S20S FAQs

Can the S20S make and receive phone calls?

No. The S20S shows incoming call alerts on your wrist, but the call itself is answered on your phone. If you want to talk through your watch, browse our Bluetooth calling smartwatches.

Is the S20S waterproof?

It is rated IP68 for dust and water resistance, so rain, sweat and hand washing are fine. Avoid hot showers, saunas, sea water and diving, as heat and pressure can damage the seals.

How long does the battery last?

Expect around 7 days of typical use from its 230 mAh polymer battery. Bright screens, always-on display, frequent calls and continuous heart rate tracking use more power. See our smartwatch battery life guide for tips.

Does the S20S work with iPhone and Android?

Yes, it is compatible with iOS and Android phones via the companion app.

Are the health readings medically accurate?

No smartwatch in this range is a medical device. Heart rate, blood oxygen, blood pressure, temperature and similar readings are estimates to help you spot trends in your general fitness and wellbeing. They are not suitable for diagnosing or managing a medical condition, so always speak to a healthcare professional about health concerns.
