpO₂ measurement
- Sleep tracking
- Stress levels
- Step counting
- Blood pressure estimation
Accuracy
- Heart rate → fairly accurate for normal usage
- SpO₂ → matches typical fingertip oximeter results within ±2%
- Sleep tracking → detects deep/light sleep well
- BP estimation → should be used only for reference, not medical use
Sports tracking is fine for walking, running, cycling, and general workouts. Accuracy is acceptable, especially considering the price range.
7. Battery Life Test
Haylou claims up to 8 days of usage, and that’s mostly true if you use it normally.
Test results:
- Normal use (notifications + HR + sleep) → 6.5–7 days
- Heavy use (always-on display + calling) → 2.5–3 days
- Standby → 20 days (claimed)
Charging time is about 3 hours, which is a bit slow, but manageable overnight.

The Haylou Watch App is simple and lightweight.
You get:
- Health dashboard
